1. Report on IPC-related IT systems IPC Revision Working Group 40
Geneva
November 16, 2018
Patrick Fiévet
Head of IT Systems Section
International Classifications and Standards Division

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

3. IPCWLM Project Status IPCWLMS implementation contract:
Contract signed: June 2018
Clarification phase: July to October 2018
Planning revised at the end of the clarification period targets IPCWLMS first production use for Q4 2019

4. IPCWLMS Analysis phase completed
New requirements identified:
Multiple revisions warning file: to alert when the same symbol appears in several IPC revisions (For on-line and off-line reclassification)
Reclassification symbols validity checking against all RCL of pending IPC reclassifications
Analysis of DOCDB XML fields required by IPCWLMS
Commercial offer and timelines for implementation

5. IPCWLMS Implementation phase
IPCWLMS1 targeted end: Q1 2019
Infrastructure & remote access (including for WIPO delta)
DOCDB XML excerpts processing
WL creation and distribution algorithm

6. IPCWLMS Implementation phase
IPCWLMS1 targeted end: Q1 2019
Simulation files (WL and automatic RL files)
Testing of simulation files by volunteering Offices based on IPC (and August 2018 DOCDB XML full extract ?): Jan. 15 to Feb. 10, 2019
Report about simulation: CE 51 ~Feb. 15, 2019

7. IPCWLMS Implementation phase
IPCWLMS2: targeted end Q (IPC WL)
Management of Intellectual Reclassification essentially based on IPCRECLASS functionality (~Jun. 2019) + Test by volunteering Offices?
Management of Residual WLs, reclassification statistics, (~Aug. 2019)
Freeze of IPC reclassification for the Transition from IPCRECLASS to IPCWLMS (~ SepT. 2019)
Support services(~Oct. 2019)

8. IPCRECLASS Email-based submission of RL Stopped (as from July 1, 2018)
WL for IPC to be produced by the EPO for the last time i.e. according to legacy distribution algorithm

9. IPCPUB- IPCCAT IPCCAT neural retrained with DOCDB XML 2018 :
Coverage at Maingroup level: EN 99% FR 90%
Precision at Maingroup level: EN 89% FR 83%
Coverage at subgroup level: EN 99% FR 90%
Precision at subgroup level: EN 82% FR 73%

10. IPCCAT-neural cross lingual prototype
Just completed tests:
comparison between:
cross lingual IPCCAT EN taking FR documents as input
Native FR IPCCAT taking the same FR documents as input
Preliminary conclusion: Focus WIPO resources on only one instance of IPCCAT neural cross lingual, trained with EN collection + automatic translation based on WIPO translate
More conclusions and detailed results will be disclosed at the opportunity of IPC CE 51

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 and FR collections available upon request since April 2018
More than 40 R&D institutes requested WIPO Delta in the past 6 months

12. IT operations and support for IPC
