this study examined the phonetic characteristics of persian sentence stress produced by native mandarin chinese speakers. we compared the phonetic correlates of sentence stress, namely fundamental frequency (f0), vowel duration, and vowel intensity in the production of 8 mandarin chinese speakers and 8 native persian speakers. results indicated that mandarin chinese speakers of persian could di...

This paper describes the National Research Council of Canada's submission to the 2011 i2b2 NLP challenge on the detection of emotions in suicide notes. In this task, each sentence of a suicide note is annotated with zero or more emotions, making it a multi-label sentence classification task. We employ two distinct large-margin models capable of handling multiple labels. The first uses one class...

A novel approach to sentence generation – SegSim, Sentence Generation by Similarity Matching – is outlined, and is argued to possess a number of desirable properties making it plausible as a model of sentence generation in the human brain, and useful as a guide for creating sentence generation components within artificial brains. The crux of the approach is to do as much as possible via similar...

Recent years have marked the beginning and rapid expansion of the social web, where people can freely express their opinion on different objects such as products, persons, topics etc on blogs, forums or e-commerce sites and opinion analysis is one emerging research field. As e-commerce is fast growing, product reviews on the Web have become an important information source for customers’ decisio...

Recent developments in question-answering systems have demonstrated that approaches based on propositional analysis of source text, in conjunction with formal inference systems, can produce substantive improvements in performance over surface-form approaches.

This paper describes the input specification language of the WAG Sentence Generation system. The input is described in terms of Halliday's (1978) three meaning components, ideational meaning (the propositional content to be expressed), interactional meaning (what the speaker intends the listener to do in making the utterance), and textual meaning (how the content is structured as a message, in ...

In this work we tackle the problem of sentence boundary detection applied to French as a binary classification task (”sentence boundary” or ”not sentence boundary”). We combine convolutional neural networks with subword-level information vectors, which are word embedding representations learned from Wikipedia that take advantage of the words morphology; so each word is represented as a bag of t...
