Hi, (01)
I'm glad to find such project which is designed to express the subject
content of Web resources in terms of the interrelationship of subject
terms. Exactly with the same objective, I've worked on developing an
extended schema [3] of SKOS (Simple Knowledge Organization System) to
express the relationships which exist between two subject terms.
Definitely "isAbout" is very generic way of defining the subject matter of
the resources. In most cases there will be more than one subject
descriptors (keywords) for a resource. These descriptors can be joined
with one another with certain "relations". In [1] five basic relations
(facets) has been identified such as "Discipline", "Entity", "Property",
"Action" and Modifiers. (02)
The subject matter is expressed in natural language in any document
(resource). “The meaning of some information can be presented in a number
of ways i.e. in the form of many sentences. If we consider the various
sentences for the same information (surface structure), there should be a
unique deep structure for the various surface structures” (Prasad, 1993).
This unique deep structure constitutes of multiple facets. Ref 2 and ref.
3 are based on the work done by Prof. Ganesh Bhattacharyya on Subject
Indexing Languages [1]. (03)
With a brief introduction on my work, I would like to join the project.
Please refer to the references (some of the files I'm attaching in the
project site). (04)

> Hi All,
>
> You are cordially invited to comment or participate in the UMBEL (Upper
> Mapping and Binding Exchange Layer) project.
>
> UMBEL is a lightweight way to describe the subject(s) of Web content,
> akin to the relationship "isAbout". It is meant to work universally with
> HTML, tagging, microformats or other standard practices, including
> various RDF schemas and more formal ontologies. Its reference subject
> 'backbone' is derived from the intersection of common subjects found on
> popularly used Web sites and other accepted subject references.
>
> UMBEL is very simple with few ambitions. It is merely a reference 'bag
> of subjects' to help relate Web data sets to one another.
>
> UMBEL makes no presumptions to replace formal domain or upper
> ontologies, has little or no inferential power, and makes no assumptions
> about the means to describe or serialize the underlying data. UMBEL is
> meant to work with data sets ranging from RSS and Atom feeds to tagging,
> microformats, RDF, existing schema and other data and metadata models.
> UMBEL's development is being backed by a number of leading open data
> efforts and entities.
>
> In addition to its core reference subjects, the UMBEL project will be
> providing look up, query, registration, pinging, and related services.
> The project is completely open under a community process with all
> products available via Creative Commons licenses.
>
> The initial project site is at http://www.umbel.org, including an
> introduction (http://www.umbel.org/intro.xhtml) (the best place to
> start!) and the draft project specification
> (http://www.umbel.org/proposal.xhtml).
>
> A mailing list you can monitor or join is at
> http://groups.google.com/group/umbel-ontology.
>
> We welcome and invite your participation!
>
> Best regards,
