USB: A Unified Summarization Benchmark Across Tasks and Domains

This benchmark contains labeled datasets for 8 text summarization based tasks given below. The labeled datasets are created by collecting manual annotations on top of Wikipedia articles from 6 different domains.

Task	Description	Code snippet
Extractive Summarization	Highlight important sentences in the source article	`load_dataset("kundank/usb","extractive_summarization")`
Abstractive Summarization	Generate a summary of the source	`load_dataset("kundank/usb","abstractive_summarization")`
Topic-based Summarization	Generate a summary of the source focusing on the given topic	`load_dataset("kundank/usb","topicbased_summarization")`
Multi-sentence Compression	Compress selected sentences into a one-line summary	`load_dataset("kundank/usb","multisentence_compression")`
Evidence Extraction	Surface evidence from the source for a summary sentence	`load_dataset("kundank/usb","evidence_extraction")`
Factuality Classification	Predict the factual accuracy of a summary sentence with respect to provided evidence	`load_dataset("kundank/usb","factuality_classification")`
Unsupported Span Prediction	Identify spans in a summary sentence which are not substantiated by the provided evidence	`load_dataset("kundank/usb","unsupported_span_prediction")`
Fixing Factuality	Rewrite a summary sentence to remove any factual errors or unsupported claims, with respect to provided evidence	`load_dataset("kundank/usb","fixing_factuality")`

Additionally, to load the full set of collected annotations which were leveraged to make the labeled datasets for above tasks, use the command: load_dataset("kundank/usb","all_annotations")

Trained models

We fine-tuned Flan-T5-XL models on the training set of each task in the benchmark. They are available at the links given below:
