Alissa Cooper
A Policy Perspective on Query Log Privacy-Enhancing Techniques

Abstract:
As popular search engines face the sometimes conflicting interests of protecting privacy while retaining query logs for a variety of uses, numerous technical measures have been suggested to both enhance privacy and preserve at least a portion of the utility of query logs. This article seeks to assess seven of these techniques against three sets of criteria: (1) how well the technique protects privacy, (2) how well the technique preserves the utility of the query logs, and (3) how well the technique might be implemented as a user control. A user control is defined as a mechanism that allows individual Internet users to choose to have the technique applied to their own query logs.

Bio:
Alissa Cooper is the Chief Computer Scientist at the Center for Democracy and Technology. Her work focuses on a range of issues including consumer privacy, spyware, digital copyright, network neutrality, and identity management. She conducts research into the inner workings of common and emerging Internet technologies, and seeks to explain complex technical concepts in understandable terms. She has testified before Congress and the Federal Trade Commission and writes regularly on a variety of technology policy topics.
Alissa moved to the Washington area after completing her Bachelor's and Master's degrees in Computer Science at Stanford University. There her work focused on computer security issues and their policy implications.

Workshop Overview

This workshop is a forum for new research relating to Web search usage logs and for discussing desirable properties of publicly released search log datasets.

Topics of interest include but are not restricted to:

  • web mining
  • information retrieval
  • learning to rank
  • desiderata for future click data releases
  • mining semantic relationships, for example within and between the query set and document set
  • analysis and correction of biases in the data
  • clustering/grouping log data by: topic, task, geographic location, time.
  • generative models for the log events, query text and/or document text
  • other tasks which can be improved with the click data

Research relating to search logs has been hampered by the limited availability of click datasets. During the first phase, participants who submitted a proposal and were selected got access to the free Microsoft 2006 RFP dataset upon signing a license agreement.

Authors are invited to submit papers using this or other datasets.

Activities: Presentations & Poster session.

Important Dates

  • Proposals: Wednesday, September 3, 2008
  • Response to proposals: Wednesday, September 10, 2008
  • Paper submission: December 5, 2008
  • Paper notification: December 29, 2008 (Note: Date changed)
  • Camera ready: January 5 (Note: Date changed to allow time for processing by ACM Digital Library)
  • Workshop: February 9

The Shared Dataset

Based on proposals in September 2008, some workshop participants were granted access to a shared dataset. It is a MSN Search query Log excerpt (RFP 2006 dataset):

  • 15 million queries
  • Sampled over one month
  • Queries from the US site (mostly English)

Per query attributes included:

  1. Session ID
  2. Time-stamp
  3. Query string
  4. Number of results on results page
  5. Results page number

Data per query for each result clicked:

  1. URL
  2. Associated query
  3. Position on results page
  4. Time-stamp

Due to the type of assets under consideration, the principal investigator was asked to sign a data licensing agreement before accessing the data. The terms of the license will allow for publication of results but restricts redistribution of the data and publication of detailed excerpts of the data.
