Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Businesses face challenges in searching non-text-based materials like image text documents and audio files, as current search engines can only utilize metadata, leading to limited and inaccurate search results due to the lack of searchable content within these files.

Innovation Solution

A system and method that processes audio text files by linguistically analyzing them within multiple lexicons, creating reflection files, and storing these in a repository for improved searchability, allowing for the conversion of audio files into text documents that can be searched using standard search engines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If audio files are stored and received by businesses, then the quantity of stored material increases, but the ability to search the content therein is lost

Engineering Contradiction:

Improvequantity of stored materialVSAvoidability to search content

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent introduces an intermediary text file that bridges audio files and search engines. The text file contains transcribed or indexed content from the audio file, allowing search engines to query the text while the original audio remains intact. This intermediary layer enables searching without requiring direct audio-to-text conversion for every operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a textual copy or representation of the audio content that can be independently searched. This copy may be a full transcription, keyword-indexed text, or metadata-rich text file that mirrors the audio content's essential information, enabling search operations on the copy while preserving the original audio file.

Inventive Principle:

Principle #26Copying

2Speed

If only metadata is searched in image text documents, then search speed is maintained, but search accuracy and completeness deteriorate

Engineering Contradiction:

Improvesearch speedVSAvoidsearch accuracy

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The patent segments the search process into two distinct phases: a fast metadata filtering phase that quickly narrows down results, and a more detailed text content analysis phase that provides accurate matching. This segmentation allows the system to maintain speed through efficient metadata indexing while achieving accuracy through subsequent detailed text searching of the segmented results.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary indexing and text extraction during document ingestion, preparing the full text content in advance for future searches. This preliminary action creates pre-processed text representations that can be quickly queried, eliminating the need for slow on-the-fly text extraction during search operations.

Inventive Principle:

Principle #10Preliminary action

AI summary

A system and method for processing audio text files includes a content repository storing audio text files. A text transformer linguistically analyzes the audio text files within a content of multiple lexicons to form edited text results and creates a reflection repository having reflection files therein corresponding to the audio text files from the edited text results. A search engine searches the reflection files and a user device displays a first reflection file from the reflection files or a first audio text file from the audio files in response to searching.
