Participación de SINAI DW2Vec en TASS 2015

This paper introduces the polarity classification system used by the SINAI-DW2Vec team for the task 1 at the TASS 2015 workshop. Our approach does not follow the Vector Space Model nor applies syntactic or lexical analyses. This solution is based on a supervised learning algorithm over vectors resulting from concatenating two different weighted vectors. Those vectors are computed using two diff...

Participación de SINAI en TASS 2016

This paper introduces the polarity classification system used by the SI-NAI team for the task 1 at the TASS 2016 workshop. Our approach is based on a supervised learning algorithm over vectors resulting from a weighted vector. This vector is computed using a deep-learning algorithm called Word2Vec. The algorithm is applied so as to generate a word vector from a deep neural net trained over a sp...

Mapeamento Participativo de Opiniões sobre o Uso de Dinheiro Público

Recent surveys show dissatisfaction of the population with politicians and their representatives. This paper describes a technological tool developed to provide a communication channel between citizens and policy makers. This tool allows to make reports like the lack of investment and waste of public resources, and highlight initiatives which has society approval. The reports will be georeferen...

Avaliação Empírica de Técnicas de Comparação Privada Aplicadas na Resolução de Entidades

Privacy-Preserving Record Linkage (PPRL) consists in identifying which records in two or more databases correspond to the same entity. In this context, different private data comparison techniques have been used, e.g., Bloom filters. However, Bloom filters do not perform well when numeric data or dates are compared. This work aims to evaluate if Homomorphic Asymmetric Cryptography (HAC) can imp...
