This paper presents a simple but effective approach to unknown word processing in Japanese morphological analysis, which handles 1) unknown words that are derived from words in a pre-defined lexicon and 2) unknown onomatopoeias. Our approach leverages derivation rules and onomatopoeia patterns, and correctly recognizes certain types of unknown words. Experiments revealed that our approach recog...

The paper provides an Optimality Theoretic account to Modern Hebrew nonconcatenative morphology. It argues that the base of derivation is the word/stem, modified by constraints assigning the prosodic structure, the vocalic pattern, and the affixes (if any). The notion of the binyan is viewed as a configuration of the structures assigned by these constraints. The consonantal root is entirely eli...

We describe a computational framework for a grammar architecture in which different linguistic domains such as morphology, syntax, and semantics are treated not as separate components but compositional domains. Word and phrase formation are modeled as uniform processes contributing to the derivation of the semantic form. The morpheme, as well as the lexeme, has lexical representation in the for...

This paper describes the process of building Czech wordnet. We give the enumeration of the resources and tools used for this purpose and characterize so far obtained results. There are some problems with Czech as a synthetic language, with its rich inflectional morphology and word derivation. They are mentioned below and some solutions are suggested. The necessary resources for building Czech w...

We describe the design and creation of prosodic speech databases for 6 languages. The purpose of the databases is to allow derivation of prosody models in order to improve TTS synthesis. The main prosodic variables to model were word prominence, prosodic boundary strength and phone duration. We describe the database structure and contents and the methodology for creating prosodic databases, and...

The Arabic language has far richer systems of inflection and derivation than English which has very little morphology. This morphology difference causes a large gap between the vocabulary sizes in any given parallel training corpus. Segmentation of inflected Arabic words is a way to smooth its highly morphological nature. In this paper, we describe some statistically and linguistically motivate...

Briefly, a feather is a semigroup derivation diagram with the labels on the edges removed. In this paper, we are concerned with possible definitions for the thickness of a feather. A major open problem is whether the word problem is solvable for semigroup presentations with one defining relation. It is known that word problems for semigroup presentations are solvable if the number of regions in...

Let sμ denote a Schur symmetric function and Qα a fundamental quasisymmetric function. Explicit combinatorial formulas are developed for the fundamental quasisymmetric expansions of the plethysms sμ[sν ] and sμ[Qα], as well as for related plethysms defined by inequality conditions. The key tools for obtaining these expansions are new standardization and reading word constructions for matrices. ...

This article is a comparison of methods that may be used to derive texts to be typeset by a word processor. By ‘derive’, we mean that such texts are extracted from a larger structure, which can be viewed as a database. The present standard for such a structure uses an XML-like format, and we give an overview of the available tools for this derivation task.
