Bluemix NL Classifier Tutorial

  1. 1. Configuring the Classifier on IBM Bluemix craigtrim@gmail.com
  2. 2. QUESTION TYPE CLASSIFICATION DATA PREPARATION ... Part 1
  3. 3. 1. Verification: invites a yes or no answer. 2. Disjunctive: Is X, Y, or Z the case? 3. Concept completion: Who? What? When? Where? 4. Example: What is an example of X? 5. Feature specification: What are the properties of X? 6. Quantification: How much? How many? 7. Definition: What does X mean? 8. Comparison: How is X similar to Y? 9. Interpretation: What is the significance of X? 10. Causal antecedent: Why/how did X occur? 11. Causal consequence: What next? What if? 12. Goal orientation: Why did an agent do X? 13. Instrumental/procedural: How did an agent do X? 14. Enablement: What enabled X to occur? 15. Expectation: Why didn't X occur? 16. Judgmental: What do you think of X?  Questions are often generated by a person's knowledge deficits and cognitive disequilibrium, which occurs when there are obstacles to goals, contradictions, impasses during problem solving, anomalous information, and uncertainty. Question Types
  4. 4. A total of 5 points are distributed for each question Questions are gathered from public domain sources off the internet Point distribution is manual Classification
  5. 5. Python script to take CSV formatted data from Excel Spreadsheet Creates a CSV file that the NL Classifier can understand Classification

  25. 25. TRAINING A CLASSIFIER IN 5 SIMPLE STEPS ... Part 3
  26. 26. Step 1: Train a Classifier (Slide 1)
  27. 27. Step 1: Train a Classifier (Slide 2)
  28. 28. Step 2: Prepare the Data (Slide 1)
  29. 29. Format • The data format is: text,class • The text is the actual question or user statement; some real world example • The class is the classification of this real world example – Only [A-Za-z0-9] are permitted – Use “myClassName” rather than “my_class_name” • The text and the class are comma separated, with the text occurring first Example what is the difference between being alive and truly living?,comparison "when is it time to stop calculating risk and rewards and just go ahead and do what you know is right?”,conceptCompletion "when is it time to stop calculating risk and rewards and just go ahead and do what you know is right?”,interpretation "if we learn from our mistakes why are we always so afraid to make a mistake?”,enablement Step 2: Prepare the Data (Slide 2)
