Head, IT Systems Section Report on IPC-related IT systems 39th session of the IPC Revision Working Group Patrick Fiévet Head, IT Systems Section International Classifications and Standards Division Geneva April 26, 2018

Agenda IPCWLM project / IPCRECLASS IPCPUB IPCCAT-neural cross lingual prototype

IPCWLM Project Status IPCWLMS implementation contract and administrative process: Contract signature: delayed (new target May 1, 2018) Information security requirements clarification in progress Planning to be revised at the end of the clarification period

IPCWLM Project Status Requirements clarification: started Outcome of the IPCWLM Task Force shared with contractor WL simulation report: specification ready to be proposed for approval Analysis of infrastructure and technology aspects Analysis of DOCDB XML fields required by IPCWLMS

IPCRECLASS Stop of email-based submission of RL as from July 1, 2018 New feature (imminent move into production): Possibility to filter by Docdb patent family identifier Interactive reclassification: Occasional issue when adding a new symbol: Scrollbar added

IPCPUB- Status for version 7.6 What is new since IPC CE50: Order of search results is now according to selected search features e.g. if STATS search is used, STATS results appear first. IPCCAT search: possibility to Expand the query box

IPCPUB- query box for IPCCAT search

IPCCAT-neural cross lingual prototype Test with 1000 randomly selected patents in AR, DE, ES, FR, JA, RU, ZH Difficult to compare, not the same distribution of patents

IPCCAT-neural cross lingual prototype Test with 500 randomly selected patents from subclass G06F Losses due to translation are more visible for each language Needs to be evaluated for all languages

IPCCAT-neural cross lingual prototype-potential use in IPC reclassification Next steps: Simulate what cross-lingual text categorization would have done on a past IPC revision instead of Default Transfer Proposed an approach and estimate resources for implementation Report and conclusions for CE 51 decision

Incentive to R&D in text categorization: WIPO-Delta training collection Incentives for research and development institutes interested in automatic text categorization : WIPO DELTA 2018 EN collection available upon request Fully specified XML format 50 million documents classified in the IPC Complement the public WIPO-ALPHA training collection http://www.wipo.int/classifications/ipc/en/ITsupport/Categorization/dataset/index.html
