Hello to you all,

I would highly appreciate if someone would answer to the followings:

Is it possible to create a web-crawling program that could search on the internet for specific information and generate a summary out of the findings?
If it’s not possible, given today technology, how far are we from a that kind of achievement?

Thank you in advance.

Of course it is possible, though the summary generated is only as good as the corpus (web pages crawled).  Search through Google or Reddit and you will find some summarizing bots. A really nice online one is smmry. 

I suppose the choice of what to try depends on what programming language you are using, or if you are just looking for an API to an existing online tool.

Carl,
Thank you for your answer.

I would like a ‘smmry’ similar application, where the input should be a expressio (for example the name of a product) rather than a link. Than, given a certain nb of parameters, the app should web-crawl and get just a couple of relevant pages to summarise around that expression.

I would like to know if there is an open source application, but an API would work too.
In other words something similar to “smmry”, but adapted to a new application. 

Thank you again.

Enter into google: smmry algorithm

You will get a lot of links to various solutions, hopefully one of them will work for your needs.
