| Abstract | Protecting our nation's infrastructure and securing sensitive information are critical challenges for both industry and government. Due to the complex and diverse nature of the environments which can expose attacks or terrorism activity, one must not only be able to deal with attacks that are dynamic, or constantly changing, but also take into account the structural aspects of the networks and the relationships among communication events. However, analyzing a massive, ever-growing graph will quickly overwhelm currently-available computing resources. One potential solution to the issue of handling very large graphs is to handle data as a “stream”. In this work, we present an approach to processing a stream of changes to the graph in order to efficiently identify any changes in the normative patterns and any changes in the anomalies to these normative patterns without processing all previous data. The overall framework of our approach is called PLADS for Pattern Learning and Anomaly Detection in Streams. We evaluate our approach on a dataset that represents people movements and actions, as well as a scalable, streaming data generator that represents social network behaviors, in order to assess the ability to efficiently detect known anomalies. |

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.
