What is Faceted navigation?
Faceted navigation "allows the users to navigate the information space by progressively selecting desired facets of the information items."
Faceted navigation is extremely useful for large collections of documents. Instead of defining navigation paths beforehand (the top down approach as Yahoo does), the users can pick and choose the information part that they find important. With each pick they filter the total document set to reach a managable set or even one final result. This is a bottom-up approach to describing information.
This is done by describing documents (or any other object) as a collection of properties, or facets. Material properties of a document (language, date) can be used as facets, but also subject matter (topic classification).
Each facet group becomes a navigation item. For household appliances we may have Vacuums, Refridgerators, Toasters. If we select Toasters, a new menu is shown, containing for instance brands, prize ranges, with or without warming rack. We can select toasters cheaper than 30 dollars, and then from these cheap toasters the ones that may hold 4 slices of bread. Finally we end up with 3 toasters
A faceted navigation is a navigation system which offers multiple facets of navigation to a single piece of information. This is done by using Faceted classification to group bits and pieces of information together. (definition Wikipedia)
Unlike a simple hierarchical scheme, faceted classification gives the users the ability to find items based on more than one dimension. For example, some users shopping for jewelry may be most interested in browsing by particular type of jewelry (earrings, necklaces), while others are more interested in browsing by a particular material (gold, silver). "Material" and "type" are examples of facets; earrings, necklaces, gold, silver are examples of facet values. (source: Web Design Practices | Faceted Classification)

Hm, can't believe that it's more than a year since Renauds last post. Have you seen sites were faceted like navigation is done by TWiki? Then please post a link here.
