This is the function that allows the insertion of sentence and probabilities in order to create a knowledge base. For doing this follow the structure:
Where sentence is the sentence you want to insert. The arguments lowprob, upperprob are, respectively, the lower and upper probabilities of the sentence.
Note that the last two arguments can be omitted, inserting, then, sentences without a specific probability interval. If only one was omitted, the function will interpret as if the lower and upper probabilities are equals.
