  • Thesauruses and Ontologies
    Thesauruses and ontologies Silvia Arano Citación recomendada: Silvia Arano. Thesauruses and ontologies [en linea]. "Hipertext.net", num. 3, 2005. <http://www.hipertext.net> [Consulted: 12 feb. 2007]. 1. Introduction During the past few years, the information representation and retrieval sector in the area of Documentation and Biblioteconomy has had to assume the important repercussions of the Internet and its associated technologies, and in particular, the World Wide Web (WWW). Technological modifications arising from these important changes are leading to the gradual digitalisation of the information representation and retrieval sector, affecting information artefacts, representation and retrieval tools and user requirements. In the light of this growing context of digitalisation, diverse information representation and retrieval tools exist, which must be studied in addition to diverse fields of knowledge in which these tools have originated: Linguistics, Artificial Intelligence, Documentation, Linguistic Engineering... Hence, in specialised literature, analyses are performed on information representation and retrieval tools, taxonomies, classification systems, computational lexicons, lexical databases, thesauruses, titles lists, knowledge bases, conceptual maps, ontologies, synonym rings and semantic networks, among others. Among this wide spectrum of information representation and retrieval tools are thesauruses and ontologies, which are most often linked in bibliography, even though they come from completely different disciplinary areas. However, the conceptualisation applied by authors to the terms "thesaurus" and "ontology" is quite diverse, and sometimes authors confuse, oppose, complement or overlap both these concepts. The overall objective of the present article [ 1] is to establish the relationship between the concepts of thesaurus and ontology in the Documentation and Biblioteconomy field. Two specific objectives have been established for this purpose.

  • Is a SPARQL Endpoint a Good Way to Manage Nursing Documentation
    Is a SPARQL Endpoint a Good way to Manage Nursing Documentation Is a SPARQL Endpoint a good way to Manage Nursing Documentation by Muhammad Aslam Supervisor: Associate Professor Jan Pettersen Nytun Project report for Master Thesis in Information & Communication Technology IKT 590 in Spring 2014 University of Agder Faculty of Engineering and Science Grimstad, 2 June 2014 Status: Final Keywords: Semantic Web, Ontology, Jena, SPARQL, Triple Store, Relational Database Page 1 of 86 Is a SPARQL Endpoint a Good way to Manage Nursing Documentation Abstract. In Semantic Web there are different technologies available, among these technologies ontologies are considered a basic technology to promote semantic management and activities. An ontology is capable to exhibits a common, shareable and reusable view of a specific application domain, and they give meaning to information structures that are exchanged by information systems [63]. In this project our main goal is to develop an application that helps to store and manage the patient related clinical data. For this reason first we made an ontology, in ontology we add some patient related records. After that we made a Java application in which we read this ontology by the help of Jena. Then we checked this application with some other database solutions such as Triple Store (Jena TDB) and Relational database (Jena SDB). After that we performed SPARQL Queries to get results that reads from databases we have used, on the basis of results that we received after performing SPARQL Queries, we made an analysis on the performance and efficiency of databases. In these results we found that Triple Stores (Jena TDB) have capabilities to response very fast among other databases.

  • A Survey of Geospatial Semantic Web for Cultural Heritage
    heritage Review A Survey of Geospatial Semantic Web for Cultural Heritage Ikrom Nishanbaev 1,* , Erik Champion 1 and David A. McMeekin 2 1 School of Media, Creative Arts, and Social Inquiry, Curtin University, Perth, WA 6845, Australia; [email protected] 2 School of Earth and Planetary Sciences, Curtin University, Perth, WA 6845, Australia; [email protected] * Correspondence: [email protected] Received: 23 April 2019; Accepted: 16 May 2019; Published: 20 May 2019 Abstract: The amount of digital cultural heritage data produced by cultural heritage institutions is growing rapidly. Digital cultural heritage repositories have therefore become an efficient and effective way to disseminate and exploit digital cultural heritage data. However, many digital cultural heritage repositories worldwide share technical challenges such as data integration and interoperability among national and regional digital cultural heritage repositories. The result is dispersed and poorly-linked cultured heritage data, backed by non-standardized search interfaces, which thwart users’ attempts to contextualize information from distributed repositories. A recently introduced geospatial semantic web is being adopted by a great many new and existing digital cultural heritage repositories to overcome these challenges. However, no one has yet conducted a conceptual survey of the geospatial semantic web concepts for a cultural heritage audience. A conceptual survey of these concepts pertinent to the cultural heritage field is, therefore, needed. Such a survey equips cultural heritage professionals and practitioners with an overview of all the necessary tools, and free and open source semantic web and geospatial semantic web platforms that can be used to implement geospatial semantic web-based cultural heritage repositories.

