Prospects and Challenges in Online Data Mining Experiences of Three-Year Labour Market Monitoring Project

The paper provides reflections on feasibility of online data mining (ODM) and its employment in decision-making and control. Besides reviewing existing works in different domains of Data Mining, we also report experiences from ongoing project dedicated to monitoring labour market with the aid of dedicated intelligent information system. Benefits of ODM include high efficiency, availability of data sources, potential extensiveness of datasets, timeliness and frequency of collection, good validity. Among special considerations we highlight a need for sophisticated tools, programming and maintenance efforts, hardware and network resources, multitude and diversity of data sources, disparity between real world and Internet. Finally, we describe some examples of the intelligent system application, in particular analyzing labour market data for several regions.
