Big Idea

The motivation of the two papers are the same. That is there are a large amount of resources in English and they want to use them in target language where there are fewer resources.

Method

The main difference of the two paper is that, although they all use the parallel corpus 1) Rada Mihalcea use it in a way to project the word in the source language directly to the target language, and use the information (annotation) of the source language word to label the target language word. 2)While BinLu train a MaxEnt-based model then maximizes the joint probability, in which they consider both the language at the same time which is a more promising way in my opinion.

Problem

The problem they deal with is quite similar. Although Rada Mihalcea's work more focused on subjective analysis while the BinLu's work more focused on sentiment analysis on sentence level. They big problem is quite the same. They both want to draw lexicons (mainly) from the source language, and label the target language lexicons which contains information in dealing with the specific task.

Other

Although they all achieve good results in experiments, Rada Mihalcea and BinLu suffers from a same problem which is that, no matter using the dictionary based methods like in Rada Mihalcea's first apporach, or using the parallel corpus (used for alignment in Rada's and use google translation) the lexicon is quite limited actually. Which means, use can get a substantial amount of useful lexicons, but quite many lexicons which are actually very important for the specific task got ignored since they even do not appear in the auto-translation text or the standard dictionary. This will be even more harmful than the ambiguity problem.
