A Hierarchical Optimizer for Recommendation System Based on Shortest Path Algorithm (1911.08994v1)
Published 7 Nov 2019 in cs.SI and cs.IR
Abstract: Top-k Nearest Geosocial Keyword (T-kNGK) query on geosocial network is defined to give users k recommendations based on some keywords and designated spatial range, and can be realized by shortest path algorithms. However, shortest path algorithm cannot provide convincing recommendations, so we design a hierarchical optimizer consisting of classifiers and a constant optimizer to optimize the result by some features of the service providers.
