WIPO Pearl Update

It is recalled that WIPO Pearl, WIPO’s multilingual terminology portal, gives 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 publication languages of the PCT. 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.

Improved look and feel

The WIPO Pearl terminology database has been redesigned and now offers a new and improved look and feel.  All of the previous functions have been maintained and the design is based on WIPO’s ePCT system for filing patent applications and so will be familiar to users of that system.  In addition, the website has been adapted for use on mobile devices such as mobile phones and tablets.  Users who wish to send feeback on the new design are invited to do so at:  wipopearl@wipo.int

Interface language

The WIPO Pearl interface is now available also in Arabic, which means that the interface is available in all 10 languages featured in the WIPO Pearl database.  Users can select their language preference at the top right of the screen.

Database contents

The WIPO Pearl database has been updated with 17,000 new patent terms, all validated by WIPO-PCT language experts, and now contains over 178,000 terms. In addition, over 18,000 concepts (or 80%) are linked to other concepts in the database, and these relationships can be browsed in a Concept Map Search.  Further relationships can be shown in unvalidated “concept clouds” produced via a machine learning algorithm.

Collaboration with universities

Over 1,300 multilingual terminology records have recently been provided by students at the following universities, following WIPO’s validation:  the National University of Córdoba (Argentina), the University of Grenoble Alpes (France), Dublin City University (Ireland), the University of Bologna at Forlì (Italy), Astrakhan State University (Russian Federation), the University of Manchester (United Kingdom), the Middlebury Institute of International Studies at Monterey and the University of Illinois at Urbana‑Champaign (United States of America).  Any universities interested in taking part in a terminology collaboration of this kind are invited to contact WIPO at the following e-mail address:  wipopearl@wipo.int
