Abstract

Modern personal assistants require to access unstructured information in order to successfully fulfill user requests. In this paper, we have studied the use of two machine learning components to design personal assistants: intent classification, to understand the user request, and answer sentence selection, to carry out question answering from unstructured text. The evaluation results derived on five different real-world datasets, associated with different companies, show high accuracy for both tasks. This suggests that modern QA and dialog technology is effective for real-world tasks.

Abstract

On behalf of the Program Committee, a very warm welcome to the Seventh Italian Conference on Computational Linguistics (CLiC-it 2020). This edition of the conference is held in Bologna and organised by the University of Bologna. The CLiC-it conference series is an initiative of the Italian Association for Computational Linguistics (AILC) which, after six 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.

Abstract

In this paper, we describe our experience on using current methods developed for Community Question Answering (cQA) for a commercial application focused on an Italian help desk. Our approach is based on (i) a search engine to retrieve previously answered question candidates and (ii) kernel methods applied to advanced linguistic structures to rerank the most promising candidates. We show that methods developed for cQA work well also when applied to data generated in customer service scenarios, where the user seeks for explanation about products and a database of previously answered questions is available. The experiments with our system demonstrate its suitability for an industrial scenario. In questo articolo, descriviamo la nostra esperienza nell’usare i metodi attualmente disponibili per il Community Question Answering (cQA) in un’applicazione commerciale riguardante il servizio clienti in lingua italiana. Il nostro approccio si basa su (i) un motore di ricerca per recuperare le domande candidate precedentemente risposte e (ii) metodi kernel applicati a strutture linguistiche avanzate per riordinare i candidati più promettenti. Mostriamo che i metodi sviluppati per il cQA funzionano bene anche quando applicati ai dati generati nell’ambito dell’assistenza clienti, dove l’utente cerca informazioni riguardo a dei prodotti e una base di dati di domande precedentemente risposte è disponibile. Gli esperimenti sul nostro sistema dimostrano l’appropriatezza del suo utilizzo in uno scenario industriale.

Abstract

The annual conference CLIC–it (''Italian Conference on Computational Linguistics'') is an initiative of the ''Italian Association of Computational Linguistics'' (AILC – www.ai-lc.it) which is intended to meet the need for a national and international forum for the promotion and dissemination of high-level original research in the field of Computational Linguistics (CL), with particular emphasis on Italian. The volume gathers the Proceedings of the ''Third Italian Conference on Computational Linguistics'' (CLiC–it 2016), held in Naples on 5-6 December 2016. The CLiC–it 2016 papers cover a wide range of topics in the area of computational linguistics and natural language (both written and spoken) processing, by targeting state–of–art theoretical results, experimental methodologies, technologies and application perspectives, and by addressing challenges, open issues and new perspectives related to current and novel trends of the discipline.

Abstract

This paper aims at filling the gap between the accuracy of Italian and English constituency parsing: firstly, we adapt the Bllip parser, i.e., the most accurate constituency parser for English, also known as Charniak parser, for Italian and trained it on the Turin University Treebank (TUT). Secondly, we design a parse reranker based on Support Vector Machines using tree kernels, where the latter can effectively generalize syntactic patterns, requiring little training data for training the model. We show that our approach outperforms the state of the art achieved by the Berkeley parser, improving it from 84.54 to 86.81 in labeled F1. Questo paper mira a colmare il gap di accuratezza tra il constituency parsing dell’Italiano e quello Inglese: come primo miglioramento, abbiamo adattato il parser a costituenti per l’Inglese, Bllip, anche noto come Charniak parser, per l’Italiano e lo abbiamo addestrato sul Turin University Treebank. In seguito, abbiamo progettato un reranker basato sulle Macchine a Vettori di Supporto che usano kernel arborei, i quali possono efficacemente generalizzare pattern sintattici, richiedendo pochi dati di training per addestrare il modello. Il nostro approccio supera lo stato dell’arte ottenuto con il Berkeley parser, migliorando la labeled F1 da 84.54 a 86.81.
