Statistical n-gram taggers like that of [Church 1988] or [Foster 1991] assign a part-ofspeech label to each word in a text on the basis of probability estimates that are automatically derived from a large, already tagged training corpus. This paper examines the grammatical constructions which cause such taggers to falter most frequently. As one would expect, certain of these errors are due to l...

Abstract We investigate the different interpretations related to metaphorical imprint of climate change in English and French media discourses. This cross-linguistic perspective is motivated by particularities both languages which have been assumed promote understandings change-related concepts. focus on metaphor carbon footprint whose meaning can be compared another English: fingerprint . Thes...

In this paper we adopt a usage-based perspective on the process of first language acquisition. Following Tomasello (2003), we assume that children initially learn concrete chunks of language, linguistic gestalts that can take different sizes and shapes, in dialogue. They then generalize across those various elements in order to assemble more abstract constructions (Fillmore 1988, Goldberg 1995)...

in this paper, two inverse problems of stephen kind with local (dirichlet) boundary conditions are investigated. in the first problem only a part of boundary is unknown and in the second problem, the whole of boundary is unknown. for the both of problems, at first, analytic expressions for unknown boundary are presented, then by using these analytic expressions for unknown boundaries and bounda...

Two experiments investigated categorical perception (CP) effects for affective facial expressions and linguistic facial expressions from American Sign Language (ASL) for Deaf native signers and hearing non-signers. Facial expressions were presented in isolation (Experiment 1) or in an ASL verb context (Experiment 2). Participants performed ABX discrimination and identification tasks on morphed ...

The number of documents available in electronic format has grown dramatically in recent years, whilst the information that governments provide to the IAEA is not always complete or clear. Independent information sources can balance the limited government-reported information, particularly if related to noncooperative targets. The process of accessing all these raw data, heterogeneous in terms o...

The flow of natural language is often broken by constructions which are difficult to analyze with conventional linguistic parsers. To handle these constructions, which include numbers, dates, addresses, etc., and, to a lesser extent, proper nouns, NL systems typically implement specialized new rules. This leads to a level of complexity which renders maintenance or improvement difficult. Analyzi...
