【摘要】：隨著對(duì)地觀測(cè)技術(shù)和計(jì)算機(jī)網(wǎng)絡(luò)技術(shù)的迅速發(fā)展，獲取空間信息的方式越來越多樣化，然而，要從海量的空間信息中快速地提取所需的信息資源，獲取高質(zhì)量的空間信息服務(wù)就相對(duì)困難了。為空間信息和空間信息服務(wù)賦予語義，就可以被計(jì)算機(jī)理解并識(shí)別，實(shí)現(xiàn)精確的匹配，查找出所需的信息和服務(wù)，有利于空間信息的共享。然而，目前對(duì)空間信息服務(wù)的語義表達(dá)還存在一些不足之處，為了完善和深入地研究空間信息服務(wù)的語義表達(dá)機(jī)制，使空間信息和空間信息服務(wù)帶上語義，本文對(duì)此開展了相關(guān)研究。 本文從空間信息服務(wù)的不足入手，尋求帶語義的解決方法。在分析現(xiàn)有研究成果的基礎(chǔ)上，提出利用OWL和OWL-S分別從概念層面和應(yīng)用層面表達(dá)空間信息的語義和空間信息服務(wù)本身的語義。主要的研究?jī)?nèi)容如下： 首先，引入地理本體來描述空間信息的概念和概念之間的關(guān)系，，解決空間信息在概念層次上的語義表達(dá)。采用UML建模工具對(duì)地理本體進(jìn)行建模，并使用網(wǎng)絡(luò)本體語言O(shè)WL形式化表達(dá)地理本體模型。 其次，利用建立的地理本體模型創(chuàng)建了地理本體實(shí)例，并使用開源的MySQL數(shù)據(jù)庫對(duì)實(shí)例進(jìn)行了存儲(chǔ)，通過實(shí)驗(yàn)驗(yàn)證本文創(chuàng)建的地理本體模型可以較好地表達(dá)空間信息的概念。 最后，構(gòu)建空間信息服務(wù)本體，通過一個(gè)空間信息服務(wù)實(shí)例，采用OWL-S從服務(wù)的概要語義、服務(wù)的執(zhí)行語義以及服務(wù)的調(diào)用語義這三方面來表達(dá)空間信息服務(wù)本身的語義，并在這個(gè)服務(wù)實(shí)例的語義表達(dá)基礎(chǔ)上設(shè)計(jì)開發(fā)了一個(gè)服務(wù)調(diào)用的測(cè)試程序，用實(shí)驗(yàn)驗(yàn)證采用空間信息服務(wù)的語義表達(dá)機(jī)制能夠?qū)崿F(xiàn)計(jì)算機(jī)的自動(dòng)識(shí)別，為空間信息的語義共享與互操作提供了參考。 研究表明，采用OWL和OWL-S來表達(dá)空間信息服務(wù)的語義，可以被計(jì)算機(jī)理解、識(shí)別并執(zhí)行調(diào)用，為實(shí)現(xiàn)空間信息服務(wù)的智能化提供了一些借鑒和參考。
[Abstract]:With the rapid development of Earth observation technology and computer network technology, the methods of obtaining spatial information are becoming more and more diversified. Access to high quality spatial information services is relatively difficult. By giving semantics to spatial information and spatial information services, it can be understood and recognized by the computer, and the exact matching can be realized, and the needed information and services can be found out, which is beneficial to the sharing of spatial information. However, there are still some shortcomings in the semantic representation of spatial information services. In order to improve and deeply study the semantic expression mechanism of spatial information services, spatial information and spatial information services are brought with semantics. This article has carried on the related research to this. This article starts with the deficiency of spatial information service, and seeks the solution with semantic. Based on the analysis of the existing research results, it is proposed to express the semantics of spatial information and the semantics of spatial information services from the conceptual level and the application level by using OWL and OWL-S, respectively. The main contents of the study are as follows: Firstly, geographical ontology is introduced to describe the concept of spatial information and the relationship between concepts, and to solve the semantic representation of spatial information at conceptual level. UML modeling tool is used to model geographical ontology, and network ontology language OWL is used to formalize geographical ontology model. Secondly, the geographical ontology instance is created by using the established geographical ontology model, and the instance is stored using the open source MySQL database. It is verified by experiments that the geographical ontology model created in this paper can express the concept of spatial information better. Finally, the ontology of spatial information service is constructed. Through an example of spatial information service, OWL-S is used to express the semantic of spatial information service from three aspects: the summary semantics of the service, the execution semantics of the service and the invocation semantics of the service. Based on the semantic representation of the service instance, a test program of service invocation is designed and developed. The experiment proves that the semantic representation mechanism of spatial information service can realize the automatic recognition of computer. It provides a reference for semantic sharing and interoperability of spatial information. The research shows that using OWL and OWL-S to express the semantics of spatial information service can be understood, recognized and called by computer, which provides some reference and reference for realizing the intelligence of spatial information service.
