TYPE OF EXPANSION
Automatic query reformulation
query expansion
<information science> Adding search terms to a user's
search. Query expansion is the process of a search engine
adding search terms to a user's weighted search. The
intent is to improve precision and/or recall. The
additional terms may be taken from a thesaurus. For example
a search for "car" may be expanded to: car cars auto autos
automobile automobiles.
The additional terms may also be taken from documents
that the user has specified as being relevant; this is the
basis for the "more like this" feature of some search engines.
The extra terms can have positive or negative weights.

Query expansion
Query expansion (QE) is the process of reformulating a given query to improve retrieval performance in information retrieval operations, particularly in the context of query understanding. In the context of search engines, query expansion involves evaluating a user's input (what words were typed into the search query area, and sometimes other types of data) and expanding the search query to match additional documents. Query expansion involves techniques such as:
- Finding synonyms of words, and searching for the synonyms as well
- Finding semantically related words (e.g. antonyms, meronyms, hyponyms, hypernyms)
- Finding all the various morphological forms of words by stemming each word in the search query
- Fixing spelling errors and automatically searching for the corrected form or suggesting it in the results
- Re-weighting the terms in the original query
Query expansion is a methodology studied in the field of computer science, particularly within the realm of natural language processing and information retrieval.
