  • At least since Chomsky, the usual response to the projection problem has been to characterize knowledge of language as a grammar, and then proceed by restricting so severely the class of grammars available for acquisition that the induction task is greatly simplified - perhaps trivialized. The work reported here describes an implemented LISP program that explicitly reproduces this methodological approach to acquisitio,~ - but in a computational setting.

  • This paper presents an incremental probabilistic learner that models the acquistion of syntax and semantics from a corpus of child-directed utterances paired with possible representations of their meanings. These meaning representations approximate the contextual input available to the child; they do not specify the meanings of individual words or syntactic derivations. The learner then has to infer the meanings and syntactic properties of the words in the input along with a parsing model.

  • We present an outline of the genome information acquisition (GENIA) project for automatically extracting biochemical information from journal papers and abstracts. GENIA will be available over the Internet and is designed to aid in information extraction, retrieval and visualisation and to help reduce information overload on researchers. The vast repository of papers available online in databases such as MEDLINE is a natural environment in which to develop language engineering methods and tools and is an opportunity to show how language engineering can play a key role on the Internet. ...

  • Supervised learning methods for WSD yield better performance than unsupervised methods. Yet the availability of clean training data for the former is still a severe challenge. In this paper, we present an unsupervised bootstrapping approach for WSD which exploits huge amounts of automatically generated noisy data for training within a supervised learning framework. The method is evaluated using the 29 nouns in the English Lexical Sample task of SENSEVAL2.

  • We explore this question in two ways. First, we examine the breadth of the recent rise in sector effects, by exploring the evolution over time of country and industry effects outside of the technology, media and telecommunications (TMT) sectors. Our focus on TMT derives from the fact that these sectors have been identified in financial circles as being central to the recent stock market bubble.

  • Against this background, we make several advances over the literature. We construct a new dataset that covers virtually the entire global stock market in capitalization terms and find—for this more comprehensive dataset—that industry effects have gone from less than half as important as country effects in the mid-1990s to almost twice as important in recent years. This shift is primarily driven by a dramatic rise in magnitude of industry effects, with country effects roughly stable since the mid-1990s.

  • While the most promising findings are supposed to derive from cross-case analyses, each dis- sertation selected a specific research question related to the overall topic of the ICS project. In the first phase, all dissertations conducted an outside-in analysis of resource allocations at a selected case study company using a common methodology developed by Schmidt (2000) and further refined by the research team (Müller-Stewens and Schmidt, 2003).

  • Growing international competition means that companies are under increased pressure to uncover what others in the industry are doing. An article in the Pittsburgh Post Gazette stated that, “Managers have ignored, denied, and/or subverted the role of intelligence in creating shareholder value. Due diligence is best demonstrated when a business decision such as an acquisition has intelligence as its foundation. Utilizing the best available intelligence will not guarantee success but it will certainly help you make more value- creating rather than value-destroying decisions.” ...

  • Through years of clinical practice and teaching, I have observed that orientation to each major clinical nursing specialty usually leads the novice to ask a somewhat predictable set of questions ranging from specialty-related communication, to assessment and anatomy, physiology, and pathology involved in frequently seen conditions to questions related to the planning and implementation of patient care. Many excellent texts are available to provide in-depth information related to these topics.

  • Increased levels and volatility of food prices has led to a surge of interest in large-scale agriculture and land acquisition. This creates challenges for policy makers aiming to establish a policy environment conducive to an agrarian structure to contribute to broad-based development in the long term. Based on a historical review of episodes of growth of large farms and their impact, this paper identifies factors underlying the dominance of owner-operated farm structures and ways in which these may change with development.
