Dealing with quantities, not physical phenomena. Specific quantities are declared in respective ontologies, e.g. :Strength and :hasStrength in http://www.agfa.com/w3c/2009/drugTherapy#. OWL Full quantity Property that can be quantified by the product of a numeric value and a unit value. Property of a phenomenon, body, or substance, where the property has a magnitude that can be expressed as a number and a reference. http://www.w3.org/2005/Incubator/w3pm/XGR-w3pm-20091008/#A physical quantity Physical property that can be quantified by the product of a numeric value and a unit value. measuring Quantifying a property by comparison with a standard. measurement Quantification of a property by comparison with a standard. number Quantity with the dimension of 1, without any physical unit. total Total set of something. part Part set of something. ratio Quantity of something as fractional representation of something else. E.g. 5 g sugar/100 ml water average Central tendency value of a data set. arithmetic mean Sum of all numbers of a set divided by the number of numbers in the set. minimum Smallest number of a set of numbers. maximum Largest number of a set of numbers. probability Numerical expression of the chance of something to happen. percentage Ratio of something to 100 of something more general. time Quantity as dimension in which events occur in sequence. frequency Quantity expressing the number of recurrent events per unit of time. number of recurrent events Count of recurrent events. length Any one-dimensional thing. surface Any two-dimensional thing. volume Any three-dimensional thing. mass Physical quantity equal to an object's resistance to changing either the speed or direction of its motion. The mass of an object is independent of gravity and therefore different from but proportional to its weight. thermodynamic temperature thermodynamic temperature measurement amount of substance Physical quantity proportional to the number of elementary entities which may be atoms, molecules, ions, electrons, or particles, the choice of which is dependent upon context and must be stated. amount-of-substance concentration Physical quantity expressing the amount of substance of something per unit of volume. speed Physical quantity expressing a change of position of something per change of time. velocity Vector physical quantity expressing a speed of something and its direction. concentration Physical quantity expressing the amount of something per unit of something else. mass concentration Physical quantity expressing the amount of mass of something per unit of something else. solution concentration Physical quantity expressing the amount of a solute per unit of a solution. pressure Physical quantity expressing the amount of force applied on a unit surface. electrical resistance Physical quantity expressing the opposition to the passage of an electric current. sample size Number of members in a test sample. sensitivity Probability a test is positive given a condition, e.g. a human is sick. The higher a sensitivity, the fewer true positive cases go undetected, e.g. the fewer sick people are considered healthy. specificity Probability a test is negative given the absence of a condition. The higher a specificity, the more true negative cases are detected, e.g. the fewer healthy people are considered sick. aspecificity Probability a test is positive given the absence of a condition. The higher an aspecificity, the more false positive cases are detected, e.g. the more healthy people are considered sick. false negative rate Probability a test is negative given a condition. The higher a false negative rate, the more true positive cases go undetected, e.g. the more sick people are considered healthy. accuracy Probability a test result is true. The higher an accuracy, the more test results are true. precision Probability a positive test result is true. The higher a precision, the more positive test results are true. negative predictive value Probability a negative test result is true. The higher a negative predictive value, the more negative test results are true. false discovery rate Probability a positive test result is false. The higher a false discovery rate, the more positive test results are false. digital size Physical quantity expressing the amount of information storage or communication in digital computing. increased Quantity being increased compared to a reference. Quantity having a bigger measurement value than a reference. decreased Quantity being decreased compared to a reference. Quantity having a smaller measurement value than a reference. normal Being compliant with a reference. State of a quantity having a measurement value within a normative reference value range. excessive Quantity being excessive compared to a reference. Quantity having a bigger measurement value than a normative reference value range. not excessive Quantity being not excessive compared to a reference. Quantity having a not a bigger measurement value than a normative reference value range. deficient Quantity being deficient compared to a reference. Quantity having a smaller measurement value than a normative reference value range. 229797004 once a day E.g. frequency of drug intake 229799001 twice a day E.g. frequency of drug intake 229798009 thrice a day E.g. frequency of drug intake Specifying a quantifiable property of something.
