Synonyms, Hyponyms, and Hypernyms
You can use QMS to expand queries to include other terms that are synonymous with the other query terms.
The synonym QMS rules allow you to determine a set of keyword terms that the rule applies to, and then to specify how QMS must expand the query. For example, you can use the following types of rules:
- Synonym rule. Include the original query term and add a list of synonymous terms. For example, you could expand a query for dog to a query for dog OR hound OR canine.
- Hyponym rule. Exclude the original query term, and replace it with a list of terms that are hyponyms of this term (that is, the original term could describe all the new terms). For example, you could replace a query for dog with a query for poodle OR retriever OR labrador and so on.
- Hypernym rule. Exclude the original query term, and replace it with a single term that is the hypernym of this term (that is, the new term could describe the original term). For example, you could replace a query for poodle with a query for dog.
