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.
