  • Social music in cars

    Cunningham, Sally Jo; Nichols, David M.; Bainbridge, David; Ali, Hasan (2014)

    Conference item
    University of Waikato

    This paper builds an understanding of how music is currently experienced by a social group travelling together in a car - how songs are chosen for playing, how music both reflects and influences the group’s mood and social interaction, who supplies the music, the hardware/software that supports song selection and presentation. This fine-grained context emerges from a qualitative analysis of a rich set of ethnographic data (participant observations and interviews) focusing primarily on the experience of in-car music on moderate length and long trips. We suggest features and functionality for music software to enhance the social experience when travelling in cars, and prototype and test a user interface based on design suggestions drawn from the data.

  • 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.

  • Visual collaging of music in a digital library

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

    Conference item
    University of Waikato

    This article explores the role visual browsing can play within a digital music library. The context to the work is provided through a review of related techniques drawn from the fields of digital libraries and human computer interaction. Implemented within the open source digital library toolkit Greenstone, a prototype system is described that combines images located through textual metadata with a visualisation technique known as collaging to provide a leisurely, undirected interaction with a music collection. Emphasis in the article is given to the augmentations of the basic technique to work in the musical domain.

  • 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.

  • 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.

  • 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.

  • Parallel processing videos in very large digital libraries

    Thompson, John; Bainbridge, David; Roüast, Maxime (2012)

    Conference item
    University of Waikato

    Nowhere are the 'growing pains' of Very Large-scale Digital Libraries more pronounced than in collections containing multimedia data. Not only do such collections contain large numbers of items, but they also push the boundaries of scale in terms of storage space and processing expense. In this paper we explore how applying parallel processing open-source libraries and techniques-previously developed for and applied to textual content-can be of benefit to multimedia digital libraries. We provide a real-world use case of ingesting video into the ReplayMe! system, an extension of the Greenstone digital library software, that simultaneously records and ingests all of the free-to-air television channels available in New Zealand. Current ingest of video in ReplayMe! is intentionally light due to processing time constraints on the single processor architecture it was developed on. The work reported here investigates how this system can be scaled up to include the conversion of the broadcast video transport format to a suitable a streaming format (MP4) and to automatically extract content analysis based keyframes, while still performing within real-time. By applying parallel processing, and utilizing a cluster of sixteen desktop computers, the paper shows how this processing time can be significantly reduced compared to the equivalent computation if conducted serially. We then generalize the work, and show how the same basic techniques can be applied to other common digital library software such as DSpace to provide similar advantages when dealing with processor intensive content.

  • 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).

  • Live television in a digital library

    Roüast, Maxime; Bainbridge, David (2012)

    Conference item
    University of Waikato

    The number of channels of digital television is increasing, particularly the number that are free-to-air. However due to the nature of broadcasting, this morass of information is not, for the main part, organized - -it is principally a succession of images and sound transmitted as multiplexed streams of data. Compare this deluge that terrestrially bombards our homes with the information available in the digital libraries we access over the Internet - -stored using software purpose built to help organize carefully curated sets of documents. This project brings together these two seemingly incompatible concepts to develop a software environment that concurrently captures all the available live television channels - -so a user does not need to proactively choose what to record - -and segments them into files which are then imported into a digital video library with a user interface designed to work from a multimedia remote control. A shifting time-based "window" of all recordings is maintained - -we settled on from the last two weeks so as to be practicably operable on a regular desktop PC. The system leverages off the information contained in the electronic program guide and the video recordings to generate metadata suitable for the digital library. A user evaluation of the developed prototype showed a high level of participant satisfaction across a range of attributes, notably date-based searching.

  • Greenbug: a hybrid web-inspector, debugger and design editor for greenstone

    Bainbridge, David; McIntosh, Sam J.; Nichols, David M. (2013)

    Conference item
    University of Waikato

    In this paper we present Greenbug: a hybrid web inspector, debugger and design editor developed for use with the open source digital library software Greenstone 3. Inspired by the web development tool Firebug, Greenbug is more tightly coupled with the underlying (digital library) server than that provided by Firebug; for example, Greenbug has a fine-grained knowledge of the connection between the underlying file system and the rendered web content, and also provides the ability to commit any changes made through the web interface back to the underlying file system. Moreover, because web page production in Greenstone 3 is the result of an XSLT processing pipeline, the necessarily well-formed hierarchical XML content can be manipulated into a graphical representation, which can then be manipulated directly through a visual interface supplied by Greenbug. We showcase the interface in use, provide a brief overview of implementation details, and conclude with a discussion on how the approach can be adapted to other XSLT transformation-based content management systems, such as DSpace.

  • Low-cost semantic enhancement to digital library metadata and indexing: simple yet effective strategies

    Hinze, Annika; Bainbridge, David; Cunningham, Sally Jo; Downie, J. Stephen (2016)

    Conference item
    University of Waikato

    Most existing digital libraries use traditional lexically-based retrieval techniques. For established systems, completely replacing, or even making significant changes to the document retrieval mechanism (document analysis, indexing strategy, query processing and query interface) would require major technological effort, and would most likely be disruptive. In this paper, we describe ways to use the results of semantic analysis and disambiguation, while retaining an existing keyword-based search and lexicographic index. We engineer this so the output of semantic analysis (performed off-line) is suitable for import directly into existing digital library metadata and index structures, and thus incorporated without the need for architecture modifications.

  • The impact of MIREX on scholarly research (2005-2010)

    Cunningham, Sally Jo; Bainbridge, David; Downie, J. Stephen (2012)

    Conference item
    University of Waikato

    This paper explores the impact of the MIREX (Music Information Retrieval Evaluation eXchange) evaluation initiative on scholarly research. Impact is assessed through a bibliometric evaluation of both the MIREX extended abstracts and the papers citing the MIREX results, the trial framework and methodology, or MIREX datasets. Impact is examined through number of publications and citation analysis. We further explore the primary publication venues for MIREX results, the geographic distribution of both MIREX contributors and researchers citing MIREX results, and the spread of MIREX-based research beyond the MIREX contributor teams. This analysis indicates that research in this area is highly collaborative, has achieved an international dissemination, and has grown to have a significant profile in the research literature.

  • Page turning and image size in a digital music stand

    Bell, Timothy C.; Church, Annabel; McPherson, John; Bainbridge, David (2005)

    Conference item
    University of Waikato

    This paper investigates attributes of the electronic display of sheet music necessary for the development of a digital music stand. We explore the two conflicting goals of minimising page turning effort and maximising the readability of images by conducting two user experiments. In our first experiment participants trialed various page turning methods through a sight-reading exercise, and filled out a questionnaire upon completion. In the second experiment participants viewed music at different sizes while listening to an audio rendition of the piece, and were asked to note any mistakes that occured in the played audio. Results from our experimentations showed that scrolling techniques did not work as well as page replacement methods, and that some reduction in the size of the music displayed is possible without significantly degrading reader accuracy.

  • Tag insertion complexity

    Yeates, Stuart Andrew; Witten, Ian H.; Bainbridge, David (2001)

    Conference item
    University of Waikato

    This paper is about inferring markup information, a generalization of part-of-speech-tagging. We use compression models based on a marked-up training corpus and apply them to fresh, unmarked, text. In effect, this technique builds filters that extract information from text in a way that is generalized because it depends on training text rather than preprogrammed heuristics.
