In yesterday’s post, we paid tribute to several speakers, including Christian Moen and Gaute Lambertsen, software engineers at Atlika, a Japanese corporation providing innovative products and services within search. The speakers are pioneers in leveraging language to enhance the overall user experience. The elevation of search in recent years – particular open-source search – to enhance experience is one of the most noteworthy developments in the world of digital commerce. And it is well exemplified by the persistent presence of luminaries in the field. This year’s Revolution event features two regulars on the speaker circuit – Stephen Murtagh, Data Scientist at Etsy.com and Mikhail Khludnev, Principal Engineer at Grid Dynamics – who are not only innovators in the field but whose organizations are known for eCommerce and the user experience. Khludnev spoke at sister events Lucene Eurocon 2011 and ApacheCon 2012. A clip is included at the bottom of this post. Murtagh has spoken previously at an Advancing the Sciences of Limnology and Oceanography conference, and the SCOR working group.

As data scientist at Etsy, Murtagh is focused on building data-driven products. Since its launch in 2005, the company has distinguished itself as an online marketplace with a commitment for developing new tools and services that enhance the experience for both seller and buyer. Today, Etsy serves more than 850,000 active shops, representing 200 countries, with 42 million monthly unique visitors, and 1.5 billion monthly page views. The enormous volume of data that the company generates provides a unique opportunity to build data-driven projects, and search has played a role. He’ll present the session entitled Beyond TF-IDF: Why, What and How.

At GridDynamics, Khludnev works with the eCommerce Search Platform team. Among other things, the company provides custom technology platforms for large-scale eCommerce operations leveraging open source and cloud technologies. This year’s session looks at the topic of Concept Search for eCommerce and Solr. This talk describes the company’s experience in eCommerce Search: challenges which they have faced and the chosen approaches. We believe that this session like several others below, can serve as foundational “courses” at this year’s event, specifically for those interested in eCommerce and the user experience.
