Highway Intelligent Line Selection Personnel Knowledge Based On Ontology Modeling Method

Highway route selection is an important step in the process of highway construction, and its purpose is to meet the requirements of country’s economic development, and combine with the local natural conditions, and running fast, safe, comfortable vehicle for the basic objective, to select economically reasonable solution. The development of computer technology promotes the change of the line selection, it completed the transition of the artificial line selection to the three-dimensional virtual environment line selection.But intelligent route selection has not been used widely, expression and application of knowledge in the field of highway route has not yet to be noticed. The intelligent route selection in railway field already has been already have preliminary result, so the field of highway route should also carry out highway intelligent route selection method. Establishment of knowledge modeling and the knowledge base is based on the base of artificial intelligence methods, and it has an important role in the preservation of knowledge, enhance the value and knowledge of the effectiveness of play. Therefore, the Highway intelligent route selection for the field staff knowledge as the research object of knowledge modeling, representation, reasoning, building a database and query applications.Knowledge modeling and building a database needs to consider the sharing of knowledge in the field between man-machine knowledge interaction, ontology knowledge model can provide a knowledge sharing and interoperable middleware, used to describe the concept in the field of application selected line, the concept attributes, and relationships between concepts of constraint, and therefore the highway route of the domain knowledge model based on ontology construction. The paper carried out the following work:(1)In connection with the characteristics of the use of knowledge in the field of highway route, proposed using the ontology to establish the knowledge model of the highway route. Analyze the knowledge in the field of highway route, and the establishment of the description of the three-tier architecture model and road model characterization, and on this basis to establish the overall framework of the line selection system. Ontology theory applied to the knowledge model of the line selection, an effective description of the class of the field, and the relationship between classes and their attributes.(2) The knowledge representation of the line selection was systematic study and for the field staff for highway line domain ontology knowledge modeling method (DOHIRS,). The combination of Semantic Web knowledge representation and object-oriented methods to achieve the knowledge structure of the field of highway route, the concept of the relationship between concepts, properties, attributes modeling.(3) Using the proposed method to achieve the modeling of the highway route knowledge in domain-oriented staff, library, and the development of knowledge browsing, reasoning, and query the prototype system. Knowledge of the line selection modular design concept, using JAVA, JSP programming language for network development, and on this basis can the edit, and query operations on the knowledge base of the highway route. Using the JAVA language development kit JENA to have exploratory study of reasoning in the ontology model of the line selection and parsing.
