  • Survey Conclusions• Google is the dominant search engine• This has two consequences 1. People compare other search systems to their experience with Google 2. The search task is mainly performed by using keywords PoliMedia symposium: User research in the 6 development of PoliMedia
  • Interviews• N=5• Quantitative (n=2) as well as qualitative (n=4)• Main themes – How do people search currently? – What could be improved about current search systems? – What should PoliMedia offer, given its goals?• Results – 39 user wishes – Prioritized internally • 19 user wishes deemed out of scope • 20 user requirements PoliMedia symposium: User research in the 7 development of PoliMedia
  • Interviews Findings• Key issue is to provide a good overview of data – Why are search results retrieved – How are search results ranked• Assumptions of relevance – Higher frequency of keywords indicated higher relevancy to query? – Longer segments (speeches and articles) indicate higher importance?• Many more or less out-of-scope wishes to make current research easier – Sentiment-metadata – Context metadata • Roles of people • Links to external databases • Types of documents • Types of presentation (dramatic, humoristic, etc.) – Ability to export to own software PoliMedia symposium: User research in the 8 development of PoliMedia
