v0.7.0: Manage events without agendas in the summarisation workflow

[bakaburg1]

This pull request includes a series of enhancements and fixes that improve the transcript summarization workflow, add new functionality for entity extraction, and ensure better support for various transcript formats. The changes also address code quality and documentation to provide a more robust and user-friendly experience.

Breaking:

• Replaced event_audience with audience as argument name for consistency across the framework. Before, some functions used the first and some the second term (Commit: 644fb29).

Enhancements:

• Workflow Enhancement: Added support for summarizing meetings without an agenda in the workflow. Before, the full workflow function was designed to only work with long meetings organized in sub-talks described by an agenda. (Commit: 644fb29).
• Entity Extraction Functionality: Introduced the entity_extractor function to identify and extract entities such as people, acronyms, organizations, and concepts from a text, which can be particularly useful for building vocabularies for LLMs from event descriptions or transcripts (Commit: ae4fc3c).
• Agenda Management: Added the ability to manage deviations from the expected agenda, allowing the LLM to add talks not described in the expected agenda, enhancing the flexibility of the summarization process (Commit: 40f7620).
• Support for MS Teams VTT Files: Implemented support for importing transcripts from MS Teams VTT files, which do not follow the standard VTT specification (Commit: cfa9673).
• Output Quality Improvements: Utilized the styler package to enhance the readability of generated agendas and unformatted summary outputs, contributing to better readability and user experience (Commit: 194b8c8).

Fixes:

• Agenda Generation Bug: Resolved an issue where the agenda generation was creating infinite unnamed speaker lists, exhausting the context window (Commit: bfc5597).

Dependencies:

• Styler Package Addition: Added the styler package and its dependencies to the project, which is used to improve the formatting of the generated outputs (Commit: e88a6bd).

In the code's gentle weave, a change was made,
With careful paws, the paths were laid.
From VTT to summaries so bright,
A rabbit hopped through code, by night.
Celebrate each line, for through the maze,
We find our way, in the code's embrace.

Parameter renaming from event_audience to audience is correctly implemented. The function effectively manages agendas and output files.

The addition of the diarization_instructions parameter is consistent with PR objectives and is correctly implemented in the function.

863-937: The new entity_extractor function is well-designed and correctly implements entity extraction with support for multiple types and JSON output. This enhances LLM interaction significantly.

R/data_management.R (2)

1002-1008: > 📝 NOTE

This review was outside the diff hunks and was mapped to the diff hunk with the greatest overlap. Original lines [1005-1024]

The renaming of the event_audience parameter to audience in the speech_to_summary_workflow function aligns with the PR's objective to standardize parameter names across the framework. This change should be clearly documented in the function's docstring to avoid confusion for users who are familiar with the previous parameter name.

1293-1334: > 📝 NOTE

This review was outside the diff hunks and was mapped to the diff hunk with the greatest overlap. Original lines [1268-1331]

The logic for handling the agenda parameter in the speech_to_summary_workflow function is robust, providing clear error messages and handling various user input scenarios effectively. However, the user interaction flow could be improved by providing more detailed instructions or options in the interactive menu. Additionally, consider adding logging or comments to clarify the steps involved in agenda generation and summarization.
