A website for comparing of universities, institutes all over the world

The website seems to use very inaccurate data. For example, compare the publication records of John Hutchinson:

• this website (academic research microsoft)
  
• researcherID

Yes it seems many papers are missing, and even more citation links. I guess the data are however statistically significant for comparison purposes. Some fields may be missing altogether. It does produce reasonable outputs. For example in engineering see the list. Strange Cambridge UK is so low.
