Their steady increase reveals a trend towards a more dynamic and interactive space, in which users can individually assign terms to online resources. Even though users find tagging easy to use and understand, they need to see, closely, users sharing same interest as them for many reasons (facilitating the information retrieval and confidentiality management, insuring privacy respect, etc.). In this paper, we introduce a new method for automatically creating a new social network, across a popular folksonomy site, where users are clustered according to their domain of interest. We semantically represent these interests by using DBPEDIA ontology as a multi-domain ontology and we propose a methodology for enriching this ontology.","PeriodicalId":342597,"journal":{"name":"2011 International Conference on Computational Aspects of Social Networks (CASoN)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123654769","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}

The following scenario is considered. Suppose that user Alice thinks that Bob might be a good new friend. So, Alice and the Online Social Network (representing Bob) engage in a two-party matching protocol. In this protocol no work from Bob is required, Bob can be offline. The matching protocol is designed to give Alice an indication if Bob is similar to her based on their profiles. We show that the process does so without revealing the private information of Alice and Bob to one another and to the Online Social Network.","PeriodicalId":342597,"journal":{"name":"2011 International Conference on Computational Aspects of Social Networks (CASoN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128690691","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}

Furthermore, with the purpose of assessing interface adaptation to user's needs and preferences, search usability is also studied.

Social networks can provide a wealth of information about behavioral patterns of individuals and groups, and can be successfully deployed to identify individuals or anomalous groups engaged in unlawful activities. Most of the tools at analysts' disposal today employ state of the art visual and statistical techniques using which they explore the data to identify potential regions of interest within a vast network and gradually zero-in on targets. However, reusing this knowledge to find approximately similar patterns in the same or another network requires going through the same process all over again. In this paper, we present an efficient searching mechanism for automated detection of approximately similar patterns which not only exhibit similar structure but also have similar attributes. We show that the proposed methods can help analysis of large social networks much more efficiently than pure visual techniques.","PeriodicalId":342597,"journal":{"name":"2011 International Conference on Computational Aspects of Social Networks (CASoN)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132671285","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}

Depending on their motivation and the resulting hypothesis, they usually focus on one of these two structural properties, leaving the other aspect aside. In this paper we investigate the relation between structural centralization, which follows a core/periphery model, and structural clustering, which is given by more or less disjoint cohesive groups. We present our concept of Group Adjacency Matrices for graphical evaluations of such structures, and analyze these properties in networks of top blogs in six different languages. We show that the two properties are present in parallel in our datasets, making the respective identification more difficult. We want to raise awareness of this potential issue, and demonstrate that the knowledge about the clustering structure in a network can be utilized to make the analysis of the core/periphery structure more reliable.","PeriodicalId":342597,"journal":{"name":"2011 International Conference on Computational Aspects of Social Networks (CASoN)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123087651","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}

In order to obtain in-depth understanding of such phenomenon, we employed a qualitative research methodology. We conducted semi-structured interviews with twenty-two (22) managers (from middle to high level) working in government link corporations (GLCs) and multinational corporations (MNCs). We found that there were distinctive intercultural communicative behaviors, all rooted in their diverse cultural values, beliefs, and attitudes.

Product codes provide a good code rate as well as a good BER performance. Moreover, they have a brute power to correct burst errors, which are very harmful in digital transmission. It is because product codes are correct row-wise as well as column-wise. Conventional iterative decoding algorithm initially proposed by Al-Askary based upon Maximum Likelihood (ML) scheme, has a huge complexity which is unaffordable for long codes used in real time transmissions. MIDA being a sub-optimum algorithm reduces its complexity in an efficient way by utilizing the basic idea of Syndrome Decoding of Linear Block Codes. So decoding becomes more efficient also the complexity reduction factor increases with each iteration. The worst case complexity of MIDA is closed to that of conventional algorithm but in average case there is huge reduction in complexity, with negligible performance degradation.","PeriodicalId":342597,"journal":{"name":"2011 International Conference on Computational Aspects of Social Networks (CASoN)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116149266","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}

We discuss the development and implementation of this strategy starting from an evaluation of the use and needs of social media of students, professors and other university staff. This survey provides the basis for the requirements analysis for a platform for internal and external communication, whose structure is presented here.
