Connectionist approaches to word learning and word recognition imply that the units of lexical representation are not part of a fixed architecture. If the size of stored units is determined by extracting co-occurrence regularities, then we expect the lexicon to include multi-word units which have become entrenched due to repeated use. Experiments using Reicher's two-alternative forced-choice pr...

In order to solve problems of reliability of systems based on lexical repetition and problems of adaptability of languagedependent systems, we present a context-based topic segmentation system based on a new informative similarity measure based on word co-occurrence. In particular, our evaluation with the state-of-the-art in the domain i.e. the c99 and the TextTiling algorithms shows improved r...

Natural languages contain many multi-word sequences that do not display the variety of syntactic processes we would expect given their phrase type, and consequently must be included in the lexicon as multiword units. This paper describes a method for identifying such items in corpora, focussing on English verb-noun combinations. In an evaluation using a set of dictionary-published MWEs we show ...

Previous research on spoken word recognition has demonstrated that identification of a phonetic segment is affected by the lexical status of the item in which the segment occurs. W. F. Ganong (1980) demonstrated that a category boundary shift occurs when the voiced end of 1 voice-onset time continuum is a word but the voiceless end of another series is a word; this is known as the "lexical effe...

In several languages compound words form orthographic units, which complicates the task of ensuring good lexical coverage for large vocabulary continuous speech recognition (LVCSR). A common approach to the problem consists of first recognizing the compound constituents, followed by an automatic recompounding process. We describe an accurate compound module, which combines a rule-based approach...

This study investigated whether Japanese listeners learning English employ two types of lexical information (word frequency and neighborhood density) when they recognize English words. English words recorded by a native speaker of English and a native speaker of Japanese were presented to Japanese university students in a noise condition. The results of word recognition scores showed that Japan...

The rate of lexical replacement estimates the diachronic stability of word forms on the basis of how frequently a proto-language word is replaced or retained in its daughter languages. Lexical replacement rate has been shown to be highly related to word class and word frequency. In this paper, we argue that content words and function words behave differently with respect to lexical replacement ...

Formulaic sequence (FS) is a general term often used to refer to various types of recurrent clusters. One particular type of FSs common in different registers is lexical bundles (LBs). This study investigated whether LBs are stored and processed as a whole in the mind of language users and whether their functional discourse type has any effect on their processing. To serve these objectives, thr...

Orthographically/phonologically related primes have typically been found to facilitate processing of target words. This phenomenon is usually explained in terms of spreading activation between nodes for orthographically/phonologically similar words in lexical memory. The phenomenon was explored in a series of studies involving the manipulations of prime and target type (word or picture) and pri...
