WIPO Pearl Update: New Interface Languages; Database and Feature Improvements
It is recalled that WIPO Pearl, WIPO’s multilingual terminology portal, provides free access to a wealth of scientific and technical terms derived from PCT applications and national patent documents, as well as to key PCT legal terms, in all 10 PCT publication languages. It helps to promote accurate and consistent use of terms across those languages, and makes it easier to search and share scientific and technical knowledge.
WIPO Pearl is available at:
New interface languages
The WIPO Pearl interface is now available in Chinese and Portuguese, in addition to English, French, Japanese, Russian and Spanish. Users can select their language preference at the top right‑hand side of the screen. Arabic, German and Korean versions are under development.
The terminology database has been updated with 7,000 new terms (new total: 127,000) and 500 new concept relations (new total: 17,500), which have all been entered and validated by WIPO‑PCT language experts. About 12,500 concepts are linked to other concepts in the database, and these relationships can be browsed in the Concept Map Search.
New feature: Concept Path Search
The Concept Path Search, a new feature in Concept Map Search, allows users to find the path between two concepts, showing all the related concepts in between. This is especially helpful when concept maps are large and complex. An enhancement to Concept Path Search which is currently under development will allow all terms found in a concept path to be sent directly to PATENTSCOPE for use in a combined keyword search.
PCT legal terms
All PCT legal terms in Arabic, Chinese, English, French, German, Japanese, Russian and Spanish have been reviewed and validated by PCT legal experts at WIPO and awarded the highest term reliability score of “4”, thus providing a highly reliable reference for PCT legal terminology in different languages.
Collaboration with universities
Terminology collaborations are currently underway with the following universities:
– University of Geneva, Switzerland
– Université Grenoble Alpes, France
– Aristotle University of Thessaloniki, Greece
– University of Illinois at Urbana‑Champaign, USA
As part of their coursework, terminology students are providing WIPO with bi- or trilingual terminology records in specific technical fields for inclusion in WIPO Pearl following their validation. Any other universities interested in a terminology collaboration of this kind can contact WIPO at the following e‑mail address: firstname.lastname@example.org
