Why this Mini-project?

A viral epidemic poses a threat to human life and the last resort to tackle it, on which the entire human race rely on, is the availablity of drugs. With varieities of drugs available to us, for example anti-viral drugs, palliative drugs, antibacterial drugs and so on, it has become difficult to track the role of the drug. While some drugs are proving to be effective antiviral there are drugs that only cure the symptoms. Hence, this miniproject provides the necessary tools that would provide complete information at one one place to the public.

Objectives :

• To create a dictionary consisting of drugs for viral diseases and its local name in different countries.
• Differentiate drugs that work directly against the virus and the drugs that only work on symptoms.

Tools :

• getpapers to obtain research papers. To know more about getpapers click here.
• ami for sectioning paper. To know more about sectioning via ami click here.
• ami/SPARQL for the creation of dictionaries. Click to know about dictionary creation via ami and sparql.
• nodejs, nvm, cmd, maven, jdk, git are backbone of the above mentioned tools without which commands cannot be executed.
• Python, R and related software for used data analysis.

Corpus950

This comprises of top 950 articles retrieved from EuroPMC which is a platform that provides free acces to million of articles related to biomedical science. getpapers will be used to search and download these articles. The processing of the software is very quick (approx 10 minutes) which which when downloaded individually could have taken 'n' number of hours. In this project such articles will be downloaded to study drugs related to viral epidemics.

The other advantage of this project is we dont have to go through all the papers to understand the gist instead with the help of ami : section the papers are tabulated/sectioned and one can go through all without reading them all and select the ones that is of interest.

Course of Action :

For this purpose, the following command will be executed :

getpapers -q "viral epidemics and drugs" -o dir_corpus950 -x -p -k 1000

The command getpapers will initiate the process and -q refers to the query which is to be searched. The query is entered in inverted commas as is done in "viral epidemics and drugs". The next element is -o which refers to output directory and the parameter that follows it in the name of the directory which is dir_corpus950 in our case. Then, -x -p corresponds to xml and pdf files to be included in our search and -k 1000 limits our search to 1,000 files only. After successful completion of the command we get our Corpus-950 ready.

Sectioning of downloaded files will create a tree structure for us which will help in exploring the content of the file. Sectioning done using section function of ami. The command executed will be : ami -p dir_corpus950 section

Drugs Dictionary

Wikidata is an open-source database containing information stored semantically. Thus, applications of softwares could help us relate various properties of similar drugs and use it constructively. So, we will be creating a dictionary with an attempt to simplify the downloaded 950 articles and relate drugs with its usage. This would require application of 'machine learning' to achieve the same.

Course of Action :

When all the files are downloaded and succesfully stored in our dir_corpus950 directory, our next task is to generate the dictionary using ami tools. We will use the follwing command:

ami -p dir_corpus950 search --dictionary drugs

ami will initiate the ami function and -p will set the path to dir_corpus950. Then search --dictionary drugs will search drugs from the dictionary and create an html file consisting of the data in a tabular form.

Goals

1. To differentiate false positive and true positive, i.e to find papers that are related to "viral epidemic and drugs" and remove unnecessary ones.
2. To find relationship between drugs, this may help in suggesting alternative drug for an epidemic.
3. To segregate drugs that take action against the virus and the drugs that suppresses only the symptoms.
4. To maintain a simplified drug dictionary that would be open to public.

Miniproject Summary

Objective :

• The goal is to find out "the drugs which are used to treat viral diseases and their local name in different countries "
• Insight many drugs has been reported that they are used to "treat only the symptoms caused by viral infection or diseases than viral infection". In an account of it studying the purpose of drugs and their drugs action.

Methodology :

1. Creating dictionaries
2. Binary classification
3. Sectioning
4. Finding local drugs in countries
5. Drug action

Corpora :

1. A communal corpus called epidemic50noCov of 50 articles for viral epidemics is created.
2. Expanding our search we create a new corpus consisting of 950 papers.
3. Using software tools we create a dictionary for our corpus.

Dictionaries :

1. A test drug dictionary was created using a list of 10 viral drugs.
2. List of FDA approved drugs has been updated. (Refer Here)

Softwares :

• ami for dictionaries and sectioning.
• ami/SPARQL for the creation of dictionaries.
• Python, Rrelated software for data analysis.

Commiting Corpus :

To commit corpus via git we use the following commands :

C:\Users\admin\openVirus\miniproject\drug>git status

C:\Users\admin\openVirus\miniproject\drug>dir

C:\Users\admin\openVirus\miniproject\drug>git add *

C:\Users\admin\openVirus\miniproject\drug>git status

C:\Users\admin\openVirus\miniproject\drug>git commit -am "first commit all corpus"

C:\Users\admin\openVirus\miniproject\drug>git pull

C:\Users\admin\openVirus\miniproject\drug>git push

This will initiate redirection of the page to login to your GitHub account. Successful execution of the mentioned commands will commit the files.

Constraints :

The pharmaceutical drugs are listed here with their INN (International Non-proprietary Name) name instead of biological/natural name.
