Abstract

The focus of this paper is the provision of terminology- and classification-based terminologies interoperability data via web services, initially using interoperability data based on the use of a Dewey Decimal Classification (DDC) spine, but with an aim to explore other possibilities in time, including the use of other spines. The High-Level Thesaurus Project (HILT) Phase IV developed pilot web services based on SRW/U, SOAP, and SKOS to deliver machine-readable terminology and crossterminology mappings data likely to be useful to information services wishing to enhance their subject search or browse services. It also developed an associated toolkit to help information services technical staff to embed HILT-related functionality within service interfaces. Several UK information services have created illustrative user interface enhancements using HILT functionality and these will demonstrate what is possible. HILT currently has the following subject schemes mounted and available: DDC, CAB, GCMD, HASSET, IPSV, LCSH, MeSH, NMR, SCAS, UNESCO, and AAT. It also has high level mappings between some of these schemes and DDC and some deeper pilot mappings available.

Abstract

Although service-oriented architectures go a long way toward providing interoperability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of ontologies. Then we analyze four basic models of semantic interoperability that differ in respect to their mapping between service descriptions and ontologies and in respect to where the evaluation of the integration logic is performed. We also provide some guidelines for selecting one of the possible interoperability models.

Abstract

Terminology registries (TRs) are a crucial element of the infrastructure required for resource discovery services, digital libraries, Linked Data, and semantic interoperability generally. They can make the content of knowledge organization systems (KOS) available both for human and machine access. The paper describes the attributes and functionality for a TR, based on a review of published literature, existing TRs, and a survey of experts. A domain model based on user tasks is constructed and a set of core metadata elements for use in TRs is proposed. Ideally, the TR should allow searching as well as browsing for a KOS, matching a user's search while also providing information about existing terminology services, accessible to both humans and machines. The issues surrounding metadata for KOS are also discussed, together with the rationale for different aspects and the importance of a core set of KOS metadata for future machine-based access; a possible core set of metadata elements is proposed. This is dealt with in terms of practical experience and in relation to the Dublin Core Application Profile.

Abstract

The JISC-funded HILT project is looking to make contact with staff in information services or projects interested in helping it test and refine its developing terminology services. The project is currently working to create pilot web services that will deliver machine-readable terminology and cross-terminology mappings data likely to be useful to information services wishing to extend or enhance the efficacy of their subject search or browse services. Based on SRW/U, SOAP, and SKOS, the HILT facilities, when fully operational, will permit such services to improve their own subject search and browse mechanisms by using HILT data in a fashion transparent to their users. On request, HILT will serve up machine-processable data on individual subject schemes (broader terms, narrower terms, hierarchy information, preferred and non-preferred terms, and so on) and interoperability data (usually intellectual or automated mappings between schemes, but the architecture allows for the use of other methods) - data that can be used to enhance user services. The project is also developing an associated toolkit that will help service technical staff to embed HILT-related functionality into their services. The primary aim is to serve JISC funded information services or services at JISC institutions, but information services outside the JISC domain may also find the proposed services useful and wish to participate in the test and refine process.

Abstract

This paper describes the basic concepts of terminology services and their role in information retrieval interfaces. Terminology services are consumed by other software applications using machine-to-machine protocols, rather than directly by end-users. An example of a terminology service is the pilot developed by the High Level Thesaurus (HILT) project which has successfully demonstrated its potential for enhancing subject retrieval in operational services. Examples of enhancements in three such services are given. The paper discusses the future development of terminology services in relation to the Semantic Web.

Abstract

This paper is about a better understanding of the structure and dynamics of science and the usage of these insights for compensating the typical problems that arises in metadata-driven Digital Libraries. Three science model driven retrieval services are presented: co-word analysis based query expansion, re-ranking via Bradfordizing and author centrality. The services are evaluated with relevance assessments from which two important implications emerge: (1) precision values of the retrieval services are the same or better than the tf-idf retrieval baseline and (2) each service retrieved a disjoint set of documents. The different services each favor quite other - but still relevant - documents than pure term-frequency based rankings. The proposed models and derived retrieval services therefore open up new viewpoints on the scientific knowledge space and provide an alternative framework to structure scholarly information systems.

