I've worked in the NLP research area (mostly with statistical metrics), and I can safely say that 80% (precision) is the empirical threshold that most metrics are able to reach quite easily. The threshold between 80% and 90% starts to

I'm curious if anything related with teaching CS or how to program would be appelative to people? Something like 1:1 teaching/mentoring.. I teach CS (programming, web development, distributed systems) on a local university, but ha

I'm curious about your use cases, as I do not seem to find much information about model-driven development out there. Can you elaborate a little bit more about what you do with EMF? I'm asking this on the perspective of someone wh

I drove one of those Renault Twizy some years ago, and I can say it is not speed-limited by any means. In fact, it has a very good acceleration and top-speed around 100 km/h (at least, as I was afraid of turning it upside down on the h

I would say that a good example for starting in this field would be to implement something like Tf-Idf [0] for identifying keywords on a set of documents. I don't know where one can find current datasets for this, but I made WikiCorpus

The agreement with the CTO was to have a raise after 6 months. There was no previous agreement of a specific number, just a "raise". After 6/7 months I went to talk to one of the founders about that specific issue, i.e. that
