Haptic perception by use of his body". Gibson and others further emphasized what Weber had realized in 1851: the close link between haptic perception and body movement, and that haptic perception is active exploration. The concept of haptic perception is related to the concept of extended physiological proprioception, according to which when a tool such as a stick is used, perceptual experience is transparently transferred to the end of the tool. Haptic perception relies on the forces experienced during touch. This research allows the creation of "virtual", illusory haptic shapes with different perceived qualities, which has clear application in haptic technology. People
Word-sense disambiguation is that similar senses occur in similar contexts, and thus senses can be induced from text by clustering word occurrences using some measure of similarity of context, a task referred to as word sense induction or discrimination. Then, new occurrences of the word can be classified into the closest induced clusters/senses. Performance has been lower than for the other methods described above, but comparisons are difficult since senses induced must be mapped to a known dictionary of word senses. If a mapping to a set of dictionary senses is not desired, cluster-based evaluations (including measures of entropy and purity) can
