Effects of Porting Essie Tokenization and Normalization to Solr.

Area of Science:

• Biomedical Informatics
• Information Retrieval
• Computer Science

Background:

• Effective information retrieval is crucial in healthcare, with search engines playing a vital role.
• The National Library of Medicine's Essie search engine excelled at biomedical text retrieval but is no longer supported.
• Solr, an open-source enterprise search engine, offers continuous development and advanced features.

Purpose of the Study:

• To port key functionalities of the Essie search engine to the Solr platform.
• To develop custom components for Solr to enhance biomedical literature search capabilities.
• To provide the research community with improved tools for biomedical text retrieval.

Main Methods:

• Porting core features from the Essie system.
• Developing and integrating custom components into the Solr search engine.
• Evaluating the performance of the enhanced Solr system on benchmark biomedical datasets.

Main Results:

• Successfully ported essential Essie features into Solr.
• Developed custom components that demonstrated effectiveness in improving biomedical text retrieval.
• Validated the approach on three benchmark biomedical datasets, showing significant improvements.

Conclusions:

• The developed custom Solr components effectively replicate and enhance Essie's biomedical search capabilities.
• This approach offers a sustainable and advanced solution for biomedical text retrieval.
• The enhanced Solr system can aid researchers in more efficient information discovery within the biomedical domain.
