RESUMO
Several studies applying Machine Learning to deception detection have been published in the last decade. A rich and complex set of settings, approaches, theories, and results is now available. Therefore, one may find it difficult to identify trends, successful paths, gaps, and opportunities for contribution. The present literature review aims to provide the state of research regarding deception detection with Machine Learning. We followed the PRISMA protocol and retrieved 648 articles from ACM Digital Library, IEEE Xplore, Scopus, and Web of Science. 540 of them were screened (108 were duplicates). A final corpus of 81 documents has been summarized as mind maps. Metadata was extracted and has been encoded as Python dictionaries to support a statistical analysis scripted in Python programming language, and available as a collection of Jupyter Lab Notebooks in a GitHub repository. All are available as Jupyter Lab Notebooks. Neural Networks, Support Vector Machines, Random Forest, Decision Tree and K-nearest Neighbor are the five most explored techniques. The studies report a detection performance ranging from 51% to 100%, with 19 works reaching accuracy rate above 0.9. Monomodal, Bimodal, and Multimodal approaches were exploited and achieved various accuracy levels for detection. Bimodal and Multimodal approaches have become a trend over Monomodal ones, although there are high-performance examples of the latter. Studies that exploit language and linguistic features, 75% are dedicated to English. The findings include observations of the following: language and culture, emotional features, psychological traits, cognitive load, facial cues, complexity, performance, and Machine Learning topics. We also present a dataset benchmark. Main conclusions are that labeled datasets from real-life data are scarce. Also, there is still room for new approaches for deception detection with Machine Learning, especially if focused on languages and cultures other than English-based. Further research would greatly contribute by providing new labeled and multimodal datasets for deception detection, both for English and other languages.

A internet das coisas e o aprendizado de máquina são temas emergentes na área da saúde com potencial para otimizar a área e criar um sistema de saúde inteligente em virtude do envelhecimento da população. Este artigo analisa a produção científica do período de 2009 a 2019 a respeito da internet das coisas e do aprendizado de máquina na área da saúde. Utiliza metodologia bibliométrica em 1.353 artigos recuperados na base de dados Web of Science. Constata um crescimento da produção científica sobre o tema, sendo os Estados Unidos o principal polo de pesquisa na área. Identifica os autores mais produtivos e com maior impacto, periódicos mais produtivos, colaboração entre países e palavras-chave utilizadas, bem como suas relações. Incentiva que novas pesquisas explorem as abordagens identificadas no estudo.
