Semantic Similarity of Natural Language Spatial Relations
Communication problems between humans and machines are often the reason for failures or wrong computations. While machines use well-defined languages and rules in formal models to compute information, humans prefer natural language expressions with only vaguely specified semantics. Similarity comparisons are a central construct of the human way of thinking. For instance, humans are able to act ...
متن کاملModeling Spatial Knowledge from Verbal Descriptions
Over the past few years, several alternative approaches have been suggested to represent the spatial knowledge that emerges from natural environments. This paper introduces a rule-based approach whose objective is to generate a spatial semantic network derived from several humans reporting a navigation process in a natural environment. Verbal descriptions are decomposed and characterized by a g...
متن کاملAcquisition of Landmark Knowledge from Spatial Description
Maps and spatial descriptions are two different styles in expressing geographical information. Each style has its own merits and demerits. When information is given in one style, it is sometimes required to convert it to the other style. A vast amount of spatial descriptions are available electronically, especially on the World Wide Web. If geographical knowledge extracted from spatial descript...
متن کاملAcquisition of Conceptual Data Models from Natural Language Descriptions
Acquiring information systems specifications from natural language description is presented as a problem class that requires a different treatment of semantics when compared with other applied NL systems such as database and operating system interfaces. Within this problem class, the specific task of obtaining explicit conceptual data models from natural language text or dialogue is being inves...
متن کاملIncremental Models of Natural Language Category Acquisition
Learning categories from examples is a fundamental problem faced by the human cognitive system, and a long-standing topic of investigation in psychology. In this work we focus on the acquisition of natural language categories and examine how the statistics of the linguistic environment influence category formation. We present two incremental models of category acquisition — one probabilistic, o...
