“…This is due to the fact that the security measures are primarily concerned with unsolicited bulk messages and not against software entities behaving like normal users. Generally speaking, given the high percentage of users connected participating in OSN activities, it is easy to collect information about persons, even in an automated manner, with batch procedures, through web spiders (Gupta and Johari, 2009) and software agents (Bodorik and Jutla, 2008).…”

Social environments were already present in the original web vision, but nowadays are mainly available through online social networks (OSNs), which are a real cultural phenomenon. However, their actual deployment is very heterogeneous, reflecting into different development choices and functional architectures. Such aspects, jointly with the intrinsic sharing of personal information, lead to severe risks both in terms of security and privacy. In this perspective, our work proposes a taxonomy-based approach to describe and model the complex security space characterising OSNs. The contributions of this paper are: 1) to introduce a systematic approach to define the 'problem space' of an OSN; 2) to showcase basic models for organising the engineering and the needed checking procedures.Reference to this paper should be made as follows: Caviglione, L., Coccoli, M. and Merlo, A.

“…El objetivo principal de un Web crawler es proporcionar datos actualizados a un motor de búsqueda [36]. Son utilizados principalmente para crear una copia de todas las páginas rastreadas para su posterior procesamiento por un motor de búsqueda luego de ser indexadas para proporcionar resultados de una forma rápida [37].…”

<p>La información disponible en redes de datos como la Web o las redes sociales se encuentra en continuo crecimiento, con unas características de dinamismo especiales. Entre los mecanismos encargados de rastrear los cambios en dicha información se encuentran los Web<br />crawlers, los cuales por la misma dinámica de la información, deben mejorarse constantemente en busca de algoritmos más eficientes. Este documento presenta el estado actual de los algoritmos de rastreo de la Web, sus tendencias, avances, y nuevos enfoques dentro del contexto de la dinámica de las redes sociales.</p>

“…They read and parse Web pages, and then move to hyper links on these pages, looking for more pages to process. The performance of Web crawlers is based on their selection policy, revisit policy, politeness policy, and parallelization policy (Gupta and Johari, 2009;Peisu et al, 2008).…”

Various initiatives designed to increase Arabic Web content have been undertaken in recent years, and now search engines are reporting that the Arabic portion of Web content has grown relative to the overall Web content. An accurate estimate of Arabic Web content is crucial for those interested in studying it and enriching it. In this paper, we propose a statistics-based system to estimate the size of Arabic indexed Web content using three popular search engines; Google, Yahoo and Bing. Our system relies on selecting sample words from an Arabic corpus to estimate the size of the Arabic Web content indexed by the search engines and the overlap among them. We have used Arabic Wikipedia as a corpus, as it provides diversified content accessed by a large number of Internet users. Our results show that, as of December 2010, the size of the Arabic indexed Web content was estimated at 2 to 2.1 billion pages.
