	Faceted classification - Wikipedia, the free encyclopedia
		In a faceted classification, subjects are divided into facets (aspects), and class numbers are synthesised from the classifications.
		Ranganathan and the Universal Decimal Classification are the two most prominent examples of faceted classification in the physical world, where for many years this approach to classification was thought of as something complicated, difficult to understand and exotic.
		Faceted classification is also used in software engineering to support software reuse.

	Ranganthan: Ahead of His Century
		Faceted classification is also called analytico-synthetic, named after the two main processes involved in the composition of a call number.
		Such a classification scheme is considered to be "hospitable" to all sorts of complex topics.
		Because the facets for one class are compiled independently of another class, this ensures that the terms chosen are specific to that class and are the current terms used by people in the field.

	IAwiki: FacetedClassification (Site not responding. Last check: 2007-10-25)
		Faceted classification is also called analytico-synthetic, named after the two main processes involved in the composition of a call number [an alphabetic or alphanumeric notation].
		Facets are "clearly defined, mutually exclusive, and collectively exhaustive aspects, properties or characteristics of a class or specific subject" ([Maple 1995])
		The classic example of a faceted information domain is wine, where any given bottle of fermented grape juice gets classified in a small number of "facets" such as varietal, location of origin, price bracket, cellaring, and food suitability.

	Faceted classification (User experience design resources)
		Faceted taxonomies have a major drawback that prevents their deployment and use for real and large-scale applications like the Web.
		The purpose of this study is to propose a simplified model for facet analysis that incorporates the principles of facet analysis proposed by both Ranganathan and the Classification Research Group.
		The purpose of this 1995 paper is to define what is meant by facet analysis, and to review briefly the history of facet analysis within the context of other types of subject analysis in libraries and within the context of information retrieval research.

		The Bibliographic Classification (BC2 or Bliss) is the leading example of a fully faceted classification scheme.
		The Classification (known as BC) was originally devised by Henry Evelyn Bliss and was first published in four volumes in the USA between 1940 and 1953.
		Bliss stated that one of the purposes of the Classification was to "demonstrate that a coherent and comprehensive system, based on the logical principles of classification and consistent with the systems of science and education, may be available to services in libraries, "to aid revision...

	Faceted Classification Glossary of Terms
		Facet: a group of headings which all define a certain method of classification.
		That is, a facet is a way in which a resource can be classified; for example, classified by color, classified by geography, classified by subject, etc. The wine demo uses three facets: Varietal, Region, and Price.
		Faceted Classification: In a strict faceted classification model, a resource is classified under one heading from each facet that applies to it.

	Techquila - Faceted Classification
		Using a faceted classification system it should be possible to retrieve any instance by drill-down through one of the facets until you reach the entry under which the instance is classified.
		However in order to really make use of a faceted classification system it is important to be able to determine what facets are defined in the classification system, and the type or types of association which define the hierarchical relationship between classes in each facet.
		This association asserts that the classification hierarchy used by the player of the Facet role is defined by associations of the type specified by the player of the Facet Hierarchy Type role.

	Faceted Classification
		A faceted classification differs from a traditional one in that it does not assign fixed slots to subjects in sequence, but uses clearly defined, mutually exclusive, and collectively exhaustive aspects, properties, or characteristics of a class or specific subject.
		Such aspects, properties, or characteristics are called facets of a class or subject, a term introduced into classification theory and given this new meaning by the Indian librarian and classificationist S.R. Ranganathan and first used in his Colon Classification in the early 1930s.
		One of the primary benefits of faceted classification is that even if you don’t know the name of an object, you can achieve a very accurate shared understanding of what it is by describing it in terms of several mutually exclusive categories of information.

