Introduction

This is a Distant Reader "study carrel", a set of structured data intended to help the student, researcher, or scholar use & understand a corpus.

This study carrel was created on 2021-05-30 by Eric Morgan <emorgan@nd.edu>. The carrel was created using the Distant Reader cord process, and the input was the result of a query applied to a local mirror of CORD, a data set of scholarly articles on the topic of COVID-19. The actual query was: facet_journal:"Travel Med Infect Dis". The results of this query were saved in a cache and transformed into a set of plain text files. All of the analysis -- "reading" -- has been done against these plain text files. For example, a short narrative report has been created. This Web page is a more verbose version of that report.

All study carrels are self-contained -- no Internet connection is necessary to use them. Download this carrel for offline reading. The carrel is made up of many subdirectories and data files. The manifest describes each one in greater detail.

Size

There are 63 item(s) in this carrel, and this carrel is 62,714 words long. Each item in your study carrel is, on average, 2,613 words long. If you dig deeper, then you might want to save yourself some time by reading a shorter item. On the other hand, if your desire is for more detail, then you might consider reading a longer item. The following charts illustrate the overall size of the carrel.

Readability

On a scale from 0 to 100, where 0 is very difficult and 100 is very easy, the documents have an average readability score of 51. Consequently, if you want to read something more simplistic, then consider a document with a higher score. If you want something more specialized, then consider something with a lower score. The following charts illustrate the overall readability of the carrel.

Word Frequencies

By merely counting & tabulating the frequency of individual words or phrases, you can begin to get an understanding of the carrel's "aboutness". Excluding "stop words", some of the more frequent words include:

covid, cov, patients, sars, cases, respiratory, hajj, coronavirus, disease, health, study, infection, influenza, virus, pilgrims, mers, clinical, among, travel, also, reported, outbreak, may, transmission, risk, symptoms, data, infectious, infections, pandemic, control, novel, time, severe, countries, tb, syndrome, mass, case, human, public, one, hospital, diseases, number, days, high, china, people, world

Using the three most frequent words, the three files containing all of those words the most are SARS-CoV-2 jumping the species barrier: zoonotic lessons from SARS, MERS and recent advances to combat this pandemic virus, Risk of Hospitalization for Covid-19 Outpatients Treated with Various Drug Regimens in Brazil: Comparative Analysis, and Epidemiological and clinical characteristics of the first 557 successive patients with COVID-19 in Pernambuco state, Northeast Brazil.

The most frequent two-word phrases (bigrams) include:

respiratory syndrome, novel coronavirus, public health, acute respiratory, syndrome coronavirus, saudi arabia, middle east, east respiratory, mass gatherings, hajj pilgrims, infectious disease, infectious diseases, severe acute, coronavirus disease, infect dis, mass gathering, cord uid, travel med, doc id, dis doi, med infect, healthcare workers, respiratory tract, travel medicine, respiratory infections, world health, health organization, united states, health care, sore throat, infection control, asymptomatic cases, respiratory symptoms, influenza virus, clinical trials, pandemic influenza, clinical symptoms, cov infection, respiratory viruses, among pilgrims, confirmed cases, ebola virus, coronavirus infection, clinical characteristics, virus infection, risk factors, tract infections, control measures, human transmission, general population

And the three file that use all of the three most frequent phrases are SARS-CoV-2 jumping the species barrier: zoonotic lessons from SARS, MERS and recent advances to combat this pandemic virus Influenza is more common than Middle East Respiratory Syndrome Coronavirus (MERS-CoV) among hospitalized adult Saudi patients, and Predictors of MERS-CoV infection: A large case control study of patients presenting with ILI at a MERS-CoV referral hospital in Saudi Arabia.

