Due to the growing use of biometric technologies in our modern society, spoofing attacks are becoming a serious concern. Many solutions have been proposed detect fake "fingerprints" on an acquisition device. In this paper, we propose take advantage intrinsic features friction ridge skin: pores. The aim study is investigate potential using pores attacks. Results show that promising approach. Four major observations were made: First, results confirmed reproduction possible. Second,...

The lack of explicit semantics in the current Web can lead to ambiguity problems: for example, search engines return unwanted information since they do not take into account exact meaning given by user keywords used. Though disambiguation is a very well-known problem Natural Language Processing and other domains, traditional methods are flexible enough work Web-based context.In this paper we have identified some desirable properties that Web-oriented method should fulfill, make proposal...

International organizations (e.g., FAO, WHO, etc.) are increasingly expressing the need for multilingual ontologies different purposes, e.g., ontology-based machine translation, information retrieval. However, most of built so far have mainly English or another natural language as basis. Since ontology building is a very expensive and time-consuming undertaking, we propose methods guiding users in localization ontologies, provide tools supporting process. The main contributions this paper...

We revisit the notion of ontology localization, propose a new definition and clearly specify layers an that can be affected by process localizing it. also work out number dimensions allow to characterize type localization performed predict will affected. Overall our aim is contribute better understanding task ontology.

The Magallanes fold and thrust belt (FTB) presents a large-scale curvature from N-S oriented structures north of 52°S to nearly E-W in Tierra del Fuego Island. We present paleomagnetic anisotropy magnetic susceptibility (AMS) study 85 sites sampled Cretaceous Miocene marine sediments. Magnetic is lower than 0.0005 SI for 76 mainly controlled by paramagnetic minerals. AMS results indicate that the sedimentary fabric preserved undeformed areas more external sheets units, where an incipient...

Resumen: En un entorno abierto como la Web, no es posible estandarizar los procesos de descripción y publicación metadatos, cada institución puede manejar diferentes formatos o modelos datos.Para mejorar interoperabilidad semántica entre repositorios heterogéneos, se están adoptando enfoques basados en tecnologías Web Semántica; esta manera, Librería Digital conservar sus cualidades locales específicas requerirá resignarlas para poder normalizar el intercambio, reuso cosecha recursos...

Searching for scientific publications online is an essential task researchers working on a certain topic. However, the extremely large amount of found in web turns process finding publication into very difficult whereas, locating peers interested collaborating specific topic or reviewing literature even more challenging. In this paper, we propose novel architecture to join multiple bibliographic sources, with aim identifying common research areas and potential collaboration networks, through...

The advance of technology makes that mobile devices have gained widespread popularity. Modern include build in sensors, cameras, compasses, and enhanced storage processing capabilities, allowing developers to use those features create applications with new or functionality. In this context, we present a application for searching places, people events within university campus. our work, leverage semantic web augmented reality provide an high degree query expressiveness user experience....

Electronic Program Guides (EPGs) describe broadcast programming information provided by TV stations. However, users may obtain more when these guides have been enriched. The main contribution of this work is to present an automation process for EPG's enrichment through the use semantic technologies and external resources. Among several resources involved in process, following can be mentioned : ontologies, web services, repositories natural language processing techniques.

This paper proposes a general framework that allows to identify video in real time using perceptual image hashing algorithms. In order evaluate the versatility and performance of framework, it was coupled for use case about ads tv monitoring. Four Perceptual Image Hashing (PIH) algorithms were subject benchmarking process best one case. focused on analyze differences terms discriminability (D), robustness (R), processing (Tp) efficiency (E). A truth table used obtain information robustness,...

Currently, institutions store the information that they produce in digital repositories, especially those within academic scope, such as universities and libraries. However, lack of agreement defining protocols, meta-data descriptions technologies for publication has caused issues while trying to integrate repositories. Numerous alternatives have been proposed tackle this problem, however, most them are based on syntactical technologies, which exclusive ambit hampering a higher level...

Compared to analog transmissions, Digital Television (DTV) standards allows a higher number of available TV stations and consequently, larger entertainment offer. In this context, Recommender Systems (RS) support users in choosing content by narrowing their options reduced set based on preferences an interests. However, new or those having incomplete profiles prevent the system produce accurate recommendations, which is more noticeable early stages RS. This paper proposes use demographic...

The aim of semantic web is to provide meaning data shared by a network, therefore making it readable humans and computer applications. objective this give the information services well-defined tagging content with machine processable descriptions. Within there are annotations, which relate classes offering structured data. In addition, an ontology essential part web, because provides vocabulary terms includes properties between concepts. There several proposals over annotations included in...
