similar to: Problem with Snowball & RWeka

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

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 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 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.

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

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

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

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

Hey guys Hi :) I've implemented a PaiceHusk stemmer externally So what I am doing right now is passing a pointer to my StemPaiceHusk class(which in turn has been subclassed from Stemimplementation) to the Stem::Stem(StemImplementation *p) constructor .So basically,I have to include "paicehusk.h" in my indexer .However,I now want to make it a part of the Xapian library so that I

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

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

Howdy Gurus again Thanks to Tony.Breyal, I was able to writing the following script for analyzing a text document. But I got an error with "tm' package. I don't why I got the error from the R script below. I think I followed proccess of R tm manual. I use R v2.8.1. and tm_0.3-3.zip under Win XP. Thanks in advance, Kum Hwang > # setting directory > my.path

Hi, I need to modify the stemming for a couple of words (a blacklist) and for all the other to use the usual snowball stemmer. The "natural" way of doing it would be to derive from Stem and override operator ()... but I am using *python-bindings*. Would this be possible? If not I have two other solutions in mind: - add a custom stemmer to Xapian - write custom index & search

Hi, I'm using Xapian bindings for Python in my project. How could I use a custom stemmer instead of the included one (Snowball)? The one I'm looking at right now is Hunspell (http://hunspell.sourceforge.net/) which has Python bindings (http://code.google.com/p/pyhunspell/). Thanks in advance, Eugene

Hello, I am student from University of Science and Technology in Cracow. I would like to ask you some questions about Xapian, because it is one of few search engines I am testing. 1. What type of stemmer is used in Xapian? Are You able to write some important features applied to Xapian? 2. We must use stemming for polish language. I read on Your webpage what languages include Xapian. There is no

Hi, is there a xapian stemmer suitable for polish or czech languages? Thanks, Torsten

Hello, As mentioned on the project ideas page, Adding more support for stemmer algorithm, i found an implementation of Krovetz Stemmer Algo in C++ but before working on it to merge it into xapian, i needed help in recognizing the license information associated with the source code. To avoid further licensing issues kindly someone check the link

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). While running scripts, rJava and Snowball would not load. Here is Snowball successful install: > utils:::menuInstallPkgs() trying URL 'http://cran.cs.wwu.edu/bin/windows/contrib/2.15/Snowball_0.0-8.zip' Content type

Hello xapian devs, I had shown interest in writing a krovetz stemmer for xapian and spoke to James Aylett about it. Since it was hard to code the stemmer in snowball, I came up with a C++ implementation of the stemmer. But since it is a dictionary based stemmer, im having problems on deciding how to create the dictionary. I did check out some of the implementations of the Krovetz stemmer online
