Professional fact-checking tends to be costly and scalability challenges. For this reason, a series of methods to automate this process has been emerging. However, these methods have been created with monolithic architectures, not making use of pre-built parts, and are harder to be understood by others. This work aims to propose a framework, where the development of methods can be done in a modular manner, creating workflows based on key steps that can be linked together to generate the input classification. The framework makes use of a proposed data traceability ontology to map all generated data during execution under a unified vocabulary, which facilitates communication between these independent components.

ReVera Framework: Um Framwork para rastreabilidade em fact-checking automático

The advance on Question Answering systems has achieved significant results, and new related problems have arisen. Few studies have addressed the Complex Knowledge Base Question Answering (C-KBQA) problem. This work presents an overview of C-KBQA systems. A collection of 54 papers were systematically selected, and a map of the methods, approaches, trends, future directions, and gaps in the C-KBQA research was performed. This study shows that C-KBQA systems need to handle multi-hop and constraint questions, and two approaches are usually used to address this problem.

Uma revisão breve sobre perguntas complexas em bases de conhecimento para sistemas de perguntas e respostas

The search for information is inherent to the human being and with the popularization of computers, search systems have become the main source of obtaining knowledge. However, they do not support greater user interaction when they want to do a complex search. It is important to evaluate the user and infer information about him, to know his intention to search to increase the performance of these systems under the principles of SaL. In this paper, we propose a model for classifying the search intention using Transformers. It was used an available dataset and we obtained 97% accuracy in the validation set and 99% f-measure in the test set, achieving better results when comparing to traditional methods.

Predicting the User Intention in Web Search

Professional fact-checking tends to be costly and scalability challenging. For this reason, a series of methods to automate this process has been emerging. Unfortunately, these methods have been created with monolithic architectures, not making use of pre-built parts, and are harder to be understood by others. This work aims to propose a framework, where the development of methods can be done in a modular manner, creating workflows based on key steps that can be linked together to generate the input classification. For this, a study of the literature was conducted to identify the main processing steps of the methods, seeking to develop a solution that would guarantee flexibility of execution and interoperability between the different processing components. With this, the automatic verification process was described in a limited set of steps that can be performed, creating independent components that implement each of them. The framework makes use of a proposed data traceability ontology to map all generated data during execution under a unified vocabulary, which facilitates communication between these independent components.

O RECMEM é um hub de conteúdos educacionais que anota e indexa conteúdos de repositórios educacionais (inclusive repositórios privados) e LMS (Learning Management System), como o Moodle e que, através de sistemas de recomendação, auxilia o professor na preparação de materiais de apoio ao ensino remoto e na recomendação de conteúdos aos seus alunos, além de compilar dados de escolas e permitir aos gestores de ensino uma análise ampliada e comparativa sobre as instituições. Atualmente o RECMEM se destaca por ser o maior repositório de material educacional do país com materiais para professores e alunos do ensino fundamental e médio, podendo também ser utilizado para indexar materiais de domínios específicos e de outros níveis.
