StJds (StJd table)

A table (file) stores the testing data set (4000 MEDLINE Journals, 1.3M records) of JD scores for each ST based on:

• word frequency count
• document count for word
This file is pre-generated, read in, loaded into RAM, and then used to perform ST indexing (real-time) on text. Currently, this table is generated based on Susanne's data. New programs are to be developed to generate the data from scratch (new test set).
• Description:

  This Java class is to read in St-Jd table from a file and load to a java Object. This java object provides basic method to set and get JD scores for a specified ST.

• Inputs: The format of this file, stJdTable.txt, is:

  ST	JD index	Word scores	Document scores	JD Id	JD Full Name

• Java Files:
  • StJd.java
  • StJds.java

• Algorithm:
  • Read in file and save St-Jd scores into Java objects, StJds.
