Solution Overview

Problem

The hiring process is inefficient due to the manual and resource-intensive identification of disparities between job requirements and candidate skills, particularly with unstructured interview notes that lack standardization, leading to subjective and inaccurate candidate evaluations.

Innovation Solution

A computer-implemented method using text analysis and machine-learning models to extract and rank candidate skills from CVs and job descriptions, and to analyze interview notes for impression scores, enabling objective and dynamic assessment of candidate suitability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual screening and evaluation methods are used, then hiring decisions can be made with human judgment, but the process becomes time-consuming and resource-intensive

Engineering Contradiction:
Improvehiring decision accuracyVSAvoidscreening process duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical screening processes with an automated computer-implemented system that uses text analysis engines to process CVs, job descriptions, and interview notes. The system automatically extracts skills, computes matching scores, and generates hiring recommendations, eliminating the need for manual review of each document while maintaining evaluation accuracy through algorithmic processing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service screening where the text analysis engine autonomously performs the entire evaluation process without human intervention. It automatically extracts information from unstructured text, computes skill disparities, determines matching scores, and generates recommendations, allowing the system to serve itself in the screening process rather than requiring continuous human oversight for each evaluation step.

Inventive Principle:
Principle #25Self-service

2Loss of information

If unstructured interview notes are analyzed manually, then interviewer impressions can be captured, but objective data analysis becomes infeasible and decisions become subjective

Engineering Contradiction:
Improveinterviewer impression captureVSAvoidevaluation objectivity
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The patent replaces manual subjective analysis of unstructured interview notes with an automated text analysis engine that objectively processes the text. The system extracts structured data from unstructured notes, identifies skills and impressions, and computes quantitative matching scores, transforming subjective human judgment into objective measurable data while preserving all interviewer impression information.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system transforms the qualitative parameters of unstructured interview notes into quantitative parameters through automated analysis. By converting text-based impressions into structured data with measurable attributes (skill matches, impression scores, disparity metrics), the system enables precise objective measurement while maintaining the full richness of the original unstructured information through the feedback-based model.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If automated text analysis is applied to unstructured data, then processing speed increases, but the complexity of the analysis system increases

Engineering Contradiction:
Improvedata processing speedVSAvoidtext analysis system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the complex text analysis task into distinct manageable modules: CV processing module, job description analysis module, interview notes analysis module, skill extraction module, and recommendation generation module. Each module handles a specific aspect of the analysis independently, allowing the system to process unstructured data efficiently while keeping each individual component relatively simple and maintainable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces a feedback-based model as an intermediary layer that simplifies the relationship between raw unstructured text and final hiring recommendations. This intermediary model processes the output from various text analysis components, integrates the information, and generates unified recommendations, thereby managing system complexity through a mediating processing layer that coordinates multiple analysis functions.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

One example method includes identifying, using a text analysis engine and in a digitized text representing notes of an interviewer regarding an interviewee, a landmark indicating an impression of the interviewer toward the interviewee. An impression score can then be computed, based on the landmark and context of the landmark in the digitized text. A plurality of impression scores including the impression score can then be combined to generate an aggregate impression score indicating an overall impression of the interviewer toward the interviewee. Data representing impression relating to the interviewee, where the data can include the aggregation impression score, can then be provided for display on a client device.
