pybiber: A comprehensive Python package for linguistic feature extraction and Multi-Dimensional Analysis
========================================================================================================
|pypi| |pypi_downloads| |tests|

The pybiber package provides tools for extracting 67 lexicogrammatical and functional features described by `Biber (1988) <https://books.google.com/books?id=CVTPaSSYEroC&dq=variation+across+speech+and+writing&lr=&source=gbs_navlinks_s>`_ and widely used for text-type, register, and genre classification tasks in corpus linguistics.

**Key Features:**

- **67 Linguistic Features**: Automated extraction of tense markers, pronouns, subordination patterns, modal verbs, and more
- **Multi-Dimensional Analysis**: Complete implementation of Biber's MDA methodology for register analysis
- **Principal Component Analysis**: Alternative dimensionality reduction approaches with visualization tools
- **High Performance**: Built on `spaCy <https://spacy.io/models>`_ and `Polars <https://docs.pola.rs/>`_ for efficient text processing
- **End-to-End Pipeline**: From raw text files to statistical analysis in just a few lines of code
- **Comprehensive Visualization**: Built-in plotting functions for exploratory data analysis

**Applications:**

- Register and genre analysis in corpus linguistics
- Text classification and machine learning preprocessing  
- Diachronic language change studies
- Cross-linguistic variation research
- Academic writing analysis and pedagogical applications
- Stylometric analysis and authorship attribution

The package uses `spaCy <https://spacy.io/models>`_ part-of-speech tagging and dependency parsing with `Polars <https://docs.pola.rs/>`_ DataFrames for high-performance analytics.

**Accuracy Note**: Feature extraction builds from probabilistic taggers, so accuracy depends on model quality. Texts with irregular spellings or non-standard punctuation may produce unreliable outputs unless taggers are specifically tuned for those domains.

See `the documentation <https://browndw.github.io/pybiber>`_ for comprehensive guides and API reference.

See `pseudobibeR <https://cran.r-project.org/web/packages/pseudobibeR/index.html>`_ for the R implementation.

Quick Start
-----------

**One-line processing** from a folder of text files:

.. code-block:: python

    import pybiber as pb

    # Process all .txt files in a directory
    pipeline = pb.PybiberPipeline(model="en_core_web_sm")
    features = pipeline.run_from_folder("path/to/texts")

**Multi-Dimensional Analysis** with visualization:

.. code-block:: python

    # Create analyzer for statistical analysis
    analyzer = pb.BiberAnalyzer(features)
    
    # Perform MDA and generate scree plot
    mda_results = analyzer.mda()
    analyzer.mdaviz_screeplot()
    
    # Plot group means by dimension
    analyzer.mdaviz_groupmeans(grouping_var="register")

Installation
------------

You can install the released version of pybiber from `PyPI <https://pypi.org/project/pybiber/>`_:

.. code-block:: install-pybiber

    pip install pybiber

Install a `spaCY model <https://spacy.io/usage/models#download>`_:

.. code-block:: install-model

    python -m spacy download en_core_web_sm

Usage
-----

**Data Requirements**

The pybiber package works with corpora structured as DataFrames with:
- ``doc_id`` column: Unique document identifiers  
- ``text`` column: Raw text content

This follows conventions from `readtext <https://readtext.quanteda.io/articles/readtext_vignette.html>`_ and `quanteda <https://quanteda.io/>`_.

**Step-by-Step Workflow**

1. **Import libraries and load spaCy model**:

.. code-block:: python

    import spacy
    import pybiber as pb
    from pybiber.data import micusp_mini  # Sample corpus
    
    nlp = spacy.load("en_core_web_sm")

2. **Parse corpus with spaCy**:

.. code-block:: python

    # Parse texts to extract linguistic annotations (modern approach)
    processor = pb.CorpusProcessor()
    tokens_df = processor.process_corpus(micusp_mini, nlp)

3. **Extract Biber features**:

