About MIT Information Extraction Toolkit
MITIE is a library and tools for extracting information from text. It performs named entity extraction and binary relation detection, and includes tools for training custom extractors and relation detectors.
It provides pre-trained models for English, Spanish, and German, with a C++ core and bindings for languages including Python, R, Java, C, and MATLAB. Use requires downloading model files separately and compiling the library or tools.
Key features
- Named entity extraction from text
- Binary relation detection between entities
- Train custom extractors and relation detectors
- Pre-trained models for English, Spanish, and German
- Streaming command-line tool processes text line by line
- C++ core with bindings for Python, R, Java, and others
Best for: Developers building applications that need named entity extraction or relation detection in English, Spanish, or German text.
Good for
- Pre-trained models for English, Spanish, and German
- Core C++ library with bindings for Python, R, Java, C, MATLAB and others
