Their label depends on what came before them in the conversation. Ortega and Vu study how neural models can learn a useful representation of preceding utterances for this task. Each utterance and its context are encoded with a… 2. **[Lexico-acoustic Neural-based Models for Dialog Act Classification](https://md.research.elamur.ai/free/en/papers/ortega-2018-lexico-acoustic-neural-based-models/)** *(2018 · 21 citations)* Ortega and Vu ask whether the sound of speech, and not only its transcript, helps assign dialog acts (DAs) such as Statement, Question or Backchannel to utterances in spoken conversation. 3. **[Context-aware Neural-based Dialog Act Classification on Automatically Generated Transcriptions](https://md.research.elamur.ai/free/en/papers/ortega-2019-context-aware-neural-based-dialog/)** *(2019 · 11 citations)* The paper tackles dialog act (DA) classification, which labels each utterance with the speaker's intention, such as a question, statement or backchannel. ## Co-authors here 1 co-author with a page, the most papers together first. - [Ngoc Thang Vu](https://md.research.elamur.ai/free/en/authors/ngoc-thang-vu/) ×3 ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [IEEE International Conference on Acoustics Speech and Signal Processing](https://md.research.elamur.ai/free/en/venues/ieee-international-conference-on-acoustics-speech-and-signal-processing/) ×2: [IEEE International Conference on Acoustics Speech and Signal Processing 2019](https://md.research.elamur.ai/free/en/venues/ieee-international-conference-on-acoustics-speech-and-signal-processing/2019/), [IEEE International Conference on Acoustics Speech and Signal Processing 2018](https://md.research.elamur.ai/free/en/venues/ieee-international-conference-on-acoustics-speech-and-signal-processing/2018/) - [Annual Meeting of the Special Interest Group on Discourse and Dialogue (SIGDIAL)](https://md.research.elamur.ai/free/en/venues/sigdial/): [SIGDIAL 2017](https://md.research.elamur.ai/free/en/venues/sigdial/2017/) ## Cited by Papers of our library cite their works 23 times (of the 141,840 papers whose bibliographies we read); [10 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/daniel-ortega/cited-by/).
