What information is in the DXplain database?

The average disease description includes 53 findings (with a range of from 10 to over 100). Each disease/finding pair has two numbers describing the relationship, one representing the frequency with which the finding occurs in the disease and the other the degree to which the presence of the finding suggests consideration of the disease. There are over 230,000 individual data points in the KB representing disease/finding relationships. In addition, each finding has an associated disease-independent importance attribute from 1 to 5 indicating how important it is to explain the presence of the finding.
