| Abstract | Focus+Context is a popular and effective technique for graph exploration. While previous works concentrate on studying how to display focal nodes with a single context, we argue that it is often difficult to select an optimal context for a complex graph exploration task in practice. In this paper, we propose Multi-Con, a technique to allow users viewing multiple contexts to explore graphs more effectively and efficiently. Our idea is to let users define multiple contexts to reveal different aspects of the graph and enable users to switch between these contexts quickly and interactively in a single view during exploration. Multi-Con provides two key features to ensure the effectiveness and efficiency when using multiple contexts for graph exploration. First, it can achieve good legibility when displaying foci with each context in limited viewing space. In addition, it allows users to switch between contexts smoothly and quickly. We have conducted a case study with social network data extracted from paper authorship relations on three major conferences in computer architecture and systems areas. The results have shown that Multi-Con can help users quickly learn the relationship between foci and the rest of the network in multiple aspects. |

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.
