We are building an ontological model of all the things which are bought and sold on eBay.

Towards our goal, we are working on constructing the product ontology (persistent knowledge of products and how they are connected), extracting the attribute genome of products & their relationships.

We are also building a large scale data store and processing platform to support our work.

Common tasks of the job include, but not limited to, developing classifiers and knowledge extraction algorithms to extract knowledge & information from the documents, designing graph computation algorithms to connect things & propagate information, training classifiers, building the UX demo prototypes to drive backend development, and all related large scale data mining and machine learning work.

Location could be San Jose, San Francisco, Portland, Austin or NYC.

What the heck does all that jargon mean?
