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:"mBio". 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 62 item(s) in this carrel, and this carrel is 306,988 words long. Each item in your study carrel is, on average, 5,032 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 47. 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:

virus, cells, cov, infection, sars, rna, protein, viruses, viral, cell, using, human, influenza, infected, mice, expression, nsp, also, mers, analysis, cd, respiratory, data, host, gene, coronavirus, genes, gp, proteins, used, may, replication, response, genome, disease, small, i, specific, type, two, observed, levels, samples, binding, activity, receptor, associated, immune, study, one

Using the three most frequent words, the three files containing all of those words the most are Origins and Evolution of the Global RNA Virome, Proofreading-Deficient Coronaviruses Adapt for Increased Fitness over Long-Term Passage without Reversion of Exoribonuclease-Inactivating Mutations, and Enhanced Replication of Mouse Adenovirus Type 1 following Virus-Induced Degradation of Protein Kinase R (PKR).

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

influenza virus, respiratory syndrome, supplemental material, acute respiratory, severe acute, virus infection, syndrome coronavirus, small rnas, rna viruses, infected cells, immune response, viral rna, middle east, gene expression, small rna, east respiratory, influenza viruses, rna virus, amino acid, escherichia coli, avian influenza, vero cells, immune responses, public health, cov ma, cord uid, previously described, mbio doi, doc id, cov infection, virus replication, ebola virus, viral replication, highly pathogenic, cell surface, cell responses, viral infection, data set, cell culture, mediated ifn, ebov gp, infected mice, dsrna viruses, parainfluenza virus, innate immune, stranded rna, respiratory disease, performed using, virus titers, cov nsp

And the three file that use all of the three most frequent phrases are Single-Dose, Intranasal Immunization with Recombinant Parainfluenza Virus 5 Expressing Middle East Respiratory Syndrome Coronavirus (MERS-CoV) Spike Protein Protects Mice from Fatal MERS-CoV Infection Heterosubtypic Protections against Human-Infecting Avian Influenza Viruses Correlate to Biased Cross-T-Cell Responses, and Influenza Virus A/Anhui/1/2013 (H7N9) Replicates Efficiently in the Upper and Lower Respiratory Tracts of Cynomolgus Macaques.

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:

sars, rna, virus, mers, h5n1, h7n9, gof, covid-19, cov-2, small, sinv, pcr, function, fouchier, emc, cell, Ϫrna, Ϫ/Ϫ, wk-521, viroporin, viral, varroa, vaccine, unc, trsv, tiger, st209, spr, smq, sjr, sirp, sfb, serpine1, sequence, saa, rbd, predict, ppp, pkr, piv5-mers, piv5, pfu, pedv, pdf-2180, pc22a, pbs, pause, patience, p250, orf3-rfp

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 virus, and Comprehensive Functional Analysis of N-Linked Glycans on Ebola Virus GP1 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. cells - Origins and Evolution of the Global RNA Virome
  2. cells - Enhanced Replication of Mouse Adenovirus Type 1 following Virus-Induced Degradation of Protein Kinase R (PKR)
  3. virus - Genomic Dissection of an Icelandic Epidemic of Respiratory Disease in Horses and Associated Zoonotic Cases

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. cells, virus, rna - Origins and Evolution of the Global RNA Virome
  2. cells, virus, pkr - Viral Entry Properties Required for Fitness in Humans Are Lost through Rapid Genomic Change during Viral Isolation
  3. cov, sars, virus - Mechanisms of Severe Acute Respiratory Syndrome Coronavirus-Induced Acute Lung Injury
  4. virus, viruses, influenza - Genomic Dissection of an Icelandic Epidemic of Respiratory Disease in Horses and Associated Zoonotic Cases
  5. cells, virus, infection - Lectin-Glycan Interaction Network-Based Identification of Host Receptors of Microbial Pathogenic Adhesins

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?":

virus, cells, infection, viruses, protein, cell, expression, influenza, mice, analysis, data, host, genes, gene, proteins, coronavirus, replication, genome, response, disease, samples, activity, levels, time, type, study, membrane, receptor, results, lung, sequence, studies, syndrome, transmission, sequences, °, research, antibody, responses, culture, vaccine, number, infections, rnas, assay, patients, mouse, material, activation, model

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:

using, showed, infect, including, increased, suggest, binding, indicate, induced, expressed, associated, identified, detected, see, follow, providing, performed, observing, containing, determine, describing, find, based, mediated, compared, generate, requires, reduced, known, treated, result, inhibit, report, demonstrated, occur, predicted, confirmed, causing, analyzing, collected, testing, represent, derived, regulate, obtained, encodes, revealed, remained, targeted, isolated

Proper Nouns

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

Fig, SARS, RNA, CoV, CoV-2, MERS, M, PKR, T, PCR, H5N1, C, CD47, IFN-, GP, HCoV, S, EMC, hpi, PBS, NSP4, MHV, HN, H7N9, N, F, L, RNase, Table, WT, HIV-1, Vero, HIV, S1, E., A, RT, East, ϩ, Middle, PEDV, MAV-1, HA, miRNAs, ⌬, S2, SINV, RdRp, S., H1N1

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, its, they, i, his, us, them, my, he, itself, me, one, themselves, your, you, ourselves, nsp4, mine, her, y499, y322, nsp15, nsp10, hmgl, him, -luc

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?"

viral, human, respiratory, small, specific, immune, clinical, high, different, acute, severe, antiviral, anti, similar, novel, supplemental, potential, like, infected, infectious, important, low, several, many, new, significant, positive, cellular, single, multiple, genomic, present, large, molecular, higher, dependent, functional, negative, wild, recombinant, pathogenic, full, first, early, additional, genetic, lower, consistent, available, critical

also, however, previously, well, highly, significantly, respectively, therefore, directly, likely, even, first, together, recently, strongly, specifically, rather, prior, interestingly, furthermore, indeed, finally, closely, still, often, much, alone, less, similarly, differentially, relatively, least, approximately, double, subsequently, generally, currently, notably, especially, almost, rapidly, moreover, importantly, completely, clearly, already, overnight, additionally, primarily, briefly
