Content Curation for Spatial Experience of Architectural Heritage

Augmented space can be usefully applied to cultural heritage experience, because it is possible to experience physical space and acquire information at the same time. Experiencers can expand their experiences through virtual content while feeling the presence of relics or historic sites. The cultural heritage experiences currently implemented show simple forms in terms of their content and delivery method. Many cases repeatedly provide the same content regardless of the experience in a specific location. The present research, titled “the spatial-experience model of architectural heritage,” derived a methodology for construction of spatial experiences augmented by digital technology. Specifically, it deals with the problem of content curation and the limitations of the information system, which can be seen in the spatial-experience composition methods in the current digital heritage field. The information structure of the model was improved to enable spatial-oriented explanation of the expression of architectural heritage, which was insufficient in the existing metadata and ontology structures. The model has inference rules for creating an experience sequence and composes various combinations of experience content based on historical knowledge relationships. The model and reasoning rules were tested by applying them to real architectural heritage cases. Based on the test results, the role of the information structure in the spatial expression of its combination with content, as well as the possibility of diversification of sequence derivation, were considered. This research presents a syntax for construction of a semantic-rich environment while extending historical knowledge and spatial expression to the existing cultural heritage information system. In addition, by means of the content generator, which is a model for producing content using the extended descriptive language system, it is possible to create experience content in response to the increasing amount and demands of data. By applying the proposed model, it will be possible to quickly and easily derive various experience contents from the cultural heritage space, thereby reducing cost and time for content producers and providing an evolved spatial experience for consumers.
