Achieving Privacy in Publishing Search logs
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2013, Vol 13, Issue 1
Abstract
The “database of intentions,” collects by the search engine companies for the histories of their users search queries. These searchlogs are a gold mine for researchers. The Search engine companies, however, are wary of publishing search logs in order not to disclose sensitive information. In this paper, we are analysing algorithms for publishing frequent queries, keywords and clicks of a search log. Our evaluation includes the applications that use search logs for improving both search experience and search performance, and our results show that the ZEALOUS’ output is sufficient for these applications while achieving strong formal privacy guarantees. We are using two real applications from the information retrieval community: Index caching, as the representative application for search performance, and for the query substitution, as a representative application for search quality. For both applications, the sufficient statistics are histograms of keywords, queries, or query pairs.
