On January 9, 2020, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), formerly known as 2019-nCoV,was declared the causative agent in 15 of the 59 hospitalized patients in Wuhan, Hubei Province, causing great concern: this new coronavirus has 70% genetic association with SARS and is a subspecies of Sarbecovirus. The virus is temporarily named the 2019-nCoV virus[1] and the Coronavirus Study Group has nominated the virus as SARS-CoV-2[2].

In January 2020, more positive cases from other countries such as Thailand, Japan, South Korea, and the United States of America were reported by January 20, 2020, and the transmission of individual-to-health care, further complicated the situation[3].

Coronaviruses are zoonotic, meaning they are transmitted between animals and people, but the ways in which it is transmitted, animal reservoirs, prophylaxis, and precise clinical manifestations requires more investigation. There is currently no vaccine and appropriate treatment for COVID-19, so a high index of clinical suspicion and inquiring about the history of travel and contact from patients with fever and respiratory symptoms play a critical role in the prevention and control of the disease[4].

On a daily basis, a large number of Websites and online social media produce a large amount of data in a variety of fields such as technology, medicine, history, political and social news, arts and other fields. Analyzing and classifying these data leads to the production of knowledge and nowadays, it has attracted the attention of many researchers[5].

Web news mining is one of the most signi ficant tools and the subset sciences “Big Data” in social networking. A web news miningbased automatic system can monitor, evaluate, and categorize news,which, in addition to managing news articles, it is also applied in the field of advisory systems[6].

Social networks fall into six groups as follows[7]: 1. Microblogging platforms: such as twitter; 2. Blogging platforms: such as WordPress and Blogger; 3. Instant messaging Apps: such as WhatsApp and Telegram; 4. Networking platforms: such as Facebook and LinkedIn; 5. Software elaboration platform: such as GitHub; 6. Photo/video sharing platforms: such as Instagram and YouTube.

The Twitter social networking is a micro-blogging platform considered by researchers as a result of useful applications. There are over 320 million active subscribers on the social network, which daily generates approximately 6 million tweets containing instant news and comments; due to the wealth of information and their easy access. Twitter has extensive applications, such as the predicting a political process, investigating the effectivity of a product,monitoring the events pertaining to the health and hygiene[8].Approximately 23% of Twitter subscribers are adults and on a daily basis, a total of approximately 500 million Tweets are broadcasted each day[9].

In the model presented in this study, unstructured data on a novel coronavirus (2019-nCoV) are extracted from Twitter and then subjected to text cleaning, so-called screening or filtering, and finally classification operations. Since the focus is on real-time programming, this model is implemented using a fuzzy rule-based evolutionary algorithm called Eclass1-MIMO.

One of the most effective ways to prevent and control epidemics is to monitor and track the news and social networks about the spread of infectious diseases. In this study, the FAMEC method was used to send an alert message to surveillance systems for timely detection outbreaks of the COVID-19.

The FAMEC method has four main phases as follows:

1. Clearing and integrating data and extracting vocabulary; 2. Web and tweet crawling; 3. Applying fuzzy rules and storing data using fuzzy classi fier. 4. Visualizing and sending messages.

The visualization component of the suggested method aims to assist in real-time monitoring and tracking of the beginning and spread of outbreaks, which can greatly contribute to the effectiveness of public health surveillance systems in this area.

Initially, during the period between Dec. 312019 and Feb. 62020,2019-nCoV (COVID-19) tweets were extracted from the Twitter social network and stored in the relevant database. The collected database contained 364080 tweets from 179534 users. 21805371 users who have re-tweet or like these posts and 52837975554 times these posts have been viewed by users. The main hashtags about novel coronavirus were #corona, #ncov, #wuhan, #china, #2019-nCoV, #virus, #corona virus china, #coronavirus outbreak, wuhan virus.

Figure 1 shows the results obtained from the monitoring of a novel coronavirus (2019-nCoV) related news in the study period, which are associated to 364080 tweets from 179534 users. The most Tweets about the coronavirus have been from the US (42.1%), China(13.0%), Italy (11.8%) and Australia (6.6%). This is consistent with the report of the cases which was obtained from the WHO[10]. In this study, a new method based on fuzzy algorithm was applied for evolving of the TSK of mining, monitoring, storage and visualization of news and tweets about preparing our COVID-19. To execute the method, more than 364080 clean and integrated tweets and news were then categorized using the Eclass1-MIMO method and finally viewed in real time on the world map.

In the recent years, a signi ficant number of researchers have been working on categorizing, clustering, analyzing emotions, thinking and developing recommenders based on social data, but most of these works have focused on either news websites or Twitter.

The evolving fuzzy algorithm with the Eclass1-MIMO method was used in the study of Iglesias for classifying six areas of knowledge,health, technology, sports, arts and commerce[5]. Also, Jahanbinet al.used web news mining in infectious disease surveillance systems to timely diagnose epidemics[8].

The geographical origins of tweets posted about COVID-19 were found to be consistent with the formal WHO report about incidence cases of COVID-19 during the study period. This reflects the efficacy of the suggested method to monitor and track this infection.The limitation of the proposed method is that it cannot be used to monitor and track infectious diseases in regions with poor or no access to social networks such as Twitter and Facebook. Also, as the language of processing the tweets in this study was English, the results may be affected by the processing language.

In conclusion, due to the revolutionary development of the social networks, using the web news mining of these network used by each community, the geographical and demographical of the users can be identi fied accurately. This is due to the fact that these network report easily statistical data with the most comments, photos, videos,etc.on COVID-19. This helps to predict morbidity rates in each region,and bring attention of policy-maker in the health care systems to purposefully implement educational programs in the regions where exposed to higher risks. Finally, this can help to reduce the incidence case and even mortality in communities.
