| Abstract | We present two studies that evaluate the accuracy of human responses to an intelligent agent's data classification questions. Prior work has shown that agents can elicit accurate human responses, but the applications vary widely in the data features and prediction information they provide to the labelers when asking for help. In an initial analysis of this work, we found the five most popular features, namely uncertainty, amount and level of context, prediction of an answer, and request for user feedback. We propose that there is a set of these data features and prediction information that maximizes the accuracy of labeler responses. In our first study, we compare accuracy of users of an activity recognizer labeling their own data across the dimensions. In the second study, participants were asked to classify a stranger's emails into folders and strangers' work activities by interruptibility. We compared the accuracy of the responses to the users' self-reports across the same five dimensions. We found very similar combinations of information (for users and strangers) that led to very accurate responses as well as more feedback that the agents could use to refine their predictions. We use these results for insight into the information that help labelers the most. |

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.
