The Spectator periodicals are a popular journalistic genre of the 18^th century which (co-)constructs and preserves the cultural knowledge of its time in general and gender-specific knowledge in particular, propagating a heteronormative society. As a broadly effective medium circulating from England throughout the Western world, the Spectator periodicals also promote the transcultural dissemination of a transforming understanding of gender,1 in conjunction with the changing values, norms, and practices among the constituting middle classes.

The quantitative-statistical as well as the discourse-analytical and interpretative study on gender-specific ways of worldmaking in the French- and Spanish-language Spectator periodicals (cf. Völkl 2022) reveals that the French-language periodicals of the first half of the 18^th century contribute to the dissemination of the notion of a ‘natural’ gender difference which primarily appears together with a discourse of character and/or physical differences. From the middle of the century onwards, in which the periodicals are also published in Spain,2 the discourse of difference is expanded to include the aspect of complementarity, finally recognizing woman and man as a mutually complementary entity. Due to her alleged closeness to nature, in this discourse of complementarity, the woman is hierarchically placed under the authority of man, whose assumed higher ability to reason is considered superior.

In order to disseminate the discourses of difference and complementarity, the French- and Spanish-language periodicals draw particularly on the notion of virtue (French: vertu; Spanish: virtud). According to research on the Enlightenment period, this term generally functions as a gender-specific key concept (‘geschlechtsspezifischer Leitbegriff’ according to Pabst 2007) and stands in opposition to the notion of vice (French: vice; Spanish: vicio) (cf. Bolufer Peruga 1998, Kilian 2002, Schaufler 2002, Steinbrügge 1987). Furthermore, the discourse on virtues and vices is combined with positive and negative (character) traits and behavioral patterns which are hierarchized and assessed as worthy or not worthy of emulation. Among the ignoble vices on the one hand, one can find, e.g., hypocrisy, idleness, vanity, or jealousy which should be avoided by women and men alike (and thus remain gender-unspecific). The virtues worthy of emulation on the other hand, are constructed in a gender-specific way, with the ‘female’ virtues revolving around concepts such as decency, modesty, kindness, shamefulness, beauty, or (a specific female) education, while the ‘male’ virtues only include (a specific male) education, honesty, and reason. In order to make the large number of virtues and vices known to the Spectator audience – which decidedly also included women – they are incorporated into gender-stereotypical models, illustrating ideal images or warning examples. E.g., the characteristics of egoism and vanity which are considered vicious, are linked to the stereotypical models of the coquette or the fop and contrasted with virtuous models of women and men. The gender-stereotypical models with their manifold virtues and vices are enveloped into countless (exemplary) stories from everyday life and in (character) portraits which are narratively woven into the plot (cf. Völkl 2022, 282–286).

To quantitatively verify these observations on the (entire) Spectator corpus, a topic modeling analysis was carried out in the course of the project Distant Spectators. Distant Reading for Periodicals of the Enlightenment (DiSpecs) (Scholger et al. 2019–2021) after which special attention was given to the interpretation of those topics that stand out from a gender-theoretical perspective. The computed values and their visual representation were intended to provide a new perspective on the corpus and create new theories and questions. The following chapters first describe the related work, the research corpus, and the methodology before presenting the results and findings of the topic modeling analysis with regard to gender-specific discourse in the Spectator periodicals.

Topic modeling has become an integral part of the range of methods used in digital humanities, and more specifically in computational literary studies. According to the survey of Du, it has been increasingly used since 2011 (cf. Du 2019). In the field of historical newspapers and periodicals, topic modeling was conducted for analyzing the social and political life of Civil War Richmond based on the Richmond Daily Dispatch (cf. Nelson 2020) and for investigating the discourse dynamics in historical newspapers published in Finland between 1854 and 1917 (cf. Marjanen et al. 2020). Regarding the Enlightenment period, Schöch applied topic modeling on French Classical and Enlightenment drama for sub-genre classification (cf. Schöch 2017), and Roe et al. analyzed the discursive structure in the Encyclopédie of Denis Diderot and Jean le Rond d’Alembert (cf. Roe et al. 2016).

