Spam Detection Using BERT

TL;DR

This paper presents a spam detection system using BERT that classifies emails and messages with high accuracy by understanding their context, trained on multiple datasets including Enron and SpamAssassin.

Contribution

The study introduces a BERT-based spam detector trained on diverse corpora, achieving high classification accuracy and demonstrating the effectiveness of transformer models in spam filtering.

Findings

Achieved over 98% accuracy on multiple datasets.

Demonstrated BERT's effectiveness in understanding message context.

Improved spam detection performance over traditional methods.

Abstract

Emails and SMSs are the most popular tools in today communications, and as the increase of emails and SMSs users are increase, the number of spams is also increases. Spam is any kind of unwanted, unsolicited digital communication that gets sent out in bulk, spam emails and SMSs are causing major resource wastage by unnecessarily flooding the network links. Although most spam mail originate with advertisers looking to push their products, some are much more malicious in their intent like phishing emails that aims to trick victims into giving up sensitive information like website logins or credit card information this type of cybercrime is known as phishing. To countermeasure spams, many researches and efforts are done to build spam detectors that are able to filter out messages and emails as spam or ham. In this research we build a spam detector using BERT pre-trained model that classifies emails and messages by understanding to their context, and we trained our spam detector model using multiple corpuses like SMS collection corpus, Enron corpus, SpamAssassin corpus, Ling-Spam corpus and SMS spam collection corpus, our spam detector performance was 98.62%, 97.83%, 99.13% and 99.28% respectively.
