| Abstract | Situation awareness (SA) has been well recognized as a critical yet often elusive foundation for effective group decision-making. The task of identifying and understanding dynamic, evolving discussion situation can be quite challenging, especially when coping with information overload and time pressure. With the wide adoption of collaborative software in support of group collaboration, there has been exponential growth of online group discussion. As a result, the traditional thread-based hierarchical structure and presentation of group messages become ineffective in support of real-time SA, which may affect the process and outcome of group collaboration. To address this important problem, in this study, we propose a novel visualization-based approach to supporting users' SA in online group discussion and decision making. We have also developed a set of new variables to measure SA in online group discussion from three key aspects: discussion snapshot, discussion evolution, and people. The proposed approach was empirically evaluated by using a prototype system and discussion data collected from an online group discussion session. The results show that the proposed approach significantly improves user performance and perception of SA in group discussion. The findings of this study provide significant research contributions and practical implications for the design and use of situation-aware collaborative software. |

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.
