Political Tendency Identification in Twitter using Sentiment Analysis Techniques

This paper describes an approach for political tendency identification of Twitter users. We define some metrics that take into account the polarity of the political entities in the tweets of each user. To obtain this polarities we present the sentiment analysis system developed. The evaluation was performed on the general corpus developed at TASS2013 workshop for Spanish. To our knowledge, the ...

Comparison of Phase-Based 3D Near-Field Source Localization Techniques for UHF RFID

In this paper, we present multiple techniques for phase-based narrowband backscatter tag localization in three-dimensional space with planar antenna arrays or synthetic apertures. Beamformer and MUSIC localization algorithms, known from near-field source localization and direction-of-arrival estimation, are applied to the 3D backscatter scenario and their performance in terms of localization ac...

Design of Passive UHF RFID Tag Antennas Using Metamaterial-Based Structures and Techniques

Metamaterials (Marques et al., 2008; Eleftheriades & Balmain, 2005; Herraiz-Martinez et al. 2009) are one of the many new technologies being adopted to improve the performance of radio frequency identification (RFID) systems (Finkenzeller, 2003; Stupf et al., 2007). In particular, metamaterial-based antenna designs are being used more frequently to improve the read range and reduce the size of ...
