Subject September Hadoop Get Together
Date Mon, 24 Aug 2009 22:17:11 GMT
I would like to announce the September-2009 Hadoop Get Together in newthinking 
store Berlin.



       When: 29. September 2009 at 5:00pm
       Where: newthinking store, Tucholskystr. 48, Berlin, Germany



As always there will be slots of 20min each for talks on your Hadoop topic. 
After each talk there will be a lot time to discuss. You can order drinks 
directly at the bar in the newthinking store. If you like, you can order 
pizza. There are quite a few good restaurants nearby, so we can go there 
after the official part.

Talks scheduled so far:

Thorsten Schuett, Solving Puzzles with MapReduce: MapReduce is most often used 
for data mining and filtering large datasets. In this talk we will show that 
it also useful for a completely different problem domain: solving puzzles. 
Based on MapReduce, we can implement massively parallel breadth-first and 
heuristic search. MapReduce will take care of the hard problems, like 
parallelization, disk and error handling, while we can concentrate on the 
puzzle. Throughout the talk we will use the sliding puzzle 
(http://en.wikipedia.org/wiki/Sliding_puzzle) as our example.

Thilo Götz, Text analytics on jaql: Jaql (JSON query language) is a query 
language for Javascript Object Notation that runs on top of Apache Hadoop. It 
was primarily designed for large scale analysis of semi-structured data. I 
will give an introduction to jaql and describe our experiences using it for 
text analytics tasks. Jaql is open source and available from
 http://code.google.com/p/jaql.

Uwe Schindler, Lucene 2.9 Developments: Numeric Search, Per-Segment- and
Near-Real-Time Search, new TokenStream API: Uwe Schindler presents some new 
additions to Lucene 2.9. In the first half he will talk about fast numerical 
and date range queries (NumericRangeQuery, formerly TrieRangeQuery) and their 
usage in geospatial search applications like the Publishing Network for 
Geoscientific & Environmental Data (PANGAEA). In the second half of his talk, 
Uwe will highlight various improvements to the internal search implementation 
for near-real-time search. Finally, he will present the new TokenStream API, 
based on AttributeSource/Attributes that make indexing more pluggable. Future
developments in the Flexible Indexing Area will make use of it. Uwe will
show a Tokenizer that uses custom attributes to index XML files into various
document fields based on XML element names as a possible use-case.

We would like to invite you, the visitor to also tell your Hadoop story, if 
you like, you can bring slides - there will be a beamer.

A big Thanks goes to the newthinking store for providing a room in the center 
of Berlin for us.

Hope to see you soon in Berlin,
