A system for recognition and morphological classification of unknown words for German is described and evaluated. It takes raw text as input and outputs a list of the unknown nouns together with a hypothesis about their possible morphological class and stem. MorphoClass exploits global information (ending-guessing rules, maximum likelihood estimations, word frequency statistics), morphological ...

The connection between part-of-speech (POS) categories and morphological properties is well-documented in linguistics but underutilized in text processing systems. This paper proposes a novel model for morphological segmentation that is driven by this connection. Our model learns that words with common affixes are likely to be in the same syntactic category and uses learned syntactic categories...

The chemical properties and fiber morphology of Fargesia fungosa at different culm ages and height portions were investigated. The variations in moisture, ash, SiO2, and toluene–alcohol extractive contents with culm ages were greater than they were with heights. The holocellulose varied neither significantly with age nor with height. The fiber length, width, length-to-width ratio, and wall thic...

Aims. We investigate the spatial distribution of the physical and chemical properties of the hot X-ray emitting plasma of the supernova remnant IC 443, in order to get important constraints on its ionization stage, on the progenitor supernova explosion, on the age of the remnant, and its physical association with a close pulsar wind nebula. Methods. We present XMM-Newton images of IC 443, media...

The chemical evolution history of a galaxy hides clues about how it formed and has been changing through time. We have studied the chemical evolution history of the Milky Way (MW) and Andromeda (M31) to find which are common features in the chemical evolution of disc galaxies as well as which are galaxy-dependent. We use a semi-analytic multi-zone chemical evolution model. Such models have succ...

Three SNC meteorites ranging in age from 4.5 Ga. to 1.3 Ga. to 165 m.y. contain features suggestive of past biogenic activity on Mars [1,2]. Because we do not know what past martian life looks like or its physical or chemical properties, the only tools or criteria which the scientific community have to evaluate evidence of past life is to use evidence for early life on earth. There are features...

A set of polymers was imprinted with (-)-ephedrine using UV initiation, under the influence of a constant external magnetic with intensities ranging from 0 to 1.55T. It was shown that polymer morphology and recognition properties are affected by the magnetic field leading to considerable improvements in the performance of newly synthesised materials. Apparently the magnetic field improved the o...

Satellite-derived thermal information over urban areas offers and attractive and inexpensive method which have been utilized in diverse studies including land cover classification, energy flux interactions, and as input for models of urban surface atmosphere exchange. In this study, we utilize Landsat ETM+ imagery to analyze the dependence of energy fluxes on the urban surface properties in Yor...

Morphological analysis is the basic process for any Natural Language Processing task. Morphology is the study of internal structure of the word. Morphological analysis retrieves the grammatical features and properties of a morphologically inflected word. Capturing the agglutinative structure of Tamil words by an automatic system is a challenging job. Generally rule based approaches are used for...
