  2. Context Mixed Initiative Interactions Explanation/ Help

  3. Example 1 User: How do I initialize a variable ? ………help system looks at his context…….. ….......hmmmmmmm…so he is a new user…has never done any programming before...I have to give him information from scratch System: Do you know how to declare a variable? User: No System: Before initializing a variable, you have to declare it. I will teach you to declare it. I need to know what kind of a variable do you want to initialize. So, can you give me an example of what value will that variable contain? User: 1005 System: This is an integer variable. Thus you have to first declare it using the keyword “int”. Do you know how to name a variable? User: No System: The variable name should start with an alphabet or an underscore followed by alphabets, numbers, ………………

  4. Example 2 User: How do I initialize a variable ? ………help system looks at his context…….. ……..hmmmmmmm…so he is new user for Java Programming language, but he has done C and C++ programming…He must be knowing initialization in C and C++…I don’t have to teach him about naming a variable or declaring a variable…let’s check System: You initialize a variable in Java the same way you do it in C or C++. Do you want more clarification? User: No System: Alright then, continue with your coding, let me know if you need any more help.

  5. Outline • Help System and Human Helpers • Context • MII in Online help

  6. Help System and Human Helper

  7. Help Systems (existing) • Self-sufficient and no human helpers • Content rich and context poor • Example – command-line error prompting online tutoring online documentation

  8. Human Help • Personalized – target the user • Customized – target the help tools • Delivered when needed • Human help typically centers around an indirectly established context

  9. Help System with human • Human-In-The-Loop • Human complements the help system

  10. Context

  11. Context • Localized • Contains – • Knowledge about the user • Inference rules • Concepts • Preference of student (pedagogy,…), helper (time,…), help system • Instantiated plans pertaining to current help request • How do we fill in data in our context?

  12. Mixed Initiative Interaction

  13. Mixed Initiative Interactions • Flexible interaction strategy • Each agent contributes what it does best • Roles reversed, initiative reversed, or work independently • Naturalness in communication • Interactions based on SRL models

  14. MII in Helper’s Assistant (Online Help)

  15. Help Context in HA • Helper’s Assistant • Help context consists of • Question/request • Expected type of response (short answer, explanation, discussion, debugging……) • Corresponding material • Knowledge/Skill levels • Tasks of student • Helper communication (offline, online, just-in-time) • Form of help response (manual or automated)

  16. Helper’s Assistant

  17. Case 1: Helper’s Assistant • System confident 1. Context Help System User 2. Help Human Helper

  18. Case 2: Helper’s Assistant • System asks human for verification User Help System 1. Context 3. Help 2. Verification and Context Human Helper

  19. Case 3: Helper’s Assistant • System has no confidence or very little User Help System 1. Context 2. Context 3. Help Human Helper

  20. MII in Helper’s Assistant • MII for the Help System • Question/request (ask for clarification) • Expected type of response (better help) • Choose the mode for helping (system, helper only, helper verify) (better help) • Helper’s communication (online, offline, just-in-time) (better help) • Corresponding material (clarification) • Knowledge\Skill level (clarification/update)

  21. MII in Helper’s Assistant • MII for user (change his goal) • Question/request (Change whenever user wants) • Expected type of response (short answer, explanation, discussion, debugging……) • Corresponding material • Knowledge/Skill levels • Helper communication (offline, online, just-in-time) • Form of help response (system, helper only, helper verifies)

  22. MII in Helper’s Assistant • MII for helper (better help or clarification) • Question/request (ask for more clarifications) • Expected type of response (short answer, explanation, discussion, debugging……) (answer in a better way using another method of explanation) • Corresponding material (need more material) • Knowledge/Skill levels (ask for more clarifications) • Helper communication (offline, online, just-in-time) (better help using another form of communication) • Form of help response ( system, helper only, helper verifies) (better help)

  23. Problems in MII Helper’s Assistant • Fill in the context information • Use the system and online medium for learning OR update the context everytime you learn something new
