Entering a Concept Search
Concept expansion is turned off by default within Texis. To expand the meaning
of a word or phrase within your query, precede it with a '~' (tilde)
character.
Metamorph and Texis have an edit-able vocabulary of over 250,000 word and
phrase associations. Each entry is generally classifiable by either its
meaning or part of speech.
The general theory behind our concept search is that in any communication
the exact choice of word usage may vary between authors, but the underlying
meaning is carried by overlapping domains of commonly shared vocabulary.
To compensate for the differing vocabulary between an author and a searcher
of a document our software looks for all of the possible combinations
of intersecting meanings that are present in the search request.
A good example of this is the intersection of bear and arms .
Individually the words have a greatly diverse set of meanings, but together
they have only the "carrying weapons" meaning.