Abstract

Amid the debates about whether folksonomies will supplant controlled vocabularies and whether the Library of Congress Subject Headings (LCSH) and Dewey Decimal Classification (DDC) system have outlived their usefulness, libraries, museums and other organizations continue to require efficient, effective access to controlled vocabularies for creating consistent metadata for their collections . In this article, we present an approach for using Web services to interact with controlled vocabularies. Services are implemented within a service-oriented architecture (SOA) framework. SOA is an approach to distributed computing where services are loosely coupled and discoverable on the network. A set of experimental services for controlled vocabularies is provided through the Microsoft Office (MS) Research task pane (a small window or sidebar that opens up next to Internet Explorer (IE) and other Microsoft Office applications). The research task pane is a built-in feature of IE when MS Office 2003 is loaded. The research pane enables a user to take advantage of a number of research and reference services accessible over the Internet. Web browsers, such as Mozilla Firefox and Opera, also provide sidebars which could be used to deliver similar, loosely-coupled Web services.

Abstract

Since several years it has been observed that information offered by different knowledge producing institutions on the internet is more and more interlinked. This tendency will increase, because the fragmented information offers on the internet make the retrieval of information difficult as even impossible. At the same time the quantity of information offered on the internet grows exponentially in Europe - and elsewhere - due to many digitization projects. Insofar as funding institutions base the acceptance of projects on the observation of certain documentation standards the knowledge created will be retrievable and will remain so for a longer time. Otherwise the retrieval of information will become a matter of chance due to the limits of fragmented, knowledge producing social groups.

Abstract

This article provides an overview of the work carried out by the HILT Project <http://hilt.cdlr.strath.ac.uk> in making recommendations towards interoperable subject access, or cross-searching and browsing distributed services amongst the archives, libraries, museums and electronic services sectors. The article details consensus achieved at the 19 June 2001 HILT Workshop and discusses the HILT Stakeholder Survey. In 1999 Péter Jascó wrote that "savvy searchers" are asking for direction. Three years later the scenario he describes, that of searchers cross-searching databases where the subject vocabulary used in each case is different, still rings true. Jascó states that, in many cases, databases do not offer the necessary aids required to use the "preferred terms of the subject-controlled vocabulary". The databases to which Jascó refers are Dialog and DataStar. However, the situation he describes applies as well to the area that HILT is researching: that of cross-searching and browsing by subject across databases and catalogues in archives, libraries, museums and online information services. So how does a user access information on a particular subject when it is indexed across a multitude of services under different, but quite often similar, subject terms? Also, if experienced searchers are having problems, what about novice searchers? As information professionals, it is our role to investigate such problems and recommend solutions. Although there is no hard empirical evidence one way or another, HILT participants agree that the problem for users attempting to search across databases is real. There is a strong likelihood that users are disadvantaged by the use of different subject terminology combined with a multitude of different practices taking place within the archive, library, museums and online communities. Arguably, failure to address this problem of interoperability undermines the value of cross-searching and browsing facilities, and wastes public money because relevant resources are 'hidden' from searchers. HILT is charged with analysing this broad problem through qualitative methods, with the main aim of presenting a set of recommendations on how to make it easier to cross-search and browse distributed services. Because this is a very large problem composed of many strands, HILT recognizes that any proposed solutions must address a host of issues. Recommended solutions must be affordable, sustainable, politically acceptable, useful, future-proof and international in scope. It also became clear to the HILT team that progress toward finding solutions to the interoperability problem could only be achieved through direct dialogue with other parties keen to solve this problem, and that the problem was as much about consensus building as it was about finding a solution. This article describes how HILT approached the cross-searching problem; how it investigated the nature of the problem, detailing results from the HILT Stakeholder Survey; and how it achieved consensus through the recent HILT Workshop.

Abstract

The HILT High Level Thesaurus Project aims to study and report an the problern of cross-searching and browsing by subject across a range of communities, services, and service or resource types in the UK given the wide range of subject schemes and associated practices in place in the communities in question (Libraries, Museums, Archives, and Internet Services) and taking the international context into consideration. The paper reports an progess to date, focusing particularly an the inter-community consensus reached at a recent Stakeholder Workshop.

