This document examines user interactions with human-like agents, specifically analyzing conversations with the Korean social chatbot Luda Lee. It discusses the types of dialogues users engage in, including ice-breaking, romantic, and conversations involving hate speech, while considering the authenticity of user intentions. Future research aims to explore self-disclosure and authenticity in user-agent engagements.

3. Background
• Human-like agents
 What is human-like?
• Agents that resemble human
• Agents that make human counterpart feel them as human
 Previous studies on anthropomorphism
• Evaluation on successful dialogue with human-like agents (Radziwill and Benton,
2017)
• How users perceive human-like AI devices (Pelau et al., 2021)
• Offensiveness that users show towards human-like agents (Park et al., 2021)
• Mainly in laboratory condition, based on questionnaires
– How about users' perception and their responses, especially non-lab environment?

5. Our approach
• Thematic coding
 Type of conversation
• Which kind of conversation do users have in their dialogues with the agent?
• The content of dialogues that are displayed
 Purpose of user testing
• Do users talk with the agent with their genuine intention? If not, for which
reason they talk with the agent and display the dialogue?
• The purpose of users' testing towards the agent

6. Our approach
• Dataset
 Dataset source
• Crawled posts from 'Luda Lee Gallery' of DC Inside (Korean Reddit-like
community)
 Crawling
• Only posts with screenshots of the dialogue, from 1 Jan. to 8 Jan., 2021
• From the launching of the service and before the influx of trolls (which resulted
in unexpectedly large amount of posts)
 Filtering
• Manual preprocessing to leave only posts that ‘a dialogue between the user
and the agent’ appears
