Abstract

A computer-based method for assisting a user in making decisions in the process of completing a task is shown and described. The method of the system includes providing a set of questions for completing the task, asking the user a first question from the set, and providing a choice of answers to the first question. The system also provides advice from its knowledge base for deciding which of the answers to the first question to select. The choice of answer, however, remains under the control of the user, who can exercise judgment based on the user'"'"'s expertise and the advice provided by the decision management system. The method continues by asking following questions, with the following questions, answers and advice influenced by the user'"'"'s previous answers. Throughout the decision-making process, the user retains control of the answers if so desired, with the system providing advice from its knowledge base. The system is particularly suited for document assembly in allowing a professional to determine what provisions are suitable for a document to be built from information and judgments provided by the professional and the knowledge base of the system. The system also includes an authoring program for preparing applications that run on the system. Using an intuitive program block approach of the authoring program, an author can construct an application by placing questions, answer choices, advice and textual and logical provisions in named program blocks. The author then assembles and arranges these blocks to build a desired application program.

Claims

1. A computer-assisted decision management system comprising:

a computer;

an authoring tool stored in a computer for creating applications, the authoring tool including an editor for creating a set of question procedures for asking questions of a user, one or more of the procedures containing a reference to a referenced procedure and also creating a referenced procedure for a question procedure, the referenced procedure generating content literally different from but based on an analysis of one or more previous answers entered by a user in response to a question, the referenced procedure providing the content to the question procedure for use in generating a question;

applications stored in a computer for generating questions and answer choices from question and answer procedures created by the authoring tool; and

an execution program being executed on the computer for executing an application, the execution program asking questions of the user from the application, providing answer choices to the user from the application, and determining following questions and answer choices from the application based in part on the user'"'"'s answer to a previous question, the execution program assembling a document according to answers chosen by the user.

2. The system of claim 1 wherein a question procedure contains references to multiple referenced procedures.

3. The method of claim 1 wherein a referenced procedure contains a reference to another referenced procedure.

4. The method of claim 1 wherein a referenced procedure includes a conditional statement that chooses a result from a group of possible results based on one or more previous answers entered by a user.

5. The system of claim 1 wherein at least one of the created procedure is a referenced procedures and at least one of the created answer procedures contains a reference to a referenced procedure, the referenced procedure generating content literally different from but based on an analysis of one or more previous answers entered by a user in response to a question, the referenced procedure providing the content to the answer procedure for use in generating an answer choice.

6. The system of claim 1 wherein the editor creates advice procedures for the application for advising a user with respect to a question, one or more of the advice procedures containing a reference to a referenced procedure that generates content literally different from but based on an analysis of one or more previous answers entered by a user in response to a question, the referenced procedure providing the content to the advice procedure for use in generating advice.

7. The system of claim 1 wherein the reference in the question procedure is a call to the referenced procedure.

8. The method of claim 1 wherein the decision management system is a document assembly system.

9. A computer-assisted decision management system, comprising:

an editor stored on a computer for creating a set of question procedures for asking questions of a user, one or more of the procedures containing a reference to a referenced procedure and also creating a referenced procedure for a question procedure, the referenced procedure generating content literally different from but based on an analysis of one or more previous answers entered by a user in response to a question, the referenced procedure providing the content to the question procedure for use in generating a question; and

an application being executed on a computer for executing a created question procedure that contains a reference to a referenced procedure therein,

the application also generating answers to questions produced by the question procedures and assembling a document according to answers chosen by the user.

10. A computer-implemented method of creating a document, the method comprising:

creating a set of question procedures for asking questions of a user, one or more of the procedures containing a reference to a referenced procedure and also creating a referenced procedure for a question procedure, the referenced procedure generating content literally different from but based on an analysis of one or more previous answers entered by a user in response to a question, the referenced procedure providing the content to the question procedure for use in generating a question;

generating questions from the set of created question procedures;

generating answer choices for the questions for a user; and

assembling the document according to answers chosen by the user in response to the questions.
