NTCIR-8 Patent Mining Task

Test Collection
The task's goal is to create technical trend map from research papers and patents. This task consists of the following two subtasks.

(1) Research Paper Classification Subtask

This task aims to classify research papers written in either Japanese or English in terms of the International Patent Classification (IPC) system, which is a global standard hierarchical patent classification system. This test collection is intended to evaluate the following four different tasks.

(2) Technical Trend Map Creation Subtask

This task aims to extract elemental technologies and their effects from research papers and patents. This test collection is intended to evaluate the following two different tasks. The document collection includes unexamined Japanese patent applications published in 1993-2002, Patent Abstracts of Japan published in 1993-2002, patent grant data published from USPTO in 1993-2002, author abstracts of papers presented at the academic conference hosted by either of 65 academic societies in 1988-1997, additional author abstracts of the academic conference paper database in 1997-1999, and Grant Reports in 1988-1997. The document collection does not include diagrams.
