Where I find a collection of document for information extraction? - document

I am the beginner with the GATE framework, I'm finding a valid set of documents (pdf or other) where I can learn better this framework. On google I can not find anything appropriate, do you help me?

Please see: https://gate.ac.uk/wiki/quick-start/ on the gate website.
They also have training modules with materials to get started.
I am also starting with Gate... Good luck =)

SVM in Point Cloud Library

Does anyone know the difference between:
pcl/ml/svm.h VS pcl/ml/svm_wrapper.h
Also does anyone know if there is a official tutorial for this build in SVM lib?
I tried to search a lot but could not find anything except forum threads.
If anyone looking at this svm_wrapper.h includes the svm.h. I am not sure why it has this structure. I found a semi-tutorial here.

Semantics based code search

We have a large number of repositories. We want to implement a semantics(functionality) based code search on those repositories. Right now, we already have implemented keyword based code search in which we crawled through all the repository files and indexed them using elasticsearch. But that doesn't solve our problem as some of the repositories are poorly commented and documented, thus searching for specific codes/libraries become difficult.
So my question is: Is there any opensource libraries or any previous work done in this field which could help us index the semantics of the repository files, so that searching the code becomes easy and this would also help us in re-usability of the codes. I have found some research papers like Semantic code browsing, Semantics-based code search etc. but were of no use as there was no actual implementation given. So can you please suggest some good libraries or projects which could help me in achieving the same.
P.S:-Moreover, companies like Koders, Google, cocycles.com etc. started their code search based on functionality. But most of them have shut down their operations without giving any proper feedback, can anyone please tell me what kind of difficulties they are facing.
not sure if this is what you're looking for, but I wrote https://github.com/google/zoekt , which uses ctags-based understanding of code to improve ranking.
Take a look at insight.io
It provides semantic search and browsing

what algorithms does AlchemyAPI use?

I'm trying to develop something that extract keywords from a text. I know AlchemyAPI work best for this. Now i wanna know what algorithms AlchemyAPI used so that i can implement code of it on my own. Does anyone has any idea about it. Please share it. Thanks in advance.
I have no idea what specific algorithms AlchemyAPI uses (I'm guessing it is on the extreme end of proprietary), but the Stanford NLP has a lot of information and code that may be useful:

how to design a full-text indexing system?

Lucene is a great open source indexng library, my problem is not about how to use this kind of indexing tool, but to learn and understand how they are designed.
Maybe I should read the source code of Lucene, but I can't seem to find any tutorial about how this great work is done.
So, is there any other way or a book that can help me gain a concrete understanding of how to design such a indexing system?
Thank you.
The science behind Lucene is called as Information Retrieval. When you start appreciating the Algorithms and Data Structures behind Information Retrieval, you are all done and Lucene or Sphinx would merely be tools to solve your tasks. The very first thing is you can go through Inverted Index Data Structure.
A great book about Information Retrieval Algorithms and Data Structure can be found here: http://nlp.stanford.edu/IR-book/ This Stanford text is a good resource and a good starting point in coming to know about how Information Retrieval Systems are designed

Nodejs template system documentation

I want to create my own template system for node.js (just for educational purposes), but I can't find any useful information to start with. Are there any good tutorials out there which could help me?
Thanks!
Jison docs would be a good place to start. A breakdown of how it's used to build a parser for the CoffeeScript grammar may be helpful in seeing the big picture.