A persistent point of criticism in the application of topic modeling is the lack of explainability and comprehensibility of the results (cf. Hu et al. 2014, 424–425, Liu et al. 2017, 1–2). This is very much related to the lack of documentation of single working steps and parameters applied in the topic modeling process as Du pointed out (cf. Du 2019): In order to guarantee the reproducibility of the results, it is crucial to have details on the number of documents, the conducted pre-processing steps, the number of topics and iterations selected in the actual modeling process, etc. To address this criticism, this contribution aims to not only provide the results of our topic modeling analyses, but also to transparently document the workflow that led to them.

While the Spectators have been studied through close reading as a work-centered approach, there have been no previous activities that explore this genre from a distant reading perspective. For this reason, the project DiSpecs engaged in text mining of the collection of 3,863 periodical issues in six languages,3 assembled and edited during the digital scholarly edition project The ‘Spectators’ in the International Context (Ertler et al. 2011–2021). In the DiSpecs project, topic modeling was used for investigating the semantic and stylistic structure.

What proved to be very useful for the analysis was the fact that the documents were already available in XML/TEI format (TEI Consortium 2021). This includes not only the annotation of metadata and structural elements (e.g., paragraphs and pagination), but also narrative forms (e.g., self-portrait, letter/letter to the editor, fable) and narrative levels of representation,4 as well as subjects (e.g., ‘Idea of man’, ‘Nature’, ‘Economy’, ‘Theatre Literature Arts’), mentioned places, person names, and intellectual works. The annotation format provided through the application of the Text Encoding Initiative (TEI) standard enables easier extraction of certain structures of the data for the analysis (e.g., metadata, headings, footnotes, editorial comments) with the possibility to separate issues into paragraphs and to exclude parts or whole issues during the pre-processing of the data which will be explained closer in subsection 4.2.

The unsupervised probabilistic topic modeling method aims to identify hidden thematic structures in large text collections (cf. Blei 2020, 8) which means that the algorithm recognizes patterns in the data without having a training subset or a desired output (cf. Alloghani et al. 2020, 4). The resulting topics usually consist of thematically related words, i.e., tokens. However, some topics have structural rather than thematic significance. They can provide insight into the writing style of the author, terms typical for a genre, adjectives describing a matter, repeatedly mentioned places or persons. This is due to the fact that the method’s algorithms measure the co-occurrence of words, following statistical assumptions, meaning that if the same words often occur together in documents, they are most likely thematically related (cf. Blei 2020, 9).

Multiple algorithms were developed for topic modeling, but one of the most prominent, and the one we used in our analysis, is Latent Dirichlet Allocation (LDA). We owe this choice to the DARIAH-DE team who developed a Jupyter Notebook embedding the dariah_topics Python library for topic modeling (DARIAH-DE 2019) with MALLET (McCallum 2002–2018), a toolkit that builds on LDA. We adapted and expanded these notebooks to incorporate them into our topic modeling analysis workflow,5 which can be divided into four main parts: data evaluation, pre-processing of the data, topic modeling creation and post-processing of the results (Figure 1). As we demonstrate in this chart, individual steps of the workflow have to be repeated to optimize the results. Further on in this chapter, we will describe how we conducted these steps and what decisions were important for quality results.

Among the 25 topics of the Spectator periodicals published in French language, at least six topics stand out from a gender-specific perspective. Topics 4, 22, and 24 directly, topics 9, 18, and, 21 indirectly relate to character, behavior, and roles of women and men within the (emerging bourgeois) society in the 18^th century (see Table 3).

Topic 4 lists the various French terms for ‘marriage’ and ‘getting married’ (mariage, marier, épouser), ‘family’ (famille), ‘child’ (enfan), or ‘house’ (maison) which are terms that construct the destiny of young (!) women (fille, demoiselle) within the domestic sphere (in contrast to the public sphere which is attributed to men).11 In this private sphere, her main duty is to take tender (tendresse) care (soin) of her husband (mari) and children.

