For a researcher in a field of great industrial relevance, retrieving and analyzing research papers and patents has become an important aspect of assessing the scope of the field. We propose a method for creating a technical trend map automatically from both research papers and patents. For the construction of the technical trend map, we focus on the(More)
Our group participated in the subtask of technical trend map creation for the NTCIR-8 Patent Mining Task. We prepared five types of cue phrase list using statistical methods, and used them in the analysis of research papers and patents based on the Support Vector Machines. From the experimental results, we obtained Recall of 0.110 and Precision of 0.424 for(More)
