| Abstract: | In human-computer interaction, natural language is important to improve the user experience. An attribute of natural dialogue is vague language, but vague language is hard to interpret for systems as meanings differ per user and context. So, to have a usable system with conversational search, it needs to decipher a user's need by understanding vague language. This can be done by asking the user clarifying questions to probe for more specifications and narrow the scope of their requirements, but what clarifying question should be asked differs per user. An expert user who knows the domain is better at naming the requirements outright than a novice user. That is why this research conducted a qualitative user experiment with novice users. In this experiment, the difference in user experience between open and closed questions was analysed. It was expected that closed questions would be an improvement for novice users due to the added context. From this, the results show that novice users who were asked closed questions felt more confident and more able to answer the questions in comparison to novice users with open questions. |
