similar to: Troubles with stemming (tm + Snowball packages) under MacOS

I too have this problem. Everything worked fine last year, but after updating R and packages I can no longer do word stemming. Unfortunately, I didn't save the old binaries, otherwise I would just revert back. Hoping someone finds a solution for R on Windows. Thanks! There is a potential solution for R on Mac OS from Kurt Hornik copied below, but I cannot get this to work on Windows.

Dear Forum, when I try to use SnowballStemmer() I get the following error message: "Could not initialize the GenericPropertiesCreator. This exception was produced: java.lang.NullPointerException" It seems to have something to do with either Snowball or RWeka, however I can't figure out, what to do myself. If you could spend 5 minutes of your valuable time, to help me or give me a

Hola a todos! Tengo algunos problemas con el tamaño de la matriz de términos que obtengo. Los comandos que utilizo son los siguientes: # carga librerias library(tm) library(wordcloud) library(Rstem) library(Snowball) # lee el documento UTF-8 y lo convierte a ASCII txt <-

Hi, All: I am new to R and tm package.

Hi! I was trying to install RWeka to be able to use SnowballStemmer in a Mac OS X 10.6.7 environment... but coudn't do it... I get error messages after: > library(RWeka); > install(Snowball); > ## Test the supplied vocabulary for the default stemmer ('porter'): > source <- readLines(system.file("words", "porter","voc.txt", +

I am using code that previously worked to remove stopwords using package "tm". Even manually adding "the" to the list does not work to remove "the". This package has undergone extensive redevelopment with changes to the function syntax, so perhaps I am just missing something. Please see my simple example, output, and sessionInfo() below. Thanks!

Hi all, I am trying to do some text mining with twitter and I am getting the error: Error in structure(names(sapply(possibleCompletions, "[", 1)), names = x) : 'names' attribute [1] must be the same length as the vector [0] When I use tm_map. Has anyone had/seen this error before? The code I have is shown below and this error only occurs with #qantas, hashtags like #asx,

I tried making a wordcloud of Obama's State of the Union address using the tm package to process the text sotu <- scan(file="c:/R/data/sotu2012.txt", what="character") sotu <- tolower(sotu) corp <-Corpus(VectorSource(paste(sotu, collapse=" "))) corp <- tm_map(corp, removePunctuation) corp <- tm_map(corp, stemDocument) corp <- tm_map(corp,

No es un problema de tm ni de SnowfallC ni de mcapply (por el path utilizas linux, en windows mcapply según el manual no va bien) No defines bien los objetos que pasas. Pasas doc.corpus en lugar de corpus ( o asignas a corpus en lugar de a doc.corpus) . Depura los programas cuando salga un error de objeto, como te pone en el Error que pasas . Temporalmente lo tienes arreglado en

Hi! I am going to use non-snowball russian stemmer with Xapian. There is a good one at http://www.aot.ru. I've found that current implementation of Xapian::Stem does not allow it (there is no public interface for Xapian::Stem::Internal). Do you apply patches? Are there any recommendations for writing patches? Regards, Oleg Obolenskiy highpower at mail.ru

Creo que lo que quieres hacer necesita esta línea de código justo después de cargar el paquete tm: inmortal = unlist(strsplit(inmortal, " ", fixed = T)) De esta forma, trabajas con palabras, y NO con las frases enteras...

Muchas gracias isidro, a la noche reinstalo R y os digo si me ha funcionado. Perdona mi ignorancia de novato pero no he entendido muy bien eso de avisar al desarrollador.

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 <-

I'm trying to get ready to submit a package to CRAN, but in order for the package to install on OS X, I need to temporarily set the environment variable NOAWT=1.

I tried using the "Snowball" package for performing stemming in text mining. But when I tried to load the package the following error is thrown: Error : .onLoad failed in loadNamespace() for 'Snowball', details: call: NULL error: .onLoad failed in loadNamespace() for 'rJava', details: call: hive[[hive$CurrentVersion]] error: attempt to select less than one

The Java error when attempting to use the stemmers in the Snowball or tm packages on Windows machines is caused by Quicktime. See prior posts in this thread. The workaround is to uninstall Quicktime. After much trial and error on machines spanning WinXP/2k/Vista/7, I finally verified this as follows: 1) Fresh installation of Windows/Java/R. Snowball package works perfectly. 2) Install Quicktime.

Hi!
