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 di�cult 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.
