Technical report TR05-16. We present a concise and accurate structural summary of XML documents and show that this summary can be used to effectively cluster documents that belong to a structurally similar class. We present efficient formulations of similarity between structural summaries that

Technical report TR92-14. Object-oriented computing is influencing many areas of computer science including software engineering, user interfaces, operating systems, programming languages and database systems. The appeal of object-orientation is attributed to its higher levels of abstraction for

standardization efforts are underway. This report presents the TIGUKAT(*) object model definition that is the result of an investigation of object-oriented modeling features which are common among earlier proposals, along with some distinctive qualities that extend the power and expressibility of this model

beyond others. The literature recognizes two perspectives of an object model: the structural view and the behavioral view. Most object-oriented formalisms have concentrated on one or the other of these two perceptions. The TIGUKAT object model (i) favors formal specifications for both the behavioral and

Technical report TR99-03. The use of on-line image repositories is growing and becoming commonplace. Due to the inadequacy of traditional databases in handling complex images and voluminous data, new designs and techniques are needed to efficiently organize, store, manage and retrieve images. It is

felt that the Structural Query Language (SQL) and Object Query Language (OQL) lack the expressive power to describe image queries. Recently the Multimedia Object Query Language (MOQL) which is an extended version of OQL was defined in a PhD thesis at the University of Alberta. As part of the DISIMA

(Distributed Image Database Management System) project, one goal of this report is to design and implement a content-based generic type system to support the storage and retrieval of images. The other goal is to design and implement a query parser and engine for the MOQL extension. There has been research

Technical report TR07-09. The objective of this paper is to explore the relationship between the engineering of Service-Oriented Applications and some strategic and economic concerns of the organizations that (consider to) adopt this architecture style for the development of their software systems

evolution scenarios, and (d) we outline a novel model for estimating the ROI of such evolution scenarios. This work rests squarely within the newly articulated area of \"Service Science, Management, and Engineering (SSME)\" as an \"interdisciplinary approach to the study, design, and implementation of

Technical report TR09-02. The significant increase in open access digital information has created incredible opportunities for modern database research, especially in exploiting significant computational resources to determine complex relationships within those data. In this paper, we consider the

relationships amongst partial tuples of relational databases that would otherwise be hard to expose. We focus on a shortcoming of the absence of a special kind of relationship, which we call \"returning relationship\". We demonstrate our ideas on the DBLP database, where we exploit structural variations on

relationships between authors, conferences, topics, and co-authorships. We show how a distinction between normal relations and returning relations on objects within that database provides the basis for structuring a random walk algorithm to determine interesting relevance measures. We also show how structural

Technical report TR03-19. In most engineering disciplines, it is assumed that the education of their professionals involves an apprenticeship component, in addition to their formal training. This is why most undegraduate software-engineering programs involve a capstone project course, where

Technical report TR06-09. This paper presents a new technique, called aura 3D textures, for generating solid textures based on input examples. Our method is fully automatic and requires no user interactions in the process. Given an input texture sample, our method first creates its aura matrix

the evaluation results using human subjects, we conclude that our algorithm can generate faithful results of both stochastic and structural textures with an average successful rate of 76.4%. Our experimental results also show that the new method outperforms Wei & Levoy's method and is comparable to
