However they imply significant performance overheads that need to be carefully considered. Supply Chain Management (SCM) and Traceability systems are an interesting domain for the use of WS technologies that are usually deemed to be too complex and unnecessary in practical applications, especially regarding security. This paper presents an externalized security architecture that uses the eXtensible Access Control Markup Language (XACML) authorization standard to enforce visibility restrictions on trace-ability data in a supply chain where multiple companies collaborate; the performance overheads are assessed by comparing `raw' authorization implementations - Access Control Lists, Tokens, and RDF Assertions - with their XACML-equivalents.","PeriodicalId":431370,"journal":{"name":"2012 Fourth International Conference on Computational Aspects of Social Networks (CASoN)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127686071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing Web services of travel do not consider these constraints. In order to enhance the quality of live (QoL) of elderly people, we propose a pattern Web service, which takes into account these constraints. Our goal consist to use advantage of semantic Web in order to consider fully user constraints and preferences. We present in this paper, a method of collaboration between request, profile and tourism models to elaborate a recommendation system, which allows to select the travel plan according to user ability. This latter is described by the user profile. The models base on the semantic description of all: user profile, user request and tourism data base. In addition, both of existed user profile ontology and tourism ontology have to be extended to consider constraints and preferences of elderly people.","PeriodicalId":431370,"journal":{"name":"2012 Fourth International Conference on Computational Aspects of Social Networks (CASoN)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127943908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, this proposal includes a methodology for transforming basic, and sometimes unstructured, payroll data into useful information for taking decisions regarding irregularities within the payroll auditing process. By means of its implementation as a business intelligence application, the proposal is validated using the original data generated in the monthly payroll analysis of the Brazilian public sector employees.

Unfortunately, there is a category of attacks that seriously threatens the continuity of wireless networks: the jamming attack. The open nature of wireless mediums makes them vulnerable to any wireless capable devices. However, there have not been any studies that address the issue of how the service providers should deploy its topology or allocate its resources to minimize the impact of jamming attacks launched by malicious attackers. In this paper, a mathematical model formulating an attack-defense scenario of the problem is proposed. The results show when deploying defense resources, considering hops from the core node is more useful than link degrees. With the advantage of simulations, the concept of incomplete information can be taken into account which, while increasing the difficulty of the problem, makes the problem closer to reality.","PeriodicalId":431370,"journal":{"name":"2012 Fourth International Conference on Computational Aspects of Social Networks (CASoN)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131968760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A recent branch of sociology, the Actor-Network Theory or ANT, states that relations among human and nonhuman actors are equally important to comprehend social phenomena. Since scientists are potential users of huge computational support, their communities provide relevant cases for domain characterization and software design. This paper investigates the possibilities of using ANT to characterize a real instance of those social networks. The active role of nonhuman actors allows us to trace the relations based on material clues left behind by the actors, and also to bring forth features to be explored by social software. The results of this study present a graphical representation that allows quantitative and qualitative analysis of the social network, which may inform a better design of systems for those communities.","PeriodicalId":431370,"journal":{"name":"2012 Fourth International Conference on Computational Aspects of Social Networks (CASoN)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124592227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It allows also a continuous integration and enhancement of different types of research artefacts including visual models, software and scripts. RMC extends traditional collaborative platforms by means of a scientific research-oriented social layer which allows intensive user contribution, interactions, and community building along with a content management system that lets researchers share, evaluate and develop valuable knowledge.

Classification of web page content can improve the quality of web search and its accuracy. Unfortunately the high dimensionality of the web pages dataset has made the process of classification difficult. The use of an automatic method for web page classification can simplify the whole process and assist the search engine in getting more relevant results. Nowadays information on the web is generally structured and formatted in a not formal way. This absence of semantics leads to create formal methods to provide more semantics information into web page. Search engines including Bing, Google, Yahoo! and Yandex formed collection of schemas Schema.org to support web page semantics and improve their search results. This paper explores the use of formal source code structure for classifying a large collection of the web content.
