  • J. Szymański

  - Rok 2017

  The paper presents a new classification schema of IaaS cloud workloads types, based on the functional characteristics. We show the results of an experiment of automatic categorization performed with different benchmarks that represent particular workload types. Monitoring of resource utilization allowed us to construct workload models that can be processed with machine learning algorithms. The direct connection between the functional...

• Categorization of Wikipedia articles with spectral clustering

  Publikacja

  • J. Szymański

  - LECTURE NOTES IN COMPUTER SCIENCE - Rok 2011

  Abstract. The article reports application of clustering algorithms for creating hierarchical groups withinWikipedia articles.We evaluate three spectral clustering algorithms based on datasets constructed with usage ofWikipedia categories. Selected algorithm has been implemented in the system that categorize Wikipedia search results in the fly.

• Weighted Clustering for Bees Detection on Video Images

  Publikacja

  • J. Szymański
  • J. Dembski

  - Rok 2020

  This work describes a bee detection system to monitor bee colony conditions. The detection process on video images has been divided into 3 stages: determining the regions of interest (ROI) for a given frame, scanning the frame in ROI areas using the DNN-CNN classifier, in order to obtain a confidence of bee occurrence in each window in any position and any scale, and form one detection window from a cloud of windows provided by...

• Clustering Context Items into User Trust Levels

  Publikacja

  • P. Lubomski
  • H. Krawczyk

  - Advances in Intelligent Systems and Computing - Rok 2016

  An innovative trust-based security model for Internet systems is proposed. The TCoRBAC model operates on user profiles built on the history of user with system interaction in conjunction with multi-dimensional context information. There is proposed a method of transforming the high number of possible context value variants into several user trust levels. The transformation implements Hierarchical Agglomerative Clustering strategy....

  - Rok 2016

  The methodology of semantic clustering analysis of customer’s text-opinions collection is developed. The author's version of the mathematical models of formalization and practical realization of short textual messages semantic clustering procedure is proposed, based on the customer’s text-opinions collection Latent Semantic Analysis knowledge extracting method. An algorithm for semantic clustering of the text-opinions is developed,...

• Ontology clustering by directions algorithm to expand ontology queries

  Publikacja

  • A. Kaczmarek

  - Rok 2009

  This paper concerns formulating ontology queries. It describes existing languages in which ontologies can be queried. It focuses on languages which are intended to be easily understood by users who are willing to retrieve information from ontologies. Such a language can be, for example, a type of controlled natural language (CNL). In this paper a novel algorithm called Ontology Clustering by Directions is presented. The algorithm...

• Interactive Query Expansion with the Use of Clustering by Directions Algorithm

  Publikacja

  • A. Kaczmarek

  - IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS - Rok 2011

  This paper concerns Clustering by Directions algorithm. The algorithm introduces a novel approach to interactive query expansion. It is designed to support users of search engines in forming web search queries. When a user executes a query, the algorithm shows potential directions in which the search can be continued. This paper describes the algorithm and it presents an enhancement which reduces the computational complexity of...
