Running CLEF-IP Experiments using a Graphical Query Builder.
Wouter Alink, Roberto Cornacchia, Arjen P. de Vries · 2009
The CWI submission for the CLEF-IP track shows results for out-of-the-box query-ing using a graphical strategy design interface. This domain-independent search plat-form has been enriched with patent-specific information, which was then readily avail-able to the query interface. The search strategies for the 4 runs submitted have been constructed by simple drag&drop operations in this graphical interface, subsequently compiled into probabilistic relational algebra (PRA) [3] and SQL, and then executed on a relational high-performance database system [2]. The four search strategies compare boolean search, ranked retrieval, and category-based re-ranking. The main lesson learned is that using selection on category only yields a high recall.
