Contextual Phrase Information Content Analyzer

The Contextual Phrase Information Content Analyzer (CPICA) is inserted between the user query input phase and the query analysis phase in a conversational input data retrieval system. The CPICA filters out textual words that contain no contextual information content so as to improve the effectiveness of the Query Analysis Phase. The CPICA consists of a DO-LOOP where the user input is parsed and analyzed:
Enter
Do until end of user input query Get next word

Search Single Word No Information Content List

If word found in SWNIC List, then

Discard the useless word

Else

Search Phrase No Information Content List

If word starts PNIC List entry then

If rest of PNIC List phrase in user input, then

Discard the useless phrase

Endif

Endif

Endif

If word was not discarded, then

Pass word to Query Analysis Phase

Endif

Enddo
Leave

The user provides lists of words and phrases, such as conjunctions, prepositions, etc., that function as sentence "fillers" but have no information retrieval content.
