SASI Project

x5c\f9b
Goal:  Develop a computer-based system to help an analyst (researcher, scholar) collect, structure, and interpret information ("idea processing") and document the results (word processing).z20355l3008x6e36\f9i7I
Early emphasis:  Argumentation structures, knowledge representation, knowledge encoding, and retrieval.z20355l3008x6e36\f9i17I
Current metaphor:  Electronic notetaking  NoteCards.z21167l3008x6e36\f9i19I24bi9BI
Themes:
	allow easy, informal user entry
	support movement from informal to formal structures
	integrate new tools into the environment
	evolve designs through use and experimentation