Abstract

One of the major problems facing systems for Computer Aided Design (CAD), Architecture Engineering and Construction (AEC) and Geographic Information Systems (GIS) applications today is the lack of interoperability among the various systems. When integrating software applications, substantial di culties can arise in translating information from one application to the other. In this paper, we focus on semantic di culties that arise in software integration. Applications may use di erent terminologies to describe the same domain. Even when appli-cations use the same terminology, they often associate di erent semantics with the terms. This obstructs information exchange among applications. To cir-cumvent this obstacle, we need some way of explicitly specifying the semantics for each terminology in an unambiguous fashion. Ontologies can provide such specification. It will be the task of this paper to explain what ontologies are and how they can be used to facilitate interoperability between software systems used in computer aided design, architecture engineering and construction, and geographic information processing.

Abstract

Research information can be useful to science stake-holders for discovering, evaluating and planning research activities. In the Netherlands, the institute tasked with the stewardship of national research information is DANS (Data Archiving and Networked Services). DANS is the home of NARCIS, the national portal for research information, which uses a similarly named national research classification. The NARCIS Classification assigns symbols to represent the knowledge bases of contributing scholars. A recent research stream in knowledge organization known as comparative classification uses two or more classifications experimentally to generate empirical evidence about coverage of conceptual content, population of the classes, and economy of classification. This paper builds on that research in order to further understand the comparative impact of the NARCIS Classification alongside a classification designed specifically for information resources. Our six cases come from the DANS project Knowledge Organization System Observatory (KOSo), which itself is classified using the Information Coding Classification (ICC) created in 1982 by Ingetraut Dahlberg. ICC is considered to have the merits of universality, faceting, and a top-down approach. Results are exploratory, indicating that both classifications provide fairly precise coverage. The inflexibility of the NARCIS Classification makes it difficult to express complex concepts. The meta-ontological, epistemic stance of the ICC is apparent in all aspects of this study. Using the two together in the DANS KOS Observatory will provide users with both clarity of scientific positioning and ontological relativity.

Abstract

Even though ontologies are widely being used to enable interoperability in information-rich endeavours, there is currently no united framework for ontology interoperability itself. Surprisingly little of the state of the art in modularity and structuring, e.g. in software engineering, has been applied to ontology engineering so far. However, application areas like Ambient Assisted Living (AAL), which require synchronization and orchestration of interoperable services, are in dire need of safe and secure ontology interoperability. OntoIOp (Ontology Integration and Interoperability), a new international standard proposed in ISO/TC 37/SC 3, aims at filling this gap.

Abstract

Metadata related to cultural items such as literature, music and movies is a valuable resource that is currently exploited in many applications and services based on semantic web technologies. A vast amount of such information has been created by memory institutions in the last decades using different standard or ad hoc schemas, and a main challenge is to make this legacy data accessible as reusable semantic data. On one hand, this is a syntactic problem that can be solved by transforming to formats that are compatible with the tools and services used for semantic aware services. On the other hand, this is a semantic problem. Simply transforming from one format to another does not automatically enable semantic interoperability and legacy data often needs to be reinterpreted as well as transformed. The conceptual model in the Functional Requirements for Bibliographic Records, initially developed as a conceptual framework for library standards and systems, is a major step towards a shared semantic model of the products of artistic and intellectual endeavor of mankind. The model is generally accepted as sufficiently generic to serve as a conceptual framework for a broad range of cultural heritage metadata. Unfortunately, the existing large body of legacy data makes a transition to this model difficult. For instance, most bibliographic data is still only available in various MARC-based formats which is hard to render into reusable and meaningful semantic data. Making legacy bibliographic data accessible as semantic data is a complex problem that includes interpreting and transforming the information. In this article, we present our work on transforming and enhancing legacy bibliographic information into a representation where the structure and semantics of the FRBR model is explicit.

