Hierarchical Phrase-Based Translation with Weighted Finite-State Transducers and Shallow-n Grammars
Hierarchical Phrase-Based Translation Weighted Finite-State Transducers Shallow-n Grammars
2015/9/8
In this article we describe HiFST, a lattice-based decoder for hierarchical phrase-based translation and alignment. The decoder is implemented with standard Weighted Finite-State Transducer (WFST) ope...
Weighted and Probabilistic Context-Free Grammars Are Equally Expressive
Weighted and Probabilistic Context-Free Grammars Equally Expressive
2015/9/2
This article studies the relationship between weighted context-free grammars (WCFGs), where each production is associated with a positive real-valued weight, and probabilistic context-free grammars (P...
Weighted Deductive Parsing and Knuth's Algorithm
Weighted Deductive Parsing Knuth's Algorithm
2015/8/28
We discuss weighted deductive parsing and consider the problem of finding the derivation with the lowest weight. We show that Knuth’s generalization of Dijkstra’s algorithm for the shortestpath proble...
A Fresh Look at the Evaluation of Ordering Tasks in Reading Comprehension：Weighted Marking Protocol
Ordering Tasks Weighted Marking Protocol Reading Comprehension
2009/8/19
After briefly discussing techniques such as ‘the cloze test’ and ‘gap-filling’ employed in assessing reading, the main focus of the paper resides in the scoring process of ‘ordering tasks’, where stud...
Community Detection on Weighted Networks: A Variational Bayesian Method（图）
Community Detection Weighted Networks
2015/1/24
Massive real-world data are network-structured, such as social network, relationship between proteins and power grid. Discovering the latent communities is a useful way for better understanding the pr...
