Using a Dialogue Manager to Improve Semantic Web Search

Question Answering systems that resort to the Semantic Web as a knowledge base can go well beyond the usual matching words in documents and, preferably, find a precise answer, without requiring user help to interpret the documents returned. In this paper, the authors introduce a Dialogue Manager that, through the analysis of the question and the type of expected answer, provides accurate answers to the questions posed in Natural Language. The Dialogue Manager not only represents the semantics of the questions, but also represents the structure of the discourse, including the user intentions and the questions context, adding the ability to deal with multiple answers and providing justified answers. The authors’ system performance is evaluated by comparing with similar question answering systems. Although the test suite is slight dimension, the results obtained are very promising.

Improving understandability in consumer health information search: Uevora @ 2016 fire chis

This paper presents our work at 2016 FIRE CHIS. Given a CHIS query and a document associated with that query, the task is to classify the sentences in the document as relevant to the query or not; and further classify the relevant sentences to be supporting, neutral or opposing to the claim made in the query. In this paper, we present two different approaches to do the classification. With the first approach, we implement two models to satisfy the task. We first implement an information retrieval model to retrieve the sentences that are relevant to the query; and then we use supervised learning method to train a classification model to classify the relevant sentences into support, oppose or neutral. With the second approach, we only use machine learning techniques to learn a model and classify the sentences into four classes (relevant & support, relevant & neutral, relevant & oppose, irrelevant & neutral). Our submission for CHIS uses the first approach.

O controlo do circuito, da tramitação, da recuperação dos documentos e a legislação nos arquivos municipais de Moçambique

Este estudo tem como objectivo conciliar aspectos da Arquivística à Boa Administração através da gestão dos documentos com efoque no controlo do circuito, da tramitação, da recuperação dos documentos e a legislação nos arquivos municipais em Moçambique no período 1933-2007. O estudo realizado em três universos: municípios de Maputo, da Beira e de Quelimane, em que se confirma que os instrumentos de controlo utilizados na circulação e recuperação dos documentos contribuem para uma boa governação, garantindo a transparência dos actos administrativos e a salvaguarda dos direitos dos cidadãos. Mostra-se que nunca se deve prescindir quer das actividades que delineiam os macro e micro processos nas instituições quer da definição prévia dos percursos documentais, da regulamentação dos procedimentos, da utilização de técnicas que permitam a recuperação dos documentos e da informação: Mostra-se a importância da formação e do conhecimento dos procedimentos pelos funcionários dos escalões autorizados a realizar, pareceres e despachos, da determinação das formas do controlo documental e da garantia no cumprimento dos prazos estabelecidos para cada percurso e, finalmente, a necessária observância prática da legislação criada para esse efeito. ABSTRACT; This case study has as a main objective the reconciliation of the filing aspects with a good Administration though the management of documents and its network, specially in the restoring of files and its legislation into the Municipal Archives of Mozambique during the period of 1933-2007. The study was based on three cities where municipal councils were created, namely: Maputo, Beira and Quelimane. Record's contrail tools used either for registering record transactions or for the access of information contained in them, ensure good governance, transparency and protection of citizen rights. We show the necessity of the activities which lead to macro and micro processes within the organization. This requires that records procedures on transactions must be established and so the guidelines for records' contrail, registration and tools for the information retrieval. We indicate procedures to be followed by authorized civil servants, the importance of their practical training and we define types of records' contrail to ensure their preservation and use in order to accomplish the national legislation.
