Our criteria mainly depended on internal testing to see which pre-packaged algorithms performed better on our data. While performance does vary with the domain (or in our case, industry of feedback we are analyzing), we have found it to be more efficient to find the overall effectiveness of one platform and deploy it for all of our analysis.

As far as the domain affecting the algorithm, it can vary from some algorithms maintaining decent performance over most industries, to some algorithms working very well for some industries and terribly for others. Although it is just feedback, the topic of the feedback and even the ways people talk about the same topic (such as price of the product) will vary across each industry.
