  • 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.

  • And we did it our way: A case for crowdsourcing in a digital library for musicology

    Bainbridge, David (2015)

    Conference item
    University of Waikato

    This article makes the case for a digital library based on a crowdsourcing approach for musicology. At its heart, the argument draws upon ideas present in the popular music video TV show Pop-Up Video, a format devised in the late 1990s that embellishes the shown content with info nuggets that popup as bubbles and then disappear, as the video plays. We updated and extended the concept to operate in a web environment, choosing a digital library framework as a way to organize the set of videos contained in the site, and casting the popup information collated and displayed as metadata---aspects that further progress the argument for the developed software architecture being fit-for-purpose as a tool for musicologists. The article presents a walkthrough of the developed site, and then goes on to show how the elements present---particularly the gamification elements that focus on symbolic note content entered through a range of virtual musical instruments: piano, drum-kit and guitar---can be re-purposed for use by musicology scholars.

  • 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.

  • 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.

  • A user-centered design of a personal digital library for music exploration

    Bainbridge, David; Novak, Brook Jesse; Cunningham, Sally Jo (2010)

    Conference item
    University of Waikato

    We describe the evaluation of a personal digital library environment designed to help musicians capture, enrich and store their ideas using a spatial hypermedia paradigm. The target user group is musicians who primarily use audio and text for composition and arrangement, rather than with formal music notation. Using the principle of user-centered design, the software implementation was guided by a diary study involving nine musicians which suggested five requirements for the software to support: capturing, overdubbing, developing, storing, and organizing. Moreover, the underlying spatial data-model was exploited to give raw audio compositions a hierarchical structure, and - to aid musicians in retrieving previous ideas - a search facility is available to support both query by humming and text-based queries. A user evaluation of the completed design with eleven subjects indicated that musicians, in general, would find the hypermedia environment useful for capturing and managing their moments of musical creativity and exploration. More specifically they would make use of the query by humming facility and the hierarchical track organization, but not the overdubbing facility as implemented.

  • 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.

  • 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.

  • 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).

  • 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.

  • 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.
