| Abstract | Recently, music retrieval is getting more and more attentions, especially for the query by humming (QBH), which is straightforward and convenient for usage. However, the difference between humming phrase matching and the precision of singer humming increase the difficulty of retrieval. Apart from retrieval precision, retrieval time is another issue should be taken into consideration. In this paper, we use two-stage searching approach for music retrieval. Since PAT tree (variant of Patricia tree, practical algorithm to retrieve information coded in alphanumeric) shows an excellent performance in matching partial sequence, in the first stage, the simply reduced note interval is adopted as a key phrase of PAT tree for fast indexing the candidate regions from the feature sequences in the database. In addition, the searching of partial sequences suffering from the insertion, deletion and transposition errors works well in the indexing of reduced note interval. The resulting diversity of candidates may be further reduced via a more complicated dynamic time warping (DTW) comparison in the second step. Our approach not only avoids the exhausted computation in the simple DTW approach, but preservers the fault-tolerance capability in the matching process. |

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.
