1. A computer system for computing an interest score for one or more contacts of a research entity that produces research work product items that individually cover one or more of a plurality of topics, wherein the topics comprise at least one of publicly-traded stocks, industries, and geographic regions, wherein the one or more contacts are associated with accounts for holding and trading publicly-traded securities, and wherein the research entity comprises a plurality of teams that produce the research work product items, the computer system comprising: a computer-based data storage system that stores data relating to the contacts and the research work product items produced by the entity; at least one processor in communication with the computer-based data storage system; and at least one computer memory device in communication with the processor, wherein the at least one computer memory device stores instructions that when executed by the at least one processor causes the at least one processor to compute a work product item interest scores for the one or more contacts for one or more work product items produced by the research entity, wherein the work product item interest score for a particular contact and a particular work product item is indicative of the particular contact's likely interest in the particular work product item, wherein the at least one processor is programmed to compute the work product item interest scores by performing steps comprising: determining for the one or more contacts at least one of the following sub-interest scores: a stock sub-interest score for one or more of the stocks, wherein the stock sub-interest score for a stock for a contact is a score indicative of the contact's interest in accessing research pertaining to the stock; and a team sub-interest score for one or more analyst teams of the research entity, wherein the team sub-interest score for an analyst team for a contact is a score indicative of the contact's interest in accessing research from the analyst team; wherein the sub-interest scores are determined using one or more mathematical models, wherein the one or more mathematical models uses a plurality of derived variables that are indicative of the one or more contacts' interest in the stocks and/or analyst teams, wherein the plurality of derived variables comprise at least one of the following derived variable: a first derived variable that is based on data regarding the research work product items produced by the entity that were accessed by the one or more contacts; a second derived variable that is based on data regarding communication interactions between the one or more contacts and the teams of the research entity; a third derived variable that is based on broker votes by the one or more contacts; a fourth derived variable that is based on stock trades of the accounts associated with the one or more contacts; and a fifth derived variable that is based on stock holdings of the accounts associated with the one or more contacts; computing the work product interest scores for the one or more contacts for work product items produced by the entity, wherein the work product interest score for one contact for one work product item is computed by summing a plurality of weighted summands, wherein the plurality of weighted summands comprise the at least one of the: the stock sub-interest score for the contact for the one or more stocks to which the work product item pertains; and the team sub-interest score for the contact for the team that generated the work product item, wherein: data indicating the one or more stocks covered by each research work product item produced by the research entity are stored in the computer-based data storage system; and data indicating which team produced each research work product item produced by the research entity are stored in the computer-based data storage system, and wherein the work product interest scores are for use by the research entity in notifying the one or more contacts about the work product items.
