Clustering data streams is equally important and difficult because of the numerous hurdles attached to it. A number of algorithms have been proposed to offer solutions for efficient clustering. Grid-based clustering approach was adopted few years ago to overcome the limitations of conventional partition-based algorithms for data stream clustering. Data points are mapped to the grid-cells to form micro-clusters which later are used for clustering. Using density in the clustering process is proved to be a remarkable success and in recent years many researchers have used density to find arbitrary shaped & density clusters and identify outliers. Concept of density-based clustering is to use grid-based clustering at core and create a distinction between dense and sparse grids using density threshold values and use dense grids to yield clustering results; which provide more cluster purity and accuracy. In this paper, we reviewed grid-based data stream clustering algorithms which utilize density. We evaluated their functionalities and identified their limitations. In the end, we critically evaluated different aspects of algorithms and suggested one of these algorithms which is better in terms of performance and accuracy.","PeriodicalId":146662,"journal":{"name":"2016 Eleventh International Conference on Digital Information Management (ICDIM)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123973250","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 do this by analyzing a corpus of CSR reports produced by 7 US firms (Citi, Coca-Cola, Exxon-Mobil, General Motors, Intel, McDonald's and Microsoft) in 2004, 2008 and 2012, and focusing on a reduced set of vectors — or Singular Vector Decompositions (SVDs)-derived from these CSR reports while exploring term associations (Text Topics or Term Clusters). Specifically, we use centroid clustering on these SVDs to identify centroid-guiding-CSR-report-components (or firms with prominent voices and prevalent discourses around a CSR topic). The analysis is performed by year in order to discern the way in which prominent voices and prevalent discourses (around CSR topics) have evolved through time. Results indicate that it is difficult for firms to maintain a prominent voice around CSR issues through time, and that when they manage to do so it is because the prevalent discourse has direct business implications.","PeriodicalId":146662,"journal":{"name":"2016 Eleventh International Conference on Digital Information Management (ICDIM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122032634","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}

Those systems have been present in the daily lives of countless people helping them to share personal experiences, expectations and opinions. So high popularity has made of such networks complex systems. To understand the operation and phenomena that occur in such networks, there are metrics and models that capture aspects of their structures. The purpose of this work is to understand the complex reality of eBay e-commerce network, their connections and the dynamics of its users. Data were collected using a Web crawler developed in this work, and it resulted in a database of approximately 87 million transactions and 15 million different dealer users. From these data, the characterization was made estimating network metrics, like dealer users' degree distribution, that gave us key insights about the eBay negotiation network. We found that there are users who bought/sold for more than 100.000 different persons. We also found that a user A interacted over 4.000 times with another user B in just 3 months. Those and other interesting results, such as average distance and feedbacks ratings, were obtained, analyzed and discussed in this work.","PeriodicalId":146662,"journal":{"name":"2016 Eleventh International Conference on Digital Information Management (ICDIM)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127651924","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}

Its inception has changed the ways businesses are done today in a competitive environment. In order to get value from significant investments done on complex IT infrastructure, it should be efficiently governed and managed. IT governance and management is a part of overall corporate governance and management and plays a vital role in aligning IT with business strategies. Among the several frameworks proposed for IT governance, COBIT is the most comprehensive and diverse framework providing support for both governance and management at all levels in multiple business domains. COBIT provides a toolset to bridge the gap between control requirements, technical issues and business risks. In this study we provide a survey of a few implementations of COBIT framework in multiple domains. Based on the survey we state our findings and recommend its adoption to comprehend similar issues. Further we identified certain limitations of COBIT framework and addressed the integration of service life cycle management into the original framework. We added seven new processes to the process structure of COBIT 5 along with their high level objectives. Also we added a few control objectives to the existing processes of COBIT framework. The survey provides a clear understanding of each COBIT implementation and the elements of the framework addressed in each implementation. Our study serves as a guide for all COBIT implementers and helps them teach how to deal with different kinds of governance or management matters. Further how the framework can be enhanced to provide service life cycle management.","PeriodicalId":146662,"journal":{"name":"2016 Eleventh International Conference on Digital Information Management (ICDIM)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129974203","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}

Skillful sharing of the intentions of search and their results is quite important to enable collaborative exploration to be smoothly conducted. However, such sharing is usually difficult for members since they often face difficulties in expressing search intentions into queries and suffer from the troublesome activity of page selection. Such problems become more serious for novices. In particular, it is important but difficult to sufficiently understand the differences between search intentions and actual browsing situations. Moreover, there is often insufficient mutual understanding of differences in search policies between members of collaborative exploration since they tend to superficially confirm the search results. This research was aimed at developing novel support to cultivate the consideration skill of search strategy focusing on the novices' understanding of search contexts. This paper mainly describes the framework of support methods and provides a system overview. This paper also discusses the basic effectiveness and characteristics of our methods based on the results obtained from an experiment.","PeriodicalId":146662,"journal":{"name":"2016 Eleventh International Conference on Digital Information Management (ICDIM)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125149453","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}