Topic 22 refers to the vocabulary used in the translation of the Female Spectator (1749–51), La Spectatrice, traduite de l’anglais (1750–51) as indicated in the bar chart with a probability of over 0.3 within this periodical (Figure 3) which is much higher in relation to other periodicals. La Spectatrice is one of the few spectatorial titles specifically directed to (bourgeois) women. This focus on the female readership also reverberates in the first term of the topic with ‘lady’ (dame). The subsequent terms used, such as ‘passion’ (passion), ‘bad’ (mauvais), ‘suitable’ (propre), ‘corresponding’ (convenir), ‘conduct’ (conduite), or ‘affection’ (affection), indicate that this topic is concerned with the behavior of women in public, especially in the company of men.

Topic 24, visualized as word cloud (Figure 4), also lists attributes associated with the ‘fair sex’ (beau sexe).12 On the one hand, a woman has to ‘please’ (plaire) through her inner beauty – expressed by terms such as ‘beautiful’ (bel), ‘beauty’ (beauté), ‘amiable’ (aimable), and ‘grace’ (grâce) – and on the other hand through her outer beauty – expressed as well by the terms ‘beautiful’ (bel) and ‘beauty’ (beauté), but also by ‘pretty’ (joli) or ‘taste’ (goût). Both inner and outer beauty are accentuated by appropriate ‘clothing’ (habit, mode), good ‘taste’ (goût), and ‘conversation practices’ (conversation) that are understood as suitable for a woman. Her ‘appearance’ (air), i.e., her outward appearance, has the highest priority here, as can be seen from the prominent position of the term in the first place, and is represented in all periodicals (see also topic 17 of the Spanish periodicals where the orientation on outward appearances manifests through terms such as moda – ‘fashion’, adornar –‘to adorn’, gustar – ‘to please’, hermoso – ‘beautiful’, hermosura – ‘beauty’).

The discourse on women within the French-language periodicals is further supported by topics 9, 18, and 21. While the first three topics mentioned above explicitly evoke terms for women (e.g., beau sexe, femme), and also use self-explaining terms alluding to their status (e.g., dame – ‘lady’, demoiselle – ‘unmarried young woman’, mère – ‘mother’) as well as gender-specific, heteronormative practices (e.g., marier, épouser – the act of getting married), the terms used in topics 9, 18, and 21 are more implicit to the extent that they only indirectly allude to the gender-specific discourse and roles of women and men in the (bourgeois) society within the Spectator periodicals.

The terms occurring in topic 9 describe virtuous behavior and practices. The gender-specific key concept of virtue (cf. Pabst 2007) stands at the very beginning of the word sequence. The following terms refer to the fact that virtue leads to (individual and collective) ‘happiness’ (bonheur). In general, 18^th century philosophers equate ‘virtue’ with ‘happiness’, for only those who lead a virtuous life can contribute to their own happiness and to the happiness of the community. Virtue is thus seen as a means to achieve the individual and collective goal of happiness (cf. Völkl 2022, 121–122).13

Moreover, as explained at the outset of this article, the concept of virtue becomes a gender-specific key concept in the course of the 18^th century insofar as not only different virtues emerge for women and men, but also considering that women have to follow a larger amount of virtuous (i.e., morally acceptable) behavioral norms than men. On the discursive level, this appears through a quantitatively higher number of terms attributed to ‘female’ behavior than those attributed to ‘male’ behavior. The reason for this is that in the 18^th century, the virtuousness of the whole (bourgeois) society becomes more and more associated with the virtuous behavior of women. In the Spectator press, precisely this virtue is constantly promoted (cf. Völkl 2022, 120-124).

Topic 9 can be found in all Spectator periodicals at a median rate of 0.62 (Figure 5) which makes it the most probable in the corpus. This is not surprising because most periodicals explicitly state their goal in their first lines which is to turn all people into useful members of the society – a society which is becoming increasingly complex and integrated into a nation (cf. Ertler 2010, 100). In terms of women as useful members of society, the role of the (bourgeois) woman is conceptualized in three ways: as spouse, housewife, and mother. Outside the domestic sphere, she has no right to exist, which is the reason why, for example, the image of the learned woman was defamed in the Spectator periodicals at the beginning of the 18^th century and has subsequently been omitted altogether – according to the motto ‘out of sight, out of mind’ (cf. Völkl 2022, 309–310).

