  Wu, Y. ; Lehman, A. ; Dunaway, D:J.: Evaluations of a large topic map as a knowledge organization tool for supporting self-regulated learning.
  In: Knowledge organization. 42(2015) no.6, S.386-398.
  
  Abstract: A large topic map was created to facilitate understanding of the impacts of the 2010 Gulf of Mexico Oil Spill Incident. The topic map has both a text and graphical interface, which complement each other. A formative evaluation and two summative evaluations were conducted, as qualitative studies, to assess the usefulness and usability of the large topic maps for facilitating self-regulated learning. The topic maps were found useful for knowledge fusion and discovery, and can be useful when undertaking interdisciplinary and multidisciplinary research. Users reported some usability issues about the graphical topic map, including information overload and cluttered display of topics when displaying large number of topics and their associated topics. The text topic map was found easier to use due to displaying topics, relationships and references in a linear view.

  Wlodarczyk, B.: Topic map as a method for the development of subject headings vocabulary : an introduction to the project of the National Library of Poland.
  In: Cataloging and classification quarterly. 51(2013) no.7, S.816-829.
  
  Abstract: Subject searches in the National Library of Poland catalog are still comprised of a significant number of all searches, but understanding and exploration of the National Library of Poland Subject Headings causes many problems, not only for the end-users, but also for many librarians. Another problem in the National Library of Poland is the insufficient use of relationships between the terms. The solution could be a properly designed Web application based on a topic map using appropriate visualization that supports indexing and information retrieval in the National Library of Poland. The article presents the main stages of a planned project.

  Baião Salgado Silva, G. ; Lima, G.Â. Borém de Oliveira: Using topic maps in establishing compatibility of semantically structured hypertext contents.
  In: Knowledge organization. 39(2012) no.6, S.432-445.
  
  Abstract: Considering the characteristics of hypertext systems and problems such as cognitive overload and the disorientation of users, this project studies subject hypertext documents that have undergone conceptual structuring using facets for content representation and improvement of information retrieval during navigation. The main objective was to assess the possibility of the application of topic map technology for automating the compatibilization process of these structures. For this purpose, two dissertations from the UFMG Information Science Post-Graduation Program were adopted as samples. Both dissertations had been duly analyzed and structured on the MHTX (Hypertextual Map) prototype database. The faceted structures of both dissertations, which had been represented in conceptual maps, were then converted into topic maps. It was then possible to use the merge property of the topic maps to promote the semantic interrelationship between the maps and, consequently, between the hypertextual information resources proper. The merge results were then analyzed in the light of theories dealing with the compatibilization of languages developed within the realm of information technology and librarianship from the 1960s on. The main goals accomplished were: (a) the detailed conceptualization of the merge process of the topic maps, considering the possible compatibilization levels and the applicability of this technology in the integration of faceted structures; and (b) the production of a detailed sequence of steps that may be used in the implementation of topic maps based on faceted structures.

  Melgar Estrada, L.M.: Topic maps from a knowledge organization perspective.
  In: Knowledge organization. 38(2011) no.1, S.43-61.
  
  Abstract: This article comprises a literature review and conceptual analysis of Topic Maps-the ISO standard for representing information about the structure of information resources-according to the principles of Knowledge Organization (KO). Using the main principles from this discipline, the study shows how Topic Maps is proposed as an ontology model independent of technology. Topic Maps constitutes a 'bibliographic' meta-language able to represent, extend, and integrate almost all existing Knowledge Organization Systems (KOS) in a standards-based generic model applicable to digital content and to the Web. This report also presents an inventory of the current applications of Topic Maps in Libraries, Archives, and Museums (LAM), as well as in the Digital Humanities. Finally, some directions for further research are suggested, which relate Topic Maps to the main research trends in KO.

  Bold, N. ; Kim, W.-J. ; Yang, J.-D.: Converting object-based thesauri into XML Topic Maps.
  In: 2010 2nd International Conference on Education Technology and Computer (ICETC). Piscataway, NJ : IEEE, 2010. S.V2:102-106.
  
  Abstract: Constructing ontology is considerably time consuming process in general. Since there are a vast amount of thesauri currently available, it may be a feasible solution to exploit thesauri, when constructing ontology in a short period of time. This paper designs and implements a XTM (XML Topic Maps) code converter generating XTM coded ontology from an object based thesaurus. It is an extended thesaurus, which enriches the conventional thesauri with user defined associations, a notion of instances and occurrences associated with them. The reason we adopt XTM is that it is a verified and practical methodology to semantically reorganize the conceptual structure of extant web applications with minimal effort. Moreover, since XTM is conceptually similar to our object based thesauri, recommendation and inference mechanism already developed in our system could be easily applied to the generated XTM ontology. To show that the XTM ontology is correct, we also verify it with onto pia Omnigator and Vizigator, the components of Ontopia Knowledge Suite (OKS) tool.

