Dear all,
(Note: I could not find the document, where your requirements regarding
the tracking of facts on the web are written, so I am giving a general
introduction to NIF. Please send me a link to the document that
specifies your need for tracing facts on the web, thanks)
I would like to point your attention to the URIs used in the NLP
Interchange Format (NIF).
NIF-URIs are quite easy to use, understand and implement. NIF has a
one-triple-per-annotation paradigm. The latest documentation can be
found here:
http://svn.aksw.org/papers/2012/WWW_NIF/public/string_ontology.pdf
The basic idea is to use URIs with hash fragment ids to annotate or mark
pages on the web:
An example is the first occurrence of "Semantic Web" on
http://www.w3.org/DesignIssues/LinkedData.html as highlighted here:
http://pcai042.informatik.uni-leipzig.de/~swp12-9/vorprojekt/index.php?anno…
Here is a NIF example for linking a part of the document to the DBpedia
entry of the Semantic Web:
<http://www.w3.org/DesignIssues/LinkedData.html#offset_717_729>
a str:StringInContext ;
sso:oen <http://dbpedia.org/resource/Semantic_Web> .
We are currently preparing a new draft for the spec 2.0. The old one can
be found here:
http://nlp2rdf.org/nif-1-0/
There are several EU projects that intend to use NIF. Furthermore, it is
easier for everybody, if we standardize a Web annotation format together.
Please give feedback of your use cases.
All the best,
Sebastian
