Recent work has challenged the previously widely accepted belief that affective processing does not require awareness and can be carried out with more limited resources than semantic processing. This debate has focused exclusively on visual perception, even though evidence from both human and animal studies suggests that existence for nonconscious affective processing would be physiologically m...

Normally, the tense and aspect systems of natural languages do not coincide and the correct translation of the tense forms needs a semantic analysis of the text or sentence which uses these forms. The problem with semantic representations is that, often, ambiguities cannot be resolved, though a remarkable effort of inferencing has been invested to the effect that the analysis of the source text...

the current article was an attempt to investigate the effect of semantic mapping strategy instruction on reading comprehension performance of efl learners. to this end, thirty homogeneous iranian intermediate efl learners attending a language school in bonab, iran, were randomly assigned to two groups, one as the experimental and the other as the control. the experimental group received instruc...

In 2 studies, we examined whether explicit distractors are necessary and sufficient to evoke selective inhibition in 3 naming tasks: the semantic blocking, picture-word interference, and color-word Stroop task. Delta plots were used to quantify the size of the interference effects as a function of reaction time (RT). Selective inhibition was operationalized as the decrease in the size of the in...

This study examined how task (implicit vs. explicit) and semantic relationship (direct vs. indirect) modulated hemodynamic activity during lexico-semantic processing. Participants viewed directly related, indirectly related, and unrelated prime-target word-pairs as they performed (a) an implicit lexical decision (LD) task in which they decided whether each target was a real word or a nonword, a...

As a microblogging service, Twitter is playing a more and more important role in our life. Users follow various accounts, such as friends or celebrities, to get the most recent information. However, as one follows more and more people, he/she may be overwhelmed by the huge amount of status updates. Twitter messages are only displayed by time recency, which means if one cannot read all messages,...

objective: the study was designed to examine explicit memory bias in trait-anxiety and obsessive compulsive disorder. method: memory bias was examined in three groups of subjects: low-trait  anxious (20 subjects), high-trait anxious (20 subjects), and obsessive compulsive patients (20 subjects) in whom danger schema were activated after they were exposed the threat-related material. the trait-a...

In this paper we present the technical details of the retrieval system with which we participated at the CLEF09 Ad-hoc TEL task. We present a retrieval approach based on multiple indexes for different languages which is combined with a conceptbased retrieval approach based on Explicit Semantic Analysis. In order to create the language-specific indices for each language, a language detection app...

In this extended abstract we describe several semantic sources that can be found in the Web that are either explicit, e.g. Wikipedia, or implicit, e.g. derived from Web data. We also show how we are using them to improve search and to generate new semantic resources, as our final goal is to produce a virtuous feedback circuit for semantic enhancement based in machine learning.
