About

MENTHOS-Spam is a binary text classification dataset for spam/phishing detection. It is created by combining email and SMS spam sources and then producing train/validation/test splits.

Source Data

Original sources:

• Phishing Email Dataset (Kaggle): https://www.kaggle.com/datasets/naserabdullahalam/phishing-email-dataset
• SMS Spam Collection (Kaggle mirror of UCI dataset): https://www.kaggle.com/datasets/uciml/sms-spam-collection-dataset

Processing and Balancing

• Unified schema: text, label
• Label mapping for SMS source: ham -> 0, spam -> 1
• Split: 70% train, 15% validation, 15% test
• Balancing: each split is balanced by downsampling to the minority class count

Splits and Class Distribution

The prepared train, validation, and test splits are included with the dataset release.

split	rows	label 0	label 1
train	60982	30491	30491
validation	13166	6583	6583
test	13128	6564	6564

O datasetu

MENTHOS-Spam je binarni dataset za detekcijo spam/phishing besedil. Nastane z združitvijo e-poštnega in SMS vira ter z gradnjo train/validation/test delitev.

Izvorni podatki

Izvor:

• Phishing Email Dataset (Kaggle): https://www.kaggle.com/datasets/naserabdullahalam/phishing-email-dataset
• SMS Spam Collection (Kaggle ogledalo UCI): https://www.kaggle.com/datasets/uciml/sms-spam-collection-dataset

Obdelava in uravnoteženje

• Enotna shema: text, label
• Preslikava oznak za SMS vir: ham -> 0, spam -> 1
• Delitev: 70% train, 15% validation, 15% test
• Uravnoteženje: vsak split je uravnotežen z downsamplingom na manjšinski razred

Delitve in porazdelitev razredov

Pripravljene train, validation in test delitve so vključene v izdajo nabora podatkov.