.. code-block:: python

    # Aggregate 67 linguistic features per document  
    features_df = pb.biber(tokens_df)

4. **Advanced Analysis** (optional):

.. code-block:: python

    # Statistical analysis and visualization
    analyzer = pb.BiberAnalyzer(features_df)
    
    # Multi-Dimensional Analysis
    mda_results = analyzer.mda()
    
    # Principal Component Analysis
    pca_results = analyzer.pca()
    
    # Visualization options
    analyzer.mdaviz_screeplot()           # Eigenvalue plot
    analyzer.pcaviz_contrib()             # Feature contributions
    analyzer.mdaviz_groupmeans(group_var="genre")  # Group comparisons

**Pipeline Convenience Functions**

For streamlined processing, use the high-level pipeline:

.. code-block:: python

    from pybiber import PybiberPipeline
    
    pipeline = PybiberPipeline(model="en_core_web_sm", disable_ner=True)
    
    # From folder of .txt files
    features_df = pipeline.run_from_folder("/path/to/texts")
    
    # From in-memory corpus
    features_df, tokens_df = pipeline.run(corpus_df, return_tokens=True)
    
    # One-liner convenience functions
    features_df = pb.run_biber_from_folder("/path/to/texts")
    features_df = pb.run_biber(corpus_df)

Feature Categories
------------------

The package extracts 67 linguistic features across 16 categories:

- **Tense & Aspect**: Past tense, perfect aspect, present tense
- **Adverbials**: Place and time adverbials  
- **Pronouns**: 1st/2nd/3rd person, demonstrative, indefinite pronouns
- **Questions**: Direct wh-questions
- **Nominal Forms**: Nominalizations, gerunds, nouns
- **Passives**: Agentless and by-passives
- **Stative Forms**: *be* as main verb, existential *there*
- **Subordination**: 18 different clause types (that-clauses, wh-clauses, infinitives, relatives, etc.)
- **Modification**: Prepositional phrases, attributive/predicative adjectives, adverbs
- **Lexical Specificity**: Type-token ratio, word length
- **Lexical Classes**: Conjuncts, hedges, amplifiers, emphatics, discourse particles
- **Modals**: Possibility, necessity, and predictive modals
- **Specialized Verbs**: Public, private, suasive verbs
- **Reduced Forms**: Contractions, deletions, split constructions
- **Coordination**: Phrasal and clausal coordination
- **Negation**: Synthetic and analytic negation

See the `full feature list <https://browndw.github.io/pybiber/feature-categories.html>`_ for detailed descriptions.

Performance & Requirements
--------------------------

**System Requirements:**
- Python 3.10+
- spaCy model with POS tagging and dependency parsing (e.g., ``en_core_web_sm``)

**Performance Notes:**
- Built on Polars for fast DataFrame operations
- Supports multiprocessing for large corpora
- Memory-efficient processing with configurable batch sizes
- Processing time: ~20-30 seconds for small corpora (e.g., 500 documents)

