The ideas are grouped by what the feature describes , why it matters, and how to compute it in a reproducible way (Python‑friendly pseudo‑code is included). 1. Text‑Based Features (what the subject says ) | # | Feature | Why it matters | Simple extraction (Python) | |---|---------|----------------|-----------------------------| | 1 | Token Count | Very short or very long subjects are atypical for legitimate business mail. | len(subject.split()) | | 2 | Character Count | Spam often packs many characters to hide keywords. | len(subject) | | 3 | Average Token Length | Long words → possible obfuscation. | np.mean([len(t) for t in subject.split()]) | | 4 | Upper‑case Ratio | Excessive caps = “shouting”, common in phishing. | sum(1 for c in subject if c.isupper()) / len(subject) | | 5 | Digit Ratio | High proportion of numbers (e.g., “840‑2024”) is a red flag. | sum(c.isdigit() for c in subject) / len(subject) | | 6 | Presence of Action Verbs (download, click, open, update…) | Direct calls‑to‑action are hallmark of malicious prompts. | any(v in subject.lower() for v in "download","click","open","update","verify") | | 7 | Suspicious Keywords (work, urgent, invoice, account, password…) | Common lure words. | any(k in subject.lower() for k in suspicious_word_list) | | 8 | Stop‑Word Ratio | Spam often reduces natural language flow → low stop‑word density. | stop_words = set(nltk.corpus.stopwords.words('english')) stop_ratio = sum(1 for t in tokens if t.lower() in stop_words) / len(tokens) | | 9 | N‑gram TF‑IDF Scores (bi‑grams, tri‑grams) | Captures patterns like “download work”, “840‑2024”. | Use sklearn.feature_extraction.text.TfidfVectorizer(ngram_range=(2,3)) on a corpus of subjects. | |10| Language Detection | “Bengla” hints at a language mismatch (English subject + foreign term). | langdetect.detect(subject) – flag if not the primary language of the organization. | |11| Spell‑Check Ratio | Misspellings (“Bengla” vs “Bangla”) are common in malicious mail. | spellchecker.unknown(tokens) → proportion. | |12| Entropy of Characters | High entropy can indicate random strings or encoded data. | entropy = -sum(p*np.log2(p) for p in np.bincount(list(subject.encode()))/len(subject)) | 2. URL‑Centric Features (what the subject exposes ) Even though the URL lives after the dash, the presence and shape of a domain in the subject is a strong signal.
