Natural Language Processing & Information Retrieval Consultations

Request This Service »

Biomedical information is often captured in clinical notes or literatures in natural human language (instead of using structured and standardized formats). The field of information retrieval is concerned with identifying documents within a large collection that are most relevant to a user’s search. We provide consultations for research utilizing natural language processing (NLP) or text mining methods to analyze and understand the information within natural language documents. 


Medical/Biological Literature-Based Extraction

  • Extraction of published evidences from medical or biological literatures (e.g., protein interactions, drug-disease treatment or preventative relations).

Clinical Information Extraction and Retrieval

  • Extraction of coded information from unstructured narratives (e.g., ejection fraction)
  • Human-computer information retrieval using interactive text visualization
