Abstract
Dr. Christian Hempelmann introduces an implementation of ontological semantics (OntoSem), a theory for deep-meaning representation, for a specific, complex NLP application: the meaning-based Internet search engine hakia. Dr. Hempelmann will provide a general overview of how OntoSem is used in hakia's proprietary QDEX technology, as well as give an in-depth account of key issues in Web search.
|
Furthermore, the presentation will provide the distinction between semantic content and purportedly semantic formalisms. Meaning for Web search requires complex description for automatic generation and cannot be extracted from surface text with statistical methods nor with generic, opportunistic, pseudo-semantic resources, such as WordNet, with its low-resolution synsets and unstructured annotations that are unavailable for computation.
Overall, the presentation will address the questions:
- What is Ontological Semantics?
- How is it used to power the Internet search engine hakia?
- What are the different uses of the term "semantics" in the search industry today?
