The invention discloses a topic-based community search method on a heterogeneous information network, which comprises the following steps of: firstly, extracting topics of nodes carrying text information from text description information of a target heterogeneous information network, and then carrying out topic aggregation on nodes with the same type as a target query node; reconstructing the target heterogeneous information network according to a given meta-structure, returning a new heterogeneous information network with a smaller scale reconstructed according to the mode of the meta-structure, and returning a meta-path equivalent to the meta-structure; and finally, on the obtained new heterogeneous information network, according to the new meta-path and the input target query node, performing community search by adopting an existing method for performing community search according to the meta-path, and searching communities which are closely associated with the target query node and have similar themes. 本发
