With its versatility in processing and exploring corpus data, the limitations we encountered with this framework so far lie in two aspects: First, due to the free service provided by Google, the experiment is largely dependent on the services provided by the  Table APIs commercial company, which could be a weak point in terms of stability in the future; and (2) what is also at stake here is indeed the embedded use of other tools and APIs can be a problem due to their compatibility with Google services.
with the downside mentioned, we believe that much more can be improved with respect to the likelihood of future convergence for the open collaboration between academic and commercial fields.
