Information Extraction from Texts and Text Classification

Natural Language Processing (NLP) is part of many applications, especially in text mining and there especially for the tasks of automated information extraction and tagging, automated question answering, and text summerization, but also far beyond to e.g. the design of more comfortable user interfaces as well as automated translation of texts into other languages.
