Algorithm 2

The generation process of CLDA.

(1) For each topic ,

Choose long text multinomial distribution over terms, .

Choose short text multinomial distribution over terms, .

(2) For each document

(a) If there is a long text of a microblog text associated with a interest preference

under a specific area of the current user, the subject of the multi-distribution of

long text and short text is selected together, , . Conversely,

only the topic of the multinomial distribution of the short text relational documents

,

(3) For each of the words

Choose a topic ;

Choose a word ;
