© Ramesh Jain Semantics Meaning Negotiation process: requires agreement among all involved participants Every User has their ‘personal ontology’ Personal ontology can not be matched with the system ontology in one step (one query) --- requires an emergent process.

© Ramesh Jain The Semantic Gulf Data is organized based on data characteristics. Efficiency and Scalability are primary User intentions and context are not considered. Query environment does not maintain the state of the user.

© Ramesh Jain Access: Impedance Mismatch Computers are millions of times faster than humans in arithmetic and logic. People are millions of times better than computers in perceptual and conceptual tasks. Any one year old can recognize objects! Current computing environments were designed for people to serve computers. Consider computers and humans part of a symbiotic system.

© Ramesh Jain Kalman Filtering Processing Model Data

© Ramesh Jain Basic Concept Model: Mathematical State and other relations Current State = F (Previous State, New Observations) Models states and transitions based on each source of data

© Ramesh Jain Unified Indexing Should allow indexing into all data and information sources Should be independent of a medium Should not use idiosyncrasy of a medium Video: time, frame number; Text: page, line;...

© Ramesh Jain Symbolic Kalman Filtering The Model is Hybrid – combination of symbolic and mathematical. Each Data Source is an independent observation source. Model is updated based on its current state and new observations. Essential for live and sensory data assimilation.

© Ramesh Jain Entities and Events Events are dynamic. Event Name Duration Location Attributes Data-streams Processes Adjacent States Related Links Entity Name Attributes Processes (Services) Objects and Entities are static.

© Ramesh Jain Modeling a Domain Event Graphs: Capture relationships among events and entities. Event Transitions: Conditions and probabilities of transitions.

© Ramesh Jain Experience: Direct Observation of or Participation in Events as a basis of knowledge

© Ramesh Jain Webster definitions: Events: something that happens Data: factual information (as measurements or statistics) used as a basis for reasoning, discussion, or calculation Experience: direct observation of or participation in events as a basis of knowledge Insight: the act or result of apprehending the inner nature of things or of seeing intuitively Knowledge: the fact or condition of knowing something with familiarity gained through experience or association Information: the communication or reception of knowledge or intelligence

© Ramesh Jain Objectives Experiential environments are the next major technology inflexion point. Unified indexing of assimilated data is essential to implement experience-centric, rather than current information-centric, systems. Semantics is ubiquitous and emerges with symbiotic interactions among a user and the system.
