Fuzzy Query for Scalable Vector Graphics Format Map Based on Layer Definition

Abstract:

A fuzzy query model for scalable vector graphics(SVG) format maps with layer definitions is proposed in this paper. In the model, a word repository is constructed to store the related words and fuzzy query patterns. When users execute queries, a word segmentation subalgorithm decomposes the query statement into words according to the word repository. Then a semantic analysis subalgorithm converts the words to the fuzzy query patterns. The fuzzy query patterns are connected with the elements on a related layer or layers in an SVG format map. These elements will be highlighted as query results. Experiments are conducted to validate the effectiveness of the proposed model.
