Searching digital music libraries

There has been a recent explosion of interest in digital music libraries. In particular, interactive melody retrieval is a striking example of a search paradigm that differs radically from the standard full-text search. Many different techniques have been proposed for melody matching, but the area lacks standard databases that allow them to be compared on common grounds––and copyright issues have stymied attempts to develop such a corpus. This paper focuses on methods for evaluating different symbolic music matching strategies, and describes a series of experiments that compare and contrast results obtained using three dominant paradigms. Combining two of these paradigms yields a hybrid approach which is shown to have the best overall combination of efficiency and effectiveness

Resource selection and data fusion for multimedia international digital libraries: an overview of the MIND project

The inspiration for MIND grew out of the problems which users face when they have remote access to thousands of heterogeneous and distributed multimedia digital libraries. A user must know where to search, how to query different media, and how to combine information from diverse resources. As digital libraries continue to proliferate, in a variety of media and from a variety of sources, the problems of resource selection, query formulation and data fusion become major obstacles to effective search and retrieval. The key goal of MIND is to develop a common system for identifying, searching and combining results from multiple digital libraries. MIND, therefore, is investigating methods for resource description and selection (i.e., gathering and updating information about digital libraries to assist in selecting those which are most likely to contain the information sought), query processing (i.e. modifying the terms contained in a query and transforming the query into the local command language), data fusion (i.e., the merging of different data retrieved from different digital libraries) and information visualisation (in particular, the automatic generation of surrogates and presentation of fused retrieved data)

A Generic Alerting Service for Digital Libraries

Users of modern digital libraries (DLs) can keep themselves up-to-date by searching and browsing their favorite collections, or more conveniently by resorting to an alerting service. The alerting service notifies its clients about new or changed documents. Proprietary and mediating alerting services fail to fluidly integrate information from differing collections. This paper analyses the conceptual requirements of this much-sought after service for digital libraries. We demonstrate that the differing concepts of digital libraries and its underlying technical design has extensive influence (a) the expectations, needs and interests of users regarding an alerting service, and (b) on the technical possibilities of the implementation of the service. Our findings will show that the range of issues surrounding alerting services for digital libraries, their design and use is greater than one may anticipate. We also show that, conversely, the requirements for an alerting service have considerable impact on the concepts of DL design. Our findings should be of interest for librarians as well as system designers. We highlight and discuss the far-reaching implications for the design of, and interaction with, libraries. This paper discusses the lessons learned from building such a distributed alerting service. We present our prototype implementation as a proof-of-concept for an alerting service for open DL software

Sometimes the Internet reads the question wrong: children’s search strategies & difficulties

When children search for information on a given topic, how do they go about searching for and retrieving information? What can their information seeking strategies tell us about the development of search interfaces for children's digital libraries, search engines and information repositories? We interviewed New Zealand (NZ) school children to seek insights into how they are conducting information searches during their education

The Físchlár digital library: networked access to a video archive of TV news

This paper presents an overview of the Físchlár digital library, a collection of over 300 hours of broadcast TV content which has been indexed to allow searching, browsing and playback of video. The system is in daily use by over 1,500 users on our University campus and is used for teaching and learning, for research, and for entertainment. It is shortly to be made available to University libraries elsewhere in Ireland. The infrastructure we use is a Gigabit ETHERNET backbone and a conventional web browser for searching and browsing video content, with a browser plug-in for streaming video. As well as providing an overview of the system, the paper concentrates on the complimentary navigation techniques of browsing and searching which are supported within Físchlár

Browsing a digital library: A new approach for the New Zealand digital library

Browsing is part of the information seeking process, used when information needs are ill-defined or unspecific. Browsing and searching are often interleaved during information seeking to accommodate changing awareness of information needs. Digital Libraries often support full-text search, but are not so helpful in supporting browsing. Described here is a novel browsing system created for the Greenstone software used by the New Zealand Digital Library that supports users in a more natural approach to the information seeking process. © Springer-Verlag Berlin Heidelberg 2003

Moving towards Adaptive Search

Information retrieval has become very popular over the last decade with the advent of the Web. Nevertheless, searching on the Web is very different to searching on smaller, often more structured collections such as intranets and digital libraries. Such collections are the focus of the recently started AutoAdapt project1. The project seeks to aid user search by providing well-structured domain knowledge to assist query modification and navigation. There are two challenges: acquiring the domain knowledge and adapting it automatically to the specific interest of the user community. At the workshop we will demonstrate an implemented prototype that serves as a starting point on the way to truly adaptive search

Accessing Digital Libraries: A Study of ARL Members\u27 Digital Projects

To ensure efficient access to and integrated searching capabilities for their institution\u27s new digital library projects, the authors studied Web sites of the Association of Research Libraries\u27 (ARL) 111 academic, English-language libraries. Data were gathered on 1117 digital projects, noting library Web site and project access, metadata, and project types

The TREC2001 video track: information retrieval on digital video information

The development of techniques to support content-based access to archives of digital video information has recently started to receive much attention from the research community. During 2001, the annual TREC activity, which has been benchmarking the performance of information retrieval techniques on a range of media for 10 years, included a ”track“ or activity which allowed investigation into approaches to support searching through a video library. This paper is not intended to provide a comprehensive picture of the different approaches taken by the TREC2001 video track participants but instead we give an overview of the TREC video search task and a thumbnail sketch of the approaches taken by different groups. The reason for writing this paper is to highlight the message from the TREC video track that there are now a variety of approaches available for searching and browsing through digital video archives, that these approaches do work, are scalable to larger archives and can yield useful retrieval performance for users. This has important implications in making digital libraries of video information attainable

Research and resources in North American studies : plus ca change, plus c'est la même chose ; sixth scientific symposium Frankfurt – 6. Wissenschaftliches Symposium Frankfurt, Saturday, 7 October 2006, panel 4, 9:45 – 11:00 a.m.

Large American research libraries have been acquiring - by purchase and by lease - huge multi-disciplinary electronic collections of primary and secondary source materials. For example, the Digital Evans and Canadian Poetry easily make available to scholars primary materials that once were scattered in libraries across North America and Europe. The American State Papers, 1789 – 1838 collection allows easier searching of fragile rare materials. Collections made by libraries digitizing their own holdings, such the Archive of Early American Images from the John Carter Brown Library at Brown University, make research materials more discoverable and usable. Yet recent scholarship in American Studies by American and European scholars makes relatively little use of these new materials. Both disparities and congruities in what scholars use and what research libraries collect are apparent. Some simple reasons explain the dissonance. Furthermore, conversations with scholars suggest that materials and collections alone will not suffice to support research. Librarians’ skills and actions will increase the value of the new research materials
