3.4. Measures of Semantic Relatedness 691. only adjectival words, adverbial words, numerals or punctuation occur betweenN and A (only iterates across tokens and applies the specified condition),2. there is an occurrence of być (to be) between N and A (an attributive use ofbyć) and there is no other noun between N and A, which could be the real headfor the modification by A.The second condition is also constrained by the requirement of N not being in thegenitive case: a noun in genitive can also be a modifier, so predictions may be lessaccurate.VsbC is based on the nominal case of the target LU N – a potential subject and theagreement on number and gender or only gender, depending on the verb form, betweenN and a lexical element V – a potential predicate for N. Such an agreement is tooweak evidence, so the presence of any other potential subject N ′ intervening in thispossible association is tested. N ′ can occur at any position in the sentence, so a rangeof possibilities is tested.NcC depends only on the case of the two nominal LUs which may be coordinate:the target LU N and the lexical element M. We identify M’s position and we checkthe equality of case values of N and M. Next, the tokens occurring between N andM are also tested for representing only a limited number of grammatical classes.and(rlook(1,end,$B,and(in(flex[$B],{nominal grammatical classes }),equal(base[$B],{particular base form }),equal(cas[$B],{gen}) )),only(1,$-1B,$Ad, or(in(flex[$Ad],adverbial grammatical classes ),and(in(flex[$Ad],{nominal grammatical classes }),equal(cas[$Ad],{gen})),and(in(flex[$Ad],{adverbial grammatical classes and numerals }),agrpp(0,$Ad,{nmb,gnd,cas},3)))) )Figure 3.6: Parts of a morphosyntactic constraint which describes nominal LUs via the modification bya nominal LU in the genitive case (NmgC)NmgC, presented schematically in Figure 3.6, identifies modification by a specificnoun in genitive, which represents an ambiguous or even vague semantic relation. Theconstraint does not depend on any morphosyntactic agreement; that makes it hard to
