SIG-DLS endorses workshop at DHLab Basel, Switzerland

We are delighted to announce a new SiG-DLS-endorsed event!

On 8 and 9 November, 2018, the Digital Humanities Lab Basel (Switzerland) will host an Intensive Training «Finding Metaphor in Discourse» endorsed by SIG-DLS.

The event is co-endorsed by the International Association for Researching and Applying Metaphor (RaAM).

It features annotation tutorials on manual Metaphor Identification (MIPVU), a vector-based exploration by Nils Reiter and his team from Stuttgart, and the annotation and corpus tool CATMA. The workshop is a 1.5-day event.

In addition there’s going to be two full lectures by Lettie Dorst (Leiden) and Jan-Christoph Meister (Hamburg), which may be attended independently of the workshop.

Register soon as places are limited!

Attendence is free of charge.

MA Seminar in Stylometry @ Uniwersytet Jagielloński, Kraków, Poland

This is a two-year course taught (or, rather, loosely coordinated by Jan Rybicki), which introduces students of the University’s Translation Studies programme to quantitative approaches in the study of – you’ve guessed it – translation. The course’s main deliverable is a ca. 80-page dissertation in English.

The course’s first year begins with an introduction to the field and to its methods, and ends in a specified subject of later work. The students also produce a short “teaser” of what they will be writing about. Some examples are presented below.

Genres according to Project Gutenberg

The subject of this experiment is 83 novels that, according to the Project Gutenberg, belong to one of the three genres: adventure, crime fiction and detective fiction. The presented samples are both originally written in English and translated into English, for example from French (such as Jules Verne, Alexander Dumas père). The majority of the selected authors appear only in one category; however, there are three names (Morrison, Orczy and Wallace) that have works that belong to both adventure and detective fiction; thus, to those books that belong to adventure section, a letter A has been added after the name of the author. Moreover, the name Stevenson appears in adventure as well as detective fiction; yet the name does not represent the same person. Adventure is represented by Robert Louis Stevenson and detective fiction by Burton Egbert Stevenson. In order to avoid confusion, the letter B has been added to the latter man’s work.

The aim of the experiment is to determine whether the novels that Gutenberg categorised into one group can be distinguished from those belonging to two other groups. Furthermore, it ought to be established whether translations from the same language show any similar traits. Another issue that is of concern is the matter of authorial signal, for there are novels written by the same author that belong to two categories. The methods employed to answer all those questions are consensus cluster analysis (Figure 1) and network analysis (Figure 2).

Figure 1. Cluster analysis

Cluster analysis illustrates the relationship between particular samples; however, if one was to see connections between all the texts, network analysis is needed.

Figure 2. Network analysis

In order to distinguish what category does a particular novel belong to, the sample has been coloured according to their category: red shades for adventure, green shades for crime fiction and blue shades for detective fiction.

The adventure books appear to exhibit similarities between one another, as the samples are grouped closely together. The only novel that is separated from the rest is Arthur Morrison’s  The Dorrington Deed-Box (morrisonA_box). It is instead grouped with other Morrison’s books, those that belong to the detective fiction category, thus showing a strong authorial signal of Morrison. Detective fiction novels, though not as neatly as the adventure ones, are mostly grouped in one place. They are more interconnected with crime fiction novels, which illustrates the similarity between the two categories. Authors that are particularly close include Sax Rohmer and Arthur Rees or Joseph Smith Fletcher, Harrington Strong and H. Beam Piper. Crime fiction novels do not seem to compose a strong group, as only a few samples are present in a particular place on the network. As previously stated, this category is interlaced with detective fiction novels.

Translated samples do not show any apparent similarities, as they are not universally connected one to another or even placed in close proximity on the network.

Taking all the evidence into consideration, it can be concluded that the Gutenberg division proves to have some merit. Adventure books clearly compose one group. Detective and, particularly, crime fiction are not clustered so closely but, as they are genres similar enough, the connection between them can be expected.

