This paper formalizes UML class diagrams and structural patterns as mathematical objects and provides a precise notion of conformance of a structural model specified as a class diagram to a structural pattern. We also present a conformance verification method which represents a class diagram as a logic program and a structural pattern as a query. The conformance of the class diagram to the stru...

Design patterns may introduce a new perspective on the traditional subject of data structures. They introduce more flexibility and reusability in data structures implementation and use. This analysis shows that design patterns could bring important advantages in basic fields of Computer Science, too. Beside the advantages brought for data structures, presenting them in this perspective represen...

Computer software for academic research (e.g. DRAIN2D) is often deficient in Graphical User Interface (GUI) and commercial software doesn’t open GUI’s framework to the user. The advantage of GUI is so evident and the requirements of GUI always exist. Thus, there exist sufficient reasons to research on the GUI’s framework. This article introduces that how to build an extensible and flexible GUI ...

We propose a new method of extracting texts related to a given keyword from Web pages collected by a search engine. By combining structural pattern matching and text classification, texts related to a given keyword such as reputations of a given restaurant can be extracted automatically from Web pages in unfixed sites, which is impossible by conventional wrappers. According to our cross validat...

This paper presents a probabilistic similarity measure for object recognition from large libraries of line-patterns. We commence from a structural pattern representation which uses a nearest neighbour graph to establish the adjacency of line-segments. Associated with each pair of line-segments connected in this way is a vector of Euclidean invariant relative angle and distance ratio attributes....

This paper describes new temporal data mining techniques for extracting information from temporal health records consisting of time series of diabetic patients’ treatments. In this new method, there are three steps for analyzing patterns from a longitudinal data set. The first step, a structural-based pattern search, to find qualitative patterns (or, structural patterns). The second step perfor...

This thesis aims at investigating a new approach to document analysis based on the idea of structural patterns in XML vocabularies. My work is founded on the belief that authors do naturally converge to a reasonable use of markup languages and that extreme, yet valid instances are rare and limited. Actual documents, therefore, may be used to derive classes of elements (patterns) persisting acro...
