An increasing number of biological databases have been made available in the form of RDF that are accessible through SPARQL endpoints. These endpoints offer a valuable opportunity to utilize the RDF datasets as integrative databases. However, writing a SPARQL query often becomes a burden for biologists; thus, an easy-to-use querying tool for the SPARQL endpoints is necessary. Here, we developed...

Mining SPARQL queries to understand the behavior of automated programs (or machine agents) is an important step in designing systems for the semantic web. We present techniques that differ from state-of-the-art SPARQL mining techniques in two ways: 1. Move away from one SPARQL query at a time view to SPARQL user session view 2. Look at the results of SPARQL queries in addition to the query itse...

SPARQL-Proxy is a portable Web application that works as a proxy server of a SPARQL endpoint. It provides several functions such as job scheduling for SPARQL queries, validating the safety of query statements, and caching of SPARQL search results to improve response time performance.

Metadata publication in accordance with the semantic web as a database is a trend for providing and integrating various life-science data. These metadata are published as SPARQL endpoints, a standardised API for RDF datasets. As life-science data are very widely diverse and described using various ontologies and data classes, writing an efficient SPARQL query for SPARQL endpoints is difficult f...

SPARQL queries have become the standard for querying linked open data knowledge bases, but SPARQL query construction can be challenging and timeconsuming even for experts. SPARQL query generation from natural language questions is an attractive modality for interfacing with LOD. However, how to evaluate SPARQL query generation from natural language questions is a mostly open research question. ...
