Assessing the Quality of Human-Generated Summaries with Weakly Supervised Learning

no code implementations NoDaLiDa 2021 Joakim Olsen, Arild Brandrud Næss, Pierre Lison

This paper explores how to automatically measure the quality of human-generated summaries, based on a Norwegian corpus of real estate condition reports and their corresponding summaries.

A Graph-to-Text Approach to Knowledge-Grounded Response Generation in Human-Robot Interaction

no code implementations3 Nov 2023 Nicholas Thomas Walker, Stefan Ultes, Pierre Lison

After this conversion, the text representation of the dialogue state graph is included as part of the prompt of a large language model used to decode the agent response.

Neural Text Sanitization with Privacy Risk Indicators: An Empirical Analysis

no code implementations22 Oct 2023 Anthi Papadopoulou, Pierre Lison, Mark Anderson, Lilja Øvrelid, Ildikó Pilán

The text sanitization process starts with a privacy-oriented entity recognizer that seeks to determine the text spans expressing identifiable personal information.

Retrieval-Augmented Neural Response Generation Using Logical Reasoning and Relevance Scoring

no code implementations20 Oct 2023 Nicholas Thomas Walker, Stefan Ultes, Pierre Lison

Constructing responses in task-oriented dialogue systems typically relies on information sources such the current dialogue state or external databases.

Conversational Feedback in Scripted versus Spontaneous Dialogues: A Comparative Analysis

no code implementations27 Sep 2023 Ildikó Pilán, Laurent Prévot, Hendrik Buschmeier, Pierre Lison

This difference is particularly marked for communicative feedback and grounding phenomena such as backchannels, acknowledgments, or clarification requests.

Who's in Charge? Roles and Responsibilities of Decision-Making Components in Conversational Robots

no code implementations15 Mar 2023 Pierre Lison, Casey Kennington

Software architectures for conversational robots typically consist of multiple modules, each designed for a particular processing task or functionality.

GraphWOZ: Dialogue Management with Conversational Knowledge Graphs

1 code implementation23 Nov 2022 Nicholas Thomas Walker, Stefan Ultes, Pierre Lison

We present a new approach to dialogue management using conversational knowledge graphs as core representation of the dialogue state.

Bootstrapping Text Anonymization Models with Distant Supervision

1 code implementation LREC 2022 Anthi Papadopoulou, Pierre Lison, Lilja Øvrelid, Ildikó Pilán

Instead of requiring manually labeled training data, the approach relies on a knowledge graph expressing the background information assumed to be publicly available about various individuals.

skweak: Weak Supervision Made Easy for NLP

1 code implementation ACL 2021 Pierre Lison, Jeremy Barnes, Aliaksandr Hubin

skweak is especially designed to facilitate the use of weak supervision for NLP tasks such as text classification and sequence labelling.

Not All Dialogues are Created Equal: Instance Weighting for Neural Conversational Models

no code implementations WS 2017 Pierre Lison, Serge Bibauw

Neural conversational models require substantial amounts of dialogue data for their parameter estimation and are therefore usually learned on large corpora such as chat forums or movie subtitles.

Redefining Context Windows for Word Embedding Models: An Experimental Study

no code implementations WS 2017 Pierre Lison, Andrey Kutuzov

Distributional semantic models learn vector representations of words through the contexts they occur in.
