We Need to Consider Disagreement in Evaluation

no code implementations ACL (BPPF) 2021 Valerio Basile, Michael Fell, Tommaso Fornaciari, Dirk Hovy, Silviu Paun, Barbara Plank, Massimo Poesio, Alexandra Uma

Instead, we suggest that we need to better capture the sources of disagreement to improve today’s evaluation practice.

SemEval-2023 Task 11: Learning With Disagreements (LeWiDi)

no code implementations28 Apr 2023 Elisa Leonardelli, Alexandra Uma, Gavin Abercrombie, Dina Almanea, Valerio Basile, Tommaso Fornaciari, Barbara Plank, Verena Rieser, Massimo Poesio

We report on the second LeWiDi shared task, which differs from the first edition in three crucial respects: (i) it focuses entirely on NLP, instead of both NLP and computer vision tasks in its first edition; (ii) it focuses on subjective tasks, instead of covering different types of disagreements-as training with aggregated labels for subjective NLP tasks is a particularly obvious misrepresentation of the data; and (iii) for the evaluation, we concentrate on soft approaches to evaluation.

Sentiment Analysis

Leveraging Social Interactions to Detect Misinformation on Social Media

no code implementations6 Apr 2023 Tommaso Fornaciari, Luca Luceri, Emilio Ferrara, Dirk Hovy

Keeping track of the sequence of the interactions during the time, we improve over previous state-of-the-art models.

SemEval-2021 Task 12: Learning with Disagreements

no code implementations SEMEVAL 2021 Alexandra Uma, Tommaso Fornaciari, Anca Dumitrache, Tristan Miller, Jon Chamberlain, Barbara Plank, Edwin Simpson, Massimo Poesio

Disagreement between coders is ubiquitous in virtually all datasets annotated with human judgements in both natural language processing and computer vision.

Dense Node Representation for Geolocation

no code implementations WS 2019 Tommaso Fornaciari, Dirk Hovy

Prior research has shown that geolocation can be substantially improved by including user network information.

Identifying Linguistic Areas for Geolocation

no code implementations WS 2019 Tommaso Fornaciari, Dirk Hovy

We create three sets of labels at different levels of granularity, and compare performance of a state-of-the-art geolocation model trained and tested with P2C labels to one with regular k-d tree labels.

Geolocation with Attention-Based Multitask Learning Models

no code implementations WS 2019 Tommaso Fornaciari, Dirk Hovy

Geolocation, predicting the location of a post based on text and other information, has a huge potential for several social media applications.

Increasing In-Class Similarity by Retrofitting Embeddings with Demographic Information

1 code implementation EMNLP 2018 Dirk Hovy, Tommaso Fornaciari

We use homophily cues to retrofit text-based author representations with non-linguistic information, and introduce a trade-off parameter.
