I have been playing with different Map/Reduce tools and examples to acquire the whole of view of this programming to solve different problems. Basically there are several patterns that can be identified when you need to tackle the implementation of some algorithm. I would like to leave some references that have served as inspiration:
In the same way I have prepared some slides compiling some basic examples that I have adapted from the original sources to deliver my own tutorial. I firmly believe that the best way of learning someting is try to explain to others so I hope to extend these slides in the future covering most of the patterns with different examples. At the moment I am going to
leave here the presentation:
Now it is time to play with Impala-Cloudera
…I will keep you inform of the progress!
Last and this week I have been preparing an introduction about the Map/Reduce algorithm I have found a lot of new excellent references (see my previous post) and I have read some books that I did not know. As a result I have made a compilation (it is just a summary that I will continue updating) that can serve as roadmap about what MapReduce is and what you can do with this programming model. As soon as I review my presentation and the examples I will upload them,
Hi! I have been a little bit lazy about writing in the blog but it is now time of recovering good practices. I am going to summarize my tasks during the last two weeks,
Reading (pi = persona interest)
Writing, reviewing and researching
- I am managing a Special Issue in the Journal of Computers in Industry, Elsevier.
- I finished the review of a book for Manning Publications.
- I have been included as Technical Development Editor in Manning Publications.
- I have been included as PC member in the workshop proposal “Data Mining on Linked Data (DMoLD’13) workshop with Linked Data Mining Challenge” thanks to my colleagues at the University of Economics in Prague.
- I am reviewing a paper for the journal “Expert Systems with Applications” (IF: 2.203)
- I am reviewing and finishing the paper with my colleague Alejandro Montes about his final Master Project.
- I have had a meeting with my SEERC colleagues to talk about next actions.
- I have had a meeting with Michalis Vafoupolus to prepare the Linked Data Cup paper.
- I have had two meetings with Lum about his Bachelor Degree Project. It is a kind of supervising to address the problem of sentiment analysis using Rapidminer, Lingpipe, Alchemy API and a custom solution.
Coding and Tools
- I have made in my leisure time a tool for unifying company names called CORFU using Python, NLTK and the APIs of Google Places, Linkedin and Google Suggestions. It also includes other algorithms based on string similarity, etc.
- I have developed a simple sentiment analyzer using Alchemy API.
- I have adapted some examples of Map Reduce patterns
- I continue my fight to learn Greek…I have to study a bit more!
This is all I can remember…perhaps I am missing something…!
