Knowledge Expression And Case-based Reasoning Of Ancient Architecture Based On Ontology

At present,in the field of ancient architecture heritage digital protection,people with different professional backgrounds have joined the ancient architecture protection project.However,due to the misunderstanding of the knowledge of ancient architecture by most people and the different formats of multi-source information sources,all parties have exchanged information.When obstacles are encountered,work efficiency cannot be improved.In addition,existing cases of ancient buildings cannot provide large-scale and efficient technical references for the repair of ancient buildings,resulting in the low utilization rate of ancient cases in the past and the inability to reuse knowledge from them.This article proposes a unified expression method of ancient architecture knowledge based on ontology-based ancient architecture knowledge expression and case reasoning,and uses the damaged case as an example to realize the reuse of ancient architecture knowledge.First of all,this paper sorts out the status quo of protection of ancient buildings,and finds that ontology technology can provide a unified knowledge expression method of ancient buildings.Therefore,this article proposes to introduce ontology technology into the expression of ancient building knowledge,and to establish the expression of ancient building knowledge based on ontology.Among them,the knowledge framework of ancient architecture was established by analyzing the knowledge of ancient architecture.From the perspectives of design,construction and repair of ancient buildings,the ontology-based ontology model of ancient buildings,the ontology model based on ancient building craftsmanship and the damaged ontology model of ancient buildings are proposed respectively.The corresponding ontology of the software is used to verify the example.By establishing the framework of ancient building rules,the rules of ancient building construction rules and ancient building damage rules were expressed by using SWRL language,and this was used as the theoretical basis of ontological reasoning.Secondly,based on the ontological knowledge of ancient buildings,the case-based reasoning technology is introduced into the field of ancient building protection,and the representation of ancient building damage based on ontology is proposed.Based on this,an optimization method for attribute weights based on rough sets and information entropy in the context of multiple attributes is proposed.Based on the analysis of the attributes of ancient building damage cases,a two-stage case retrieval is proposed.And the example is used to verify the reasoning based on the ancient building case.The ontology-based ancient architecture knowledge expression proposed in this paper establishes a unified semantic expression form of ancient architecture,eliminates the cognitive bias of ancient architecture from different professions,and lays the foundation for the multi-party interaction of ancient architecture information.Ancient building knowledge ontology provides the expression paradigm and reasoning basis for the damaged case expression.Based on the ontology,the ancient building damaged case reasoning excavates the implicit knowledge from previous cases,and through case reasoning,it realizes the reuse of ancient building case knowledge and digitizes ancient buildings Protection provides the foundation.
