The Automated Virtual Laboratory Tool (AVLT) is designed to be an intelligent scientific analysis assistant (SAA) system, dedicated to facilitating analysis and reduction of data collected by spaceborne scientific instruments. Within the SAA, a variety of conventional and artificial-intelligence software tools are integrated into a uniform system architecture. The AVLT interfaces with the user through a sophisticated graphical user interface that is part of the SAA environment. Functions of the AVLT include the following:

  • Understanding the formats of input data files and automatically translating the files into whatever other formats are required for processing by analysis functions provided by users;
  • Providing a graphical workspace, and assistance in using the workspace, wherein scientists can create computational experiments for exploration of data, formation of hypotheses, application of analysis functions, interpretation, and presentation, using concepts that are familiar within the scientists' domains of specialty;
  • Providing a subsystem for planning a multistep analysis process to attain a goal based partly on prior computational experiments or on a priori knowledge;
  • Constructing a knowledge base of data-exploration methods and analysis and interpretation algorithms; and
  • Providing sophisticated graphical-presentation software to assist in visualization of data.
