This essay does not describe an existing computer program, just one that should exist. This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. I have no source, object, specifications, file layouts or anything else useful to implementing this project. Everything I have prepared to help you is right here.
This project outline is not like the artificial, tidy little problems you are spoon-fed in school, when all the facts you need are included, nothing extraneous is mentioned, the answer is fully specified, along with hints to nudge you toward a single expected canonical solution. This project is much more like the real world of messy problems where it is up to you to fully the define the end point, or a series of ever more difficult versions of this project and research the information yourself to solve them.
Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; or give you any additional materials. I have too many other projects of my own.
Though I am a programmer by profession, I don’t do people’s homework for them. That just robs them of an education.
You have my full permission to implement this project in any way you please and to keep all the profits from your endeavour.
Please do not email me about this project without reading the disclaimer above.As the world has become a global village, the problem of file encodings has become more acute. Now a file created on one side of the planet may be read on another. It is not obvious which encoding scheme was used. There are hundreds of possibilities.
Unfortunately, the encoding scheme used is not usually embedded as a signature in the document. See encoding identification for a fuller description of the problem.
Your job is to look at the document and make an educated guess at the encoding scheme used to encode it. You might provide a list of guesses in descending order of probability for someone to make the final decision manually.
There are two parts to the project.
You also might want to tackle this as a neural net problem. Teaching it with thousands of documents with known encoding.
If you have control over the source of the documents, you can sidestep the problem by embedding the encoding as the first field followed by a line terminator. Better still, settle on UTF-8 or UTF-16BE as your encoding and be done with the problem.
Files are sometimes labelled with what they are in the first few bytes in a signature.
