An embodiment of the present invention is a method for generating an object-oriented model from a vocabulary, the vocabulary comprising terms and sentential forms, each of the terms representing a concept, each of the sentential forms representing a fact type and including at least one placeholder, the placeholder being specified by a term. For each of the terms in the vocabulary, a class is created. Each instance of the created class represents a fact that a thing is classified to be an instance of the concept represented by the corresponding term. For each sentential form in the vocabulary, a class is created. Each instance of the created class represents a fact that is an instance of the fact type represented by the corresponding sentential form.

What is claimed is: 1. A method for generating an object-oriented model from a vocabulary, the method comprising the operations of: (a) receiving the vocabulary comprising terms and sentential forms, each of the terms comprising a word or phrase representing a concept, each of the sentential forms

What is claimed is: 1. A method for generating an object-oriented model from a vocabulary, the method comprising the operations of: (a) receiving the vocabulary comprising terms and sentential forms, each of the terms comprising a word or phrase representing a concept, each of the sentential forms comprising a prepositional statement representing a fact type and including at least one placeholder, the placeholder being specified by a term; (b) automatically creating a first class for each of the terms in the vocabulary; (c) making a classification superclass to be a superclass for each of the first classes, wherein the classification superclass is a subclass of a fact superclass, wherein the fact superclass is a superclass whose instances are facts, such that each instance of the first class represents a fact that a thing is classified to be an instance of the concept represented by the corresponding term rather than representing an instance of the concept, and wherein the classification superclass is a superclass whose instances are classifications; (d) automatically creating a second class for each sentential form in the vocabulary; (e) making the fact superclass to be a superclass for each of the second classes, wherein the fact superclass is a superclass whose instances are facts, such that each instance of the second class represents a fact that is an instance of the fact type represented by the corresponding sentential form; and wherein acts (a)-(e) are performed so as to limit the granularity of encapsulation of information in each of the first classes and the second classes to no larger than the representation of a single fact. 2. The method of claim 1 further comprising: (f) creating a package; and, (g) making each of the classes created in operations (b) and (d) to be a member of the package. 3. The method of claim 1 wherein operation (b) comprises: associating the first class with a name, the name including, as at least a portion of the name, the term for which the first class is created. 4. The method of claim 1 wherein operation (b) comprises: creating an attribute in the first class, the value of the attribute in an instance of the first class representing a thing being classified. 5.
