  2. 2. Interaction Design Concept• Integrated with Mendeley rather than stand-alone system• Simple to use (ease-of-use over control)• Support for direct, dynamic and interactive exploration• Support a wide range of search strategies: • Known Item – find a specific person • Subject – find people in a specific discipline • Keyword – find people with a specific keyword in profiles • Prototype – find people similar to a specific person • Social – find people connected to a specific person • Exploratory - start broad, filter and browse 2
  3. 3. Task-based approach to expertise What kinds of expertise? Applied knowledge Hiring Reputation relative to experience Networking skills Subject knowledge Program Networking skills Committee Multidisciplinarity Reputation Expert 3 Subject knowledge Testimony Experience
  4. 4. Expertise Dimensions EvidenceSubject Knowledge Number of academic publications (of types Book, Book Section, Conference Proceedings, Encyclopedia Article, Journal Article, Thesis)Applied Knowledge Number of publications in all non-academic publication types.Experience Years elapsed since date of first publication.Reputation - Number of readers in same main discipline as author - Publication outlets, ranked by readers - Number of professorial versus non-professorial readers of the user’s publicationsConnectedness - Number of contacts - Number of co-authors per publication - Number of groups joined - Total number of members in groups joinedMulti-disciplinarity - Number of disciplines - Number of Sub Disciplines 4 - Percent of total readers from disciplines other than the author’s
