Topic - Origins

based on the academic fields of:

Requirements Engineering&

Domain Ontologies

Topic - Purpose

Creating a method that complements requirements documents in specific domains

Without using a domain expert!

Topic – Main phases

1. obtain requirements

3. Evaluate the quality of the requirements

4. Update the list of requirements according to

evaluation steps

2. Map requirements onto domain ontology

4a. Completeness4d. Consistency

4b. Unambiguous4c. Correctness

1. Development of domain ontologies&

2. Application of ontological techniques to requirements engineering

Example

A felon registration system

Example

Step 1: Create or find a DO for a registration system

specific to felons(DAML ontology library)

Example

Step 2: Gather initial requirements

e.g. Every felon needs a unique identifier

Every felon needs to have a fotoEtc…

Example

Step 3: Map the requirements you created onto a DO

Example

Step 4: Calculate the 4 quality measures

Is it complete?Is it correct?

Is it consistent?Is it ambiguous?

Example

Step 5:When the measures are not sufficiently high

Update the list of requirements

DO says that each unique identifier is composed of two componentsState & number

New Req: Every felon needs a state name Every felon needs a number

Example

Step 6:Go back to step 2
