The 2019 evaluation was conducted in two parts: (1) a leaderboard-style challenge based on conversational telephone speech from LDC's Call My Net 2 (CMN2) corpus; and (2) a separate evaluation using audio-visual material collected by LDC for the VAST (Video Annotation for Speech Technology) project (released as LDC2023V01https://catalog.ldc.upenn.edu/LDC2023V01).
The telephone speech data for the CTS Challenge was drawn from the CMN2 collection conducted by LDC in Tunisia in which Tunisian Arabic speakers called friends or relatives who agreed to record their telephone conversations lasting between 8-10 minutes. The speech segments include PSTN (public switched telephone network) and VOIP (voice over IP) data.
2023 members can access this corpus through their LDC accounts. Non-members may license this data for a fee. * LORELEI Zulu Representative Language Packhttps://catalog.ldc.upenn.edu/LDC2023T06 is comprised of over 5 million words of Zulu monolingual text, 2.7 million words of found Zulu-English parallel text, and 71,000 Zulu words translated from English data. Approximately 100,000 words were annotated for named entities and over 23,000 words were annotated for entity discovery and linking and situation frames (identifying entities, needs, and issues). Data was collected from discussion forum, news, reference, social network, and weblogs.
The LORELEI (Low Resource Languages for Emergent Incidents) program was concerned with building human language technology for low resource languages in the context of emergent situations. Representative languages were selected to provide broad typological coverage.
The knowledge base for entity linking annotation is available separately as LORELEI Entity Detection and Linking Knowledge Base (LDC2020T10)https://catalog.ldc.upenn.edu/LDC2020T10.
