Abstract

The iTrust system is a decentralized and distributed system for publication, search and retrieval of information over the Internet and the Web, that is designed to make it difficult to censor or filter information. In the distributed ranking algorithm for iTrust presented in this paper, a source node that publishes a document indexes the words in the document and produces a term-frequency table for the document. A requesting node that issues a query and receives a response uses the URL in the response to retrieve the term-frequency table from the source node. The requesting node then uses the term-frequency tables from multiple source nodes and a ranking formula to score the documents with respect to its query. Our evaluations of the distributed ranking algorithm for iTrust demonstrate that the algorithm exhibits stability in ranking documents and that it counters scamming by malicious nodes.
