+# Introduction
+
+**LongBench** is the first comprehensive dataset for multi-language, multi-task, and comprehensive assessment of **long text understanding** capabilities of large language models. In the context of the widespread attention to the multi-language capabilities of large models, LongBench includes different languages (Chinese and English) to provide a more comprehensive evaluation of the large models' multi-language capabilities in long texts. In addition, LongBench consists of twenty different tasks, covering key long-text application scenarios such as single-document QA, multi-document QA, summaries, few-shot learning, code completion, and synthesis tasks.
+
+We are fully aware of the potentially high costs involved in the model evaluation process, especially in the context of long-text scenarios (such as manual annotation costs or API call costs). Therefore, we have adopted a fully automated evaluation method, aimed at measuring and evaluating the model's ability to understand long texts at the lowest cost and most effectively.
+
+LongBench includes 13 English tasks, 5 Chinese tasks, and 2 code tasks, with the average length of most tasks ranging from 5k to 15k. From the main task categories, LongBench includes six types of tasks, namely multi-document QA, single-document QA, summaries, Few-shot learning, synthetic tasks, and code completion.

+# Task construction
+
+> Note: For all tasks constructed from existing datasets, we use data from the validation or test set of the existing dataset (except for VCSUM).
+
+- The tasks of [HotpotQA](https://hotpotqa.github.io/), [2WikiMultihopQA](https://aclanthology.org/2020.coling-main.580/), [Musique](https://arxiv.org/abs/2108.00573), and [DuReader](https://github.com/baidu/DuReader) are built based on the original datasets and processed to make them suitable for long text evaluation. Specifically, for questions in the validation set, we select the evidence passage that contains the answer and several distracting articles. These articles together with the original question constitute the input of the related tasks.
+- The tasks of MultiFiedQA-zh and MultiFieldQA-en consist of long-text data from about 10 sources, including Latex papers, judicial documents, government work reports, and PDF documents indexed by Google. For each long text, we invite several PhD and master students to annotate, i.e., to ask questions based on the long text and give the correct answers. To better automate evaluation, we require the annotators to ask questions with definitive answers as much as possible.
+- The tasks of [NarrativeQA](https://arxiv.org/pdf/1712.07040.pdf), [Qasper](https://arxiv.org/pdf/2105.03011.pdf), [GovReport](https://arxiv.org/pdf/2104.02112.pdf), and [QMSum](https://arxiv.org/pdf/2104.05938.pdf) directly use the data provided by the original papers. In the specific construction, we use the template provided by [ZeroSCROLLS](https://www.zero.scrolls-benchmark.com/) to convert the corresponding data into pure text input.
+- The [VCSUM](https://arxiv.org/abs/2305.05280) task is built based on the original dataset, and we have designed a corresponding template to convert the corresponding data into pure text input.
+- The tasks of [TriviaQA](https://nlp.cs.washington.edu/triviaqa/) and [NQ](https://ai.google.com/research/NaturalQuestions/) are constructed in the manner of [CoLT5](https://arxiv.org/abs/2303.09752), which provides several examples of question and answering based on documents, and requires the language model to answer related questions based on new documents.
+- The tasks of [TREC](https://aclanthology.org/C02-1150.pdf) and [LSHT](http://tcci.ccf.org.cn/conference/2014/dldoc/evatask6.pdf) are built based on the original datasets. For each question in the validation set, we sample several data from the training set to form few-shot examples. These examples together with the questions in the validation set constitute the input for this task.
+- The PassageRetrieval-en task is constructed based on English Wikipedia. For each piece of data, we randomly sample 30 paragraphs from English Wikipedia and select one for summarization (using GPT3.5 Turbo). The task requires the model to specify which original paragraph the summary corresponds to.
+- The PassageCount task is constructed based on the English wiki. For each piece of data, we randomly sample several passages from English Wikipedia, repeat each paragraph at random several times, and finally shuffle the paragraphs at random. This task requires the model to determine how many paragraphs are not repeated in a given number of paragraphs.
+- The PasskeyRetrieval-zh task is constructed based on [C4](https://arxiv.org/abs/1910.10683). For each piece of data, we randomly sample several Chinese paragraphs from C4 and select one of them for summary (using GPT3.5 Turbo). This task requires the model to give the original paragraph to which the summary should correspond.
+- For the [LCC](https://arxiv.org/abs/2306.14893) task, we sample from the original code completion dataset. In the [RepoBench-P](https://arxiv.org/abs/2306.03091) task, we select the most challenging XF-F (Cross-File-First) setting from the original dataset and refer to the Oracle-Filled scenario in the original text. For each original piece of data, we randomly extract multiple cross-file code snippets, including the effective cross-file code snippet (gold snippet), and concatenate them as input, requiring the model to use the effective cross-file code to complete the current file's code.
