I am trying to create my own and simple feature selection algorithm. The data set that I am going to work with is here (very famous data set). Can someone give me a pointer on how to do so? I am p...

How can I find if an attribute is synthesized or inherited from the productions of a grammar? I guess for that the attribute must be predefined in the problem -- if its value depends on child or p...

Is there any diff/merge tool for programming languages, that works in a syntax-aware way (like XML Diff Tool), doing more than compare line-by-line (and optionally ignoring whitespace). I'm inter...

I've been reading a bit about how interpreters/compilers work, and one area where I'm getting confused is the difference between an AST and a CST. My understanding is that the parser makes a CST, h...

I came across several methods for measuring semantic similarity that use the structure and hierarchy of WordNet, e.g. Jiang and Conrath measure (JNC), Resnik measure(RES), Lin measure (LIN) etc. T...

I have created a context free grammar in bison and a scanner in flex. Now i also want to make a semantic check, for example, suppose the input is something like this: int m=5; c=c+5; This input ...

How can you determine the semantic similarity between two texts in python using WordNet? The obvious preproccessing would be removing stop words and stemming, but then what? The only way I can t...

How is the semantic analysis done by a compiler (generally)? I had to answer to this question during my last exam, it wasn't enough for the professor. I included BNF (with an example) and s...

I have written a basic compiler which generates an AST, correctly taking account of the operator precedence in expressions. However, when performing code generation to produce C++ code, I'm unsure ...

I'm looking for any free tools/components/libraries that allow me to take anvantage of text mining, fact extraction and semantic analysis in my .NET application. The GATE project is what I ...

Is there a research paper/book that I can read which can tell me for the problem at hand what sort of feature selection algorithm would work best. I am trying to simply identify twitter messages ...
