Semantic APIs: Scaling up towards the Semantic Web

Web information retrieval and knowledge discovery are undergoing changes. The size of the Web and the heterogeneity of web pages generate new challenges in meeting user needs. This paper investigates the different methods deployed that add semantics to web content: semantic tagging and semantic APIs. The research carried out investigates existing systems in each category, outlining their primary features and functionality. It then proposes a framework for the evaluation of semantic tagging based on the main requirements for information discovery and recommends a number of comparative assessments, ranging from basic product information and requirements’ analysis to the evaluation of the APIs information modelling functionality.
