Copyright (c) Scientio LLC 2004-6 all rights reserved. This schema defines the Metarule language, which is a mechanism for describing fuzy logic rules and fuzzy arithmetic based algebraic expressions. Root node A single if..then rule Placeholder, signifies start of rule An identifier used in editing and viewing of the rule set. these should be globally unique. logical 'and' logical 'or' logical 'not' evaluates a numeric, categorical, textual or other comparison. an externally supplied data value used in a rule. a fuzzy set A short and discrete textual state that an input or output can contain. indicates that the conditions for the rule to fire will be unconditionally met. fuzzy version of numeric power operator. indicates the contained opeators return a numeric value. Fuzzy arithmetic addition. Fuzzy arithmetic subtraction. Fuzzy arithmetic multiplication. Fuzzy arithmetic division. Fuzzy arithmetic unary sign inversion represents an output value created by this ruleset. A singleton numeric constant. separator. In the data dictionary section indicates the input definitions. In the data dictionary section indicates the output definitions. An individual input definition. an individual output definition. Defines the input or output as posessing categories. Defines the input or output as numeric. Introduces a set definition. Lower bound of a set. Upper bound of a set. Placeholder at start of rule. Placeholder between conditional and output section of the rule. Documentation only - the date the ruleset was created. Documentation only - the source of the data if created from a data set via data mining. Documentation only - The editor or data mining system that created the rule set. Documentation only - The number of examples used to generate the rule set if crated by data mining. Fuzzy arithmetic sum function. Sigmiod squashing function used in simulations of neural nets. The degree of certainty attached to a rule. Range 0-1 A number specifying the order of execution of outputs. Lower numbers are executed first. The middle value of a triangular fuzzy set. no longer used. no longer used. no longer used. Fuzzy numeric comparison operator. Fuzzy numeric comparison operator. Fuzzy numeric comparison operator. Enables the composition of a fuzzy number from several (2-4) singletons. Typically used with constants. predefined category used with presence inputs and outputs. predefined category used with presence inputs and outputs. XPath statement locating the data for inputs or outputs relative to the selectionpattern. Cost data Defines an input or output as 'presence' i.e. responding to or predicting the presence or absence of a node. Reserved for future expansion. Reserved for future expansion.

Should not appear in a working ruleset. for trapezoidal fuzzy sets indicates the lower middle bound. for trapezoidal fuzzy sets indicates the upper middle bound. collection of namespaces needed to locate data in the data source. An individual namespace. The uri of a namespace the prefix of a namespace. Indicates that the value of the given input is updated by this output. Represents a single association found in the input data. Matches a regular expression contained in a string constant to the textual value on the other side of the 'is' operator. A string constant a collection of numeric constants a collection of string constants. a single numeric constant definition. a single string constant definition. the name of the constant used within rules. The value of the constant. The text of a string constant. Used as a placeholder during editing. Should not appear in a working ruleset. Fuzzy arithmetic product operator.
