About knowledge modelling: attributes

In the previous entry, I demonstrated three types of knowledge models. These models can help us structure the information we acquire from functional specifications, subject matter experts, the marketing department and - in some cases - our own observations. When combined they offer us different paths to our information.


We have looked at:
  1. Thematical models
  2. Taxonomies / concept models
  3. Composition models

A fourth model is called the Attribute model. An attribute model shows attributes and values: colors, specific characteristics, etc. An example is shown below:


With the attribute model we can describe all possible characteristics of a product range and link them to the actual products. This makes it possible to make an overview of all variations within a productrange. The models can help us choose between products.

Example: You call the service desk of the manufacturer of your TFT screen

Service desk employee: "Do you know the exact product type?"

You: "I am not sure, I could not find the product tag. I bought it in 2006"

Service desk employee: "Does it have a silver front or a black front?"

You: "It has a silver front"

Servce desk employee: "What color is the Power indicator?"

You: "It is red"

Service desk employee: "You have the SW457"

The Service desk employee can now open the specific information for this product type. When we use the same principle on a web site, we can help our users determine which type of product they have and lead them to the information they need.
