Advances in Web Intelligence

Piotr S. Szczepaniak; Janusz Kacprzyk; Adam Niewiadomski

Web Intelligence (WI) presents excellent opportunities and challenges for the research and development of new generation of Webbased information processing technology, as well as for exploiting Webbased advanced applications. Based on two perspectives of WI research: an intelligent Web-based business-centric schematic diagram and the conceptual levels of WI, we investigates various ways to study WI and potential applications.

On the Relationship Between Active Contours and Contextual Classification

Arkadiusz Tomczyk; Piotr S. Szczepaniak

To discuss the relationship between active contours and contextual classification, a formal definition of the contour as well as a uniform approach to the all active contour methods are proposed first, and then a contextual classification problem is introduced and formalized. The equivalence relationship between contours and classifiers, thoroughly considered and illustrated by examples, proves to allow incorporation of the methods and techniques specific for the active contour approach to the contextual classification and vice versa.

Adaptive potential active hypercontours

Arkadiusz Tomczyk; Piotr S. Szczepaniak

In this paper, the idea of adaptive potential active hypercontours (APAH) as a new method of construction of an optimal classifier is presented. The idea of active hypercontours generalizes the traditional active contour methods, which are extensively developed in image analysis, and allows the application of their concepts in other classification tasks. In the presented implementation of APAH the evolution of the potential hypercontour is controlled by simulated annealing algorithm (SA). The method has been evaluated on the IRIS and MNIST databases and compared with traditional classification techniques.

Notes on a Linguistic Description as the Basis for Automatic Image Understanding

Ryszard Tadeusiewicz; Marek R. Ogiela; Piotr S. Szczepaniak

Notes on a Linguistic Description as the Basis for Automatic Image Understanding The main paradigm of image understanding and a concept for its practical machine realisation are presented. The crucial elements of the presented approach are the formalisation of human knowledge about the class of images that are to be automatically interpreted, a linguistic description and the realization of cognitive resonance.

Classification of RSS-Formatted documents using full text similarity measures

Katarzyna Wegrzyn-Wolska; Piotr S. Szczepaniak

The Web is enormous, unlimited and dynamically changed source of useful and varied kinds of information. The news is one of the most rapidly changing kinds of information. The departure for this paper is presentation of RSS, an useful data format used frequently by publishers of news; some statistics related to news syndication illustrate the actual situation. Then, two recently developed methods for examination of similarity of textual documents are briefly presented. Since RSS-supplied records always contain the same type of information (headlines, links, article summaries, etc.), application of methods of presented type makes their diverse applications like automatic news classification and filtering easier.

Contribution of Active Contour Approach to Image Understanding

Arkadiusz Tomczyk; Piotr S. Szczepaniak

The paper proposes a formal, though a simple, model of the activity of human vision system. That model serves as a reference point for description of relational and contextual recognition and allows to formulate a definition of image understanding problem. As a potential solution of that problem active contour methods are proposed, which do not possess some limitations of classic recognition algorithms. Moreover, they can be used not only as methods of construction of contextual pixel classifiers, but also as methods of identification of relations between any arbitrary more complicated structures (concepts).

Active contours as knowledge discovery methods

Arkadiusz Tomczyk; Piotr S. Szczepaniak; Michal Pryczek

In the paper we show that active contour methods can be interpreted as knowledge discovery methods. Application area is not restricted only to image segmentation, but it covers also classification of any other objects, even objects of higher granulation. Additional power of the presented method is that expert knowledge of almost any type can be used to classifier construction, which is not always possible in case of classic techniques. Moreover, the method introduced by the authors, earlier used only for supervised classification, is here applied in an unsupervised case (clustering) and examined on examples.
