On Monday we pitched our experimental design idea to Haiyi and Max. Our PhD student is away for an HCI conference, so it’s up to us undergrads to present. In our presentation, we explained our plans for our 2x2 study by detailing the variables, the participants, the experimental environment, and the outline of the chatbot script. Haiyi and Max liked some elements of what we had so far, but had many helpful suggestions and steered us in the right direction. So the next day (Tuesday) the 3 of us started writing the more detailed script with the new changes in mind. We felt comfortable with the alterations in the bot’s designs, specifically increasing the difference between the passive and the active bot. For the passive bot, we are continuing to make it act upon mention only. But we are also making it solely informative. It will never prompt user action, but merely react and respond to what the members of the group request of it in the chat room. For the active bot, we are having it be more of a discussion facilitator. For example, it will now suggest conversation structure by making statements like “Let’s start the decision making process by brainstorming”. In addition, the active bot will have a voting feature (by polls) to further support the decision making process.
As for the bot with information on MovieLens profiles versus none, we have changed these variables to personalized recommendations versus non-personalized. This made the script writing process easier, because we could just focus on 2 different scripts. One for active and one for passive, rather than 4 separate scripts for each cell. Additional topics that we discussed were which platform to use for the chatroom and where to get the population of participants for the user study(MTurk, Movielens, or Offline). This is more difficult for us to discuss because we do not have a wide knowledge of how these services operate (etc.). Therefore we have made this week’s task to be researching these options in addition to brainstorming more for the script. To accomplish this, I’ve been trying to read more research literature in addition to reviewing past publications I have found to try to find ‘inspiration’ for the script. I have also been informing myself on services that will help us develop the chatbot/chatroom. The tools I have been reading up on are Wit.ai, IBM Watson Conversation and the Slack bot. On Friday, our PhD student came back from his conference so we worked hard to finalize the details on the script. We spent a few hours writing /re-writing everything. We also discussed the chatbot/chatroom set-up. We are leaning towards using Slack for the chatroom, and utilizing the Slackbot feature to create our movie lens bot for the study. As for participants, we are now looking to gain our population from existing MovieLens users. We’ve made many changes this week. Now it’s up to our meeting on Monday with Haiyi and Max to see if these changes are good, or if we need to make more adjustments. For this weekend, we are going to Minnehaha falls! The group has been wanting to go since the start of the program, but the weather forecasts haven’t been in our favor. But this Saturday it will be clear skies!
