Converting Dependency Structures to Phrase Structures
Treebanks are of two types according to their annotation schemata: phrase-structure Treebanks such as the English Penn Treebank [8] and dependency Treebanks such as the Czech dependency Treebank [6]. Long before Treebanks were developed and widely used for natural language processing, there had been much discussion of comparison between dependency grammars and context-free phrasestructure gramm...

متن کاملConverting Phrase Structures to Dependency Structures in Sanskrit
Two annotations schemes for presenting the parsed structures are prevalent viz. the constituency structure and the dependency structure. While the constituency trees mark the relations due to positions, the dependency relations mark the semantic dependencies. Free word order languages like Sanskrit pose more problems for constituency parses since the elements within a phrase are dislocated. In ...
متن کاملTracing the Cache Behaviour of Data Structures in Fortran Applications
In an application, data access can become a major performance bottleneck if the memory hierarchy of the underlying hardware architecture is not taken into account. The only way to gain deeper insight of an applications memory usage is to measure its data access behavior with hardware counters. From the programmer’s point of view such performance data (like cache misses or hits) have to be linke...
