  ASIST: Studies of Searching Behaviors
Studies of Searching Behaviors
Wednesday, November 2, 2005 8:30am

Dick Stenmark, Searching the Intranet
Intranets differ from public web (Fagin et al 2003).  They’re growing (size, number, importance)

Method:  a la Spink et al 2001, sessions spanned multiple days (definition of session not trivial)
Session definition (type a: related activities in different sessions , type b: unrelated activities together) – idle time set as 13 minutes.  They played with different thresholds first.

61% of users – one activity per session (backs up the open internet idea that users aren’t refining their searches or viewing multiple pages of results) Maximum session length 1 hour.
69.2% one word querys-- avg 1.4 words/query
90% users didn’t go beyond the first page (10 results)

Conclusions:  

Future
Questions from the audience:  

Sherry Koshman, Repeat visits to Vivisimo
Information problem > time > search episodes
How often do people return?  What are the characteristics of repeated sessions
68% of users made repeat visits, weekday searching higher number of sessions
Jihyun Kim, Finding Documents in a Digital Institutional Repository
Looked at archives in DSpace and Eprints, compared 2 commonly used open access institutional repository software packages

Looked at Australian National University, which has both interfaces for the same sets of documents
From Heuristics
Dspace is better – more simplified search forms which were preferred.
Eprints is better – minimizig the user’s memory load

Recommendations
Three box search forms were preferred in each
Provide examples of search queries
List search results in a useful way
Useful components displayed per result
Clearly present a link to open the full text
