Inessa Cho

Independent researcher & prospective graduate student focused on
Information Retrieval (IR), NLP, and robust retrieval systems under distribution shift.

Interested in how language, meaning, and retrieval reliability evolve across noisy online environments.


Research Interests

  • Information Retrieval (IR)
  • Robust NLP under distribution shift
  • Retrieval systems in noisy/open-world environments
  • Semantic anomaly & representation analysis
  • OOD detection for embeddings and LLM systems
  • Language & narrative shift across online communities
  • OSINT-oriented text mining workflows

Current Focus

  • Retrieval pipelines (BM25, dense retrieval, reranking)
  • Embedding-space anomaly detection
  • Semantic drift & temporal language shift
  • Retrieval failure analysis under noisy data
  • AI-assisted paper reproduction workflows
  • Lightweight NLP/IR experimentation systems
