Programming Languages
PyElly is a rule-based natural language processing tool that has existed
for over forty years in various incarnations. It is now free for download
from the Web as open source software. It is written entirely in
version 2.7 of Python and employs SQLite for data management.
PyElly is intended mainly for educational use. It allows a student to
engage natural language at a fine level of detail and to learn the issues
involved in processing text data. It can be of interest to others, though,
because of its extensive support for handling the messy aspects of
language not central to most text data problems or to their solutions.
The basic paradigm of PyElly is to rewrite natural language input into
some other text output, which might be SQL, XML, or some other form. This
falls short of full understanding, but can be quite helpful as a general
kind of preprocessing for data mining or for more precise indexing.
PyElly tools include flexible tokenization, syntax-driven parsing, English
inflectional and morphological stemming, macro substitutions, basic
and extended entity extraction, ambiguity handling, sentence recognition,
support for large external dictionaries, and a general procedural
framework for translating text from UTF-8 to UTF-8.

The latest versions have been completely rewritten in object-oriented
Python. It completed beta testing in 2014 and can be found on
GitHub at https://gith$ub.com/prohippo/pyelly.git . Development and
refinement of PyElly software is ongoing.
To learn how to use PyElly, see the PyEllyManual.pdf file in the same
directory as this README.txt file. The manual has about 170 pages
of information, including an overview of basic linguistics. Documentation
of individual Python source files can be generated as needed by running
the Python pydoc utility on the source files.
At present, PyElly consists of 67 Python modules comprising about eleven
thousand lines of source code. The PyElly package also includes various
language definition files with rules implementing a broad range of
nontrivial example applications; these include
* indexing - remove stopwords and get stems for content words from raw
text input.
* texting - readable text compression.
* doctor - emulation of Weizenbaum's Doctor program.
* chinese - basic translation of English to Chinese in simplified
or traditional characters.
* querying - rewrite English questions as SQL queries for a Soviet
military aircraft database.
* marking - rewrite English text from the Web with shallow XML markup
* name - extract mostly English personal names from text
* disambig - disambiguation of phrases with WordNet concept information.
* chemic - recognition of chemical names in text
These show just a few of the many things PyElly can do for you. They also
serve as a basis for comprehensive software integration testing. You may
use any of them as models for building your own PyElly applications.
PyElly is free software released under a BSD open-source license for
educational and other uses. Be advised that the current software and
documentation is still evolving, although releases after v1.2 should be
more stable than preceding releases.

New versions will be assigned for non-cosmetic changes in PyElly code. This will
often require regenerating any previously saved *.elly.bin files to ensure
correct operation. Changes only to PyElly example application definition files,
unit testing input or key files, and PyElly documentation will be made from time
to time, but these will leave version numbers the same, if they are no other
changes. Check Github for the latest files. The dates above are for the initial
release of a version, not the most recent update,
