基于Protégé的矿床成因类型本体推理判别方法——以中低温岩浆热液型金矿床为例

Ontology inference discrimination method for genesis types of ore deposits based on Protégé—A case study of medium-low temperature magmatic hydrothermal gold deposits

中低温岩浆热液型金矿床分布范围广,规模大,数量约占中国金矿床的65%,是中国矿产金的主要来源。在找矿过程中,不同矿床类型对应不同的找矿方法,确定矿床成矿模式能够为找矿提供理论支撑,并且能为矿产勘查和预测提供理论指导。鉴于此,结合勘查区找矿预测理论,对中低温岩浆热液型金矿床的本体构建和推理机制进行研究。利用Protégé本体建模软件,完成对矿床的本体建模,基于SWRL推理规则语言,定义矿床成因类型的推理规则,设计了一套面向矿床类型判别的本体推理机制,利用HermiT推理机完成推理。经大量试验,提出了矿床成因类型本体推理判别方法,其在金矿床成因类型判别方面具有较好应用效果,并可广泛应用于其他矿床成因类型的判别。

Medium-low temperature magmatic hydrothermal gold deposits are widely distributed and large in scale,accounting for about 65%of the gold deposits in China,which is the main mineral source of gold in China.In the process of prospecting,different types of deposits correspond to different prospecting methods.The determination of the metallogenic model of deposits can provide theoretical support for prospecting as well as theoretical guidance for mineral exploration and prediction.In view of this,the ontology construction and inference mechanism of medium-low temperature magmatic hydrothermal gold deposits are studied in this paper with reference to prospecting and prediction theory of exploration area.Using Protege ontology modeling software,the ontology modeling of the deposit is completed.Based on the SWRL inference rule language,the genesis type of the deposit is defined by inference rules.A set of ontology inference mechanisms oriented to the deposit type discrimination is designed.The inference is completed with the HermiT inference device.After a lot of experiments,the ontology inference method of the deposit genesis type proposed in this paper has a good application effect in the discrimination of gold deposit genesis types and can be widely used in the discrimination of other types of deposit genesis.
