  • Collocational knowledge is necessary for language generation. The problem is that collocations come in a large variety of forms. They can involve two, three or more words, these words can be of different syntactic categories and they can be involved in more or less rigid ways. This leads to two main difficulties: collocational knowledge has to be acquired and it must be represented flexibly so that it can be used for language generation. We address both problems in this paper, focusing on the acquisition problem. We describe a program, X t r a c t , that automatically acquires...

  • This paper descrlbes how meanings are represented in a semantic grammar for a fragment of English in the logic programming language Prolog. The conventions of Definite Clause Grammars are used. Previous work on DCGs with a semantic component has used essentially first-order formulas for representing meanings. The system described here uses formulas of the typed ~-calculus.

  • In this paper we describe an approach to constraint based syntactic theories in terms of finite tree automata. The solutions to constraints expressed in weak monadic second order (MSO) logic are represented by tree a u t o m a t a recognizing the assignments which make the formulas true. We show that this allows an efficient representation of knowledge about the content of constraints which can be used as a practical tool for grammatical theory verification. We achieve this by using the intertranslatability of formulae of MSO logic and tree a u t o m a t a...

  • This paper looks at representing paraphrases using the formalism of Synchronous TAGs; it looks particularly at comparisons with machine translation and the modifications it is necessary to make to Synchronous TAGs for paraphrasing. A more detailed version is in Dras (1997a).

  • The question we have addressed here is to define the size and composition of the corpus we would need in order to get necessary and sufficient information for Machine Learning techniques to induce that type of information. Representativeness of a corpus is a topic largely dealt with, especially in corpus linguistics. One of the standard references is Biber (1993) where the author offers guidelines for corpus design to characterize a language.

  • In order to represent speech acts, in a multi-agent context, we choose a knowledge representation based on the modal logic of knowledge KT4 which is defined by Sato. Such a formalism allows us to reason about knowledge and represent knowledge about knowledge, the notions of truth value and of definite reference.

  • Linear algebra is the branch of mathematics concerning vector spaces, often finite or countably infinite dimensional, as well as linear mappings between such spaces. Such an investigation is initially motivated by a system of linear equations in several unknowns. Such equations are naturally represented using the formalism of matrices and vectors

  • As can be seen in Table 1, the pre-service teachers had diverse linguistic and cultural backgrounds. 2 Selection of the pre-service teachers, while not designed to be representative, provided a broad student teacher perspective on issues related to teaching ESL writing. The participants represented a diverse set of backgrounds and experiences. Seven were native English speakers. Five were second language speakers of English, with Korean, French and Portuguese as their first language backgrounds.

  • .Representing Landscape Architecture It has been said that we can realize only what we can imagine; but to realize what we imagine, we must convey those ideas to others as well as present them to ourselves. We use images, models, and words—alone or in combination—to conceive, study, test, construct, and evaluate new landscapes or modify old ones. Given the transient nature of most landscapes—always growing, always changing— landscape representation presents a special challenge. It is by no means neutral in a political sense or even in terms of design evaluation.

  • Expert systems represent a branch of artificial intelligence aiming to take the experience of human specialists and transfer it to a computer system. The knowledge is stored in the computer, which by an execution system (inference engine) is reasoning and derives specific conclusions for the problem. The purpose of expert systems is to help and support user’s reasoning but not by replacing human judgement. In fact, expert systems offer to the inexperienced user a solution when human experts are not available....
