Semantic Information Extraction of the Query Conditions in GIS Chinese Query Sentences
Huang Yuan · Computer Engineering and Science · 2007
No matter how much complicated Chinese query sentences may be, they are always made up of query targets and query conditions. The structure of a query sentence is determined by the query conditions. The query conditions can be parallel or nested. The order of query conditions are also not fixed. The semantic information extraction of the query conditions are studied based on information extraction in this paper.The rules of extraction are made and serveral algorithms are presented. The query conditions and Sub-SQL are integrated into the algorithms. The exprements show that these algorithms can extract effectively the semantic information of query conditions. They are worth of further research.
