I did a test on comparing Google and Baidu for side-by-side view of likes, dislikes, net sentiments, sources, etc.
So to summarize the different opinions of these two search giants from social media in Chinese:
2. most striking likes for Google are Cooperative, Innovation, Updated, Optimized and Robust. The likes for Baidu are optimized, updated, and new.
The dislikes of Google are Monopoly, abandoning Android, cannot open it (that is in fact not a problem of Google, it is Chinese Great Wall's problem). The dislikes of Baidu are unstable, drop, and misleading.
There are also a few obvious bugs too, like "very easy" misclassified as dislikes.
