Hashformers is a framework for hashtag segmentation with transformers.

Last update: Nov 09, 2022

Overview

Hashtag segmentation is the task of automatically inserting the missing spaces between the words in a hashtag.

Hashformers applies Transformer models to hashtag segmentation. It is built on top of the transformers library and the lm-scorer and mlm-scoring packages.

Try it right now on Google Colab.

Paper: Zero-shot hashtag segmentation for multilingual sentiment analysis

Basic usage

from hashformers import WordSegmenter

ws = WordSegmenter(
    segmenter_model_name_or_path="gpt2",
    reranker_model_name_or_path="bert-base-uncased",
    use_reranker=True
)

segmentations = ws.segment([
    "#myoldphonesucks",
    "#latinosinthedeepsouth",
    "#weneedanationalpark",
    "#LandoftheLost",
    "#icecold",
    "#Heartbreaker",
    "#TheRiseGuys"
])

print(segmentations)

# ['my old phone sucks',
# 'latinos in the deep south',
# 'we need a national park',
# 'Land of the Lost',
# 'ice cold',
# 'Heartbreaker',
# 'The Rise Guys']

Installation

Installation steps are described on this notebook. A Docker image is coming soon.

Examples

Applications of hashtag segmentation to tweet sentiment analysis and the automatic translation of tweets can be found on the examples folder.

Contributing

Pull requests are welcome! We need to improve on the documentation and code quality of this repository. It's also a good idea to implement more sophisticated ensembling techniques. Read our paper for more details on the inner workings of our framework.

Version 0.15.3

Released 2019-05-14

Properly handle multi-line header folding in development server in Python 2.7. (:issue:1080)

Restore the response argument to :exc:~exceptions.Unauthorized. (:pr:1527)

:exc:~exceptions.Unauthorized doesn't add the WWW-Authenticate header if www_authenticate is not given. (:issue:1516)

The default URL converter correctly encodes bytes to string rather than representing them with b''. (:issue:1502)

Fix the filename format string in :class:~middleware.profiler.ProfilerMiddleware to correctly handle float values. (:issue:1511)

Update :class:~middleware.lint.LintMiddleware to work on Python 3. (:issue:1510)

The debugger detects cycles in chained exceptions and does not time out in that case. (:issue:1536)

When running the development server in Docker, the debugger security pin is now unique per container.

Version 0.15.2

Released 2019-04-02

Rule code generation uses a filename that coverage will ignore. The previous value, "generated", was causing coverage to fail. (:issue:1487)

The test client removes the cookie header if there are no persisted cookies. This fixes an issue introduced in 0.15.0 where the cookies from the original request were used for redirects, causing functions such as logout to fail. (:issue:1491)

The test client copies the environ before passing it to the app, to prevent in-place modifications from affecting redirect requests. (:issue:1498)

The "werkzeug" logger only adds a handler if there is no handler configured for its level in the logging chain. This avoids double logging if other code configures logging first. (:issue:1492)

Bump cryptography from 2.8 to 3.3.2
Bumps cryptography from 2.8 to 3.3.2.

Changelog

Sourced from cryptography's changelog.

3.3.2 - 2021-02-07

* **SECURITY ISSUE:** Fixed a bug where certain sequences of ``update()`` calls when symmetrically encrypting very large payloads (>2GB) could result in an integer overflow, leading to buffer overflows. *CVE-2020-36242* **Update:** This fix is a workaround for *CVE-2021-23840* in OpenSSL, fixed in OpenSSL 1.1.1j. .. _v3-3-1:
3.3.1 - 2020-12-09

Re-added a legacy symbol causing problems for older pyOpenSSL users.

.. _v3-3:

3.3 - 2020-12-08

* **BACKWARDS INCOMPATIBLE:** Support for Python 3.5 has been removed due to low usage and maintenance burden. * **BACKWARDS INCOMPATIBLE:** The :class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` and :class:`~cryptography.hazmat.primitives.ciphers.aead.AESGCM` now require 64-bit to 1024-bit (8 byte to 128 byte) initialization vectors. This change is to conform with an upcoming OpenSSL release that will no longer support sizes outside this window. * **BACKWARDS INCOMPATIBLE:** When deserializing asymmetric keys we now raise ``ValueError`` rather than ``UnsupportedAlgorithm`` when an unsupported cipher is used. This change is to conform with an upcoming OpenSSL release that will no longer distinguish between error types. * **BACKWARDS INCOMPATIBLE:** We no longer allow loading of finite field Diffie-Hellman parameters of less than 512 bits in length. This change is to conform with an upcoming OpenSSL release that no longer supports smaller sizes. These keys were already wildly insecure and should not have been used in any application outside of testing. * Updated Windows, macOS, and ``manylinux`` wheels to be compiled with OpenSSL 1.1.1i. * Python 2 support is deprecated in ``cryptography``. This is the last release that will support Python 2. * Added the :meth:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey.recover_data_from_signature` function to :class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey` for recovering the signed data from an RSA signature. .. _v3-2-1:
