  • We consider a semi-supervised setting for domain adaptation where only unlabeled data is available for the target domain. One way to tackle this problem is to train a generative model with latent variables on the mixture of data from the source and target domains. Such a model would cluster features in both domains and ensure that at least some of the latent variables are predictive of the label on the source domain.

  • Distributional similarity has been widely used to capture the semantic relatedness of words in many NLP tasks. However, various parameters such as similarity measures must be handtuned to make it work effectively. Instead, we propose a novel approach to synonym identification based on supervised learning and distributional features, which correspond to the commonality of individual context types shared by word pairs. Considering the integration with pattern-based features, we have built and compared five synonym classifiers. ...

  • This paper focuses on identifying, extracting and evaluating features related to syntactic complexity of spontaneous spoken responses as part of an effort to expand the current feature set of an automated speech scoring system in order to cover additional aspects considered important in the construct of communicative competence.

  • Transition-based dependency parsers generally use heuristic decoding algorithms but can accommodate arbitrarily rich feature representations. In this paper, we show that we can improve the accuracy of such parsers by considering even richer feature sets than those employed in previous systems. In the standard Penn Treebank setup, our novel features improve attachment score form 91.4% to 92.9%, giving the best results so far for transitionbased parsing and rivaling the best results overall. For the Chinese Treebank, they give a signficant improvement of the state of the art. ...

  • This paper examines how a new class of nonparametric Bayesian models can be effectively applied to an open-domain event coreference task. Designed with the purpose of clustering complex linguistic objects, these models consider a potentially infinite number of features and categorical outcomes. The evaluation performed for solving both within- and cross-document event coreference shows significant improvements of the models when compared against two baselines for this task.

  • We investigate the tasks of general morphological tagging, diacritization, and lemmatization for Arabic. We show that for all tasks we consider, both modeling the lexeme explicitly, and retuning the weights of individual classifiers for the specific task, improve the performance.

  • The algorithm is implemented on top of the Selective Gain Computation (SGC) algorithm (Zhou et al., 2003), which offers fast training and high quality models. Theoretically, the new algorithm is able to explore an unlimited amount of features. Because of the improved capability of the CME algorithm, we are able to consider many new features and feature combinations during model construction.

  • Various feature descriptions are being employed in constrained-based grammar formalisms. The common notational primitive of these descriptions are functional attributes called features. The descriptions considered in this paper are the possibly quantified first-order formulae obtained from a signature of features and sorts. We establish a complete firstorder theory F T by means of three axiom schemes and construct three elementarily equivalent models. One of the models consists of so-called feature graphs, a data structure common in computational linguistics. ...

  • Many different types of features have been shown to improve accuracy in parse reranking. A class of features that thus far has not been considered is based on a projection of the syntactic structure of a translation of the text to be parsed. The intuition for using this type of bitext projection feature is that ambiguous structures in one language often correspond to unambiguous structures in another. We show that reranking based on bitext projection features increases parsing accuracy significantly. ...

  • In order to understand and manage our air quality resources, it is necessary to gain a fundamental understanding of the principles that govern our ability to do so. From a local perspective, it may be considered desirable to install huge fans in order to “blow the smog away,” but from a technological and scientific perspective it is not feasible. Likewise, from a regional or continental perspective, it is not acceptable to merely transfer air contaminants from one location to another one by dilution or “blowing it away.”...

  • A fundamental approach in signal processing is to design a statistical generative model of the observed signals. The components in the generative model then give a representation of the data. Such a representation can then be used in such tasks as compression, denoising, and pattern recognition. This approach is also useful from a neuroscientific viewpoint, for modeling the properties of neurons in primary sensory areas. In this chapter, we consider a certain class of widely used signals, which we call natural images....

  • Considering the vital importance of writing skill in ESL studies, it is highly desirable that learners of English in our schools and colleges have the required level of proficiency in this field. However, the glaring truth is that majority of students at High School level in vernacular medium schools through out the country have a very poor proficiency level in writing. This has been studied and recorded by many research scholars from various parts of the country.

  • “Kirk told me I could buy beer at the petrol station,” was the first sentence I heard out of Ben Evans’ mouth. He had come to Crete for an Open Spaces Java conference. I explained that I usually bought petrol at the petrol station, but that there was a shop around the corner that sold beer. Ben looked disappointed. I had lived on this Greek island for five years and had never thought of trying to buy beer at the local BP. I felt a bit like this while reading this book. I consider myself a Java fundi. I have spent the past 15 years programming...

  • In a similar way, environmental considerations are frequently viewed as barriers to profitability. They are viewed as necessary evils, costs to be minimized, or regulations with which to comply. The environment is rarely considered central to business strategy unless there is some regulation that constrains business goals, a mess to clean up, or a public issue which pits executives against environmentalists. Historically, business people neither have been encouraged nor discouraged to get involved with environmental concerns.

  • Social determinants of health have a strong influence on a wide diversity of health endpoints. The same is valid for the field of environmental health, as the exposure to environmental risk factors is also unequally distributed, and this unequal distribution is often related to social characteristics such as income, social status, employment and education, but also non-economic aspects such as gender, age or ethnicity. However, depending on the environmental risk and the “risk group” considered, the magnitude of inequality varies largely.

  • If you’re an absentee landlord — or just too busy to handle maintenance — a property manager may be a good solution. This third-party manager runs the place, does the bookkeeping, scouts out the best repair people, and takes those 3 a.m. phone calls. In addition, the manager collects monthly rents and even leases the property for you. While they remove all the burdens from your shoulders, they come at a price. You can expect to pay 5% to 10% of your gross income, and even more if additional services are performed.

  • Romans held Greek civilization in high regard and, like us, considered fifth-century-BC Greece to be the region’s golden age, a time characterized by refined artistic and cultural production, scholarship, and military strength. During his reign five hundred years later, Augustus sought to align his rule with this era and promote a rebirth of the golden age of Greece in Rome. Augustus’s interest in Greek art and culture strengthened Roman reverence for classical Greek art, philosophy, and intellectual life.
