synonym(s): Syntactic Analysis
definition: Parsing (=syntactic analysis) of natural language utterances is still an active reasearch topic due to the inherent difficulties that make the problem much harder than e.g. parsing of programming languages. These difficulties include lexical and structural ambiguity of natural language utterances, complexities introduced by expressive grammar formalisms, the need to cope with illformed input or with deficiencies of the linguistic descriptions.
