In fact, he does a similar kind of analysis (that's why he has the different colors in the co-author table). Unfortunately this is not available in the xml-dump of the DBLP data he is providing, so I can't use it... Do you use the data in rkbexplorer? I could provide alternative 'author' links (or even replace mine; though I'm not sure how many people actually rely on the 'original' authors provided in DBLP). Also, If you can provide me with the data, I'm happy to take a look whether I could include it in my database. I guess I'd only need a new relation dblp_key <-> author (but I'd need a weekly update). +> In any case, Semantic Web applications having access to both the liberal and +> conservative treatments is all part of the rich tapestry. Yes, I wouldn't be using the (Semantic) Web if I expected to get 100% correct answers...
