Integrating Wordnet with Natural Language Processing (NLP)
about 2 months ago - No comments
I’ve been working to get a release of my NLP Engine out the door but wanted to boost the built in dictionary / thesaurus before release. So this weekend I integrated Wordnet into the engine. Wordnet is available in RDF as a series of triples. As well as all the word definitions grouped into synonym More >
A Semantic Web ontology / triple Store built on MongoDB
about 1 year ago - 3 comments
In a previous blog post I discussed building a Semantic Triple Store using SQL Server. That approach works fine but I’m struck by how many joins are needed to get any results from the data and as I look to storing much larger ontologies containing billions of triples there are many potential scalability issues with More >
Hybrid Ontology + Relational Store with SQL Server
about 1 year ago - No comments
There are many references in the literature to exposing existing SQL data sources as RDF. This is certainly one way to integrate existing databases with semantic reasoning tools but it clearly requires a lot more storage and processing than simply keeping the data in SQL and querying over it directly. So recently I began some More >
An ontology triple (quad) store for RDF/OWL using Entity Framework 4
about 1 year ago - 3 comments
This weeks side-project was the creation of an ontology store using Entity Framework 4. An ontology store stores axioms consisting of Subject, Predicate, Object which are usually serialized as RDF, OWL, N3, … Whereas there’s lots of details about these serialization formats, the actual mechanics of how to store and manipulate them was somewhat harder More >
Applying the Semantic Web to Home Automation
about 1 year ago - No comments
Recently I’ve been considering how the Semantic Web will impact home automation. Technologies like the Web Ontology Language (OWL) and RDF allow for the construction of complex ontologies that define what things are, and how they relate. Using these ontologies automated reasoning can be applied to generate new facts or to prove or disprove assertions. More >
