Abstract
In the present work we study semi-automatic evaluation techniques of machine translation (MT) systems. These techniques are based on a comparison of the MT system's output to human translations of the same text.
Various metrics were proposed in the recent years, ranging from metrics using only a unigram comparison to metrics that try to take advantage of additional syntactic or semantic information. The main goal of this article is to compare these metrics with respect to their correlation with human judgments for Czech as the target language and to propose the best ones that can be used for an evaluation of MT systems translating into Czech language.
