Operations on terms

IR Expert enforces term operations on all queries run on the ITSMA Service Management database, enabling automatic indexing based on key terms. These include:

Lexical analysis
The process of converting an input stream of characters into a stream of words or tokens.
Stemming
The process of combining related words, based on the reduction of words to their common root, stem, or form.
Stop words
A list of words determined to have no indexing value, used to eliminate potential terms appearing in query statements. If a word from the stop list appears in a query, IR Expert ignores that word in the search.
Spelling correction
The automated process of verifying and correcting the spelling of query terms.
