In this post, we’ll explore how we built a Knime project to fetch the latest news from top media outlets using their RSS feeds. This workflow allows us to collect real-time news updates and present them in a user-friendly interface.

Connecting to RSS Feeds
The first step of our workflow involves connecting to the RSS feeds of major media outlets. We achieve this by using Knime's RSS Feed Reader node, which pulls in live updates from multiple sources.
Once we’ve gathered the news, the workflow concatenates the results into a single table, providing a unified view of the news headlines. This is then passed to a dashboard component for further interaction and visualization.
Creating an Interactive Dashboard
Inside the dashboard component, we present the news data in two key ways. First, the results are shown in a table with clickable hyperlinks, allowing users to quickly access the full news articles. Additionally, we include a slicer based on media outlets, enabling users to filter the news by source.
Visualizing Word Frequencies with a Word Cloud
In the second part of the dashboard, we introduce a word cloud that highlights the most common terms across the news articles. Before generating the word cloud, the workflow processes the data to clean up irrelevant words and structures it into a "bag of words." We then calculate term frequencies, visualizing the most important or trending keywords in the news.
This not only helps users quickly identify popular topics but also adds an engaging visual element to the dashboard.
One-Click Access to the Latest News
The final result is an intuitive, streamlined interface where you can instantly get the latest headlines from top outlets with just a single click. With Knime's browser capabilities, you can also read the articles directly within the platform, eliminating the need to switch between applications.
Conclusion
With this Knime workflow, staying updated on breaking news has never been easier. The combination of real-time data fetching, interactive filtering, and keyword visualization offers a powerful tool for anyone needing instant access to the latest media coverage
