  • On the need to bootstrap ontology learning with extraction grammar learning  
  • by Georgios Paliouras — In Conceptual Structures: Common Semantics for Sharing Knowledge, 13th International Conference on Conceptual Structures (2005
  • …Abstract. The main claim of this paper is that machine learning can help integrate the construction of ontologies and extraction grammars and lead us closer to the Semantic Web vision. The proposed approach is a bootstrapping process that combines ontology and grammar learning, in order to semi-auto…

  • Ion Androutsopoulos  
  • by Aris Kosmopoulos, Georgios Paliouras
  • …In the past few years, machine learning and in particular simple Naive Bayes classifiers have proven their value in filtering spam emails. We hereby put Naive Bayes filters to the test, against potentially more elaborate spam filters that will participate in the ceas 2008 challenge. For this purpose…

  • The Effect of Numeric Features on the Scalability of Inductive Learning Programs  
  • by Georgios Paliouras, David S. Bree — 1995 — In Proceedings of the European Conference in Machine Learning
  • …The behaviour of a learning program as the quantity of data is increased affects to a large extent its applicability on real-world problems. This paper presents the results of a theoretical and experimental investigation of the scalability of four well-known empirical concept-learning programs. In p…

  • Learning user communities for improving the services of information providers  
  • by Georgios Paliouras, Christos Papatheodorou, Vangelis Karkaletsis, Costantine Spyropoulos, Victoria Malaveta — 1998 — In European Conference on Research and Advanced Technology for Digital Libraries
  • …Abstract. In this paper we propose a methodology for organising the users of an information providing system into groups with common interests (communities). The communities are built using unsupervised learning techniques on data collected from the users (user models). We examine a system that filt…
