Re: [IKS] About semantic search

Hi Olivier, on a side note I will soon commit the code started in 
Salzburg to "unify" the vocabulary translator facility with the refactor 
engine so that it combines refactoring and (optionally) reasoning, with 
selectable recipes/vocabularies.

thanks

alessandro

Hi all

Mind that you can also use LDPath for translating in-between schemata's. You can also use to follow inverse and transitive properties as well as longer paths. 

You can play around with the example provided by the RESTful interface documentation of the Entityhub. 

* [1] : Allows to execute LDPath statements on dbpedia
* [2]:  Gemet is a SKOS thesaurus. A search for "Nuclear" with an LDPath program like

skos:prefLabel;
skos:altLabel;
skos:hiddenLabel;
rdfs:label = (skos:prefLabel | skos:altLabel | skos:hiddenLabel);
skos:notation

skos:inScheme;

skos:broader = (skos:broader | ^skos:narrower);
skos:broaderTransitive = (skos:broader | ^skos:narrower)+;

skos:narrower = (^skos:broader | skos:narrower);
skos:narrowerTransitive = (^skos:broader | skos:narrower)+;

skos:related = (skos:related | skos:relatedMatch);
skos:relatedMatch;
skos:exactMatch = (skos:exactMatch)+;
skos:closeMatch = (skos:closeMatch | (skos:exactMatch)+);
skos:broaderMatch = (^skos:narrowMatch | skos:broaderMatch);
skos:narrowMatch = (skos:narrowMatch | ^skos:broaderMatch);

shows how LDPath can be used to perform SKOS reasoning. 

I consider the use of LDPath as an alternative for providing mapping functionality between rNews<->DBPedia

WDYT

This is precisely what I had in mind.

Ok, I got it.
We can associate to each rule set a different recipe.

In order to have independently configured instances of the same engine we might enable the SCR factory in the Refactor engine.

I meant two rules sets that can be configured to be used by two
independently configured instances of the same enhancer engine class /
factory.

Hi Olivier,
ok, we can write down the mappings rNews<->DBPedia and DBPedia<->schema.org

I didn't understand what you mean by " to have an independent implementation".

Thanks
