QUESTION
I'm a fairly beginner in Py, tho I am trying to automate a task in something, we are dubbing a webtoon series, and we need to train since we are quite a lot, I need a program, that check the user input for a number, then check multiples list (episode 1 (3) ) for the number of characters in it.
I also need if someone is willing to help more, to do this with name, I nearly got it, then got stuck, and I got mad so I deleted everything, but ht code was bad, so no remorse. so you put a bunch of names, and it will output the episodes with these names in it.

QUESTION
I have a large dataframe consisting of tweets, and keyword dictionaries loaded as values that have words associated with morality (kw_Moral
) and emotion (kw_Emo
). In the past I have used the keyword dictionaries to subset a dataframe to get only the tweets that have one or more of the keywords present.
For example, to create a subset with only those tweets that have emotional keywords, I loaded in my keyword dictionary...
...ANSWER
Answered 2018-Dec-12 at 14:02Your requirement would seem to lend itself to a matrix type output, where, for example, the tweets are rows, and each term is a column, with the cell value being the number of occurrences. Here is a base R solution using gsub

QUESTION
I am trying to setup a script to send email, and I want to add the Senders Name (depending on who runs the script) to the Email Body.
Emailing works, and I'm setup on Juypter, runing Python 3, emailing from Outlook.
My code is below. The mail.SenderName is the part I want to pull the name from the Outlook account of the user. In VBA this would be equivalent to using Application.UserName

- Use the NameSpace.CurrentUser property which returns the display name of the currently logged-on user as a
Recipient
object.
QUESTION
I have a large dataframe consisting of tweets, and a keyword dictionary loaded as a list that has words and word stems associated with emotion (kw_Emo
). I need to find a way to count how many times any given word/word stem from kw_Emo
is present each tweet. In kw_Emo
, word stems are marked with an asterisk ( * ). For example, one word stem is ador*
, meaning that I need to account for the presence of adorable
, adore
, adoring
, or any pattern of letters that starts with ador…
.
From a previous Stack Overflow discussion (see previous question on my profile), I was greatly helped with the following solution, but it only counts exact character matches (Ex. only ador
, not adorable
):
Load relevant package.
library(stringr)
Identify and remove the
*
from word stems inkw_Emo
.for (x in 1:length(kw_Emo)) { if (grepl("[*]", kw_Emo[x]) == TRUE) { kw_Emo[x] <- substr(kw_Emo[x],1,nchar(kw_Emo[x])-1) }
}Create new columns, one for each word/word stem from
kw_Emo
, with default value 0.for (x in 1:length(keywords)) { dataframe[, keywords[x]] <- 0}
Split each Tweet to a vector of words, see if the keyword is equal to any, add +1 to the appropriate word/word stems' column.
for (x in 1:nrow(dataframe)) { partials <- data.frame(str_split(dataframe[x,2], " "), stringsAsFactors=FALSE) partials <- partials[partials[] != ""] for(y in 1:length(partials)) { for (z in 1:length(keywords)) { if (keywords[z] == partials[y]) { dataframe[x, keywords[z]] <- dataframe[x, keywords[z]] + 1 } } } }
Is there a way to alter this solution to account for word stems? I'm wondering if it's possible to first use a stringr pattern to replace occurrences of a word stem with the exact characters, and then use this exact match solution. For instance, something like stringr::str_replace_all(x, "ador[a-z]+", "ador")
. But I'm unsure how to do this with my large dictionary and numerous word stems. Maybe the loop removing [*]
, which essentially identifies all word stems, can be adapted somehow?
Here is a reproducible sample of my dataframe, called TestTweets
with the text to be analysed in a column called clean_text
:
dput(droplevels(head(TestTweets, 20)))

QUESTION
I'm trying to build a naive bayes based classifier for 1000 positive+negative labled IMDB reviews (txt_sentoken) and weka API for Java.
As I wasn't aware of StringToWordVector
, which basically provides a BagOfWords model that reaches an 80% accuracy, so I did the vocabulary building and vector creation myself, with an accuracy of only 75% :(
Now I'm wondering why my solution is performing so much worse.
1) From my 2000 reviews, I build the BagOfWords:
...ANSWER
Answered 2017-Dec-28 at 07:18Reading through Weka's StringToWordVector
documentation, there seem to be a couple of implementation details different than yours. Here are the top two, based on how likely they are to be the reason for the performance difference you see, in my opinion:
- It seems that by default, the resulting vector is boolean (i.e. noting the existence of a word, rather than number of occurrences)
- If the class attribute is set before vectorizing the text, a separate dictionary is built for each class, then all dictionaries are merged.
While any of them (or other, more minor differences) could be the culprit, my bet is on the second point.
The built-in class allows setting and unsetting each of these options; you could try re-running the 80% version using StringToWordVector
with the -C option to use number of occurences rather then a boolean value, and with -O, to use a single dictionary across both classes.
This should allow you to verify whether any of these is indeed the culprit.
EDIT: Regarding the first point, i.e. counting occurences vs. noting word existence (also called Bernoulli and multinomial models), there were several academic papers at the 90s which looked into the differences, e.g. here and here. While usually the multinomial model works better, there are also opposite cases, depending on corpus and classification problem.
QUESTION
I'm sure this has to be documented somewhere, but I'm so new at html that I can't figure out where to look, so feel free to just direct me to the correct reading if it's something obvious. As a note, I code in several languages, but mostly things like python or LaTeX, nothing like html. I have included my attempt at the bottom, but tried to include what I could in terms of my design setup and what problems I am running into. Any solutions to any of the listed problems would be appreciated :)
The setup;
I need to form gigantic table of information that will be populated based on a JSON string given on another webpage. I am currently using javascript to parse the JSON string and form a single global object of my own that has all the relevant information (the JSON string that the user will plug in is huge and I only need a relatively small portion of it). The created object has the following form;

Answered 2017-Dec-13 at 20:26Without doing it for you - here are the angles that I would solve these problems
You can cache it locally to a cookie as a string of the literal HTML, but the process really isn't that expensive. If the length is a concern - maybe think about breaking it down into rendering the first X amount of elements.
Create a class for the cell.
[your data]
and then in your css:.dropdown-cell{[your css rules}
will format only the table cells that have the class dropdown-cell. edit: CSS classes work the same way they would if it was aor
or .dropdown{ height: 50px; width: 200px; background-color: gray; } .dropdown-option{ background-color: lightgray; } A B C
- If I'm understanding it right, if you want these edits to be bound to some object. You should create a class for each row, and then run a function onChange or onClick or onKeyup of these editable events and modify the related Object.
