There is no package called 'quanteda', How can I extract keyword/keywords RRS feed

  • Question

  • I need to extract particular keywords (e.g. bag_of_keywords <- c("apple", "  red apple", "I love apple.") from comment data, as well the user who made the comment. For example

    -------------------------|--------------------------------------------------------

    user                                                                    comment

    _____________________|________________________________________________ 

    user1                                     tom has an apple tree full of big apples

    user2                         I am going to NC tomorrow

    user3                          I eat apple everyday

    how can I do it in AML?

    Thanks.

  • Hi Bipul,

    Have you tried to import the R package (quanteda)? https://social.msdn.microsoft.com/Forums/en-US/2688bccc-2f38-4611-b466-f66edc0b43c5/using-bioconductor?forum=MachineLearning

    You might also need to bring in all the package dependencies if they are not already pre-installed in Azure ML. Use this code to check the latest list of packages that are preinstalled.

    data <- data.frame(installed.packages())
    # Select data.frame to be sent to the output Dataset port
    maml.mapOutputPort("data");

    It looks like the package has a list of dependencies: https://cran.r-project.org/web/packages/quanteda/index.html

    Regards,
    Jaya.

  • Hello Jaya,

    Thank you very much for your genius comment. It took me several hours to understand the word "package dependencies", I found quanteda package requires two other packages, Rcpp and RcppArmadillo. So what I did, attached all these three packages in .zip and connect with my R script. But finally I found Azure ML is 3.1.0 when quanteda needs 3.2.2. Please help, how else I can find the keyword/words from my data. I am following my another question as well to clarify my purpose.

     

    I am really happy for your help.

    BR,

    Bipul
