Towards Privacy Preserving Information Retrieval through Semantic Microaggregation
Daniel Abril, Guillermo Navarro‐Arribas, Vicenç Torra · 2010
In this paper we introduce the problem of providing privacy preserving information for Web indexing, classification, and other information retrieval task. Web pages are represented by a frequency term vector that preserves k-anonymity for all the Web pages. This vector can then be used, for example, to build indexes of classifiers. Our proposal makes use of semantic micro aggregation.
