Revealing a Network | sarahtiggy2

In my previous post, I finished with a very brief criticism of using AI to replace the traditional search using Google or similar.  The unreliability of AI is a popular topic at the moment – I read ‘Weapons of Math Destruction‘ by Cathy O’Neil not long after it was published, and there are now many more books and journal articles covering the subject.  The best way for me to explain my reservations is it terms of my own research.  I am trying to uncover the topics discussed by teacher bloggers, and to see if the things they talk about have changed over time.  To do this, I’ve harvested many…

Building a Web | sarahtiggy2

I’ve recently got involved in a very interesting project which is looking at ways in which research is recorded and stored, and how to build the academic profile of the author(s) for the benefit of them and the University in which they studies / researched / work.

All universities keep a repository of published work generated by students, researchers and staff.  On some university web sites, it’s easy to find and relatively easy to search; by author, title, faculty or year of publication.  However, that said there were two universities where I gave up trying to find their repository.  It’s…

Topic Modelling. It’s Hell. | sarahtiggy2

Topic Modelling. It’s Hell. | sarahtiggy2

Now I’m on the last chapter of my PhD (ok, so the other three still have some things I have to add, but hey-ho), it’s time to face up to the challenge of topic modelling.

The good thing about topic modelling is it’s a clustering problem: it assumes you know nothing about your data, and wants to find out what people have been writing about.  Actually, what topic modelling is, is the application of the Latent Dirichlet Application algorithm which assumes that if you know something about the words in the corpus, you can work out what the topics are.  It also assumes that all the documents…

Houston, We May Have A Problem…. | sarahtiggy2

Houston, We May Have A Problem…. | sarahtiggy2

I’ve been writing up my PhD.  This has been a very slow process, mainly because I’ve had to spend quite a bit of time going back through all my references, and re-planning the whole thing.  I bought post-it notes, and a tabletop flip chart (which is also like one massive post-it), and I’ve re-appraised everything.  As I write, I’m constantly adding more post-its as prompts of things I need to look up / do / add to the ‘discussion’ section at the end.

One of the things I decided I’d do was go back through my original data to make sure that I’d gathered everything I needed to, and to see if I…

Kicking Off The Actual Writing | sarahtiggy2

For the last two days, I’ve been up NORTH at a writing retreat, organised by the DEN, and held here.  I’ll add a link to my photos, but I’ll put this one here because it sums up the place perfectly!

I got loads of work done, as you can see.  I love technology, but sometimes you have to get the stationery out and do it the old-fashioned way.  Besides, who doesn’t love stationery, amiright?

The narrative…

The overall structure, minus the Introduction (which is next)

The Introduction

Starting the Literature Review, and some extra thoughts….

….and the Literature Review specifically…

University of Shanghai Datathon (March 2018) | sarahtiggy2

It’s taken me longer than usual to write this blog post.  This is partly because I’ve been very poorly since returning from China (the Doctor thinks I may have picked up a viral infection on the plane on the way home), and partly because the trip was very different from previous ones.  The purpose of this trip was to participate in a Datathon, with one day scheduled to have a look around Shanghai.  As it turned out, spending four days exploring data with other students was an absolute joy, and I was able to use many of my skills and the data processing tools I’d gathered which made the whole…
