NTCIR-7 Patent Mining

The task's goal is the classification of 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 subtasks.

• Japanese subtask: classification of Japanese research papers using patent data written in Japanese.
• English subtask: classification of Japanese research papers using patent data written in English.
• Cross-lingual subtask (J2E): classification of Japanese research papers using patent data written in English.
• Cross-lingual subtask (E2J): classification of English research papers using patent data written in Japanese.

* The entire collection is provided by NII for research purposes.
