Abstract
More and more scientists put their focus on the phenomenon of “information explosion.” recently. Moreover, the studies of Geographical Information Systems (GIS) have also achieved a more mature level. However, the linkage between integrate-information management and GIS has not received much attention. The aid of spatial information usually needed when users reading text data files. With the help of spatial information, the knowledge behind the text files can be delivered easier. For information demand side, the concentration of text information can provide plenty and diverse knowledge to users. Besides, the forming of knowledge usually happened when exist knowledge has been linked with related information. For the supply side, one of the key points is how to induce the needs of GIS when users are using text-based system. This study evaluates the linking GIS spatial locating and browse function by analyzing the spatial information requirements within the text file. The major purpose is trying to combine spatial and text database.he meanings of the sentences have to be analyzed first and the relationships between words are the priority. Research reports are the primary study targets. The meanings of the sentences are simple but the diversities are large in these kinds of reports. In order to evaluate the spatial meanings in the sentences, the most frequent sentences have been identified first and the structure relationships between words have been summarized in this study. According to the different amounts of spatial and attribute criteria, the possible demands from the users and the corresponding GIS data can be summarized.he database of date description, words, key words and name of location have been built. Meanwhile, the identification of spatial and attribute criteria was used to construct the framework of combining the text files and GIS data. This combinational framework of the text files and GIS data was ready for practical use which can provide users a more convenient “text-figure” reading system. Through this framework, users can link the text file to GIS data and present the information more efficiently. This procedure should be able to satisfy the potential needs of GIS data when users are reading the text files. The related GIS data was provided to give users a more objective guideline rather than only a mental image. By this proposed framework, spatial knowledge can be presented concretely and the traditional text reading would have a dramatic change.
