In this era of "big data", hundreds or even thousands of patent applications arrive every day to patent offices around the world. One of the first tasks of the professional analysts in patent offices is to assign classification codes to... more
In response to growing needs for cross-lingual patent retrieval, we propose PRIME (Patent Retrieval In Multilingual Environment system), in which users can retrieve and browse patents in foreign languages only by their native language.... more
This study explores the benefits of integrating knowledge representations in prior art patent retrieval. Key to the introduced approach is the utilization of human judgment available in the form of classifications assigned to patent... more
Abstract. The combination of different search techniques can improve the results given by each one. In the ongoing R&D project PATExpert1, four different search techniques are combined to perform a patent search. These techniques are:... more
In response to growing needs for cross-lingual patent retrieval, we propose PRIME (Patent Retrieval In Multilingual Environment system), in which users can retrieve and browse patents in foreign languages only by their native language.... more
This paper reports our experimental results at the NTCIR-6 English Patent Retrieval Subtask. Our previous participation at the patent retrieval Subtask revealed that the long length of the patent applications require less smoothing of the... more
In this article, we present ongoing work on an advanced patent processing service PATExpert. The central assumption underlying PATExpert is that in order to meet the needs of the users of patent processing services, recourse must be made... more
The CLEF-IP track was launched in 2009 to investigate IR techniques for patent retrieval, as part of the CLEF 2009 evaluation campaign. We built a system in order to participate in the CLEF-IP track. Our system has three main components:... more
It has been noted before in this book that patent retrieval is different from, and more complicated than “standard” information retrieval. Evaluation of patent retrieval engines has also been shown to require specific attention. In this... more
Abstract. The ClefIp track ran for the first time within Clef 2009. The purpose of the track was twofold: to encourage and facilitate re-search in the area of patent retrieval by providing a large clean data set for experimentation; to... more
