Just out of curiousity, where's memory blowing out? Could you send us a stack trace? Our naive Bayes isn't quite that scalable, I'm afraid. We use sparse...
Hi One application I am working on have nearly 42000 classes. I am using TraideNiaveBayes classifier of lingpipe, My system is giving me "Out of Memory Error"...
1200 classes are a bit much for something like language model classifiers. LingPipe's implementation scales linearly in the number of classes at run time. ...
... Actually my application have nearly 1200 different classes. And identifying these feature manually is not feasible. So I am looking for any heuristic...
It's different for the two classes. Just a terminological note -- neither of these are what people call "discriminative classifiers". Our discimrinative...
No, none of the tutorials explain how to do this. The way to do it is to use the BioTagChunkCodec class. Make sure to plug in the same tokenizer factory you...
What I have is, for each sentence: Tagging<String> object that I get using HmmDecoder (POS tagging tutorial on LingPipe). And then I send this sentence to...
HI I am using TfIdfClassifierTrainer<CharSequence> and DynamicLMClassifier<NGramProcessLM> for a text categorization task (multiple classes). I am able to...
I agree that the evals are confusing, and any suggestions on improving doc, etc., would be greatly appreciated. We are providing industry-standard evals, but...
I'm not sure how you're trying to get this to work, so I'm not sure how to help. I'm assuming you just want the CoNLL-style output you showed. Once you have...
I have been trying to re-tokenize, but does not work efficiently. I mess up the token order in the sentence and some stopwords come up in named entities. What...
Dear All, I have a question concerning an evaluator of any chunker. One of the evaluation criteria of the FIRST-BEST EVAL is the total. This total as I...
There are both traditional and simplified Chinese segmenters available in LingPipe itself. We show how to adapt these into chunkers in the tutorial: ...
You need to implement the TokenizerFactory interface which in turn will require implementation of the Tokenizer interface. Start with the Javadoc for...

hi, I found a simple chinese segmenter in http://code.google.com/p/ik-analyzer/downloads/list the usage is simple, just like the following code: IKSegmentation...
You should be able to do what Breck suggests and re-tokenize. It's relatively straightforward with first-best, but much more complex if you need to merge...
... The typical syntactic category for a named entity is Noun Phrase(NP) or Proper Noun Phrase (PNP) depending on how you want to organize the phrases. You...
Hello, How do I get Part-of-Speech tags and named entity tags at the same time (for biomedical text)? What is happening is POS tagging using MedPost is...
Yes it is! Making it a nice companion to Lingpipe. Usually I use this tool for simple language models: http://www.speech.cs.cmu.edu/tools/lmtool-new.html It is...
I would love to train a language model in Lingpipe to use in speech recognition engine like CMU's Sphinx4. Any thoughts on exporting a Language Model from...
Yes. You can use LingPipe's com.aliasi.util.Compilable interface to compile the model to a file or Java's java.io.Serializable interface to serialize the...
Hi, As a part of my academic research project, I am trying to build an application wherein I will have a set of urls retrieved from the web. The task is...
While browsing around the Lingpipe site a couple weeks ago, I recall seeing a reference to a contrib module or something that was an interface for training...
It's about normalization of probability estimates. For the process model, SUM_{strings s of length N} prob(s) = 1. For the boundary model, SUM_{strings s}...
