A method and
system for managing personnel profile information based on vector indexing is disclosed. The method first converts
project manager profiles into high-dimensional vectors and constructs a vector index, with
data consistency, fairness, and qualification compliance as multi-objective constraints. Next, real-time project requirements are converted into query vectors, and the vector index is used to match a set of candidate project managers. Finally, the MOPSO
algorithm is used to search for feasible solutions, and non-dominated solutions are filtered using Pareto dominance relations, iteratively optimizing the optimal solution. The output is an interpretable result containing identifiers, matching scores, and
constraint satisfaction status and reasons. This invention eliminates cross-
system data conflicts through multi-feature comparison and source priority entity disambiguation mechanisms, ensuring the accuracy and timeliness of core information. Furthermore, relying on a multi-objective constraint set, optimization algorithms avoid irrelevant biases, ensuring that qualification review matching conforms to rules and regulatory fairness, thus comprehensively realizing the accuracy, fairness, and
standardization of qualification
information management.
