An Ambiguity Aware Treebank Search Tool
We present a search tool for constituency treebanks with some interesting new features. The tool has been designed for a treebank containing several alternative trees for any given sentence, with one tree marked as the correct one. The tool allows to compare the selected tree with other candidates. The query language is modelled after TIGER Search, but we extend the use of the negation operator...
متن کاملThe Volume of the GPS Ambiguity Search Space and its Relevance for Integer Ambiguity Resolution
In the theory of integer least-squares ambiguity estimation and validation, a central role is played by the ambiguity search space. In this contribution, the significance of the volume of the ambiguity search space is discussed and analyzed. It is shown how the volume can be used as an estimate for the number of grid points inside the GPS ambiguity search space. This is done for various measure...
متن کاملEvaluation of the Regularization Algorithm to Decorrelation of Covariance Matrix of Float Ambiguity in Fast Resolution of GPS Ambiguity Parameters
Precise positioning in Real Time Kinematic (RTK) applications depends on the accurate resolution of the phase ambiguities. In RTK positioning, ambiguity parameters are highly correlated, especially when the positioning rate is high. Consequently, application of de-correlation techniques for the accurate resolution of ambiguities is inevitable. Phase ambiguity as positioning observations by the ...
متن کاملReducing Ambiguity in Tagging Systems with Folksonomy Search Expansion
Search facilities are vital for folksonomy (or social tagging mechanism) based systems. Although these systems allow great malleability and adaptability, they also surfer from problems, such as ambiguity in the meaning of tags, flat organisation of tags and some degree of unstabilising factor on consensus about which tags best describe some certain Web resources. It has been argued that folkson...
متن کاملSearch-Based Ambiguity Detection in Context-Free Grammars
Context Free Grammars (CFGs) can be ambiguous, allowing inputs to be parsed in more than one way, something that is undesirable for uses such as programming languages. However, statically detecting ambiguity is undecidable. Though approximation techniques have had some success in uncovering ambiguity, they can struggle when the ambiguous subset of the grammar is large. In this paper, we describ...
