Generating Blog Keyword Tags and Tagxedo Clouds with Yahoo Pipes

Standard

As I’ve been adding blog posts here I’ve noticed that the keyword tags are getting into a mess. So I’ve been thinking about what I could do to sort them out, either by getting the computer to do the tagging for me, or provide another way of presenting relevant keywords about specific blog posts to anyone who visits my blog.

As a first attempt (1), I decided to use Yahoo pipes and simply feed in the RSS feed of my blog, pull out keywords from each blog post and then create another RSS feed to be used anywhere. Visitors can view keywords for the last 10 blog posts, as I couldn’t get Yahoo pipes to go beyond 10. They can also click on a link to the blog post. The words/phrases pulled out aren’t perfect (as with any automated word extraction), but I think you get a good feel for the blog posts from them.

(NB: Click on ‘List’ to see the keywords and use the link back to the blog.)

At the same time, I was thinking about whether I could use something like a tag cloud generator to do what I wanted a bit more creatively. Having a look at Tagxedo, I realised that if you use the URL function on the home page to create a cloud you could actually build the url yourself. So, I created a second pipe (2) that presented the same keywords, but also provides a clickable link that feeds through to Tagxedo and creates individual tag clouds for each entry.

(NB: Click on ‘List’ to see the keywords and use the link to generate the cloud.)

Ultimately, I did want to combine the two pipes, but I couldn’t get Yahoo pipes to create valid links to 2 places in the same RSS item.

I would have also liked the Tagxedo cloud to display in the RSS feed, but at the moment the link just creates a cloud from the RSS.

Hopefully there is a way to achieve both of these things, but as a first attempt I think they both work quite well, even if the RSS feeds/presentation do need a bit of tidying up.

The results of the embedded pipes can be found on my test site here. Links to the source code of the pipe can be found in (1) and (2) above. I’ve also added the RSS to the blog on the right hand side to see how people get on with it. The feed is labelled ‘Term Tags’.
