Introduction to the special issue on patent processing

Technological indicators of nanocellulose advances obtained from data and text mining applied to patent documents

“…To follow progress in nanocellulose, technological indicators can be compiled using quantitative techniques applied to patent documents using well-established procedures, criteria and recommendations in patent statistics [10][11][12][13][14] . Indeed, patent documents are an interesting source of information as it merges technical, legal and business data in a well-establish format 11,12,[14][15][16] . [10][11][12][13][14][15][16][17][18] as well as in technological monitoring and strategic analysis 4,5,10,12,17,18 .…”

[10][11][12][13][14][15][16][17][18] as well as in technological monitoring and strategic analysis 4,5,10,12,17,18 . Patent indicators have also some limitations, though.…”

“…To fulfill this gap, text-mining techniques may help by analyzing unstructured texts (also called free texts) of patent documents, such as titles, abstracts, technical report, claims etc. [14][15][16] Data-and text-mining complement each other in the purpose to build a whole framework of competitors, historical developments and trends, technological monitoring, hotspots, gaps and opportunities to support strategic technological planning 11,14,15,17 . Mining unstructured texts is a newer, empiric and much less developed field when compared to mining structured data of patent documents, thus it has currently been the subject of research [14][15][16][20][21][22][23][24][25][26] .…”

Key Concept Identification for Medical Information Retrieval

“…Patent retrieval (Fujii et al, 2007) is similar to this work, as the queries are usually long and complex patent documents. Several methods have been proposed to construct shorter queries from the documents.…”

Patent Retrieval

“…This survey relies heavily on the proceedings of the SIGIR Workshop on Patent IR in 2000 [97]; the ACL workshop on Patent Corpus Processing [4]; the special issue of the Information Processing & Management journal [59]; the PaIR series of workshops [5], generally co-located with the International Conference on Information and Knowledge Management (CIKM); the Advances in Patent Information Retrieval (AsPIRe) Workshop [76] co-located with the European Conference on Information Retrieval (ECIR) in 2010; as well as the reports from the evaluation campaigns mentioned above. A number of other articles have appeared in various journals, specific to the technology described, and at least another survey has appeared in the World Patent Information (WPI) journal [35].…”
