  • Identifying music documents in a collection of images

    Bainbridge, David; Bell, Timothy C. (2006)

    Conference item
    University of Waikato

    Digital libraries and search engines are now well-equipped to find images of documents based on queries. Many images of music scores are now available, often mixed up with textual documents and images. For example, using the Google “images” search feature, a search for “Beethoven” will return a number of scores and manuscripts as well as pictures of the composer. In this paper we report on an investigation into methods to mechanically determine if a particular document is indeed a score, so that the user can specify that only musical scores should be returned. The goal is to find a minimal set of features that can be used as a quick test that will be applied to large numbers of documents. A variety of filters were considered, and two promising ones (run-length ratios and Hough transform) were evaluated. We found that a method based around run-lengths in vertical scans (RL) that out-performs a comparable algorithm using the Hough transform (HT). On a test set of 1030 images, RL achieved recall and precision of 97.8% and 88.4% respectively while HT achieved 97.8% and 73.5%. In terms of processor time, RL was more than five times as fast as HT.

  • Experiences with the Greenstone digital library software for international development

    Nichols, David M.; Rose, John; Bainbridge, David; Witten, Ian H. (2010)

    Conference item
    University of Waikato

    Greenstone is a versatile open source multilingual digital library environment, emerging from research on text compression within the New Zealand Digital Library Research Project in the Department of Computer Science at the University of Waikato. In 1997 we began to work with Human Info NGO to help them produce fully-searchable CD-ROM collections of humanitarian information. The software has since evolved to support a variety of application contexts. Rather than being simply a delivery mechanism, we have emphasised the empowerment of users to create and distribute their own digital collections.

  • Perambulating libraries: Demonstrating how a Victorian idea can help OLPC users share books

    Witten, Ian H.; Bainbridge, David (2011)

    Conference item
    University of Waikato

    In this extended abstract we detail how the open source digital library toolkit Greenstone [5] can help users of the XOlaptop— produced by the One Laptop Per Child Foundation— manage and share electronic documents. The idea draws upon mobile libraries (bookmobiles) for its inspiration, which first appeared in Victorian times. The implemented technique works by building on the Mesh network that is instrumental to the XO-laptop approach. To use the technique, on each portable XO-laptop a version of Greenstone is installed, allowing the owner to develop and manage their own set of books. The version of Greenstone has been adapted to support a form of interoperability we have called Digital Library Talkback. On the Mesh, when two XO-laptops “see” each other, the two users can search and browse the other user’s digital library; when they see a book they like, they can have it transferred to their library with a single click using the Digital Library Talkback mechanism.

  • Finding new music: a diary study of everyday encounter with novel songs

    Cunningham, Sally Jo; Bainbridge, David; McKay, Dana (2007)

    Conference item
    University of Waikato

    This paper explores how we, as individuals, purposefully or serendipitously encounter 'new music' (that is, music that we haven’t heard before) and relates these behaviours to music information retrieval activities such as music searching and music discovery via use of recommender systems. 41 participants participated in a three-day diary study, in which they recorded all incidents that brought them into contact with new music. The diaries were analyzed using a Grounded Theory approach. The results of this analysis are discussed with respect to location, time, and whether the music encounter was actively sought or occurred passively. Based on these results, we outline design implications for music information retrieval software, and suggest an extension of 'laid back' searching.

  • Greenstone as a music digital library toolkit

    Bainbridge, David; Cunningham, Sally Jo; Downie, J. Stephen (2004-10-01)

    Conference item
    University of Waikato

    Greenstone is an open source digital library system that has developed and matured since its inception in 1995. Today it is used in over 60 countries, with a strong emphasis on humanitarian aid. The software is also used as a framework for research in other fields such has human computer interaction, text-mining, and ethnography. This article provides a summary of Greenstone's uses to date with music documents. First we discuss incorporating musical formats into the Greenstone system; then we describe provision for searching and browsing in a music collection.

