Presentation Transcript

  1. Context and Intent In Call Processing Tom Gray, Ramiro Liscano, Barry Wellman, Anabel Quan Haase, T. Radhakrishnan, Yongseok Choi

  2. Technological Change • Technological change now facing vendors of enterprise PBXs • Development of IP and wireless technologies for this market is apace • Large investment • However sales are not as hoped

  3. Assumption Change • Connections are made between devices • Devices are fixed in location • User identity is their device directory number • Device functions to a single user’s preferences • Busy is a device state

  4. How & Why People Communicate • Thomas J. Allen’s networks • networks of recognized competence • success correlated directly with amount of informal interaction • negative correlation - literature consultation and success • informal - new & tacit knowledge • communication and knowledge management are directly key to success

  5. Current Tools • Babble (IBM Erickson, Kellogg, Bradner) • social translucence - social affordances • visibility & higher performance • online, status, involvement with others • Hillier • architecture • predictive model of interaction from visibility • Both augment rather than recreate reality

  6. Features - Proactive Availability • Engender informal interaction by increasing casual visibility • voice mail - asynchronous | telephone - synchronous • Availability - willingness to talk • filters to allow visibility but to protect from unwanted interactions • multiple locations with multiple expectations of proper operation • visible clues from Hillier, Buxton … • organizational norms • stability

  7. Role As Relationship

  8. New Feature Types • Two new feature types • reactive (CoC) and proactive (PoA) • CoC • similar to current feature set but keyed to user current activity and role within organization • PoA • detect and analyze current user state and project availability for discussion

  9. Call Processing & Presence • Presence & Availability • relation to PoA & possible interactions • availability determined by state of call processing features (DND example) • presence is really hypothetical call processing • presence and call processing are specializations of a higher level concept

  10. Context & Intent • Context • ‘any information that can characterize the situation of an entity. An entity is a person, place or object that is relevant to the interaction between a user and an application including the user and applications themselves’ • similarity to role • Context can indicate Intent (purpose) and therefore proper call handling • c.f. Hillier, Babble, Buxton etc • who, what, when, where => why

  11. Tri-partite Architecture

  12. Context-Aware Call Processing

  13. FI and Context Rules • Filtering & Avoidance • Resolution emphasized over detection • Sociological resolution (generic rules) • Rules • most specific • newest • random • absolute • contextual background - importance and interruptability

  14. Current & Future Work • Policy Languages • human-aware filtering • Context and User Activity Sensing • Test and Development System • Native Call Processing Policy Engine • Add Hoc Distributed Meeting Tools

  15. Conclusions • Current feature set does not full exploit possibilities of IP telephony • New areas of feature operation becoming available • informal and ad hoc group services • Personalization is about group behavior • Polices offer way forward • FI - filtering and resolution