Discovering The Dirty Old Man’s Identity

My very first research that I did more for fun than on spec for a serious discovery turned out to be more fascinating than I thought of. It all started after 1834 when Adam Mickiewicz, one of the most important figures in Polish literature, wrote an epic poem considered the national epic of Poland, Pan Tadeusz  (Sir Thaddeus). The poem consists of twelve chapters called books, all written in Polish alexandrine (13 syllables divided into two half lines). There is, however, yet one chapter called the 13th Book that describes the wedding night of the title character Tadeusz with Zosia. The book resembles Mickiewicz’ style in its use of the Polish Alexandrine but on the other hand is packed with words that are commonly treated as vulgar. There was ongoing speculation about the authorship of the 13th Book of Pan Tadeusz as no writer owned up to writing it. There were three authors who were taken into account: Tadeusz Boy-Żeleński, Włodzimierz Zagórski and Alexander Fredro; the latter being most frequently suspected.

In my research I decided to have a first look at the romantic writers contemporary to Mickiewicz and do a cluster analysis of their works based on 100 most frequent words. My corpus consists of 5 books of Mickiewicz (one being a translation of Byron’s The Giaur), 4 books of Fredro (with the assumption that he was the author of the 13th Book), 2 of Słowacki and 1 of Krasicki.

I expected the 13th Book to occur somewhere near Pan Tadeusz as both of them were written in Polish alexandrine as epic poems. The results however proved me wrong and rewarded me with a very satisfying discovery.

 

Figure 1. Fredro exposed

In Table 1 we can see the results of cluster analysis based on 100 most frequent words with the use of Classic Delta distance. We can clearly see that the 13th Book is closer to Fredro’s works than Mickiewicz ones. It might have been an insufficient evidence for Fredro’s authorship and that’s what I thought at first too. From all the books that my corpus consists of,  only 3 are dramas and the 13th Book seems to like them more than other, more even than Mickiewicz model Pan Tadeusz. What’s more, all of dramas included in the corpus were written by Fredro. I decided that a consensus tree based on 100-1000 most frequent words will resolve all my remaining doubts on who the title dirty old man was.

Figure 2. It’s definitely Fredro

When I saw the results of the consensus tree that is presented in the Table 2, all of my remaining doubts vaporised like a wispy Cretan cloud on my honeymoon that I send you my warm regards from.  The 13th Book still is sticks to Fredro’s dramas and is none like other epic poems from the corpus.

There is only one conclusion that I drew from my research. The resemblance that the 13th Book and Fredro’s dramas have is so apparent that we can assume that he really was the author of the filthy continuation of Mickiewicz’ national epic.

Computer Assisted Text Markup and Analysis (CATMA) – An undogmatic approach to corpus analysis and Germany’s literary super heroes

Do you know CATMA? Not yet? Then read the following blog. Do you think you know CATMA? It’s still a good idea to read the following blog…

CATMA is a web-application for text markup and analysis. Its central function is annotating, analyzing and visualizing one or multiple texts. CATMA has been around since 2008.

When the implementation of the web-application CATMA started in 2008, the focus was to create a tool for digital close reading. Although there always has been the possibility to run some standard queries as e.g. word frequencies automatically, the focus of the application was entirely on the annotation functionality of single texts. Ten years later, CATMA provides the possibility to store, manage and analyse not only single texts, but also bigger corpora – using both close and distant reading methods. Although CATMA still can be used for manual annotation of single texts, in this article, we want to show you how the web-application can be used on corpora.

Goethe and Schiller, Germany’s literary super heroes

Let’s say you would like to explore the authorial styles of Germany’s literary super heroes, Goethe and Schiller. As you want to make the two author corpora comparable, you choose 12 dramatic and 5 prosaic texts of each author. Just upload those texts to CATMA and organise them into different corpora, one with texts by Goethe and one with texts by Schiller. Once your corpora have been created in CATMA, you can easily export them, or, more important, share them with your team.

