Web Scraping newbie!

Meteoroid

Hi everyone!

 

As a relative new-comer to Alteryx I am exploring some of the capabilities and one thing I would like to know more about is how to use Alteryx for web-scraping. I believe that some of you in this user group already use Alteryx for web-scraping and I was wondering if anyone would be willing to have a chat about it and/or demo what you have done?

 

Any help would be much appreciated!

 

Thanks,

 

Ricahrd.

Absolutely Richard,

Welcome to Webscraping! It's a fine art, what kind of websites are you looking to scrape?

Hi Samantha,

 

Thank you for getting back to me so quickly! At the moment I don't have a specific website in mind I'm really looking for some examples of what is possible and what other people are doing with the tool.

 

Thanks,

 

Richard.

Ok I'll try and find an example for you.

It's all about the websites really, as everyone is different, brush up your HTML, JSON and XML knowledge.

Then dig deeper with the developer tools within your browser. Here you will find all your gems.

Hi Richard,

 

It's great for building catalogues or mapping locations. You may also be able make use of internal data, such as extracting numbers from an active directory on your SharePoint to build a comprehensive phone directory on your mobile etc.

 

@joe_lipski  and the team at Javelin have an absolutely brilliant Webinar on it here: https://pages.alteryx.com/Javelin-Webinar-Series-Master.html

You can even download their examples!

 

Enjoy!

Hi Richard,

 

This is an example of where a website has JSON behind the scenes.

 

Check out the webinar series, if you haven’t already. It’s a great resource.

 

Enjoy,

 

Samantha

Thank you Samantha for the sample file and to Si for the link. I'll definitely check out the webinars!

 

Do either of you use web-scraping for senitment analysis at all?

We have done some twitter scraping for looking into text sentiment. Not actually got to that yet though. There is lots out there. Check this out if you haven't seen it yet. :)

Thanks for posting that article! Very interesting.

 

Richard, I've not webscaped to get my data, as reviews are prepared for me from another department in Excel format. I do however run sentiment analysis on them by using the following code in the R tool:

 

library(sentimentr)

sent <- sentiment_by(get_sentences(read.Alteryx("#1")))

write.Alteryx(sent, 1)

 

Please note, in order to make the script work, I have to use an older version of alteryx (2018.3) to find the library 'sentimentr'

(Check out the sentiment webinar too!)

 it may work in the 2019 releases, I will update mine and let you know!
