- Abstract
- This paper describes the information properties of museum specimen labels and machine learning tools to automatically extract Darwin Core (DwC) and other metadata from these labels processed through Optical Character Recognition (OCR). The DwC is a metadata profile describing the core set of access points for search and retrieval of natural history collections and observation databases. Using the HERBIS Learning System (HLS) we extract 74 independent elements from these labels. The automated text extraction tools are provided as a web service so that users can reference digital images of specimens and receive back an extended Darwin Core XML representation of the content of the label. This automated extraction task is made more difficult by the high variability of museum label formats, OCR errors and the open class nature of some elements. In this paper we introduce our overall system architecture, and variability robust solutions including, the application of Hidden Markov and Naïve Bayes machine learning models, data cleaning, use of field element identifiers, and specialist learning models. The techniques developed here could be adapted to any metadata extraction situation with noisy text and weakly ordered elements.

- Abstract
- The digitized version of the only extant copy of Archimedes' key mathematical and scientific works contains over 6,500 images and 130 pages of transcriptions. Metadata is essential for managing, integrating and accessing these digital resources in the Web 2.0 environment. The Dublin Core Metadata Element Set meets many of our needs. It offers the needed flexibility and applicability to a variety of data sets containing different texts and images in a dynamic technical environment. The program team has continued to refine its data dictionary and elements based on the Dublin Core standard and feedback from the Dublin Core community since the 2006 Dublin Core Conference. This presentation cites the application and utility of the DCMI Standards during the final phase of this decade-long program. Since the 2006 conference, the amount of data has grown tenfold with new imaging techniques. Use of the DCMI Standards for integration across digital images and transcriptions will allow the hosting and integration of this data set and other cultural works across service providers, libraries and cultural institutions.

- Abstract
- Dublin Core is often presented as a modern form of catalog card -- a set of elements (and now qualifiers) that describe resources in a complete package. Sometimes it is proposed as an exchange format for sharing records among multiple collections. The founding principle that "every element is optional and repeatable" reinforces the notion that a Dublin Core description is to be taken as a whole. This paper, in contrast, is based on a much different premise: Dublin Core is a language. More precisely, it is a small language for making a particular class of statements about resources. Like natural languages, it has a vocabulary of word-like terms, the two classes of which -- elements and qualifiers -- function within statements like nouns and adjectives; and it has a syntax for arranging elements and qualifiers into statements according to a simple pattern. Whenever tourists order a meal or ask directions in an unfamiliar language, considerate native speakers will spontaneously limit themselves to basic words and simple sentence patterns along the lines of "I am so-and-so" or "This is such-and-such". Linguists call this pidginization. In such situations, a small phrase book or translated menu can be most helpful. By analogy, today's Web has been called an Internet Commons where users and information providers from a wide range of scientific, commercial, and social domains present their information in a variety of incompatible data models and description languages. In this context, Dublin Core presents itself as a metadata pidgin for digital tourists who must find their way in this linguistically diverse landscape. Its vocabulary is small enough to learn quickly, and its basic pattern is easily grasped. It is well-suited to serve as an auxiliary language for digital libraries. This grammar starts by defining terms. It then follows a 200-year-old tradition of English grammar teaching by focusing on the structure of single statements. It concludes by looking at the growing dictionary of Dublin Core vocabulary terms -- its registry, and at how statements can be used to build the metadata equivalent of paragraphs and compositions -- the application profile.

- Abstract
- Das »Semantic Web« bildet einen der wichtigsten, aktuellen Trends in der Weiterentwicklung des World Wide Web. Ehrgeizige Vision dieser nächsten Generation des WWW ist es, durch semantische Anreicherung von Information eine neue Qualität in der Bereitstellung von Inhalten und Diensten zu erreichen und vollständig neue Anwendungsmöglichkeiten für das Web zu eröffnen. Wichtige Ziele der Entwicklung des Semantic Web sind dabei die verbesserte Unterstützung von Kooperation zwischen Menschen und Computern und die intelligente Assistenz bei der Durchführung von Aufgaben in kooperativen verteilten Informationsumgebungen. Schlüssel zur Erreichung dieser Ziele sind die Anreicherung von Daten im Web mit Metadaten, welche diese Daten in einen semantischen Kontext einbetten. Diese Kontextinformation wird durch Software-Anwendungen interpretiert und zur Informationsfilterung, Verfeinerung von Anfragen und zur Bereitstellung intelligenter Assistenten verwendet. Eine große Herausforderung stellt dabei die geeignete Modellierung und Beschreibung des Kontexts dar. Diese muss eine automatische, globale Interpretation ermöglichen, ohne dass auf ein allgemeingültiges semantisches Beschreibungsschema zurückgegriffen werden kann. Die Vereinbarung eines solchen allgemeingültigen Schemas ist in einem derart umfangreichen, heterogenen und autonomen Rahmen, wie ihn das WWW darstellt, nicht möglich.

