The purpose of this study is to evaluate the validity of measuring grammatical diversity with a specifically designed Lexical Diversity Assessment Tool (LDAT). A secondary objective is to use LDAT to determine if the level of difficulty assigned to English as a Second Language (ESL) texts corresponds to increases in grammatical, lexical, and temporal diversity. Other methods of lexical diversit...

Problems with the lexical substitution mechanism of the C preprocessor are well known. We resolve these problems with a new syntax-based substitution mechanism for C++ based on meta-variables and metafunctions. Implementation of these meta-concepts in a C++ style leads naturally to meta-expressions and then meta-statements and a generalisation of C++ syntax. We show how meta-compilation renders...

My primary research is in the representation of semantic information and its use in natural language processing applications. The meaning of a sentence is a central aspect of natural language understanding, yet an elusive one, since there is no accepted methodology for determining meaning. There is not even a consensus on criteria for distinguishing word senses, as can easily be seen by compari...

this paper examines the semantic contribution of -?r and -andeh suffixes in persian based on lieber’s (2004) lexical semantic representation. this framework using six semantic features ([material], [dynamic], [location], [ieps] , [b] and [ci] and a principle called coordination principle studies the semantic contribution of lexical items including affixes and their functions in compounding, der...

Abstract: The current research examines how the representation of imagined events is constrained by Grammatical Aspect (imperfective/perfective), Lexical Aspect (activities/accomplishments), and first versus third person perspective taking. In one experiment, participants imagined events based on written cues that framed events as completed or as ongoing (e.g., I was exercising). In a follow-up...

The current study, setting a two-fold goal, attempted to see whether the preemptive focus on form (FonF) under either planned or unplanned conditions could contribute to increasing lexical diversity in written narratives and, second, to find whether there was a trade-off between the lexical diversity and accuracy. To this end, 32 beginner learners were selected following a Quick Oxford Placemen...

The aim of this project is to elaborate a theory of natural language lexicons for Combinatory Categorial Grammar (CCG), a mildly contextsensitive, polynomially time-parsable variant of categorial grammar. This theory will have both a descriptive aspect, exploring the use of appropriate formal machinery for expressing lexical generalisations, and an explanatory aspect, accounting for observed pa...

chology and, therefore, a chapter on the topic must be selective. This chapter will first place the relevant issues in a historical context and then review the basic visual word recognition phenomena within the context of current models. It will then be argued that any successful model of visual word recognition needs to incorporate the assumption of “interactivity,” that is, that the various c...

We propose an automatic approach towards determining the relative location of adjectives on a common scale based on their strength. We focus on adjectives expressing different degrees of goodness occurring in French product (perfumes) reviews. Using morphosyntactic patterns, we extract from the reviews short phrases consisting of a noun that encodes a particular aspect of the perfume and an adj...
