Dependency relations between words are increasingly recognized as an important level of linguistic representation that is close to the data and at the same time to the semantic functor-argument structure as a target of syntactic analysis and processing. Correspondingly, dependency structures play an important role in parser evaluation and for the training and evaluation of tools based on depend...

The last few years have seen a surge in the number of accurate, fast, publicly available dependency parsers. At the same time, the use of dependency parsing in NLP applications has increased. It can be difficult for a non-expert to select a good “off-the-shelf” parser. We present a comparative analysis of ten leading statistical dependency parsers on a multi-genre corpus of English. For our ana...

Context: The dependencies between individual requirements have an important influence on software engineering activities e.g., project planning, architecture design, and change impact analysis. Although dozens of requirement dependency types were suggested in the literature from different points of interest, there still lacks an evaluation of the applicability of these dependency types in requi...

Derivations under different grammar formalisms allow extraction of various dependency structures. Particularly, bilexical deep dependency structures beyond surface tree representation can be derived from linguistic analysis grounded by CCG, LFG, and HPSG. Traditionally, these dependency structures are obtained as a by-product of grammar-guided parsers. In this article, we study the alternative ...

This study presents a quantitative approach for dependency analysis of Component Based Software (CBS) systems. Various types of dependency, in a C BS, have been observed through ‘assumptions’ and based on these observations some derived dependency relationships are proposed. The proposed dependency relationships are validated theoretically and an example illustration has been shown to demonstra...

The existence of functional dependency among the state variables of a state transition system was identified as a common cause of inefficient BDD representation in formal verification. Eliminating such dependency from the system compacts the state space and may significantly reduce the verification cost. Despite the importance, how to detect functional dependency without or before knowing the r...
