multi-part words in english language are hyphenated and hyphen is used to separate different parts. persian language consists of multi-part words as well. based on persian morphology, half-space character is needed to separate parts of multi-part words where in many cases people incorrectly use space character instead of half-space character. this common incorrectly use of space leads to some s...

This paper describes a decoding algorithm for a syntax-based translation model (Yamada and Knight, 2001). The model has been extended to incorporate phrasal translations as presented here. In contrast to a conventional word-to-word statistical model, a decoder for the syntaxbased model builds up an English parse tree given a sentence in a foreign language. As the model size becomes huge in a pr...

Currently the unified semantic role labeling (SRL) that achieves predicate identification and argument in an end-to-end manner has received growing interests. Recent works show leveraging syntax knowledge significantly enhances SRL performances. In this paper, we investigate a novel framework based on sequence-to-sequence architecture with double enhancement both encoder decoder sides. side, pr...

The development of accurate machine translation systems requires detailed analyses of the recurring translation mistakes. However, the manual inspection of the decoder log files is a daunting task because of their sheer size and their uncomfortable format, in which the relevant data is widely spread. For all major platforms, DIMwid offers a graphical user interface that allows the quick inspect...

Phrase-based decoding produces state-of-theart translations with no regard for syntax. We add syntax to this process with a cohesion constraint based on a dependency tree for the source sentence. The constraint allows the decoder to employ arbitrary, non-syntactic phrases, but ensures that those phrases are translated in an order that respects the source tree’s structure. In this way, we target...

In video communications over error introducing channels, error concealment techniques are widely applied in video decoder for good subjective images output. However, a damaged MB could be concealed only after it is detected as erroneous. Because of the poor performance of the traditional syntax based error detection schemes, the error concealments thereafter show bad results. Our previous work ...

Standards define a common language that different parties can use, so that they can communicate with one another. Standards are thus, a prerequisite to effective communication. Video coding standards define the bitstream syntax, the language that the encoder and the decoder use to communicate. Besides defining the bitstream syntax, video coding standards are also required to be efficient, in th...

We present a machine translation framework that can incorporate arbitrary features of both input and output sentences. The core of the approach is a novel decoder based on lattice parsing with quasisynchronous grammar (Smith and Eisner, 2006), a syntactic formalism that does not require source and target trees to be isomorphic. Using generic approximate dynamic programming techniques, this deco...

The specification of a decoder, i.e., a program that translates sentences from one natural language into another, is an intricate process, driven by the application and lacking a canonical methodology. The practical nature of decoder development inhibits the transfer of knowledge between theory and application, which is unfortunate because many contemporary decoders are in fact related to forma...

Beam search is a fast and empirically effective method for translation decoding, but it lacks formal guarantees about search error. We develop a new decoding algorithm that combines the speed of beam search with the optimal certificate property of Lagrangian relaxation, and apply it to phraseand syntax-based translation decoding. The new method is efficient, utilizes standard MT algorithms, and...
