Forensics experts from Fraunhofer SIT teach methods of digital text data analysis, with a focus on computational linguistics (NLP) and machine learning (ML). This is because a large part of the information available worldwide is in texts. Crawling and then "mining" for relevant information in text is important for many applications. Recognizing the topics, "moods" or the writing style of an author is significant for forensic investigations of text files or chat histories on data carriers, or for evaluating news, company data, social media channels or opinion polls, among other things.