While often deemed superficial or sophomoric, rudimentary frequencies and their associated "word clouds" can be quite insightful:

Keywords

Sets of keywords -- statistically significant words -- can be enumerated by comparing the relative frequency of words with the number of times the words appear in an entire corpus. Some of the most statistically significant keywords in the carrel include:

covid-19, sars, hajj, mers, hcq, china, umrah, respiratory, pilgrim, patient, libya, iran, hiv, ebola, east, disease, zikv, world, virus, vietnam, unhcr, u.s., traveler, travel, temperature, study, spring, social, singapore, sierra, religious, refugee, point, period, participant, outbreak, mass, march, mandarin, ksa, kong, jean, japanese, influenza, infectious, ili, human, hong, health, h1n1

And now word clouds really begin to shine:

Topic Modeling

Topic modeling is another popular approach to connoting the aboutness of a corpus. If the study carrel could be summed up in a single word, then that word might be covid, and The kidney and COVID-19 patients – important considerations is most about that word.

If the study carrel could be summed up in three words ("topics") then those words and their significantly associated titles include:

  1. cov - SARS-CoV-2 jumping the species barrier: zoonotic lessons from SARS, MERS and recent advances to combat this pandemic virus
  2. cases - From the “Madding Crowd” to mass gatherings-religion, sport, culture and public health
  3. covid - Risk of Hospitalization for Covid-19 Outpatients Treated with Various Drug Regimens in Brazil: Comparative Analysis

If the study carrel could be summed up in five topics, and each topic were each denoted with three words, then those topics and their most significantly associated files would be:

  1. sars, cov, covid - SARS-CoV-2 jumping the species barrier: zoonotic lessons from SARS, MERS and recent advances to combat this pandemic virus
  2. cases, disease, health - From the “Madding Crowd” to mass gatherings-religion, sport, culture and public health
  3. hajj, pilgrims, respiratory - Clinical respiratory infections and pneumonia during the Hajj pilgrimage: A systematic review
  4. covid, patients, risk - Risk of Hospitalization for Covid-19 Outpatients Treated with Various Drug Regimens in Brazil: Comparative Analysis
  5. virus, covid, patients - Therapeutic use of chloroquine and hydroxychloroquine in COVID-19 and other viral infections: A narrative review

Noun & Verbs

Through an analysis of your study carrel's parts-of-speech, you are able to answer question beyonds aboutness. For example, a list of the most frequent nouns helps you answer what questions; "What is discussed in this collection?":

patients, cases, study, disease, infection, influenza, pilgrims, coronavirus, virus, health, outbreak, risk, symptoms, data, transmission, infections, time, countries, pandemic, case, number, days, people, control, treatment, diseases, studies, travel, rate, epidemic, population, travelers, hospital, care, fever, years, gatherings, syndrome, information, results, model, cough, use, patient, measures, age, pneumonia, authors, viruses, healthcare

An enumeration of the verbs helps you learn what actions take place in a text or what the things in the text do. Very frequently, the most common lemmatized verbs are "be", "have", and "do"; the more interesting verbs usually occur further down the list of frequencies:

reported, included, used, showed, infect, based, associated, found, confirmed, increased, provides, travel, returning, testing, followed, occur, presenting, emerging, considered, developed, take, identified, caused, spreading, imported, reduce, required, related, gave, defined, treating, known, hospitalized, affects, leading, suspected, controlled, performed, suggested, need, make, compare, recommended, remains, received, detect, acquired, indicate, admitted, become

Proper Nouns

An extraction of proper nouns helps you determine the names of people and places in your study carrel.

SARS, Hajj, COVID-19, MERS, CoV-2, CoV, TB, China, Coronavirus, Health, Saudi, East, Middle, Arabia, H1N1, Wuhan, Fig, HCQ, World, remdesivir, March, Disease, Med, U.S., CQ, Syndrome, Respiratory, Iran, sha, Organization, Umrah, Ebola, April, A, YouTube, KSA, Infectious, Brazil, Table, United, ILI, States, Influenza, America, ACE2, RNA, PCR, Medicine, CoVs, Africa
