事件 (英文)

事件主要依赖于:

1. tokenizer
2. entity
3. event

所以事件的英文样本处理将上面的主要数据预处理出来。

sample.json

[
  {
    "sentence": "He visited all his friends.",
    "tokens": ["He", "visited", "all", "his", "friends", "."],
    "pos-tag": ["PRP", "VBD", "PDT", "PRP$", "NNS", "."],

解析代码

如何运行以及相关依赖参考 其中的 "README.md"，但是在实际使用中还存在下面的问题。

相关环境

1. python3 >= 3.7
2. nltk
3. Standord CoreNlp

nltk

pip install nltk

但是在运行的时候会提示需要 "Resource punkt not found."。

自动安装:

import nltk
nltk.download('punkt')

手动安装:

nltk 说明如下:

Create a folder nltk_data, e.g. C:\nltk_data, or /usr/local/share/nltk_data, and subfolders chunkers, grammars, misc, sentiment, taggers, corpora, help, models, stemmers, tokenizers.

Download individual packages from http://nltk.org/nltk_data/ (see the “download” links). Unzip them to the appropriate subfolder. For example, the Brown Corpus, found at: https://raw.githubusercontent.com/nltk/nltk_data/gh-pages/packages/corpora/brown.zip is to be unzipped to nltk_data/corpora/brown.

具体操作:

1. 去 http://www.nltk.org/nltk_data/ 下载 punkt
2. 在 C:\nltk_data 或者 /usr/local/share/nltk_data 创建 tokenizers, 然后将上一步下载的punkt解压，放到 tokenizers 中。最后的文件目录如下: 你的路径/nltk_data/tokenizers/punkt

Standford CoreNLP 安装

pip install stanfordcorenlp

然后，下载资源包 http://nlp.stanford.edu/software/stanford-corenlp-full-2018-10-05.zip unzip stanford-corenlp-full-2018-10-05.zip

将资源包解压放到一个合适的目录下，

with StanfordCoreNLP('你的路径/stanford-corenlp-full-2018-10-05', memory='8g', timeout=60000) as nlp:

该资源包在试用的时候指定进入代码.
