In the current age the discovery of relevant information is becoming extremely difficult. Users must manually search through the high-recall, low-precision results produced by current search engines. We propose a process which incorporates benefits of automated and manual information extraction. The HSC workbench (Hierarchical Step-wise Categorization) is a tool developed by the Hewlett-Packard Research Group in HP, ESC Galway. It implements this process supporting the user in information filtering tasks, automating segments of the process but giving the user control of the categorization.
