Research On Construction Method Of Conceptual Graph Gallery For Collaborative Communication

Collaborative communication is an important way to carry out multi-expert cooperation and cross-disciplinary research.Researchers in various fields of geography need to collaborate to share and merge ideas,explore solutions for the comprehensive simulation analysis of complex geographic systems,to support a more comprehensive geographic cognition.With the development of Internet and communication technology,tools and platforms for assisting experts to carry out collaborative communication are becoming abundant.However,the technical solutions nowadays,which are typically distributed and collaborative communication,mainly focus on the message exchange strategy itself,rarely involve the exchange of professional knowledge required to tackle geographic issues.Geographic modeling and simulation as a necessary way to solve geographic problems,the accuracy of the modeling simulation results largely depend on the understanding of the problem.Therefore,how to reduce the communication barriers between different scientific researchers in the process of tackling problem is an important content of carrying out comprehensive geographic simulation work,and is also the main start for this research.This study takes the actual needs for multi-researchers' collaborative communication in geographic modeling activities as the traction.Taking land hydrology as an example,the structured expressions of land hydrological knowledge concepts are used as bridge for researchers to communicate and understand each other,providing a collaborative communication medium.Based on the designed land hydrological conceptual graph gallery,under the support of natural language processing methods and knowledge expression methods,we construct a collaborative communication scenario to understand geographic problems,assisting multi-researcher to carry out the exchange of land hydrological knowledge and promote cooperative hydrological modeling and simulation work more effectively.The specific research content and results of this study are as follows:(1)Study on the construction method of land hydrological concepttual graph gallery.The construction of the structured land hydrological concepts description framework serving the construction of land hydrological conceptual graph gallery is designed.A set of classification structures for land hydrological concepts is proposed,which governs land hydrological concepts and make them systematic;a multi-dimensional description structure for land hydrological concepts is proposed,and a method for graphical association of land hydrological concepts is studied,so that the expression of land hydrological concepts has both formal description information and associated visualization Icon resources.Based on the land hydrological concept structured description framework,the structural design of the land hydrological concept gallary was completed.Finally,through the non-relational Mongo DB database,the structured storage of the land hydrological conceptual graph gallery is realized.(2)Research on collaborative communication method based on land hydrological conceptual graph gallery.Using the land hydrological conceptual graph gallery as a medium for multi-researchers to collaborate and communicate,to help researchers understand geographic issues more easily and communicate geographic issues more easily as a demand-oriented,with the support of natural language processing technology and knowledge expression methods,text Communication-led and graphic communication-led collaborative communication scenarios is constructed,retrieval and reasoning mechanisms are integrated into the scenarios to support cross-field researchers to improve their understanding of geographic issues from different perspectives,and guide the subsequent modeling and simulation phases based on cognition.(3)Experimental verification of the prototype system for collaborative communication in the land hydrological conceptual graph gallery.Through the research on the construction method of the land hydrological conceptual graph gallery and the collaborative communication method based on the land hydrological conceptual graph gallery,this paper builds a network-oriented and open collaborative communication prototype system.On the one hand,the prototype system supports multiple researchers to participate in improve and expand the resources of the land hydrological concepts gallery.On the other hand,the resources of land hydrological concept gallery are used as the materials for researchers to communicate with each other,which supports researchers to communicate geographic issues more conveniently and improve their understanding of geographic issues.Taking the concept of Tongjiang Lake as an example,a conceptual system framework with Tongjiang Lake as the core was sorted out.Based on this framework,the water pollution of Poyang Lake was taken as the communication theme to verify the scientificity and practicability of the prototype system.On the one hand,this research can help multi-disciplinary researchers to comprehensively understand land hydrological knowledge,weaken communication barriers caused by poor disciplinary knowledge background,form an overall understanding of geographic issues,and pave the way for geographic modeling.On the other hand,this study takes the land hydrology as an example,and the research on the expression methods of domain knowledge concepts can also provide experience for other disciplines to carry out related research.