Topic 18 results in terms referring to the virtuous ideal image of both women and men. The terms ‘tender’ (doux, tendre), ‘amiable’ (aimable), ‘grace’ (charme), ‘prudent’ (sage), ‘witty’ (brillant) here refer to inner virtues while the terms ‘beautiful’ (bel) and ‘beauty’ (beauté) can refer to inner and outer virtues at the same time as explained above. Although this is not a frequent topic, it is consistently present in all Spectator periodicals.

Topic 21 exhibits terms that can be assigned to the discourse field of love. They are associated positively or negatively with love. For example, next to the approbatives ‘to love’ (aimer), ‘happiness’ (bonheur), or ‘tender’ (tendre), one can find the pejoratives such as ‘unhappy’ (malheureux), ‘pain’ (douleur), or ‘to lose’ (perdre). The frequency of individual terms will be discussed below.

A look at the distribution of topic 21 within the French-language periodicals (Figure 6) reveals that the three successive periodicals Le Nouveau Spectateur (1758–60), Le Monde comme il est (1760), and Le Monde (1760–61) of Jean-François de Bastide (1724–1788) are particularly endowed with this topic. The literary and cultural studies research carried out by Fischer-Pernkopf et al. and Völkl support the finding that Bastide continuously narrates exemplary stories of happy and unhappy (heterosexual) lovers (cf. Fischer-Pernkopf et al. 2018, Völkl 2022).

The proximity of the nodes and the edges weight in the network analysis graph in Figure 7 also illustrates the prevalence of topic 21 in all of Bastide’s periodicals. It further shows that topics 614 and 2315 are also very common in Bastide’s periodicals. They include typical narrative vocabulary (e.g., demander – ‘to ask’, répondre – ‘to answer’, entrer – ‘to enter’, entendre – ‘to listen’, lire – ‘to read’) and typical narrative elements (e.g., ami – ‘friend’, maison – ‘house’, chambre – ‘room’, porte – ‘door’). Based on the accumulation of narrative terms, it can be concluded that in Bastide’s periodicals, the discourse of love is primarily conveyed through stories and storytelling. This interpretation of the topic modeling results is supported by previous literary and cultural research in this field which also stresses the strong narrative design of Bastide’s periodicals (cf. Fischer-Pernkopf et al. 2018, Mussner 2016, Völkl 2022).

Additionally, the analysis of the issues manually annotated with the subjects/keywords ‘Image of women’ and ‘Image of men’16 of the Nouveau Spectateur17 and the Monde comme il est 18 identified that the following five narrative forms (Erzählformen) are predominately used to discuss family life (in particular education) and couple relationships (with a focus on the romantic tender love relationship): general account (allgemeine Erzählung, AE), heteroportrait (Fremdporträt, FP), metatextuality (metatextueller Kommentar, MT), dialogue (Dialog, D) and letter/letter to the editor (Leser*innenbriefe, LB) (cf. Völkl 2022, 209). Concerning the distribution and arrangement of these text types, it has to be emphasized that they also repeatedly appear intertwined within each other which leads to the – for the Spectator periodicals – typical multi-layered system of communication (cf. Fischer 2014, 74–83).

Figure 8, which shows a statistical examination of all issues of Bastide’s periodicals, further supports the above-mentioned results. It shows that Bastide uses the following narrative forms as predominant communication strategy: metatextual commentaries (MT), letters/letters to the editor (LB), dialogues (D), and general accounts (AE). While the heteroportrait (FD) only stands on fifth position after citation/motto (ZM).

