Coding open-ended questions using Deep Learning

In September 2015 we launched Thematic, which helps companies analyze customer feedback that they receive as part of surveys and qualitative studies. Thematic combines Deep Learning and NLP to automatically extract themes in thousands of comments and quantifies the importance of each theme, without the need of manual intervention or specialist setup knowledge. If you need to efficiently code open-ended questions, contact us for a free demo!

Getting girls into tech

posted Mar 1, 2015, 1:43 PM by Alyona Medelyan

My highlight from the beginning of 2015 has been running the Superheroes STEAM-ahead event, for which I raised $3000 using crowdfunding, attracted more than 300 school girls and their mums, and organised a successful career fair with 10 NZ companies and organisations. It was a huge undertaking but thanks to the STEAM-ahead team everything run smoothly, and the feedback from attendees was fantastic. I was invited to a blog post on the widely-read Public Address page about why I decided to run this event, and was surprised to receive a thank you letter from the Minister of Women's Affairs. Doing this in parallel with running Entopix and looking after my 2 year old daughter would not have been possible without the support of my mother.

The first NLP consultancy in NZ

posted Nov 3, 2013, 11:51 PM by Alyona Medelyan

After giving birth to our daughter, Maya, I have been looking for a more flexible and effective way of applying my skills. So I have decided to found an NLP consultancy named Entopix. The name comes from the art form "entopic graphomania", an automatic way of creating art pieces. I'm pleased that Entopix already has several customers and look forward to new adventures with this firm.

What happens to Kiwi CS graduates?

I recently gave a keynote at the NZ CSRSC 2013, a Computer Science PostGraduates conference organized by students for students, which happens every year at a different New Zealand university. 
For my talk, I run a survey to find out what happens to Kiwi CS graduates, which resulted in some interesting statistics. My slides and the summary of the results are summarized on my survey page.

Last week I spoke at Text Analytics World in Boston. The slides from my talk are now available on SlideShare. The talk introduced the area of keyword extraction, how a typical algorithm works and how it can be evaluated meaningfully, and also summarized a use case, where Pingar API has been installed on an Amazon cloud to extract keyphrases from nearly 2 million publications. Interview

posted Jul 23, 2012, 8:08 PM by Alyona Medelyan

Recently I was interviewed by Sean Golliher at about Pingar's technology. The interview is one of the first ones in their new innovation spotlight series and focuses on Pingar's keyword and entity extraction algorithms, applying these to unstructured data, including a Twitter-based experiment. I also talk about generating taxonomies on the fly and how Linked Data is used in this research to get great results.
