Ctrl-News is powered by the “ctrl semantic engine“, ctrl-news is an online service that can be viewed as a “customized news homepage” for its users.

The ctrl-News homepage allows users to filter news semantically and topically, depending on their preferred and customized subject(s) of interest. Moreover, users can see an automatically-generated summary, as well as the entities and the key topics (disambiguated) for every news article received.

Who is behind ctrl-News?

ctrl-News is not only powered by the ctrl semantic engine, it was actually created by the same team who created ctrl to show ONE possible application that can be built on top of their semantic engine ctrl – the first product of the Research and Development group at PRAGMATECH.

 

How to register to this service?

The following error appeared “Subject of interest X has 44 words. It should have a minimum of 80 words” why is that?

ctrl-News relies on heavy semantic analysis of the text that comprises your subjects of interest in order to find the most related articles from everyday’s news. Knowing that, it is recommended to enter at least 80 words in each subject of interest to ensure best results.

Concerning retrieved articles, what retrieval accuracy should I expect from ctrl-news?

ctrl-News results are all automatically generated by the ctrl semantic engine, and, therefore, rely totally on the topical similarity between the entered subject of interest and the processed news articles. Therefore, in some cases, the returned articles do not match the user’s expectations – although we are certain that our accuracy in determining topic relevancy is extremely high. Please use the feedback functionality to report such cases helping us accordingly to improve the existing system.

 

How does ctrl-News decide on the similarity between articles and my subject of interest?

ctrl-News uses the ctrl semantic engine to process each subject of interest you enter. It then tries to find the most related articles from the processed news articles based on their topical similarity (in addiction to other subtle document attributes). By topical similarity we mean that the main topics of the subject of interest are similar to the ones of these articles. Accordingly, you might receive articles that are discussing the same topic with different ‘players’ (location, people, etc). Please use the feedback functionality to report the cases where you didn’t find the results relevant.

 

How far back does ctrl-news retain my retrieved results?

Currently 2 weeks. However, we may prolong this period in the future if enough users deemed this necessary.

 

What is meant by entities?

The Entities section displays all the ‘names’ of things that ctrl automatically identified in the text along with their specific type and definition. These include names of Agencies, Associations, Awards, Brands, Companies, Consumer products, Diseases, Educational institutes, Events, Medicines, Organizations, Outlets, People, Political events, Political group, Publication, Software systems, Teams, Tournaments, Websites, gadgets.

 

What languages does ctrl-News support?

Currently, ctrl-news only supports the English language. However, with relatively minimal effort, its semantic engine can virtually support any language.

 

Can I advertise on ctrl-News?

Pragmatech’s ctrl team is currently working on another application that can showcase their ctrl engine’s superiority in semantic analysis through semantic push of ads on ctrl-News. This functionality will be free of charge and very easy to use. Stay posted!!!

On the bottom part of homepage (when not logged in) a list of news sources appears in a flash animation. Also, you may find the list in the archive section. However, this list contains more detailed information of the RSS feeds ctrl-news fetches from each of these news sources.
