Improving Out-of-Scope Detection in Intent Classification by Using Embeddings of the Word Graph Space of the Classes

no code implementations EMNLP 2020 Paulo Cavalin, Victor Henrique Alves Ribeiro, Ana Appel, Claudio Pinhanez

This paper explores how intent classification can be improved by representing the class labels not as a discrete set of symbols but as a space where the word graphs associated to each class are mapped using typical graph embedding techniques.

Exploring the Advantages of Dense-Vector to One-Hot Encoding of Intent Classes in Out-of-Scope Detection Tasks

no code implementations18 May 2022 Claudio Pinhanez, Paulo Cavalin

This work explores the intrinsic limitations of the popular one-hot encoding method in classification of intents when detection of out-of-scope (OOS) inputs is required.

Using Meta-Knowledge Mined from Identifiers to Improve Intent Recognition in Neuro-Symbolic Algorithms

no code implementations16 Dec 2020 Claudio Pinhanez, Paulo Cavalin, Victor Ribeiro, Heloisa Candello, Julio Nogima, Ana Appel, Mauro Pichiliani, Maira Gatti de Bayser, Melina Guerra, Henrique Ferreira, Gabriel Malfatti

By using neuro-symbolic algorithms able to incorporate such proto-taxonomies to expand intent representation, we show that such mined meta-knowledge can improve accuracy in intent recognition.

A Hybrid Solution to Learn Turn-Taking in Multi-Party Service-based Chat Groups

no code implementations14 Jan 2020 Maira Gatti de Bayser, Melina Alberio Guerra, Paulo Cavalin, Claudio Pinhanez

To predict the next most likely participant to interact in a multi-party conversation is a difficult problem.

Learning Multi-Party Turn-Taking Models from Dialogue Logs

no code implementations3 Jul 2019 Maira Gatti de Bayser, Paulo Cavalin, Claudio Pinhanez, Bianca Zadrozny

This paper investigates the application of machine learning (ML) techniques to enable intelligent systems to learn multi-party turn-taking models from dialogue logs.
