Summary
Browsing with multi-faceted categorization may bring to many choices and too much browsing freedom to disorient users and increase the difficulty of information gathering. This paper takes context into account for multi-faceted categorization to help organize facets.
An experiment is carried out with two interfaces: ROAD interface which is basic, and COAD interface where attributes (facets) were arranged according to their contextual importance.
Context scenarios are constructed as: family size: single person, extended family; revenue/ expenditure ratio: low, high; purchase preference: luxury, speed. These factors could combine 8 different scenarios. Two of them are removed, leaving 6 scenarios.
The importance of different facets under different context scenarios was extracted, based on the frequencies the facets were clicked.
According to a user experiment, it was found that the interface COAD where facets were arranged according to contextual importance could promote ease-of-information-access, confidence in the decision making, and ease-of browsing.
