# The idea behind this method is "give me a collection of texts,
|
|
# and I'll handle the summarization to the best of my capabilities.".
|
|
# It's important to emphasize the "collection of texts" part, which implies
|
|
# it's not tied to any model and expects the "content" to be a hash instead.
|
|
#
|
|
# @param content { Hash } - Includes the content to summarize, plus additional
|
|
# context to help the strategy produce a better result. Keys present in the content hash:
|
|
# - resource_path (optional): Helps the strategy build links to the content in the summary (e.g. "/t/-/:topic_id/POST_NUMBER")
|
|
# - content_title (optional): Provides guidance about what the content is about.
|
|
# - contents (required): Array of hashes with content to summarize (e.g. [{ poster: "asd", id: 1, text: "This is a text" }])
|
|
# All keys are required.
|
|
# @param &on_partial_blk { Block - Optional } - If the strategy supports it, the passed block
|
|
# will get called with partial summarized text as its generated.
|
|
#
|
|
# @returns { Hash } - The summarized content, plus chunks if the content couldn't be summarized in one pass. Example:
|
|
# {
|
|
# summary: "This is the final summary",
|
|
# chunks: [
|
|
# { ids: [topic.first_post.post_number], summary: "this is the first chunk" },
|
|
# { ids: [post_1.post_number, post_2.post_number], summary: "this is the second chunk" },

# ],
