Course Inventory Expert System

Revised April 14, 1999


What is the Course Inventory Expert System?

An "expert system" is a computer system that reproduces the decision-making process of an expert in a certain field of
knowledge. The Course Inventory Expert System is a logical representation of the decision rules for classifying undergraduate courses, which have been converted to a step-by-step process.

The Course Inventory Expert System utilizes a series of decision trees to guide users (i.e., institutional and Regents staff) through the decision-making process. The goal is to achieve consistent treatment of all undergraduate courses across the system based on existing decision rules and policies.

For institutional staff, this tool functions as an objective means for applying the decision rules while developing the Course
Inventory (CI) file submission. Following each step in the process reduces the possibility of any arbitrary or subjective interpretations in determining course subsidy assignments and, therefore, has the effect of creating an audit trail. Once the Course Inventory Expert System is in the production mode, Regents staff will be able to ensure the proper application of the decision rules across the system by conducting periodic reviews of the course data.

From the state perspective, the analysis of subsets of courses would detect weaknesses in reporting among institutional staff--a
possible indicator of training needs--and for identifying ambiguities or inequities in the decision rules. Furthermore, the dynamic
nature of academic programs and policy development naturally indicates the need to devise and implement enhancements or
revisions to the Course Inventory Expert System on a routine basis.

Using the CI Expert System

There are four stages in the Course Inventory Expert System. Each stage is designed to narrow the universe of courses under consideration. This "process of elimination" forms the basis for achieving consistent assignments of courses to subject codes and levels among institutions. Please note: While developing this system, the following issues were acknowledged as requiring further study:
  1. (1) processes external to the HEI system which are candidates for inclusion in the data collection efforts of the HEI system (e.g., transfer module courses and courses required for a technical degree), and
  2. (2) decision rules, guidelines, or policies which require further clarification in order to be applied consistently.

Stage One

In this stage, the system begins differentiating particular institution types and "classes" of courses. The first series of questions in Stage One are designed to focus on the type of institution and the institutional staff member; to eliminate certain "classes" of courses from further consideration; and to guide the user to other stages of the process for all other courses.

Example: A four-year institution representative progresses through the decision tree via a series of questions. When asked if a course is a Transfer Module course, the representative who follows the "Yes" path is prompted to go to Stage Three, thereby removing the possibility that the course could be subjected to inappropriate criteria. If the "No" path is selected, a message (triggered by clicking on the hyperlink in the "No" arrow) provides the criteria for confirming that the course does not function as a Transfer Module course. Similar "flags" appear for developmental education courses and for courses required for technical degree programs.

Notice that Stage One reduces the course universe into two types:

  1. courses identified as a technical degree program requirement in any category--Basic, Non-technical, or Technical--or as a technical elective within a technical degree program, and
  2. courses not identified as a requirement for a technical degree program. Courses of the first type are eligible only for General Studies or Technical level funding regardless of institution type--the focus of Stage Two. Those of the second type would be assigned to the General Studies level at technical colleges. Four-year university or a community college data reporters would subject these courses to the decision rules for determining General Studies or Baccalaureate level subsidy--described in Stages Three and Four.

Stage Two

In order to enter Stage Two, the data reporter determined in Stage One that the course is required for a Technical Degree program. Note that both the "Yes" and "No" arrows in Stage One are linked to confirmations of the relationship of a course to a Technical Degree program.

Once the data reporter arrives at Stage Two, the system reconfirms that the course was subjected to Stage One criteria. Stage Two further certifies that the course is a Technical Degree program requirement and guides the level assignment of these courses.

Stage Three

The data reporter accesses Stage Three through Stage One. This stage is designed to glean from the remaining universe of courses those in categories that are not unique to a particular field of study but rather to the type of course, to the curricular significance of the course, or to aspects of the course which define its level.

Stage Four

In reaching this stage, the course universe has been considerably reduced. Now the course is subjected to additional criteria based on the field of study with which it is associated (generally, a field of study relates to the UIS Program Code, a relationship that will disappear once a full transition to the HEI system is accomplished). Some fields of study have common criteria, and have been combined within one slide.
