De Morgan's laws commonly apply to text searching using Boolean operators AND, OR, and NOT. Consider a set of documents containing the words "cars" and "trucks". De Morgan's laws hold that these two searches will return the same set of documents: Search A: NOT (cars OR trucks) Search B: (NOT cars) AND (NOT trucks) The corpus of documents containing "cars" or "trucks" can be represented by four documents: Document 1: Contains only the word "cars". Document 2: Contains only "trucks". Document 3: Contains both "cars" and "trucks". Document 4: Contains neither "cars" nor "trucks". To evaluate Search A, clearly the search "(cars OR trucks)" will hit on Documents 1, 2, and 3. So the negation of that search (which is Search A) will hit everything else, which is Document 4. Evaluating Search B, the search "(NOT cars)" will hit on documents that do not contain "cars", which is Documents 2 and 4. Similarly the search "(NOT trucks)" will hit on Documents 1 and 4. Applying the AND operator to these two searches (which is Search B) will hit on the documents that are common to these two searches, which is Document 4. Please write a Python program to De Morgan's Law via document search. You can use four text files as document 1, 2 3 and 4. Search A: NOT (cars OR trucks) set A = list of all docs (a, b, c, d) set B = list of docs with trucks (a, c) set C = list of docs with cars (b, c) set D = list of docs with cars or trucks (a, b, c) set E = not D (d) Search B: (NOT cars) AND (NOT trucks) set A = list of all docs (a, b, c, d) set B = not cars (a,d) set C = not trucks (b,d) set D= (not Cars AND not Trucks) (d) d = {} d['cars'] = [a, c] d['trucks'] = [b, c] def get word_count(word, file): n = 0 x = open(..)
