WIPO Pearl: Enhanced Database

December 1, 2020

The WIPO Pearl database has been updated and now contains over 200,000 terms, all validated by WIPO-PCT language experts. In addition, over 21,000 concepts (or 82%) are linked to other concepts in the database, and these relationships can be browsed in our Concept Map Search. Further relationships can be shown in unvalidated “concept clouds” produced via a machine learning algorithm.

Collaboration with universities

This release also includes multilingual terminology records provided by students at the following universities, following our validation:

We invite universities who are interested in a terminology collaboration of this kind to contact us.

COVID-19 Glossary

WIPO Pearl was recently updated with 147 key concepts related to the COVID-19 pandemic. These key concepts are provided in the 10 languages of the database and comprise in total 1,500 terms. The aim is to help provide consistency and clarity across different languages regarding key terminology of the COVID-19 pandemic. These COVID-19 terms are also available in a separate glossary which contains links to the Full Record in WIPO Pearl for each concept, where definitions, multilingual equivalents, contexts, and concept maps can be found. The glossary is also linked to PATENTSCOPE, allowing any patents containing these terms to be easily located. Finally, this collection of COVID-19 terms is available for download from the glossary.