  Pepper, S.: Topic maps.
  In: Encyclopedia of library and information sciences. 3rd ed. Ed.: M.J. Bates. London : Taylor & Francis, 2009. S.xx-xx.
  
  Abstract: Topic Maps is an international standard technology for describing knowledge structures and using them to improve the findability of information. It is based on a formal model that subsumes those of traditional finding aids such as indexes, glossaries, and thesauri, and extends them to cater for the additional complexities of digital information. Topic Maps is increasingly used in enterprise information integration, knowledge management, e-learning, and digital libraries, and as the foundation for Web-based information delivery solutions. This entry provides a comprehensive treatment of the core concepts, as well as describing the background and current status of the standard and its relationship to traditional knowledge organization techniques.

  Yi, M.: Information organization and retrieval using a topic maps-based ontology : results of a task-based evaluation.
  In: Journal of the American Society for Information Science and Technology. 59(2008) no.12, S.1898-1911.
  
  Abstract: As information becomes richer and more complex, alternative information-organization methods are needed to more effectively and efficiently retrieve information from various systems, including the Web. The objective of this study is to explore how a Topic Maps-based ontology approach affects users' searching performance. Forty participants participated in a task-based evaluation where two dependent variables, recall and search time, were measured. The results of this study indicate that a Topic Maps-based ontology information retrieval (TOIR) system has a significant and positive effect on both recall and search time, compared to a thesaurus-based information retrieval (TIR) system. These results suggest that the inclusion of a Topic Maps-based ontology is a beneficial approach to take when designing information retrieval systems.

  Iglesias, E. ; Hye, S.S.: Topic maps and the ILS : an undelivered promise.
  In: Library hi tech. 26(2008) no.1, S.12-18.
  
  Abstract: Purpose - The purpose of this paper is to provide an overview of the current use of topic maps in the library field, how they might be integrated into the ILS structure and some of the inherent challenges in trying to transform MARC data. Design/methodology/approach - A review of available literature was conducted as well as e-mail interviews with researchers and vendors in the field. An introduction to some of the basic concepts quickly leads into a recap of some of the possibilities that have been tried with this technology in the library field. Specific examples of the use of the XML standard XTM are given as well as some theoretical possibilities discussed. Finally some thought is given to where this technology will fit into the ILS. Findings - The paper finds that more work needs to be done by vendors and libraries in structuring data to allow for easier transformation. Research limitations/implications - This study was a limited overview. The lack of training materials and software make topics maps have an unnecessarily high barrier to entry. Practical implications - This paper points a way for further research and a need for basic tools and training geared towards the library community. Originality/value - This paper attempts to address some of the potential and challenges associated with using topic maps in a library environment, especially as part of an ILS.

  In: Metadata for semantic and social applications : proceedings of the International Conference on Dublin Core and Metadata Applications, Berlin, 22 - 26 September 2008, DC 2008: Berlin, Germany / ed. by Jane Greenberg and Wolfgang Klas. Göttingen : Univ.-Verl., 2008. S.34-42.
  
  Abstract: This paper presents an approach for integrating multiple sources of semantics for the creating metadata. A new framework is proposed to define topics and themes with both manually and automatically generated terms. The automatically generated terms include: terms from a semantic analysis of the collections and terms from previous user's queries. An interface is developed to facilitate the creation and use of such topics and themes for metadata creation. The framework and the interface promote human-computer collaboration in metadata creation. Several principles underlying such approach are also discussed.

  Siebers, Q.H.J.F.: Implementing inference rules in the Topic maps model.
  In: http://www.unimaas.nl/games/files/bsc/Siebers_BSc-paper.pdf.
  
  Abstract: This paper supplies a theoretical approach on implementing inference rules in the Topic Maps model. Topic Maps is an ISO standard that allows for the modeling and representation of knowledge in an interchangeable form, that can be extended by inference rules. These rules specify conditions for inferrable facts. Any implementation requires a syntax for storage in a file, a storage model and method for processing and a system to keep track of changes in the inferred facts. The most flexible and optimisable storage model is a controlled cache, giving options for processing. Keeping track of changes is done by listeners. One of the most powerful applications of inference rules in Topic Maps is interoperability. By mapping ontologies to each other using inference rules as converter, it is possible to exchange extendable knowledge. Any implementation must choose methods and options optimized for the system it runs on, with the facilities available. Further research is required to analyze optimization problems between options.

  Cregan, A.: ¬An OWL DL construction for the ISO Topic Map Data Model.
  In: http://xml.coverpages.org/CreganTMs-OWL200505.pdf.
  
