ATIS - Seven Languages was developed by Amazon Web Services, Inc. and consists of 5,871 English utterances from ATIS (Air Travel Information Services) corpora, specifically ATIS2 (LDC93S5), ATIS3 Training Data (LDC94S19), and ATIS3 Test Data (LDC95S26), translated into six languages: Spanish, German, French, Portuguese, Chinese, and Japanese.

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. 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 of Computer Science, National Institute for Standards and Technology, and SRI International.


The data is separated into 4,978 utterances for training and 893 utterances for testing following the original ATIS division. The training set contains 4,978 utterances selected from the Class A (context independent) training data in the ATIS2 and ATIS3 corpora. The test set contains 893 utterances from the November 1993 and December 1994 data sets in ATIS3.

The original English utterances were manually translated into the six languages. This release also includes the original English utterance. Each utterance is annotated with named entities via table lookup; markers include city, airline, airport names and dates.

Data is stored in UTF-8 encoded tab separated value files.

As of February 15, 2024, an additional set of localized translation files was added for all languages. In these files, the entities were localized to values related to the countries in which the language is spoken rather than simply translated or transliterated (e.g. for German “New York”, would be mapped to “New York” in the test_DE.tsv test set but “München” in the test_DE_loc.tsv test set). They are UTF-8 encoded tab separated value files.
