Earlier quoted context omitted.

Using natural language processing and supervised learning, it automatically tagged news with 9 categories.

That's really interesting. Will you open-source the NLP algorithm?

I am planning to open source it in several months. (Our codes have not been well-commented and well-structured yet...

Our implementation and algorithm detail is followings.

Its categorizing process is written in Python.

Using nltk, it makes corpus with TFIDF model from HN topics and comments. And it generates classifiers from this corpus with SVM algorithm using scipy and numpy.

FYI, its web interface is written in Clojure and ClojureScript.

Very nice. How you determine categories?

Using natural language processing and supervised learning, it automatically tagged news with 9 categories.

Should http://news.ycombinator.com/item?id=7183076 be categorized as Web Technology then?

It would be useful to have a category for startups. I find that's the content I most look for here.

Looks awful on mobile would be great if you could make it responsive.

Yes. I will support responsive design in the near future.

This is super useful! I have been forcing myself off HN lately. One thing that I miss the most due to this is the SHOW:HNs of really cool products and hacks that hit the front page. This gives me a great month-to-month access to those great stories at one place. Bookmarked!

I find the font uncomfortably small - make the styling more like HN?

This is interesting. But it's not quite sync with the News on the first page. What do you sort by? If it works well, I'd like to use it.

Thanks.

It crawls HN topics every one hour. So news in our application would delay up to one hour.

Awesome! Too bad jokes category does not have a lot of content, pity.

I think something needs to be done about that.

But, humour is almost universally subjective. There are some aspects of Obama-Care that I thought were highly amusing, especially the "500 million lines of code" gag.

Here is a very serious article about the C programming language.
