Annotating using DBPedia ontology
Hi,
Until now I used my ontology when I wanted to annotate document (or text).
Now I would like to use DBPedia ontology. Do I have to download ontology
and configure Stanbol like I did before, using
curl -v -X POST -H "Content-Type: application/rdf+xml" --data
"@acm-ccs_proton.owl" http://localhost:8080/entityhub/entity
or there is another procedure? Does Stanbol use DBPedia ontology by
default, or I have to configure something similar like when I use another
ontology?

Thank you Rupert.
I will try these options. I didn't have problems like this with Linux. Does
this have something to do with Windows?
Best,
Srecko

Hi Srecko
On [1] is mentioned that setting the system property
java.nio.debug=pipe
might help to get some additional information on why this is happening.
In addition I found [2] that says that the system properties
org.apache.felix.http.nio
org.apache.felix.https.nio
can be used to deactivate the use of NIO for the http and https service of
Apache Felix.

Hi Rupert,
I thought so, but I checked firewall and turned it off. You are right, it is
Windows now. I don't have problems like this one when I use Linux, but now I
need Windows.
I don't have another firewall then default one, and that one is turned off.
Best,
Srecko

Hi Srecko
I googled for this exception and 90%+ of all pages had to do with Firewall
configurations on Windows machines.
The best description I found was on
http://weblogs.java.net/blog/binod/archive/2006/12/glassfish_and_w.html
About the enhancement result you posted: This is what the result looks like
if only the Metaxa and the LangId Engine are active. So I assume that the
other engines where not activated correctly. Maybe because of the
IOException
Can you please check if you use a Firewall that could cause this? Are you
running Stanbol on Windos?

Re: Annotating using DBPedia ontology
Posted by srecko joksimovic <sr...@gmail.com>.
Hi Rupert,
There is also problem with web page. That means that text works just fine,
but I have problems with documents and web pages. When I try to annotate
web page, this is what I get:
http://en.wikipedia.org/wiki/Semantic_Web // URL to annotate
**** 174030 // file length - this means that you were right about
GetMethod, and it works now
174030 text/html // file length and content type just before calling
annotate method
ERROR <html>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>

Can you please open a jira issue and attach the stacktrace as a text

RE: Annotating using DBPedia ontology
Posted by Srecko Joksimovic <sr...@gmail.com>.
Hi,
Recently I asked about annotating web resource and it was bug that you
solved. Now something similar happened when I tried to annotate this URL
http://en.wikipedia.org/wiki/Software_design_pattern
This is the output I got:
http://en.wikipedia.org/wiki/Software_design_pattern

Subject: Re: Annotating using DBPedia ontology
Hi,
Thank you for your time, and answer.
Could you please explain me how do you extract annotated concepts from
generated model? I usually generate RDF output, parse SPARQL query and
process the output. Could you send me an example based on one of these two
documents you sent to me?
Best,
Srecko

Hi,
Both of the PDF documents you sent work fine for us and the annotations look
as expected. Find attached output from our test, for the 22 pages doc as
well as for the 558 pages doc.
I have no explanation of why you apparently got different annotations.
Best regards,
Walter

I have to say that everything works great for string, txt and doc files, as

I attached results for this document
http://www.gtbit.org/downloads/dwdmsem6/dwdmsem6lman.pdf. I didn't access
document using this URL, but downloaded and access it as C:\temp\weka.pdf.
I get correct answer, I mean, there are no errors, but I think there should
be more annotated concepts.
Could you please try to annotate this document and compare results? I am
sure you will be able to find what I did wrong.

This is exactly the way, I would do it, too.

Re: Annotating using DBPedia ontology
Posted by Walter Kasper <wk...@apache.org>.
Hi,
We fixed the problem with unresolved relative URL from HTML documents.
In the case of your Wikipedia page it came from an embedded rel-license
microformat. If you are interested only in text extraction you can also
just disable the RDFa and Microformat extractors in the configuration
for the html extraction.
We tested also Word documents with your test sentence. Everything worked
fine for us. Did you use the correct mime type? The correct ones for
Word documents are:
doc-Format (<= Word-2003): application/vnd.ms-word
docx-Format (Word-2007):
application/vnd.openxmlformats-officedocument.wordprocessingml
Best regards,
Walter

Re: Annotating using DBPedia ontology
Posted by srecko joksimovic <sr...@gmail.com>.
Hi Walter,
Word document is nothing special, just one line of text:
"John Smith works for the Apple Inc. in Cupertino, California."
Rupert suggested this sentence in order to test text annotation. As I now
result after annotating this string, I thought to create Word document with
same content for test purposes.
The error with your HTML page apparently arises from a bug in resolving
relative URLs in one of the HTML extractors. We will fix that.
Does it means that I can't annotate HTML page at this moment, or that
depends on page to page basis?
Best,
Srecko

Re: Annotating using DBPedia ontology
Posted by Walter Kasper <wk...@apache.org>.
Hi Srecko,
I don't know what the problem with your Word document could have been.
Could you send it to me for testing?
The error with your HTML page apparently arises from a bug in resolving
relative URLs in one of the HTML extractors. We will fix that.
Best regards,
Walter

Thank you Rupert!
It is probably something that I missed.

Hi Srecko
I seams that both cases are related to the Metaxa Engine. My knowledge abut
the libs used by this engine to extract the textual content is very limited.
So I might not be the right person to look into that.
In the first Example I think Metaxa was not able to extract the text from
the word document because the only plainTextContent triple noted is
<j.0:plainTextContent>Microsoft Word-Dokument
srecko</j.0:plainTextContent>
The second example looks like an issue within the RDF metadata generation
in Aperture.
I sent this replay also directly to Walter Kasper. He is the one who
contributed this engine and should be able to provide a more information.