Without any further preparation you can now start analysing your corpora. Using the Analyze modul you can generate a word list with frequencies. This list will show you that there are around 800.837 words in your selection of Goethe’s texts with around 46.840 types. Schiller’s texts contain 35.351 word types and a total of 498.790 words. These numbers are not very meaningful yet, because, obviously, the texts do not have the same length. Looking at the word frequency list, from a narrative perspective, the first person pronoun “ich” (I) is probably most interesting as it points to a predominant first-person perspective. Or is it just the dramatic characters? Other highly frequent (but narratologically possibly less relevant) words in the Goethe corpus are “und” (and), “die” (the/who/which – female), “zu” (to), and “der” (the/who/which – male), much as in the Schiller corpus (albeit in the order “der”, “und”, and “die”). At this top tier of frequency, there seems to be a similarity.

Word frequencies in Goethe’s and Schiller’s texts

But how about the other end of the lexical spectrum? Goethe is known to have had a comparably large vocabulary, so we may quickly check the least frequent words in the corpus – those which are used only once. Are there many of these hapax legomena?

In the Goethe corpus they sum up to 28.792 words altogether. Schiller uses 21.025 words only once in the entire corpus. This means that Goethe uses 61.4% of all the types of this corpus only once. Schiller uses 59.4% of all types in the corpus only once. Maybe this similarity suggests that Schiller after all was closely following Goethe in variability of word use. However, nobody will ever know how large the vocabulary of Schiller’s works might have become had he reached the same old age as Goethe in the end…

If we turn away from the low frequencies now and have another look at the high ones, we get hold of another interesting phenomenon. Among the most frequently used signs by Schiller are question- and exclamation marks. They appear at ranks 4 (exclamation mark) and 8 (question mark). In the Goethe corpus they only make it to ranks 11 (exclamation mark) and 27 (question mark). A look at the distribution of exclamation and question marks in our corpora shows that the distribution of exclamation marks ist always higher than the one of question marks in the Goethe corpus. Schiller on the other side has written five texts in which there are more question marks than exclamation marks. Is it maybe that Schiller’s authorial signature is characterized by an unusual amount of questions? Especially his play “Don Carlos. Infant von Spanien” is characterized by question marks, as you can see in the CATMA small multiples view below:

Small multiples view of distributions of question- and exclamation marks in the works of Schiller

Our case study so far has applied some handy distant reading functions, which are often used in one way or another in stylistics. But CATMA offers also a method for what we call scalable reading. Starting off with distant reading as we did, you may now scale down a bit: Simple double clicking on one point in the distribution graph or one keyword in the keyword in context table will take you to the specific position in the text where you find either the keyword or the accumulation of a word or tag you found in your small multiple distribution graphs. So, you can go from corpus to multiple texts in one visualization, on to single text view and even to the very position at which you find one word in one text – changing dynamically from distant to close reading and back just as you wish. This scalability also allows to develop different kinds of interpretation from data analysis to more context-oriented interpretation of certain passages in single texts.

I leave you here to start your own case study now, be it on the style of Goethe and Schiller or other literary phenomena. But just before you do that, do know that there are more functions for working on corpora in CATMA, among which are automatic annotations of part of speech (POS) tagging, as well as that of verbal tense and temporal signals (in German texts).

And of course you can also use the central CATMA function, which is annotating one text, or a whole corpus, with your very own categories, analyzing and visualizing them. CATMA ist running as version 5.0 right now, but in 2019, CATMA 6.0 will be launched. Users can look forward to the new design of the graphical user interface, the optimization of workflows and the addition of some features. 

As we focused on the corpus-specific functions in CATMA in this article, you might want to have a look at our tutorials for a complete overview of the application’s functionalities: http://catma.de/documentation/tutorials/

Have fun annotating, exploring, and scaling!
