SIG DLS endorses Metaphor Workshop at International Conference of Association for Researching and Applying Metaphor in June 2020

We are delighted to point all scholars interested in metaphor analysis to the Pre-Conference Workshop “Finally, a Tool! Introducing CATMA for Identification and Metaphor Analysis with MIPVU” taking place on 18 June 2020 as part of the International Conference of the Association for Researching and Applying Metaphor (RaAM) at Hamar, Norway.


Information about the workshop

When researching real-world contexts, scholars need a valid procedure for identifying and analyzing metaphorically used language. This means that they need a handle for systematically gauging the reliability of annotations, possibly for ensuing machine learning, but also a way of spotting patterns and principles behind creative and otherwise ‘messy’ cases. One such procedure for metaphor identification is MIPVU, the Metaphor Identification Procedure Vrije Universiteit (Steen et al. 2010), which celebrates its tenth anniversary in 2020. Originally developed at VU Amsterdam, it is now being widely used in research projects around the globe, being adapted for different languages (see Nacey et al. [in press] Metaphor identification in multiple languages: MIPVU around the world) and different types of authentic data, including spoken and multimodal discourse (see VISMIP for visual metaphor [Sorm & Steen 2018], and FILMIP for filmic metaphor [Bort-Mir 2019]. However, many scholars are challenged by developing their own computational environment for applying MIPVU and analyzing the annotations, including reliability tests. Some use an XML editor, others MS Excel or MS Word. So far, a tool is missing that facilitates an intuitive annotation and analysis environment.

Our hands-on tutorial introduces metaphor scholars to a computational tool for applying MIPVU called CATMA, which stands for Computer Assisted Text Markup and Analysis, see CATMA was developed at the Hamburg University and is currently used by over 60 research projects worldwide. It supports collaborative annotation and analysis as well as explorative, non-deterministic practices of text annotation. It integrates text annotation, text analysis, and visualization in a web-based working environment, combining the identification of textual phenomena with their investigation in a seamless, iterative fashion. The workshop is endorsed by the Special Interest Group “Digital Literary Stylistics” (SIG-DLS; of The Alliance of Digital Humanities Organizations (ADHO).

Workshop format: The workshop will be hands-on. After a short run-through of the basics of MIPVU, participants will learn how to work with CATMA. This introduction to CATMA includes the core annotation and analysis functionalities, text upload, annotation and specification of annotation categories, as well as text queries of source text and its annotations. Participants will also generate the visual output of query results and learn the export of markup data in XML format. In a last section, we will discuss several methods of annotation validation, including inter-annotator agreement.

Participants will be asked to acquaint themselves with the English version of the annotation manual MIPVU in preparation. Access to language-specific MIPVU protocols from Nacey et al. (in press) may be provided upon request. Participants will, however, need no prior knowledge of computational text annotation and can work with their own laptop computers. CATMA runs on Laptop or PC (Windows, Unix or MacOS) with a current web browser (MS Explorer or Edge; Firefox, Chrome, Safari) with a mouse or touchpad (touchscreen navigation is not yet supported).

Stylometry workshop in Amsterdam 2019

It has become a tradition for the stylometric community to organize a small get-together whenever a DH conference takes place near one of the labs. In 2014 the crowd had its meeting in the Australian wilderness of Wollombi near Newcastle, and in 2016 they enjoyed the mountain seclusion of Żabnica near Kraków. This year we met in the heart of the urban jungle, at Netherlands Institute for Advanced Study in the Humanities and Social Sciences (NIAS), invited by the Riddle of Literary Quality team and Karina van Dalen-Oskam.

The meeting gathered some of the experts in the field and newcomers both from affiliated Federation of Stylometry Labs and ones pursuing solo stylometric projects. The workshop served as a great opportunity to get to know each other in a more relaxed setting and as an occasion for community building. Over the course of three days (15-17 July) we discussed our projects in development, good practices in the field and making it more accessible to newcomers, juggled ideas and enjoyed each other’s company over lovely dinners.
In relation to recent replication debates, we discussed the need for registering experimental setups as well as the exact shape of data (e.g. which particular editions were used, and what changes, such as normalization, introduced). While we noted the need for specifying the experimental setup in detail in advance, it was also observed that in practice we cannot foresee all the problems on our way and may need to adapt the method in the process.

