1. Knowbot Information Service information science> KIS Also known as netaddress. The Knowbot Information Service KIS provides a uniform user interface to a variety of remote directory services such as whois, finger, X. 500, MCIMail. By submitting a single query to KIS, a user can search a set of remote white pages services and see the results of the search in a uniform format. There are several interfaces to the KIS service including electronic mail and telnet. Another KIS interface imitates the Berkeley whois command. KIS consists of two distinct types of modules which interact with each other typically across a network to provide the service. One module is a user agent module that runs on the KIS mail host machine. The second module is a remote server module possibly on a different machine that interrogates various database services across the network and provides the results to the user agent module in a uniform fashion. Interactions between the two modules can be via messages between Knowbots or by actual movement of Knowbots. There are electronic mail interfaces for KIS at the hosts cnri. reston. va. us and sol. bucknell. edu. Send a message containing just the word "man" to reston. va. us> or bucknell. edu>. Telnet: info. cnri. reston. va. us port 185. knowledge intelligence, information science> The objects, concepts and relationships that are assumed to exist in some area of interest. A collection of knowledge, represented using some knowledge representation language is known as a knowledge base and a program for extending and/or querying a knowledge base is a knowledge-based system. Knowledge differs from data or information in that new knowledge may be created from existing knowledge using logical inference. If information is data plus meaning then knowledge is information plus processing. A common form of knowledge, e. g. in a Prolog program, is a collection of facts and rules about some subject. For example, a knowledge base about a family might contain the facts that John is Davids son and Tom is Johns son and the rule that the son of someones son is their grandson. From this knowledge it could infer the new fact that Tom is Davids grandson. See also Knowledge Level.
