Iris Species Dataset
The Iris dataset was used in R.A. Fisher's classic 1936 paper, The Use of Multiple Measurements in Taxonomic Problems, and can also be found on the UCI Machine Learning Repository.
It includes three iris species with 50 samples each as well as some properties about each flower. One flower species is linearly separable from the other two, but the other two are not linearly separable from each other.
The dataset is taken from UCI Machine Learning Repository's… See the full description on the dataset page: https://huggingface.co/datasets/scikit-learn/iris.IRFL

NASA-IR benchmark
NASA SMD and IBM Research developed a domain-specific information retrieval benchmark, NASA-IR, spanning almost 500 question-answer pairs related to the Earth science, planetary science, heliophysics, astrophysics, and biological physical sciences domains. Specifically, we sampled a set of 166 paragraphs from AGU, AMS, ADS, PMC, and PubMed and manually annotated with 3 questions that are answerable from each of these paragraphs, resulting in 498 questions. We used… See the full description on the dataset page: https://huggingface.co/datasets/nasa-impact/nasa-smd-IR-benchmark.IRPAPERS

Recipe Cleaned Dataset
Dataset Summary
This dataset is a structured and cleaned collection of recipe data derived from the Food.com Recipes and Interactions dataset. It is designed for ingredient-based personalization, machine learning training, and interactive recommendation systems. The dataset integrates a hierarchical ingredient taxonomy, standardized nutrition information, and categorical metadata (e.g., diet tags, cuisine attributes, region) to support downstream… See the full description on the dataset page: https://huggingface.co/datasets/Iris314/recipe-cleaned.scraped-hotel-reviewsiris-tabularscikit_irisirs-articlesopencorporates_IRS990_EIN_matched_organizationsExternal Dataset Credits: OpenCorporates Limited
Dataset containing all IRS 990 organizations by EIN for 2022-2023 and their matched opencorporates unique identifiers (company_number). This allows researchers to combine IRS990 data with opencorporates state-level company data. If an organization 0 for the match confidence, that EIN was tested and did not match any opencorporates entities. All 990-CN, EZ, and PF organizations for 2022-2023 were tested.

Our data is mostly the same as EmbedLLM's. Specially, we applied a majority vote to consolidate multiple answers from a model to the same query.
If the number of 0s and 1s is the same, we prioritize 1.
