Pre-Process: Word-Jdid-Wc-Dc table

• Description:
  This file includes final scores of Word-Jdid-Wc-Dc for all words in training set (MEDLINE). This file is used as the input file for JDI database.

• Input:
  • wordJdidWcDcGt1.txt
  • jdidDcNFactor.txt
  • wordSignalWcDcGt1.txt

• Procedures & Java files:
  • GenerateWordJdidWcDcTable.java
  • Read and calculate word count and document count scores for all word-Jdid from file and then sent to output file
    • Read total word count and document count for each word-Jdid from wordJdidWcDcGt1.txt
    • Read total (normalized) Wc signal and total Dc for all words from wordSignalWcDcScores.txt
    • Read jdDcNFactor for each Jdid from jdidDcNFactor.txt
    • Calculate word count scores and document count scores for all word-Jdid:
      • word count score = (word count/total normalized Wc signal) * NFactor
      • document count score = (document count/total of Dc) * NFactor
  • Print out Word-Jdid-Wc-Dc scores

• Output file:
  • wordJdidWcDcTable.txt, used in JDI database table
