Method for extracting numbers in E-mail and device thereof

Abstract

The embodiment of the invention discloses a method for extracting numbers in an E-mail and a device thereof. The method comprises the steps that a single symbol in the E-mail is identified, and an identified result is obtained; classification determination is conducted on the identified result to obtain a determined result; the determined result is converted to obtain a pure digital number string. According to the method for extracting the numbers in the E-mail and the device thereof, numbers with separators and symbolic numbers in the subject or the content of the E-mail can be identified, the hybrid numbers are converted into the pure digital number string, the difficulty for extracting the numbers can be lowered, and the consumption of resources is lowered. Analysis of an anti-spam module and rule application in the E-mail are facilitated, so that whether the E-mail is a junk E-mail or not is quickly identified, and convenience is brought to a user.

Description

technical field [0001] The invention relates to the technical field of emails, in particular to a method and device for extracting numbers in emails. Background technique [0002] With the continuous development of mobile terminal technology, various mobile devices such as mobile phones, PDAs, tablets, and notebooks have become an indispensable part of people's work and life, and email is one of the most commonly used functions for people's office and communication. Among the various applications of Internet users, e-mail is a relatively common basic application. Users can send information to each other by sending e-mails, which is very convenient, but at the same time, the problem of spam e-mails arises.

The content of junk email includes promotional advertisements, adult advertisements, money-making information, or computer viruses, and even ...

AI Technical Summary

Problems solved by technology

[0005] The applicability of the method of directly searching for numbers that are all digits is relatively narrow, and it is only suitable for continuous number strings, and numbers with separators cannot be recognized; while using regular expressions for number recognition only recognizes and extracts strings that meet the rules, because It has powerful functions, which makes it difficult to write and test and verify, and consumes more resources

The numbers extracted by the above two methods are original character strings, which cannot be converted into ordinary pure digital strings, which is inconvenient for the analysis of the anti-spam module and the application of rules
