Hello Nader,
Are you using GATE or KIM? I am getting confused!
I think KIM is doing exactly what you are trying to do. KIM uses GATE to
annotate documents against an Ontology (with our default pipeline or
your own). This process of annotation results is annotations that have
"inst" and "class" features that contain URIs. Then using these URIs,
that we got from the Ontology in the process of semantic annotation, KIM
will generate RDF. And finally we will store(infer and merge indeed)
that RDF in Sesame(in OWLIM indeed) as this is the natural place to
store RDF - OWLIM.
You can do all of the above with the populator tool in KIM.
And please read again my previous email.
Hope this helps,

Dear Anton,
Thanks alot for your efforts and the ontotext team efforts.
How can I interface the GATE with the Sesame as the input of the
Sesame program is RDF/XML files and the GATE doesn't output RDF files ??
Please I need a detailed answer and I read the user guides as
you recommended before.
Please reply as soon as possible.Thanks for your time.

Hello Nader,
a). First you can use the standard GATE or the GATE Developer that
comes with KIM.
When you process a document the result you get is an annotation set.
You either save that annotation set as XML(after you run the pipeline)
or use a datastore. When using a datastore the result is automatically
saved back in the datastore. Also with a datastores you can process a
higher volume of documents as documents are loaded in memory one by
one and this result in less memory management.
b). When we process a document we do information extraction, but
besides that we add the document to a full text search (FTS) index. In
KIM you can use different FTS indexers and the default one is Lucene.
Depending on the "running strategy" parameter we have different
behavior in KIM. With default running strategy we can proceed this way:
1. You call the SemanticAnnotationAPI.execute method to add semantic
annotations to your gate document (let's call it kdoc).
kdoc= SemanticAnnotationAPI.execute(kdoc);
Semantic annotations are these that have a URI in the ontology you are
using. To do that you need a processing resource that is capable of
doing that. In KIM pipeline it is called "Instance Generator".
2. Next step - you call the DocumentRepository.addDocumenet method.
By default this method will create FTS index. But besides that it will
generate RDF from using the semantic annotations from step 1. If you
do not have the semantic annotations it will only create a FTS index
and store the document (storage type is also configurable). The
generated RDF is stored and merged in OWLIM with data already
available in OWLIM.
You can use my answer here to achieve your specific goals.
Hope this helps and that I was able to explain it properly.

Dear Anton,
I want to know the importance of using GATE and Lucene in the KIM
platform in detail ?
How can I use each of them separtely to extarct the semantic
information from a HTML page or file ?
Also, what are the inputs and the outputs of each of them ?
Thanks for your time.

Hello Nader,
1. You need to supply a file that contains a SeRQL query. SeRQL is
a language similar to SPARQL and it is used for semantic queries.
I have attached such a file with a sample SeRQL query that
extracts all the companies that are loaded in OWLIM/KIM by default.
Your query must use the "construct" clause:
http://www.openrdf.org/doc/sesame/users/ch06.html#d0e1371
Sample command line:
kim\bin\tools>toolRdfExport.cmd query.txt result.rdf RDF/XML
2. I have attached a "2-Getting started.pdf" which is part of a
KIM-Guide which still has not been released. It should be
considered as a almost ready draft. You will find it useful in
order to comprehend what you can do with KIM in general. Check
point 5. By setting up the the Sesame UI you will be able to make
queries to the built-in OWLIM in KIM. Also the Sesame UI might
provide the functionality you need.
Hope this helps,

Dear sir,
First of all, thanks alot for your efforts.Second,
I have some questions:
1-I tried to use the RDF export tool but there was something
missing, I couldn't get the SeRQL file as I didn't know where
to find it and what's its extension, so can you tell me ??
2-I tried to use the OWLIM but I couldn't even operate it so
can I have more guidance to use it ??
My overall goal is as follows:
Taking any http page as an input and converting it from HTML
to RDF or OWL format so that I have the important information
in the HTML page but in the rdf format file.Then I build a
semantic application that uses this rdf files in a specific
domain: Mechanical for example .So what I need for now is a
program that converts from HTML to RDF .Also I need to know
how is this done if it's possible to be known.
Thanks alot for your time.Waiting for your reply as soon as
possible.

Nader Nassef Zaki

Hello Nader,
You can process documents and htmls with KIM and the resulting
RDF is stored in our built-in OWLIM database in KIM. You may
also try this tool:
http://ontotext.com/kim/doc/sys-doc/RDFExport.html. This tool
will export the RDF from OWLIM.

Hello Nader,
1 and 3: KIM does not provide functionality to get the
output in rdf/xml format. I don't recall older versions
being able to do this either. Maybe it is achievable
through the API. We haven't developed it in this direction.
2. There are a number of efforts to make public data
available in RDF format. There is also a big projects
which aims to connect the different disjoint datasets in
one large Knoledge Base. The project is called : Linked
Open Data
(http://esw.w3.org/topic/SweoIG/TaskForces/CommunityProjects/LinkingOpenData)
. In the data sets it uses you may find useful references
for your task
(http://esw.w3.org/topic/TaskForces/CommunityProjects/LinkingOpenData/DataSets).
For example: Geonames - http://www.geonames.org/ontology/ .
If you have your own data which is in a different format,
you may write your own custom tool to create RDF from it.
You will have to tie it to the ontology KIM uses by
default - PROTON (http://proton.semanticweb.org/). There
is a section in the documentation of KIM which will be
helpful : Creating Knowledge Bases and Ontologies .
Some tools for designing and viewing ontologies are :
Protege , Swoop, Top Braid Composer.
Hope this helps

Dear Philip,
I want to ask few questions about the Kim:
1-How can I get the output of the annotation as OWL
or RDF/XML files ?
2-You told me before to go to *kim/config/sesame.conf*
and edit the file by adding the namespaces of any new
knowledge base but how can I build this knowledge
base , can you explain in more detail ??
3-How can I get the older versions of the Kim platform ?
As I need precisely an API converting from HTML to OWL
or RDF based files and as I know the older versions of
the Kim platform did that.
Thanks alot for your time.Waiting for your reply.

You can use any
