What is Caterpillar? ==================== .. image:: https://img.shields.io/travis/Kapiche/caterpillar.svg?style=flat-square :target: https://travis-ci.org/Kapiche/caterpillar .. image:: https://img.shields.io/coveralls/Kapiche/caterpillar.svg?style=flat-square :target: https://coveralls.io/r/Kapiche/caterpillar Caterpillar is a pure Python text indexing and analytics library. It is aimed at supporting advanced text and other semi-structured analytics applications that bridge Natural Language Processing (NLP), Information Retrieval and Topic Modelling. Some features include: * pluggable key/value object store for storage (currently only implementation is SQLite) * transaction layer for reading/writing (along with associated locking semantics) * supports searching indexes with some built in scoring algorithm implementations (including TF/IDF) * stores additional data structures for analytics above and beyond traditional information retrieval data structures * has a plugin architecture for quickly accessing the data structures and performing custom analytics * has 100% test coverage Quick Example ============= Quick example of using caterpillar below:: import os import tempfile from caterpillar.processing.index import IndexWriter, IndexConfig from caterpillar.processing.schema import TEXT, Schema, NUMERIC from caterpillar.storage.sqlite import SqliteStorage index_dir = os.path.join(tempfile.mkdtemp(), "examples") with open('caterpillar/test_resources/moby.txt', 'r') as f: data = f.read() with IndexWriter(index_dir, IndexConfig(SqliteStorage, Schema(text=TEXT, some_number=NUMERIC))) as writer: writer.add_document(text=data, some_number=1) Installation ============ .. code:: pip install caterpillar Documentation ============= The documentation can be found `here <http://caterpillar.readthedocs.org/en/latest/>`_. Roadmap ======= Caterpillar is currently in a volatile state, and the next releases are likely to undergo substantial changes in the API. In particular we plan to: * Revamp schema and field design, in order to: - better merge the core text indexing with extraction of structured information. For example, integrating and indexing documents by both their textual context and entities identified by a named entity extraction approach - integrate the serialisation of schemas within the transactional lifetimes of IndexWriter objects * Improve locking to allow better support for concurrency when indexing large collections * Support more languages, in particular to allow multilingual indexes with appropriate markup and representation of different languages * Remove the NLTK dependency (great library, but only used for tokenisation) * Better API for completely customising what and how data is extracted from documents Python Version ============== Caterpillar now targets Python 3 only. It is intended to support the two most recent releases of Python for new features. Currently this means we aim to support Python 3.5 and 3.6 only. BDFLs ===== * `Kris Rogers <https://github.com/krisrogers/>`_ * `Ryan Stuart <https://github.com/rstuart85/>`_ * `Sam Hames <https://github.com/SamHames/>`_ Contributors ============ Anyone who is willing! In other words none yet, but we are more then accepting of contributions. Contributing ============ No code will be merged unless it has 100% test coverage and passes the flake8 linting. We code with a line length of 120 characters (see tox.ini [pep8] section) and we use `py.test <http://pytest.org/>`_ for testing. Tests are in a *test*sub-folder in each package. Tox is configured to run the test suite, reporting unit test passes, coverage and linting automatically. .. code:: # Run the whole test suite: tox # Run just the linting checks by specifying a specific test environment: tox -e flake8 # Pass some arguments to py.test through the tox runner (in this case run only a specific set of tests) tox -e py35 -- -k test_index Copyright and License ===================== Caterpillar is copyright © 2013 - 2015 Kapiche Limited.
