This research addresses the computationally-effective implementation of cryptographic protocols based on elliptic curves, and targets in particular cryptosystems that should be hosted on embedded programmable processors. In principle, the implementation of Elliptic Curve Cryptography (ECC) requires one to deal with different design options, which stem from the available degrees of freedom: elliptic...

The paper presents a general methodology to implement a flexible Focused Crawler for investigation purposes, monitoring, and Open Source Intelligence (OSINT). The resulting tool is specifically aimed to fit the operational requirements of law-enforcement agencies and intelligence analyst. The architecture of the semantic Focused Crawler features static flexibility in the definition of desired concepts,...
The automatic detection of orientation and emotions in texts is becoming increasingly important in the Web 2.0 scenario. There is a considerable need for innovative techniques and tools capable of identifying and detecting the attitude of unstructured text. The paper tackles two crucial aspects of the sentiment classification problem: first, the computational complexity of the deployed framework;...
The paper addresses some roles of concept-based representations in document clustering to support knowledge discovery. Computational Intelligence algorithms can benefit from semantic networks in the definition of similarity between pairs of documents. After analyzing the tuning of semantic networks in a systematic fashion, the research defines and evaluates a novel semantic-based metrics, which integrates...
