A new approach to query-expansion based on the SPUD language model is available here.

April, 2015

Our paper which develops a new document language model for information retrieval using the Dirichlet-compound-multinomial distribution is available as an e-print (A Pólya Urn Document Language Model for Improved Information Retrieval) and has been accepted for publication in Transactions of Information systems. A Lucene implementation of the new retrieval method is available here.

June, 2014

I am currently a senior research associate at the NLIP group at the Computer Lab in Cambridge. I work in the ALTA institute on aspects of automated assessment of English text using different types of learning approaches. My broad research interests are in Information Retrieval (IR), Natural Language Processing, Databases, Data Mining, and Artificial Intelligence. I am still very much interested in theoretical aspects of information retrieval including aspects of ranking, score distributions, query performance prediction, and evaluation. I review for related journals (e.g. JASIST, Journal of IR, Journal of Intelligent Information Systems, Transactions on Information Systems) and help out with some conference programme committees too (e.g. GECCO 2009-2013, AICS 2010-2012, SIGIR 2013, ICTIR 2013, IRF 2013, ECIR 2014, ICTIR 2014, IRFC 2014, SIGIR 2014). A list of publications can be viewed here.
