Scene Division Research For Text-to-scene Conversion

Text is a way for people to express their perception of the real world,and vision is the window for human to understand the world.People can communicate more conveniently and efficiently by visualizing the meaning of text.The text-to-scene conversion is the process of automatically converting the natural language text description about the objective world perception into a visual scene or animation through a computer.It has important practical significance in education,military,design and communication.The scene information in text-to-scene conversion is all from the text.It has become a key issue in the current research of text-to-scene conversion that automatically identifies scene information from text.Scenes division is one of the main contents of scene information identification in text-to-scene conversion.It refers to automatically identifying the amount and structure of scenes from input text.However it still lacks the systematic basis theory and effective solutions.Facing the situation,this paper proposes the definition of the scene by analyzing the characteristics of scene from text-to-scene conversion,and explains the various elements of the scene.According to the definition of scene,the nature of scene is obtained,and then it is explained.The scenes are classified from different perspectives,giving the basis and results of the classification,then analyzing the scene characteristics of different categories,and summarizing the scene relationships of multiple scenes.Aiming at the scene text of the theme feature,the method of scene division based on theme is proposed by establishing the entity dictionary associated with theme.It identifies scene theme and realizes the scene division.Aiming at the scene text of the time feature,the scene division method based on time is proposed by establishing the rules of matching time word.It identifies time element in the scene text and realizes the scene division.Aiming at the scene text of the space feature,the method of scene division based on space is proposed by establishing the set of geospatial words,the set of related category space words,and the rules of matching director space words.It identifies space element in the scene text and realizes the scene division.Finally,the method of scene division combining time and space is proposed.The experimental results show that the proposed method in this paper can identify the input scene text,and realize the scene division.It also proves the validity and feasibility of the basic theory and technical route proposed in this paper.