  • What Are Controlled Vocabularies?
    2. What Are Controlled Vocabularies? A controlled vocabulary is an organized arrangement of words and phrases used to index content and/or to retrieve content through browsing or searching. It typically includes preferred and variant terms and has a defined scope or describes a specific domain. 2.1. Purpose of Controlled Vocabularies The purpose of controlled vocabularies is to organize information and to provide terminology to catalog and retrieve information. While capturing the richness of variant terms, controlled vocabularies also promote consistency in preferred terms and the assignment of the same terms to similar content. Given that a shared goal of the cultural heritage community is to improve access to visual arts and material culture information, controlled vocabularies are essential. They are necessary at the indexing phase because without them catalogers will not consistently use the same term to refer to the same person, place, or thing. In the retrieval process, various end users may use different synonyms or more generic terms to refer to a given concept. End users are often not specialists and thus need to be guided because they may not know the correct term. The most important functions of a controlled vocabulary are to gather together variant terms and synonyms for concepts and to link concepts in a logical order or sort them into categories. Are a rose window and a Catherine wheel the same thing? How is pot-metal glass related to the more general term stained glass? The links and relationships in a controlled vocabulary ensure that these connections are defined and maintained, for both cataloging and retrieval.

  • Taxonomy Directed Folksonomies
    2nd Version Date : 19/06/2007 TAXONOMY DIRECTED FOLKSONOMIES Integrating user tagging and controlled vocabularies for Australian education networks Sarah Hayman and Nick Lothian education.au Adelaide Australia Meeting: 157 Classification and Indexing Simultaneous Interpretation: No WORLD LIBRARY AND INFORMATION CONGRESS: 73RD IFLA GENERAL CONFERENCE AND COUNCIL 19-23 August 2007, Durban, South Africa http://www.ifla.org/iv/ifla73/index.htm 1 Abstract What is the role of controlled vocabulary in a Web 2.0 world? Can we have the best of both worlds: balancing folksonomies and controlled vocabularies to help communities of users find and share information and resources most relevant to them? education.au develops and manages Australian online services for education and training. Its goal is to bring people, learning and technology together. education.au projects are increasingly involved in exploring the use of Web 2.0 developments building on user ideas, knowledge and experience, and how these might be integrated with existing information management systems. This paper presents work being undertaken in this area, particularly in relation to controlled vocabularies, and discusses the challenges faced. Education Network Australia (edna) is a leading online resource collection and collaborative network for education, with an extensive repository of selected educational resources with metadata created by educators and information specialists. It uses controlled vocabularies for metadata creation and searching, where users receive suggested related terms from an education thesaurus, with their results. We recognise that no formal thesaurus can keep pace with user needs so are interested in exploiting the power of folksonomies. We describe a proof of concept project to develop community contributions to managing information and resources, using Taxonomy-Directed Folksonomy.

  • Controlled Vocabulary and Folksonomies
    Controlled Vocabulary and Folksonomies Louise Spiteri School of Information Management What are folksonomies? Folksonomies (known also as “social classifications”) are user created metadata. They are grassroots community classification of digital assets. The term “folksonomy” was created by Thomas Vander Val and represents a merging of the terms “folk” and “taxonomy.” One form of explicit user created metadata was popularized in the late 1990s with link-focused websites called weblogs. Where are folksonomies found? Folksonomies are found in social bookmarks managers such as Del.icio.us (http://del.icio.us/) and Furl (http://www.furl.net/), which allow users to: Add bookmarks of sites they like to their personal collections of links Organize and categorize these sites by adding their own terms, or tags Share this collection with other people with the same interests. The tags are used to collocate bookmarks: (a) within a user’s collection; and (b) across the entire system, e.g., the page http://del.icio.us/tag/blogging will show all bookmarks that are tagged with “blogging” by any user. Inter-term relationships There are no clearly defined relations between and among the terms in the vocabulary, unlike formal taxonomies and classification schemes, where there are multiple kinds of explicit relationships (e.g., broader, narrower, and related terms) between and among terms. Folksonomies are simply the set of terms that a group of users tagged content with; they are not a predetermined set of classification terms or labels.
