PDF Viewer Interface Transformation via Salient Term Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PDF viewer technologies are cumbersome and time-consuming due to the need to download entire documents for searching, which is inefficient and limits search capabilities to exact matches, especially in large PDFs used by technicians for vehicle service manuals.
Innovation Solution
A system that parses user requests to identify salient terms, generates user-selectable links for relevant pages within documents, and displays these links on a user interface, allowing direct navigation to specific pages within large PDFs, enabling fast browsing and flexible searching without the need to download the entire document.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the entire PDF is downloaded from the server, then the complete document is available for searching and viewing, but the download time and data usage are excessive
Solution Approach 1:
The system extracts only the necessary portions of the PDF document (specific pages or sections) and transforms them into web-compatible formats, rather than downloading the entire document. This extraction approach allows users to access only the relevant information needed for their search queries.
Solution Approach 2:
The PDF document is segmented into individual pages or sections, each transformed and stored separately as web pages. This segmentation enables the system to serve only the specific segments (pages) that contain the search results, rather than requiring the entire document to be downloaded.
2Speed
If the PDF is opened inside a PDF viewer, then download speed is improved by only downloading metadata and first few pages, but searching capabilities deteriorate to verbatim searches only
Solution Approach 1:
The system introduces an intermediary processing layer that transforms PDF content into web-compatible formats with embedded search indexes. This intermediary transformation enables full-text search capabilities to be implemented on the server side, allowing versatile searching without requiring the client to download the entire document.
3Loss of information
If the entire PDF is downloaded for searching, then comprehensive search results can be obtained, but the process is time-consuming and resource-intensive
Solution Approach 1:
The system performs preliminary actions by pre-transforming PDF documents into web-compatible formats and pre-indexing their content on the server before users need to search. This preliminary processing enables fast, comprehensive searches to be conducted on the server side without requiring users to download entire documents at the moment of searching.
4Measurement precision
If verbatim search is used in existing PDF viewers, then exact matches can be found, but fuzzy searching and flexible search capabilities are limited
Solution Approach 1:
The system changes the search parameter implementation by performing all search operations on the server side with access to pre-indexed content. This allows the search system to implement various search algorithms including fuzzy matching, partial matches, and flexible query processing, rather than being constrained to simple client-side verbatim searches.
Data Source
AI summary
A system includes a memory configured to store a database including a plurality of documents and instructions. The system includes at least one processor configured to execute the instructions. The instructions include, in response to receiving a request signal from a user device, parsing the request signal to identify salient terms, identifying a set of documents of the plurality of documents based on the identified salient terms, and displaying the set of documents on a user interface of the user device.
