This paper describes the output of a study to tackle the problem of gang-related crime in the UK; we present the intelligence and routinely gathered data available to a UK regional police force, and describe an initial social network analysis of gangs in the Greater Manchester area of the UK between 2000–2006. By applying social network analysis techniques, we attempt to detect the birth of two new...
Wildfire is a significant hazard for sensitive areas, i.e. geographic regions where urban communities, installations for processing or storing hazardous chemical substances, valuable assets and monuments, or other important infrastructure meet or intermix with fire-prone wildlands. To avoid human casualties, organized evacuation of the population should be examined as a measure to be appropriately...
Social Networks are the common platform for the present generations to share ideas. The members of these sites have grown to billions in the last decade and much more at present. In this paper, the metrics Page Rank, Path Length, Clustering Coefficient and Vertex Degree for SNWSs are evaluated by users' database of Facebook. The results indicate that the metrics Page Ranking, Path Length and Vertex...
It is stated that the students complain about the online learning environments mostly because of the sense of being isolated. Belonging to a community is one of the critical variables for online learning environments. Many studies on the online learning community have been conducted around the world. This research aimed to analyze the studies according to variable frequency, work group, data collection...
The Mining Software Repositories community typically focuses on data from software configuration management tools, mailing lists, and bug tracking repositories to uncover interesting and actionable information about the evolution of software systems. However, the techniques employed and the challenges faced when mining are not restricted to these types of repositories. In this paper, we present an...
Automated regression testing is often crucial in order to maintain the quality of a continuously evolving software system. However, in many cases regression test suites tend to grow too large to be suitable for full re-execution at each change of the software. In this case selective retesting can be applied to reduce the testing cost while maintaining similar defect detection capability. One of the...
There are many online communities with member-generated and openly available multimedia content. Their success depends on having active contributing users and on producing useful content. With this criterion, the community of sound practitioners that has emerged in Freesound is a successful case of interest to be studied. But to understand it and support it further we need an appropriate analysis...
We provide an overview of the current data management research issues in the context of the Semantic Web. The objective is to introduce the audience into the area of the Semantic Web, and to highlight the fact that the area provides many interesting research opportunities for the data management community. A new model, the Resource Description Framework (RDF), coupled with a new query language, called...
Traditional clustering algorithms identify just a single clustering of the data. Today's complex data, however, allow multiple interpretations leading to several valid groupings hidden in different views of the database. Each of these multiple clustering solutions is valuable and interesting as different perspectives on the same data and several meaningful groupings for each object are given. Especially...
While ICDM has traditionally enjoyed an unusually high quality of reviewing, there is no doubt that publishing in ICDM is very challenging. In this tutorial Dr. Keogh will demonstrate some simple ideas to enhance the probability of success in getting your paper published in a top data mining conference, and after the work is published, getting it highly cited.
Developers of open source projects are distributed across the world. They rely on email, mailing lists, instant messaging, IRC channels and more recently IRC meetings to communicate. Most of the studies thus far focus on the use of mailing lists by OSS developers, however, an increasing number of open source projects are using IRC meetings to hold developer meetings. In this paper, we mine the #gtk-devel...
Conferences are an important environment for academic knowledge exchange, and are valued by researchers as a good way to increase ones social network and meet potential collaborators. The question we investigate in this work is whether conferences actually influence collaboration between researchers, providing a starting point for joint work. To conduct this investigation, we used the DBLP database...
Semantic web services have received a significant amount of research attention in the last years but too little effort has been put into the evaluation of the approaches so far. The main blocker of thorough evaluations is the lack of large and diverse test collections for semantic web services. In this demo we present a portal designed to help working towards common test collections by making it easy...
