### Dataset Summary | |
The Switchboard Dialog Act Corpus (SwDA) extends the Switchboard-1 Telephone Speech Corpus, Release 2 with | |
turn/utterance-level dialog-act tags. The tags summarize syntactic, semantic, and pragmatic information about the | |
associated turn. The SwDA project was undertaken at UC Boulder in the late 1990s. | |
The SwDA is not inherently linked to the Penn Treebank 3 parses of Switchboard, and it is far from straightforward to | |
align the two resources. In addition, the SwDA is not distributed with the Switchboard's tables of metadata about the | |
conversations and their participants. | |

### Data Splits | |
I used info from the [Probabilistic-RNN-DA-Classifier](https://github.com/NathanDuran/Probabilistic-RNN-DA-Classifier) repo: | |
The same training and test splits as used by [Stolcke et al. (2000)](https://web.stanford.edu/~jurafsky/ws97). | |
The development set is a subset of the training set to speed up development and testing used in the paper [Probabilistic Word Association for Dialogue Act Classification with Recurrent Neural Networks](https://www.researchgate.net/publication/326640934_Probabilistic_Word_Association_for_Dialogue_Act_Classification_with_Recurrent_Neural_Networks_19th_International_Conference_EANN_2018_Bristol_UK_September_3-5_2018_Proceedings). | |

## Dataset Creation | |
### Curation Rationale | |
[More Information Needed] | |
### Source Data | |
#### Initial Data Collection and Normalization | |
The SwDA is not inherently linked to the Penn Treebank 3 parses of Switchboard, and it is far from straightforward to align the two resources Calhoun et al. 2010, §2.4. In addition, the SwDA is not distributed with the Switchboard's tables of metadata about the conversations and their participants. | |
