  • An Empirical Investigation of International Consumer Market Segmentation Decisions They may also be more effective at exerting “voice” to manage agent behavior, even without the exit option that school choice policies provide (Hirschman, 1970). Finally, student composition may operate as an employment amenity for teachers and administrators, reducing the salaries that the school must pay and increasing the quality of teachers that can be hired for any fixed salary (Antos and Rosen, 1975).

  • AN EMPIRICAL INVESTIGATION OF TURNOVER INTENTIONS OF INTERNAL AUDITORS Amenities could either increase or reduce the extent of effectiveness sorting relative to this pure case, though the latter seems more likely.22 If, as the hedonics literature implies, schools are one of the more important determinants of neighborhood desirability (see, e.g., Reback, 2001;

  • The process which has resulted in this book began many decades ago when, as an undergraduate student, I found myself asking the question, ‘What did the Romans think they were doing when they created the Roman Empire?’ For many years this question lurked in the background of my thoughts as I worked on Roman history more generally and on Roman Spain in particular, not least because itwas not clear tome howsuch a questionmight be answered.What follows is, I hope, if not an answer, at least a contribution towards one.

  • We investigate the empirical behavior of ngram discounts within and across domains. When a language model is trained and evaluated on two corpora from exactly the same domain, discounts are roughly constant, matching the assumptions of modified Kneser-Ney LMs. However, when training and test corpora diverge, the empirical discount grows essentially as a linear function of the n-gram count. We adapt a Kneser-Ney language model to incorporate such growing discounts, resulting in perplexity improvements over modified Kneser-Ney and Jelinek-Mercer baselines. ...

  • Paraphrase generation is an important task that has received a great deal of interest recently. Proposed data-driven solutions to the problem have ranged from simple approaches that make minimal use of NLP tools to more complex approaches that rely on numerous language-dependent resources. Despite all of the attention, there have been very few direct empirical evaluations comparing the merits of the different approaches.

  • This paper presents empirical studies and closely corresponding theoretical models of the performance of a chart parser exhaustively parsing the Penn Treebank with the Treebank’s own CFG grammar. We show how performance is dramatically affected by rule representation and tree transformations, but little by top-down vs. bottom-up strategies.

  • We present an empirical study of the applicability of Probabilistic Lexicalized Tree Insertion Grammars (PLTIG), a lexicalized counterpart to Probabilistic Context-Free Grammars (PCFG), to problems in stochastic naturallanguage processing. Comparing the performance of PLTIGs with non-hierarchical N-gram models and PCFGs, we show that PLTIG combines the best aspects of both, with language modeling capability comparable to N-grams, and improved parsing performance over its nonlexicalized counterpart. Furthermore, training of PLTIGs displays faster convergence than PCFGs. ...

  • In this paper, we describe an empirical study of Chinese chunking on a corpus, which is extracted from UPENN Chinese Treebank-4 (CTB4). First, we compare the performance of the state-of-the-art machine learning models. Then we propose two approaches in order to improve the performance of Chinese chunking. 1) We propose an approach to resolve the special problems of Chinese chunking. This approach extends the chunk tags for every problem by a tag-extension function. 2) We propose two novel voting methods based on the characteristics of chunking task.

  • In this paper we present a new approach to controlling the behaviour of a natural language generation system by correlating internal decisions taken during free generation of a wide range of texts with the surface stylistic characteristics of the resulting outputs, and using the correlation to control the generator. This contrasts with the generate-andtest architecture adopted by most previous empirically-based generation approaches, offering a more efficient, generic and holistic method of generator control. ...

  • This paper presents a status quo of an ongoing research study of collocations – an essential linguistic phenomenon having a wide spectrum of applications in the field of natural language processing. The core of the work is an empirical evaluation of a comprehensive list of automatic collocation extraction methods using precision-recall measures and a proposal of a new approach integrating multiple basic methods and statistical classification.

  • This paper describes an empirical study of the “Information Synthesis” task, defined as the process of (given a complex information need) extracting, organizing and inter-relating the pieces of information contained in a set of relevant documents, in order to obtain a comprehensive, non redundant report that satisfies the information need.

  • The processes through which readers evoke mental representations of phonological forms from print constitute a hotly debated and controversial issue in current psycholinguistics. In this paper we present a computational analysis of the grapho-phonological system of written French, and an empirical validation of some of the obtained descriptive statistics.

  • We refine and extend prior views of the description, purposes, and contexts-of-use of acknowledgment acts through empirical examination of the use of acknowledgments in task-based conversation. We distinguish three broad classes of acknowledgments (other--*ackn, self--*other--*ackn, and self+ackn) and present a catalogue of 13 patterns within these classes that account for the specific uses of acknowledgment in the corpus.

  • The tales here told are written, not to glorify war, but to nourish patriotism. They represent an effort to renew in popular memory the great traditions of the Imperial race to which we belong. The history of the Empire of which we are subjects--the story of the struggles and sufferings by which it has been built up--is the best legacy which the past has bequeathed to us. But it is a treasure strangely neglected. The State makes primary education its anxious care, yet it does not make its own history a vital part of that education. There is real danger that for the average youth...

  • In the connection of the church and state, I have considered the former as subservient only, and relative, to the latter; a salutary maxim, if in fact, as well as in narrative, it had ever been held sacred. The Oriental philosophy of the Gnostics, the dark abyss of predestination and grace, and the strange transformation of the Eucharist from the sign to the substance of Christ's body, ^1 I have purposely abandoned to the curiosity of speculative divines.

  • Stealing Empire poses the question, "What possibilities for agency exist in the age of corporate globalisation?" Using the work of Antonio Negri and Michael Hardt as a point of entry, Adam Haupt delves into varied terrain to locate answers in this ground-breaking inquiry. He explores arguments about copyright via peer-to-peer (P2P) platforms such as Napster, free speech struggles, debates about access to information and open content licenses, and develops a politically incisive analysis of counterdiscourses produced by South African hip-hop artists.
