Since PositivePress uses RSS feeds as input, I decided to do a quick video showing you how to use Yahoo Pipes to filter results from your RSS feed to make sure that you are only archiving and reporting on the most relevant results. This video shows you how to take a list of feeds from a CSV file, fetch the results, and filter them for a set of keywords. The end result is fed into PositivePress and a new report is generated from the filtered results.
If you haven’t already watched the rest of the Yahoo Pipes Video series, you might benefit from watching these other videos first. They provide a little more background on the concepts used in this Yahoo Pipe.
It’s been a while since I’ve posted a 2 minute Yahoo Pipes video, but I had an opportunity to do a guest post on the Yahoo Developer Network blog (yay!), and I thought that a 2 minute screencast would be the best way to demonstrate my pipe.
This 2 minute demo takes a series of keywords from a CSV file and uses Yahoo Pipes to run each keyword through various searches. This technique can be very powerful when you search multiple services, but I’ve simplified the process to make it easier to understand the fundamentals of the technique by running the list of keywords only through Twitter search.
This 2 minute Yahoo Pipes demos shows how to filter by date using the filter module combined with the date builder module to find all of the posts in the past 2 days from our feeds. If you haven’t already watched the 2 Minute Yahoo Pipes Introductory Demo, I strongly suggest that you watch it. This demo builds on the basic structure developed in the introductory demo with the same feeds from ReadWriteWeb and GigaOM that we used in the original demo.
We’ve talked about many different uses for Yahoo Pipes in previous 2 minute Yahoo Pipes demos, but you can also use most existing Yahoo Pipes within other pipes. In this demo, we’ll use a couple of pipes I’ve previously created as the input into a new Yahoo Pipe, and we’ll introduce the union operator as a way to pull several inputs together.
This video shows how to get input from a list of items in a CSV file, and it introduces the loop module. A CSV file is a great choice when you want to fetch a bunch of feeds and change them frequently without having to update your pipe. If you haven’t already watched the 2 Minute Yahoo Pipes Introductory Demo, I strongly suggest that you watch it. This demo builds on the basic structure developed in the introductory demo. The CSV file I’m using also contains the same feeds from ReadWriteWeb and GigaOM that we used in the original demo plus a few others.
If you have been wanting to create Yahoo Pipes, but weren’t quite sure where to start when faced with the blank page on a new Yahoo Pipe, I created a very simple demo to get you started. This Yahoo Pipes demo will help you get started with Yahoo Pipes and show you what you need to know to create a basic Pipe. We use filtering for this example, since Yahoo Pipes is great at taking feeds and filtering to display only the posts that match (or exclude) certain keywords. The demo covers taking multiple feeds as inputs, filtering on keywords, sorting, and using the debugger to analyze the elements of your source feeds and your output. After watching this demo, you should be able to create a basic Yahoo Pipe and use it to filter to include or exclude items that match certain keywords.
Yahoo Pipes Training
I also wanted to take this opportunity to announce that I will begin conducting Yahoo Pipes training for organizations. These 2 hour classes will cover the basics of building Yahoo Pipes and provide some custom content if needed to help meet the specific needs of your organization.
