Code Search Based on Alteration Intent

open access: yesIEEE Access, 2019
Code search is to retrieve the method according to the user needs. Many people think of the query as the only one to reflect the user needs. So they start with the query and find the synonyms, semantically similar to the query terms, for query expansion.

Proximity relevance model for query expansion [PDF]

open access: yesProceedings of the 31st Annual ACM Symposium on Applied Computing, 2016
Query expansion (QE) aims at improving information retrieval effectiveness by enhancing the query formulation. Because users' queries are generally short and because of the language ambiguity, some information needs are difficult to satisfy. Query reformulation and QE methods have been developed to face this issue.

Conceptual Query Expansion [PDF]

open access: yes, 2005
Query expansion has been extensively studied as a technique for increasing information retrieval performance. However, due to the volume of documents available on the web, many of the techniques that have been successful in traditional information retrieval systems do not scale well to web information retrieval.

Query expansion and query reduction in document retrieval [PDF]

open access: yesProceedings. 15th IEEE International Conference on Tools with Artificial Intelligence, 2004
We investigate two seemingly incompatible approaches for improving document retrieval performance in the context of question answering: query expansion and query reduction. Queries are expanded by generating lexical paraphrases. Syntactic, semantic and corpus-based frequency information is used in this process.

WORD SENSE DISAMBIGUATION METHOD USING SEMANTIC SIMILARITY MEASURES AND OWA OPERATOR [PDF]

open access: yesICTACT Journal on Soft Computing, 2015
Query expansion (QE) is the process of reformulating a query to improve retrieval performance. Most of the times user's query contains ambiguous terms which adds relevant as well as irrelevant terms to the query after applying current query expansion ...
