bidCorpus_NER_keyphrase

This dataset is composed of texts from the "object" section of bidding notices. The dataset is labeled with two types of named entities, following the IOB (Inside-Outside-Beginning) format.

1. Object of the bid: Refers to the item to be acquired or the service to be contracted. The tags can be "B-OBJECT" (beginning of the entity) and "I-OBJECT" (continuation of the entity).
2. Municipality of the managing unit: Indicates the location of the entity responsible for the bid. The tags can be "B-MUNICIPALITY" (beginning of the entity) and "I-MUNICIPALITY" (continuation of the entity).

This dataset is intended for training named entity recognition (NER) models, which are used to automatically identify and classify these entities within the texts. The labeled structure of the dataset facilitates the task of teaching models to distinguish between different types of relevant information in the bidding notices. The dataset follows the IOB format for named entity recognition, with entities labeled as either part of the object of the bid or the municipality of the managing unit.

bidCorpus_gold

This dataset consists of texts from the qualification section of bidding notices. Annotated by experts in public procurement, the dataset is multilabel and contains seven labels that indicate possible signs of fraud in public contracts.

1. Certidão de Protesto: Verification of any protests in the company's name.
2. Certificado de Boas Práticas: Assessment of adherence to recommended practices in the sector.
3. Comprovante de Localização: Confirmation of the company's physical address.
4. Idoneidade Financeira: Analysis of the company's financial health.
5. Integralização de Capital: Verification of the company's capital stock integration.
6. Licença Ambiental: Evaluation of compliance with environmental regulations.
7. Limitação de Atestados: Verification of the minimum and maximum number of certificates required.

This dataset is used for training machine learning models to detect signs of fraud in public procurement processes. The multilabel structure allows the models to learn to identify multiple suspicious characteristics simultaneously, providing a valuable tool for the analysis and prevention of fraud in public contracts.

bidCorpus_object_similarity

This dataset is designed to assess text similarity in the "object" section of bidding notices by comparing pairs of distinct notices. Annotated by experts in public procurement, each entry consists of a pair of "object" sections labeled with:

• 1: The sections are similar.
• 0: The sections are not similar.

The dataset supports tasks such as document comparison, clustering, and retrieval. It provides a valuable resource for training and evaluating models on how effectively they can determine similarities between bidding notices.

The pairs are annotated with expert labels to ensure high-quality data, making this dataset ideal for developing and testing algorithms for text similarity analysis. It helps improve the efficiency and accuracy of managing and analyzing bidding documents.

bidCorpus_objects_correct_allowed

This dataset focuses on two classifications related to the "object" section of bidding notices:

1. Object Classification: Determines whether a section is the "object" section of a bidding notice.
2. Permissivity Classification: Assesses whether the object requires permissivity, meaning whether the contract involves areas such as the purchase of medications, cleaning services, or fuels, which might necessitate a certificate of location and an environmental license from regulatory institutions overseeing these activities.

The dataset provides labels for these classifications to support the analysis of compliance and requirements in bidding documents.

bidCorpus_objects_type

This dataset focuses on classifying the type of procurement found in the "object" section of bidding notices. Specifically, it categorizes the type of product or service being bid on into one of the following categories:

• Consumables: Items that are used up or consumed during use, such as office supplies or food products.
• Permanent Assets: Items with a longer lifespan that are intended for repeated use, such as machinery or equipment.
• Services: Non-tangible activities provided to fulfill a need, such as consulting or maintenance services.
• Engineering Works: Projects related to construction, infrastructure, or other engineering tasks.

The dataset provides labels for these classifications to assist in the analysis and organization of bidding documents, facilitating a better understanding of procurement types and aiding in the efficient management of bidding processes.

bidCorpus_qual_model

This dataset consists of texts from the qualification section of bidding notices and is annotated using a model trained on the original fraud detection dataset. It follows a multilabel format similar to the bidCorpus_gold dataset, with labels indicating possible signs of fraud in public procurement processes.

1. Certidão de Protesto: Verification of any protests in the company's name.
2. Certificado de Boas Práticas: Assessment of adherence to recommended practices in the sector.
3. Comprovante de Localização: Confirmation of the company's physical address.
4. Idoneidade Financeira: Analysis of the company's financial health.
5. Integralização de Capital: Verification of the company's capital stock integration.
6. Licença Ambiental: Evaluation of compliance with environmental regulations.
7. Limitação de Atestados: Verification of the minimum and maximum number of certificates required.

Unlike the expert-annotated previous dataset, this dataset has been annotated by a model trained on that data. This automated process ensures consistency and scalability while utilizing insights from the original expert annotations.

The dataset is intended for training and evaluating machine learning models to detect fraud in public procurement. The automated annotation enhances research and development in fraud detection, aiming to improve the accuracy and efficiency of identifying suspicious activities in bidding notices. Its multilabel structure supports the identification and classification of multiple fraud indicators simultaneously, aiding in the ongoing analysis and prevention of fraudulent practices in public contracts.

bidCorpus_qual_weak_sup

This dataset consists of texts from the qualification section of bidding notices and is annotated using weak supervision techniques, specifically through regular expressions. It follows a multilabel format similar to the bidCorpus_gold dataset, with labels indicating possible signs of fraud in public procurement processes.

1. Certidão de Protesto: Verification of any protests in the company's name.
2. Certificado de Boas Práticas: Assessment of adherence to recommended practices in the sector.
3. Comprovante de Localização: Confirmation of the company's physical address.
4. Idoneidade Financeira: Analysis of the company's financial health.
5. Integralização de Capital: Verification of the company's capital stock integration.
6. Licença Ambiental: Evaluation of compliance with environmental regulations.
7. Limitação de Atestados: Verification of the minimum and maximum number of certificates required.

Unlike the previous expert-annotated dataset, this dataset has been annotated using weak supervision techniques, specifically regular expressions. This approach provides a scalable method for labeling data by applying patterns to identify potential fraud indicators, although it may lack the precision of expert annotations.

The dataset is designed for training and evaluating machine learning models to detect fraud in public procurement. The use of weak supervision through regular expressions facilitates the creation of large annotated datasets, supporting research and development in fraud detection. The multilabel structure allows models to classify multiple fraud indicators simultaneously, improving the efficiency of identifying and preventing fraudulent practices in public contracts.

bidCorpus_sections_type

This dataset classifies different types of sections in bidding notices. The sections are categorized into the following labels:

• Habilitação: Qualification section, where eligibility criteria and requirements are outlined.
• Julgamento: Evaluation section, detailing the criteria and process for assessing bids.
• Objeto: Object section, specifying the item or service being procured.
• Outros: Other sections that do not fall into the categories above.
• Credenciamento: Accreditation section, where the process for validating and registering vendors is described.

The dataset provides a systematic approach to categorize the various sections found in bidding notices, facilitating better organization and analysis of procurement documents.

bid_corpus_raw

This dataset consists of raw, unlabeled texts from sections of bidding notices. The sections included are:

• Objeto: Describes the item or service being procured.
• Julgamento: Outlines the criteria and process for evaluating bids.
• Credenciamento: Details the procedures for vendor registration and validation.
• Condições de Participação: Specifies the conditions required for participation in the bidding process.
• Habilitação: Provides information on the qualifications and eligibility criteria for bidders.

This dataset offers a collection of unprocessed text from various sections of bidding notices, suitable for tasks such as text analysis, feature extraction, and the development of classification models.
