Clark’s model

The present study investigates teachers‘ perceptions of the values of the CEFR, the perceived readiness and necessity of its application, and the work involved in its application process. Also, it explores teachers‘ responses to the use of the CEFR to renew the general English curriculum, reflected in how they changed their teaching activities, adapted the assigned textbooks and modified their assessment practice. The study was a case study applying the mixed method sequential explanatory model (Creswell & Clark, 2007).

n recent years, renewable energy sources have greatly affected the structure and operation of power systems. Previously, grid-connected PV generators using inverters were only allowed to generate active power to ensure the utilities to adjust the voltage in the distribution grid. It is no longer optimal for system power transmission and system stability, especially when solar power sources with a capacity of hundreds of MWs having a role in regulating grid voltage. Accordingly, this paper proposes a smart inverter model of a gridconnected PV system that can regulate the reactive power.

It is expected that the upcoming DVB-NGH (Digital Video Broadcasting-Next Generation Handheld) shall be based on the existing DVB-T2 technology. Also DVB-NGH enabled Handheld receivers are going to work with the existing DVB infrastructure. In this paper we model the link budget deficits of the Handheld DVB receivers as additional power losses for a typical fixed roof-top DVB-T2 receiver. Because of those additional losses Handhelds get a reduced coverage. The attrition in coverage is especially dramatic for the indoor Handheld receivers.

This paper presents the ways of quantification of flow time qualifications that can be used for planning or other stochastic processes by employing Clark’s methods, central limit theorem and Monte Carlo simulation. The results of theoretical researches on superponed flow time quantification for complex activities and events flow in PERT network for project management are also presented.

A fundamental problem in text generation is word ordering. Word ordering is a computationally difficult problem, which can be constrained to some extent for particular applications, for example by using synchronous grammars for statistical machine translation. There have been some recent attempts at the unconstrained problem of generating a sentence from a multi-set of input words (Wan et al., 2009; Zhang and Clark, 2011). By using CCG and learning guided search, Zhang and Clark reported the highest scores on this task.

In any technological field, both short-term and longterm research can be aided by considering where that technology might be ten, twenty, fifty years down the pike. In the field of natural language interactive systems, a 21 year vision is particularly apt to consider, since it brings us to the year 2001. One wellknown vision [I] of 2001 includes the famous computer named Hal - one offspring, so to speak, of the major theoretical and engineering breakthrough in computers that Clarke records as having occurred in the early 1980's. ...

This paper discusses the supervised learning of morphology using stochastic transducers, trained using the ExpectationMaximization (EM) algorithm. Two approaches are presented: first, using the transducers directly to model the process, and secondly using them to define a similarity measure, related to the Fisher kernel method (Jaakkola and Haussler, 1998), and then using a Memory-Based Learning (MBL) technique. These are evaluated and compared on data sets from English, German, Slovene and Arabic. ...

The model used by the CCG parser of Hockenmaier and Steedman (2002b) would fail to capture the correct bilexical dependencies in a language with freer word order, such as Dutch. This paper argues that probabilistic parsers should therefore model the dependencies in the predicate-argument structure, as in the model of Clark et al. (2002), and defines a generative model for CCG derivations that captures these dependencies, including bounded and unbounded long-range dependencies.

This paper describes and evaluates log-linear parsing models for Combinatory Categorial Grammar (CCG). A parallel implementation of the L - BFGS optimisation algorithm is described, which runs on a Beowulf cluster allowing the complete Penn Treebank to be used for estimation. We also develop a new efficient parsing algorithm for CCG which maximises expected recall of dependencies. We compare models which use all CCG derivations, including nonstandard derivations, with normal-form models.

The statistical modelling of language, together with advances in wide-coverage grammar development, have led to high levels of robustness and efficiency in NLP systems and made linguistically motivated large-scale language processing a possibility (Matsuzaki et al., 2007; Kaplan et al., 2004). This paper describes an NLP system which is based on syntactic and semantic formalisms from theoretical linguistics, and which we have used to analyse the entire Gigaword corpus (1 billion words) in less than 5 days using only 18 processors. ...

Standard approaches to Chinese word segmentation treat the problem as a tagging task, assigning labels to the characters in the sequence indicating whether the character marks a word boundary. Discriminatively trained models based on local character features are used to make the tagging decisions, with Viterbi decoding finding the highest scoring segmentation. In this paper we propose an alternative, word-based segmentor, which uses features based on complete words and word sequences.

Dency parsing. We believe that our formulations can pave the way for efficient exploitation of global features and constraints in parsing applications, leading to more powerful models. Riedel and Clarke (2006) cast dependency parsing as an ILP, but efficient formulations remain an open problem.
