问题 I have error when using Apache OpenNLP with Solr (ver. 7.3.0) in Cloud mode. When I add field type to managed-schema using open nlp like this: <fieldType name="text_opennlp" class="solr.TextField"> <analyzer> <tokenizer class="solr.OpenNLPTokenizerFactory" sentenceModel="opennlp/en-sent.bin" tokenizerModel="opennlp/en-token.bin" /> </analyzer> </fieldType> <field name="content" type="text_opennlp" indexed="true" termOffsets="true" stored="true" termPayloads="true" termPositions="true"

问题 I tried to train a custom model for NER using openNlp. When I pass a sentence to predict the Entity, It just picks the first word of the sentence. Don't know where I am going wrong,. Please find the training model code below, public class OpenNLPNER { public static void main(String[] args) { train("en", "technology", "D:\\dl4j-examples-master\\dl4j-examples-master\\dl4j-examples\\src\\main\\java\\opennlpExamples\\src\\main\\resources\\technology.train", "D:\\dl4j-examples-master\\dl4j

问题 I have a question concerning OpenNLP. I am looking for Spanish sentence detection and tokenization models that run with OpenNLP version 1.5.3. So far, I only found a pos tagging model that works with this version (https://github.com/utcompling/OpenNLP-Models/tree/master/models) Additionally to the Spanish models, I need to use also English, French and Italian models in one java project. So far, I could find all models (sentence detection, tokenization and pos tagging) for every language,

问题 I am trying to get entities from a query. I have a custom NameFinder model. Queries are like this. result for roll number 1304510020. result for roll-number 1304510020. result for rollnumber 1304510020. result of rollnumber 1304510020. result of roll number 1304510020. result of roll-number 1304510020. roll number 1304510020 result. rollnumber 1304510020 result. roll-number 1304510020 result. show result of roll number 1304510020. show result of rollnumber 1304510020. show result of roll

问题 I am using opennlp training api as shown below: Blockquote opennlp DoccatTrainer -model en-doccat.bin -lang en -data Task_notes_1new.train -encoding ISO-8859-1 Blockquote this api creates a model named en-doccat.bin from the training dataset Task_notes_1new.train. while training with the above command getting following error: Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at opennlp.maxent.GISTrainer.trainModel(GISTrainer.java:301) at opennlp.maxent.GIS.trainModel(GIS

问题 I have tried doing POS tagging using openNLP POS Models on a normal Java application. Now I would like to implement it on Android platform. I am not sure what is the Android requirement or restrictions as I am not able to read the models (binary file) and execute the POS tagging properly. I tried getting the .bin file from external storage as well as putting it in an external libraries but still it couldn't work. These are my codes: InputStream modelIn = null; POSModel model = null; String

问题 I am trying to use the Custom Feature generation of OpenNLP for Named Finder API. http://opennlp.apache.org/documentation/1.5.3/manual/opennlp.html I went through the documentation but I was not able to understand how to specify the different features. It just says: AdaptiveFeatureGenerator featureGenerator = new CachedFeatureGenerator( new AdaptiveFeatureGenerator[]{ new WindowFeatureGenerator(new TokenFeatureGenerator(), 2, 2), new WindowFeatureGenerator(new TokenClassFeatureGenerator(true)

问题 I am analysing a few million emails. My aim is to be able to classify then into groups. Groups could be e.g.: Delivery problems (slow delivery, slow handling before dispatch, incorrect availability information, etc.) Customer service problems (slow email response time, impolite response, etc.) Return issues (slow handling of return request, lack of helpfulness from the customer service, etc.) Pricing complaint (hidden fee's discovered, etc.) In order to perform this classification, I need a

问题 My current understanding is that it's possible to extract entities from a text document using toolkits such as OpenNLP, Stanford NLP. However, is there a way to find relationships between these entities? For example consider the following text : "As some of you may know, I spent last week at CERN, the European high-energy physics laboratory where the famous Higgs boson was discovered last July. Every time I go to CERN I feel a deep sense of reverence. Apart from quick visits over the years, I

问题 what is the meaning of cut-off and iteration for training in OpenNLP? or for that matter natural language processing. I need just a layman explanation of these terms. As far as I think, iteration is the number of times the algorithm is repeated and cut off is a value such that if a text has value above this cut off for some specific category it will get mapped to that category. Am I right? 回答1: Correct, the term iteration refers to the general notion of iterative algorithms , where one sets
