Document Telephone Number Extraction for Direct Voice Call Initiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current web search technologies do not easily facilitate the retrieval of telephone number information associated with search results, limiting users' ability to initiate calls directly from search results.
Innovation Solution
A method that retrieves and parses documents to extract embedded telephone numbers, allowing users to initiate voice calls to these numbers, either through direct document retrieval or search query results, using client-server architectures and network connections for VOIP or traditional calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If search engines return hyperlinks to web pages based on search queries, then users can access relevant information, but users cannot easily initiate telephone calls from search results
Solution Approach 1:
The patent embeds multiple functionality within search result documents by incorporating telephone number tags (e.g., <tel:>) into HTML code. This allows search results to serve both traditional information delivery and direct telephone call initiation, making the search engine system multi-functional without requiring separate systems.
Solution Approach 2:
The patent introduces an intermediary component (telephone number extraction system) that bridges web search results and telephone network access. The system extracts telephone numbers from document code, validates them, and routes calls through appropriate protocols (VOIP or traditional telephony), acting as a mediator between these previously disconnected systems.
2Ease of operation
If telephone numbers are embedded in document code, then call initiation is facilitated, but document complexity increases
Solution Approach 1:
The patent applies local quality by embedding telephone number information only in specific locations within document code where it is needed (e.g., contact information sections), rather than throughout the entire document. This targeted approach provides call functionality where required without unnecessarily complicating the overall document structure.
Solution Approach 2:
The patent uses standardized telephone number tag formats (e.g., <tel:+1234567890>) that can be copied and reused across multiple documents. This standardization reduces complexity by providing a template that can be replicated rather than requiring custom implementation for each document.
3Reliability
If the system analyzes multiple documents to find telephone numbers, then call accuracy improves, but processing time increases
Solution Approach 1:
The patent performs preliminary action by pre-processing and indexing telephone number information during document crawling and storage. When a user searches, the system can quickly retrieve pre-identified telephone numbers associated with search results, rather than analyzing entire documents in real-time. This reduces processing time while maintaining accuracy.
Solution Approach 2:
The patent extracts telephone number information from documents during indexing, separating this data from the main document content. This extracted information is stored in a dedicated format that enables rapid retrieval and association with search results, improving both speed and accuracy of telephone number identification during user queries.
Data Source
AI summary
A system receives an indication of a document selected from a corpus of documents and determines a telephone number associated with the selected document. The system facilitates a voice call to the telephone number.
