Report on the First Workshop on Supporting Complex Search Tasks

Abstract

There is broad consensus in the field of IR that search is complex in many use cases and applications, both on theWeb and in domain specific collections, and both in our professional and in our daily life. Yet our understanding of complex search tasks, in comparison to simple look up tasks, is fragmented at best. The workshop addressed many open research questions: What are the obvious use cases and applications of complex search? What are essential features of work tasks and search tasks to take into account? And how do these evolve over time? With a multitude of information, varying from introductory to specialized, and from authoritative to speculative or opinionated, when to show what sources of information? How does the information seeking process evolve and what are relevant differences between different stages? With complex task and search process management, blending searching, browsing, and recommendations, and supporting exploratory search to sensemaking and analytics, UI and UX design pose an overconstrained challenge. How do we know that our approach is any good? Supporting complex search tasks requires new collaborations across the whole field of IR, and the proposed workshop brought together a diverse group of researchers to work together on one of the greatest challenges of our field.

The workshop featured three main elements. First, a keynote on an emerging theory of task difficulty by Diane Kelly. Second, a lively boaster and poster session in which seven contributed papers were presented. Third, three breakout groups on: 1) user interfaces and user experience, 2) tasks and users, and 3) information needs on controversial topics. There was an general feeling that the discussion made progress, and built new connections between related strands of research in IR.
