The WIPO Pearl database has been updated and now contains nearly 230,000 terms, all validated by WIPO-PCT language experts. In addition, over 25,500 concepts (or 88%) 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.
