    Abstract Today according to social media, the internet, Etc. Data is rapidly produced and occupies a large space in systems that have resulted in enormous data warehouses; the progress in information technology has significantly increased the speed and ease of data flow.text mining is one of the most important methods for extracting a useful model through extracting and adapting knowledge from data sets. However, many studies have been conducted based on the usage of deep learning for text processing and text mining issues.The idea and method of text mining are one of the fields that seek to extract useful information from unstructured textual data that is used very today. Deep learning and machine learning techniques in classification and text mining and their type are discussed in this paper as well. Neural networks of various kinds, namely, ANN, RNN, CNN, and LSTM, are the subject of study to select the best technique. In this study, we conducted a Systematic Literature Review to extract and associate the algorithms and features that have been used in this area. Based on our search criteria, we retrieved 130 relevant studies from electronic databases between 1997 and 2021; we have selected 43 studies for further analysis using inclusion and exclusion criteria in Section 3.2. According to this study, hybrid LSTM is the most widely used deep learning algorithm in these studies, and SVM in machine learning method high accuracy in result shown.

    Abstract Background & objectives: Lung involvement is crucial in patients with Covid-19. The CT scan plays a key role in diagnosing of this disease. This study aimed to survey CT scan involvement patterns in patients with suspected Covid-19 symptoms. Methods: The present study was cross-sectional,analytical in which the statistical population was patients with typical clinical symptoms of Covid-19 who were referred to the hospital imaging center from March 2019 to May 2019. A total of 301 patients were randomly selected as a sample. Data analysis was performed using SPSS version 26 at a significance level of 0.05. Results: The average age of the participants in the study was 54.6±17.6. 151 patients (50.2%) were male. 255 patients (84.7%) were treated on an outpatient basis, 37 patients (12.3%) were treated in the Non ICU ward and nine patients (3%) were treated in the intensive care unit(ICU). One hundred sixty eight patients (55.8%) with grand glass conflict, 25 patients (8.3%) with consolidation conflict, 49 patients (16.3%) with linear turbidity were identified while 44 patients (14.6%) had crazy paving, 7 patients (2.3%) had small nodules and 45 patients (15%) had round opacities on contrast-free CT scan. The pattern of conflict in the form of linear turbidity was directly and significantly related to the severity of the disease. Conclusion: Imaging findings in patients with Covid-19 have a wide range. Despite these findings, attention should be paid to less common and rare signs and symptoms that can help make the right decision and more definitive diagnosis of the disease.

    Abstract Internet forums and public social media, such as online healthcare forums, provide a convenient channel for users (people/patients) concerned about health issues to discuss and share information with each other. In late December 2019, an outbreak of a novel coronavirus (infection from which results in the disease named COVID-19) was reported, and, due to the rapid spread of the virus in other parts of the world, the World Health Organization declared a state of emergency. In this paper, we used automated extraction of COVID-19-related discussions from social media and a natural language process (NLP) method based on topic modeling to uncover various issues related to COVID-19 from public opinions. Moreover, we also investigate how to use LSTM recurrent neural network for sentiment classification of COVID-19 comments. Our findings shed light on the importance of using public opinions and suitable computational techniques to understand issues surrounding COVID-19 and to guide related decision-making. In addition, experiments demonstrated that the research model achieved an accuracy of 81.15% - a higher accuracy than that of several other well-known machine-learning algorithms for COVID-19-Sentiment Classification.

    Abstract Medical data in online groups and social media contain valuable information, which is provided by both healthcare professionals and patients. In fact, patients can talk freely and share their personal experiences. These resources are a valuable opportunity for health professionals who can access patients' opinions, as well as discussions between patients. Recently, the data processing of the health community and, how to extract knowledge is a significant technical challenge. There are many online group and forums that users can discuss on healthcare issues. Therefore, we can examine these text documents for discovering knowledge and evaluating patients' behavior based on their opinions and discussions. For example, there are many questions and answering groups on Twitter or Facebook. Given the importance of the research, in this paper, we present a semantic framework based on topic model (LDA) and Random forest(RF) to predict and retrieval latent topics of healthcare text-documents from an online forum. We extract our healthcare records (patient-questions) from patient.info website as a real dataset. Experiments on our dataset show that social media forums could help for detecting significant patient safety problems on healthcare issues.
