X2MORF 1 is a language independent morphological component for the recognition and generation of word forms based on a lexicon of morphs. The approach is based on two-level morphology. Extensions are motivated by linguistic data which call into question an underlying assumption of standard two-level morphology, namely the independence of morphophonology and morphology as exemplified by two-leve...

A method is described to automatically acquire from text corpora a Portuguese stem lexicon for two-level morphological analysis. It makes use of a lexical transducer to generate all possible stems for a given unknown inflected word form, and the EM algorithm to rank alternative stems. 1 M o t i v a t i o n Morphological analysis is the basis for most natural language processing tasks. Hand-code...

The typical equation for bed level change in sediment transport in river, estuary and near shore systems is based on conservation of sediment mass. It is generally a nonlinear conservation equation for bed level. The physics here are similar to shallow water wave equations and gas dynamics equation which will develop shock waves in many circumstances. Many state-of-art morphological models use ...

The focus of recent studies on Chinese word segmentation, part-of-speech (POS) tagging and parsing has been shifting from words to characters. However, existing methods have not yet fully utilized the potentials of Chinese characters. In this paper, we investigate the usefulness of character-level part-of-speech in the task of Chinese morphological analysis. We propose the first tagset designed...

With the aim of determining the common morphological features of senior male handball players and of analyzing their specificities i.e. the probable variation between the four playing positions (back court players, wings, pivots, goalkeepers), 25 anthropometric measures were applied to the sample of 49 players, members of three top-quality handball teams. The basic descriptive parameters were c...

Phyllostomidae (New World leaf-nosed bats), the second most speciose chiropteran family, is one of the best-known and wellstudied chiropteran groups. Due to the ecological and morphological diversity of this family, comparative studies of phyllostomids abound in the literature, and numerous systematic and phylogenetic analyses have been published. Unfortunately, many of these studies have reach...

We propose a novel level set method for fast image segmentation, which evolves level set functions using simple binary morphological operations. The proposed method is superior to a previously reported morphological level set method in capable of bidirectional evolution of level set functions, i.e., the interface of a level set function can either expand or shrink toward the object boundary. Th...

The present paper focuses on representation of morphological meanings on the underlying syntactic level. The concept of semantic counterparts of morphological meanings, the so-called grammatemes, was introduced in Functional Generative Description in the 1960’s. We suggest an elaborated system of these grammatemes, which have become a part of the tectogrammatical level of the Prague Dependency ...

A high-level language lor the description of inflectional morphology is presented, in which the organization of word lormation rules into an ii~herilance hierarchy of paradigms allows l o r a natural encoding of the kinds of nfles typically pre~uted in grammar txroks. We show how tim language, composed of orthographic rides, word formation rules, and paradigm inheritance, can be compiled into a...
