Solution Overview

Problem

Existing Named Entity Recognition (NER) processes require multiple passes through a machine learning model to determine multiple characteristics of text, consuming significant time and computational resources, making them inefficient for large datasets.

Innovation Solution

A method that combines characteristics into a single input for a machine learning model, using techniques like Bidirectional Encoder Representations from Transformers (BERT) to generate interaction embeddings for efficient extraction of multiple characteristics in a single pass, reducing resource consumption and training time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple passes through the machine learning model are used to determine multiple characteristics, then the accuracy and completeness of characteristic extraction is improved, but the time consumption and computational resources increase significantly

Engineering Contradiction:
Improvecharacteristic extraction accuracyVSAvoidanalysis time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges multiple characteristic extraction tasks into a single machine learning model inference pass. Instead of running separate passes for each characteristic (e.g., brand, category, color, size), the system combines all characteristics into one unified model that processes the text once and outputs all characteristic labels simultaneously, thereby reducing time consumption while maintaining extraction accuracy

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The machine learning model is designed with multi-functionality to perform multiple NER tasks concurrently. The model is trained to recognize multiple characteristics (brand name, category, color, size) within a single pass, making the system universally applicable to various product attribute extraction tasks without requiring separate specialized models for each characteristic

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A machine learning model analyzes text describing an item to determine portions of the text that correspond to multiple characteristics of the item. A first set of embeddings that represent the text describing the item is determined. A second set of embeddings that represent text indicating the characteristics is determined. The second set of embeddings includes a token for each characteristic that is used to indicate tokens that are associated with a particular characteristic. The first set of embeddings and portions of the second set of embeddings for a particular characteristic are used to determine a set of interaction embeddings for each characteristic by determining an element-wise product. These interaction embeddings are analyzed to determine label predictions indicating text that is associated with each characteristic. Text for multiple characteristics may therefore be identified using a single pass rather than multiple passes.
