Generalizing Representations of Lexical Semantic Relations
We propose a new method for unsupervised learning of embeddings for lexical relations in word pairs. The model is trained on predicting the contexts in which a word pair appears together in corpora, then generalized to account for new and unseen word pairs. This allows us to overcome the data sparsity issues inherent in existing relation embedding learning setups without the need to go back to the corpora to collect additional data for new pairs.Proponiamo un nuovo metodo per lāapprendimento non supervisionato delle rappresentazioni delle relazioni lessicali fra coppie di parole (word pair embeddings). Il modello viene allenato a prevedere i contesti in cui compare uns coppia di parole, e successivamente viene generalizzato a coppie di parole nuove o non attestate. Questo ci consente di superare i problemi dovuti alla scarsitĆ di dati tipica dei sistemi di apprendimento di rappresentazioni, senza la necessitĆ di tornare ai corpora per raccogliere dati per nuove coppie di parole
Proceedings of the Fifth Italian Conference on Computational Linguistics CLiC-it 2018
On behalf of the Program Committee, a very warm welcome to the Fifth Italian Conference on Computational Linguistics (CLiC-Āāit 2018). This edition of the conference is held in Torino. The conference is locally organised by the University of Torino and hosted into its prestigious main lecture hall āCavallerizza Realeā. The CLiC-Āāit conference series is an initiative of the Italian Association for Computational Linguistics (AILC) which, after five years of activity, has clearly established itself as the premier national forum for research and development in the fields of Computational Linguistics and Natural Language Processing, where leading researchers and practitioners from academia and industry meet to share their research results, experiences, and challenges
