quanteda.classifiers: Text classification textmodel extensions for quanteda

To install this package, use the following, which also installs what the R keras package needs in order to run.

# devtools package required to install quanteda from Github 
devtools::install_github("quanteda/quanteda.classifiers") 

keras::install_keras(method = "conda")

This package contains two experimental methods that are built on top of the keras package. (The SVM models have been moved to quanteda.textmodels.)

| Classifier | Command | |---------------------------------------------------------------------|--------------------------| | Multilevel perceptron network | textmodel_mlp() | | Convolutional neural network + LSTM model fitted to word embeddings | textmodel_cnnlstmemb() |

| Corpus | Name | |------------------------------------------------------------------------------------------------------------------------------|--------------------------------| | Sentence-level corpus of UK party manifestos 1945–2019, partially annotated | data_corpus_manifestosentsUK | | Large Movie Review Dataset of 50,000 annotated highly polar movie reviews for training and testing, from Maas et. al. (2011) | data_corpus_LMRD |

See this (very preliminary!) performance comparison.
