Freebase中所有标题/主题标题的文本文件 [英] text file of all titles / topic titles in Freebase

问题描述

我需要一个文本文件来包含.txt文件中每个项目的每个标题/标题。我这样做，或者如果我已经下载了一个freebase rdf转储这样做，如果可能，我还需要一个单独的文本文件，每个主题的/项目的描述在一个单一的每行描述一下。

我该怎么做？

有人可以帮我从Freebase的rdf转储文件中提取这两个文件。

感谢您的帮助！

解决方案在谓词/属性 ns：type.object.name 上过滤RDF转储。如果您只想要特定的语言，还可以按照该语言进行过滤，例如编辑：我错过了关于描述所需的第二部分以及。这里有一个三部分的正则表达式可以帮助你：
$ b

1. 英文名字


2. 英文说明


3. 类型/ commmon / topic









  zegrep $'\ tns：（（（type \\.object\\。名称| common\\.topic\\.description）\t * @中文）| type\\.object\\.type\tns：common\\.topic） \\'$'freebase-rdf-2013-06-30-00-00.gz | gzip> freebase-rdf-2013-06-30-00-00-names-descriptions.gz 
  

看来有一个性能问题，我不得不看看。整个文件的一个简单的grep需要我的笔记本电脑〜11分钟，但这已经运行了几次。我将不得不稍后再看...


I need a text file to contain every title / title of each topic / title of each item in a .txt file each on its own line.

How can I do this or make this if I have already downloaded a freebase rdf dump?

If possible, I also need a separate text file with each topic's / item's description on a single line each description on its own line.

How can I do that?

I would greatly appreciate it if someone could help me make either of these files from a Freebase rdf dump.

Thanks in Advance!

解决方案

Filter the RDF dump on the predicate/property ns:type.object.name. If you only want a particular language, also filter by that language e.g. @en.

EDIT: I missed the second part about descriptions being desired as well. Here's a three part regex which will get you all the lines with:

1. English names
2. English descriptions
3. a type of /commmon/topic

Combining the three is left as an exercise for the reader.

zegrep $'\tns:(((type\\.object\\.name|common\\.topic\\.description)\t.*@en)|type\\.object\\.type\tns:common\\.topic)\\.$' freebase-rdf-2013-06-30-00-00.gz | gzip > freebase-rdf-2013-06-30-00-00-names-descriptions.gz

It seems to have a performance issue that I'll have to look at. A simple grep of the entire file takes ~11 min on my laptop, but this has been running several times that. I'll have to look at it later though...
