Smart Instant Messenger @ HKU

This project is to implement a smart instant messenger (SIM) that can help mobile users to perform context-aware person-to-person interactions and enable mobile users to instantaneously make use of devices present in a working space. Context information, such as room location, person identity, computing resources, personal profiles, schedule, etc., will be retrieved and inferred by a reasoning engine to provide correct decisions (smartness). A special feature of SIM is the support of application mobility, where an executing application, such as a music player, can be moved across nearby devices, but continue its execution (playing the same music). The implementation involves Java programming on PDA (or mobile phone with J2ME), client-server network programming on wireless LAN (802.11b, BlueTooth, or IrDA, etc.). (More...)

Communication between human and artificial agents
  • Agent communication languages, like ACL and KQML, have been a focus of attention in recent years. But they are far from reflecting the complexity of human communication.

  • Issues: representations of mental states, believes and intentions, sensory information, formal representations of actions and action ontologies, and the integration of context and situation information,
