Inheritance in Natural Language Processing
In this introduction to the special issues, we begin by outlining a concrete example that indicates some of the motivations leading to the widespread use of inheritance networks in computational linguistics. This example allows us to illustrate some of the formal choices that have to be made by those who seek network solutions to natural language processing (NLP) problems. We provide some point...
متن کاملNatural Inheritance and Social Policy
Whf.n investigating any subject, the student of science should not hesitate long before endeavouring to frame some theory or general law by means of which all the facts known to him would be brought into harmonious relationship with each other. Such a provisional theory having been suggested, exceptional facts or out of the way occurrences will be of especial value in testing it; for either, be...
متن کاملInheritance of natural seed-coat cracking in chickpea.
A spontaneous mutant with natural seed-coat cracking, designated "cracked seed-coat mutant (CSM)," was identified in chickpea (Cicer arietinum L.) from an F(2) population of a cross ICRISAT chickpea (ICC) 10301 × ICC 12430. The extent of seed-coat cracking (SCC) varied widely from a minute to several wide cracks. Seed coats showed cracks before seeds were fully developed and the plants had reac...
متن کاملPopulation thinking and natural selection in dual-inheritance theory
A deflationary perspective on theories of cultural evolution, in particular dual-inheritance theory, has recently been proposed by Lewens. On this 'pop-culture' analysis, dual-inheritance theorists apply population thinking to cultural phenomena, without claiming that cultural items evolve by natural selection. This paper argues against this pop-culture analysis of dual-inheritance theory. Firs...
متن کاملOn the Inheritance of Natural Antisheep Agglutinins in Mice of Inbred Strains.
REVIOUS studies of DAVIDSOHN and STERN (1949, 1950) and of STERN and P DAVIDSOHN (1954) have demonstrated significant differences in distribution of titers of natural agglutinins for sheep red cells within and between inbred strains of mice. Results obtained on substantial numbers of mice of 13 strains are summarized in table 1. These mice, which consisted of approximately equal numbers of male...
