Solution Overview

Problem

Conventional property appraisal methods struggle to accurately identify and account for qualitative variables in comparable properties, leading to subjective and potentially inaccurate valuations due to inconsistent terminology and reliance on manual review of agent notes, which can result in financial discrepancies and market instability.

Innovation Solution

An appraisal engine that utilizes natural language processing and machine learning to parse property specifications, including text and images, to identify comparable properties with similar qualitative variables, providing a more objective and reliable appraisal process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual review of agent notes is used to identify qualitative variables, then flexibility in handling diverse property features is maintained, but consistency and objectivity of appraisal deteriorates due to subjective judgment and inconsistent terminology

Engineering Contradiction:

Improveobjectivity of appraisalVSAvoidcomplexity of qualitative variable identification

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical review process with an automated machine learning system that uses natural language processing to identify qualitative variables from property descriptions, eliminating subjective human judgment while maintaining the ability to handle diverse property features through trained models

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service by automatically extracting and identifying qualitative variables from property listings without requiring manual intervention, allowing the appraisal process to self-regulate consistency through standardized algorithmic evaluation rather than human discretion

Inventive Principle:

Principle #25Self-service

2Measurement precision

If conventional appraisal methods are used, then ease of operation is maintained through manual processes, but measurement precision of qualitative variables deteriorates due to inability to systematically identify and compare similar features

Engineering Contradiction:

Improveprecision of qualitative variable identificationVSAvoidease of property evaluation

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent substitutes manual mechanical evaluation with automated machine learning algorithms that precisely identify and measure qualitative variables through natural language processing, achieving high measurement precision while the system handles the operational complexity automatically

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system transforms qualitative property descriptions into standardized measurable parameters through machine learning models, converting subjective attributes into quantifiable data points that can be precisely measured and compared across properties

Inventive Principle:

Principle #35Parameter changes

3Measurement precision

If comprehensive inspection of all property features is performed, then accuracy of appraisal value is improved, but time required for appraisal process increases due to manual review requirements

Engineering Contradiction:

Improveaccuracy of appraisal valueVSAvoidtime for property evaluation

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces time-consuming manual inspection with automated machine learning systems that rapidly analyze property features through natural language processing and image recognition, achieving comprehensive accuracy in a fraction of the time required for manual review

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables continuous automated analysis of property features without interruption, maintaining constant evaluation readiness and eliminating the intermittent nature of manual inspection, thereby reducing total time while maintaining comprehensive accuracy through continuous data processing

Inventive Principle:

Principle #20Continuity of useful action

AI summary

Systems and methods herein provide an appraisal engine and its related functions. In an example, an appraisal engine may identify a target property for appraisal and based on the target property determine comparable properties. The appraisal engine may also determine one or more qualitative variables associated with the target property and determine which of the comparable properties include the qualitative variables. In some cases, the appraisal engine may generate visual representations of the qualitative variables for a respective comparable property. The appraisal engine may generate a listing of a subset of comparable properties that include the qualitative variables and generate an appraisal value for the target property based on the subset of comparable properties including the qualitative variables.
