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 2021-05-25 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: keywords:mis. 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 28 item(s) in this carrel, and this carrel is 72,989 words long. Each item in your study carrel is, on average, 3,317 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 46. 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, children, mis, patients, disease, sars, syndrome, cov, inflammatory, infection, pediatric, clinical, multisystem, severe, may, associated, coronavirus, cases, respiratory, acute, study, cardiac, data, kawasaki, kd, case, pandemic, symptoms, reported, review, treatment, shock, adults, also, findings, immune, patient, laboratory, health, care, studies, evidence, age, features, risk, fever, il, response, new, dysfunction

Using the three most frequent words, the three files containing all of those words the most are COVID-19 in the Pediatric Population—Review and Current Evidence, Why COVID-19 is less frequent and severe in children: a narrative review, and Multisystem inflammatory syndrome in children: A systematic review.

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

inflammatory syndrome, multisystem inflammatory, kawasaki disease, coronavirus disease, pediatric patients, acute respiratory, case series, coronary artery, severe covid, systematic review, united states, respiratory syndrome, new york, severe acute, intensive care, temporally associated, cardiac involvement, shock syndrome, cytokine storm, clinical characteristics, syndrome coronavirus, pediatric covid, novel coronavirus, syndrome temporally, cohort study, cardiac dysfunction, inflammatory markers, respiratory distress, clinical presentation, hyperinflammatory shock, imaging findings, toxic shock, heart failure, immune response, inflammatory multisystem, like disease, intravenous immunoglobulin, doc id, clinical features, cord uid, reactive protein, multisystem syndrome, distress syndrome, pediatric population, hospitalized patients, gastrointestinal symptoms, disease control, macrophage activation, rights reserved, task force

And the three file that use all of the three most frequent phrases are Multisystem inflammatory syndrome in children: A systematic review Dermatologic manifestations of COVID-19-associated multisystem inflammatory syndrome in children, and Cardiac manifestations in SARS-CoV-2-associated multisystem inflammatory syndrome in children: a comprehensive review and proposed clinical approach.

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:

mis, sars, covid-19, child, kawasaki, patient, task, syndrome, hos, health, disease, cov-2, center, ards

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 Cardiac Involvment in SARS-CoV-2-Associated Inflammatory Syndromes 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. covid - American College of Rheumatology Clinical Guidance for Pediatric Patients with Multisystem Inflammatory Syndrome in Children (MIS‐C) Associated with SARS‐CoV‐2 and Hyperinflammation in COVID‐19. Version 1
  2. covid - Establishment of a pediatric COVID-19 biorepository: unique considerations and opportunities for studying the impact of the COVID-19 pandemic on children
  3. cov - Prior infection by seasonal coronaviruses does not prevent SARS-CoV-2 infection and associated Multisystem Inflammatory Syndrome in children

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. mis, covid, children - American College of Rheumatology Clinical Guidance for Pediatric Patients with Multisystem Inflammatory Syndrome in Children (MIS‐C) Associated with SARS‐CoV‐2 and Hyperinflammation in COVID‐19. Version 1
  2. children, sars, cov - Prior infection by seasonal coronaviruses does not prevent SARS-CoV-2 infection and associated Multisystem Inflammatory Syndrome in children
  3. covid, children, pediatric - Establishment of a pediatric COVID-19 biorepository: unique considerations and opportunities for studying the impact of the COVID-19 pandemic on children
  4. covid, patients, health - Extensions and Adaptations of Existing Medical Information System in Order to Reduce Social Contacts During COVID-19 Pandemic
  5. rash, patients, covid - Mucocutaneous Disease and Related Clinical Characteristics in Hospitalized Children and Adolescents with COVID-19 and MIS-C

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?":

children, patients, disease, syndrome, infection, cases, data, study, symptoms, coronavirus, case, treatment, shock, pandemic, adults, review, patient, findings, studies, laboratory, evidence, age, risk, features, dysfunction, fever, involvement, response, care, years, blood, cohort, inflammation, characteristics, centers, results, markers, virus, reports, system, number, series, illness, presentation, time, failure, manifestations, artery, health, population

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:

including, associated, reported, using, describing, presenting, following, suggest, requiring, provides, showed, compared, developed, based, covid-19, increased, related, hospitalized, considered, found, observed, needed, treat, confirmed, affected, identified, known, collected, characterized, seen, performed, infected, regarding, recommended, given, remains, met, reduced, published, leading, makes, emerged, elevated, appeared, demonstrating, obtained, test, involved, understand, suspected

Proper Nouns

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

MIS, C, COVID-19, SARS, CoV-2, Kawasaki, KD, Multisystem, Syndrome, Children, Inflammatory, Disease, C., IVIG, Coronavirus, China, PCR, Health, Pediatric, New, States, IL-6, York, United, S, CDC, ARDS, Fig, CRP, Table, J, US, Wuhan, RT, mg, Clinical, May, Control, April, anakinra, ICU, CT, TSS, Italy, June, Task, Prevention, sha, UK, MRI

An analysis of personal pronouns enables you to answer at least two questions: 1) "What, if any, is the overall gender of my study carrel?", and 2) "To what degree are the texts in my study carrel self-centered versus inclusive?"

we, it, our, their, they, its, he, she, i, them, his, her, your, us, my, itself, you, one, -all, s, ours, him, em

Below are words cloud of your study carrel's proper & personal pronouns.

Adjectives & Verbs

Learning about a corpus's adjectives and adverbs helps you answer how questions: "How are things described and how are things done?" An analysis of adjectives and adverbs also points to a corpus's overall sentiment. "In general, is my study carrel positive or negative?"

inflammatory, severe, clinical, pediatric, respiratory, acute, covid-19, multisystem, cardiac, immune, high, positive, viral, coronary, higher, like, similar, common, novel, initial, elevated, present, possible, lower, systematic, infectious, many, low, mild, new, recent, several, myocardial, early, ventricular, medical, paediatric, systemic, significant, gastrointestinal, likely, available, specific, pulmonary, normal, important, first, asymptomatic, observational, negative
