2. In designing a taxonomy one has to define a priori appropriate terms and their subterms However as pointed out long ago by Ranganathan in the 1920s the design of a taxonomy can be done in a more convenient and a more systematic manner if we first identify a number of different aspects of the domain and then design one taxonomy per aspect This process results in a faceted taxonomy 1 e a set of taxonomies called facets For example suppose that we want to index Hotel home pages and suppose that we want to provide access to these pages according to three facets a the Place of the hotels b the Sports that are possible in these hotels and c the Facilities that they offer The next figure shows a faceted taxonomy Places Sports Facilities Earth AllSports MA Greece Finland SeaSports WinterSports Olympus Crete Cefalonia at a eo A WindSurfing SnowSki Rethimno Heraklio Picture 1 Faceted taxonomies Each object here hotel home page can now be indexed using a compound term i e a set of terms containing one or more terms from each facet For example a hotel in Crete providing sea ski and wind surfing facilities would be indexed by the compound term Crete SeaSki Windsurfing 2 3 What is the Compound Term Composition Algebra CTCA Notice that several compound terms over the above faceted taxonomy are meaningless For instance we cannot do any winter sport in the Greek islands Crete and Cefalonia as they n
