CoNLL-2003 is a named entity recognition dataset released as a part of CoNLL-2003 shared task: language-independent named entity recognition. The data consists of eight files covering two languages: English and German. For each of the languages there is a training file, a development file, a test file and a large file with unannotated data.

SciERC dataset is a collection of 500 scientific abstract annotated with scientific entities, their relations, and coreference clusters. The abstracts are taken from 12 AI conference/workshop proceedings in four AI communities, from the Semantic Scholar Corpus. SciERC extends previous datasets in scientific articles SemEval 2017 Task 10 and SemEval 2018 Task 7 by extending entity types, relation types, relation coverage, and adding cross-sentence relations using coreference links.

HAREM, an initiative by Linguateca, boasts a Golden Collection—a meticulously curated repository of annotated Portuguese texts. This resource serves as a pivotal benchmark for evaluating systems in recognizing mentioned entities within documents. It stands as a cornerstone, supporting advancements and innovations in Portuguese language processing research, providing a comprehensive foundation for evaluating system performances and fostering ongoing developments in this domain.

The MiniHAREM, a reiteration of the 2005 evaluation, used the same methodology and platform. Held from April 3rd to 5th, 2006, it offered participants a 48-hour window to annotate, verify, and submit text collections. Results are available, and the collection used is accessible. Participant lists, submitted outputs, and updated guidelines are provided. Additionally, the HAREM format checker ensures compliance with MiniHAREM directives. Information for the HAREM Meeting, open for registration until June 15th after the Linguateca Summer School in the University of Porto, is also available.
The dataset used to pre-train NuNER from the NuNER: Entity Recognition Encoder Pre-training via LLM-Annotated Data
This dataset was taken from the SIGARRA information system at the University of Porto (UP). Every organic unit has its own domain and produces academic news. We collected a sample of 1000 news, manually annotating 905 using the Brat rapid annotation tool. This dataset consists of three files. The first is a CSV file containing news published between 2016-12-14 and 2017-03-01. The second file is a ZIP archive containing one directory per organic unit, with a text file and an annotations file per news article. The third file is an XML containing the complete set of news in a similar format to the HAREM dataset format. This dataset is particularly adequate for training named entity recognition models.

The Second HAREM was an evaluation exercise in Portuguese Named Entity Recognition. It aims to refine text annotation processes, building on the First HAREM. Challenges include adapting guidelines for new texts and establishing a unified document with directives from both editions.
