Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Unstructured electronic document collections lack a common structure, making it difficult to extract and present information coherently, as documents can have diverse formats and lack mechanisms for ensuring consistency, whereas structured collections are restrictive and difficult to change.

Innovation Solution

A method that retrieves and displays information from unstructured collections by identifying new values and attributes, and integrating them into a structured presentation, allowing for a systematic and coherent visual arrangement, even across diverse sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If unstructured electronic document collection is used, then document format diversity and flexibility are improved, but information extraction coherence and structure consistency deteriorate

Engineering Contradiction:

Improvedocument format diversityVSAvoidinformation extraction coherence

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent introduces a structured presentation as an intermediary layer between unstructured documents and the user interface. This mediator extracts information from diverse unstructured formats and re-presents it in a consistent structured format, enabling both document format diversity and information coherence simultaneously

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system segments the information extraction process into independent attribute extraction units. Each attribute is extracted separately from unstructured documents and then assembled into a structured presentation, allowing flexible handling of diverse document formats while maintaining structured output consistency

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If structured electronic document collection is used, then information extraction coherence is improved, but adaptability to format changes and flexibility deteriorate

Engineering Contradiction:

Improveinformation extraction coherenceVSAvoidformat change flexibility

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic attribute detection where the system automatically identifies and adapts to different attribute formats in unstructured documents. The structured presentation framework dynamically adjusts to accommodate varying document formats while maintaining consistent information extraction and presentation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of document structure from fixed to flexible by allowing unstructured documents to have varying formats while the extraction process adapts to extract consistent attributes. The structured presentation maintains parameter consistency in the output regardless of input document variability

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If pre-existing format constraints are imposed, then structured presentation consistency is improved, but ability to accommodate diverse document formats deteriorates

Engineering Contradiction:

Improvestructured presentation consistencyVSAvoiddiverse document format accommodation

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The structured presentation serves as a mediator that receives diverse unstructured document formats and transforms them into a consistent structured representation, maintaining both format diversity in input and structural consistency in output

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a universal structured presentation framework that can accommodate multiple document formats and attribute types. This multi-functional system handles various unstructured formats while presenting unified structured output, eliminating the need for format-specific processing rules

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Methods, systems, and apparatus, including computer programs stored on computer storage media, for populating a structured presentation with new values. One aspect can be embodied in machine-implemented methods that include the actions of obtaining a plurality of instances and a plurality of attributes; for each instance: identifying one or more documents from an unstructured document collection that are relevant to the instance, where each of the one or more documents include at least a value for an attribute in the plurality of attributes; and establishing a subset of the one or more values as characterizing the instance; and adding each instance, the respective attributes, and the respective subset of values to a structured data collection.
