Towards Learning Through Open-Domain Dialog

no code implementations7 Feb 2022 Eugénio Ribeiro, Ricardo Ribeiro, David Martins de Matos

The development of artificial agents able to learn through dialog without domain restrictions has the potential to allow machines to learn how to perform tasks in a similar manner to humans and change how we relate to them.

Open-Domain Dialog

Automatic Recognition of the General-Purpose Communicative Functions defined by the ISO 24617-2 Standard for Dialog Act Annotation

no code implementations7 Mar 2020 Eugénio Ribeiro, Ricardo Ribeiro, David Martins de Matos

We explore the recognition of general-purpose communicative functions in the DialogBank, which is a reference set of dialogs annotated according to this standard.

Hierarchical Multi-Label Dialog Act Recognition on Spanish Data

no code implementations29 Jul 2019 Eugénio Ribeiro, Ricardo Ribeiro, David Martins de Matos

Concerning the single-label classification problem posed by the top level, we show that the conclusions drawn on English data also hold on Spanish data.

Multi-Label Classification

Deep Dialog Act Recognition using Multiple Token, Segment, and Context Information Representations

no code implementations23 Jul 2018 Eugénio Ribeiro, Ricardo Ribeiro, David Martins de Matos

Recently, most approaches to the task explored different DNN architectures to combine the representations of the words in a segment and generate a segment representation that provides cues for intention.

A Study on Dialog Act Recognition using Character-Level Tokenization

no code implementations18 May 2018 Eugénio Ribeiro, Ricardo Ribeiro, David Martins de Matos

In both cases, the experiments not only show that character-level tokenization leads to better performance than the typical word-level approaches, but also that both approaches are able to capture complementary information.

Assessing User Expertise in Spoken Dialog System Interactions

no code implementations18 Jan 2017 Eugénio Ribeiro, Fernando Batista, Isabel Trancoso, José Lopes, Ricardo Ribeiro, David Martins de Matos

Identifying the level of expertise of its users is important for a system since it can lead to a better interaction through adaptation techniques.

The Influence of Context on Dialogue Act Recognition

no code implementations2 Jun 2015 Eugénio Ribeiro, Ricardo Ribeiro, David Martins de Matos

We performed experiments on the widely explored Switchboard corpus, as well as on data annotated according to the recent ISO 24617-2 standard.
