Workshop on Ontology & Rich Semantics

Workshop on Ontology and Rich Semantics: Frameworks and Application Date of event: Mon, 26th Nov. 2018, 9:30am to 4:00pm Venue: Wee Kim Wee School of Communication & Information, Nanyang Technological University, Singapore Organisers: Dr Chris Khoo, Dr Robert B Allen, & Dr Shigeo Sugimoto For more information: see blog page, or Facebook event . Description: Explicit rich representations of domain knowledge, models, processes, historical development, and argumentation are important to support e-science, e-social science and digital humanities research. Ontologies define concept hierarchies and identify important types of relations between concepts as well as entities of interest. However, to support e-research as well as real applications, ontologies need to go beyond simple semantics to include representation of complex structures and systems, dynamic models and processes, flow of temporal events, as well as discourse structure, evolution of knowledge, argumentation and information across types of documents and media. This workshop will explore frameworks...

Article: Task-based navigation of a taxonomy interface to a digital repository

Khoo, C.S.G., Wang, Z., & Chaudhry, A.S. (2012). Task-based navigation of a taxonomy interface to a digital repository. Information Research, 17(4). (Available at: http://informationr.net/ir/17-4/infres174.html) Abstract Introduction. This is a study of hierarchical navigation; how users browse a taxonomy-based interface to an organizational repository to locate information resources. The study is part of a project to develop a taxonomy for an library and information science department to organize resources and support user browsing in a digital repository. Method. The data collection was carried out using task-based navigation exercises with twenty-two participants. A cognitive framework of hierarchical navigation is proposed, involving the cognitive process of matching context, topic and/or resource type concepts to taxonomy categories. Results. Though users often use the topic concept in making navigation choices, they sometimes make use of context and resource-type concepts. Users infer a variety of relationships between a task concept and a taxonomy category, including...

Lee, L.-P., Liu, H.-W., Shi, D.-M., Khoo, C.S.G., & Pang, N. (2013). Developing a framework for analyzing organizational stories. In The 5th International Conference on Asia-Pacific Library and Information Education and Practice (A-LIEP 2013): Proceedings (pp. 260-271). Khon Kaen City, Thailand: University of Khon Kaen, Faculty of Humanties and Social Sciences. Summary: Stories are becoming an increasingly important knowledge management and knowledge sharing tool to communicate ideas, values and experiences both to internal organizational members and to external stakeholders. This paper reports an initial effort to develop a framework for the analysis of organizational stories. The framework has two major parts: the story framework comprising six elements, and the interaction/communication framework. The six elements of a story are: Background to the story—the context in the story itself, the prior situation and events leading up to the story. Core of the story—the essence or summary of the story, the...

In Proceedings of the 2013 Digital Heritage International Congress, 28 Oct-1 Nov 2013, Marseille, France (IEEE catalog no. CFP1308W-USB, pp. 297-305).

The study sought to find out users’ expectations of the content of the portal, how they search and browse the portal, and what they learn about particular historical or cultural topics from reading postings in the portal. The goal is to derive a taxonomy to organize the portals’ content for browsing and learning. For this initial study, 12 Singapore citizens were interviewed to find out what topics...
