To instantiate Pinta in a domain, there are 5 steps: 1) Prepare appropriate ontologies and load them into a triple store. 2) Prepare the extractor service by creating gazetteers from the ontologies and deploying the service. 3) Prepare the KB service by modifying configuration files to point to the triple store and deploying the service. 4) Prepare the interface by modifying configuration files to point to the services and deploying Pinta. 5) Select content to annotate and input it into Pinta to make it available.

1. How to Instantiate Pinta in a
Domain

2. Aware of Components of Pinta
• Ontologies
• Services
– KB (service that retrieves knowledge axioms)
– Extractor (service that annotates text)
• Interface to view Pinta
• Textual content (e.g. comments, reviews etc)

3. Step:1 Prepare Ontologies
1. Select appropriate ontologies for your domain.
They must be RDF/OWL ontologies expressed in
RDF/XML, NT or N3 serialisations.
2. Load these ontologies in a Triple Store (Pinta
supports OWLIM 3.4+).Consult respective
manuals for triple stores on how to load
ontologies in a repository.
3. Make note of the repository URL.
4. Make note of all the possible prefix and
namespaces used by your ontologies.

4. Step 2: Prepare Extractor service
1. Use Gazetter program (Java) by providing the
location of where the ontologies are stored. This
will create Gazetters for the extractor service.
2. Place this Gazetters in Gaz directory of Extractor
service.
3. Create a WAR file of the Extractor directory and
name it “extractor”
4. Deploy War file on an application server(e.g.
Tomcat)
5. Make note of the address where the service is
running.

5. Step 3: Prepare KB service
• 1. Modify web.xml file from the kb service
folder to point to the Repository URL you
noted in Step 1.
• 2. Create a War file from the kb folder and
name it “kb”.
• 3. Deploy this WAR file on an application
server (e.g. Tomcat)
• 4. Make note of the address where the service
is running.

6. Step 4: Prepare Interface
• 1. Modify the dbconnect.php file (under Pinta
folder) to point to the location of “kb” and
“extractor” services (see step 2 and 3)
• 2. Modify functions.php file (under Pinta folder)
to all the possible prefix-namespace mappings
used within your selected ontologies. (see step 1)
• 3. Save the “pinta” folder on a web server of your
choice (e.g. apache)
• 4. Make note of URL where Pinta is running.

7. Step 5: Select & Annotate content
• 1. Select list of content that you would like to
provide as part of Pinta.
• 2. Go to “URL of Pinta”/annotatecontent.php
• 3. Input the text from your content one by one
and as you press “Submit” the content will be
immediately available in Pinta.

8. Time Estimates
• Selection of ontologies and Content
– This is very subjective task and depends on what type
of domain you are working (some have ready made
ontologies, some requires fusion or even creation
from scratch)
• Once you have ontologies and Content, set up
and deployment of Pinta
– For seasoned programmer ~ 1 day
– For medium level programmer ~ 2 -3 days
– For junior programmer ~ less than a week
