Abstract: Nowadays, the internet is the major source of information for millions of people. There are many search tools available on the net but finding appropriate text information is still difficult. The retrieval efficiency of the presently used systems cannot be significantly improved: |bag of words| interpretation causes losing semantics of texts. We applied the functional approach to represent English text documents. It allows taking into account semantic relations between words when indexing documents and use ordinary English sentences as queries to a search engine. The proposed retrieval mechanisms return only highly relevant documents. They make it possible to generate content-aware summaries on-the-fly. The presented examples illustrate the advantage of the discussed approach compared to the traditional key word search.

Keywords: semantic search; ontology; indicative summary; semantic retrieval; document represention; information retrieval; document summarising; text documents; English sentences; search engines; content-aware summaries.
