将Stanford Parser纳入NLTK for Python
Stanford Parser是一个综合性的自然语言解析工具,可以无缝集成到NLTK中广泛流行的 Python 自然语言处理工具包。以下是如何实现此目的的详细指南:
Python 实现:
import os from nltk.parse import stanford # Set environment variables to specify jar paths os.environ['STANFORD_PARSER'] = '/path/to/standford/jars' os.environ['STANFORD_MODELS'] = '/path/to/standford/jars' # Initialize the parser parser = stanford.StanfordParser(model_path="/location/of/englishPCFG.ser.gz") # Parse sentences sentences = parser.raw_parse_sents(("Hello, My name is Melroy.", "What is your name?")) print(sentences) # GUI visualization for line in sentences: for sentence in line: sentence.draw()
示例输出:
[Tree('ROOT', [Tree('S', [Tree('INTJ', [Tree('UH', ['Hello'])]), Tree(',', [',']), Tree('NP', [Tree('PRP$', ['My']), Tree('NN', ['name'])]), Tree('VP', [Tree('VBZ', ['is']), Tree('ADJP', [Tree('JJ', ['Melroy'])])]), Tree('.', ['.'])])]), Tree('ROOT', [Tree('SBARQ', [Tree('WHNP', [Tree('WP', ['What'])]), Tree('SQ', [Tree('VBZ', ['is']), Tree('NP', [Tree('PRP$', ['your']), Tree('NN', ['name'])])]), Tree('.', ['?'])])])}

安装过程:
选项 1:使用 NLTK 下载器
选项 2:手动安装
