Hi All I came across a problem below when doing stemming and stem completion with package tm in R. Word "mining" was stemmed to "mine" with stemDocument(), and then completed to "miners"with stemCompletion(). However, I prefer to keep "mining" intact. For stemCompletion(), the default type of completion is "prevalent", which takes the most

Estimados, les escribo para consultar, lo siguiente: Estoy haciendo un trabajo de text mining y necesito importar una serie de textos para preprocesarlos, es decir eliminar los Stopwords, hacer stemming, eliminar signos de puntuación etc. Esto último lo puedo realizar con los datasets que trae la librería TM. Lo que no puedo lograr es importar texto desde algún medio a pesar que existe funciones

Hi, I installed the snow package on a unix box that has multiple cores. To be able to exploit the multiple cores (on one pc) do I still need to install the rmpi package (or rpvm). Another question, if i run a bayesian simulation on the multiple core after setting them up correctly (using snow), would you think there will be a noticeable speedup gain. Thanks, Saeed --- linux centos 4 dual core

I have a dataset of multiple variables and a response. For example, > str(x) 'data.frame': 3557238 obs. of 44 variables: $ response : Factor w/ 2 levels $ var2: Factor w/5000 levels If var2 for example is a factor with 5000 levels, what is the best approach to determine which of these levels is the most important to include in building the model, and which ones to discard.

Hello, I want to use the SnowballStemmer on a collection of plain text documents. However, when I apply it to my corpus using the tm_map function it only stems the last word of each document (The problem is the for wordStem and stemDocument does not work at all).  An example: > path <- c("c:\path\to\directory")       # collection of plain text documents > corp <-

If we use the ROCR package to find the accuracy of a classifier pred <- prediction(svm.pred, testset[,2]) perf.acc <- performance(pred,"acc") Do we?find the maximum accuracy?as follows?(is there a simplier way?): > max(perf.acc at x.values[[1]]) Then to find the cutoff point that maximizes the accuracy?do we do the following?(is there a simpler way): > cutoff.list <-

Dear useRs, a first version of tm has just been released on CRAN. tm provides a sophisticated framework for text mining applications within R. It offers functionality for managing text documents, abstracts the process of document manipulation and eases the usage of heterogeneous text formats in R. An advanced metadata management is implemented for collections of text documents to alleviate the

Dear all, I have some troubles using the stemming algorithm provided by the tm (text mining) + Snowball packages. Here is my config: MacOS 10.5 R 2.12.0 / R 2.13.1 / R 2.14.1 (I have tried several versions) I have installed all the needed packages (tm, rJava, rWeka, Snowball) + dependencies. I have desactivated AWT (like written in

| I can think of two disadvantages of a newsgroup | | 1) Access | Everyone with an email address can sub_scribe to the R mailing lists. | However, not everyone has a news feed. I don't. Everyone who has access to the internet can also have a news-account.

Hi everyone, Are the wine-users mailing list and news:comp.emulators.ms-windows.wine newsgroups still connected ? I've subscribed to the mailing list, then posted a message on the newsgroup ( news:44f3c571$0$164$a3f2974a@nnrp1.numericable.fr ) but I don't see it on the mailing list nor on gmane.org . That seems also true for many other messages on news:gmane.comp.emulators.wine.user .