Furthermore, the three bar charts of the topic distribution in Bastide’s periodicals (Figure 9, Figure 10, and Figure 11) indicate a wide distribution of topic 9 (virtuous behavior and action) and topic 6 (describing the postulate of enlightened philosophers: ‘(Self)reflection’ (réflexion) leading to ‘truth’ (vérité) and knowledge). This focus on virtue and vice is not surprising at all, considering that the Spectator periodicals aim at the moral education of their female and male audience. The readers of the periodicals in general and of Bastide’s periodicals in particular are repeatedly exposed to vicious behavior and actions by means of shorter and longer stories in order to guide them to virtuous behavior and actions. A detailed definition or specification of the social norm designated by the term ‘virtue’, however, is lacking and thus remains undefined; rather, ‘being virtuous’ is illustrated indirectly through the depiction of its opposite: ‘being vicious’. Via the detour of numerous love and relationship stories as well as character portraits which clearly highlight vicious behavior and vicious character traits, the readers are thus led to the desired social norm (cf. Völkl 2022, 291–292).

Regarding gender-specific topics, the topic modeling results for the Spanish-language periodicals were similar to those of the French-language Spectators. Within the 18 Spanish topics, topics 8, 9, 11 and 17 can be identified as referring to women and men (see Table 4).

Topic 8 is headed by the gender-specific key concept of ‘virtue’ (virtud) followed by terms describing elements of a virtuous lifestyle (vida – ‘life’, amor/amar – ‘(to) love’, honor/honrar – ‘(to) honor’), thereby showing considerable similarities to topic 9 of the French-language periodicals.19 This topic similarity is not surprising at all since the contemporary gender discourse within the French-language periodicals enters the Spanish periodicals – that first appear in Spain from mid-century onward – through numerous translations, imitations, and cultural adaptations. Here, as in France, women and their behavior are held more responsible for the virtuousness of the whole (bourgeois) society than men. More than in other European countries, however, women in Spain are excluded from public life and confined to the private sphere which centers on home, family, and motherhood (cf. Völkl 2022, 229).20 An abundant presence of topic 8 in all Spanish periodicals is thus an expectable development (Figure 12).

Topic 9, with terms such as ‘writing’ (escribir), ‘studying’ (estudiar), and ‘reading’ (leer), alludes to educational activities; the terms ‘science’ (ciencia), ‘art’ (arte), or ‘history’ (historia) of ‘ancient’ (antiguo) time to specific study objects. The convergence of these terms suggests that this topic describes the education of a bourgeois man, even though no term referring to a male subject (such as hombre) – nor to a female subject (such as mujer) – can be found. In fact, although the Spanish periodicals grant the female gender a certain capacity for education as well, the terms of topic 9 refer to male formation only. Education for young women is conceived differently to education for young men because (as the French-language periodicals) the Spanish Spectators also propagate a complementary gender model, implying that women and men need to be educated specifically for the correct fulfillment of their gender-specific role in society. The Spanish ideal of the virtuous (bourgeois) woman is also praised in her threefold role as spouse, housewife, and mother, through the fulfillment of which she contributes to the common good of society. This image of woman is conceived in a ‘natural complementarity’ to man, whose ideal image is embodied by the ‘hombre de bien’. The latter is characterized by the training of his intellect and subsequently proving useful for his fatherland and the common good. The ‘hombre de bien’ of the 18^th century is thus not to be confused with the preceding aristocratic ‘hombre de bien’ of the 17^th century, whose idleness causes his reputation to fall below that of an active citizen – regardless of his status (cf. Heße 2008, 113–130).

Very similar to topic 4 in the French Spectators, the content of topic 11 supports the construction of the heteronormative society, suggesting the ideal role of ‘woman’ (mujer) and man in ‘marriage’ (maridar, matrimoniar) where they become ‘mother’ (madre) and ‘father’ (padre) of ‘children’ (hijo, niño). The role of the woman is thus conceived by her ‘husband’s’ (marido, esposo) side to whom she is supposed to be a good spouse and housewife. Within the domestic sphere (familia), she also receives the role of the ‘caring’ (cuidar, cariño) mother who ‘loves’ (amor, amar) and ‘raises’ (criar) her ‘children’ (hijo, niño). Although a rather infrequent topic (Figure 13), it exists throughout all Spanish Spectators.

