- Abstract
- States that heterogeneous project groups today may be expected to use the mechanisms of the Web for sharing information. Metadata has been proposed as a mechanism for expressing the semantics of information and, hence, facilitate information retrieval, understanding and use. Presents an approach to sharing information which aims to use a semantic modeling language as the basis for expressing the semantics of information and designing metadata schemes. Functioning on the borderline between human and computer understandability, the modeling language would be able to express the semantics of published Web documents. Reporting on work in progress, presents the overall framework and ideas

- Abstract
- To Classify is (according to Webster's) "to distribute into classes; to arrange according to a system; to arrange in sets according to some method founded on common properties or characters." A model of classification is a type or category or (excuse the recursive definition) a class of classification "system" as mentioned in Webster's definition. One employs a classification model to implement a specific classification system. (E.g. we employ the hierarchical classification model to implement the Dewey Decimal System) An effective classification model must represent both the commonality (Webster's "common properties"), and also the differences among the items being classified. The commonality of each category or class defines a test to determine which items belong to the set that class represents. The relationships among the classes define the variability among the sets that the classification model can represent. Therefore, a classification model is more than an enumeration or other simple listing of the names of its classes. Our purpose in employing classification models is to build metadata systems that represent and manage knowledge, so that users of these systems we build can: quickly and accurately define (the commonality of) what knowledge they require, allowing the user great flexibility in how that desire is described; be presented existing information assets that best match the stated requirements; distinguish (the variability) among the candidates to determine their best choice(s), without actually having to examine the individual items themselves; retrieve the knowledge they need The MetaData model we present is Contextual Classification. It is a synthesis of several traditional metadata models, including controlled keyword indices, hierarchical classification, attribute value systems, Faceted Classification, and Evolutionary Faceted Classification. Research into building on line library systems of software and software documentation (Frakes and Pole, 19921 and Pole 19962) has shown the need and viability of combining the strengths, and minimizing the weaknesses of multiple metadata models in the development of information systems. The MetaData Object Manager (M.O.M.), a MetaData Warehouse (MDW) and editorial work flow system developed for the Thomson Financial Publishing Group, builds on this earlier research. From controlled keyword systems we borrow the idea of representing commonalties by defining formally defined subject areas or categories of information, which sets are represented by these categories names. From hierarchical classification, we borrow the concept of relating these categories and classes to each other to represent the variability in a collection of information sources. From attribute value we borrow the concept that each information source can be described in different ways, each in respect to the attribute of the information being described. From Faceted Classification we borrow the concept of relating the classes themselves into sets of classes, which a faceted classification system would describe as facets of terms. In this paper we will define the Contextual Classification model, comparing it to the traditional metadata models from which it has evolved. Using the MOM as an example, we will then discuss both the use of Contextual Classification is developing this system, and the organizational, performance and reliability

- Abstract
- Highlights 2 major problems of the WWW metadata: it will take some time before a reasonable number of people start using metadata to provide a better Web classification, and that no one can guarantee that a majority of the Web objects will be ever properly classified via metadata. Addresses the problem of how to cope with intrinsic limits of Web metadata, proposes a method to solve these problems and show evidence of its effectiveness. Examines the important problem of what is the required critical mass in the WWW for metadata in order for it to be really useful

- Abstract
- The Resource Description Framework (RDF) is an infrastructure that enables the encoding, exchange and reuse of structured metadata. RDF is an application of XML that imposes needed structural constraints to provide unambiguous methods of expressing semantics. RDF additionally provides a means for publishing both human-readable and machine-processable vocabularies designed to encourage the reuse and extension of metadata semantics among disparate information communities. The structural constraints RDF imposes to support the consistent encoding and exchange of standardized metadata provides for the interchangeability of separate packages of metadata defined by different resource description communities.

- Abstract
- To improve searching, filtering and processing of information on the Web, a common effort is made in the direction of metadata, defined as machine understandable information about Web resources or other things. In particular, the eXtensible Markup Language (XML) aims at providing a common syntax to emerging metadata formats. Proposes the Structured Graph Format (SGF) an XML compliant markup language based on structured graphs, for capturing Web sites' structure. Presents SGMapper, a client-site tool, which aims to facilitate navigation in large Web sites by generating highly interactive site maps using SGF metadata

- Abstract
- Discusses the range of applications of the XML meta language, which allows users to design their own markup language and share it with others. Instead of being confined to HTML, where 'one size fits all', industries, academic disciplines and professional organizations can use XML syntax to create a common set of tags which standardize the presentation of information. The linking abilities of XML are more powerful than HTML, so that it will support bidirectional and multiway links, as well as those to a span of text rather than to a single point

