N-gram (Bigram / Trigram) Analyzer

מחלץ את הביגרמים, טריגרמים, 4-גרמים ו-5-גרמים הנפוצים ביותר בכל טקסט. מסנן לפי תדירות מינימלית.

מתי להשתמש

Use the n-gram analyzer to find common phrases in writing, transcripts, or scraped content. Especially useful for SEO topical analysis, content gap analysis, and discovering author voice patterns.

השוואה

The n-gram analyzer is more general than Keyword Density (no SEO framing). It's the natural next step after Word Frequency if you suspect important phrases lie above the single-word level.

איך זה עובד

An n-gram is a contiguous sequence of n words from a text. Bigrams are 2-word sequences ("machine learning"); trigrams are 3-word ("artificial neural network").

The analyzer counts every n-gram, filters by minimum frequency, and optionally drops phrases composed entirely of stopwords.

Lowercase normalization treats "The Cat" and "the cat" as the same n-gram — usually what you want for analysis.

שאלות נפוצות

What's the difference between this and keyword density?

Keyword density adds percentages and over-optimization warnings for SEO. The n-gram analyzer is a general phrase-frequency tool without the SEO framing.

Why drop pure-stopword phrases?

Without filtering, the top n-grams are always "of the", "in the", "to the" — uninformative. The filter drops phrases composed entirely of stopwords.

When should I use n=4 or n=5?

For finding repeated long phrases — quotes, slogans, boilerplate. Most useful n is 2 or 3.

דוגמה מעשית

קלט

500-word product description.

פלט

Top bigrams: "machine learning" (8), "neural network" (5), "training data" (4).

N-grams reveal the actual phrases that dominate a text, including phrases the writer didn't consciously target. Useful for SEO topic discovery and content audit.

מלכודות נפוצות

  • Without the stopword purge filter, top n-grams will be filled with "of the", "in the", "and the".
  • Short texts (<200 words) rarely produce stable n-grams.
  • Phrasal verbs and idioms span 2–3 words — n=2 and n=3 catch different things.
  • Hapax phrases (appearing once) flood the results — set min frequency ≥ 2.
