We describe a method for automatically generating Lexical Transfer Rules (LTRs) from word equivalences using transfer rule templates. Templates are skeletal LTRs, unspecified for words. New LTRs are created by instantiating a template with words, provided that the words belong to the appropriate lexical categories required by the template. We define two methods for creating an inventory of temp...

ion Validity Lexical values and categories must represent phenomena on the same level of abstraction for critical elements of theion for critical elements of the routine. • Carefully develop the lexical elements and

By merging syntactic categories of word classes, lexical categories were obtained. By demonstrating combination and type raising rules respectively from curried and uncurried perspectives, a category combination algorithm was presented, in which application, composition and type raising rules were sequentially examined, and the first available rule was selected. A Chinese CCG parser was develop...

Unsupervised learning of grammar is a problem that can be important in many areas ranging from text preprocessing for information retrieval and classification to machine translation. We describe an MDL based grammar of a language that contains morphology and lexical categories. We use an unsupervised learner of morphology to bootstrap the acquisition of lexical categories and use these two lear...

Early perceptual processing capabilities are likely to contribute to the categorization of lexical vs. grammatical words by newborns. This lexical categorization could be performed by detecting differences in the prosodic structure of these word categories. We demonstrated that this lexical categorization could be performed using many prosodic cues (duration, F0, energy and formants) automatica...

Lexically guided perceptual learning refers to the use of lexical knowledge to retune speech categories and thereby adapt to a novel talker’s pronunciation. This adaptation has been extensively documented, but primarily for segmental-based learning in English and Dutch. In languages with lexical tone, such as Mandarin Chinese, tonal categories can also be retuned in this way, but segmental cate...

In this paper, we try to understand how the human cognition identifies various sentiments expressed by different lexical indicators of sentiments in opinion sentences. We use the psychological index, Reaction Time (RT) for the analysis of various lexical indicators required for understanding the sentiment polarity. The test bed was developed using linguistic categories of lexical indicators of ...

Word retrieval deficits for specific grammatical categories, such as verbs versus nouns, occur as a consequence of brain damage. Such deficits are informative about the nature of lexical organization in the human brain. This study examined retrieval of grammatical categories across three languages in a trilingual person with aphasia who spoke Arabic, French, and English. In order to delineate t...

Spoken word recognition involves at least two basic computations. First is matching acoustic input to phonological categories (e.g. /b/, /p/, /d/). Second is activating words consistent with those phonological categories. Here we test the hypothesis that the listener’s probability distribution over lexical items is weighted by the outcome of both computations: uncertainty about phonological dis...
