I'm looking for a way to automatically extract domain-specific knowledge from unstructured text in Java. We would have a manually annotated training set at our disposal that contains the following:
Text: The apartment contains 2 bedrooms and one bathroom.
Structured
- Type: apartment
- Bedrooms: 2
- Bathrooms: 1
Any idea what's the best way forward to train a model that would be able to perform this job? Possibly a POS-tagger that we extend with custom tags?
Thanks!

Want solution in Java which does the following:
Input :
Locale code (Example: "en_US")
Postal code(Example: "NH 3301") --> Valid
Similarly for any other country in the World, it should validate the corresponding Postal code.
Is there any Library for accomplishing this?
You can go for GeoNames .
It provides us geographical database containing millions of placeholders and it covers almost all countries.
Hope this helps.

I'm looking for an open source API allowing to manage events in Java. My needs are to create .ics file that contains one (or many) event(s) in order to synchronise them.
Also it will be very helpfull if this API can manage update (ie : if we can update event that we first create with the same system).
I've used ical4j (https://code.google.com/p/ical4j/) for similar problems some months ago.
This should give you a good start to solve your problem.

I'm looking for a simple solution of how to generate pdf from html template preferably in Scala (it could be a Java library as well). Just for information, I need to use it in a Web application made by Play Framework or Lift.
This is for Java, free as long as you don't use it for commercial purposes. http://itextpdf.com/
yes itext is a nice library for starting learning about text to pdf conversion and the reverse.

I have a websockets connection sending data to and from the server. I am thinking it will be fastest if I use a binary protocol to serialise and deserialise all messages instead of using JSON.
Are there any existing tools that would do this that work in Java/Scala and JavaScript?
Short answer: You probably do not need to as you probably won't notice the gain.
There is BSON http://bsonspec.org/ which is binary JSON. Explain more what kind of data and the amount of data you are dealing with if you really think you need to.

I want a rule engine to calculate the truth values of formulas (and/or) + inferring new rules from the current KB.
I searched most of the rule engines but I can not find a concrete example. Could you please help me with an example?
I would suggest open source Drools for your requirements. Please take a look at this tutorial: http://www.developer.com/java/ent/article.php/10933_3821101_4/Rev-Up-the-Drools-5-Java-Rule-Engine.htm
Rules and inferencing are big topics in the semantic web world. You can model an ontology in OWL and run a reasoner over your model and instance data and produce inferred facts. The Jena framework has an excellent rules engine with native support plus drop in reasoner support for many of the current semantic web favorites such as Pellet, Racer and FaCT. See http://jena.sourceforge.net/inference/
