Collaborative Information Seeking Lab Experiments Dataset

Rutgers University announces the availability of the Collaborative Information Seeking Lab Experiments Dataset. The data are from a set of lab experiments conducted by Chirag Shah and Roberto Gonzalez-Ibanez at Rutgers University in 2010-2011. It contains interaction logs (queries, page visits, relevance judgments, and snippets collected) by a total of 160 participants in 80 teams, with each team working on an exploratory search task for about 30 minutes in a controlled lab setting. The data were collected using Coagmento ( The dataset can be downloaded from
Following is a small selection of papers that use the data that one can cite.

Note that this dataset is also being used for the Second International Workshop on the Evaluation on Collaborative Information Seeking and Retrieval (ECol) to be held at the ACM CHIIR 2017 conference in Oslo, Norway on March 11, 2017. More details are here:

They hope this dataset, which took months to collect, would be a useful resource to researchers working in the fields of interactive IR, as well as social/collaborative search.
