Advanced queries that combine spatial constraints with textual relevance to retrieve objects of interest have attracted increased attention recently due to the ever-increasing rate of user-generated spatio-textual data. Motivated by this trend, in this paper, we study the novel problem of parallel and distributed processing of spatial preference queries using keywords, where the input data is s...

Denoising filters are useful for reducing noise; however, they often blur and smear the edges and boundaries, which are necessary for segmenting or locating the objects. In order to overcome above problem, many filters with contrast enhancement capability have been developed, and they have wide applications in related fields. Recently, researchers found that the traditional criteria, such as me...

When a multidatabase system contains textual database systems (i.e., information retrieval systems), queries against the global schema of the multidatabase system may contain a new type of joins-joins between attributes ol textual type. Three algorithms for processing such a type of joins are presented and their l/O costs are analyzed in this paper. Since such a type of joins often involves doc...

This paper presents a methodology for the enhancement of a hypertext version of a textbook. The enhancement over the textual version of the textbook is achieved by automatically inserting links between text excerpt of the textbook and item in the subject index produced by the author of the textbook. These links enable accessing parts of the textbook that have not been speci cally indexed by the...
