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:antibiotic. 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 53 item(s) in this carrel, and this carrel is 373,319 words long. Each item in your study carrel is, on average, 7,043 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 40. 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:

antibiotic, antibiotics, patients, resistance, use, treatment, infection, infections, health, may, clinical, acute, therapy, also, study, resistant, antimicrobial, disease, bacteria, pneumonia, new, bacterial, respiratory, group, care, used, one, drug, risk, human, studies, however, patient, children, associated, based, community, diagnosis, high, common, development, infectious, pathogens, will, hospital, activity, diseases, influenza, including, i

Using the three most frequent words, the three files containing all of those words the most are Antibiotic Resistance: Moving From Individual Health Norms to Social Norms in One Health and Global Health, The Political Economy of US Antibiotic Use in Animal Feed, and Infectious Diseases Society of America/American Thoracic Society Consensus Guidelines on the Management of Community-Acquired Pneumonia in Adults.

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

antibiotic resistance, antibiotic use, united states, acute bronchitis, antimicrobial resistance, respiratory tract, acquired pneumonia, infectious diseases, public health, antibiotic therapy, primary care, antibiotic treatment, tract infections, antibiotic prescribing, staphylococcus aureus, resistance genes, health care, escherichia coli, resistant bacteria, respiratory infections, otitis media, streptococcus pneumoniae, upper respiratory, risk factors, systematic review, infectious disease, gut microbiota, controlled trial, human health, sore throat, animal health, acute respiratory, antimicrobial agents, drug resistance, helicobacter pylori, urinary tract, one health, tract infection, antimicrobial stewardship, antibiotic prescription, new antibiotics, randomized controlled, clinical practice, doc id, cord uid, lower respiratory, hospitalized patients, antimicrobial therapy, streptococcal pharyngitis, clostridium difficile

And the three file that use all of the three most frequent phrases are Antibiotic Resistance: Moving From Individual Health Norms to Social Norms in One Health and Global Health The Political Economy of US Antibiotic Use in Animal Feed, and Microbiology of hospital wastewater.

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:

antibiotic, patient, infection, resistance, treatment, amr, acute, united, human, hiv, therapy, states, health, group, gram, drug, dna, disease, uti, pneumonia, pcr, new, microbiota, infectious, icu, gut, gene, gabhs, fda, cell, cause, cap, animal, wwtp, western, wastewater, virus, vietnam, veterinary, urti, uri, trinidad, threat, target, study, streptomyces, streptococcal, ssi, sor, social

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 antibiotic, and Optimizing Economic Outcomes in Acute Exacerbations of Chronic Bronchitis 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. patients - Infectious Diseases Society of America/American Thoracic Society Consensus Guidelines on the Management of Community-Acquired Pneumonia in Adults
  2. antibiotic - Antibiotic Resistance: Moving From Individual Health Norms to Social Norms in One Health and Global Health
  3. antibiotics - Main trends in the design of semi-synthetic antibiotics of a new generation

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. patients, antibiotic, treatment - Infectious Diseases Society of America/American Thoracic Society Consensus Guidelines on the Management of Community-Acquired Pneumonia in Adults
  2. antibiotic, health, antibiotics - The Political Economy of US Antibiotic Use in Animal Feed
  3. patients, acute, treatment - Infectious Diseases
  4. antibiotics, antibiotic, resistance - Main trends in the design of semi-synthetic antibiotics of a new generation
  5. antibiotic, flagellin, treatment - Microbial drug discovery: 80 years of progress

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?":

antibiotics, patients, resistance, treatment, use, infection, infections, therapy, bacteria, pneumonia, study, health, disease, care, group, risk, drug, studies, children, diagnosis, community, pathogens, activity, patient, days, symptoms, development, years, time, virus, hospital, influenza, adults, results, cases, diseases, evidence, analysis, pneumoniae, management, animal, fever, drugs, agents, bronchitis, cell, guidelines, antibiotic, tract, data

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:

used, including, increasing, treating, causing, show, reduced, based, associated, develops, reported, found, requires, acquired, providing, considered, given, compared, recommend, making, following, produces, see, prescribe, improving, lead, identified, result, need, controlled, receive, indicated, occurs, prevent, suggested, decreased, known, related, involved, taking, becomes, containing, remained, demonstrated, emerged, presents, detect, limiting, affect, performed

Proper Nouns

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

Health, United, States, •, S., AR, AMR, UTI, amoxicillin, CAP, Staphylococcus, MRSA, PCR, HIV, NDM-1, Antimicrobial, ICU, FDA, GP, A, C, mg, E., Society, Escherichia, America, ABRS, National, China, US, World, Pseudomonas, Infectious, Table, flagellin, AECB, Helicobacter, UK, New, GABHS, Disease, M., HWW, H., Diseases, CDC, B, ±, TB, Global

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, they, its, our, i, them, you, us, he, my, his, one, itself, themselves, me, him, your, her, ourselves, she, 's, puc, mg, himself, herself, 63a, yourself, thy, thine, thee, ours, oneself, myself, cord-295605-c6z9n3ij

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?"

antibiotic, clinical, acute, resistant, bacterial, respiratory, new, antimicrobial, human, high, common, infectious, important, different, positive, primary, viral, severe, many, effective, specific, oral, first, negative, recent, significant, low, diagnostic, public, global, medical, major, non, appropriate, lower, several, chronic, rapid, available, higher, initial, pneumococcal, present, microbial, randomized, early, active, general, economic, natural
