--The paper had to main goals: 1) to find mismatched cross lingual topics and use their algorithm to correct the cross lingual links and 2) to extract some cross language named entity pairs. +  * The paper had to main goals: 
--We discussed the general algorithm and its approach to using distinct sets of categories and its approximation algorithm for weighted distinctness graph separation. +     - to find mismatched cross lingual topics and use their algorithm to correct the cross lingual links and 
--We discussed the use of bots in wikipedia to populate the links. It was unclear how many of the poor links are bot generated. It was suggested that it would be useful to augment the algorithm if wikipedia indicates in the change log which links came from bots (it was not clear f this was possible).+     - to extract some cross language named entity pairs.

--It was unclear in Figure 1 what was simplified. The figure is also directed but does not show it graphically which made it difficult to figure out if we could have a term going to multiple languages. +  * It was unclear in Figure 1 what was simplified.
