The ATIS corpora were among the first publications that appeared with the launch of LDC’s catalog in 1993. ATIS0 Complete (LDC93S4A) is comprised of spontaneous speech, read speech and other material from participants in the ATIS collection that is contained in ATIS0 Pilot (LDC93S4B), ATIS0 Read (LDC93S4B-2) and ATIS0 SD-Read (LDC93S4B-3).

The ATIS (Air Travel Information Services) 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. The resulting utterances were recorded and transcribed. 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.

The ATIS collection has been widely used to further research in spoken language understanding and slot filling (Kuo et al., 2020). Other data sets published from the collection include ATIS2 (LDC93S5), ATIS3 Training and Test Data (LDC94S19,LDC95S26) and, more recently, Multilingual ATIS (LDC2019T04) and ATIS - Seven Languages (LDC2021T04).
