  Entity information network is used to describe structural relationships
between entities. Taking advantage of its extension and heterogeneity, entity
information network is more and more widely applied to relationship modeling.
Recent years, lots of researches about entity information network modeling have
been proposed, while seldom of them concentrate on equipment-standard system
with properties of multi-layer, multi-dimension and multi-scale. In order to
efficiently deal with some complex issues in equipment-standard system such as
standard revising, standard controlling, and production designing, a
heterogeneous information network model for equipment-standard system is
proposed in this paper. Three types of entities and six types of relationships
are considered in the proposed model. Correspondingly, several different
similarity-measuring methods are used in the modeling process. The experiments
show that the heterogeneous information network model established in this paper
can reflect relationships between entities accurately. Meanwhile, the modeling
process has a good performance on time consumption.
