Title: "Experiments on automatic query generation for prior art search"

In this report we aim at identifying discriminative terms in different sections of a query patent which are able to distinguish relevant patents from non-relevant patents. To this end we investigate the term distribution of words occurring in different sections of the query patent and compare them with the rest of the collection using language modeling estimation techniques. We experiment with term weighting based on the KL-divergence between the query patent and the collection and also with parsimonious language model estimation. Both of these techniques promote words that are common in the query patent and rare in the collection. Experiments show the effectiveness of generated queries with BM25 retrieval model on CLEF-IP 2010 dataset.
