Domain adaptation of natural language processing systems is challenging because it requires human expertise. While manual effort is effective in creating a high quality knowledge base, it is expensive and time consuming. Clinical text adds another layer of complexity to the task due to privacy and confidentiality restrictions that hinder the…

Agrammatism is a frequent sequela of Broca's aphasia that manifests itself in omission and/or substitution of the grammatical morphemes in spontaneous and constrained speech. The hierarchical structure of syntactic trees has been proposed as an account for difficulty across grammatical morphemes (e.g., tense, agreement, and negation). Supporting…

A discussion of grammatical disorders in aphasia considers an area of ambiguity. In the work of one researcher, impairment of logico-grammatical relations is associated with semantic aphasia, not efferent-motor aphasia. In Western studies, efferent-motor aphasia is associated with impaired comprehension and production of grammar. In order to…

A method for assessing the cognitive and linguistic stages of second language learning in individuals is discussed. The approach is based on a psycholinguistic theory that views language learning as a process of concept formation in three domains: cognitive, cultural, and linguistic. According to the model presented, Spanish-English bilingual…

A study was conducted to test the utility of a protocol, consisting of 30 pragmatic parameters of language, to evaluate conversational speech from 157 subjects in six diagnostic groups. Four distinct profiles emerged separating the diagnostic groups within which differences in the distribution of pragmatic deficits were identified. (Author/KM)
