Distant Reader - keyword-singapore-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 2021-05-25 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:singapore. 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 63 item(s) in this carrel, and this carrel is 434,100 words long. Each item in your study carrel is, on average, 7,235 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 49. 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:

patients, singapore, cases, sars, health, disease, covid, also, study, clinical, nerve, cmt, may, data, respiratory, one, neuropathy, patient, public, within, control, new, two, hospital, time, high, information, influenza, risk, i, using, associated, number, first, infection, outbreak, however, well, treatment, development, case, pandemic, cidp, symptoms, based, measures, services, among, human, analysis

Using the three most frequent words, the three files containing all of those words the most are 2017 Peripheral Nerve Society Meeting July 8–12, 2017 Sitges, Barcelona, Spain, Impact of Disasters and Disaster Risk Management in Singapore: A Case Study of Singapore’s Experience in Fighting the SARS Epidemic, and A greener vision for vector control: The example of the Singapore dengue control programme.

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

hong kong, acute respiratory, respiratory syndrome, public health, severe acute, service industries, nerve conduction, healthcare workers, hiv aids, peripheral neuropathy, infectious diseases, health care, peripheral nerve, novel coronavirus, infectious disease, southeast asia, infection control, world health, coronavirus disease, neuropathic pain, cidp patients, schwann cells, health organization, vector control, united states, inflammatory demyelinating, social distancing, cord uid, doc id, respiratory tract, land use, mental health, gbs patients, confirmed cases, control measures, contact tracing, university hospital, chronic inflammatory, nervous system, conduction studies, symptom onset, sars outbreak, south korea, information seeking, risk factors, service industry, incubation period, information insufficiency, nerve fibers, new cases

And the three file that use all of the three most frequent phrases are Severe acute respiratory syndrome from the trenches, at a Singapore university hospital SARS: responding to an unknown virus, and Service industries, globalization, and urban restructuring within the Asia-Pacific: new development trajectories and planning responses.

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:

singapore, covid-19, sars, patient, hong, asia, kong, health, virus, sui, sss, school, nea, hospital, h1n1, fri, dengue, control, city, aedes, zealand, viral, vancouver, usa, urban, university, ttsh, ttr, tooth, tokyo, tianjin, taiwan, table, symptom, study, state, staphylococcus, spine, spi, south, site, simulation, shanghai, service, schwann, scdf, rna, risk, respiratory, rehabilitation

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 patients, and Adenoviral Infections in Singapore: Should New Antiviral Therapies and Vaccines Be Adopted? 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:

patients, nerve, neuropathy - 2017 Peripheral Nerve Society Meeting July 8–12, 2017 Sitges, Barcelona, Spain
singapore, sars, cases - Spatial super-spreaders and super-susceptibles in human movement networks
covid, patients, singapore - Adaptability and responsiveness: keys to operational measures in a regional hospital radiology department during the current COVID-19 pandemic
singapore, urban, asia - Service industries, globalization, and urban restructuring within the Asia-Pacific: new development trajectories and planning responses
influenza, respiratory, singapore - Risk factors for febrile respiratory illness and mono-viral infections in a semi-closed military environment: a case-control study

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, cases, disease, study, nerve, health, data, neuropathy, time, patient, control, risk, number, information, infection, treatment, influenza, outbreak, symptoms, case, measures, services, analysis, development, virus, pandemic, countries, service, studies, population, transmission, care, years, hospital, government, age, response, model, period, motor, syndrome, community, results, group, people, days, staff, use, tourism, city

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, included, shown, reported, associated, identified, increased, based, compared, providing, followed, developed, suggests, found, performed, reduced, led, made, affecting, seen, confirmed, present, caused, requiring, observed, took, detect, considered, related, described, assessed, known, remain, need, became, gave, resulted, support, testing, treat, indicated, implement, demonstrates, improved, determine, allows, infected, involving, emerging, sought

Proper Nouns

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

Singapore, SARS, COVID-19, CIDP, Asia, Kong, Hong, GBS, Health, CMT, University, China, Pacific, Department, M, Hospital, A, National, C, HIV, AIDS, Ministry, USA, Fig, March, Japan, April, Neurology, S, Schwann, PCR, J, IVIg, New, South, T, R, Marie, Charcot, World, Tooth, Medical, United, January, East, L, H1N1, Wuhan, MRI, Institute

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, he, them, his, her, she, my, us, you, me, itself, themselves, him, one, your, myself, ourselves, igg4, pbp, ours, yourself, ncs-4, imagej, herself, ≥13, uhfus, sin05-ntu-12, oneself, n=9, mg, itg2a+, in-/, cord-348129-tph0d5fl

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, respiratory, public, high, new, urban, acute, first, different, severe, peripheral, human, sensory, significant, positive, social, non, many, global, anti, higher, economic, early, medical, local, large, lower, important, axonal, viral, low, regional, covid-19, infectious, specific, similar, major, common, available, possible, small, potential, international, normal, negative, effective, national, several, key, distal

also, however, well, significantly, even, especially, respectively, therefore, highly, still, now, previously, often, relatively, less, first, recently, particularly, currently, moreover, later, together, rapidly, increasingly, already, largely, almost, specifically, instead, potentially, directly, clinically, subsequently, hence, furthermore, initially, far, least, frequently, quickly, mainly, worldwide, rather, commonly, yet, prior, much, mostly, just, strongly
