ReVeaLD: a user-driven domain-specific interactive search platform for biomedical research

Area of Science:

• Bioinformatics and Computational Biology
• Biomedical Data Integration
• Visual Analytics

Background:

• Life sciences specialization and increased biomedical datasets necessitate advanced data discovery methods.
• Semantic web technologies offer potential for data integration but face usability challenges for non-technical researchers.
• Intuitive interaction with distributed data sources is crucial for biomedical experts to exploit integrated information.

Purpose of the Study:

• To introduce ReVeaLD (Real-time Visual Explorer and Aggregator of Linked Data), a user-centered visual analytics platform.
• To enhance intuitive interaction with data from distributed sources for biomedical researchers.
• To improve the usability of semantic web technologies in bioinformatics research.

Main Methods:

• Developed a user-centered visual analytics platform (ReVeaLD) using Scalable Vector Graphics and JavaScript.
• Implemented a domain-specific language (DSL) for query formulation, mapped to a self-updating catalogue of external data elements.
• Designed user-defined graphic rules for information display via media-rich interfaces.
• Evaluated the platform through a game-based assessment with biomedical researchers formulating challenge questions.

Main Results:

• ReVeaLD facilitates intuitive interaction with distributed data sources.
• Complex queries were formulated in under two minutes by researchers unfamiliar with the platform.
• Supporting domain-specific language (DSL) element identification significantly improved platform intuitiveness and usability.

Conclusions:

• ReVeaLD enhances the ability of biomedical researchers to discover and correlate data from diverse sources.
• The platform demonstrates the potential of visual analytics and domain-specific languages to bridge the gap in semantic web technology adoption.
• ReVeaLD offers a promising solution for more accessible and efficient biomedical data exploration.
