THematic Indexing of Spoken Language

Annual Report 1999


The aim of the THISL project was to produce a broadcast news retrieval demonstrator for the BBC. The approach adopted was to transcribe radio and television broadcasts using the Abbot speech recognizer and then to index the resulting transcriptions using the thislIR information retrieval system - similar to a web search engine - which allows users to search for news items of interest to them. thislIR returns a list of news clips most relevant to each query which users can listen to. Demonstrators have been produced with both text and spoken query interfaces. The news retrieval demonstrator is currently being evaluated by the BBC. A French language system is under development.
