Modality

From Academic Kids

  • In language, modality is the subject concerning so-called "modal verbs" like can, must, and should, that are customarily used to modify the meaning of other verbs (which in turn tend to take the infinitive). Modal verbs express possibility (and impossibility, necessity, contingency, etc.), permissibility (and obligation, proscription, etc.), probability (and improbability, etc.). See grammatical mood. Linguistic modality can also refer to the type of communication, whether vocal, signed, or written.
  • In computer science and particularly computer vision, modality refers to the type of input. That is, black-and-white, color and infrared are three different modalities for the acquisition of an image.
  • In advance fee fraud (Nigerian 419 Scams), the term modality is used to describe the method of funds transfer. Often used in as a key word in scam baiting
