Dependency structures do not have the information of phrase categories in phrase structure grammar. Thus, dependency parsing relies heavily on the lexical information of words. This paper discusses our investigation into the effectiveness of lexicalization in dependency parsing. Specifically, by restricting the degree of lexicalization in the training phase of a parser, we examine the change in...

Word-finding difficulty (anomia) is the most common linguistic deficit in dementia. It is often measured by picture naming tasks as naming a picture taps all the major processes in word production, i.e., activation of a concept, retrieval of lexical-semantic information on that concept, retrieval of the corresponding word form and articulation. Naming and naming errors have extensively been sim...

 Lexicalization-patterns, the way words are mapped onto concepts, differ from one language      to another. This study investigated the influence of first language (L1) lexicalization patterns on the processing of second language (L2) words in sentential contexts by both less proficient and more proficient Persian learners of English. The focus was on cases where two different senses of a polys...

The online era has made available almost cosmic amounts of information in the public and semi-restricted domains, prompting development of corresponding host of technologies to organize and navigate this information. One of these developing technologies deals with encoding information from free form natural language into a structured form as RDF triples. This representation enables machine proc...

Languages vary in how they encode motion events. For example, English motion verbs often encode the manner of the motion while Spanish motion verbs encode the path. Efficient verb learning has been argued to involve the acquisition of language specific lexicalization biases. When given a novel verb paired with a single motion event, English speakers interpret it as a manner verb, Spanish speake...

Some metaphorical mappings between source and target are obvious and appear in collocation patterns in natural language data. However, other metaphors that structure abstract processes or complex topics are trickier to investigate because the target domain is lexically divorced from the source. Using metaphors for the economy as a case study, this paper introduces new techniques to find metapho...

Learning a new word involves integration with existing lexical knowledge. Previous work has shown that sleepdependent memory consolidation processes are important for the engagement of novel items in lexical competition. We used spaced learning and testing to investigate memory for novel words and their lexicalization across the course of a single day, compared with a day later. We expected tha...
