  1. The 5 W’s of Collaborative Search Jaime Teevan and Merrie Morris Microsoft Research

  2. Who, What, Where, When & Why? • Who does collaborative searches? • Whatare collaborative search tasks? • Whereare the collaborators located? • Whendoes the collaboration occur? • Why do people collaborate? • How can we support collaborative search? Understand Frame

  3. Who Does Collaborative Searches? • Everyone! • More than 50% report collaborating for search • People rely on others even for individual search • Consider type of relationship • Privacy considerations • Friends v. strangers • Kids v. adults

  4. WhatAre Collaborative Search Tasks? • Tend to be involved tasks (v. directed search) • Some popular tasks: • Travel planning • Shopping • Technical information/literature • Important: Important task be related to group • Work groups get benefit for work tasks • Social groups get benefit for social tasks

  5. WhereAre the Collaborators Located? • Co-located • Ability to share control • Ability to partition task: Smart Splitting • Remote • Awareness of others important Type 2 Diabetes Complications- American Diabetes Association Many of the complications of diabetes are strongly related to high blood sugar levels. It is believed that keeping your blood sugar levels in your target range is your best defense ... www.diabetes.org/type-2-diabetes/complications.jsp Type 2 Diabetes Complications- American Diabetes Association Many of the complications of diabetes are strongly related to high blood sugar levels.

  6. WhenDoes the Collaboration Occur? • Synchronous • Communication important • Support different roles • Asynchronous • Need to preserve and expose state • Hard to identify future value of information • Can “collaborate” with future self

  7. WhyDo People Collaborate? • Group identification • Explicit • Implicit • Group longevity • Task-based • Trait-based Task Friends Age Gender Job team Identification Implicit Explicit Job role Location Relevance judgments Query selection Interest group Task-based Trait-based Longevity

  8. How Can We Support Collaboration? • Group identification • Match people into groups • Match task to appropriate group • Algorithmic support for collaborative search • Identify documents of interest to group • Partition information appropriately to members • Summarize documents based on group interests

  9. How Can We Support Collaboration? • Build a common evaluation framework • An example framework • Individual profiles • Grouping information • Relevance judgments for common queries • We have used the framework to study • Groupization • Smart splitting • Group hit highlighting
