Unsupervised Term Extraction for Highly Technical Domains

no code implementations24 Oct 2022 Francesco Fusco, Peter Staar, Diego Antognini

Developing term extractors that are able to generalize across very diverse and potentially highly technical domains is challenging, as annotations for domains requiring in-depth expertise are scarce and expensive to obtain.

Assistive Recipe Editing through Critiquing

no code implementations5 May 2022 Diego Antognini, Shuyang Li, Boi Faltings, Julian McAuley

Prior studies have used pre-trained language models, or relied on small paired recipe data (e. g., a recipe paired with a similar one that satisfies a dietary constraint).

Positive and Negative Critiquing for VAE-based Recommenders

no code implementations5 Apr 2022 Diego Antognini, Boi Faltings

As a result of revisiting critiquing from the perspective of multimodal generative models, recent work has proposed M&Ms-VAE, which achieves state-of-the-art performance in terms of recommendation, explanation, and critiquing.

pNLP-Mixer: an Efficient all-MLP Architecture for Language

1 code implementation9 Feb 2022 Francesco Fusco, Damian Pascual, Peter Staar, Diego Antognini

Large pre-trained language models based on transformer architecture have drastically changed the natural language processing (NLP) landscape.

Multi-Step Critiquing User Interface for Recommender Systems

no code implementations13 Jul 2021 Diana Petrescu, Diego Antognini, Boi Faltings

Recommendations with personalized explanations have been shown to increase user trust and perceived quality and help users make better decisions.

Recommendation Systems

Rationalization through Concepts

no code implementations Findings (ACL) 2021 Diego Antognini, Boi Faltings

One type of explanation is a rationale, i. e., a selection of input features such as relevant text snippets from which the model computes the outcome.

Fast Multi-Step Critiquing for VAE-based Recommender Systems

no code implementations3 May 2021 Diego Antognini, Boi Faltings

Experiments on four real-world datasets demonstrate that among state-of-the-art models, our system is the first to dominate or match the performance in terms of recommendation, explanation, and multi-step critiquing.

Addressing Fairness in Classification with a Model-Agnostic Multi-Objective Algorithm

no code implementations9 Sep 2020 Kirtan Padh, Diego Antognini, Emma Lejal Glaude, Boi Faltings, Claudiu Musat

The goal of fairness in classification is to learn a classifier that does not discriminate against groups of individuals based on sensitive attributes, such as race and gender.

Interacting with Explanations through Critiquing

no code implementations22 May 2020 Diego Antognini, Claudiu Musat, Boi Faltings

Using personalized explanations to support recommendations has been shown to increase trust and perceived quality.

GameWikiSum: a Novel Large Multi-Document Summarization Dataset

1 code implementation LREC 2020 Diego Antognini, Boi Faltings

In this paper, we propose GameWikiSum, a new domain-specific dataset for multi-document summarization, which is one hundred times larger than commonly used datasets, and in another domain than news.

Multi-Dimensional Explanation of Reviews

no code implementations25 Sep 2019 Diego Antognini, Claudiu Musat, Boi Faltings

Neural models achieved considerable improvement for many natural language processing tasks, but they offer little transparency, and interpretability comes at a cost.

Learning to Create Sentence Semantic Relation Graphs for Multi-Document Summarization

no code implementations WS 2019 Diego Antognini, Boi Faltings

To overcome these limitations, we present a novel method, which makes use of two types of sentence embeddings: universal embeddings, which are trained on a large unrelated corpus, and domain-specific embeddings, which are learned during training.
