Abstract: In heterogeneous information spaces,entities and associations generally have time information,entities of multiple time versions coexist.While traditional entity integration (EI) ignores time information,does not support the integration on the time dimension.In this paper,a time-aware EI framework in heterogeneous information spaces T-EI was proposed,which can aggregate large collections of heterogeneous entities into a set of clean and complete entity profiles with time information to support time-aware entity search.T-EI adopts time-aware entity resolution algorithm leveraging time information of entities and associations,and adopts time-aware data fusion algorithm considering data currency.Experimental results on the real data sets demonstrate the feasibility and effectiveness of T-EI.

Key words: Heterogeneous information spaces,Time-aware,Entity integration,Entity profile
