  • Most previous studies of morphological disambiguation and dependency parsing have been pursued independently. Morphological taggers operate on n-grams and do not take into account syntactic relations; parsers use the “pipeline” approach, assuming that morphological information has been separately obtained. However, in morphologically-rich languages, there is often considerable interaction between morphology and syntax, such that neither can be disambiguated without the other.

  • A character-based measure of similarity is an important component of many natural language processing systems, including approaches to transliteration, coreference, word alignment, spelling correction, and the identification of cognates in related vocabularies. We propose an alignment-based discriminative framework for string similarity. We gather features from substring pairs consistent with a character-based alignment of the two strings.

  • We present a stochastic parsing system consisting of a Lexical-Functional Grammar (LFG), a constraint-based parser and a stochastic disambiguation model. We report on the results of applying this system to parsing the UPenn Wall Street Journal (WSJ) treebank. The model combines full and partial parsing techniques to reach full grammar coverage on unseen data. The treebank annotations are used to provide partially labeled data for discriminative statistical estimation using exponential models.

  • The risk of acquiring variant Creutzfeldt–Jakob disease is closely related to polymorphism at codon 129 of the human prion gene, because almost all variant Creutzfeldt–Jakob disease patients are Met⁄Met homozygotes. Although animal transmission experiments corroborated this seeding dis-crimination, the origin of the differential seeding efficiency of the bovine prion seed for human codon 129 polymorphism remained elusive.

  • We address the problem of learning the mapping between words and their possible pronunciations in terms of sub-word units. Most previous approaches have involved generative modeling of the distribution of pronunciations, usually trained to maximize likelihood. We propose a discriminative, feature-rich approach using large-margin learning. This approach allows us to optimize an objective closely related to a discriminative task, to incorporate a large number of complex features, and still do inference efficiently. ...

  • This paper presents a joint model for template filling, where the goal is to automatically specify the fields of target relations such as seminar announcements or corporate acquisition events. The approach models mention detection, unification and field extraction in a flexible, feature-rich model that allows for joint modeling of interdependencies at all levels and across fields.

  • We present a discriminative model that directly predicts which set of phrasal translation rules should be extracted from a sentence pair. Our model scores extraction sets: nested collections of all the overlapping phrase pairs consistent with an underlying word alignment. Extraction set models provide two principle advantages over word-factored alignment models. First, we can incorporate features on phrase pairs, in addition to word links. Second, we can optimize for an extraction-based loss function that relates directly to the end task of generating translations. ...

  • This paper proposes a novel hierarchical learning strategy to deal with the data sparseness problem in relation extraction by modeling the commonality among related classes. For each class in the hierarchy either manually predefined or automatically clustered, a linear discriminative function is determined in a topdown way using a perceptron algorithm with the lower-level weight vector derived from the upper-level weight vector.

  • This paper presents a discriminative pruning method of n-gram language model for Chinese word segmentation. To reduce the size of the language model that is used in a Chinese word segmentation system, importance of each bigram is computed in terms of discriminative pruning criterion that is related to the performance loss caused by pruning the bigram. Then we propose a step-by-step growing algorithm to build the language model of desired size.

  • For communities around the world interested in reaching a global audience with their conservation related products and stories direct mail Catalogs and their online equivalents are an obvious choice. Some recent statistics from the National Mail Order Association (NMOA) and the American Catalog Mailers Association (ACMA) show that the US catalog industry is a $400+ billion marketplace and is made up of thousands of catalogs some with huge distribution and some which appeal to a specialized niche of the consumer market.

  • Cathepsin G (CG) (EC 3.4.21.20) and chymase (EC 3.4.21.39) are two clo-sely-related chymotrypsin-like proteases that are released from cytoplasmic granules of activated mast cells and⁄or neutrophils. We investigated the potential for their substrate-binding subsites to discriminate between their substrate specificities, aiming to better understand their respective role dur-ing the progression of inflammatory diseases.

  • Many factors can influence the dynamic balance that exists between the host and the pathogen (M. tuberculosis), but the host immune response seems to be the most important. This is illustrated by the vulnerability of immune-compromised individuals to develop tuberculosis and by the age-related spectrum of disease witnessed in immune-competent children. This age-related spectrum of disease reflects the ontogeny of the host immune response towards M. tuberculosis.

  • This research provided important findings for practitioners and mental health commissioners. Other research has also highlighted that access to appropriate treatments may be less frequent for refugees. 9 The issues are manifold and most seem to be fundamentally related to a lack of mutual understanding of mental health care needs and how the services designed to meet those specific needs are organised and accessed.
