ATIS2 contains approximately 15,000 utterances from 450 participants in the ATIS (Air Travel Information Services) collection. The ATIS collection was developed to support the research and development of speech understanding systems. Participants were presented with various hypothetical travel planning scenarios and asked to solve them by interacting with partially or completely automated ATIS systems.
Data was collected in the early 1990s at five US sites: Raytheon BBN, Carnegie Mellon University, MIT Laboratory for Computer Science, National Institute for Standards and Technology and SRI International.
All utterances were recorded and transcribed and approximately 10,000 were annotated with categorizations and canonical reference answers.
For ATIS2, the ATIS0 ten-city relational database was revised to accommodate connecting flights and fares and some table headings were renamed.
This release includes training data and the February 1992 and November 1992 ATIS benchmark tests. Each set contains approximately 1,000 utterances from the pool of data collected by the five sites.
