The UCREL semantic analysis system is a software system for undertaking the automatic semantic analysis of text. The system has been designed and used across a number of research projects and this page collects together various pointers to those projects and publications produced over the last 10 years.
The semantic tagset used by USAS was originally loosely based on Tom McArthur's Longman Lexicon of Contemporary English (McArthur, 1981). It has a multi-tier structure with 21 major discourse fields (shown here on the right), subdivided, and with the possibility of further fine-grained subdivision in certain cases. The full tagset is available on-line in plain text form and formatted on one page in PDF. We have also written an introduction to the USAS category system (PDF file) with examples of prototypical words and multi-word units in each semantic field.