Abstract

XML will have a profound impact on the way data is exchanged on the Internet. An important feature of this language is the separation of content from presentation, which makes it easier to select and/or reformat the data. However, due to the likelihood of numerous industry and domain specific DTDs, those who wish to integrate information will still be faced with the problem of semantic interoperability. In this paper we discuss why this problem is not solved by XML, and then discuss why the Resource Description Framework is only a partial solution. We then present the SHOE language, which we feel has many of the features necessary to enable a semantic web, and describe an existing set of tools that make it easy to use the language.

Abstract

The CACAO Project (Cross-language Access to Catalogues and Online Libraries) has been designed to implement natural language processing and cross-language information retrieval techniques to provide cross-language access to information in libraries, a critical issue in the linguistically diverse European Union. This project report addresses two metadata-related challenges for the library community in this context: "false friends" (identical words having different meanings in different languages) and term ambiguity. The possible solutions involve enriching the metadata with attributes specifying language or the source authority file, or associating potential search terms to classes in a classification system. The European Library will evaluate an early implementation of this work in late 2008.

Abstract

Purpose - The general science portal "vascoda" merges structured, high-quality information collections from more than 40 providers on the basis of search engine technology (FAST) and a concept which treats semantic heterogeneity between different controlled vocabularies. First experiences with the portal show some weaknesses of this approach which come out in most metadata-driven Digital Libraries (DLs) or subject specific portals. The purpose of the paper is to propose models to reduce the semantic complexity in heterogeneous DLs. The aim is to introduce value-added services (treatment of term vagueness and document re-ranking) that gain a certain quality in DLs if they are combined with heterogeneity components established in the project "Competence Center Modeling and Treatment of Semantic Heterogeneity". Design/methodology/approach - Two methods, which are derived from scientometrics and network analysis, will be implemented with the objective to re-rank result sets by the following structural properties: the ranking of the results by core journals (so-called Bradfordizing) and ranking by centrality of authors in co-authorship networks. Findings - The methods, which will be implemented, focus on the query and on the result side of a search and are designed to positively influence each other. Conceptually, they will improve the search quality and guarantee that the most relevant documents in result sets will be ranked higher. Originality/value - The central impact of the paper focuses on the integration of three structural value-adding methods, which aim at reducing the semantic complexity represented in distributed DLs at several stages in the information retrieval process: query construction, search and ranking and re-ranking.

Abstract

Dublin Core recommends controlled terminology for the subject of a resource. Knowledge organization systems (KOS), such as classifications, gazetteers, taxonomies and thesauri, provide controlled vocabularies that organize and structure concepts for indexing, classifying, browsing and search. For example, a thesaurus employs a set of standard semantic relationships (ISO 2788, ISO 5964), and major thesauri have a large entry vocabulary of terms considered equivalent for retrieval purposes. Many KOS have been made available for Web-based access. However, they are often not fully integrated into indexing and search systems and the full potential for networked and programmatic access remains untapped. The lack of standardized access and interchange formats impedes wider use of KOS resources. We developed a Web demonstrator (www.comp.glam.ac.uk/~FACET/webdemo/) for the FACET project (www.comp.glam.ac.uk/~facet/facetproject.html) that explored thesaurus-based query expansion with the Getty Art and Architecture Thesaurus. A Web demonstrator was implemented via Active Server Pages (ASP) with server-side scripting and compiled server-side components for database access, and cascading style sheets for presentation. The browser-based interactive interface permits dynamic control of query term expansion. However, being based on a custom thesaurus representation and API, the techniques cannot be applied directly to thesauri in other formats on the Web. General programmatic access requires commonly agreed protocols, for example, building on Web and Grid services. The development of common KOS representation formats and service protocols are closely linked. Linda Hill and colleagues argued in 2002 for a general KOS service protocol from which protocols for specific types of KOS can be derived. Thus, in the future, a combination of thesaurus and query protocols might permit a thesaurus to be used with a choice of search tools on various kinds of databases. Service-oriented architectures bring an opportunity for moving toward a clearer separation of interface components from the underlying data sources. In our view, basing distributed protocol services on the atomic elements of thesaurus data structures and relationships is not necessarily the best approach because client operations that require multiple client-server calls would carry too much overhead. This would limit the interfaces that could be offered by applications following such a protocol. Advanced interactive interfaces require protocols that group primitive thesaurus data elements (via their relationships) into composites to achieve reasonable response.
