- Abstract
- In this paper, we present a formulation and case studies of the conditions for patenting content-based retrieval processes in digital libraries, especially in image libraries. Inventors and practitioners demand a formulation of the conditions for patenting data-processing processes as computer-related inventions in the form of computer programs. A process for content-based retrieval often consists of a combination of prior disclosed means and also comprises means for parameter setting that is adjusted to retrieve specific kinds of images in certain narrow domains. We focus on requirements for technical advancement (nonobviousness) in the combination of data-processing means, i.e., processes and specification (enablement) on the means for parameter setting in computer programs. Our formulation follows the standards of patent examination and litigation on computer-related inventions in the US. We confirm the feasibility and accountability of our formulation by applying it to several inventions patented in the US.

- Abstract
- Music websites are ubiquitous, and music downloads, such as MP3, are a major source of Web traffic. As the amount of musical content increases and the Web becomes an important mechanism for distributing music, we expect to see a rising demand for music search services. Many currently available music search engines rely on file names, song title, composer or performer as the indexing and retrieval mechanism. These systems do not make use of the musical content. We believe that a more natural, effective, and usable music-information retrieval (MIR) system should have audio input, where the user can query with musical content. We are developing a system called MusArt for audio-input MIR. With MusArt, as with other audio-input MIR systems, a user sings or plays a theme, hook, or riff from the desired piece of music. The system transcribes the query and searches for related themes in a database, returning the most similar themes, given some measure of similarity. We call this "retrieval by query." In this paper, we describe the architecture of MusArt. An important element of MusArt is metadata creation: we believe that it is essential to automatically abstract important musical elements, particularly themes. Theme extraction is performed by a subsystem called MME, which we describe later in this paper. Another important element of MusArt is its support for a variety of search engines, as we believe that MIR is too complex for a single approach to work for all queries. Currently, MusArt supports a dynamic time-warping search engine that has high recall, and a complementary stochastic search engine that searches over themes, emphasizing speed and relevancy. The stochastic search engine is discussed in this paper.

- Abstract
- From a quantitative and qualitative point of view the ETH Library is offering its users an extensive choice of information services. In this respect all researchers, all scientists and also all students have access to nearly all relevant information. This is one side of the coin. On the other hand, this broad, but also heterogeneous bundle of information sources has disadvantages, which should not be underestimated: The more information services and information channels you have, the more complex is it to find what you want to get for your scientific work. A portal-like integration of all the different information resources is still missing. The vision, the main goal of the project "Knowledge Portal" is, to develop a central access system in terms of a "single-point-of-access" for all electronic information services. This means, that all these sources - from the library's catalogue and the fulltext inhouse applications to external, licensed sources - should be accessible via one central Web service. Although the primary target group for this vision is the science community of the ETH Zurich, the interested public should also be taken into account, for the library has also a nation-wide responsibility.The general idea to launch a complex project like that comes from a survey the library did one and a half years ago. We asked a defined sample of scientists what they expected to get from their library and one constant answer was, that they wanted to have one point of access to all the electronic library services and besides this, the search processes should be as simple as possible. We accepted this demand as an order to develop a "single-point-of-access" to all electronic services the library provides. The presentation gives an overview about the general idea of the project and describes the current status.

- Abstract
- The Europeana, the European digital library web-service, is being developed in the framework of the EU-funded network EDLnet. The demo version of this webservice was shown at an international conference at the German National Library in Frankfurt on 1 February 2008, the prototype will be launched in November 2008. In November 2007 the EDL Foundation was established to provide cross-domain multilingual access to Europe's cultural heritage. It will facilitate formal agreement across museums, archives, audio-visual archives and libraries on how to cooperate in the delivery and sustainability of a joint portal and will provide a legal framework for use by the EU for funding purposes and as a springboard for future governance. The European Commission is supporting the process towards the Europeana with a set of projects centering on The European Library. This webservice created by the European national libraries is seen as one of the major building blocks of the Europeana.

- Abstract
- While the Web has grown significantly in recent years, some portions of the Web remain largely underdeveloped, as shown in a lack of high-quality content and functionality. An example is the Arabic Web, in which a lack of well-structured Web directories limits users' ability to browse for Arabic resources. In this research, we proposed an approach to building Web directories for the underdeveloped Web and developed a proof-of-concept prototype called the Arabic Medical Web Directory (AMedDir) that supports browsing of over 5,000 Arabic medical Web sites and pages organized in a hierarchical structure. We conducted an experiment involving Arab participants and found that the AMedDir significantly outperformed two benchmark Arabic Web directories in terms of browsing effectiveness, efficiency, information quality, and user satisfaction. Participants expressed strong preference for the AMedDir and provided many positive comments. This research thus contributes to developing a useful Web directory for organizing the information in the Arabic medical domain and to a better understanding of how to support browsing on the underdeveloped Web.

- Abstract
- Information subject gateways provide targeted discovery services for their users, giving access to Web resources selected according to quality and subject coverage criteria. Information gateways recognise that they must collaborate on a wide range of issues relating to content to ensure continued success. This report is informed by discussion of content activities at the 1999 Imesh Workshop. The author considers the implications for subject based gateways of co-operation regarding coverage policy, creation of metadata, and provision of searching and browsing across services. Other possibilities for co-operation include working more closely with information providers, and diclosure of information in joint metadata registries

- Abstract
- 'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

- Abstract
- Libraries have had web presences since the introduction of the World Wide Web. Providing access to information provided by the library has been attempted through various means throughout the years but no method has been as popular or pervasive as the uses of library gateways and portals. Development of gateways and portals in libraries has been affected by many factors many of which have been outside the direct control of libraries or librarians. Both the history of library practice in this area and these external factors have had a substantial impact on the state of library portal and gateway development today.

