Comparison of the digital economy development parameters in the EU countries in the context of bridging the digital divide [PDF]
Problems and Perspectives in Management, 2020 The widespread use of information and communication technologies and subsequent transformations have led to the formation of a digital economy (DE). The European Union, as an international organization, has become the subject of building such an economy,

Word Sense Clustering and Clusterability [PDF]
Computational Linguistics, 2016 Word sense disambiguation and the related field of automated word sense induction traditionally assume that the occurrences of a lemma can be partitioned into senses. But this seems to be a much easier task for some lemmas than others. Our work builds on recent work that proposes describing word meaning in a graded fashion rather than through a strict

UAV-Based Crowd Surveillance in Post COVID-19 Era
IEEE Access, 2021 Since outdoor events are gradually allowed within the current pandemic situation, a close monitoring of the crowd activity is needed to avoid undesired contact and disease transmission. In this context, unmanned aerial vehicles (UAVs) can be occasionally

A survey of kernel and spectral methods for clustering [PDF]
, 2007 Clustering algorithms are a useful tool to explore data structures and have been employed in many disciplines. The focus of this paper is the partitioning clustering problem with a special interest in two recent approaches: kernel and spectral methods ...

Clustering documents with active learning using Wikipedia [PDF]
, 2008 Wikipedia has been applied as a background knowledge base to various text mining problems, but very few attempts have been made to utilize it for document clustering. In this paper we propose to exploit the semantic knowledge in Wikipedia for clustering,

SACOC: A spectral-based ACO clustering algorithm [PDF]
, 2014 The application of ACO-based algorithms in data mining is growing over the last few years and several supervised and unsupervised learning algorithms have been developed using this bio-inspired approach. Most recent works concerning unsupervised learning

THE CHARTS OF CLUSTERIZATION AND NON-EQUILIBRIUM CRYSTALLIZATION OF ALLOYS OF EUTECTICUM TYPE [PDF]
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2013 The charts of clusterization of liquid and its subsequent crystallization are obtained cooling alloys with a limit solubility and without mutual solubility of components. It is shown that the transition from a binary solution of liquid to the solid phase

CLUSTERING VIETNAMESE CONVERSATIONS FROM FACEBOOK PAGE TO BUILD TRAINING DATASET FOR CHATBOT
Jordanian Journal of Computers and Information Technology, 2022 The biggest challenge of building chatbots is training data. The required data must be realistic and large enough to train chatbots. We create a tool to get actual training data from Facebook messenger of a Facebook page.
