| Abstract | There has been a recent swell of interest in the analysis of blog comments. However, much of the work focuses on detecting comment spam in the blogsphere. An important issue that has been neglected so far is the identification of diversionary comments. Diversionary comments are defined as comments that divert the topic from the original post. A possible purpose is to distract readers from the original topic and draw attention to a new topic. We categorize diversionary comments into five types based on our observations and propose an effective framework to identify and flag them. To the best of our knowledge, the problem of detecting diversionary comments has not been studied so far. We solve the problem in two different ways: (i) rank all comments in descending order of being diversionary and (ii) consider it as a classification problem. Our evaluation on 4,179 comments under 40 different blog posts from Digg and Reddit shows that the proposed method achieves the high mean average precision of 91.9% when the problem is considered as a ranking problem and 84.9% of F-measure as a classification problem. Sensitivity analysis indicates that the effectiveness of the method is stable under different parameter settings. |

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.
