Another week of new info. Wouldn't it be great if someone wrote a textbook to include all of these methodologies? I agree with what others have posted. Dr. Gonzalez is an enthusiastic lecturer and her classroom integration is good reinforcement. Still, I need to do some searches to really comprehend the topic. I do know that Precision = TP/TP + FP, and as was debated in class, this is the same as predictive value. Likewise, Recall = TP/TP + FN which is the same as sensitivity.
Text mining is the discipline where patterns are extracted from natural language text (not structured data bases). Althought new to me, this appears to be a discipline studied for years. I found that scientists have hypothesized causes of rare disease by looking for indirect links in different subsets of the bioscience literature for years. I have read in numerous articles that text mining is believed to be extremely useful in the field of biomedicine. Guess that's why it's been presented to us.
Happy Halloween!!!! Lee
