Subject Re: Scoring
Date Thu, 15 Jun 2006 00:01:14 GMT

This is a great start.  I have also started a scoring.xml document under 
the xdocs directory (in my sandbox).  So far, I have the following 
sections (some even have content under them!):
1. Introduction  // Intro about Vector Space Model, some references to 
theory, links to the Similarity scoring Formula
2. Scoring and the Index   //How scoring relates to what is in the index 
(i.e. how it takes advantage of precomputed info such as norms, etc.
3. Understanding Similarity  //How the Similarity class fits into 
Scoring and what it means to override the Similarity (Greek Kung Fu!)
4. Changing Your Scoring -- Expert // A discussion of 
overriding/creating Scorer/Query/Whatever else
5. Class Diagrams // Links to your cool pictures
6. Sequence Diagrams //More cool pictures

What else is needed/useful?  Anyone want to volunteer on a section?