- Abstract
- In diesem Kapitel wird die zentrale Bedeutung der Annotation von Webdokumenten bzw. von Ressourcen in einem Semantischen Web diskutiert. Es wird auf aktuelle Methoden und Techniken in diesem Gebiet eingegangen, insbesondere wird das Phänomen "Social Tagging" als zentrales Element eines "Social Semantic Webs" beleuchtet. Weiters wird der Frage nachgegangen, welchen Mehrwert "Tag Recommender" beim Annotationsvorgang bieten, sowohl aus Sicht des End-Users aber auch im Sinne eines kollaborativen Ontologieerstellungsprozesses. Schließlich wird ein Funktionsprinzip für einen semi-automatischen Tag-Recommender vorgestellt unter besonderer Berücksichtigung der Anwendbarkeit in einem Corporate Semantic Web.

- Abstract
- This paper deals with the problem of modeling Web information resources using expert knowledge and personalized user information for improved Web searching capabilities. We propose a "Web information space" model, which is composed of Web-based information resources (HTML/XML [Hypertext Markup Language/Extensible Markup Language] documents an the Web), expert advice repositories (domain-expert-specified metadata for information resources), and personalized information about users (captured as user profiles that indicate users' preferences about experts as well as users' knowledge about topics). Expert advice, the heart of the Web information space model, is specified using topics and relationships among topics (called metalinks), along the lines of the recently proposed topic maps. Topics and metalinks constitute metadata that describe the contents of the underlying HTML/XML Web resources. The metadata specification process is semiautomated, and it exploits XML DTDs (Document Type Definition) to allow domain-expert guided mapping of DTD elements to topics and metalinks. The expert advice is stored in an object-relational database management system (DBMS). To demonstrate the practicality and usability of the proposed Web information space model, we created a prototype expert advice repository of more than one million topics/metalinks for DBLP (Database and Logic Programming) Bibliography data set. We also present a query interface that provides sophisticated querying fa cilities for DBLP Bibliography resources using the expert advice repository.

- Abstract
- This article explores metadata quality issues in the creation and encoding of mappings or correlations of educational resources to K-12 achievement standards and the deployment of the metadata generated on the Semantic Web. The discussion is framed in terms of quality indicia derived from empirical studies of metadata in the Web environment. A number of forces at work in determining the quality of correlations metadata are examined including the nature of the emerging Semantic Web metadata ecosystem itself, the reliance on string values in metadata to identify achievement standards, the growing complexity of the standards environment, and the misalignment in terms of granularity between resource and declared objectives.

- Abstract
- The goal of the State Library of Queensland's Metadata Project is the deployment of metadata using the Dublin Core Metadata Element Set in the State Library' WWW Web pages. The deployment of metadata is expected to improve resource discovery by Internet users, through provision of index information (metadata) in State Library Web pages which is then available to search engines for indexing. The project is also an initial attempt to set standards for metadata deployment in queensland libraries Web pages

- Abstract
- Unter proactive Web design versteht man alle Maßnahmen, welche die Auffindbarkeit von Webseiten durch Suchmaschinen verbessern und bereits im Vorfeld oder im Moment der Publikation im WWW ergriffen werden können. Diese Maßnahmen reichen von der Registrierung einer Webseite bei Suchmaschinen über die Verknüpfung mit verwandten Web-Seiten und der aussagekräftigen Gestaltung von Titeln von Webseiten bis zur Verwendung von Metadaten

- Abstract
- Reports results of a study of 4 WWW search engines: AltaVista; Lycos; Excite and WebCrawler to collect data on Web objects on polymer chemistry. 1.037 Web objects were examined for data in 4 categories: document information; use of meta fields; use of images and use of chemical names. Issues raised included: whether to provide metadata elements for parts of entities or whole entities only, the use of metasyntax, problems in representation of special types of objects, and whether links should be considered when encoding metadata. Use of metafields was not widespread in the sample and knowledge of metafields in HTML varied greatly among Web object creators. The study formed part of a metadata project funded by the OCLC Library and Information Science Research Grant Program

- Abstract
- The main objective of the proposed high-level 'Visual Repository Definition Language' is to anbale advanced Web presentation of large amounts of exisitng heterogeneous information. Statements of the language serve to describe the desired structure of information repositories, which are composed of metadata entities encapsulating the original data. Such approach helps to to avoid the usual relocation and restructuring of data that occurs when providing Web access to it. The language has been designed to be useful even for inexperienced programmers. Its applicability is demonstrated by a real example, creating a repository of judicial opinions from publicly available raw data
