HI everybody,
I want to develop a java system which indexes a set of documents represented
by an ontology. Is this could be done with lucene.
I yes what are the plugins which I have to use.
Thank you very much.
Amir.

About semantic indexing, we have an API that "disambiguates"
documents--it determines part of speech, compounds, senses, dependencies
between words, named entities--and returns xml/json info that looks like
the following for example if you disambiguate [semantic indexing] :
| <docs len="2" num="1">
<doc len="2">
<sensesInfo>
<sense csk="semantic/C2" fs="semantic/J1" fsk="semantic/J1">
<desc>of or relating to the study of meaning and changes of
meaning.</desc>
<extRef>
<dm>wikipedia</dm>
<ref>29107</ref>
</extRef>
<extRef>
<dm>wikipedia</dm>
<ref>397608</ref>
</extRef>
</sense>
<sense csk="index/C1" fs="indexing/N1" fsk="indexing/N1">
<desc>the act of classifying and providing an index in order to make
items easier to retrieve.</desc>
</sense>
</sensesInfo>
[...]

You can then retrieve properties, categories of the disambiguated
senses, climb up or down those hierarchies, and have a real semantic
index. Disambiguated senses also have information connecting to
wikipedia article ids. You could also map those to any existing ontology.
