A relevance management system for managing relevance of a plurality of request for proposal (RFP) documents with respect to a plurality of project description (PD) documents; receiving a PD document; creating a PD-document decomposition by decomposing the PD document into PD segments; determining an RFP-document-to-PD-segment relevance for an RFP document from the plurality of RFP documents and the PD segments using document similarity processing and a metric; aggregating the RFP-document-to-PD-segment relevance by the PD-document decomposition to produce an RFP-to-PD relevance; and transmitting the RFP-to-PD relevance to an originator of the PD document.
