After a short recall of our view of dependency grammars, we present two dependency parsers. The first uses dependency relations to have a more concise expression of dependency rules and to get efficiency in parsing. The second uses typed feature structures to add some semantic knowledge on dependency trees and parses in a more robust left to right manner.

This article presents an ensemble system for dependency parsing of Spanish that combines three machine-learning-based dependency parsers. The system operates in two stages. In the first stage, each of the three parsers analyzes an input sentence and produces a dependency graph. In the second stage, a voting system distills a final dependency graph out of the three first-stage dependency graphs.

We present a statistical post-editing method for modifying the dependency labels in a dependency analysis. We test the method using two English datasets, three parsing systems and three labelled dependency schemes. We demonstrate how it can be used both to improve dependency label accuracy in parser output and highlight problems with and differences between constituency-to-dependency conversions.

Successful ontological analysis depends upon having the right underlying theory. The work described here, exploring how to understand organisations as systems of social norms found that the familiar objectivist position did not work, eventually replacing it with a radically subjectivist ontology which treats every thing, relationship and attribute as a repertoire of behaviour as understood by s...

In Japanese, syntactic structure of a sentence is generally represented by the relationship between phrasal units, or bunsetsus in Japanese, based on a dependency grammar. In the same way, the syntactic structure of a sentence in a large, spontaneous, Japanese-speech corpus, the Corpus of Spontaneous Japanese (CSJ), is represented by dependency relationships between bunsetsus. This paper descri...

• The White House Office of National Drug Control Policy conducted a survey and found that between 1988 and 1995, Americans spent over $57 billion on illegal drugs of abuse. • The Lewin Group for the National Institute on Drug Abuse found that in 1992, the estimated total economic cost of alcohol and drug abuse was $245.7 billion. This estimate included the cost for substance abuse treatment, c...

Introduction:Stroke is the 3 cause of death and although it is a common disease,its incidence is not the same in diffirent parts of the world and depends on various factors.opium dependency apart from being a social and cultural problem has several effects on physiological,immune and coagulation systems and conseguently the risk of stroke. Method:The study was done in Kerman shafa hospital dur...

Simply typed term rewriting [Yam01] is a framework of higher-order term rewriting without bound variables. The authors extended the first-order dependency pair approach [AG00] to the case of simply typed term rewriting [AY05]. They gave a characterization of minimal non-terminating simply typed terms and incorporated the notions of dependency pairs, dependency graphs, and estimated dependency g...

Abstract Background: Opium dependency is an important health problem in Iran. Several studies show that most opium dependent patients have concomitant psychiatric disorders. The aim of this study was evaluation of psychiatric disorders in opium dependency in comparison with heroin dependency. Methods: This is a descriptive study on 192 male opium dependent patients who were admitted i...
