For Example: Histograms Histograms. Knowledge Representation Knowledge representation is the presentation of knowledge to the user for visualization in terms of trees, tables, rules graphs, charts, matrices, etc. Logical representations, whose origins lie in the traditions of philo- sophical and mathematical logic, were proposed early as both semantic rep-resentations and as representations for commonsense knowledge, including knowledge about actions, abilities, goals, and causes. For example, imagine we have a 3 x 3 chess board with a knight in each corner and we want to know (Fig. Language Knowledge of a language including elements such as vocabulary, grammar, semantics, phonology and nuance. Mechanism for representation and manipulation of existing knowledge to create new solution. Historically the claim has often been phrased in terms of equivalence to logic. Different implementations, i.e. Example. Ease of Representation: The ease with which a problem can be solved depends upon knowledge representation scheme. As nearly all of AI research is done by programming computers, these representations often end up being some kind of character set in software. • To solve complex problems we need: 1. Semantic nets, for example, have been described in these terms (e.g., Scripts 29 Definition A script is a structured representation describing a stereotyped sequence of events in a particular context. Disclosure: qualifying a representation or warranty with information disclosed on a disclosure schedule. Many DLs are more expressive than propositional logic but less expressive than first-order logic.In contrast to the latter, the core reasoning problems for DLs are (usually) decidable, and efficient decision procedures have been designed and implemented for these problems. Data, when processed, becomes information, information when interpreted or evaluated becomes knowledge and understanding of the principles embodied with the knowledge … issues in knowledge representation Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

KNOWLEDGE REPRESENTATION & PREDICATE LOGIC Amey D.S.Kerkar, Asst.Professor, Computer Engineering Dept. There one has a relatively widely understood set of … At most, computation has been considered in relation to complexity issues. Maps are a good example of knowledge representations. Knowledge representation is the idea to make ones data smarter in a way that you are able to move some of the application logic out of it and make data.
