Abstract | Sometimes, during a search task users may switch from one search engine to another for several reasons, e.g., dissatisfaction with the current search results or desire for broader topic coverage. Detecting the fact of switching is difficult but important for understanding users' satisfaction with the search engine and the complexity of their search tasks, leading to economic significance for search providers. Previous research on switching detection mainly focused on studying different signals useful for the task and particular reasons for switching. Although it is known that switching is a personal choice of a user and different users have different search behavior, little has been done to understand how these differences could be used for switching detection. In this paper we study the effectiveness of learning personal behavior patterns for switching detection and present a personalized approach which uses user's session history containing sessions with and without switches. Experiments show that users' personal habits and behavior patterns are indeed among the most informative signals. Our findings can be used by a search log analyzer for engine switching detection and potentially other log mining problems, thus providing valuable signals for search providers to improve user experience. |

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.
