The purpose of this paper is to suggest a view of word meaning on the type level based on “meaning potentials” rather than on reified type meanings founded on either of the two traditional approaches of abstract generalization (Gesamtbedeutung) and typical or basic meaning (Grundbedeutung). It is suggested that actual meaning on the occurrence level is produced by context sensitive operations o...

In this paper we investigate several hypotheses concerning document relevance ranking for biological literature. More specifically, we focus on three topics: performance, risk of local searching, and homonymy recognition. Surprisingly, we find that a simple ranker based on the occurrence of a single word performs best. Adding this word as a new search term to each query yields even better resul...

Children face ve central diiculties when learning the vocabulary of their native language: learning from multi-word utterances, bootstrapping from an empty mental lexicon, referential uncertainty, noise, and homonymy. These diiculties are modeled formally via a simpliied lexical acquisition task called the mapping problem. Algorithms for solving this mapping problem are developed, based on the ...

This chapter proposes a conception of lexical meaning as use-potential, in contrast to prevailing atomistic and reificational views. The issues are illustrated on the example of spatial expressions, pre-eminently prepositions. It is argued that the dichotomy between polysemy and semantic generality is a false one, with expressions occupying points on a continuum from full homonymy to full monos...

A total of 114 accessions putatively corresponding to 69 local grape cultivars from Campania (Southern Italy) were analysed with 8 microsatellite markers (VVS2, VVMD5, VVMD7, VVMD25, VVMD27, VVMD31, VrZAG62 and VrZAG79) in order to evaluate their genetic diversity and relationships. According to their unique genotype at SSR loci finally 56 varieties were found. Interesting cases of synonymy, i....
