The stages and tasks of
development
1) Preparation, development of editor, search application, and GUI
(4 months)

connection structure of meaning centers (12 months)
Increasing the number of meaning centers
Increasing the number of connections
3) Application to Web searching (6 months)
Putting in context by „neighboring” meaning centers (Which types of links are
useful?)
Query expression (Which combination of operators is the most productive?)
Analysis of hits (How much have the hits become less numerous and more
relevant?)