Topic 17, represented in Figure 14, points to two discourses associated with the female gender: on the one hand the subject of beauty, on the other hand the then vicious trend of having a relationship with a younger man (cortejo). The first eight terms of this topic (mujer – ‘woman’, moda – ‘fashion’, dama – ‘lady’, gustar – ‘to please’, hermoso – ‘beautiful’, adornar – ‘to adorn’, hermosura – ‘beauty’) refer to the semantic field of beauty which pervades the spectatorial gender discourses throughout the century and clearly reflects topic 24 of the French-language periodicals (see Figure 4). In fact, the Spectator periodicals by and large constantly instruct their readers to cultivate external and, increasingly, internal beauty because female beauty is perceived as a pledge for marriage (cf. Schaufler 2002, 190) which is seen as the ‘natural’ destiny of the (bourgeois) woman and is thus considered her ultimate goal. At the same time, however, the periodicals warn against falling prey to a cult of beauty that goes hand in hand with the vices of vanity and jealousy. One of these vices, also represented in topic 17, is the gender-stereotypical model of the cortejo, i.e., a (younger) man maintaining a very close relationship with a married woman or widow who he ‘visits’ (visitar) regularly.21 While this (mostly platonic) form of relationship is not a moral offense in aristocratic tradition, it is criticized and stigmatized in the Spectator periodicals.

Regarding the dissemination of the gender-related topics, the Spanish periodicals pursue a similar strategy to their French-language precursors. Likewise, in the Spanish Spectators virtuous and vicious gender-specific values, norms and practices are mostly conveyed through stories and storytelling. Similar to the French topics 6 and 23, the topic modeling process for the Spanish Spectators revealed topics with a high concentration of narrative vocabulary, such as in topic 2.22 Therein, narrative vocabulary revolves around the semantic fields of movement (e.g., venir – ‘to come’, salir – ‘to leave’, llegar – ‘to arrive’), speech (e.g., contar – ‘to narrate’, entender – ‘to listen’, palabra – ‘word’), and time (e.g., año – ‘year’, hora – ‘hour’, noche – ‘night’), all of which are important components in a story. As can be discerned in Figure 15, topic 2 occurs in all Spanish periodicals.

With their gender-specific discourses, the Spectator press (co-)constructed, preserved, and propagated a bourgeois gender model which is still valid in socio-cultural perception today. This contribution investigates 1,658 French- and 690 Spanish-language issues which were analyzed with topic modeling using LDA. The findings with a focus on gender-specific discourse match and reinforce the results from Völkl’s study on narrative and media-specific gender construction within the Spectator periodicals (Völkl 2022).

Using topic modeling, gender-specific topics were identified in the Spectator corpus. Additionally, the application of topic modeling also showed that the Spectator press employed a certain narrative vocabulary (French Spectators: topic 6 and 23; Spanish Spectators: topic 2). Moreover, the comparison between the French- and Spanish-language periodicals rendered similar results: The Spectator corpus of both languages manifested several topics pertaining to a gender-specific discourse. This discourse can be discerned explicitly in topics which exhibit terms referring to female or male stereotypical models, or implicitly in topics which exhibit terms referring to virtuous and vicious gender-specific values, norms, and practices. The study also showed that within the gender-specific topics more terms refer to ‘female’ than to ‘male’ (character) traits and behavioral patterns. This result is not surprising neither since the Spectator press supports the creation of a (bourgeois) gender model, based on the complementarity of women and men, and in which the ‘female’ virtues are assigned a much greater importance for the stability and moral functioning of the society (cf. Pabst 2007; Steinbrügge 1987; Völkl 2022, 120-124). These concordances ascertain that topic modeling as the method used for the present analysis can be successfully employed to question and confirm hypotheses gained through close reading.

