From d9c2a768430a60f10d226ecabd18dbd8d793dcb5 Mon Sep 17 00:00:00 2001 From: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Fri, 24 Oct 2025 06:11:17 +0000 Subject: [PATCH] Fix: Replace polyglot with NLTK alternatives to resolve HTTP 403 error - Removed polyglot dependency due to server unavailability (HTTP 403) - Replaced polyglot_stem() with nltk_alternative_stem() using NLTK stemmers - Updated to Python 3 print syntax for compatibility - Added comparison of Porter, Lancaster, and Snowball stemmers - Maintains same functionality without external server dependencies Resolves issue where polyglot.cs.stonybrook.edu returns 403 Forbidden when attempting to download morpheme analyzer resources.
