In this paper we report on the activity of the project Computational Processing of Portuguese (Processamento computacional do português) in what concerns providing access to Portuguese corpora through the Internet. One of its activities, the AC/DC project (Acesso a corpora/Disponibilização de Corpora, roughly "Access and Availability of Corpora") allows a user to query around 40 million words o...

The goal of this paper is to describe significant corpora available to support speaker recognition research and evaluation, along with details about the corpora collection and design. We describe the attributes of high-quality speaker recognition corpora. Considerations of the application, domain, and performance metrics are also discussed. Additionally, a literature survey of corpora used in s...

This paper studies the problem of mining named entity translations from comparable corpora with some “asymmetry”. Unlike the previous approaches relying on the “symmetry” found in parallel corpora, the proposed method is tolerant to asymmetry often found in comparable corpora, by distinguishing different semantics of relations of entity pairs to selectively propagate seed entity translations on...

Since corpus-based natural language processing has to deal with large corpora, efficient searching of the large corpora is inevitably necessary. For example, one might want to examine how a word or a phrase is used in the large corpora or to collect frequencies of all terms in the large corpora. Our system Sary solves these problems by providing fast full-text search facilities for a single lar...

In th is paper, w e in troduce our corpora under developm ent, w hich are recorded in a real environm ent. These corpora com prise dialogues collected in hospitals w ith the aim of developing a nursing serv ice support system through a com prehensive understanding of nursing activ ities. We use the corpora to analyze how nurses perform their nursing duties and how they express the perform ance ...
