taxonomy

 [tak-son´ah-me]
the orderly classification of organisms or lists into appropriate categories (taxa), with application of suitable and correct names. adj., adj taxonom´ic.
numerical taxonomy a method of classifying organisms solely on the basis of the number of shared phenotypic characters, each character usually being given equal weight; used primarily in bacteriology.

tax·on·o·my

(taks-on'ŏ-mē),
The systematic classification of living things or organisms. Kingdoms of living organisms are divided into groups (taxa) to show degrees of similarity or presumed evolutionary relationships, with the higher categories being larger, more inclusive, and more broadly defined, and the lower categories being more restricted, with fewer species more closely related. The divisions below kingdom are, in descending order: phylum, class, order, family, genus, species, and subspecies (variety). Infra- and supra- or sub- and super- categories can be used when needed; additional categories, such as tribe, section, level, group, etc., are also used.
[G. taxis, orderly arrangement, + nomos, law]

taxonomy

(tăk-sŏn′ə-mē)
n. pl. taxono·mies
1. The classification and naming of organisms in an ordered system that is intended to indicate natural relationships, especially evolutionary relationships.
2. The science, laws, or principles of classification.
3. An ordered arrangement of groups or categories: a taxonomy of literary genres.

taxonomy

The science or principles of biological classification and the assignment of appropriate names to species.

taxonomy

the study of the CLASSIFICATION of organisms. Classical taxonomy involves the use of morphological features, cytotaxonomy the use of somatic chromosomes, experimental taxonomy involves the determining of genetical interrelationships, and numerical taxonomy involves quantitative assessments of similarities and differences in an attempt to make objective assessments.

Methodology for Gini Metric and Taxonomic Diversity Analysis: The diversity of the research (in the three journals) is determined by the Gini metric computed over the fractions of papers classified under each of the various classifications in four selected taxonomic categories, the two topical taxons (school of thought and foundation discipline), and the two methodological taxons (research method and mode of reasoning).
Given that the taxonomy classifies companies using local cluster data, it would be important to consider how this might bias the statistical generation of taxonomic categories. If all multimarket companies (looking at the 2001 AHA data, nearly 40 percent of the hospital companies have facilities in more than one market) were made up exclusively of local market clusters, then perhaps averaging across their markets might provide a passable indicator of their typical patterns of local service sharing.
Using 2001 data, Table 1 compares companies classified by the five taxonomic categories on three system characteristics that are expected to be consistent with the classification bias--percent hospitals that are freestanding, number of system hospitals, and average distance for each system hospital to its system center.
Secondly, we analyzed the fields containing information on the action of constraining factors (primary, secondary or tertiary) for soil development or productive activities, even if they were not reflected in the taxonomic categories. In this case, special attention was paid to waterlogging, flooding, and drainage impairment, since they may indicate wetland occurrence.
Abundance estimates were based on 4163 km of effort in Beaufort sea states [less than or equal to] 4 and 217 on-effort sightings of cetacean species or other taxonomic categories (Fig.
Abundances for other species or taxonomic categories ranged from 20 to 6086 There were an estimated 77,139 (0.23) cetaceans in the study area.
The resulting semantic signature ranks all the taxonomic categories, which have been linked to each document token, along with additional information including the location of these tokens in the document, etc.
Virus classification places the viruses in a series of classes or taxonomic categories with a hierarchical structure, the ranks being the species, genus, family, and order.
Species are thus very different from the other taxonomic categories used in virus classification such as genera and families.
Whether dealing with definition of terms or taxonomic categories, consistency across fields is paramount.
