MULTI-TIERED ANTI-SPAMMING SYSTEMS AND METHODS

摘要

Embodiments are provided for reducing unwanted messages or spam within a real-time social networking service. According to certain aspects, a synchronous analysis module may operate in coordination with an asynchronous analysis module. Each of the synchronous analysis module and the asynchronous analysis module analyzes an incoming message from a user account to determine whether the incoming message has characteristics of spam, whereby the synchronous analysis is at a lower latency than the asynchronous analysis. The asynchronous analysis is afforded the ability to identify certain spam characteristics that the synchronous analysis may identify during its lower latency analysis.

1. A method of limiting undesired messages within a social networking service, the method comprising:
receiving, from a user of the social networking service, a message intended to be broadcast by the social networking service; synchronously analyzing the message, by a first computer processor, according to a set of characteristics of undesired messages, the set of characteristics stored in a database; asynchronously analyzing the message, by a second computer processor, including:
analyzing the message according to a machine learning algorithm for detecting undesired messages,identifying a characteristic of the message, andadding the characteristic to the set of characteristics in the database for the synchronous analyzing; based on at least one of the synchronous analyzing and the asynchronous analyzing, determining that the message is unwanted; and restricting propagation of the message in the social networking service based on determining that the message is unwanted.
