Andreas Niekler is a research associate at the Institute of Computer Science at the University of Leipzig. He develops computational methods in the area of semantic properties of language, as well as computational algorithmic methods for Computational Social Science and Computational Humanities. The focus is on machine learning and data management methods. Basic principles of empirical research play a major role in his work.
He is involved in the development of the interactive Leipzig Corpus Miner and is currently researching how semantic representations of text can be used for literary and scientometric questions. Furthermore, he conducts research on political science topics and contributes his experience in automatic content analysis to this field of research.
In teaching, he lectures on computational humanities and computational linguistics methods and gives courses in R and Python.
Research Interests: Natural Language Processing and Text Data in Computational Social Science / Digital Humanities, Conversational AI, Automated Content Analysis, Topic Analysis, Contextual and semantic dynamics in text data, Text Mining, Data Science, Information Extraction, Process and Activity Extraction from Text Data, Computational Linguistics, Transfer Research, Machine Learning, Internet Technologies, Information Systems, Visualization, Media Informatics, Communication Research.
Algorithms and methods: Bayesian models, maximum entropy models, topic models, support vector machines, deep learning, language models, association rule mining, minimum hashing, decision trees, conditional random fields, visualization.

Within the scope of my previous activities, I have designed my own teaching content, supervised and organized seminars in the field of digital humanities and social sciences and computer science. I would like to emphasize my commitment and skills in methodological training. For several years, I have regularly taught applied introductory courses in text mining and machine learning in the social and communication sciences. I have already taught in the areas of basic computer science (algorithms and data structures, modeling and programming) and in applied topics (text mining, linguistic computer science) at the University of Leipzig. I am fluent in the necessary basics of mathematics, computer science and didactics, I regularly participate in the advanced trainings of the Hochschuldidaktisches Zentrum Sachsen and I can use these competences in teaching.
