An Interpretable CF-RL-TOPSIS Fusion Model for Skills-Aware Talent Recommendation

  • 融合协同过滤、强化学习与TOPSIS三类算法,动态加权决策
  • 在JobHop数据集上达到NDCG@5=0.3040,显著优于多种基线
  • 支持逐项可解释,适合需要透明推荐的招聘场景

有效的技能感知人才推荐需平衡行为转移模式、轨迹敏感适应与可解释的职业层级标准。然而,这些信号如何交互仍缺乏公开基准证据。本文提出CF-RL-TOPSIS,一种可解释的晚期融合模型,整合了面向转移的协同分支、紧凑型强化风格职业族带宽代理,以及基于六个语义代理构建的熵权重TOPSIS分支;验证选定的融合系数保持可审计性。模型在两个冻结的公开ICT人才历史基准(JobHop和Karrierewege)上评估,采用重复时间序列前5名排名和配对威尔科克斯检验。在JobHop上,完整混合模型达到NDCG@5 = 0.3040 ± 0.0073,显著优于重复最后、物品马尔可夫、转移感知协同过滤、CF+TOPSIS混合、GRU4Rec和SASRec(计划比较中p ≤ 0.0039)。在Karrierewege上,混合模型仍具竞争力但未显著超越最强马尔可夫基线,揭示出以持续性为主导的环境,此时带宽分支权重趋近零。代理敏感性、族级深度Q网络及运行时检查支持该解释,且通过用户级案例展示了分支得分、准则权重与排序变化的可追溯性。贡献不在于跨基准普适优势,而是在可复现条件下说明透明晚期融合何时优于简单延续启发式。在语义丰富、未饱和的人才历史环境下,三分支相互增强;在持续主导环境中,同一架构仍具竞争力,依赖其协同主干,自适应分支正确处于非激活状态。

原文摘要 · Abstract (English)

Effective skills-aware talent recommendation must balance behavioral transition patterns, trajectory-sensitive adaptation, and inspectable occupation-level criteria. Evidence from public benchmarks on how these signals interact, however, remains limited. This study proposes CF-RL-TOPSIS, an interpretable late-fusion model that integrates a transition-aware collaborative branch, a compact reinforcement-style occupation-family bandit, and an entropy-weighted TOPSIS branch constructed from six semantic proxies; the validation-selected fusion coefficients remain auditable. The model is evaluated on two frozen public ICT talent-history benchmarks, JobHop and Karrierewege, using repeated chronological top-5 ranking and paired Wilcoxon tests. On JobHop the full hybrid attains NDCG@5 = 0.3040 +/- 0.0073 and significantly surpasses repeat-last, item Markov, transition-aware collaborative filtering, the CF+TOPSIS hybrid, GRU4Rec, and SASRec (p <= 0.0039 across planned comparisons). On Karrierewege the hybrid remains competitive but does not significantly exceed the strongest Markov baseline, revealing a persistence-dominated setting in which the bandit branch appropriately shrinks to near-zero weight. Proxy-sensitivity, family-level deep Q-network, and runtime checks support this interpretation, and a worked user-level case shows how branch scores, criterion weights, and rank shifts can be inspected for an individual recommendation. The contribution is not a benchmark-agnostic superiority claim, but a reproducible account of the conditions under which transparent late fusion adds value beyond simple continuation heuristics. In semantically rich, non-saturating talent-history regimes the three branches reinforce one another; in persistence-dominated regimes the same architecture remains competitive through its collaborative backbone, with the adaptive branch correctly inactive.
