Abstract

EVALITA is a periodic evaluation campaign of Natural Language Processing (NLP) and speech tools for the Italian language. The general objective of EVALITA is to promote the development of language and speech technologies for the Italian language, providing a shared framework where different systems and approaches can be evaluated in a consistent manner. The diffusion of shared tasks and shared evaluation practices is a crucial step towards the development of resources and tools for NLP and speech sciences. The good response obtained by EVALITA, both in the number of participants and in the quality of results, showed that it is worth pursuing such goals for the Italian language. As a side effect of the evaluation campaign, both training and test data are available to the scientific community as benchmarks for future improvements. EVALITA is an initiative of the Italian Association for Computational Linguistics (AILC) and it is endorsed by the Italian Association for Artificial Intelligence (AI*IA) and the Italian Association for Speech Sciences (AISV).

Abstract

This paper describes our UO_IRO system developed for participating in the shared task IronITA, organized within EVALITA: 2018 Workshop. Our approach is based on a deep learning model informed with linguistic knowledge. Specifically, a Convolutional (CNN) and Long Short Term Memory (LSTM) neural network are ensembled, also, the model is informed with linguistics information incorporated through its second to last hidden layer. Results achieved by our system are encouraged, however a more fine-tuned hyper-parameters setting is required for improving the model’s effectiveness. Questo articolo descrive il nostro sistema UO_IRO, sviluppato per la partecipazione allo shared task IronITA, presso EVALITA 2018. Il nostro approccio si basa su un modello di deep learning con conoscenza linguistica. In particolare: una Convolutional Neural Network (CNN) e una Long Short Term Memory Neural Network (LSTM). Inoltre, il modello è arricchito da conoscenza linguistica, incorporata nel penultimo hidden layer del modello. Sebbene sia necessario un miglioramento a grana fine dei parametri per migliorare le prestazioni del modello, i risultati ottenuti sono incoraggianti.

31. Document Representation Using Global Association Distance Model.

Abstract

Text information processing depends critically on the proper representation of documents. Traditional models, like the vector space model, have significant limitations because they do not consider semantic relations amongst terms. In this paper we analyze a document representation using the association graph scheme and present a new approach called Global Association Distance Model (GADM). At the end, we compare GADM using K-NN classifier with the classical vector space model and the association graph model. [ABSTRACT FROM AUTHOR]

Abstract

In this paper we present a new model, designated as association graph, to improve document representation, facilitating the ontological dimension. We explain how to create and use this kind of graph. Also, we analyze a document similarity measure based on this representation. A classical vector space model was used to evaluate this model and the similarity measure, investigating their strengths and weaknesses. The proposed model was found to give promising results.
