Haptic technology and expressiveness of the bow (haptic device) held by the artist. This can be done with physical modeling synthesis. Designers and modellers may use high-degree-of-freedom input devices that give touch feedback relating to the "surface" they are sculpting or creating, allowing faster and more natural workflow than traditional methods. Artists working with haptic technology such as vibrotactile effectors are Christa Sommerer, Laurent Mignonneau, and Stahl Stenslie. Digital drawing or handwriting tasks can be enhanced and produce better outputs with a more realistic feedback which is designed to enable artists or writers to feel as if they are drawing or writing
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
