Research on information retrieval model based on ontology

Whether it’s a document management system or a laboratory information management system, some sort of query function is involved to help the user find specific documents or data. How that data is retrieved—using information retrieval methods—can vary, however. In this 2019 paper published in EURASIP Journal on Wireless Communications and Networking, Binbin Yu details a modified information retrieval methodology that uses a domain-ontology-based approach that integrates document processing and retrieval aspects of the query. Domain ontology takes into account semantic information and keywords, which improves recall and precision of results. After explaining the mathematics and experimentation methodology, Yu concludes “the genetic algorithm shortens the distance compared with simulated annealing, and the ontology retrieval model exhibits a better precision and recall rate to understand the users’ requirements.”
