Natural Language and Semantic Technology: The Chasm & Some Bridges

Guest Speaker; Michael Niv, Senior NLP Scientist, Orbis Technologies, Inc.

The aim of this talk is to familiarize Semantic Technology practitioners with the relevance of their work to NLP and vice versa.

Natural Language Understanding (NLU) is one of the principal aims of Natural Language Processing (NLP).  The objective of NLU is to extract computer-usable meaning from natural language text.  We begin by contrasting natural language and computer/logical languages. This illustrates the magnitude of the chasm that NLP needs to bridge in order to deliver on the challenge of NLU.  We then survey several bridges over this chasm:

 * Techniques for extracting limited portions of the meaning (word
statistics, named entities, properties/relationships)

 * Reframing the task of NLU within the task of the broader IT system
that contains it, making it more tractable

 * Techniques for acquiring knowledge (including ontologies) to
improve breadth and depth of NLU

 

Spotlight Series; Building the Semantic Model, First RDF and RDFS

John Hebeler, Senior Associate, Booz Allen & Hamilton

Continuing our brief, spotlight talks we move into the foundation technologies of RDF and RDFS - the basic building blocks of the Semantic Web.  How do they support the model and what are their implications?  We take our current project back a step and in doing so reveal the power in simple modeling techniques.  This also sets the stage for future spotlight discussions on OWL and OWL 2

    Thats to John for his Spotlight on RDF, Michael Niv did an excellent job of conveying the vast complexities of NLP and how the are currently being addressed. Good exchange at the end.
