A large-scale benchmark for Scientific Introduction Generation (SciIG) — generating coherent, citation-grounded introductions from a paper's title, abstract, and related work.

As researchers increasingly adopt LLMs as writing assistants, generating high-quality research paper introductions remains both challenging and essential. We benchmark Scientific Introduction Generation (SciIG), evaluating how well LLMs produce coherent introductions from titles, abstracts, and related works in the Machine Learning domain. Curating new datasets from NAACL 2025 and ICLR 2025 papers, we assess five state-of-the-art models — open-source (DeepSeek-V3, Gemma-3-12B, LLaMA-4 Maverick, Mistral-Small-3.1) and closed-source (GPT-4o) — across lexical overlap, semantic similarity, content coverage, faithfulness, consistency, citation correctness, and narrative quality. Our framework combines automated metrics with LLM-as-a-judge evaluation. LLaMA-4 Maverick shows the strongest overall performance, particularly on lexical overlap, content coverage, citation quality and perplexity; three-shot prompting outperforms fewer-shot approaches more than 50% of the time on formula-based metrics and consistently on human-evaluation metrics. These findings offer practical insight into building research-writing assistants and set realistic expectations for LLM-assisted academic writing.
SciIG establishes a common experimental and evaluation foundation for a task that has, until now, been under-benchmarked in the LLM era.
A systematic benchmark for research-paper introduction generation in the LLM era, with a shared experimental and evaluation foundation.
Formula-based automatic metrics, LLM-as-a-judge metrics, and human evaluation — capturing both surface-level and higher-order qualities like faithfulness, consistency, and writing quality.
PDF text extraction, LLM-assisted citation identification, and structured retrieval of cited titles and abstracts via the Semantic Scholar API — yielding 3,900 samples with a 94.0% citation-resolution rate.
A systematic exploration of prompting strategies, complemented by a human-evaluation study on a subset of samples, giving practical guidance for LLM-assisted scientific writing.
Papers from NAACL'25 and ICLR'25 are retrieved and parsed (Phase I), their citations extracted and mapped to reference titles (Phase II), and each reference enriched with Semantic Scholar metadata (Phase III). Each sample pairs (Title, Abstract, Related Work) with the published introduction as target.
Five models on NAACL 2025 (800 samples) with the Elaborate strategy. LLaMA-4 Maverick emerges as the overall front-runner, leading on lexical overlap, content coverage, citation quality, and perplexity. Best value per row is highlighted. Lower perplexity is better.
Full per-metric definitions, formulae, and the ICLR 2025 results appear in the paper. Values shown are for the NAACL 2025 set under the Elaborate prompt.
Generations for one NAACL 2025 paper — "Zero-Shot Keyphrase Generation: Investigating Specialized Instructions and Multi-Sample Aggregation on Large Language Models" — with the ground truth and three LLaMA-4 configurations plus GPT-4o.
The seven prompts used to elicit introductions. Runtime values appear as {placeholders}: {title} and {abstract} are the target paper's; {cited_nodes_pretty} is the JSON-formatted related-papers block with APA citations. Few-shot prompts prepend 1–3 held-out examples to the Elaborate prompt.
