Collocation analysis

Collocation analysis shows which words frequently co-occur with your search term.

How to access

1. Click on Collocation to switch to Collocation mode
2. Enter a search word

3. Click on the Colloc 2 or Colloc 3 tab

4. Colloc 2: Shows 2-word collocations (bigrams containing your search term)

5. Colloc 3: Shows 3-word collocations (trigrams containing your search term)

Sort options

You can sort collocation results by different statistical measures:

Measure	Description
MI (Mutual Information)	Measures how strongly two words are associated. Higher values indicate stronger, often more specific collocations.
t-score	Balances association strength with frequency. Tends to highlight frequent, reliable collocations.
Freq (Frequency)	Simple co-occurrence frequency count.
DP (Delta P)	Directional association measure. Shows how much more likely word B is given word A, compared to its overall probability.

Lemma-based grouping

Collocation results are grouped by lemma (base form). This means that all inflected forms of a word are combined into a single entry. For example, searching for "make" will show:

• make + mistake — combining "make a mistake", "makes mistakes", "made a mistake", etc.
• make + decision — combining all inflected forms

The frequency shown for each pair is the sum over all these forms. Hover over a lemma to see all the surface forms that were aggregated. Click on a row to search for all instances using lemma search syntax.

Tips

• MI scores tend to highlight rare but strongly associated pairs
• t-scores are better for finding common, reliable collocations useful for learners
• Try different sort options to get different perspectives on word combinations
• Click on any collocation to search for its instances in the transcript corpus
• Hover over a lemma cell to see all surface form variants