In addition to our findings on the gender-specific topics in the Spectators, we described the topic modeling workflow used in DiSpecs in section 4. We aim to make our analysis process transparent for other researchers interested in this method. The research community can also benefit from the primary data available in TEI, and the code which all are publicly available online (Ertler et al. 2011–2021, Scholger et al. 2019–2021, Scholger et al. 2022).

The DARIAH-DE Notebooks that implement LDA topic modeling proved to be very useful as a basis in our analysis workflow. With some adaptations and additional pre-processing (especially segmentation and lemmatization) and post-processing steps (e.g., results categorization and additional visualizations), we were able to produce comprehensible and insightful results. Our own experience and the comparison with other topic modeling projects allow us to conclude that pre-processing is a crucial part of the analysis since it strongly impacts the quality of the results. The decisions on the respective steps depend on the research material and the specific project goals.

An advantage of topic modeling is the possibility to analyze more content than with close reading, to illustrate the hypothesis on a broader level than through individual examples, and to present the findings using different types of visualizations. Our topic modeling analysis resulted in measurable data of a large text collection’s semantic structure which we were able to interpret and comprehensively demonstrate to the Spectators research community. Furthermore, the analysis invoked some new insights into the corpus. Concerning the gender-specific discourse in the Spectators, we saw, e.g., with topic 22 that the French translation of the Female Spectator is equipped with a specific semantic vocabulary that can almost exclusively be found in this specific periodical. This result can be attributed to the fact that in this case, we are dealing with a translation and not with a genuine French periodical.

The primary data and the digital scholarly edition also benefit from the topic modeling analysis. With the resulting topics, it is now possible to revise the keywords manually assigned to the individual issues and to further differentiate them. The list of 37 keywords was determined at the beginning of the digital edition project around 2011 and was only minimally expanded in the course of the project. Consequently, the list seems somewhat arbitrary: culture- and language-specific topics – such as ‘Apologetic of Spain’ which only apply to a few issues – are on the same level as very broad topics such as ‘Theatre, Literature, Arts’ which combine three areas in one topic. Therefore, the results from topic modeling help to expand and adjust the list of keywords for thematic indexing, thus improving the analysis capabilities within the digital edition as demonstrated in LdoD Visual by Portela and Rito Silva 2017. The identified terms in the topics can be incorporated into the TEI metadata header and subsequently used for a more precise and sophisticated search not only at the document level but also on specific text fragments.

Nevertheless, it is necessary to mention certain challenges in using topic modeling. Critics like Dobson argue that the variability of the output depending on the algorithms and set parameters of the method is problematic (cf. Dobson 2021, §20), while Roe, Gladstone, and Morrisey also refer to the probabilistic nature of LDA causing variability in individual runs even with the same parameters (cf. Roe et al. 2016, 4). While we did not compare our LDA results with other algorithms, we agree with Schöch that these variations manifest themselves “in the details of word ranks rather than in the general topics obtained” (Schöch 2017). Parameters have to be tested for individual projects, but once optimized, the method provides relatively stable results.

Furthermore, Murakami et al. as well as Shadrova are skeptical towards methods based on the bag-of-words approach because it ignores the grammatical structures and semantic relations between words (cf. Murakami et al. 2017, 246, Shadrova 2021, 13-14). While we do agree with this statement and believe that every scientific method should be questioned, we also argue that digital methods are not supposed to take on our tasks as humanities experts, but to facilitate research and help us to interpret our data. For these reasons, using a combined approach of topic modeling (and text mining methods in general) and close reading is essential as well as the understanding of the material itself. As Fechner and Weiß point out, it is not the topics that answer research questions themselves, but the researchers through the interpretations of the topics (cf. Fechner and Weiß 2017, 20).

Besides the contribution to the current state of Spectators research and to practical applications of topic modeling, our work also lays the foundations for future work on 18^th century literature. The presented results can be compared with similar research on other genres of that time. In addition to the probabilistic topic modeling approach, we intend to integrate transformer-based models to investigate a new corpus of Spanish epistolary novels which are considered to have continued propagating gender-specific values, norms, and practices from the Spectators while also representing an intermediate step towards the 19^th century novel.
