Distant Reader - journal-worldNeurosurg-cord

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:"World Neurosurg". 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 57 item(s) in this carrel, and this carrel is 109,848 words long. Each item in your study carrel is, on average, 1,927 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 50. 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, patients, pandemic, neurosurgical, cases, neurosurgery, care, health, surgical, surgery, may, also, patient, coronavirus, residents, neurosurgeons, practice, disease, will, medical, study, case, resident, world, reported, time, clinical, spine, system, training, cord, hospital, sars, cov, procedures, risk, elective, survey, data, education, impact, using, respondents, one, number, treatment, new, spinal, use, authors

Using the three most frequent words, the three files containing all of those words the most are Neurosurgery Practice During Coronavirus Disease 2019 (COVID-19) Pandemic, Scoring system to triage patients for spine surgery in the setting of limited resources: Application to the COVID-19 pandemic and beyond, and Letter: Changes to neurosurgery resident education following onset of the COVID-19 pandemic.

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

coronavirus disease, world neurosurg, health care, doc id, neurosurg doi, cord uid, novel coronavirus, united states, scoring system, smart glasses, skull base, protective equipment, neurosurgery residents, intensive care, covid pandemic, neurosurgical practice, personal protective, spine surgery, social distancing, resident education, spinal cord, neurosurgical patients, operating room, acute respiratory, new york, neurosurgery department, ward rounds, minimally invasive, severe acute, respiratory syndrome, mental health, operative videos, elective cases, health system, care workers, back pain, social media, ischemic stroke, syndrome coronavirus, health organization, carotid artery, world health, bone formation, authors declare, public health, critical care, cavernous sinus, neurosurgical procedures, cord injury, surgical procedures

And the three file that use all of the three most frequent phrases are Neurosurgery Practice During Coronavirus Disease 2019 (COVID-19) Pandemic Letter to the Editor: “Beyond Containment: Tracking the Impact of Coronavirus Disease 2019 (COVID-19) on Neurosurgery Services in Iraq”, and Emergent carotid artery stenting following intravenous alteplase infusion after rapid negative diagnosis for COVID-19 by loop-mediated isothermal amplification assay: A case report.

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, patient, sars, resident, pandemic, case, practice, pain, latin, icu, covid, coronavirus, wfns, ward, video, united, technology, system, surgery, spinal, smart, round, respondent, report, procedure, present, plan, operative, opd, neurosurgical, neurosurgeon, multidisciplinary, march, lsc, lateral, lamp, knowledge, july, italy, interview, hospital, glass, geneva, fusion, ednac, drape, device, depression, cov-2, china

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 Letter to the Editor: SARS-CoV-2 and Traumatic Cervical Acute Spinal Cord Injury: An Appraisal 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:

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:

covid, pandemic, patients - Neurosurgical practice during the SARS-CoV-2 pandemic: a worldwide survey
covid, patients, pandemic - Neurosurgery Practice During Coronavirus Disease 2019 (COVID-19) Pandemic
videos, surgery, will - The Future of Skull Base Surgery: A View Through Tinted Glasses
residents, neurosurgery, training - Neurosurgical Interactive Teaching Series: A Multidisciplinary Educational Approach
ednac, spinal, sinus - Clinical anatomy of the extradural neural axis compartment: a literature review

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?":

patients, pandemic, cases, care, surgery, health, residents, neurosurgeons, practice, case, patient, study, time, system, procedures, disease, risk, survey, spine, training, respondents, number, data, hospital, authors, education, coronavirus, period, programs, treatment, volume, use, impact, infection, hospitals, management, healthcare, emergency, changes, results, resources, videos, stroke, outbreak, analysis, level, years, countries, transmission, staff

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, reported, including, provide, increasing, followed, performed, requiring, present, based, needed, reducing, show, affects, found, compare, regarding, develop, continues, considered, made, covid-19, allowed, led, confirmed, related, remain, see, limit, receiving, gives, associated, take, known, expect, treat, change, caused, recommended, learning, involving, describes, decreased, work, undergo, identify, ensuring, operating, maintaining, improved

Proper Nouns

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

COVID-19, neurosurgery, SARS, CoV-2, Neurosurgery, Coronavirus, World, EDNAC, COVID, Pandemic, Neurosurgical, PPE, Neurosurg, China, •, Italy, ICU, DOI, Health, United, States, Disease, March, New, J, Letter, India, April, sha, University, Medical, Impact, Hospital, nan, Department, York, LSC, neuro, Wuhan, Table, Care, CT, Education, American, Society, Organization, May, Lombardy, Surgeons, Spine

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, their, our, it, they, its, them, us, he, itself, his, your, you, she, i, her, themselves, one, ourselves, interest.https://doi.org/10.1016/j.wneu.2020.07.018

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?"

neurosurgical, surgical, covid-19, medical, clinical, elective, significant, high, spinal, non, resident, operative, many, positive, social, new, acute, covid, current, emergent, first, different, urgent, potential, low, virtual, possible, patient, severe, personal, essential, educational, available, specific, public, novel, private, respiratory, important, general, able, multiple, key, financial, due, academic, protective, present, human, several

also, well, however, even, therefore, especially, significantly, additionally, rapidly, already, minimally, worldwide, still, almost, particularly, less, completely, similarly, previously, nearly, overall, furthermore, approximately, widely, prior, currently, relatively, increasingly, specifically, highly, first, respectively, recently, now, moreover, likely, rather, potentially, often, back, just, hence, commonly, finally, primarily, initially, globally, easily, newly, critically
