Reliable LLM-based User Simulator for Task-Oriented Dialogue Systems

no code implementations20 Feb 2024 Ivan Sekulić, Silvia Terragni, Victor Guimarães, Nghia Khau, Bruna Guedes, Modestas Filipavicius, André Ferreira Manso, Roland Mathis

Notably, we have observed that fine-tuning enhances the simulator's coherence with user goals, effectively mitigating hallucinations -- a major source of inconsistencies in simulator responses.

MultiWOZ-DF -- A Dataflow implementation of the MultiWOZ dataset

1 code implementation4 Nov 2022 Joram Meron, Victor Guimarães

Semantic Machines (SM) have introduced the use of the dataflow (DF) paradigm to dialogue modelling, using computational graphs to hierarchically represent user requests, data, and the dialogue history [Semantic Machines et al. 2020].

NeuralLog: a Neural Logic Language

1 code implementation4 May 2021 Victor Guimarães, Vítor Santos Costa

Application domains that require considering relationships among objects which have real-valued attributes are becoming even more important.

Boosting Named Entity Recognition with Neural Character Embeddings

no code implementations WS 2015 Cicero Nogueira dos Santos, Victor Guimarães

Most state-of-the-art named entity recognition (NER) systems rely on handcrafted features and on the output of other NLP tasks such as part-of-speech (POS) tagging and text chunking.
