Numerical study of reciprocal recommendation with domain matching

摘要

Reciprocal recommendation is the task of finding preferable matches among users in two distinct groups. Popular examples of reciprocal recommendation include online job recruiting and online dating services. In this paper, we propose a new method of reciprocal recommendation that uses a graph embedding technique. In particular, we use cross-domain matching correlation analysis (CDMCA) as a graph embedding method. In CDMCA, feature vectors in different domains are mapped into a common representation space, and reciprocal recommendation is conducted in the common mapped space. Numerical experiments show that the CDMCA with a similarity-based weighting scheme provides a high-quality reciprocal recommendation.
