| Abstract | Graphs are adept at describing relational data, hence their popularity in fields including network management, Webpage analysis and sociology. However, most of the current graph mining work regards graphs as static and unchanging, even though many graphs are dynamic. In this paper, we introduce a new pattern to discover from evolving graphs, namely regions of the graph that are evolving in a correlated manner. These regions of correlated spatio-temporal change group together graph changes that are topologically near (spatial) and evolve similarly (temporal) to each other. The regions can be used to summarise changes, particularly for graphs that have many simultaneous changes. We have developed an algorithm called cSTAG to summarise changes in dynamic graphs. This new algorithm discovers these regions of correlated change and identifies events that caused these changes. As a demonstration of the effectiveness of our algorithm, we applied cSTAG to summarise the changes to the border gateway protocol connectivity graph during the 2005 Hurricane Katrina disaster. cSTAG was able to identify the reported failures in Louisiana, as well as other simultaneous events |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
