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

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", +

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

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.

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 put 'export NOAWT=1' in my package's 'configure' script, and 'R CMD INSTALL MyPackage' returns with no errors. However when I do 'R CMD CHECK MyPackage', the installation test fails, because

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 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

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

Hi All, I have been trying to do some text analytics in R using tm package. I have installed and loaded the package, along with dependencies (slam, rWeka,rjava). When I try to run a tm_map command, it gives me "Error in .jnew(name) : java.lang.NoClassDefFoundError: weka/core/stemmers/SnowballStemmer" error. Can someone please throw some light on this?. Am I missing out on something?

I just bought a new machine and installed the latest release of R 2.15.1 two days ago. Loaded libraries yesterday (all reported successful loads).

Hello everyone! I'm working this school project in R and everything was fine until I moved to other computer. The problem is that I can't load few libraries like "Snowball" or "openNLP". Like I said, everything was fine on other computers, but at the moment, the only computer is this one that I'm finding error on. So here is the problem: I install library

Hi listeRs, Maybe I have missed something, but I am facing a problem I don't understand even after reading archives and manuals (…maybe not carefully enough !) : On my PC (64-bit OS, Intel Xeon CPU , two L5506@2.13 GHz processors, 12 Go RAM) under Windows 7 SP1, I run both 32-bit (i386-pc-mingw32/i386) and 64-bit (x86_64-pc-mingw32/x64) version 2.14.2 (2012-02-29) of R, packages

Hello. I'm interested in creating a Hebrew stemmer to use with Xapian. Hebrew is a complicated language to stem, as it uses the semitic "root" system, rather than prefixes and suffixes, and has many irregularities in accidence (morphology). Fortunately, two bright fellows from the Technion University in Israel have already created a Hebrew morphological analyzer as part of their

Hi everyone, I was working on the Paice-Husk Stemmer, which is a Bite Size Project for Xapian, and I have created a C++ as well as Snowball version of it. I read the algorithm, and picked the rules from here: http://www.comp.lancs.ac.uk/computing/research/stemming/paice/descript.htm The C++ code takes rules as input from a file and generates the stem of given word, whereas the Snowball version

On Tuesday, I replaced the romanian1 and romanian2 stemmers in Xapian-core with Martin's new romanian stemmer. At the time, I also updated the stemming test data (by re-generating the output file using snowball's "stemwords" utility), and I clearly remember re-running the testsuite at the time and checking that all tests passed. Now, when I run make check, stemtest fails
