Research On Urban Square Space Based On Semantic Network Pattern Language

With the development of the economy and the acceleration of urbanization,people's life rhythm has become faster and faster.Urban dwellers who grow in a reinforced concrete environment are more eager to get in touch with nature and feel the natural.The construction of urban squares not only enriches the urban space,but more importantly,it provides a pleasant outdoor green space for the citizens,meeting the needs of people for leisure,entertainment and communication.The square is for people,and the square space is closely related to people's activities.Objectively analyzing the various elements of the square space will help to further analyze the gains and losses of the square space design,which will help to further improve the structure of the space and have guiding significance for future theories and practices.Firstly,the semantic network method and pattern language are combined to extract the prototype of urban square space and extract the spatial elements of urban square space,so that the spatial elements and structural analysis of urban square are more clear and intuitive.Through the semantic network model,we find that the function of city square is gradually enriched.it is shown that the formation of a complete square space requires the interaction of multiple elements,and each element also has mutual influence.Secondly,according to the established the prototype of the city square,characteristics of different type of city square,memorial square,municipal square,commercial plaza,deductive analysis traffic square,leisure square,and through the establishment of a typical case of the semantic network model analysis of elements of the space,put forward reasonable Suggestions,provide people with more reasonable and more enrichment square design references.At the same time,through deductive analysis,the rationality of the mode combining the two methods can be verified.Finally,using the concept of knowledge element,the spatial database of city square is established,and the semantic network pattern language model is brought into the computer program,forming the preliminary research of computer application.Then,taking Protégé as an example,the analysis results of the semantic network pattern of city square are expressed with Protégé.By applying the pattern of computer application,the development of semantic network pattern language for computer application is further verified,which has the trend expression oriented to computer application.
