kandi X-RAY | tidytext Summary

tidytext is a R library typically used in Analytics, Data Visualization applications. tidytext has no bugs, it has no vulnerabilities and it has medium support. However tidytext has a Non-SPDX License. You can download it from GitHub.

Authors: Julia Silge, David Robinson License: MIT. Using tidy data principles can make many text mining tasks easier, more effective, and consistent with tools already in wide use. Much of the infrastructure needed for text mining with tidy data frames already exists in packages like dplyr, broom, tidyr, and ggplot2. In this package, we provide functions and supporting data sets to allow conversion of text to and from tidy formats, and to switch seamlessly between tidy tools and existing text mining packages. Check out our book to learn more about text mining using tidy data principles.

            step_mutate with textrecipes tokenlists
            Asked 2022-Mar-31 at 13:03

            I'm doing NLP with the tidymodels framework, taking advantage of the textrecipes package, which has recipe steps for text preprocessing. Here, step_tokenize takes a character vector as input and returns a tokenlist object. Now, I want to perform spell checking on the new tokenized variable with a custom function for correct spelling, using functions from the hunspell package, but I get the following error (link to the spell check blog post):

            There isn't a canonical way to do this using {textrecipes} yet. We need 2 things, a function that takes a vector of tokens and returns spell-checked tokens (you provided that) and a way to apply that function to each element of the tokenlist. For now, there isn't a general step that lets you do that, but you can cheat it by passing the function to custom_stemmer in step_stem(). Giving you the results you want

            This can't work, because facet_grid would only have one shared x-axis. But the orders are different in every facet. You want facet_wrap. For example like this:

            Asked 2022-Feb-10 at 15:45

            WHAT I WANT: I want to count co-occurrence of two words. But I don't care the order they appear in the string.

            MY PROBLEM: I don't know how to deal When two given words appear in different order.

            SO FAR: I use unnest_token function to split the string by words using the "skip_ngrams" option for the token argument. Then I filtered the combination of exactly two words. I use separate to create word1 and word2 columns. Finally, I count the occurrence.

            Errors in counting + combining bing sentiment score variables in Tidytext?
            Asked 2022-Feb-02 at 00:38

            I'm doing sentiment analysis on a large corpus of text. I'm using the bing lexicon in tidytext to get simple binary pos/neg classifications, but want to calculate the ratios of positive to total (positive & negative) words within a document. I'm rusty with dplyr workflows, but I want to count the number of words coded as "positive" and divide it by the total count of words classified with a sentiment.

            I tried this approach, using sample code and stand-in data . . .

            Two shiny widgets cannot be used at the same time to subset a dataframe
            Asked 2022-Jan-10 at 11:13

            I have the shiny app below in which I create a wordcloud. This wordcloud is based on the shiny widgets in the sidebar. The selectInput() subsets it by label, the Maximum Number of Words: is supposed to show the maximum count of words that will be displayed in the wordcloud and the Minimun Frequency the minimum frequency that a word needs to be displayed. Those widgets are reactive and are based on the df() function which creates the dataframe needed for the wordcloud. The proble is that when I subset using input$freq the dataframe has fewer rows than needed to subset with input$max as well so nothing is displayed.

            I'm not totally sure, but since you say

            when the app is launched nothing is displayed

            It could be related to this bug.

            I created this solution.

            This looks complicated, but it really isn't. Simply define the following function (wordcloud2a()), then use it where you'd normally use wordcloud2().

            The 3rd argument to unnest_tokens is the input i.e the column in the dataframe which needs to be split. You have passed it as text but there is no text column in your data.

            Asked 2021-Nov-22 at 12:02

            The unnest_tokens function of the package tidytext is supposed to keep the other columns of the dataframe (tibble) you pass to it. In the example provided by the authors of the package ("tidy_books" on Austen's data) it works fine, but I get some weird behaviour on these data.

            You need to ungroup your data. In the argument for collapse, you can see that grouping data automatically collapses the text in each group when not dropping:

            Grouping data specifies variables to collapse across in the same way as collapse but you cannot use both the collapse argument and grouped data. Collapsing applies mostly to token options of "ngrams", "skip_ngrams", "sentences", "lines", "paragraphs", or "regex".

            I'm assuming this is your expected behaviour:
