| Abstract | In this work, we consider the continuous computation of correlations between co-occurring tags that appear in messages published in social media streams. The vast amount and pace these messages are created makes it necessary to parallelise the computation of correlations to various nodes in a computing cluster. The main challenge in this is to ensure that each node will compute a subset of the coefficients and every coefficient will be computed by some node. The core task is to continuously create and maintain partitions of the tags and forward the incoming messages based on them. Our approach proposes and evaluates several algorithms that partition the tags to the nodes while at the same time they minimise the replication of tags to the nodes and balance the load on them. The proposed framework is implemented in Java within the Storm stream processing platform. We evaluate the partitioning algorithms and validate the feasibility of our approach through a thorough experimental study performed using real data. |

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.