- Abstract
- Examines techniques that discover features in sets of pre-categorized documents, such that similar documents can be found on the WWW. Examines techniques which will classifiy training examples with high accuracy, then explains why this is not necessarily useful. Describes a method for extracting word clusters from the raw document features. Results show that the clustering technique is successful in discovering word groups in personal Web pages which can be used to find similar information on the WWW

- Abstract
- Describes key events in the development of cataloguing of Internet resources and ssurveys current activities. The fundamental questions are: are Internet resources worth cataloguing; is traditional MARC/AACR2 cataloguing appropriate for Internet resources; and how should resources that change location be dealt with? Libraries should start by cataloguing an Internet resource. Bibliographic records can be used to drive Web applications. Metadata holds considerable promise

- Abstract
- Metadata systems are concerned with the management of data which describes other data (datasets, catalogues, or actual database management systems) and are presently the subject of intensive research. Metadata systems can be used to store richly detailed forms of information, perform seamless wide ranging searches of information distributed across networks, and to integrate information stored in disparate repositories. Describes a model design and methods of implementation derived from the experience of the Leicester University Metadata Project. The approach utilizes the incorporation of semantic metadata in addition to resource metadata, resulting in a generally more powerful system than existing global directory services. Feature of the class of design is flexibility or implementation, with the ability to provide a coherent metadata system functioning above heterogeneous autonomous distributed databases

- Abstract
- Develops frameworks to help Internet media designers address end user information presentation preferences by advancing structures for assessing metadata design variables. Design variables are then linked to user cognitive styles. An underlying theme is that artificial intelligence methodologies may be used to help automate the Internet media design process and to provide personalized and customized experiences. User preferences concerning knowledge acquisition in online experiences provide the basis for discussions of cognitive analysis, and are extended into structural implications for media design and interaction

- Abstract
- Given the paucity of research addressing client preferences for metadata content and display in knowledge access systems, a three-year study involving a sample of Canadian public and academic libraries and their end-users, was undertaken. Gaps between user preferences and the availability and presentation of metadata elements in some current Canadian web-based knowledge access systems were identified. Ideal displays were subsequently prototyped and evaluated. Overall, end-users favoured systems containing brief, concise, and focused metadata elements, restricted to a one-screen, uncluttered display, and enhanced by a variety of hierarchical, associative, and equivalent relationship links.

- Abstract
- Current hypertext systems have been widely and effectively used on relatively small data volumes. Explores the potential of database technology for aiding the implementation of hypertext systems holding very large amounts of complex data. Databases meet many requirements of the hypermedium: persistent data management, large volumes, data modelling, multi-level architecture with abstractions and views, metadata integrated with operational data, short-term transaction processing and high-level end-user languages for searching and updating data. Describes a system implementing the storage, retrieval and recall of trails through hypertext comprising textual complex objects (to illustrate the potential for the use of data bases). Discusses weaknesses in current database systems for handling the complex modelling required

- Abstract
- Within a digital library, collections may range from an ad hoc set of objects that serve a temporary purpose to established library collections intended to persist through time. The objects in these collections vary widely, from library and data center holdings to pointers to real-world objects, such as geographic places, and the various metadata schemes that describe them. The key to integrated use of such a variety of collections in a digital library is collection metadata that represents the inherent and contextual characteristics of a collection. The Alexandria Digital Library (ADL) Project has designed and implemented collection metadata for several purposes: in XML form, the collection metadatada 'registers' the collection with the user interface client; in HTML form, it is used for user documentation; eventually, it will be used to describe the collection to network search agents; and it is used for internal collection management, including mapping the object metadata attributes to the common search parameters of the system

- Content
- The PICS, an initiative of W3C, is a technology that supports the association of descriptive labels with Web resources. By providing a single common transport syntax for metadata, PICS will support the growth of metadata systems (including library cataloguing) that are interoperable and widely supported in Web information systems. Within the PICS framework, a great diversity of resource description models can be implemented, from simple rating schemes to complex data content standards

- Abstract
- Today's enterprises employ multiple information systems which are independently developed, locally administered, and are different in logical or physical design. To share information across organisational boundaries requires a global query system capable of providing online intelligent assistance to users. Conventional technologies such as schema based query languages and hard coded schema integration are insufficient. Develops a model assisted global query system using an online repository of enterprise metadata, the metadatabase, for global query formulation and processing with adaptiveness and open systems architecture. Presents a definition model for the metadata as a knowledge system. Analyzes the improvements of the new system in relation to the old. Tests a prototype system in a computer integrated manufacturing setting
