Natural language is what we use as an everyday means of communication among humans. It has a syntax and complies with principles of economy and optimality.

One of the biggest challenges in computer science is the creation of computers which are able to understand natural language. For that purpose, there is a whole field within computer science concerned with the interactions between computers and human (natural) languages: Natural Language Processing (NLP).

Thanks to the use of NLP techniques within the field of information searches, natural language searches, such as those provided by INBENTA Semantic Search Engine, have been achieved, which allow users to present their searches as questions or statements instead of restricting them to mere keywords.
