National Information Processing Institute

Natural Language Processing Laboratory

Natural Language Processing Laboratory creates tools that help discovering knowledge form textual data. The tools are extracting, processing and analysing information that is stored in text in natural language.

Natural Language Processing Laboratory fulfills assignments connected with natural language processing and text/web mining. Particular emphasis is put on semantic analysis of texts, information retrieval and recommendation engines. The part of conducted work is also connected with multicriterial optimization problems using genetic algorithms. Creating the prototypes of tools is the results of all research.

The majority of prototypes we build is implemented in the industry in the form of modules or entire systems. We build dedicated tools for government agencies (e.g. National Centre for Research and Development) and for commercial customers (e.g. Millward Brown).
