🏷️ Labels: Entity Resolution, Dedupe, Python, Jupyter, Data Cleaning
📂 Project: Dev
⭐ Priority: MEDIUM
Session Goal
The goal of this session was to implement a robust entity resolution process using the Dedupe.io library within Jupyter Notebooks, addressing common issues and optimizing the deduplication workflow.
Key Activities
- Reviewed robust entity resolution techniques focusing on clustering records using probabilistic and deterministic matching.
- Implemented Dedupe.io for probabilistic entity resolution in Python, utilizing active learning and fuzzy matching.
- Resolved command-line argument conflicts in Jupyter Notebooks related to the
optparse
library. - Adapted a Python script for deduplication using Dedupe in Jupyter, covering data loading to output saving.
- Corrected syntax for variable definitions in Dedupe 3.0, transitioning from dictionary to direct variable objects.
- Fixed a
ZeroDivisionError
in Dedupe by converting empty strings to None.
Achievements
- Successfully implemented a complete deduplication workflow in Jupyter using Dedupe.io.
- Resolved technical issues related to command-line arguments and variable definitions.
- Improved data cleaning processes by addressing common errors and optimizing the deduplication script.
Pending Tasks
- Further testing of the deduplication script on larger datasets to ensure scalability and efficiency.
