Requirement analysis of the internal modules of natural language processing engines

This paper describesr the modules of natural language processing (NLP) engine which can be used with Hungarian input. There are many standard NLP engines which have tokenization, part-of-speech (POS) tagging, named entity recognition, parsing modules. Most of them work for universal languages like English. Processing of Hungarian language is a much more difficult and there cannot be found such a complete NLP system which satisfies all tasks for syntactic and semantic analysis of incoming inputs. This paper summarizes the existing solutions and techniques and gives a brief description of a proposed NLP engine using for inputs in Hungarian language.
