Commonsense Knowledge Base

Commonsense Knowledge Base

In artificial intelligence research, commonsense knowledge is the collection of facts and information that an ordinary person is expected to know. The commonsense knowledge problem is the ongoing project in the field of knowledge representation (a sub-field of artificial intelligence) to create a commonsense knowledge base: a database containing all the general knowledge that most people possess, represented in a way that it is available to artificial intelligence programs that use natural language or make inferences about the ordinary world. Such a database is a type of ontology of which the most general are called upper ontologies.

The problem is considered to be among the hardest in all of AI research because the breadth and detail of commonsense knowledge is enormous. Any task that requires commonsense knowledge is considered AI-complete: to be done as well as a human being does it, it requires the machine to appear as intelligent as a human being. These tasks include machine translation, object recognition, text mining and many others. To do these tasks perfectly, the machine simply has to know what the text is talking about or what objects it may be looking at, and this is impossible in general unless the machine is familiar with all the same concepts that an ordinary person is familiar with.

Information in a commonsense knowledge base may include, but is not limited to, the following:

  • An ontology of classes and individuals
  • Parts and materials of objects
  • Properties of objects (such as color and size)
  • Functions and uses of objects
  • Locations of objects and layouts of locations
  • Locations of actions and events
  • Durations of actions and events
  • Preconditions of actions and events
  • Effects (postconditions) of actions and events
  • Subjects and objects of actions
  • Behaviors of devices
  • Stereotypical situations or scripts
  • Human goals and needs
  • Emotions
  • Plans and strategies
  • Story themes
  • Contexts

Famous quotes containing the words knowledge and/or base:

    “Now all the knowledge and wisdom that is in creatures, whether angels or men, is nothing else but a participation of that one eternal, immutable and increated wisdom of God, or several signatures of that one archetypal seal, or like so many multiplied reflections of one and the same face, made in several glasses, whereof some are clearer, some obscurer, some standing nearer, some further off.”
    —Ralph J. Cudworth (1617–1688)

    “The desire of most parents is first and foremost to do what is best for their children. Every interview with a mother or father confirms this, every letter written by a parent breathes this deep-seated wish, “I hope I am doing the right thing for my child.” This is real and honest, and at the very base of parenthood.”
    —Irma Simonton Black (20th century)
