Snacktory

This is a small helper utility for people who don't want to write yet another java clone of Readability. In most cases, this is applied to articles, although it should work for any website to find its major area, extract its text, keywords, its main picture and more.

The resulting quality is high, even paper.li uses the core of snacktory. Also have a look into this article, it describes a news aggregator service which uses snacktory. But jetslide is no longer online.

Snacktory borrows some ideas and a lot of test cases from goose and jreadability:

Future

I would love to find one for maintenance and future development. Contact me if you have interests!

License

The software stands under Apache 2 License and comes with NO WARRANTY

Features

article text detection
get top image url(s)
get top video url
extraction of description, keywords, ...
good detection for none-english sites (German, Japanese, ...), snacktory does not depend on the word count in its text detection to support CJK languages
good charset detection
possible to do URL resolving, but caching is still possible after resolving
skipping some known filetypes
no http GET required to run the core tests

TODOs

only top text supported at the moment

Usage

Include the repo at: https://github.com/karussell/mvnrepo

Then add the dependency

<dependency>
   <groupId>de.jetwick</groupId>
   <artifactId>snacktory</artifactId>
   <version>1.1</version>
   <!-- or if you prefer the latest build <version>1.2-SNAPSHOT</version> -->
</dependency>

If you need this for Android be sure you read this issue.

Now you can use it as follows:

HtmlFetcher fetcher = new HtmlFetcher();
// set cache. e.g. take the map implementation from google collections:
// fetcher.setCache(new MapMaker().concurrencyLevel(20).maximumSize(count).
//    expireAfterWrite(minutes, TimeUnit.MINUTES).makeMap();

JResult res = fetcher.fetchAndExtract(articleUrl, resolveTimeout, true);
String text = res.getText(); 
String title = res.getTitle(); 
String imageUrl = res.getImageUrl();
