Quote: Roget used two parallel columns to show words and their opposites on the same page [»rogePM_1853, OK]

Quote: Dewey paraphrased: organize your books so that you can find them, and never mind the philosophy [»sparK7_1972]

Quote: Roget built his thesaurus for practical utility in locating words. He avoided needless refinement [»rogePM_1853, OK]

Quote: index consistency highest for checktags, a small set of basic-level categories preprinted on the indexing form [»funkM4_1983]

Quote: basic classes occur in the middle of the class hierarchy but object-oriented class design proceeds from top to bottom [»taivA11_1997]

Quote: basic-level categories such as 'chair' or 'water' are human-sized; they depend on how people interact with objects [»lakoG_1987]

Quote: basic level of abstraction carries the most information; most differentiated; real-world [»roscE7_1976]

Quote: basic categories maximize cue validity; superordinate categories share fewer attributes; subordinate categories share more attributes

Quote: for nonbiological taxonomies, basic categories described by typical muscle movements; e.g., sitting down on a chair [»roscE7_1976]

Quote: objects in a basic category have similar shapes

Quote: have mental images of concrete objects in basic categories; superordinate objects not easily identified, subordinate objects like the corresponding basic category [»roscE7_1976]

Quote: for nonbiological taxonomies, basic categories have more attributes than superordinate categories [»roscE7_1976]

Quote: for nonbiological taxonomies, basic categories are identified by shared attributes

Quote: sorting objects into basic level categories is virtually perfect; significantly better than sorting into superordinate categories [»roscE7_1976]

Quote: nearly total agreement in the use of basic level names for objects; superordinate and subordinate names seldom used for free-naming [»roscE7_1976]

Quote: a child's first utterances of concrete nouns are at the basic level of abstraction; basic level names used almost exclusively during free naming [»roscE7_1976]

Quote: classification is for describing uniformities of collections of instances [»wegnP10_1986]

Quote: a category is a number of objects which are considered equivalent; e.g., dog, animal [»roscE7_1976]

Quote: things are classified into types for naming scope, validity constraints, and relationship domains; groups are mutually exclusive [»kentW_1978]

Quote: in ML, words are grouped into categories which can define properties of their members [»spooCR4_1986]

Quote: an entity set is a grouping of entities with similar properties [»senkME1_1973]

Quote: similar objects grouped by classes which prescribe common attributes and constraints [»borgA10_1986]

Quote: object-oriented programming distinguishes general properties of a class from specific properties of an instance

Quote: a class of objects is defined by a pattern giving a set of attributes and a set of actions [»handP_1981]

Quote: categories are defined by patterns; includes data types, classes, procedures, and functions [»handP_1981]

Quote: define categories by family resemblance instead of criterial features

Quote: Kevo uses family resemblance instead of explicitly sharing object representations [»taivA11_1997]

Quote: the focal colors serve as prototypes or cognitive reference points for a category; other physical categories have prototypes

Quote: prototypical members of a category share the most attributes with other members of the category and the fewest attributes from other categories; experiments with natural and artificial categories [»roscE_1975]

Quote: statements about individuals and classes are different logical types; hard to predict one from the other [»bateG_1979]

Quote: a Smalltalk class is also an object; it handles messages

Quote: object classes are themselves objects; can attach definitional information and sometimes attributes [»borgA1_1985]

Quote: a taxonomy is a hierarchy of categories; most abstract is the root [»roscE7_1976]

Quote: species can not be classified into circles or prearranged groups

Quote: no species has come into existence twice

Quote: a Perceptron has no notion of irrelevant objects or trash; only uncertainty

Quote: although IS-A links are widely used for classification, they have different meanings in different knowledge-representation systems [»bracRJ10_1983]

Quote: using IS-A links for default properties is insufficient for complex concepts and interacts badly with cancellation [»bracRJ10_1983]

Quote: IS-A links may indicate subset/superset, a kind of, conceptual containment, role value restriction, or a set's characteristic type [»bracRJ10_1983]

Quote: the meaning of an IS-A link depends on understanding its nodes [»bracRJ10_1983]

Quote: IS-A between sets typically indicates subsets; IS-A between predicates typically indicates that A follows from B [»bracRJ10_1983]