We also discussed technical problems with working on digitized texts, especially historical ones – dealing with issues related to versioning, accuracy of preserved copies and search for the version closest to original intended by the author, lack of proper descriptions of digitized files in some collections – and the need for separating the development of reliable methods from answering actual research questions with a particular dataset.

Our interest was also sparked by a few more literary problems: the distinctiveness of authorial voice across various media (literary vs non-literary text, literature reviews, speech, audiovisual data) and manner of creating (e.g. typing oneself or dictating). Introducing the dimension of reader reception of literary texts to the discussion, researchers from Amsterdam addressed differences between stylometrists and readers in their perception of ‘style’, as well as the topic of stylistic development over time as observed in genetic criticism projects.
Finally, we also discussed the development of the Federation of Stylometry Labs and explored ideas for making it a more useful resource for aspiring stylometrists. You will notice the results of this discussion on our website in the upcoming months. This is surely of interest to SIG DLS members and observants, so stay tuned!

Digital Literary Stylistics in Utrecht: A Report on the DH2019 Conference

Most of us are back from the post-conference summer break: Time to revisit! Seven weeks have passed since the DH2019 conference in Utrecht: presented as the biggest DH conference so far (with about 1,100 participants and more than 400 presented papers), it also distinguished itself for the number and quality of contributions in digital literary stylistics. With this post, through highlights and summaries, we try to provide an overview of the most recent outcomes of stylistics research in DH. Well aware that (as our colleague José Calvo Tello already highlighted when reporting on DHd2018) these notes cannot be considered but a preliminary, incomplete, and subjective report on a much more complex and stratified event. As usual, more information can be found in the conference programme and book of abstracts, both available on the conference website. To extend the variety of documentation, then, the #dh2019 and #sig_dls hashtags were remarkably active on Twitter, while participants like Geoffrey Rockwell even shared their conference notes online.

But well, if you would like to know the specific point of view of the SIG-DLS (and, more specifically, of the member who’s writing this report), here are a few notes.

The first step, inevitably, is the pre-conference workshop organized by the SIG-DLS steering committee. Held on the morning of 9 July, DLS Tool Criticism. An Anatomy of Use Cases was conceived as a moment of self-reflection (and of self-criticism) on the tools and methodologies most frequently used in digital literary stylistics. During the workshop, Clémence Jacquot presented her use of the TXM software in the study of Apollinaire’s poetry (stimulating a discussion on limits and potentials of pre-compiled, user-friendly tools for the study of style); Geoffrey Rockwell presented a case study and a theoretical reflection on the concept of replication (thus rekindling the still lively discussion sparked by Nan Da’s criticism, but going beyond, querying ‘replication’ as a more flexible concept); and Steffen Pielström resisted the temptation to advertise his efficient topic modeling tool, inciting on the contrary an acute disputation on the pros and cons (and on the aleas) of such a technique. One of the major achievements in the final discussion was the shared impression that the quantitative/qualitative dichotomy is simply misleading, and digital literary stylistics will have to move beyond it, looking for a more organic integration of approaches.

When reaching the bulk of the conference, the impressions we can record here become inevitably more random and scattered. A general trend was evident, however, with digital stylistics contributions divided roughly in two main categories: methodological analyses, providing very advanced and stimulating discussions of (more or less) shared approaches; and applications on complex and engaging case studies. This can be considered as a reflection of the state of things in stylometry, where methodological research is needed to ground more and more steadily the scientific rigor of the approaches (with the risk of an excessive technicism), and new applications even more so, if our research field is to gain  recognition beyond the boundaries of DH.

