Principle-Based Parsing

During the past few years, there has been much discussion of a shift from rule-based systems to principle-based systems for natural language processing. This paper outlines the major computational advantages of principle-based parsing, its differences from the usual rule-based approach, and surveys several existing principle-based parsing systems used for handling languages as diverse as Warlpiri, English, and Spanish, as well as language translation.

UNITRAN: A Principle-Based Approach to Machine Translation

Machine translation has been a particularly difficult problem in the area of Natural Language Processing for over two decades. Early approaches to translation failed since interaction effects of complex phenomena in part made translation appear to be unmanageable. Later approaches to the problem have succeeded (although only bilingually), but are based on many language-specific rules of a context-free nature. This report presents an alternative approach to natural language translation that relies on principle-based descriptions of grammar rather than rule-oriented descriptions. The model that has been constructed is based on abstract principles as developed by Chomsky (1981) and several other researchers working within the "Government and Binding" (GB) framework. Thus, the grammar is viewed as a modular system of principles rather than a large set of ad hoc language-specific rules.

The single principle of compositional data analysis, continuing fallacies, confusions and misunderstandings and some suggested remedies

In any discipline, where uncertainty and variability are present, it is important to have principles which are accepted as inviolate and which should therefore drive statistical modelling, statistical analysis of data and any inferences from such an analysis. Despite the fact that two such principles have existed over the last two decades and from these a sensible, meaningful methodology has been developed for the statistical analysis of compositional data, the application of inappropriate and/or meaningless methods persists in many areas of application. This paper identifies at least ten common fallacies and confusions in compositional data analysis with illustrative examples and provides readers with necessary, and hopefully sufficient, arguments to persuade the culprits why and how they should amend their ways

The “War on Terror” and the Principle of Distinction in International Humanitarian La

Las nuevas amenazas a la seguridad que han surgido en los últimos años están poniendo seriamente en juego la importancia y la implementación del derecho internacional humanitario. Este artículo investiga el impacto de la guerra del terror en el principio de distinción en el derecho internacional humanitario. Examina, de forma específica, prácticas estatales, por ejemplo, de los Estados Unidos, que han cedido frente al surgimiento de nuevas reglas relativas al principio de distinción. Para esto, se hace un análisis de dicho principio bajo dos perspectivas: blancos concretos y captura

Equilibrium Principle in Colombian Public Contracting

Public contracting in Colombia is conflicting and inefficient. It frequently leads to damage to State property. The Colombian legal system cannot assure efficient and transparent public contracting. The cause is the institutional environment characterized by high transaction costs. Colombian law worsens the process by recognizing the principle of economic equilibrium in public contracts. This principle increasese contract incompleteness and renders impossible the use of economic incentives to control the opportunism of the economic agents. The authors present the hypothesis that the economic equilibrium principle increases the conflictive nature of public contracting. They test the hypothesis empirically. The first section of the paper presents a summary of the literature on transaction costs economics, as well as the legal literature on the historical origin and the content of the economic equilibrium principle. The second section describes the methodology of the empirical study. The third section shows the empirical evidence of the effects that the economic equilibrium principle exerts over the public contracting. The last section presents the conclusions.

Neocolonialism and international law, with specific reference to customary counterterrorism obligations and the principle of self-defence

Has international law ever, and, if it has not, can it ever, truly freed itself from the strictures of neocolonialism and the drive by a privileged elite to dominate the world scene? This article begins by inquiring into the nature of neocolonialism and, in so doing, pays particular attention to the writings of former Ghanaian President Kwame Nkrumah. It then proceeds to determine how neocolonialist designs surface in international law today by briefly looking at two aspects of international law in particular, namely customary international law, with specific reference to the counterterrorism context, and the principle of self-defence. In the final analysis, this article argues for a necessary and eternal scepticism of international law and the agendas of its privileged gatekeepers. Like classic State power, it opens itself to, and often operates as, neocolonial overreach, and to quote Nkrumah, “[t]he cajolement, the wheedlings, the seductions and the Trojan horses of neo-colonialism must be stoutly resisted, for neo-colonialism is a latter-day harpy, a monster which entices its victims with sweet music.”
