Andreas Niekler is a research associate at the Institute of Computer Science at the University of Leipzig. He develops computer-based methods in the field of semantic properties in language and language-based AI. He develops computer-based algorithmic methods for computational social science , including for the research project "Postdemocracy and Neoliberalism" and for the interactive analysis platform Leipzig Corpus Miner (iLCM). The focus is on machine learning methods and data management. In recent contributions he supported various companies in Saxony adopting certain AI technologies in their daily activities. This includes processing of unstructured data for knowledge management and document management.

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.
