Cloud Mining automatically builds cool faceted search interfaces for your data. Simply get your data in a specific format, provide a custom look and feel for each search result and Cloud Mining does the rest.
fSphinx is a layer on top of Sphinx to perform faceted search. fSphinx powers the underlying backend of Cloud Mining and works with SimSearch (see project below) in order to combine full text with item based search.
SimSearch is an item based retrieval engine with Bayesian Sets. Bayesian Sets is a new framework for information retrieval in which a query consists of a set of items which are examples of some concept. The result is a set of items which attempts to capture the example concept given by the query.
Biomed Search was the largest search engine to look up images specifically in the biomedical domain. The system searches within captions and referring texts to images. Over one millions images were indexed. The projects was created in 3 months of works. Lucene was used for retrieval and web.py for the web framework. All the back end work was programmed in python.
Here is a presentation of Biomed Search given at the University of Cambridge.
I also contributed to UC Berkeley's Biotext Search Engine. Search within captions and abstracts of biomedical images. More information on this publication.
The admin we used at Cambridge for the summer school. It let us browse through the fast amount of candidates, comment on each applicant and assign scores. Try a demo, how to use it, get the source code on github.
Chiefmall started as a project to index all contractors in the USA. The idea was to form the basis of a social network for service professionals. All active licensed contractors in California and in 8 other states were listed. Contractors would be able to claim their listing thereby building up their own website. Some screenshots of the account, company description, service locations, portfolio, adding a caption, get jobs or getting your license verified.
Random automatic quizzes using wikipedia. An interesting experiment released before the word mashup was first coined and which received over 50,000 hits on the first three days it launched. WikiTrivia is now open source.
