ABSTRACT
The most fundamental innovation of products is the innovation of functional principle. Learning from the functional information of existing patents plays an important role in the design of product innovation and patent circumvention. This paper proposed a similar patent search method of fusion function information. The method firstly screening candidate words, the candidate word is the word which is of great contribution to judge whether a sentence contains functional information; the short text classification method based on the candidate words was proposed to judge the functional sentences, and the functional expression rules were combined to determine the patent's functional phrase. Finally, based on the functional expression sentences, this paper proposed a sentence similarity computing method based on word2vec and syntactic dependency to search for the patents which have similar functional information. Experiments show that the proposed method has a certain accuracy and validity in the automatic extraction of functional information and search for similar patent.

An investigation of decompounding for cross-language patent search
SIGIR '11: Proceedings of the 34th international ACM SIGIR conference on Research and development in Information RetrievalDecompounding 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. This poses two challenges: i) ...
