Techreport: Clustering and Classification in IR

I’ve just uploaded a technical report I wrote months ago, almost a year now. You can find it filed under my Publications page. The full title is “Clustering and classification in Information Retrieval: from standard techniques towards the state of the art“. I wrote this report when I was working for the SoLCo project at the University of Naples “Federico II”. SoLCo was an applied research project that aimed at bringing the state of the art of the information retrieval techniques to the Public Administration.

Information Retrieval is a wide branch. My role was to research and apply mainly clustering techniques, but also classification methodologies. This report was written at the early stages of the project.

Google and PHP optimisation

Back in June, this article appeared on Google Code, containing very superficial statements about how to optimise a PHP script. Fortunately, the community never sleep.
