Examining the Robustness of Evaluation Metrics for Patent Retrieval with Incomplete Relevance Judgements [PDF]

open access: yes, 2010
Recent years have seen a growing interest in research into patent retrieval. One of the key issues in conducting information retrieval (IR) research is meaningful evaluation of the effectiveness of the retrieval techniques applied to task under ...

Patent query reduction using pseudo relevance feedback [PDF]

open access: yes, 2011
Queries in patent prior art search, being full patent applications, are very much longer than standard ad hoc search and web search topics. Standard information retrieval (IR) techniques are not entirely effective for patent prior art search because of ...

Exploring structured documents and query formulation techniques for patent retrieval [PDF]

open access: yes, 2009
This paper presents the experiments and results of DCU in CLEF-IP 2009. Our work applied standard information retrieval (IR) techniques to patent search. Different experiments tested various methods for the patent retrieval, including query formulation,

Utilizing sub-topical structure of documents for information retrieval. [PDF]

open access: yes, 2011
Text segmentation in natural language processing typically refers to the process of decomposing a document into constituent subtopics. Our work centers on the application of text segmentation techniques within information retrieval (IR) tasks.

PRES: A score metric for evaluating recall-oriented information retrieval applications [PDF]

open access: yes, 2010
Information retrieval (IR) evaluation scores are generally designed to measure the effectiveness with which relevant documents are identified and retrieved. Many scores have been proposed for this purpose over the years. These have primarily focused on

A study of query expansion methods for patent retrieval [PDF]

open access: yes, 2011
Patent retrieval is a recall-oriented search task where the objective is to find all possible relevant documents. Queries in patent retrieval are typically very long since they take the form of a patent claim or even a full patent application in the ...

An efficient method for using machine translation technologies in cross-language patent search [PDF]

open access: yes, 2011
Topics in prior-art patent search are typically full patent applications and relevant items are patents often taken from sources in different languages.

Simple vs. sophisticated approaches for patent prior-art search [PDF]

open access: yes, 2011
Patent prior-art search is concerned with finding all filed patents relevant to a given patent application. We report a comparison between two search approaches representing the state-of-the-art in patent prior-art search.

An investigation of decompounding for cross-language patent search [PDF]

open access: yes, 2011
Decompounding has been found to improve information retrieval (IR) effectiveness in general domains for languages such as German or Dutch. We investigate if cross-language patent retrieval can profit from decompounding.

Toward higher effectiveness for recall-oriented information retrieval: A patent retrieval case study [PDF]

open access: yes, 2012
Research in information retrieval (IR) has largely been directed towards tasks requiring high precision. Recently, other IR applications which can be described as recall-oriented IR tasks have received increased attention in the IR research domain ...
