The document discusses delivering accessible content from Social Semantic Information Sources (SSIS) through adaptive hypermedia. It outlines SSIS, their common components and models. It also discusses the Web Accessibility Initiative (WAI) and its goals of making web resources accessible to disabled users. Finally, it proposes using semantic metadata and annotations from SSIS as a dataset for adaptive hypermedia systems to improve accessibility without requiring manual data transformation. A prototype system called IKAR is presented as an example.
