安裝

不需要安裝，直接從github上download下來就行

使用方法

java -jar BerkeleyParser-1.7.jar -gr <grammar>

<grammar>

然后就啟動了，你輸入一句話，它會返回這句話的parse結果。

java -jar BerkeleyParser-1.7.jar

-render                       Write rendered tree to image file. (Default: false)
-maxLength                    Maximum sentence length (Default = 200).
-binarize                     Output binarized trees. (Default: false)
-variational                  Use variational rule score approximation instead of max-rule (Default: false)
-useGoldPOS                   Read data in CoNLL format, including gold part of speech tags.
-dumpPosteriors               Dump max-rule posteriors to disk.
-ec_format                    Use Eugene Charniak's input and output format.
-nThreads                     Parse in parallel using n threads (Default: 1).
-modelScore                   Output effective model score (max rule score for max rule parser) (Default: false)
-keepFunctionLabels           Retain predicted function labels. Model must have been trained with function labels. (Default: false)
-nGrammars                    Use a product model based on that many grammars
-chinese                      Enable some Chinese specific features in the lexicon.
-scores                       Output inside scores (only for binarized viterbi trees). (Default: false)
-tokenize                     Tokenize input first. (Default: false=text is already tokenized)
-substates                    Output subcategories (only for binarized viterbi trees). (Default: false)
-outputFile                   Store output in this file instead of printing it to STDOUT.
-confidence                   Output confidence measure, i.e. likelihood of tree given words: P(T|w) (Default: false)
-gr                           Grammarfile (Required)
 [required]
-accurate                     Set thresholds for accuracy. (Default: set thresholds for efficiency)
-inputFile                    Read input from this file instead of reading it from STDIN.
-kbest                        Output the k best parse max-rule trees (Default: 1).
-tree_likelihood              Output joint likelihood of tree and words: P(t,w) (Default: false)
-viterbi                      Compute viterbi derivation instead of max-rule tree (Default: max-rule)
-sentence_likelihood          Output sentence likelihood, i.e. summing out all parse trees: P(w) (Default: false)
-h                            help message
