Question

I am having an error in the following java method.

pipeline <- javaMethod('createCoreNLP', 'edu.stanford.nlp.pipeline.StanfordCoreNLP', 'en')

Error in javaMethod("createCoreNLP", "edu.stanford.nlp.pipeline.StanfordCoreNLP", :
could not find function "javaMethod"

Here is my codes:

Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jdk-18.0.1.1')
library(rJava)

library(coreNLP)
options( java.parameters = "-Xmx6g" )

#Set up the environment for Java
#Init Java
#.jinit(classpath = c(file.path(Sys.getenv('HOME'), '/Downloads/stanford-corenlp-full-2018-02-27/stanford-corenlp-3.9.1.jar'), file.path(Sys.getenv('HOME'), '/Downloads/stanford-corenlp-full-2018-02-27/slf4j-simple.jar'), file.path(Sys.getenv('HOME'), '/Downloads/stanford-corenlp-full-2018-02-27/slf4j-api.jar')), boundaries = '- Xmx5120m')
.jinit(classpath = c(file.path(Sys.getenv('HOME'), '~/IS 688/stanford-corenlp-4.4.0/stanford-corenlp-4.4.0.jar'), file.path(Sys.getenv('HOME'), '~/IS 688/stanford-corenlp-4.4.0/slf4j-simple.jar'), file.path(Sys.getenv('HOME'), '~/IS 688/stanford-corenlp-4.4.0/ slf4j-api.jar')), boundaries = '- Xmx6g')

#initCoreNLP("~/IS688/stanford-corenlp-4.4.0/",mem = "6g",parameterFile="~/IS688/stanford-corenlp-4.4.0/corenlp.properties")

#Create thesentiment analyzer
sentimentAnalyzer <- function(doc){

#Create an empty list
sentimentList <- list()

#Create a CoreNLP pipeline
pipeline <- javaMethod('createCoreNLP', 'edu.stanford.nlp.pipeline.StanfordCoreNLP', 'en')

#Annotate the document
annotation <- javaMethod('process', 'edu.stanford.nlp.util.CoreMap', pipeline, doc)

#Get the sentiment of the first sentence
sentiment <- javaMethod('get', 'edu.stanford.nlp.ling.CoreAnnotations$SentimentClass', annotation$get('sentences')[1])

#Add the sentiment to the list
sentimentList$sentiment <- sentiment

#Get the tokens of the first sentence
tokens <- javaMethod('get', 'edu.stanford.nlp.ling.CoreAnnotations$TokensAnnotation', annotation$get('sentences')[1])

#Add the tokens to the list
sentimentList$tokens <- tokens

#Return the list
return(sentimentList)
}
