The question is too far up in fuzzy space. Narrow down to several use cases and specific problems within those and search field will be more manageable. Examples: Social workers want to be able to handle more cases appropriately. How many cases can they handle without diminishing quality scores. Politicians want to appear caring to the needs of as many constituents as possible. How do they group needs into buckets to find what is most relevant. Find the overlap and dig into it with more cases and then questions.
Like automating the analysis of a recorded argument according to Gottman institute and other social heuristics for augmentation of marriage counseling services?
[edit: i.e. count positive and negative sentiment statements assigned to speakers and compare the per speaker ratio to the experimentally determined minimum "healthy" ratios not yet replicated]
You're right that there needs to be a tractable starting place. This is not lost on me. I may have used a flexible definition of "close to solving" but one's interpretation also fits into the scope of the effort. I'm at least 10% into it! ;P
