Controlling Context Granularity and Encoding Local Context for Title Boosted Web Search in ColBERT

Codes for research submitted to Late Interaction Workshop @ ECIR2026. We loaded the stanford-colbert codes (https://github.com/stanford-futuredata/ColBERT) and added scripts used in our analyses and experiments.

• Analysis
  • stanford-colbert/ColBERT/context_granularity_analysis.ipynb
• Experiment
  • stanford-colbert/ColBERT/experiment_querytitle_tokenmatch.ipynb
• Case Study (Index Construction and Search)
  • We modified the stanford-colbert/ColBERT/colbert/modeling/checkpoint.py by adding the docFromText_titlesep method to the ColBERT Checkpoint class
