The Scenario: A group of people must summarize specific parts of speeches they hear. They hear a new speech every day, and it's possible that multiple members of group are listening to the same speech.
The Question: What ml algorithm or approach could you take to link summaries that refer to the exact same part of the exact same speech?
Why this question is interesting: most classification problems deal with a large amount of instances and only a few classes. This problem is about dealing with very few instances (1-5) for a growing number of classes (The specific part of the specific speech).
