Data semantics workshop held by Microsoft

A two-day workshop on semantic web research issues was conducted by Microsoft in Redmond, WA from June 21-22. The issues discussed were concerned with data semantics and confidentiality on internet. The details are listed on their web page. In brief they discussed: about creation of data, methods to find data, confidentiality of information and control of information. They also discussed the probability of an open research project to discuss these issues. One of the interesting papers is "Evolving the Web Through Open Data" by Harry Halpin. He is the Chair of the W3C GRDDL Working Group.

In this paper he has mentioned the requirement for the standards and tools to assist authors in providing explicit semantics for the data. He also mentions that the current practice of implicit semantic data in natural language text is one of the methods of adding semantics to the web. He has also questioned the centralized unstructured search engine Google and has suggested a more powerful decentralized and structured web application for open data. We suggest that this can be achieved by providing an explicit syntax for the implicit semantic data. A mechanism such that natural language synonyms can be represented with an explicit code. The decentralization can be achieved with normative metadata for "open market" application. The normative metadata is the way of providing open data that is accessible. I.e. the search engines can read into the syntactic representation of the semantic data.

May be someday when semantic web is the only authentic procedure for publishing information then the thesaurus and dictionary will include the semantic codes for the natural language terms. There may be more than one code associated with a natural language term based on its ontology, similar to multiple meanings of a word according to the grammar rules and context. The web service provider can then refer these integrated vocabularies for normative metadata to provide open data. In order to define theses semantic codes for normative metadata the requirements are:

  1. standards to provide code definitions - we listed some in the previous post.

  2. standard terms for metadata representation - we have suggested that technology standards organizations must provide these, Example: DSL forum must provide normative metadata that can be used to describe DSL service.
