If we define a boolean algebra as having at least two elements, then that algebra has a minimal element as 0 and maximal element as 1 . Each element has a unique complement, i.e., 0 complement =1and 1 complement =0. Let us add a third element y, which is distinct from 0 and 1. It has to have a complement of y as y*, and y* is not equal to 0 or 1 (since y is not equal to 0 or 1). Also, y*≠y(if it were y∨y∗=1 would not hold). So this algebra has 4 elements, and not 3. This is proof about this..

Suppose a tweet is represented as a tuple (tweet id, Boolean, Boolean). The second Boolean element will be True if the tweet matches Twitter REST API Query otherwise, it will be False. The third Boolean element will be True if the tweet content is positive (relevant to the topic of interest); Otherwise, it will be False. The whole twitter space is represented as the set of tweets: Suppose the crawled tweets using Twitter REST API Query is represented as the...

Let ? be a Boolean algebra and ?,? two elements of ?. Use properties of Boolean algebras to find the solution of the equation (i.e., solve for ?x) a⋅x+b¯=0 in term of ?a and ?b according to conditions in each item. a) What is the solution set of the equation above if ?=1a=1 and ?=1b=1? Justify your answer. b) What is the solution set of the equation above if ?=1a=1 and ?=0b=0? Justify your answer.

Boolean algebra serves to relate logical quantities. The Boolean expression for the OR operation is C = A + B. Look up and write the Boolean expression for the AND operation. Write the truth table of the three-input operation D = A + (BC). Using truth tables, show that NOT(A + B) = (NOT(A))(NOT(B)) and similarly that NOT(AB) = ?
