ABSTRACT

Considered a core component of business intelligence, a data warehouse deals with the management and integration of structured databases. The web has become a global data warehouse, though containing unstructured text rather than the structured content of data warehouses. Managing and integrating this huge amount of content that is intrinsically unstructured and heterogeneous in nature requires the ability to represent and store it in a manner that can be read and understood by computers and is highly scalable. Sir Tim Berners-Lee, the founder of the World Wide Web Consortium, envisioned the semantic web as a web of interconnected data, and the supporting semantic technologies made it a success. Since the introduction of linked data standards, there has been much more activity in employing semantic technologies everywhere that information is modeled. Semantic technologies can significantly improve the way we use large amounts of data. Potential benefits of semantic technologies include data integration from disparate data sources, interoperability, and efficient query answering.
