Segmentation Expansion Algorithm for Keyword-Aware Optimal Route Query [PDF]
Jisuanji gongcheng, 2022 The Keyword-aware Optimal Route query(KOR) obtains the route with minimum time overhead under the conditions of full keyword coverage and path length constraints;it is commonly used in travel planning.Although existing optimization algorithms use various

Translating queries into snippets for improved query expansion [PDF]
Proceedings of the 22nd International Conference on Computational Linguistics - COLING '08, 2008 User logs of search engines have recently been applied successfully to improve various aspects of web search quality. In this paper, we will apply pairs of user queries and snippets of clicked results to train a machine translation model to bridge the "lexical gap" between query and document space.

Query expansion and query reduction in document retrieval [PDF]
Proceedings. 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.

Event-Driven Query Expansion [PDF]
Proceedings of the 14th ACM International Conference on Web Search and Data Mining, 2021 A significant number of event-related queries are issued in Web search. In this paper, we seek to improve retrieval performance by leveraging events and specifically target the classic task of query expansion. We propose a method to expand an event-related query by first detecting the events related to it.

Code Search Based on Alteration Intent
IEEE 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.

Applying Biomedical Ontologies on Semantic Query Expansion [PDF]
, 2009 *1- Introduction* The interpretation of a question (or information need) depends, among other things, of a series of lexicalsemantic relations that complement and help the cognitive process of answering that information need.
