  • The purpose of this book is to examine the experience of a number of countries in grappling with the problems of reconciling the two fields of competition policy and intellectual property rights. The first two parts of the book indicate the variation in legislative models as well as the wide variety of judicial and administrative doctrines that have been used. The jurisdictions selected for study are the three major trading blocks with the longest experience of case law, the EU, the USA and Japan, and three less populous countries with open economies, Australia, Ireland and Singapore.

  • This book is about pricing issues in modern communications networks. Recent technology advances, combined with the deregulation of the communication market and the proliferation of the Internet, have created a new and highly competitive environment for communication service providers. Both technology and economics play a major role in this new environment. As recent events in the marketplace make clear, the success of a communication services business is not guaranteed by new technology alone.

  • We model the impact of bank mergers on loan competition, reserve holdings, and aggregate liquidity. A merger changes the distribution of liquidity shocks and creates an internal money market, leading to financial cost efficiencies and more precise estimates of liquidity needs. The merged banks may increase their reserve holdings through an internalization effect or decrease them because of a diversification effect. The merger also affects loan market competition, which in turn modifies the distribution of bank sizes and aggregate liquidity needs.

  • Competition in Product Variety: Theory and Evidence I begin by describing the allocation of effectiveness in illustrative equilibria, then describe the simulation and its results. Finally, at the end of this section I return to the basic model to discuss its allocative implications and the likely effects of endogenizing school effectiveness.

  • INFORMATION SYSTEM QUALITY : AN EXAMINATION OF SERVICE-BASED MODELS AND ALTERNATIVES If both peer group and school effectiveness are important to parents, then, the Tiebout mechanism rewards effective administrators only when there are many districts. Model (3) suggests that in this case the test score gap between high- and low-income schools will tend to be larger in markets with a great deal of interdistrict competition than in those with less Tiebout choice. I test for this in the empirical analysis below....

  • This paper describes an unsupervised dynamic graphical model for morphological segmentation and bilingual morpheme alignment for statistical machine translation. The model extends Hidden Semi-Markov chain models by using factored output nodes and special structures for its conditional probability distributions. It relies on morpho-syntactic and lexical source-side information (part-of-speech, morphological segmentation) while learning a morpheme segmentation over the target language. Our model outperforms a competitive word alignment system in alignment quality. ...

  • Clearly, man-made projects are not new: monuments surviving from the earliest civilizations testify to the incredible achievements of our forebears and still evoke our wonder and admiration. Modern projects, for all their technological sophistication, are not necessarily greater in scale than some of those early mammoth works.

  • This paper describes the application of so-called topic models to selectional preference induction. Three models related to Latent Dirichlet Allocation, a proven method for modelling document-word cooccurrences, are presented and evaluated on datasets of human plausibility judgements. Compared to previously proposed techniques, these models perform very competitively, especially for infrequent predicate-argument combinations where they exceed the quality of Web-scale predictions while using relatively little data. ...

  • We present an unsupervised model for joint phrase alignment and extraction using nonparametric Bayesian methods and inversion transduction grammars (ITGs). The key contribution is that phrases of many granularities are included directly in the model through the use of a novel formulation that memorizes phrases generated not only by terminal, but also non-terminal symbols. This allows for a completely probabilistic model that is able to create a phrase table that achieves competitive accuracy on phrase-based machine translation tasks directly from unaligned sentence pairs. ...

  • In this paper we propose a competition learning approach to coreference resolution. Traditionally, supervised machine learning approaches adopt the singlecandidate model. Nevertheless the preference relationship between the antecedent candidates cannot be determined accurately in this model. By contrast, our approach adopts a twin-candidate learning model. Such a model can present the competition criterion for antecedent candidates reliably, and ensure that the most preferred candidate is selected.

  • Update summarization is a new challenge in multi-document summarization focusing on summarizing a set of recent documents relatively to another set of earlier documents. We present an unsupervised probabilistic approach to model novelty in a document collection and apply it to the generation of update summaries. The new model, called D UAL S UM, results in the second or third position in terms of the ROUGE metrics when tuned for previous TAC competitions and tested on TAC-2011, being statistically indistinguishable from the winning system.

  • We consider the search for a maximum likelihood assignment of hidden derivations and grammar weights for a probabilistic context-free grammar, the problem approximately solved by “Viterbi training.” We show that solving and even approximating Viterbi training for PCFGs is NP-hard. We motivate the use of uniformat-random initialization for Viterbi EM as an optimal initializer in absence of further information about the correct model parameters, providing an approximate bound on the log-likelihood.

  • 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.

  • Extracting semantic relationships between entities is challenging because of a paucity of annotated data and the errors induced by entity detection modules. We employ Maximum Entropy models to combine diverse lexical, syntactic and semantic features derived from the text. Our system obtained competitive results in the Automatic Content Extraction (ACE) evaluation. Here we present our general approach and describe our ACE results.

  • This paper presents a massively parallel parser that predicts critical attachment behaviors of the human sentence processor, without the use of explicit preference heuristics or revision strategies. The processing of a syntactic ambiguity is modeled as an active, distributed competition among the potential attachments for a phrase. Computationally motivated constraints on the competitive mechanism provide a principled and uniform account of a range of human attachment preferences and garden path phenolnena. ...
