This is an interesting challenge you have. However, this list is for proposing ideas for changes in the Python language itself, in particular the CPython reference implementation. Python-list or some discussion site dealing with machine learning or natural language processing would be appropriate for the task you are trying to figure out. I suspect that third party libraries contain the data structures you need, but I cannot recommend anything specific from my experience.

In order to detect conceptual plagiarism, I need to populate a data structure with if/then equivalents as a decision tree. But my equivalents have potentially infinite ways of arranging them syntactically* and* semantically.

A dict having keys with identical set values treats each key as a distinct element. I am dealing with semantics or elemental equivalents and many different statements treated as equivalent statements involving if/then (key/value) or a implies b, where a and/or b can be an element or an if/then as an element. Modeling the syntactic equivalences of such claims is paramount, and in order to do that, I need the data structure.

Hello, I am Stephanie. I have never contributed to any open source. I am about intermediate at python and I am a self-directed learner/hobbyist. I am trying to prove with my code that a particular very famous high profile pop debate intellectual is plagiarizing Anders Breivik. I can show it via observation, but his dishonesty is dispersed among many different talks/lectures. I am dealing with a large number of speaking hours as transcripts containing breadcrumbs that are very difficult for a human to piece together as having come from the manifesto which is 1515 pages and about half copied from other sources. The concepts stolen are rearrangements and reorganizations of the same identical claims and themes. He occasionally uses literal string plagiarism but not very much at once. He is very good at elaboration which makes it even more difficult.

Stephanie: Welcome. The "Python idea" here is to allow a broader range of types as keys to a dictionary. The gap appears to be that certain types (like set) "don't work" as keys (or rather their identities not values work), but this is a misunderstanding. A set is mutable: it is as if, in an ordinary dictionary (lexically sorted), one were to allow changes to the spelling of a word while keping the definition. It's not unreasonable to do, but the entry is now potentially in the wrong place and ought to be re-inserted so someone can find it. Others have rightly suggested python-list as a place you could explore how to construct the data structure you need, using existing features of Python. However, I'll just mention that frozenset is worth a look. Jeff Allen On 17/03/2019 16:35, Savant Of Illusions wrote:
