AIn a search for lessons learned from 50 years of history of AI, this paper presents a brief, subjective and personal history of the field. It then introduces five theses-prescriptions for what makes good AI research. The theses stem form the author's understanding of successes and failures of the field, and from his own experience as a long-standing and active member of the AI community. The five theses promote practicality, embeddedness, empirical verification, mathematical foundation, and scrutiny.

This article treats about modeling different phenomena by means of concepts and tools elaborated in the computer science framework, mainly in that of Artificial Intelligence (AI). After having presented the notion of formalized computer science model (CSMd), we described general interactive modeling procedure (which consists of four stages: abstraction, formalization, simplification and verification). Then we characterize this procedure in the context limited to computer science. While discussing different types of CSMd, we focus on the domain of AI, e.g. we distinguish between rule-based models (often implemented as expert systems), network-based models (often implemented as artificial neural networks) and evolutionary models (often based using genetic algorithms). But, most importantly, we believe that machine learning tools (as part of the AI domain) could and, as the matter of fact, should be used in order to automate each of the stages of the proposed interactive modeling procedure.

This paper presents the construction of the ProfileSEEKER – the information system for early warning small and medium-sized enterprises from bankruptcy. The developed system is a set of five classifiers, using a variety of topologies of artificial neural net-works and Bayes belief network, supported by supervised machine learning methods. System performance was evaluated using the original validation, called queue validation procedure.

This paper presents an attempt to apply advanced computational methods to a database of Old Kingdom Egyptian copper model tools. We examine a particular class of artefacts, chisels. A smaller dataset extracted from them was used to train several linear and non-linear classification models. All these models were able to classify the items according to their origin, the site or part of site where they were found. The origin of the chisels was set against a working hypothesis in an attempt to establish the provenance of some chisels, presumably ones coming from excavations by Hermann Junker at Giza, currently in the collection of the Kunsthistorisches Museum in Vienna. The classification model has corroborated the indications of other contextual information, and the tentative provenance of the assemblages in the Western Field at Giza is proposed. Another set of predictions was influenced by fragments of chisels, particularly those described in the database from Abusir South, which skewed the predictions of other fragmentary pieces towards this site.

Determinants of economic development in different countries are analyzed in the paper. According to the literature, the analyses of variables and factors underlying the different pace of economic growth in different countries reveal the complexity of processes driving different countries towards higher level of economic development. In the article the degree of dependencies between the level of economic development and various attributes including macroeconomic factors and human capital is measured in the years 1965 - 2003. Comparative analysis of World Development Indicators database published yearly by the World Bank is conducted on values of 695 attributes in 208 countries. The occurrence of missing data, motivated to use a set of tools for data exploration WEKA (Waikato Environment for Knowledge Analysis). Thus in addition, the problem of the applicability of data exploration tools for analyzing real data arising from economic processes was investigated.

In this paper an attempt to verify, whether the empirical data confirm the welfare determinants suggested in economic literature, like e.g. educational, geographical, behavioural features of the individual and his/her parents, see e.g. Wedgwood (1928). The analysis is conducted using machine learning tools and then the obtained results are compared with other studies. To ensure the possibility of such assessment the capability of interpretation in terms of natural language is needed and thus the knowledge in the form of classification rules is presented.
