Health search engine with e-document analysis for reliable search results.

Area of Science:

• Medical Informatics
• Information Retrieval
• Health Communication

Background:

• Existing solutions for citizen access to eHealth documents are limited.
• There is a need for specialized search engines to ensure the quality and reliability of health information.
• Navigating multilingual medical literature presents significant challenges for the general public.

Purpose of the Study:

• To introduce WRAPIN, an original specialized search engine for retrieving eHealth documents.
• To evaluate the effectiveness of WRAPIN in providing accurate and relevant health information.
• To assess user perception of WRAPIN compared to general-purpose search engines.

Main Methods:

• WRAPIN employs advanced cross-lingual information retrieval technologies.
• It synthesizes medical concepts, conclusions, and references from health literature.
• Utilizes MeSH (Medical Subject Headings) terminology and conclusion extraction for query reformulation.

Main Results:

• Users found WRAPIN results to be informative (65%) and reliable/trustworthy (72%), significantly higher than general search engines (59% and 41%).
• Evaluation identified areas for improvement, including database coverage and user adaptability.
• The WRAPIN prototype demonstrated superior performance in user-perceived quality.

Conclusions:

• WRAPIN is now operational on the Health on the Net (HON) website, freely accessible to citizens.
• It serves as a valuable alternative to general search engines for trustworthy health information.
• WRAPIN empowers citizens to verify medical content and enhance their health literacy.
