  • We investigate the tasks of general morphological tagging, diacritization, and lemmatization for Arabic. We show that for all tasks we consider, both modeling the lexeme explicitly, and retuning the weights of individual classifiers for the specific task, improve the performance.

  • This paper describes a method of analysing words through morphological decomposition when the lexicon is incomplete. The method is used within a text-to-speech system to help generate pronunciations of unknown words. The method is achieved within a general morphological analyser system using Koskenniemi twolevel rules.

  • This paper presents an exponential model for translation into highly inflected languages which can be scaled to very large datasets. As in other recent proposals, it predicts targetside phrases and can be conditioned on sourceside context. However, crucially for the task of modeling morphological generalizations, it estimates feature parameters from the entire training set rather than as a collection of separate classifiers.

  • To begin, at the left of the figure, trends in risk factors or biological markers such as cholesterol and other lipids, weight, and indicators of insulin regulation are separate markers of underlying health and population propensity to disease. At the population level, the age of onset of these factors generally precedes the onset of related diseases like cardiovascular disease and diabetes. The second box includes diseases, conditions, and impairments.

  • We present a general architecture for efficient and deterministic morphological analysis based on memory-based learning, and apply it to morphological analysis of Dutch. The system makes direct mappings from letters in context to rich categories that encode morphological boundaries, syntactic class labels, and spelling changes. Both precision and recall of labeled morphemes are over 84% on held-out dictionary test words and estimated to be over 93% in free text.

  • Koskenniemi's model of two-level morphology has been very influential in recent years, but definitions of the formalism have generally been phrased in terms of a compilation (sometimes left unspecified) into a form of finite-state transducers, or else have consisted of an informal outline of the intended interpretation of the rule-formalism itself. Analyses of the properties of the formalism have generally focussed on the transducer mechanism.

  • This paper describes our current research on the properties of derivational affixation in English. Our research arises from a more general research project, the Lexical Systems project at the IBM Thomas J. Watson Research laboratories, the goal for which is to build a variety of computerized dictionary systems for use both by people and by computer programs. An important sub-goal is to build reliable and robust word recognition mechanisms for these dictionaries.

  • In the last few years, so called finite.state morphology, in general, and two-level morphology in particular, have become widely accepted as paradigms for the computational treatment of morphology. Finite-state morphology appeals to the notion of a finite-state transducer, which is simply a classical finite-state automaton whose transitions are labeled with pairs, rather than with single symbols. The automaton operates on a pair of tapes and advances over a given transition if the current symbols on the tapes match the pair on the transition. ...

  • We present a notation for the declarative statement of morphological relationships and lexieal rules, based on the traditional notion of Word and Paradigm (cf Hockett 1954). The phenomenon of blocking arises from a generalized version of Kiparsky's (1973) Elsewhere Condition, stated in terms of ordering by subsumption over paradigms. Orthographic constraints on morphemic alternation are described by means of string equations (Siekmann 1975).

  • The term stress was introduced into the biomedical field by Hans Selye (1936) in reference to a General Adaptation Syndrome which would consist of all non-specific systemic reactions that occur during an intense and chronic exposure to a stressor (e.g., pressure at work and poor diet). This syndrome would be different from the specific adaptive reactions (such as muscle hypertrophy caused by exercise performed on a regular basis) and immune responses (Selye, 1936).

  • The endoplasmic reticulum (ER) and the Golgi apparatus both maintain their specific morphology, composition, and function in spite of the exchange of proteins and lipids between the two organelles through membrane trafficking. The morphology of the Golgi apparatus is closely linked to the balance between anterograde (ER-to-Golgi) and retrograde (Golgi-to-ER) transport. It has been reported that the inhibition of anterograde transport leads to the redistribution of Golgi components to the cytoplasm or the ER (Storrie et al., 1998; Ward et al., 2001; Miles et al., 2001).

  • In the last decade the progress of molecular biology has made a strong influence on the theoretical framework of population genetics and evolution. Introduction of molecular techniques in this area has resulted in many new discoveries. As a result, a new interdisciplinary science, which may be called 'Molecular Population Genetics and Evolution', has emerged. In this book I have attempted to discuss the development and outline of this science. In recent years a large number of papers have been published on this subject.

  • Virtually every organism serves as the host for a complement of parasites. Parasitism is so common that it is rare to find classes of animals without members that have adopted a parasitic mode of living. Evidence gained from various archeological studies indicates that parasitic diseases existed in prehistoric human populations. Since there is no evidence to suggest that our long and intimate association with parasites will ever end, it seems reasonable to propose that the study of human parasites warrants some consideration.

  • In general, evacuation plans are in place for all long term care settings. What varies most is how much has been actually tested, and what sectors have been involved in these drills and exercises. In many cases, the drills have been mostly simulated, the first responders and transportation mechanisms have not been adequately involved, and tracking systems and the mechanics of moving residents with documentation and medications have not been tested. Evacuation plans and drills must be taken to the next level of preparedness by involving all sectors and actually testing as much as possible....
