Medical Query Expansion using UMLS

Internet users have grown in recent years and they demand answers for many through online. Searching and retrieving documents is one of the most frequent thing most of the people do today. For retrieving medical related documents, we have to be extra careful and precise in the process of retrieval. Even though separate search engines are there to retrieve medical documents with care, the users are not well-known with MeSH terms (Medical Subject Heading). MeSH terms are terms used by medical professionals to retrieve documents. So the query has to be framed in such a way that only correct documents should be produced to the user. In this work, we proposed a method that deals with enriching the user query with the use of UMLS. The enriched user query after expansion is used to get accurate documents with less amount of time.
