Word sense discrimination is to group occurrences of a word into clusters based on unsupervised classification method, where each cluster consists of occurrences having same meaning. Feature extraction method has been used to reduce the dimension of context vector in English word sense discrimination task. But if original dimension has a real meaning to users and relevant features exist in orig...

Manually annotated data is expensive, so manually covering a large terminological resource like the UMLS Metathesaurus is infeasible. In this paper, we evaluate two approaches used to improve the quality of an automatically extracted corpus to train statistical learners to performWSD. The first one contributes to more specific terms while the second filters out false positives. Using both appro...

Social discrimination is considered illegal and unethical in the modern world. Such discrimination is often implicit in observed decisions’ datasets, and anti-discrimination organizations seek to discover cases of discrimination and to understand the reasons behind them. Previous work in this direction adopted simple observational data analysis; however, this can produce biased results due to t...

Research on the development of speech processing in bilingual children has typically implemented a cross-sectional design and relied on behavioral measures. The present study is the first to explore brain measures within a longitudinal study of this population. We report results from the first phase of data analysis in a longitudinal study exploring Spanish-English bilingual children and the re...

Quality and rate of preserved hearing are crucial to make hearing preservation surgery a viable treatment. A long-term experience with hearing preservation surgery, with tumour size and hearing as admission criteria, was evaluated to assess which size and hearing allowed a high rate of success. The hearing outcome in relation to size of tumour and pre-operative hearing was retrospectively revie...

background: according to previous studies, most of the speech recognition disorders in older adults are the results of deficits in audibility and auditory temporal resolution. in this paper, the effect of ageing on timecompressed speech and auditory temporal resolution by word recognition in continuous and interrupted noise was studied. methods: a time-compressed speech test (tcst) was conducte...

Background: Speech perception ability depends on auditory and extra-auditory elements. The signal-to-noise ratio (SNR) is an extra-auditory element that has an effect on the ability to normally follow speech and maintain a conversation. Speech in noise perception difficulty is a common complaint of the elderly. In this study, the importance of SNR magnitude as an extra-auditory effect on speech...
