bandwidth reduction

• Bin Wang– Quality of Service, survivability, human participation, traffic

isolation, trace back

Relevant Group Expertise

• Content extraction and secure transmission– Feature extraction, compression, Image analysis, motion pattern

analysis, semi structured text analysis, web security, transmission, distributed multimedia information retrieval, Intelligent agents, and Quality of Service

• Knowledge Assisted Rapid Knowledge Fusion– Semantic nets, semi-structured text analysis, image analysis,

motion pattern analysis

• Human Computer Interaction– Multimodal multimedia interfaces, domain specific visualization,

multimedia triggers, virtual multimedia agents, intelligent agents, fault tolerance, adaptability and survivability

Potential Collaborative Effort

• Knowledge assisted progressive Image analysis

• Immunity based web transmissions

• Immunity based multi agent systems

• Integration of semi-structured text and image analysis for multimodal knowledge refinement

Goal

• Web based active and reliable knowledge extraction and fusion

• Knowledge management should mimic human capability

• Seamless immersible integration

• Exceeding capacity, efficiency, accuracy with human in loop

Dual Capabilities

• WWW based content analysis– news and media clip analysis– Real time streaming news analysis

• Reconnaissance Dynamic Scene Analysis– real time pattern movement and formations– real time analysis of disasters (natural hazard, war effect etc.)– real time target identification

Taxonomy

• Content extraction– web based search, distributed and parallel database search– text, image, audio, audiovisual analysis– feature extraction and matching

• Knowledge fusion– knowledge representation (ontologies, for layered abstraction)– dialog protocols (resolve ambiguity and incompleteness on need

to know basis)– knowledge validation – consistency checking and human based verification– knowledge transformation (layered abstraction, filters to take

care of privilages on need to know basis)– reactivity (provactive, predictive and dissemination)

Taxonomy (continued)

• Secure infrastructure– Quality of Service– reliability, availability, heterogeneity,– security (reactive), immunity– fault tolerance and adaptability– distributed access and storage over the web– local access and storage– query generation

• Human computer interaction– decision support– collaboration– immersion– visualization
