Detecting Stale Facts in Documents via Pre-Processed Factoids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for updating factual information in computer-readable documents are cumbersome and inefficient, requiring manual searches across multiple storage locations and often resulting in redundant efforts and errors, especially when users lack knowledge of database query languages.
Innovation Solution
A computing system that uses natural language processing and deep learning to automatically identify outdated facts in documents, generate factoids with updated information, and prompt users to replace outdated values, eliminating the need for manual database queries and improving real-time updating capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual searching is performed across multiple storage locations to find current fact values, then the user can obtain updated information, but the process becomes computationally burdensome and time-consuming
Solution Approach 1:
The system performs preliminary actions by pre-processing documents to extract factoids and storing them in a data store with associated topics and classifications before they are needed. When a document is opened or facts need updating, the system queries this pre-processed data store rather than searching all documents again, significantly reducing the time required to find current fact values.
Solution Approach 2:
The system introduces an intermediary layer (the data store containing pre-extracted factoids) between the user's information need and the source documents. This intermediary structure allows efficient querying by topic and classification without requiring users to manually search through multiple storage locations, resolving the contradiction between obtaining updated information and minimizing search time.
2Loss of information
If users manually review documents to identify outdated facts, then they can update information, but the process is cumbersome and error-prone
Solution Approach 1:
The system performs self-service by automatically identifying outdated facts in documents, querying the data store for current fact values, and presenting update recommendations to users. This eliminates the need for users to manually review documents to identify outdated information, making the process easier and less error-prone while still achieving the goal of updating lost information.
Solution Approach 2:
The system implements feedback by comparing fact values in documents against the pre-processed data store, automatically identifying when facts are outdated, and presenting targeted update recommendations to users. This feedback mechanism guides users through the updating process, reducing cognitive load and minimizing errors compared to manual review.
3Loss of information
If comprehensive searches are performed to find all relevant fact values, then completeness is improved, but the number of search result documents increases, making it harder to find the right information
Solution Approach 1:
The system segments the large corpus of documents into discrete, pre-processed factoids stored in a structured data store. Each factoid is associated with topics and classifications, allowing the system to segment the search space by querying only relevant factoids rather than searching all documents. This segmentation maintains completeness of information retrieval while eliminating the overwhelming volume of search results.
Solution Approach 2:
The system applies local quality by organizing factoids with specific topic and classification metadata that reflects their content and relevance. When querying for current fact values, the system uses these localized quality attributes to filter and retrieve only the most relevant factoids, making it easy to identify the correct information without being overwhelmed by unrelated search results.
4Measurement precision
If database query languages are used to search for current fact values, then accurate results can be obtained, but users must possess specialized knowledge that many do not have
Solution Approach 1:
The system replaces complex, specialized database query languages with a simple, user-friendly interface that presents factual statements and update recommendations in plain language. Users interact with the system through natural language or simple UI elements rather than requiring knowledge of SQL or other database query languages, dramatically improving accessibility while maintaining accurate retrieval of current fact values through the underlying structured data store.
Data Source
AI summary
A computing system obtains a document that includes text. The computing system identifies a fact referenced in the text of the document, where the fact includes a fact name and a fact value. The computing system determines a topic of the document based upon the text of the document. The computing system identifies a factoid stored in a data store based upon the topic and the fact name, where the factoid includes the fact name and a second fact value, and further where the factoid has been generated based upon second text of a second document. While the document is being displayed to a user, the computing system causes a message to be displayed to the user, where the message prompts the user to accept or reject replacement of the fact value in the document with the second fact value.
