Reasons to Study Context

Motivation :


• We humans often exploit context when we communicate and take actions. Because we are context-aware beings, we are able to effectively convey ideas without needing to explicitly state background information during conversations.
  
• For example, when two people walk into the same room, one person tells the other person, ``Close the door, please''.
  
• Because they share a common context, there is no need for the first person to explicitly point out the door he intends to close.
• Context can also guide us to adapt behavior in changing environment conditions.
  
• For example, in a movie theater, when a movie starts to play, we usually try to avoid loud conversations; when driving on a highway, as traffic becomes heavier, we usually slow down in order to avoid hitting other cars.
  
  
• Because the notion of context effects the intelligent behavior of the humans, it is generally agreed that context-awareness should be simulated in computing systems to strengthen their capability to communicate, to behavior and to process information. Context has been studied in many different fields of computer science, including Artificial Intelligent, Information Retrieval, Nomadic Computing, Sensor Networks and Ubiquitous Computing . Although different fields of research have studied contexts with distinctive aims, they all recognize that context-awareness is the vehicle to the realization of intelligent computing systems.
  
  
  
• Hence, now realising the importance of Context, I would like to begin my discussion with an very interesting example of a small word "YET" in different Context.
