Update unstructured requirement from <0.15 to <0.16 in /topic/machine-learning/llm-langchain

[dependabot]

Updates the requirements on unstructured to permit the latest version.

Release notes

Sourced from unstructured's releases.

0.15.0

Enhancements

• Improve text clearing process in email partitioning. Updated the email partitioner to remove both =\n and =\r\n characters during the clearing process. Previously, only =\n characters were removed.
• Bump unstructured.paddleocr to 2.8.0.1.
• Refine HTML parser to accommodate block element nested in phrasing. HTML parser no longer raises on a block element (e.g. <p>, <div>) nested inside a phrasing element (e.g. <strong> or <cite>). Instead it breaks the phrasing run (and therefore element) at the block-item start and begins a new phrasing run after the block-item. This is consistent with how the browser determines element boundaries in this situation.
• Install rewritten HTML parser to fix 12 existing bugs and provide headroom for refinement and growth. A rewritten HTML parser resolves a collection of outstanding bugs with HTML partitioning and provides a firm foundation for further elaborating that important partitioner.
• CI check for dependency licenses Adds a CI check to ensure dependencies are appropriately licensed.

Features

• Add support for specifying OCR language to partition_pdf(). Extend language specification capability to PaddleOCR in addition to TesseractOCR. Users can now specify OCR languages for both OCR engines when using partition_pdf().
• Add AstraDB source connector Adds support for ingesting documents from AstraDB.

Fixes

• Remedy error on Windows when nltk binaries are downloaded. Work around a quirk in the Windows implementation of tempfile.NamedTemporaryFile where accessing the temporary file by name raises PermissionError.
• Move Astra embedded_dimension to write config

0.14.10

Enhancements

• Update unstructured-client dependency Change unstructured-client dependency pin back to greater than min version and updated tests that were failing given the update.
• .doc files are now supported in the arm64 image.. libreoffice24 is added to the arm64 image, meaning .doc files are now supported. We have follow on work planned to investigate adding .ppt support for arm64 as well.
• Add table detection metrics: recall, precision and f1.
• Remove unused _with_spans metrics.

Features

Add Object Detection Metrics to CI Add object detection metrics (average precision, precision, recall and f1-score) implementations.

Fixes

• Fix counting false negatives and false positives in table structure evaluation.
• Fix Slack CI test Change channel that Slack test is pointing to because previous test bot expired
• Remove NLTK download Removes nltk.download in favor of downloading from an S3 bucket we host to mitigate CVE-2024-39705

0.14.9

Enhancements

• Added visualization and OD model result dump for PDF In PDF hi_res strategy the analysis parameter can be used to visualize the result of the OD model and dump the result to a file. Additionally, the visualization of bounding boxes of each layout source is rendered and saved for each page.
• partition_docx() distinguishes "file not found" from "not a ZIP archive" error. partition_docx() now provides different error messages for "file not found" and "file is not a ZIP archive (and therefore not a DOCX file)". This aids diagnosis since these two conditions generally point in different directions as to the cause and fix.
