PepeSearch: Semantic Data for the Masses

Area of Science:

• Computer Science
• Information Science

Background:

• The Web of Data is rapidly expanding, increasing the need for accessible tools to search and explore semantic datasets.
• Current semantic data tools often require specialized knowledge, such as SPARQL/RDF, limiting access for mainstream users.

Purpose of the Study:

• To introduce PepeSearch, a portable tool designed for non-expert users to search and explore semantic datasets.
• To evaluate the effectiveness and usability of PepeSearch for searching a large, real-world linked open data resource.

Main Methods:

• PepeSearch features an automatically generated multi-class search form based on SPARQL endpoints.
• The tool was tested with 15 participants performing non-trivial searches on a Linked Open Data version of the Norwegian Register of Business Enterprises.
• Portability was assessed by configuring PepeSearch to query different SPARQL endpoints.

Main Results:

• Participants achieved high retrieval performance when using PepeSearch.
• Usability ratings for PepeSearch were very positive, indicating user-friendliness.
• The tool demonstrated portability by successfully querying diverse SPARQL endpoints.

Conclusions:

• PepeSearch is an effective tool for enabling mainstream users to search semantic datasets.
• The positive results suggest PepeSearch can bridge the gap between complex semantic data and general users.
• The tool's portability enhances its utility across various semantic data sources.
