Selected Talks

Practical Roles of Semantics, keynote speech at International Workshop on Semantic Computing 2008, Inchoen, Korea / invited talk at Samsung Electronics, KT, Hyundai-Kia Motors, 2007~2008.

We are yet to witness the realization of the Semantic Web, even after years of research and promotions by various institutions including the W3C. Some critics are quick to sign off semantic technology as just another rhetoric for promoting AI research. However, recently, we are seeing more and more practical applications that can be categorized into semantic applications. An interesting observation is that most of these cases rely less on inference but more on extensions of meta data and standardization. With careful design and incremental extensions, it is possible to achieve practical benefits from semantic technology. In this talk, we introduce our strategy to adopting semantics in a practical way. Also presented are a few of our research efforts in this direction; semantic product information management, concept-based search, and context-aware personalization.

Semantic Technology Roadmap, at Semantic Technology Conference 2008, San Jose, USA.

With the recent market saturation and increasing competition in the telco industry, Korea Telecom (KT), which is one of the largest companies in Korea, is making an all-out effort to discover new growth momentum for the future. Conveniently named Telco 2.0, the theme for KT's efforts is to transform itself into a customer-centric and highly innovative company focusing on the five new business areas of contents, solution, cultural complex, knowledge consulting, and computing. The importance of the IT architecture (ITA) in realizing this vision cannot be overstated. The ITA for the future must support effective real-world representation, deal with various levels of heterogeneity, and provide intelligent processing over enriched information. We will present KT's semantic technology roadmap and show how we expect semantic technology to address these areas. We will also introduce KT's semantic search engine STARS developed as part of these efforts.