- Abstract
- The German information science community - with the support of the two main funding agencies in Germany - will develop a scientific portal, vascoda, for cross-searching distributed metadata collections. In platitudinous words, one of the services of vascoda is going to be a ldquoGooglerdquo-like search for the academic community, an easy to use, yet sophisticated search-engine to supply information on high-quality resources from different media and technical environments. Reaching this objective requires considerable standardisation activity amongst the main players to harmonise the already existing services (e.g. regarding metadata, protocols, etc.). The co-operation amongst the participants including both of the funding agencies is creating a unique team-work situation in Germany thus strengthening the information science community.

- Abstract
- The BAER Web Resources Group was charged in October 1999 with defining and describing the parameters of electronic resources that do not clearly belong to the categories being defined by the BAER Digital Group or the BAER Electronic Journals Group. After some difficulty identifying precisely which resources fell under the Group's charge, we finally named the following types of resources for our consideration: web sites, electronic texts, indexes, databases and abstracts, online reference resources, and networked and non-networked CD-ROMs. Electronic resources are a vast and growing collection that touch nearly every department within the Library. It is unrealistic to think one department can effectively administer all aspects of the collection. The Group then began to focus on the concern of bibliographic access to these varied resources, and to define parameters for handling or processing them within the Library. Some key elements became evident as the work progressed. * Selection process of resources to be acquired for the collection * Duplication of effort * Use of CORC * Resource Finder design * Maintenance of Resource Finder * CD-ROMs not networked * Communications * Voyager search limitations. An unexpected collaboration with the Web Development Committee on the Resource Finder helped to steer the Group to more detailed descriptions of bibliographic access. This collaboration included development of data elements for the Resource Finder database, and some discussions on Library staff processing of the resources. The Web Resources Group invited expert testimony to help the Group broaden its view to envision public use of the resources and discuss concerns related to technical services processing. The first testimony came from members of the Resource Finder Committee. Some background information on the Web Development Resource Finder Committee was shared. The second testimony was from librarians who select electronic texts. Three main themes were addressed: accessing CD-ROMs; the issue of including non-networked CD-ROMs in the Resource Finder; and, some special concerns about electronic texts. The third testimony came from librarians who select indexes and abstracts and also provide Reference services. Appendices to this report include minutes of the meetings with the experts (Appendix A), a list of proposed data elements to be used in the Resource Finder (Appendix B), and recommendations made to the Resource Finder Committee (Appendix C). Below are summaries of the key elements.

- Abstract
- This article presents an exploratory study of Blobgects, an experimental interface for an online museum catalog that enables social tagging and blogging activity around a set of cultural heritage objects held by a preeminent museum of anthropology and archaeology. This study attempts to understand not just whether social tagging and commenting about these objects is useful but rather whose tags and voices matter in presenting different expert perspectives around digital museum objects. Based on an empirical comparison between two different user groups (Canadian Inuit high-school students and museum studies students in the United States), we found that merely adding the ability to tag and comment to the museum's catalog does not sufficiently allow users to learn about or engage with the objects represented by catalog entries. Rather, the specialist language of the catalog provides too little contextualization for users to enter into the sort of dialog that proponents of Web 2.0 technologies promise. Overall, we propose a more nuanced application of Web 2.0 technologies within museums - one which provides a contextual basis that gives users a starting point for engagement and permits users to make sense of objects in relation to their own needs, uses, and understandings.

- Abstract
- This chapter describes not so much what digital libraries are but what digital libraries with semantic support could and should be. It discusses the nature of Knowledge Organization Systems (KOS) and how KOS can support digital library users. It projects a vision for designers to make and for users to demand better digital libraries. What is a digital library? The term \Digital Library" (DL) is used to refer to a range of systems, from digital object and metadata repositories, reference-linking systems, archives, and content management systems to complex systems that integrate advanced digital library services and support for research and practice communities. A DL may offer many technology-enabled functions and services that support users, both as information producers and as information users. Many of these functions appear in information systems that would not normally be considered digital libraries, making boundaries even more blurry. Instead of pursuing the hopeless quest of coming up with the definition of digital library, we present a framework that allows a clear and somewhat standardized description of any information system so that users can select the system(s) that best meet their requirements. Section 2 gives a broad outline for more detail see the DELOS DL Reference Model.

- Abstract
- Do a search on AltaVista for "algebra". What do you get? Nearly 700,000 hits, of which AltaVista will allow you to view only what it determines is the top 200. Major search engines such as AltaVista, Excite, HotBot, Lycos, and the like continue to provide a valuable service, but with the recent growth of the Internet, topic-specific sites that provide some organization to the topic are increasingly important. It the goal of the Mathematics Archives to make it easier for the ordinary user to find useful mathematical information on the Web. The Mathematics Archives (http://archives.math.utk.edu) is a multipurpose site for mathematics on the Internet. The focus is on materials which can be used in mathematics education (primarily at the undergraduate level). Resources available range from shareware and public domain software to electronic proceedings of various conferences, to an extensive collection of annotated links to other mathematical sites. All materials on the Archives are categorized and cross referenced for the convenience of the user. Several search mechanisms are provided. The Harvest search engine is implemented to provide a full text search of most of the pages on the Archives. The software we house and our list of annotated links to mathematical sites are both categorized by subject matter. Each of these collections has a specialized search engine to assist the user in locating desired material. Services at the Mathematics Archives are divided up into five broad topics: * Links organized by Mathematical Topics * Software * Teaching Materials * Other Math Archives Features * Other Links
