Abstract: A reputation management system assigns reputation scores to various types of entities including, but not limited to people, products, advertisers and merchants. A reputation function is based on a directed graph including the reviewers and the reviews. The nodes in the graph represent the reviewers and the reviews and the links in the graph represent the ratings. Ratings may be negative in nature so the links which may include negative values which must be accounted for in the reputation function. The reputation function is iteratively solved until a convergence condition is met. Prior to convergence, when a stability condition is met nodes with negative reputations are removed from the reputation function.

Abstract: A Web site development tool such as WikiWiki allows a value to be referenced on a page other than the page on which the value is defined. The reference syntax may indicate the name of the page on which the value is defined and the value name, such as with a dot notation: <page name>.<value name>. Translation of Wiki source to HTML is executed in a manner which enables changes to the value in the value-defining page to be reflected in the value referencing page, i.e., the value reference is dynamic. Further, use of a symbolic name to represent a value is supported. Performance of calculations with a value and page aliasing are also supported.