  • Structured audio content analysis and metadata in a digital library

    Bainbridge, David; Downie, J. Stephen; Ehmann, Andreas F. (2012)

    Conference item
    University of Waikato

    This work illustrates how audio content analysis of music and manually assigned structural temporal metadata can be used to form a digital library designed for musicological exploration. In addition to text-based searching and browsing, the document view is enriched with an interactive structured audio time-line that shows ground-truth data representing the logical segments to the song, and a version that was automatically generated for comparison. A self-similarity "heat" map is also displayed, and is interactive. Clicking within the map at a co-ordinate (x,y) results in the audio being played simultaneous at time offset x and y, panned left and right, respectively, to make it easier for the listener to separate out the differences. The musicologist can also initiate an audio content based query starting at any point in the song. This produces a ranked result set which can be further studied through their respective document views. Alternatively they can perform a musical structure search (for example, for songs that contain the structure b, b, c, b, c).

  • A workflow for document level interoperability

    Bainbridge, David; Cunningham, Sally Jo (2011)

    Conference item
    University of Waikato

    This article describes a software environment called the Exchange Center that helps digital librarians manage the workflow of sourcing documents and metadata from various repositories. The software is built on Greenstone but does not require its use as the final digital library server. After describing the software architecture we provide two scenarios of its use: a private library of recipes, which ultimately involves collaboration with other cooks; and a digital library that aggregates the collections of various host institutions that use different repository software.

  • Seamless web editing for curated content

    Bainbridge, David; Novak, Brook Jesse (2010)

    Conference item
    University of Waikato

    In this paper we present a new framework for editing that we have called Seaweed (short for seamless web editing) which enables authors to directly edit content on web pages within any common web browser—much like a word-processor—without the need of switching between modes. There are numerous ways to utilise the technique. This article reports on work integrating it with blogging software to support the direct creation and editing of curated content, and its subsequent evaluation through two field trials.

  • Greenstone: A platform for distributed digital library applications

    Bainbridge, David; Buchanan, George; McPherson, John R.; Jones, Steve; Mahoui, Abdelaziz; Witten, Ian H. (2001)

    Conference item
    University of Waikato

    This paper examines the issues surrounding distributed Digital Library protocols. First, it reviews three prominent digital library protocols: Z39.50, SDLIP, and Dienst, plus Greenstone’s own protocol. Then, we summarise the implementation in the Greenstone Digital Library of a number of different protocols for distributed digital libraries, and describe sample applications of the same: a digital library for children, a translator for Stanford’s Simple Digital Library Interoperability Protocol, a Z39.50 client, and a bibliographic search tool. The paper concludes with a comparison of all four protocols, and a brief discussion of the impact of distributed protocols on the Greenstone system.

  • Practical digital library interoperability standards

    Bainbridge, David; Witten, Ian H. (2005)

    Conference item
    University of Waikato

    As the field of digital libraries matures and new systems and standards develop, the ability to interoperate between systems becomes paramount. This tutorial gives a practical introduction to many recent standards and de facto standards for interoperability, and illustrates them using open source digital library software-including online demonstrations of interoperation issues and solutions. Core standards that are discussed include Dublin Core, OAI-PMH, METS, and MODS. We use interoperation between Greenstone and DSpace as a motivating case study. For those demonstrations that involve Greenstone, attendees who wish to may bring their laptops, install Greenstone from a CD-ROM that we will provide, along with various sample files, and follow along with the demonstrations on their own machine.

  • That's 'é' not 'þ' '?' or '☐': a user-driven context-aware approach to erroneous metadata in digital libraries

    Bainbridge, David; Twidale, Michael B.; Nichols, David M. (2011)

    Conference item
    University of Waikato

    In this paper we present a novel system for user-driven integration of name variants when interacting with web-based information systems. The growth and diversity of online information means that many users experience disambiguation and collocation errors in their information searching. We approach these issues via a client-side JavaScript browser extension that can reorganise web content and also integrate remote data sources. The system is illustrated through three worked examples using existing digital libraries.
