Abstract: 

Synonym features in the Lexical Tools are used as element synonyms for subterm substitution in query expansion to improve recall in concept mapping in various NLP projects, such as UMLS-CORE, Sophia, STMT, MMTx. This paper describes the implementation and evaluation of enhanced synonym features in the Lexical Tools (2017). The results show an improvement (~5%) on both recall and F1 with similar precision using enhanced synonym features in query expansion for UMLS concept mapping.
