    面向文景转换系统的空间本体库体系结构

    Architecture of Spatial Ontology for Text-to-Scene Conversion System

    • 摘要: 空间概念转换是文景转换系统中的基本任务.空间本体库是在SUMO顶层体系框架下,结合文景转换特定领域要求,基于领域空间本体模型构建特定领域空间本体库.其本体描述的空间概念能够有效地弥补自然语言系统和图形系统之间的差别,把对于图形系统来说自然语言描述中缺失的信息补充上,即完善自然语言系统固有的模糊性,从而完成空间概念的转换,提升生成场景的美观性.这个本体库在面向汉语的静态文景转换中得到测试,且取得很好结果.

       

      Abstract: Spatial concepts conversion in text-to-scene conversion systems (TTS) is one of the basic tasks. Spatial concepts conversion is to transfer the object locations specified with natural language into the objects display in the virtual scene. In the present, there are some methods including image schemes, expert knowledge base and graphic annotation to resolve the spatial concepts conversion in TTS. The problems of these methods are human labor consumed and skilled art training needed. In this paper, an architecture of spatial ontology for domain of text-to-scene conversion is provided, which makes up the gap between natural language system and graphic system from spatial concept point of view and improves the acceptability of the output scene. The architecture of domain spatial ontology is designed on the domain spatial ontology modol in the framework of SUMO top level. The architecture has two levels, one is the top derived from SUMO top level and has 8 nodes, and the other is the low defined on the features of TTS domain and composed of subclasses of nodes of SelfConnectedObject, Relation and Attribute from the top level. The spatial ontology is tested in the experiment of objects displayed on Chinese text in the text-to-scene system and a good result is gotton.
