Abstract

The biological and biomedical communities have been developing highly structured, rich data sets for representing, analyzing and integrating complex biomed- ical knowledge on the semantic web. However, the complexity of the query languages that have been developed to access these resources makes it difficult for non-technical users to explore the data sets that have been developed, limiting the utility and wide- spread adoption of both the data sets and the query languages. We present VIQUEN, a graphical query engine designed to allow users to express sophisticated queries, which are then compiled into a more complex underlying query language. After the query has been executed, users may explore the resulting graph using VIQUEN’s graph visualiza- tion component. Preliminary evaluation suggests that VIQUEN is capable of expressing a wide variety of real use case biomedical queries.
