Filter Fine Tuning
- Filter Fine Tuning
Filter Definition Introduction
There are a few things that can help fine tune your filter immediately. Typically this involves setting up a Filter stage to exclude specific things that will remove articles from the filter news result.
Once you are at the bottom of the editor, click on AND to add a new Filter stage box. Once the new Filter stage opens up, click on the ANY OF THESE box in the upper left corner and it will switch to NONE OF THESE.
Anything you put in this Filter stage will be excluded from the results.
Fine Tuning Tips
A very useful entity for de-cluttering a filter is the Typically Excluded - All entity which is a rollup of topics that you normally do not want to see. Some examples are Accidents, Events, Company Filings and Stock Market Comments. Add this entity to the exclusion box to immediately remove a lot of noise from your Filter.

The first set of source categories to consider removing are the ones associated with blogs and social media sources.
The top category (Blogs & Social Media) will remove everything below it when it is included in the exclusion box.
The next set to consider are associated with company and industry publications. These can be enormously useful for certain types of use cases, but can also add noise if you are just looking for news.
- Company & Industry
Remember that you can use the lower level source categories to exclude that specific type. Tenders & RFPs for instance is almost always noise.
Articles published by Government, Academic, and/or University sources are covered by this set of source categories.
- Government & Organizations
Financial Research publications are covered by this source category.
- Investment & Financial Research
Specific Article Research
A more time consuming, but still effective way to fine tune a filter is to review articles that you do not want to have included in the filter individually, figure out the main characteristic that is associated with the article that can be used to exclude it from the filter news.
An easy item to review is the source associated with the article.
Since the source is visable in the Article Card at all time, you can review it quickly. If the source is something that can be explicitly excluded without changing the desired content in the filter, you can edit the filter and add the specific source to the exclusion box.
A source is always associated with a Contributor. In the Article Card, a source is shown consisting of two parts. The name before the / is a link to the Contributor. If you exclude the contributor, every source associated with that contributor will be removed. When you search for the source, the contributor will come up in the preview for the search as you type. If you want to exclude all sources from that contributor, select the contributor, not the full source name.
Look through the specific topics shown to see if there are any that can be exluded without changing the quality of your news results for the filter. If you find any that make sense to put into the exlusion box, edit your filter and add the topic to the box.
Sometimes a set of articles will be included in a filter that can be excluded by a specific text term. You can use Text Search to include or exclude specific text terms within a Filter definition. In some cases an included text term will have variations that need to be excluded. Put the variations into the exclusion box to remove them from the filter news result.
