The Centre for the Digital Research of Religion, a sub-department of the Department for the Study of Religions, Faculty of Arts, Masaryk University (https://religionistika.phil.muni.cz/cedrr) is pleased to invite you to the latest in its series of open seminars aimed at enhancing digital competencies.
Due to the current circumstances, the seminar will be delivered online.
The seminar will focus on the basics of computational text analysis. Examples will be mainly be drawn from patristic literature. As well as learning about the techniques themselves, participants will also have the opportunity to gain first-hand experience of their application.
At a time when we all find our opportunities for academic interaction limited, we believe that this seminar will be a refreshing participatory experience for all who attend.
When: Tuesday, March 31, 2020 10: 00-12: 30 and 13: 30-16: 00

Annotation:
This online workshop introduces some basic methods and tools for computational text analysis in Python and is aimed at humanities audience with very limited or no experience with programming. The workshop will consist of two 2-hours sessions full of hands-on exercises, based mainly on textual data of potential relevance for the audience (e.g. historical sources in Latin or Greek). The first session will begin slowly, enabling anyone to properly set up the working environment and run all scripts and exercises. The second session will culminate with introducing some more advanced examples of word embeddings. The workshop will cover concepts and themes such as cleaning textual data, tokenization, lemmatization, POStagging, parsing TEI-XML files, bag-of-words model, word co-occurrences, the distributional hypothesis of meaning and word embeddings. The workshop does not require installing any special software, the only technical requirements are an internet connection, a web browser, and a Google account.
