NTCIR-7 Patent Mining Experiments at RALI
NTCIR(2008)
摘要
We participated in the patent mining task at NTCIR7 workshop. Particularly, our experiments focus on English corpus. Based on the Indri search engine, we implemented a patent classification system, which is able to assign a research paper into the IPC system according to the annotated patents in the database. As the task is a cross-genre classification task, we tried several methods to bridge the gap between the research papers and patents. Unfortunately, most the methods do not produce consistent improvements.