You may reproduce and distribute copies of the\n              Work or Derivative Works thereof in any medium, with or without\n              modifications, and in Source or Object form, provided that You\n              meet the following conditions:\n        \n              (a) You must give any other recipients of the Work or\n                  Derivative Works a copy of this License; and\n        \n              (b) You must cause any modified files to carry prominent notices\n                  stating that You changed the files; and\n        \n              (c) You must retain, in the Source form of any Derivative Works\n                  that You distribute, all copyright, patent, trademark, and\n                  attribution notices from the Source form of the Work,\n                  excluding those notices that do not pertain to any part of\n                  the Derivative Works; and\n        \n              (d) If the Work includes a \"NOTICE\" text file as part of its\n                  distribution, then any Derivative Works that You distribute must\n                  include a readable copy of the attribution notices contained\n                  within such NOTICE file, excluding those notices that do not\n                  pertain to any part of the Derivative Works, in at least one\n                  of the following places: within a NOTICE text file distributed\n                  as part of the Derivative Works; within the Source form or\n                  documentation, if provided along with the Derivative Works; or,\n                  within a display generated by the Derivative Works, if and\n                  wherever such third-party notices normally appear. The contents\n                  of the NOTICE file are for informational purposes only and\n                  do not modify the License. You may add Your own attribution\n                  notices within Derivative Works that You distribute, alongside\n                  or as an addendum to the NOTICE text from the Work, provided\n                  that such additional attribution notices cannot be construed\n                  as modifying the License.\n        \n              You may add Your own copyright statement to Your modifications and\n              may provide additional or different license terms and conditions\n              for use, reproduction, or distribution of Your modifications, or\n              for any such Derivative Works as a whole, provided Your use,\n              reproduction, and distribution of the Work otherwise complies with\n              the conditions stated in this License.\n        \n           5. Submission of Contributions. Unless You explicitly state otherwise,\n              any Contribution intentionally submitted for inclusion in the Work\n              by You to the Licensor shall be under the terms and conditions of\n              this License, without any additional terms or conditions.\n              Notwithstanding the above, nothing herein shall supersede or modify\n              the terms of any separate license agreement you may have executed\n              with Licensor regarding such Contributions.\n        \n           6. Trademarks. This License does not grant permission to use the trade\n              names, trademarks, service marks, or product names of the Licensor,\n              except as required for reasonable and customary use in describing the\n              origin of the Work and reproducing the content of the NOTICE file.\n        \n           7. Disclaimer of Warranty. Unless required by applicable law or\n              agreed to in writing, Licensor provides the Work (and each\n              Contributor provides its Contributions) on an \"AS IS\" BASIS,\n              WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or\n              implied, including, without limitation, any warranties or conditions\n              of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A\n              PARTICULAR PURPOSE. You are solely responsible for determining the\n              appropriateness of using or redistributing the Work and assume any\n              risks associated with Your exercise of permissions under this License.\n        \n           8. Limitation of Liability. In no event and under no legal theory,\n              whether in tort (including negligence), contract, or otherwise,\n              unless required by applicable law (such as deliberate and grossly\n              negligent acts) or agreed to in writing, shall any Contributor be\n              liable to You for damages, including any direct, indirect, special,\n              incidental, or consequential damages of any character arising as a\n              result of this License or out of the use or inability to use the\n              Work (including but not limited to damages for loss of goodwill,\n              work stoppage, computer failure or malfunction, or any and all\n              other commercial damages or losses), even if such Contributor\n              has been advised of the possibility of such damages.\n        \n           9. Accepting Warranty or Additional Liability. While redistributing\n              the Work or Derivative Works thereof, You may choose to offer,\n              and charge a fee for, acceptance of support, warranty, indemnity,\n              or other liability obligations and/or rights consistent with this\n              License. However, in accepting such obligations, You may act only\n              on Your own behalf and on Your sole responsibility, not on behalf\n              of any other Contributor, and only if You agree to indemnify,\n              defend, and hold each Contributor harmless for any liability\n              incurred by, or claims asserted against, such Contributor by reason\n              of your accepting any such warranty or additional liability.\n        \n           END OF TERMS AND CONDITIONS\n        \n           APPENDIX: How to apply the Apache License to your work.\n        \n              To apply the Apache License to your work, attach the following\n              boilerplate notice, with the fields enclosed by brackets \"[]\"\n              replaced with your own identifying information.

We also recommend that a\n              file or class name and description of purpose be included on the\n              same \"printed page\" as the copyright notice for easier\n              identification within third-party archives.\n        \n           Copyright [yyyy] [name of copyright owner]\n        \n           Licensed under the Apache License, Version 2.0 (the \"License\");\n           you may not use this file except in compliance with the License.\n           You may obtain a copy of the License at\n        \n               http://www.apache.org/licenses/LICENSE-2.0\n        \n           Unless required by applicable law or agreed to in writing, software\n           distributed under the License is distributed on an \"AS IS\" BASIS,\n           WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\n           See the License for the specific language governing permissions and\n           limitations under the License.\n        ",
