Abstract: There are provided a system, a method and a computer program product for increasing of productivity of sales force in a first entity. The system locates or constructs at least one enterprise social network in the first entity. The system constructs at least one market social network. The system creates at least one connection between the enterprise social network and the market social network. Sales representative in the first entity expands new sales operations and/or identify new markets via the connected social networks.

Abstract: A system, method and computer program product automatically present at least one product to at least one client for at least one possible purchase. The system applies a matrix factorization on a binary matrix X representing which clients purchased which products. The system optimizes zero-valued elements in the matrix X that correspond to unknown client-product affinities. The system constructs based on the optimization, a prediction matrix {circumflex over (X)} whose each element value represents a likelihood that a corresponding client purchases a corresponding product. The system identifies at least one client-product pair with the highest value in the matrix {circumflex over (X)}. The system recommends at least one product to at least one client according to the client-product pair with the highest value.
