Neural Network Candidate Matching System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HR systems face challenges in accurately matching candidates with job openings due to poor recall and precision in keyword-based searches, lack of context understanding regarding skill depth, learnability, and relevancy of industry experience, leading to false positives and false negatives.
Innovation Solution
A system that creates enriched talent profiles and calibrated job profiles using deep neural networks, incorporating resume data, public data analysis, and related-entity insights to predict candidate suitability, including personality and talent assessments, and provides a deeper understanding of candidate and job requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If keyword-based matching is used to identify candidates, then the system is simple and fast to operate, but recall and precision are poor leading to false positives and false negatives
Solution Approach 1:
The patent replaces the mechanical keyword-matching system with a deep neural network-based semantic analysis system. The DNN model processes enriched talent profiles and calibrated job profiles to understand candidate suitability beyond keyword presence, substituting simple string matching with intelligent semantic comprehension to improve matching precision while maintaining operational efficiency
Solution Approach 2:
The system transforms the matching parameters from simple keyword presence/absence to complex semantic features including skill depth, learnability, industry experience relevancy, and personality traits. By changing the parameter space from discrete keywords to continuous semantic vectors, the system achieves better recall and precision in candidate identification
2Measurement precision
If keyword search is made specific to improve precision, then false positives decrease, but recall decreases causing false negatives
Solution Approach 1:
The patent adds multiple dimensions to the matching process beyond keyword presence, including skill depth, learnability, industry experience relevancy, personality traits, and predicted next role. By expanding from one-dimensional keyword matching to multi-dimensional semantic analysis, the system identifies qualified candidates who may not have exact keyword matches but possess relevant capabilities and potential
3Measurement precision
If enriched talent profiles and deep neural networks are used to improve matching accuracy, then candidate prediction precision improves, but system complexity increases
Solution Approach 1:
The system performs preliminary enrichment of talent profiles and job profiles before the actual matching process. By pre-processing and enriching the input data with relevant features, skills, experiences, and traits, the system simplifies the subsequent matching operation while maintaining high accuracy. The calibration of job profiles using historical hiring data also prepares the system in advance for more accurate predictions
4Reliability
If context understanding is added to understand skill depth and industry experience, then matching quality improves, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary enrichment of talent profiles by extracting and organizing contextual information such as skill depth, industry experience, and personality traits before the matching process. This pre-processing step consolidates contextual data so that during actual matching, the deep neural network can efficiently process pre-packaged semantic features rather than analyzing raw data in real-time, reducing processing time while maintaining reliability

AI summary
A method and system for predicting a match between a candidate and a job position for an organization include generating an enriched talent profile associated with the candidate, the enriched talent profile comprising first characteristic values and second characteristic values, wherein the first characteristic values relate to characteristics verifiably possessed by the candidate, and second characteristic values are predicted values by executing a first neural network module, generating a calibrated job profile for the job position, the calibrated job profile comprising job requirements for the job position, and executing a second neural network module using the enriched talent profile and the calibrated job profile as inputs to calculate one or more hire-related prediction values for the candidate.
