  1. 1. Context Adaptive Service Framework(A Proposed Intelligent Agent and Knowledge Based Smartphone Application and Web Service Framework) John A. Yanosy Jr. jyanosyjr@gmail.comMarch 2012 Copyright (c) John A. Yanosy Jr. All 1 rights reserved.

  3. 3. Limitations of Current Smartphone And Web Services Ecosystem• User Cognitive Complexity: Smartphone Applications and Web Services Increase Opportunities while Increasing User Cognitive Complexity• Static Smartphone Framework: Current Smartphone application environments are static in nature and do not enable real time dynamic selection of applications and services to suit the specific user situational context. Only applications previously loaded are available for real time dynamic use.• Complex Application Discovery: User’s ability to successfully discover and select smartphone applications that are most relevant to their desires is becoming more complex due to the rapidly increasing numbers and types of applications offered• No Adaptation to User Context: The only context adaptation is for location based services for discovery on maps using current location. There is no other user context information used to adapt services.• Application Binding to Specific Web Service/Content Provider: Smartphone applications are typically bound to one or a very small set of Web Services and Providers.March 2012 Copyright (c) John A.

  5. 5. Context Adaptive Desired Characteristics and Enabling Technologies• Able to achieve user perceived adaptive behaviors through use of collaborative intelligent agent framework and knowledge of current and past context adaptations• Represent and reason about user preferences, situational contexts, past decisions and their outcome• Represent and reason about knowledge of services in a continuously expanding services ecosystem• Expanding set of Specialized Collaborative Network of Intelligent agents that learn about user situational context for service selection action decisions, their outcomes, and adjust their knowledge and beliefs to guide future decisions in similar situationsMarch 2012 Copyright (c) John A.

  6. 6. Context Knowledge and Adaptation• Situational Context and Different Perspectives: different people viewing the same situation can have different perspectives about what is important and which attributes to focus on.• Context Knowledge Representation and Reasoning: How can context knowledge be represented in a computer system and how is machine reasoning enabled?• Context Structure: Is there a structure or hierarchical context for different Smartphone user situations, where a particular context may be part of a larger context? Can you list different general context situations?• Separate of Knowledge and Decisions: what are the characteristics of an overarching framework that utilizes expanding knowledge of user situational contexts and available services while taking decision action or task decisions by an intelligent reasoning machine agent.• Knowledge Based Reasoning Logic and Intelligent Agents: What is the relationship between reasoning using knowledge inference using ontologies and the kind of reasoning an intelligent would make for decisions?• User Context Dynamics: Is it beneficial for the user to provide the system clues as to the current situational context? Is it desirable for the user to be able to have multiple contexts simultaneously? How should the system use the context clues from the user, the clues form the environment, from the personal profiles, from historical decisions?• System Adaptation: Is it useful think of the scope of system adaptation to user context, primarily oriented to service adaptation? What other system adaptations are related to user context? Should these desired adaptations be part of the user context knowledge model?• Smartphone Users: Do Smartphone users present unique context situations that do not occur in fixed location environments? What are some of these unique context situations? Add them to the previous list and context taxonomy for users.• Conflicts: When user preference are stored in a system, and user context clue given at system interaction time, how should the system resolve the conflicts between user stored preferences and learned decisions. Should the user be able to set context priorities, or should the system always give preference to instantaneous clues and override preferences. What if one or more people are involved in communications or other shared activity across the system, are there opportunities for translation adaptation when their different context perceptions and preferences are in conflict?March 2012 Copyright (c) John A.
