Research output: Contribution to journalArticlepeer-review


A general framework allowing prediction of consumer preferences from a knowledge network was described. The method was based on reconstruction of individual tastes of customers from a sparsely connected network of their opinions on products, services or each other. A Gaussian model was used to study the formation of customer opinions. The prediction power was shown to depend on the ratio between the known and unknown opinions.
