The goal of this study is to improve corpus-based Japanese morphological analysis which is composed by word segmentation and part-of-speech (below POS) tagging. We divide the problem of Japanese morphological analysis into three subproblems: models for known word, models for unknown word and corpus maintenance schema. Firstly, we discuss Markov model-based approaches for known word processing. ...

In this paper, we address the problem of the morphological analysis of an Arabic dialect. We propose a method to adapt an Arabic morphological analyzer for the Tunisian dialect (TD). In order to do that, we create a lexicon for the TD. The creation of the lexicon is done in two steps. The first step consists in adapting a Modern Standard Arabic (MSA) lexicon. We adapted a list of MSA derivation...

1 I n t r o d u c t i o n The two-level model of computational morphology was proposed by Koskenniemi (1983) and has found widespread acceptance due mostly to its general applicability, declarativeness of rules and clear separation of linguistic knowledge and program. The essential difference from generative phonology is that there are no intermediate states between lexical and surface represen...

Implementations of models of morphologically rich languages such as Arabic typically achieve speed and small memory footprint at the cost of abandoning linguistically abstract and elegant representations. We present a solution to modeling rich morphologies that is both fast and based on linguistically rich representations. In our approach, we convert a linguistically complex and abstract implem...

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 re...

Since 1972 a researcher team in Bonn has been working on the automatic syntax-analysis of the german language. The morphoJogical analysis is a part of this work that has already been formalized and programmed by the author. We can consider the following paper as a generalization of this formalized description. In this first chapter some expressions like " t e x t " or "lexicon " are considered ...

In a recent paper, a method called MCA (Morphological Component Analysis) has been proposed to separate the texture from the natural parts in images. MCA relies on an iterative thresholding algorithm, using a threshold which decreases linearly towards zero along the iterations. This paper shows how the MCA convergence can be drastically improved using the mutual incoherence of the dictionaries ...

Morphological analysis is a method for rigorously structuring and investigating the total set of relationships in inherently non-quantifiable socio-technical problem complexes (variously called “wicked problems” and “social messes”). The method is carried out by developing a discrete parameter space of the problem complex to be investigated, and defining relationships between the parameters on ...

The morphology of glacial valley can be described in terms of power law or quadratic equations fitted to valley cross-profiles. These two models are used to study the cross-profiles of 86 valley cross-profiles in the Zardkuh Mountain in order to understand the evolutional patterns of valleys. Assessment of using the power law function indicates that b values for both valley sides range from 1.0...
