| Abstract | Mood is an important access point in music digital libraries and online music repositories, but generating ground truth for evaluating various music mood classification algorithms is a challenging problem. This is because collecting enough human judgments is time-consuming and costly due to the subjectivity of music mood. In this study, we explore the viability of crowdsourcing music mood classification judgments using Amazon Mechanical Turk (MTurk). Specifically, we compare the mood classification judgments collected for the annual Music Information Retrieval Evaluation eXchange (MIREX) with judgments collected using MTurk. Our data show that the overall distribution of mood clusters and agreement rates from MIREX and MTurk were comparable. However, Turkers tended to agree less with the pre-labeled mood clusters than MIREX evaluators. The system evaluation results generated using both sets of data were mostly the same except for detecting one statistically significant pair using Friedman's test. We conclude that MTurk can potentially serve as a viable alternative for ground truth collection, with some reservation with regards to particular mood clusters. |

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.
