The CoQA material used in ATIR was obtained from the official [`stanfordnlp/coqa`](https://huggingface.co/datasets/stanfordnlp/coqa) release, which is itself marked as `license: other` because it contains records governed by different upstream terms.

## Modification notice

ATIR contains modified and derived versions of upstream data. These records are not the original LibriSpeech, SVQ, CoQA, MCTest, RACE, or DeepMind CNN datasets.

The source data were processed and modified by the ATIR authors as part of the ATIR dataset construction pipeline. 

For MCTest-derived records, this notice is provided pursuant to the MSR-LA requirement that modified files identify that the data have been changed and state the date of modification.

## Redistribution

Redistribution or mirroring is permitted only when the redistributor:

1. Preserves this complete license and provenance notice.
2. Preserves all applicable upstream licenses, attribution notices, and citations.
3. Applies the relevant terms on a component-by-component basis.
4. Distributes MCTest-derived data and derivative works under the same MSR-LA terms and includes the required modification notice.
5. Limits RACE-derived data to non-commercial research use and complies with the RACE terms.
6. Applies CC BY-SA 4.0 to relevant adaptations of the CoQA literature and Wikipedia material.
7. Does not represent the complete ATIR dataset as being governed by a single permissive license.
8. Identifies the official ATIR repository as the canonical source: https://huggingface.co/datasets/Tung111/ATIR

This release does not grant any additional rights to third-party content beyond those provided by the respective upstream licenses.

## Citation

Users of ATIR should cite the ATIR paper and the applicable upstream datasets.

    abstract = "Audio carries richer information than text, including emotion, speaker traits, and environmental context, while also enabling lower-latency processing compared to speech-to-text pipelines. However, recent multimodal information retrieval research has predominantly focused on images, largely overlooking audio, especially in the setting of interleaved audio-text contextual retrieval. In this work, we introduce the Audio-Text Interleaved contextual Retrieval (ATIR) task, where queries can alternate between audio and text modalities. We construct an ATIR benchmark by integrating several Automatic Speech Recognition (ASR), QA, and retrieval datasets, ultimately unifying four types of contextual retrieval tasks. This benchmark substantially addresses the limitations of existing audio retrieval datasets in semantic retrieval. To study this task, we evaluate several off-the-shelf retrievers and train our ATIR model based on a Multimodal Large Language Model (MLLM). We further propose a novel token compression mechanism, which is orthogonal to existing compression methods, to mitigate the challenge of excessive audio tokens in MLLM-based ATIR models. Experimental results show that our ATIR model achieves significant improvements over strong baselines."
