Earthquake Start of a project to bring in information from a website with an Application Programming Interface (API). We are going to use a modified version of "Project: Fetching Current Weather Data" from "Automate the boring stuff with Python" by Al Sweigart What is going on below? We import libraries to dela with json, reuest from the server and the pandas library. In [1]: import json , requests import pandas as pd from pandas import json_normalize In this section we creating a string made up of the URL. Requesting the information from the site with the URL we created and pass back the information. Data comes from the US Geological survey  https://www.usgs.gov/about/about-us/who-we-are and one of their earthquake feeds. Then print out what was returned. In [2]: url = 'https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/all_hour.geojson' response = requests . get ( url ) response . raise_for_status () Now we need load the data which i

Social media network Analysis: Further visualisation

In a previous post (http://bit.ly/TAGS2GEPHI ) I look at moving data from a TAGS (https://tags.hawksey.info/) spreadsheet collecting tweets into a network visualisation tool (GEPHI) to plot a network of interactions based on how replied to whom. We left it at a graph like the one below with the thick the line the stronger/more replies there were.




Still going to use the same data but look at some of the other options to visualise these relationship. Tools like Gephi offer many ways to layout the plots

The one below is the ForceAtlas2 layout is good for showing groupings for this problem:
One I like because it is attractive and I feel shows the number of nodes and their interactions is the Fructerman Reingold (shown below)



One of the features of Gephi is you can add plug-ins; including new layouts. Two I am enjoying playing with is the Circular layout



Also the Dual circular layout - where you set two circles based on some criterian in this case number of interactions - the outer ring has the 20 highest scoring nodes and the central ring is the remaining nodes. 


What does it show? Possibly there is a lot of interactions between the highest scoring nodes.



Take home item I think is just play with the layouts and the tools.

The image to left show connections between tweeters using the hashtag #StarWars on the 30th December 2015 up to 6pm (GMT). Figure 2 shows the most active tweeters for this hashtag and the most influential based on Retweets and Mentions - the four greatest influencers are picked out in the video below, showing the map evolving (speed-up 20 times).   figure 2 To experiment with this a bit more  +The Royal Institution   has a long traditional of holding a series of Christmas Lectures  which are now televised, Dr Kevin Fong presented this years. I was curious about who the biggest influencers on twitter were for the hashtag #xmaslectures over the three days of the show. The three biggest influencers came out as  @Kevin_Fong @Ri_Sci

Social Visualisation using TAGS

Image
In a previous post I discussed using a twitter social analysis tool . In this post I am going to discuss another fantastic tool TAGS. Developed by Martin Hawksey ( @mhawksey ) this is a great free tool for visualising tweets; using a Google  Spreadsheet to be the  front end to link into Google Visualization API. I am not going to go into a description of how to set-up it here; I don't need to the best place to go for this is to follow the link here . In this post, I am mainly going through my (probably bit random) thoughts, an example and experiences with it. So the example was a twitter chat #caschat or #CASchat held on the 13th December 2016. The conversation is between teachers of computing as well as those who support or have an interest in supporting computing in schools.  Figure 1 I find the visualisation of twitter chats interesting; seeing the links between people, groups that form, but also seeing the way people engage.  So I set up the spread

Bibliographic Analysis Tools for Computing

Image
In this post, I am looking at a couple of ways to analyse biblographic data.  Starting with the simplest, Word Clouds but then an interesting tool VosViewer . All the data is taken from the University of Northampton's Research Repository - Nectar - for members of the academic Computing team.   Word Clouds The image above is based on data for all the listed publications for the computing team since 2011. It includes the authors, title, conference, etc; but no abstract. It takes quite a bit of editing and really all that is being shown is the Authors name for the most published authors and a few key terms. Provides a nice snap shot but is difficult to interpret. Taking this a bit further, looking at the titles of research outputs per year. Titles 2016 Titles 2015 Titles 2014 Title 2013 Title 2012 Title 2011 The interesting trend is the changing nature of the research in 2011 computer education comes out as a strong feature. In
