'Mass terms', words like water, rice and traffic, have proved very difficult to accommodate in any theory of meaning since, unlike count nouns such as house or dog, they cannot be viewed as part of a logical set and differ in their grammatical properties. In this study, motivated by the need to design a computer program for understanding natural language utterances incorporating mass terms, Harry Bunt provides a thorough analysis of the problem and offers an original and detailed solution. An (...) extension of classical set theory, Ensemble Theory, is defined, and this provides the conceptual basis of a framework for the analysis of natural language meaning which Dr Bunt calls Two-level model-theoretic semantics. The validity of the framework is convincingly demonstrated by the formal analysis of a fragment of English including sentences with quantified and modified mass terms. Separate chapters of the book are devoted to an axiomatic definition of Ensemble Theory and a detailed discussion of its status as a mathematical formalism. (shrink)

previous theories and the relevance of those criticisms to the new accounts. Additionally, we have included a new section at the end, which gives some directions to literature outside of formal semantics in which the notion of mass has been employed. We looked at work on mass expressions in psycholinguistics and computational linguistics here, and we discussed some research in the history of philosophy and in metaphysics that makes use of the notion of mass.

This volume covers a broad spectrum of research into the role of events in grammar. It addresses event arguments and thematic argument structure, the role of events in verbal aspectual distinctions, events and the distinction between stage and individual level predicates, and the role of events in the analysis of plurality and scope relations. It is of interest to scholars and students of theoretical linguistics, philosophers of language, computational linguists, and computer scientists.

This dissertation provides a model-theoretic semantics for English sentences atttributing a property or action to a group of objects, either collectively or distributively. It is shown that certain adverbial expressions select for collective predicates; therefore collective and distibutive predicates must be distinguishable. This finding is problematic for recent accounts of distributive predicates which analyze such predicates as taking group-level arguments, and hence as not distinguishable from collective predicates. ;A group-level treatment of distributives is possible, however, if predicate denotations are relativized (...) to a set of events for which a part/whole relation is defined. An event in which a group performs an action distributively will have subevents in which each of the group's members perform the same action; an event in which the group performs the action collectively will not. ;This analysis also makes possible an account of the fact that adverbials expressing collective action commonly have an additional use expressing spatial proximity, both in English and cross-linguistically. . A spatial "trace" function on the set of events allows formal definitions for the spatial uses of such adverbials to exactly parallel the definitions for the collectivizing uses. ;The dissertation also provides arguments for a set-theoretic model for plurality, in which the group membership relation is distinct from the subgroup relation. ;Certain quantifiers are shown sensitive to distinction between different sorts of group-level event. To accommodate this fact, it is suggested that verbal denotations provide, for each event, both an "inclusion set" and an "exclusion set"--corresponding roughly to positive and negative denotations. If the inclusion and exclusion sets are allowed under certain circumstances not to complement each other, correct results obtain. ;The splitting of verbal denotations into inclusion and exclusion sets also allows the solution of certain problems in previous accounts of the semantics of subject-verb agreement for number. The dissertation closes with a defense of the hypothesis that agreement is conditioned primarily by the semantics. (shrink)

One of the goals of a certain brand of philosopher has been to give an account of language and linguistic phenomena by means of showing how sentences are to be translated into a "logically perspicuous notation" (or an "ideal language"—to use passe terminology). The usual reason given by such philosophers for this activity is that such a notational system will somehow illustrate the "logical form" of these sentences. There are many candidates for this notational system: (almost) ordinary first-order predicate logic (...) (see Quine [1960]), higher-order predicate logic (see Parsons [1968, 1970]), intensional logic (see Montague [1969, 1970a, 1970b, 1971]), and transformational grammar (see Harrnan [1971]), to mention some of the more popular ones. I do not propose to discuss the general question of the correctness of this approach to the philosophy of language, nor do I wish to adjudicate among the notational systems mentioned here. Rather, I want to focus on one problem which must be faced by all such systems—a problem that must be discussed before one decides upon a notational system and tries to demontrate that it in fact can account for all linguistic phenomena. The general problem is to determine what we shall allow as linguistic data; in this paper I shall restrict my attention to this general problem as it appears when we try to account for certain words with non-singular reference, in particular, the words that are classified by the count/ mass and sortal/non-sortal distinctions.
