  • Extending WordNet with fine-grained collocational information via supervised distributional learning
    Espinosa-Anke, Luis; Camacho-Collados, Jose; Rodríguez Fernández, Sara; Saggion, Horacio; Wanner, Leo (COLING, 2016)
    WordNet is probably the best known lexical resource in Natural Language Processing. While it/nis widely regarded as a high quality repository of concepts and semantic relations, updating and/nextending it manually is costly. ...
  • Finding and expanding hypernymic relations in the music domain
    Espinosa-Anke, Luis; Oramas, Sergio; Camacho-Collados, Jose; Saggion, Horacio (2016)
    Lexical taxonomies are tree or directed acyclic graph-like structures where each node represents a concept and each edge encodes a binary hypernymic (is-a) relation. These lexical resources are useful for AI tasks like ...
  • How gender and skin tone modifiers affect emoji semantics in Twitter
    Barbieri, Francesco; Camacho-Collados, Jose (ACL (Association for Computational Linguistics), 2018)
    In this paper we analyze the use of emojis in social media with respect to gender and skin tone. By gathering a dataset of over twenty two million tweets from United States some findings are clearly highlighted after ...
  • How gender and skin tone modifiers affect emoji semantics in Twitter
    Barbieri, Francesco; Camacho-Collados, Jose (ACL (Association for Computational Linguistics), 2018)
    In this paper we analyze the use of emojis in social media with respect to gender and skin tone. By gathering a dataset of over twenty two million tweets from United States some findings are clearly highlighted after ...
  • Interpretable emoji prediction via label-wise attention LSTMs
    Barbieri, Francesco; Espinosa-Anke, Luis; Camacho-Collados, Jose; Schockaert, Steven; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    Human language has evolved towards newer forms of communication such as social media, where emojis (i.e., ideograms bearing a visual meaning) play a key role. While there is an increasing body of work aimed at ...
  • SemEval 2018 Task 2: multilingual emoji prediction
    Barbieri, Francesco; Camacho-Collados, Jose; Ronzano, Francesco; Espinosa-Anke, Luis; Ballesteros, Miguel; Basile, Valerio; Patti, Viviana; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    This paper describes the results of the first shared task on Multilingual Emoji Prediction, organized as part of SemEval 2018. Given the text of a tweet, the task consists of predicting the most likely emoji to be used ...
  • SemEval-2018 Task 9: hypernym discovery
    Camacho-Collados, Jose; Delli Bovi, Claudio; Espinosa-Anke, Luis; Oramas, Sergio; Pasini, Tommaso; Santus, Enrico; Shwartz, Vered; Navigli, Roberto; Saggion, Horacio (ACL (Association for Computational Linguistics), 2018)
    This paper describes the SemEval 2018 Shared Task on Hypernym Discovery. We put forward this task as a complementary benchmark for modeling hypernymy, a problem which has traditionally been cast as a binary classification ...
  • Supervised distributional hypernym discovery via domain adaptation
    Espinosa-Anke, Luis; Camacho-Collados, Jose; Delli Bovi, Claudio; Saggion, Horacio (ACL (Association for Computational Linguistics), 2016)
    Lexical taxonomies are graph-like hierarchical structures that provide a formal representation of knowledge. Most knowledge graphs to date rely on is-a (hypernymic) relations as the backbone of their semantic structure. ...
