Concentration of information at dependency structure including disjunction expression
Hiroshi Sakaki · 2006
This paper aims to construct concentrated modification structure from dependency structure. At the structure, entire information of a sentence is concentrated to single node. First, the geometrical structure called dependency structure is presented with the explanation that the structure is equivalent to the F structure of LFG. A dependency structure is obtainable from a natural language sentence through the process parallel to the way obtaining F structure of LFG. To dependency structure, the generation algorithm of concentrated modification structure is applied. When the dependency structure includes disjunction generated from entailment expression, decomposition of the disjunction first applied before the generation of concentrated modification structure.
