Personally, I don't really see a reason for the chart. It would be nice to have a way to disable it.

feconroses10• 11 years ago

Great idea! We will add a way to disable the chart today! Will let you know when its ready

feconroses10• 11 years ago

Done! We added a button to hide / show the chart. It will remember your settings for future sessions.

You reinvented subreddits.

paxcoder• 11 years ago

No, they trained an automatic categorizer and built a filtering front-end.

keslag• 11 years ago

Subreddits are a way to form communities centred around a theme or concept; this is a way to filter out the noise that you're not interested in. Very very different.

This would be fantastic if there was just a filter to hide all of the political posts here yet still show everything else.

feconroses10• 11 years ago

Fantastic idea! Will implement this today too! Will let you know when its ready :)

res0nat0r2• 11 years ago

Awesome :]

I would like the opposite. So many things wrong, so much injustice in the world, so many with power and privilege closing their eyes to it. Cognitive dissonance may be great for individual well-being, but it sucks for humanity.

Any ideas on how to make My Hacker News better? Please let us know!

onion2k• 11 years ago

I found that I disagree with about 25% of the categorisations.

feconroses10• 11 years ago

We agree with you that there is room for improvement. We can make it more accurate by adding more training samples to the MonkeyLearn classifier. We plan to keep working on this to make it better.

It's reassuring to see that HN has had ten design articles... ever :)

eudox• 11 years ago

It has a limited time range.

Would it be possible to add RSS feeds for each category page? I currently read HN via an RSS reader and filter out any articles with less than 10 points. I would much rather filter out categories I don't care too much about.

feconroses10• 11 years ago

Cool idea! We will work on adding RSS feeds for each category page. Probably between today and tomorrow we will have it ready. Will let you know :)

feconroses10• 11 years ago

Done! We added RSS feeds for each category. You can see the different feeds at the right of each category. For example programming feed: http://hackernews.demos.monkeylearn.com/feed.xml?c=programmi...

One category has a typo: 'entertaiment'

feconroses10• 11 years ago

Thanks! Will fix it!

feconroses10• 11 years ago

fixed

primaryobjects• 11 years ago

Just curious, why did you decide to use a supervised learning approach for this? You're hard-coding the categories in this manner.

You could try using clustering instead (K-means) to group the posts together into their own categories. This is similar to a "trending topics" approach, where the categories could change each day.

What is the X-axis in the graph?

feconroses10• 11 years ago

The X-axis is the hour of the day. The graph is to see which categories are the most popular today, according to the hour published. We have added this legend to the graph.

I'd like to be able to select multiple categories (for example, "programming" AND "science" AND "security").

Also, there's no obvious way to indicate an incorrect categorization (like the one about Ripple being fined; that fits better in "business" or even "politics", yet is the top result in "science" right now). If it's machine-learning-based, it's probably much more useful to be continuously learning based on user feedback rather than generating a model and sticking with it forever (especially when the model is visibly inaccurate in some circumstances).

Also, the job postings should probably be a separate category instead of being lumped into business.

what an amazing way to pitch your service! Big thumbs up!
