Title: Decision Analysis in the context of Geospatial Queries Interpretation

Abstract: We propose a decision analysis technique based on the Naïve Bayesian network for the analysis of geospatial queries. This limited domain space and the relevant semantic information present in the queries has made it possible to apply a simple natural language processing technique in determining the intent behind a user’s query. The model that we propose is simple to develop and can be used to interact with any geospatial system which is task specific in nature. We demonstrate the working of the model by means of an experiment and reason that the semantic properties of geospatial queries lend to the success of the model.
