Open Accessibility Data Interlinking

This paper presents the research of using Linked Open Data to enhance accessibility data for accessible travelling. Open accessibility data is the data related to the accessibility issues associated with geographical data, which could benefit people with disabilities and their special needs. With the aim of addressing the gap between users’ special needs and data, this paper presents the results of a survey of open accessibility data retrieved from four different sources in the UK. An ontology based data integration approach is proposed to interlink these datasets together to generate a linked open accessibility repository, which also links to other resources on the Linked Data Cloud. As a result, this research would not only enrich the open accessibility data, but also contribute to a novel framework to address accessibility information barriers by establishing a linked data repository for publishing, linking and consuming the open accessibility data.
