Analysis of this structure will be useful for music segmentation, indexing and thumbnailing. We present an algorithm that can automatically analyze the repetitive structure of musical signals. First, the algorithm detects the repetitions of each segment affixed length in a piece using dynamic programming. Second, the algorithm summarizes this repetition information and infers the structure based on heuristic rules. The performance of the approach is demonstrated visually using figures for qualitative evaluation, and by two structural similarity measures for quantitative evaluation. Based on the structural analysis result, a method for music thumbnailing is proposed. The preliminary results obtained using a corpus of Beatles' songs show that automatic structural analysis and thumbnailing of music are possible.","PeriodicalId":248854,"journal":{"name":"2003 Joint Conference on Digital Libraries, 2003.

The model embraced by the OAI-PMH is that of metadata harvesting, where value-added services (by a \"service provider\") are constructed on cached copies of the metadata extracted from the repositories of the harvester's choosing. While this model dispenses with the well-known problems of distributed searching, it introduces the problem of synchronization. Stated simply, this problem arises when the service provider's copy of the metadata does not match the metadata currently at the constituent repositories. We define some metrics for describing the synchronization problem in the OAI-PMH. Based on these metrics, we study the synchronization problem of the OAI-PMH framework and propose several approaches for harvesters to implement better synchronization. In particular, if a repository knows its update frequency, it can publish it in an OAI-PMH identify response using an optional about container that borrows from RDF Site Syndication (RSS) Format.","PeriodicalId":248854,"journal":{"name":"2003 Joint Conference on Digital Libraries, 2003.

After being open for a year and expanding the size of the collection by another million documents, the LTDL team is faced with several challenges. We built the LTDL using the University of Michigan's DLXS middleware and the XPAT search engine.

We analyze the emergence of hyperlinked structures within the ibiblio collection. In the context of ibiblio, we analyze the suitability of Barabasi's model of preferential attachment to describe the distribution of incoming links. We find that the degree of maintainer activity for a given site (as measured by the voluntary development of descriptive metadata) is a stronger link count predictor for ibiblio than is a site's age, as the standard model predicts. Thus we argue that the efforts of ibiblio's contributors positively affect the popularity of their materials.","PeriodicalId":248854,"journal":{"name":"2003 Joint Conference on Digital Libraries, 2003.

As well as functioning as a live service, DSpace is intended as a base for extending repository functionality, particularly to address long-term preservation concerns.
