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 2021-06-01 by Eric Morgan <emorgan@nd.edu>. The carrel was created using the Distant Reader gutenberg process, and the input was the result of a query applied to a local mirror of Project Gutenberg -- facet_subject:"Central America". Then, for future reference, the results were saved to a Zip file complete with rudimentary bibliographics. The name of the file is input-file.zip. The Zip file was then unpacked and the contents saved to a cache as well as a directory 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 14 item(s) in this carrel, and this carrel is 552,348 words long. Each item in your study carrel is, on average, 39,453 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 77. 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:

one, will, now, jack, de, two, ku, brown, like, don, km, white, species, hyla, length, just, dark, time, back, first, way, much, well, see, may, know, men, man, specimens, mm, philip, long, made, us, also, get, found, three, though, think, small, come, still, place, great, little, ummz, go, good, even

Using the three most frequent words, the three files containing all of those words the most are The West Indies and the Spanish Main, Life Blood, and The Harlequin Opal: A Romance. Vol. 2 (of 3).

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

costa rica, dark brown, don hypolito, central america, vent length, per cent, de la, don miguel, alex goddard, natural history, posterior surfaces, de los, hyla microcephala, don juan, caudal musculature, metatarsal tubercle, west indies, creamy white, united states, ventral surfaces, total length, don rafael, new york, kansas sci, tarsal fold, white stripe, let us, per second, body length, inner metatarsal, anal opening, smilisca baudini, chalchuih tlatonac, pacific lowlands, subarticular tubercles, dermal fold, south america, hyla bistincta, upper lip, dorsal surfaces, breeding males, caribbean lowlands, pale brown, replied jack, puerto viejo, padre ignatius, vent lengths, yellowish tan, mi amigo, dark stripe

And the three file that use all of the three most frequent phrases are Neotropical Hylid Frogs, Genus Smilisca The Systematics of the Frogs of the Hyla Rubra Group in Middle America, and The West Indies and the Spanish Main.

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:

hyla, méxico, america, ummz, rica, indians, xuarez, tlatonac, tim, señor, rafael, philip, juan, jack, guatemala, don, costa, usc, san, peter, padre, new, janjalla, hypolito, doña, dolore, city, amnh, acauhtzin, yucatan, york, west, vol, velasquez, usnm, uimnh, trinidad, totatzine, thomas, taylor, steve, states, st., spanish, smith, smilisca, serafina, senor, sarah, río

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 said, and Middle American Frogs of the Hyla microcephala Group 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. said - The West Indies and the Spanish Main
  2. ku - Neotropical Hylid Frogs, Genus Smilisca
  3. la - Notes on the Bibliography of Yucatan and Central America Comprising Yucatan, Chiapas, Guatemala (the Ruins of Palenque, Ocosingo, and Copan), and Oaxaca (Ruins of Mitla)

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. jack, said, don - The West Indies and the Spanish Main
  2. ku, km, species - Neotropical Hylid Frogs, Genus Smilisca
  3. just, like, going - Life Blood
  4. length, mm, brown - Descriptions of New Hylid Frogs From Mexico and Central America
  5. la, guatemala, yucatan - Notes on the Bibliography of Yucatan and Central America Comprising Yucatan, Chiapas, Guatemala (the Ruins of Palenque, Ocosingo, and Copan), and Oaxaca (Ruins of Mitla)

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?":

was, is, be, are, have, had, were, do, been, said, has, ''s, did, know, see, made, get, found, think, come, having, go, going, say, being, take, make, let, am, got, came, looked, ''d, thought, ''m, does, went, saw, took, seen, look, tell, turned, ''ve, ''re, done, told, find, left, felt

Proper Nouns

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

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?"

i, it, he, his, you, they, my, we, me, her, their, she, him, them, our, its, your, us, himself, myself, themselves, one, itself, ourselves, herself, yourself, mine, thee, ''s, yours, thy, ours, oneself, ye, tympanum, thyself, theirs, indistinct, history._--this, hers, hardyi, ay, á, yourselves, you,--in, you''ll, ya, with--, tympanum/, remarks._--the

Adjectives & Verbs
