Moreover, we study how the vocabulary size reduction aff...
متن کاملInformation Retrieval and Text Categorization with Semantic Indexing
In this paper, we present the effect of the semantic indexing using WordNet senses on the Information Retrieval (IR) and Text Categorization (TC) tasks. The documents have been sense-tagged using a Word Sense Disambiguation (WSD) system based on Specialized Hidden Markov Models (SHMMs). The preliminary results showed that a small improvement of the performance was obtained only in the TC task. ...

15 صفحه اولThe N400 in a semantic categorization task across 6 decades.
OBJECTIVES To characterize the effects of normal aging on the amplitude, latency and scalp distribution of the N400 congruity effect. METHODS Event-related brain potentials (ERPs) were recorded from 72 adults (half of them men) between the ages of 20 and 80 years (12/decade) as they performed a semantic categorization task.
