Context

Mixed Initiative Interactions

Explanation/ Help

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, ………………

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.

• Help System and Human Helpers
• Context
• MII in Online help

• Self-sufficient and no human helpers
• Content rich and context poor
• Example –

command-line

error prompting

online tutoring

online documentation

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

• Human-In-The-Loop
• Human complements the help system

• 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?

• 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

• 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)

• System confident

Human Helper

• System asks human for verification

Human Helper

• 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)

• 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)

• 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)

• Fill in the context information
• Use the system and online medium for learning OR update the context everytime you learn something new

• Ontologize help context
• Mixed Initiative helper’s assistant
• Evaluate
