With　the　development　of　big　data,　the　heuristic　query　based　on　the　semantic　relationship　network　has　become　a　hot　topic,　which　attracts　much　attention.　Due　to　the　complex　relationship　between　data　records,　the　traditional　query　technologies　cannot　satisfy　the　requirements　of　users.　To　this　end,　this　paper　proposes　a　heuristic　query　method　based　on　the　semantic　relationship　network,　which　first　constructs　the　semantic　relationship　model,　and　then　expands　the　query　based　on　the　constructed　semantic　relationship　network.　The　experiments　demonstrate　the　reasonableness,　high　precision　of　our　method.
