A Lexical-Semantic Approach to AVE
نویسندگان
چکیده
This paper discusses a system capable of detecting when answers for specific questions are supported by snippets, all provided by Question Answering (QA) systems. This task is known as the Answer Validation Exercise (AVE) track within the Cross– language Evaluation Forum (CLEF). The system uses a set of regular expressions in order to join the question and the answer into an affirmative sentence and afterwards applies several lexical–semantic inferences to attempt to detect whether the meaning of this sentence can be inferred by the meaning of the supporting text. Throughout the paper we present and discuss the different system components together with the results obtained. Moreover, we want to apply special emphasis to the language–independent capabilities of some of them. As a result, we are able to apply our techniques over both Spanish and English corpora.

Dynamic Categorization of Semantics of Fashion Language: A Memetic Approach
Categories are not invariant. This paper attempts to explore the dynamic nature of semantic category, in particular, that of fashion language, based on the cognitive theory of Dawkins’ memetics, a new theory of cultural evolution. Semantic attributes of linguistic memes decrease or proliferate in replication and spreading, which involves a dynamic development of semantic category. More specific...

The paper is focused on classes of lexical units which arise as a result of derivational processes – word formation and semantic transfers, acting either in isolation or together, on the basis of common semantic foundations that bind targets and sources of derivation. The lexical items which constitute the classes under study vary in their denotative characteristics and due to their categ...

Objective: Brain trauma evidences suggest that the two grammatical categories of noun and verb are processed in different regions of the brain due to differences in the complexity of grammatical and semantic information processing. Studies have shown that the verbs belonging to different semantic categories lead to neural activity in different areas of the brain, and action verb processing is r...
متن کاملPreferred Lexical Access Route in Persian Learners of English: Associative, Semantic or Both
Background: Words in the Mental Lexicon (ML) construct semantic field through associative and/ or semantic connections, with a pervasive native speaker preference for the former. Non-native preferences, however, demand further inquiry. Previous studies have revealed inconsistent Lexical Access (LA) patterns due to the limitations in the methodology and response categorization. Objectives: To f...
