Abstract
The development cycle of machine translation (MT) systems includes important stages such the evaluation, error analysis, and system refinement. These stages have promoted several research studies and tools focused on aiding the tasks of MT developers.
This master thesis is concerned with the error analysis stage. We have developed the tSearch tool, an open web-based application that aims to facilitate the qualitative analysis of translation quality. So far, MT developers usually have to tackle the tedious and time- consuming task of inspecting a large set of translations almost manually. There exist some tools focused on the classification of the error types. In contrast, tSearch offers a new focus providing mechanisms for doing complex searches over a collection of translation cases evaluated with a large set of diverse translation evaluation measures, which makes easy the discovery of patterns that may help MT developers to improve the translation quality. Thus, the error analysis task can be carried out over a specific subset of translations examples, turning into a more efficient and feasible work.
