Provenance


 Across many fields involving complex computing, software systems are being augmented with workflow logging functionality.

The web lacks support for explaining information provenance. When web applications return answers, many users do not know what information sources were used, when they were updated, how reliable the source was, or what information was looked up versus derived.

The Semantic Web lacks support for explaining answers from web applications. When applications return answers, many users do not know what information sources were used, when they were updated, how reliable the source was, or what information was looked up versus derived.

The Semantic Web facilitates integrating partial knowledge and finding evidence for hypothesis from web knowledge sources. However, the appropriate level of granularity for tracking provenance of RDF graph remains in debate.

As the Semantic Web has enabled new application capabilities, new interaction modes arise and grow in importance. Applications can now not only retrieve results but also use term meanings to derive new results.

A new model of distributed, collaborative information evolution is emerging. As exemplified in Wikipedia, online collaborative information repositories are being generated, updated, and maintained by a large and diverse community of users.

The Semantic Web is being designed to enable automated reasoners to be used as core components in a wide variety of Web applications and services.
