| Abstract | The purpose of this study was to analyze the characteristics of traffic information propagation via Twitter using a keyword analysis and a network analysis. For the keyword analysis, the main contents of Twitter messages were identified using a TF-IDF (Term Frequency - Inverse Document Frequency) model. For the network analysis, the network connectivity among Twitter users, including Traffic Information Producers (TIPs), Opinion Leaders (OLs), and their followers were measured by estimating the densities and mean distances in their follow networks. Based on the keyword analysis result, the words representing traffic conditions were revealed as the most influential keywords. In addition, the information regarding traffic accident occurrences was found to be most frequently retweeted. As a result of the network analysis, MBC news which is one of the biggest newscasts in Korea showed the greatest connectivity among TIPs. OLs proved more powerful in information propagation than TIPs. Conclusively, there is an apparent demand for establishing strategies to propagate traffic information based on the characteristics of Twitter in a more efficient manner. |

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.
