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

3. 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

4. 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

5. 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

6. 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

7. IPCPUB- query box for IPCCAT search

8. 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

9. 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

10. 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

11. 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

12. IT operations and support for IPC
