Algorithm 1

LDA ELT topic word set construction algorithm.

	Input:
	//ELT corpus and ELT topic probability distributions
	Output: //LDA ELT subject headings
(1)	for i = 1 to m do//traverse ELT D
(2)	//Get the topic T to which the i-th ELT topic probability maximum belongs
(3)
(4)	//put the i article of ELT into the th topic
(5)	Topic.append (, i)
(6)	end for
(7)	for j = 1 to k do//traverse k topics
(8)	//ELT splitting and deduplication in the j-th topic
(9)	lexical ← set(seg(Topic[j]))
(10)	append(lexical)//constitute a set of subject words .
(11)	end for
(12)	return (Z)//return to LDA ELT subject word set
