Hugo Zaragoza (bio)

_MG_4427

I am founding Director of Websays, a pioneering start-up in sentiment analysis and opinion analytics.

My research has always been at the frontier of machine learning, natural language processing and search, pushing the boundaries of search engines and text mining technologies. I have worked in applied research for over 10 years both at Yahoo! Research, where I led the Natural Language Retrieval group, and Microsoft Research, where I worked in the Machine Learning group. Some of my work at Yahoo! and Microsoft is in production and used by millions of people today. I am the author of around 50 scientific articles and 20 patents, and regularly consult for companies and give talks and lectures.

Some ideas stick to my head and simply won’t go away.

Sometimes I can turn them into a demo, a paper or a proposal of some kind…

But other times they are just too rough, too vague, too weird…

I write these here so I can rest!

Extended BIO

Hugo has been a researcher at the frontier of Natural Language Processing, Machine Learning and Search (orInformation Retrieval) since 1997.

Hugo Zaragoza is the founding CEO of Websays since 2010, a company dedicated to the analysis of conversations and opinions online.

At Yahoo! Research Barcelona, Hugo led the Natural Language Retrieval group from 2006 to 2011. Research dealt mainly with applications of natural language processing to web search applications, in particular relevance ranking and algorithms for search over large and heavily annotated collections (our version of “semantic search”). Some examples of the work of his group can be seen in the public demos Correlator, Quest and Time Explorer.

From 2001 to 2006 Hugo worked at Microsoft Research (Cambridge, UK) with Stephen Robertson, where he explored applications of machine learning (ML) and natural language processing (NLP) for information retrieval (IR), in particular for corporate and web search, but also on document classification, expert finding, relevance feedback and dialogue generation for games. While at Microsoft Research Hugo also spent a considerable amount of time collaborating with Microsoft product groups such as MSN-Search and SharePoint Portal Server.

Before Cambridge Hugo taught Computer Science and completed a Ph.D. at the LIP6 (U. Paris 6), under the supervision Patrick Gallinari, on the application of dynamic probabilistic models to a wide range of Information Access problems.
