Embodiment Construction

[0042] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] refer to figure 1 A method for incomplete partitioning of the largest cardinality subset of an ontology library according to an embodiment of the present disclosure is described.

[0044] Such as figure 1 As shown, an incomplete partition method S100 of the largest cardinality subset of an ontology library, the method S100 includes:

[0045] Step S110, according to the ontology library B containing logical conflicts and the limited coordination cluster number k of the ontology library B, obtain m minimal incompatible subsets O of the ontology library B through an existing algorithm i (i=0,1,...,m-1) constitute the minimal incongruous subset set MIS(B) and the problem formula set Prob(B), and construct the model...

Abstract

The invention provides an incomplete division method and device for a maximum cardinal subset of an ontology library. Comprising the following steps: according to an ontology library containing logic conflicts and a limited coordination cluster number k, obtaining a minimum uncoordinated subset set and a problem formula set, and building a model decision variable set X and model auxiliary decision variable sets Q and Y; constructing a quadratic integer programming constraint C according to k, X, Q, Y and the minimum discordant subset; enabling the sum of X to form a quadratic integer programming objective function Z, solving the minimum value of Z under the condition that C is met, obtaining a variable assignment set, obtaining different clusters through different integer values corresponding to each formula in the problem formula set in the variable assignment set, and dividing the clusters into limited coordination clusters which keep the maximum cardinal subset of the input ontology library; constructing a quadratic integer programming model by using the minimum incongruous subset, and finally solving the model to incompletely divide the ontology library into limited coordination clusters and enable the limited coordination clusters to retain the maximum cardinal subset in the ontology library.

Description

technical field [0001] The disclosure belongs to the technical field of an incomplete partition method of an ontology database containing logical conflicts, and specifically relates to an incomplete partition method and device for an ontology database maximum cardinality subset. Background technique [0002] Ontology is one of the important knowledge representation tools of artificial intelligence and the theoretical basis of Semantic Web services, which has been widely used in many fields of computer science. In 1993, Gruber gave a formal definition of ontology that is widely accepted in the field of information science, that is, "ontology is a clear specification of a conceptual model". However, in ontology construction, due to various subjective and objective reasons, such as insufficient understanding of knowledge by ontology builders, inconsistencies caused by ontology descriptions, polysemy, etc., it is almost impossible to construct ontology without conflicts. At the...
