Algorithm 2

Genetic algorithm-based word sentiment value calculation.

Input:
//ELT corpus, ELT topic collection, ELT topic word collection
Output:
/minimum variance individual (optimal sentiment value of topic word set words)
(1)	//Randomly generated populations P
(2)	for j = 1 to MAX do//MAX is the maximum number of iterations
(3)	for ch = 1 to M do//traverse the population
(4)	fit ← fitness (ch)//calculate individual fitness
(5)	fitness.append (fit)//save fitness
(6)	end for
(7)	new_p ← select(P, fitness)//select operation
(8)	new_p ← cross(new_p)//cross operation
(9)	new_p ← mutation (new_p)//mutation operation
(10)	p ← new_p//new population P
(11)	end for
(12)	//Minimum variance individual
(13)	//Return the minimum variance individual