Re: Annotating using DBPedia ontology
Posted by Rupert Westenthaler <ru...@gmail.com>.
Hi Srecko
I seams that both cases are related to the Metaxa Engine. My knowledge abut the libs used by this engine to extract the textual content is very limited. So I might not be the right person to look into that.
In the first Example I think Metaxa was not able to extract the text from the word document because the only plainTextContent triple noted is
<j.0:plainTextContent>Microsoft Word-Dokument
srecko</j.0:plainTextContent>
The second example looks like an issue within the RDF metadata generation in Aperture.
I sent this replay also directly to Walter Kasper. He is the one who contributed this engine and should be able to provide a more information.

Rupert

Hi Rupert,
I have another question, and I will finish soon.
I tried to annotate pdf document, and I didn't get result I expected. Then
I put string you sent to me
"John Smith works for the Apple Inc. in Cupertino, California."
in MS Word document, and this is the result I got:

Hi Srecko
I think the last time I directly used this API is about 3-4 years ago, but after a look at the http client tutorial [1] I think the reason for your problem is that you do not execute the GetMethod.
Based on this tutorial the code should look like
// Create an instance of HttpClient.
HttpClient client = new HttpClient();
GetMethod get = new GetMethod(url);
try {
// Execute the method.
int statusCode = client.executeMethod(get);
if (statusCode != HttpStatus.SC_OK) {
//handle the error
}
InputStream t_is = get.getResponseBodyAsStream();
//read the data of the stream
}
In addition you should not use a Reader if you want to read byte oriented data from the input stream.
hope this helps
best

RE: Annotating using DBPedia ontology
Posted by Srecko Joksimovic <sr...@gmail.com>.
That's it. Thank you!
I have already configured KeywordLinkingEngine when I used my own ontology.
I think I'm familiar with that and I will try that option too.
In meanwhile I found another interesting problem. I tried to annotate
document and web page. With web page, I tried
IOUtils.write(byte[], out) and I had to convert URL to byte[]:
public static byte[] GetBytesFromURL(String _url) throws IOException
{
GetMethod get = new GetMethod(_url);
InputStream t_is = get.getResponseBodyAsStream();
byte[] buffer = new byte[1024];
int count = -1;
Reader t_url_reader = new BufferedReader(new
InputStreamReader(t_is));
byte[] t_bytes = IOUtils.toByteArray(t_url_reader, "UTF-8");
return t_bytes;
}
But, the problem is that I'm getting null for InputStream.
Any ideas?
Best,
Srecko

This are exactly the 5 engines that are expected to run with the default
configuration.
Based on this the Stanbol Enhnacer should just work fine.
After looking at the the text you enhanced I noticed however that is does
not mention
any named entities such as Persons, Organizations and Places. So I checked
it with
my local Stanbol version and was also not any detected entities.
So to check if Stanbol works as expected you should try to use an other text
the
mentions some Named Entities such as
"John Smith works for the Apple Inc. in Cupertino, California."
If you want to search also for entities like "Bank", "Blog", "Consumer",
"Telephone" .
you need to also configure a KeywordLinkingEngine for dbpedia. Part B or [3]
provides
more information on how to do that.
But let me mention that the KeywordLinkingEngine is more useful if used in
combination
with an own domain specific thesaurus rather than a global data set like
dbpedia. When
used with dbpedia you will also get a lot of false positives.

Hi Rupert,
When I load localhost:8080/engines it says this:
There are currently 5 active engines.
org.apache.stanbol.enhancer.engines.metaxa.MetaxaEngine
org.apache.stanbol.enhancer.engines.langid.LangIdEnhancementEngine

Maybe this could tell you something?

Hi Srecko
I googled for this exception and 90%+ of all pages had to do with Firewall
configurations on Windows machines.
The best description I found was on
http://weblogs.java.net/blog/binod/archive/2006/12/glassfish_and_w.html
About the enhancement result you posted: This is what the result looks like
if only the Metaxa and the LangId Engine are active. So I assume that the
other engines where not activated correctly. Maybe because of the
IOException
Can you please check if you use a Firewall that could cause this? Are you
running Stanbol on Windos?

Re: Annotating using DBPedia ontology

Hi Srecko
I googled for this exception and 90%+ of all pages had to do with Firewall configurations on Windows machines.
The best description I found was on http://weblogs.java.net/blog/binod/archive/2006/12/glassfish_and_w.html
About the enhancement result you posted: This is what the result looks like if only the Metaxa and the LangId Engine are active. So I assume that the other engines where not activated correctly. Maybe because of the IOException
Can you please check if you use a Firewall that could cause this? Are you running Stanbol on Windos?

No I would not propose you to upload the dbpedia dataset by using POST to
the entityhub. This is fine for small and medium sized datasets, but will
not work for dbpedia.
Stanbol comes already with a small sample set of DBPedia. This is also used
for enhancing documents with the default configuration.
This sample dataset contains the 43k DBPedia.org entities with the most
incoming links including some often used properties includinglabels in about
10 languages, the english comments, types, redirects stored as rdf:seeAlso,
lat/long, populations, birth/death dates, home pages, and category
assignments stored in dc-terms:subject.
You can easily upgrade this index to a bigger version by downloading the
dbpedia.solrindex.zip file form [1] and copying it into the /sling/datafiles
folder within the directory where your Stanbol server is running. After some
minutes (the time your computer needs to extract a file with ~3GByte) the
bigger index will replace the sample set included in the launcher.
If you need some additional fields, languages . you can also create your own
index by using the indexing tool for dbpedia [2]. See the README.md file for
instructions.
