Stanford-OpenIE-Spider

Extract Information from WebCorpus using Stanford Open Information Extraction.

About Stanford IE

Open information extraction (open IE) refers to the extraction of structured relation triples from plain text, such that the schema for these relations does not need to be specified in advance. For example, Barack Obama was born in Hawaii would create a triple (Barack Obama; was born in; Hawaii), corresponding to the open domain relation "was born in". This software is a Java implementation of an open IE system as described in the paper:

Gabor Angeli, Melvin Johnson Premkumar, and Christopher D. Manning. Leveraging Linguistic Structure For Open Domain Information Extraction. In Proceedings of the Association of Computational Linguistics (ACL), 2015. The system first splits each sentence into a set of entailed clauses. Each clause is then maximally shortened, producing a set of entailed shorter sentence fragments. These fragments are then segmented into OpenIE triples, and output by the system.

About Open Information Extraction(http://openie.allenai.org/)

This is a web service that implement information extraction feature from web corpus using Stanford IE. We can search the relation in the web from this website.

Usage

First of all, please make sure python is installed.

python --version

Install scrapy.

sudo pip install scrapy

You can also see the offical document from here. https://doc.scrapy.org/en/latest/intro/install.html

Install beautifulsoup4.

sudo pip install beautifulsoup4

Copy code into local.

git clone git@github.com:liaoziyang/Stanford-OpenIE-Spider.git
cd Stanford-OpenIE-Spider

Argument

Require at least one parameter below, using -a option.

And you can write the result into file by using -o option.

Example

Extract the information "What kills bacteria?" from the web corpus.

scrapy runspider -a rel=kills -a args2=bacteria openie_spider.py -o result.json

And the result in result.json is like: key is the string representation of the result and the value is the frequency of the result appeared in the web corpus.