	A Simplified Model for Facet Analysis
		The CRG looked to Ranganathan's theory of facet analysis to serve as the basis for all bibliographic classification systems, but modified aspects of this theory that it felt were too restrictive (Austin 1969; Classification Research Group 1985; Wilson 1972).
		The model could be used by designers of faceted classification systems and IR thesauri, because these designers might also need to consult a variety of sources to obtain the principles of facet analysis needed for their work.
		Faceted notation is certainly useful for indicating more clearly how subjects are derived, but could result in rather lengthy notation in the case of compound subject that are derived from different classes and facets.

		The idea for a faceted classification really began with the Dewey Decimal Classification (DDC) in which a standard number representing place (location) was appended to a subject number by a device now known as a facet indicator.
		However, Dewey did not develop the idea further and in the early 1930s, Ranganathan formalized the use of the fully faceted approach with his Colon Classification.

		A faceted classification differs from the traditional classification in that it does not assign fixed slots to each resource being referenced.
		In the library world faceted classifications are not new, however, there have been a number of significant technical hurdles that have had to be over come before this efficient and effective information retrieval could make a business impact.
		The benefit to the user, the information seeker, is that information is found based on their own context and requirements, retrieval does not require an in depth knowledge of a complex file structure or the input of complicated Boolean terms.

		Faceted classification allows for exploration directed by the user, where a large dataset is progressively filtered through the user's various choices, until arriving at a manageable set that meet the users' basic criteria.
		He is right in saying that the concept of facet analysis is not a new alternative to hierarchies of subject categories, although putting its application and use in the hands of users might be.
		The importance of facetted classification recognising the important work of Ranganathan and members of the British Classification Research Group in the 1950’s was recognized as research and development to improve access to information was undertaken from 1980 onwards at Huddersfield Polytechnic (subsequently the University of Huddersfield) and the National Library of Medicine in the USA.

	WDVL: The Web Librarian
		Basically, the facet development process begins by defining the subject to be covered by examining existing classifications or thesauri, or titles or objects in the perspective database.
		In a faceted classification scheme, the facets may be considered to be dimensions in a cartesian classification space, and the value of a facet is the position of the artifact in that dimension.
		Alternatively, a faceted classification scheme (multiple keywords) could replace the hierarchy with a directed acyclic graph permitting multiple links from category parents, which would improve the likelihood that relevant entries are found from a given starting point.

		Instead, a faceted classification system — in this instance, called a "guided navigation" system by Endeca, the company behind this implementation — the browsable interface changes with every choice so that it never shows you parameters that would result in an empty results list.
		Personally I don't think the LC classification block at the top is very useful for the types of searches that I do, but some people really like it.
		Faceted navigation, or guided navigation, term on which Endeca has been granted a patent (24th of May 2006), is a natural form of interaction at this stage.

		I'm not sure who was the first to coin it but it's a navigation method that seems to work very well when you have a large list of items you need to classify and browse.
		The most important thing to remember when creating facets is that they must be exclusive: a topic (or 'property', or 'value') can not be in facet A and also in facet B. 'cuisine', 'course' and 'season' are good facets because a season is never a course or a cuisine.
		Note that within a facet, the topics (like Chinese cuisine and Indian cuisine) don't have to be exclusive: a dish can be Chinese-Indian without problems.

	Faceted classification \| kika\|trip\|ee
		Most folks, when thinking about organizing objects or information, immediately think of a hierarchical, or taxonomic, organization; a top-down structure, where you start with a number of broad categories that get ever more detailed, until you arrive at the object.
		Faceted classification, on the other hand, is a bottom-up scheme.
		Here, each object is tagged with a certain set of attributes and values (these are the facets), and the organization of these objects emerges from this classification, and how a user chooses to access them.

	Wikis Aren't Enough
		In response to my post on a faceted classification web framework, Bill de Hóra pointed out that wikis can do classification already, via backlinks.
		My own blogging software allows for the classification of each entry; in fact, it allows multiple classifications for each entry (and although every entry of mine has such classifications, there isn't support yet for using the data for anything).
		Part of that is unintentional duplication (five different typings of “Cue Cat” for example); silly classifications are another reason (“dead zombie langauges rising from the dead” anyone?).