  Abstract: Both Topic Maps and the W3C Semantic Web technologies are meta-level semantic maps describing relationships between information resources. Previous attempts at interoperability between XTM Topic Maps and RDF have proved problematic. The ISO's drafting of an explicit Topic Map Data Model [TMDM 05] combined with the advent of the W3C's XML and RDFbased Description Logic-equivalent Web Ontology Language [OWLDL 04] now provides the means for the construction of an unambiguous semantic model to represent Topic Maps, in a form that is equivalent to a Description Logic representation. This paper describes the construction of the proposed TMDM ISO Topic Map Standard in OWL DL (Description Logic equivalent) form. The construction is claimed to exactly match the features of the proposed TMDM. The intention is that the topic map constructs described herein, once officially published on the world-wide web, may be used by Topic Map authors to construct their Topic Maps in OWL DL. The advantage of OWL DL Topic Map construction over XTM, the existing XML-based DTD standard, is that OWL DL allows many constraints to be explicitly stated. OWL DL's suite of tools, although currently still somewhat immature, will provide the means for both querying and enforcing constraints. This goes a long way towards fulfilling the requirements for a Topic Map Query Language (TMQL) and Constraint Language (TMCL), which the Topic Map Community may choose to expend effort on extending. Additionally, OWL DL has a clearly defined formal semantics (Description Logic ref)

  Garshol, L.M.: Metadata? Thesauri? Taxonomies? Topic Maps! : making sense of it all.
  In: Journal of information science. 30(2005) no.4, S.378-391.
  
  Abstract: The task of an information architect is to create web sites where users can actually find the information they are looking for. As the ocean of information rises and leaves what we seek ever more deeply buried in what we don't seek, this discipline becomes ever more relevant. Information architecture involves many different aspects of web site creation and organization, but its principal tools are information organization techniques developed in other disciplines. Most of these techniques come from library science, such as thesauri, taxonomies, and faceted classification. Topic maps are a relative newcomer to this area and bring with them the promise of better-organized web sites, compared to what is possible with existing techniques. However, it is not generally understood how topic maps relate to the traditional techniques, and what advantages and disadvantages they have, compared to these techniques. The aim of this paper is to help build a better understanding of these issues.

  Abstract: Verschiedene Szenarien in Groupware-basierten Umgebungen verdeutlichen die Probleme, Wissensstrukturen im Allgemeinen und organisationale Wissensstrukturen im Speziellen zu identifizieren. Durch den Einsatz von Topic Maps, definiert im ISOStandard "ISO/IEC 13250 Topic Maps", in Groupware-basierten organisationalen Wissensbasen wird es möglich, die Lücke zwischen Wissen und Information zu schließen. In diesem Beitrag werden die Ziele des Forschungsprojektes K-Discovery - der Einsatz von Topic Maps in Groupware-basierten Umgebungen - vorgestellt. Aufbauend auf diesen Zielen wird ein Architekturmodell sowie zwei Implementationsansätze präsentiert, in dem durch den Einsatz von Topic Maps in einer prozessorientierten GroupwareUmgebung Wissensstrukturen generiert werden. Der Beitrag schließt mit einigen abschließenden Ausführungen.

  Toms, E.G. ; Taves, A.R.: Measuring user perceptions of Web site reputation.
  In: Information processing and management. 40(2004) no.2, S.291-317.
  
  Abstract: In this study, we compare a search tool, TOPIC, with three other widely used tools that retrieve information from the Web: AltaVista, Google, and Lycos. These tools use different techniques for outputting and ranking Web sites: external link structure (TOPIC and Google) and semantic content analysis (AltaVista and Lycos). TOPIC purports to output, and highly rank within its hit list, reputable Web sites for searched topics. In this study, 80 participants reviewed the output (i.e., highly ranked sites) from each tool and assessed the quality of retrieved sites. The 4800 individual assessments of 240 sites that represent 12 topics indicated that Google tends to identify and highly rank significantly more reputable Web sites than TOPIC, which, in turn, outputs more than AltaVista and Lycos, but this was not consistent from topic to topic. Metrics derived from reputation research were used in the assessment and a factor analysis was employed to identify a key factor, which we call 'repute'. The results of this research include insight into the factors that Web users consider in formulating perceptions of Web site reputation, and insight into which search tools are outputting reputable sites for Web users. Our findings, we believe, have implications for Web users and suggest the need for future research to assess the relationship between Web page characteristics and their perceived reputation.

  Abstract: Topic Maps auf der einen Seite und das Programm Concepto auf der anderen Seite werden beschrieben. Mt Topic Maps können Wortnetze und einfache Satzstrukturen dargestellt werden. Concepto dient zur Erfassung, Bearbeitung und Visualisierung von Wortschatz und Strukturen. Es unterstützt ein Wortmodell, bei dem die verschiedenen Lesarten eines Wortes erfasst und einfachen, formalsprachlichen Begriffen zugewiesen werden können. Die Funktionen beider Systeme werden verglichen. Es wird dargestellt, was an Topic Maps und an Concepto ergänzt werden müsste, wenn beide Systeme einen kompatiblen, wechselseitigen Datenaustausch zulassen sollen. Diese Erweiterungen würden die Anwendbarkeit der Systeme noch interessanter machen.
