Natural Language Understanding requires establishing the “meaning” of what is read. For SIRA, “meaning” is the mapping between an “experience” (e.g. reading something) and a “World View” (represented by Ontology). In this way, experiences are “understood” in terms of what is already known (the World View). SIRA’s World View automatically grows with use. At any time, knowledge can be exported and shared. Third party domain Knowledge can also be uploaded. As SIRA’s Ontology improves, overall accuracy and performance improves.
