In this chapter the authors discuss an application of an immune-based algorithm for extraction and visualization of clusters structure in large collection of documents. Particularly a hierarchical, topic-sensitive approach is proposed; it appears to

We present a new method of modeling of cluster structure of a document collection and outline an approach to integrate additional knowledge we have about the document collection like prior categorization of some documents or user defined / deduced pr

We investigate the impact of an initialization strategy on the quality of fuzzy-based clustering, applied to creation of maps of text document collection. In particular, we study the effectiveness of bootstrapping as compared to traditional "randomiz

A reliable wireless ad hoc network has to be secured against a selfish behavior. In such a network environment nodes have no incentives to participate actively in packet forwarding. Thus, selfishness is a rational choice for network participants. In

In this paper we present new approach to compression of inverted lists in indexes of information retrieval systems. The technique exploits contextual information obtained from a non-supervised clustering process run on the document collection. A subs

Cooperation enforcement is one of the key issues in ad hoc networks. In this paper we proposes a new strategy driven approach that aims at discouraging selfish behavior among network participants. Each node is using a strategy that defines conditions

As document map creation algorithms like WebSOM are computation- ally expensive, and hardly reconstructible even from the same set of documents, new methodology is urgently needed to allow to construct document maps to han- dle streams of new documen

One of the most vital problems of free-text document processing is the curse of dimensionality. The paper presents a dimensionality reduction algorithm based on informed feature selection. Terms describing the document are based on histogram-like sta
