	Stellar classification - Wikipedia, the free encyclopedia
		In astronomy, stellar classification is a classification of stars based initially on photospheric temperature and its associated spectral characteristics, and subsequenly refined in terms of other characteristics.
		The Yerkes spectral classification, also called the MKK system from the authors' initials, is a system of stellar spectral classification introduced in 1943 by William W. Morgan, Phillip C. Keenan and Edith Kellman of Yerkes Observatory.
		This classification is based on spectral lines sensitive to stellar surface gravity which is related to luminosity, as opposed to the Harvard classification which is based on surface temperature.

	classification. The Columbia Encyclopedia, Sixth Edition. 2001-05
		The original purpose of biological classification, or systematics, was to organize the vast number of known plants and animals into categories that could be named, remembered, and discussed.
		Modern classification is part of the broader science of taxonomy, the study of the relationships of organisms, which includes collection, preservation, and study of specimens, and analysis of data provided by various areas of biological research.
		Little interest was shown in classification until the 17th and 18th cent., when botanists and zoologists began to devise the modern scheme of categories.

	Classification of Igneous Rocks
		For instance, the classification of minerals is based on common anoins since minerals sharing common anions often have similar physical properties (i.e hardness, cleavage etc.).
		As discussed earlier, texture is used to subdivide igneous rocks into two major groups: (1) the plutonic rocks, with mineral grain sizes that are visible to the naked eye, and (2) the volcanic rocks, which are usually too fine-grained or glassy for their mineral composition to be observed without the use of a petrographic microscope.
		As noted in the sidebar to the left, this is largely a genetic classification based on the depth of origin of the rock (volcanic at or near the surface, and plutonic at depth).

		Identification is the practical use of classification criteria to distinguish certain organisms from others, to verify the authenticity or utility of a strain or a particular reaction, or to isolate and identify the organism that causes a disease.
		Classification and identification of an organism should be based on its overall morphologic and biochemical pattern.
		A question of classification that is based on scientific data (for example, whether a species, on the basis of its biochemical or genetic characteristics, or both, should be placed in a new genus or an existing genus) is not settled by the Judicial Commission, but by the preference and usage of the scientific community.

		The classification was originally developed by Herbert Putnam with the advice of Charles Ammi Cutter in 1897 before he assumed the librarianship of Congress.
		It was influenced by Cutter Expansive Classification and DDC, designed for the use by the Library of Congress.
		It has been criticized as lacking a sound theoretical basis; many of the classification decisions were driven by the particular practical needs of that library, rather than considerations of epistemological elegance.

	Group Classification on National ID Cards - Jim Fussell - 15 Nov 2001 (Site not responding. Last check: 2007-10-22)
		Group classification on ID cards or other official personal documents (passports, residence permits, etc.) force a person to be affiliated with a governmentally-defined group and expose persons to profiling and human rights abuses based upon their group identity.
		Classifications on ID cards are instead a facilitating factor, making it more possible for governments, local authorities or non-state actors such as militias to more readily engage in violations based on ethnicity or religion.
		The special significance of classification on the ID cards may be heightened at moments of crisis or in regions of conflict, such as in May 1998 in Indonesia or in Tibet in China.

		In this respect, one of the Classification’s strengths is its grounding in objective data on institutional behavior: to the extent that it differentiates institutions by mission, it is mission as revealed in institutional action.
		The 2000 edition of the Carnegie Classification retains the basic structure that was established in 1971, with two changes: we have reduced the number of categories of doctorate-granting institutions from four to two, and we have added a new category of baccalaureate colleges.
		This ambiguity near category borders is another reason why the Classification should not be interpreted as characterizing the fundamental nature of an institution, and why the rigid typing of institutions based on the Classification may not always be appropriate.

		Classification is essentially an effort by scientists to discover, reconstruct, and clarify the phylogeny, or evolutionary history, of an organism or group of organisms.
		In cladistic analysis, each feature, or character, is viewed as a primitive character (common to an entire group) or a derived character (that arose in the evolution within the group).

	A Definition of Thesauri and Classification as Indexing Tools
		There are many classification schemes and there are also many classifications of knowledge which can be confused with bibliographic or documentary classifications as they can both cover a specific field of knowledge or the whole system of knowledge.
		The main difference between classification of knowledge and bibliographic classification is that bibliographic/documentary classifications both special, such as NLM, INSPEC etc. or general, such as Dewey Decimal Classification, Library of Congress Classification, Universal Decimal Classification, are indexing systems designed to deal with knowledge recorded in documents.
		Knowledge classification can be, and often is, TAXONOMIC (sometimes called 'entity classification') like the classification of zoology, classification of plants, or classification of chemical elements (which means that they are going to list one concept in one place only in the classification structure).

	Faceted Classification (Site not responding. Last check: 2007-10-22)
		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.
		Most classification experts and professional indexers think of back-of-the-book indexes as very different from classification schema, but a close look at good indexes shows that they exhibit many of the characteristics associated with faceted classification.
		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.

	ToL: Phylogeny or Classification
		A clear distinction between the concepts of phylogeny and classification is critical for understanding the nature of the project.
		Calling "Phylogeny" by the name "classification" confuses and (in the eyes of many) demeans phylogenetic biology in the same way calling "molecular biology" by the name "classification" would.
		Most researchers feel that the groups we give names to in our classifications should correspond to single branches or clades on the phylogeny: if we wish to talk about the history of a group, it is easier to do so if the named entities are cohesive portions of that history.

	Classification
		The classification system also reflects the manner by which the various groups and species of organisms arose during the course of evolution by branching off ancestral species.
		We're suggesting that at a certain point in bird evolution a species arose with a hooked bill and other characteristics today associated with shrikes, and this species became the ancestor of all the many shrikes that exist today, the proto-shrike, the first of its genus.
		Once you learn the classification of many organisms you'll see that all the subdivisions actually manifest themselves as branches arising from larger branches.
