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 2021-05-24 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:europe. 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 56 item(s) in this carrel, and this carrel is 420,166 words long. Each item in your study carrel is, on average, 16,806 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:

health, virus, disease, europe, also, patients, countries, will, imaging, may, european, new, infection, cases, clinical, risk, public, diseases, high, treatment, first, viruses, infections, human, well, different, one, influenza, used, fever, many, data, study, use, however, two, among, isolated, associated, time, world, population, role, analysis, based, strains, years, research, important, ct

Using the three most frequent words, the three files containing all of those words the most are Single-Stranded RNA Viruses, Expanding the Concept of Public Health, and Viral zoonoses in Europe.

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

public health, infectious diseases, health care, european countries, climate change, hemorrhagic fever, world war, raccoon dogs, united states, raccoon dog, job satisfaction, working conditions, west nile, avian influenza, influenza virus, borne encephalitis, risk factors, per cent, fever virus, learning objectives, health promotion, infectious disease, congo hemorrhagic, developing countries, nile virus, encephalitis virus, spotted fever, natural foci, th century, acute respiratory, differential diagnosis, closely related, european union, respiratory syndrome, may also, north america, virus infection, across europe, middle east, risk perception, communicable diseases, important role, imaging techniques, doc id, yersinia pestis, pandemic influenza, cord uid, imaging modalities, northern eurasia, economic growth

And the three file that use all of the three most frequent phrases are Expanding the Concept of Public Health The role of law in pandemic influenza preparedness in Europe, and Building the Infrastructure and Regulations Needed for Public Health and Fitness.

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:

europe, disease, european, africa, sars, health, covid-19, country, usa, infection, asia, virus, spain, public, patient, hiv, united, tick, study, russia, pcr, objective, migration, mediterranean, isolate, fever, east, dna, crimean, congo, clinical, case, airport, yersinia, world, wnv, wild, west, water, war, ussr, tumour, treatment, trade, tobacco, tja, tgev, technique, tbev, table

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 health, and A fragile and divided European Union meets Covid-19: further disintegration or ‘Hamiltonian moment’? 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. virus - Single-Stranded RNA Viruses
2. health - Expanding the Concept of Public Health
3. imaging - ECR 2014, Part A

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. virus, infection, patients - Single-Stranded RNA Viruses
2. health, public, disease - Expanding the Concept of Public Health
3. imaging, will, ct - ECR 2014, Part A
4. countries, europe, european - Chapter 15 A Global Approach to Energy and the Environment The G-Cubed Model
5. ancient, disease, pestis - Ancient pathogen genomics as an emerging tool for infectious disease research

Moreover, the totality of the study carrel's aboutness, can be visualized with the following pie chart:

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?":

health, virus, disease, patients, countries, imaging, infection, cases, risk, diseases, treatment, infections, viruses, data, fever, time, role, study, population, years, analysis, influenza, strains, case, use, species, care, conditions, results, number, studies, research, factors, diagnosis, group, resistance, transmission, people, pandemic, country, development, rate, outbreak, patient, level, world, systems, management, methods, control

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:

use, including, show, increasing, isolated, provided, find, based, associate, developed, caused, followed, became, reports, occur, makes, related, reduce, take, saw, require, detected, led, considered, borne, affecting, identified, emerging, suggests, improve, compared, needed, performing, known, giving, allow, describes, presented, discuss, remained, involves, understood, learned, established, indicating, resulted, determining, infected, according, spreading

Proper Nouns

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

Europe, CT, SARS, US, EU, MRI, Africa, European, Asia, Health, World, PCR, China, Italy, Russia, USA, Germany, Spain, MR, United, France, War, East, UK, America, HIV, COVID-19, West, New, Roma, States, CoV-2, International, Finland, North, Mediterranean, Influenza, C., Union, South, A, Rickettsia, Nile, MRSA, S., Republic, Table, Fig, RNA, M

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?"

it, their, we, its, they, our, them, i, his, he, itself, us, one, you, themselves, her, your, my, she, him, ourselves, himself, me, 's, oneself, yourself, thy, theirs, o139, mg, hr)ct, herself, em, arda

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?"

clinical, new, high, european, public, different, many, human, first, important, common, specific, infectious, non, social, small, higher, large, economic, several, global, international, possible, severe, medical, low, early, major, acute, significant, diagnostic, environmental, recent, positive, available, main, primary, natural, genetic, current, respiratory, national, viral, effective, key, long, local, lower, similar, potential

also, well, however, often, even, especially, still, therefore, now, highly, usually, recently, mainly, significantly, respectively, particularly, less, first, currently, widely, later, far, frequently, increasingly, previously, relatively, furthermore, encephalitis, much, already, almost, rather, finally, together, generally, closely, potentially, directly, rapidly, worldwide, commonly, indeed, probably, just, always, nt, mostly, yet, primarily, long
