MeTA is a modern C++ data sciences toolkit. It’s a suite of natural language processing, classification, information retrieval, data mining, and other applications of text processing.
MeTA’s emphasis focuses on the tight integration of search capabilities (indeed, text access capabilities in general) with text analysis functions, enabling it to provide full support for building a powerful text analysis application.
Another design philosophy of MeTA is to facilitate education and research experiments with various algorithms. In this direction, it is similar to Indri/Lemur in its emphasis on modularity and extensibility achieved through object-oriented design. It enables flexible configuration of a selected subset of modules so as to make it easy for designing course assignments or experimenting with a few selected algorithms as needed in focused research projects.
Features include:
- Text tokenization, including deep semantic features like parse trees.
- Inverted and forward indexes with compression and various caching strategies.
- A collection of ranking functions for searching the indexes.
- Topic models.
- Classification algorithms.
- Graph algorithms.
- Language models.
- CRF implementation (POS-tagging, shallow parsing).
- Wrappers for liblinear and libsvm (including libsvm dataset parsers).
- UTF8 support for analysis on various languages.
- Multithreaded algorithms.
