Haptic technology manufacturers such Nokia, LG and Motorola have included different types of haptic technologies in their devices; in most cases, this takes the form of vibration response to touch. Alpine Electronics uses a haptic feedback technology named "PulseTouch" on many of their touch-screen car navigation and stereo units. The Nexus One features haptic feedback, according to their specifications. Samsung first launched a phone with haptics in 2007. Surface haptics refers to the production of variable forces on a user's finger as it interacts with a surface, such as a touchscreen. Tanvas uses an electrostatic technology to control the in-plane forces experienced
Word-sense induction shown to achieve the state-of-the-art performance in standard evaluation tasks. Word-sense induction In computational linguistics, word-sense induction (WSI) or discrimination is an open problem of natural language processing, which concerns the automatic identification of the senses of a word (i.e. meanings). Given that the output of word-sense induction is a set of senses for the target word (sense inventory), this task is strictly related to that of word-sense disambiguation (WSD), which relies on a predefined sense inventory and aims to solve the ambiguity of words in context. The output of a word-sense induction algorithm is a clustering of contexts in