Among the methodological papers, some titles call for a specific mention. In “Comparing Assonance and Consonance for Authorship Attribution”, Lubomir Ivanov proposed prosodic elements as possible new features in stylometric classification, considering the extremely relevant role of prosody in 18th century prose (and beyond). His experiments showed how the combination of assonance/consonance with traditional stylometric methods generates significant improvements in the classification. Further research on the subject is definitely advised! In “Feature Selection in Authorship Attribution: Ordering the Wordlist”, Maciej Eder and Joanna Byszuk worked on the effects of re-ordering the (traditional) list of features. Main discovery: a combination of term frequency (the widely-used MFW) and a coefficient of variation slightly improves the results. Finally, in “Identifying Similarities in Text Analysis: Hierarchical Clustering (Linkage) versus Network Clustering (Community Detection)”, a team of four researchers led by Jeremi Ochab tried to provide an answer to a still under-studied–but ever-present–question in stylometric classification: how do I cluster the texts to visualize similarity/dissimilarity? Results showed that network clustering tends to underestimate the actual number of clusters, while hierarchical clustering overestimates it (and of course, which one is better will depend on the research question!). Traditional algorithms (Ward, Louvain) were confirmed as the most efficient.

Placing itself between method and application, David L. Hoover proposed his “Invisible Translator Revisited”. Given the (supposed) invisibility of the translator in stylometry, Hoover proposed a method for making her visible again, by filtering out the words preferred by the author. The approach showed surprisingly effective, but will it work for all pairs of authors-translators? As it happens, the idea found an indirect confirmation in “Attributions Of Early German Shakespeare Translations”, where a team of three researchers led by David Lassner was equally successful in revealing the translator (here, by combining advanced classification methods based on sub-word-level features). Shifting the focus towards themes and genres, Fotis Jannidis and his colleagues (in “Thematic complexity”) used two approaches, LDA and Zeta, to model genre distribution and to measure thematic complexity (via the “Gini index”) for dime novels and high-brow genres. Their results support their hypothesis of high literature comprising a broader spectrum of subject areas than pulp fiction genres. On a similar line of enquiry, a team of seven researchers led by J.D. Porter used stylometric approaches to identify passages in novels that adopt stylistic traits from other genres (in the paper “Microgenres”).

Moving then to the applications, it is worth mentioning “Challenging Stylometry: The Authorship of the Baroque Play La Segunda Celestina”, by Laura Hernández Lorenzo and Joanna Byszuk (who wins our award of the most prolific stylometrician, with three co-authored papers, and who on top of that also has contributed a SIG-DLS blog post!). That of La Segunda Celestina is a real “challenge” for authorship attribution: in fact, the results of the analysis did not limit themselves to “solving” the problem, but suggested possible new lines of enquiry. In “Stylometric Analyses of Character Speeches in French Plays”, then, Ioana Galleron provided an effective example of “scalable reading”, combining multiple approaches to distinguish the style of male and female characters. Finally, Massimo Salgaro and Simone Rebora (i.e. myself, in the panel “Digital Humanities for the Study of Social Reading”) showed how stylometric approaches can also be used to distinguish professional and non-professional book reviews.

A conclusive note should be dedicated to “Stylometry for Noisy Medieval Data: Evaluating Paul Meyer’s Hagiographic Hypothesis” by Ariane Pinche, Jean-Baptiste Camps, and Thibault Clérice. The work stands out as a perfect realization of a processing pipeline (from handwritten text recognition to stylometric classification, with advanced techniques to reduce noise and manage spelling variants) that instantiates a fruitful dialogue with traditional literary research, by confirming (and in part disputing) Paul Meyer’s hypotheses about the composition of the French saint’s Lives. The paper was awarded the Paul Fortier Prize for the best young scholar paper of the conference. A further success that confirms the increasingly central position of digital literary stylistics in DH research.

The SIG-DLS steering committee reiterates their congratulations to Ariane, Jean-Baptiste, and Thibault, but also to the Programme Committee chairs Elena and Fabio, and to the local organizers Joris and Franciska, for making such a spectacular conference possible. Looking forward to meeting you all again in Ottawa (hopefully, with even more stylometry to discuss)!
