Do you know anything about natural language processing?

One of the fundamental principles to understand is that computers are not inherently aware of the structure of a natural language document. Humans are trained early on to read and separate out words from text and understand those words. To a computer, a document is only a big sequence of bytes. The bytes come together to store characters. The characters all come together to form a document. Computers do not know that a space character between two sequences of characters means that there are two separate words in the document.
