Lexical knowledge bases

One of the major current requirements in real world natural language processing applications is the construction of suitably structured and sufficiently exhaustive computational lexicons or lexical knowledge bases (LKBs). However, this is an extremely difficult, time consuming and expensive task, especially if it is necessary to start from scratch. For this reason, in recent years, researchers have begun to examine the potential or already existing resources, such as machine readable dictionaries and text archives, to see whether it is possible to develop procedures that can capture different kinds of lexical information from them, representing it in a computationally tractable and reusable formal framework.
