Detect most likely words from text without spaces / combined words

阅读更多关于 Detect most likely words from text without spaces / combined words

问题 Is there a good library can detect and split words from a combined string? Example: "cdimage" -> ["cd", "image"] "filesaveas" -> ["file", "save", "as"] 回答1: Here's a dynamic programming solution (implemented as a memoized function). Given a dictionary of words with their frequencies, it splits the input text at the positions that give the overall most likely phrase. You'll have to find a real wordlist, but I included some made-up frequencies for a simple test. WORD_FREQUENCIES = { 'file': 0

问题 I have been trying to get my EditText box to word wrap, but can\'t seem to do it.

However, the issue remains, and I have a large text box that is only allowing me to enter text on one line, continuing straight across, scrolling horizontally as I enter text. Here is the XML code for the EditText object from my layout file. <?xml version=\"1.0\"

For example, "iPhone has two hundred and thirty thousand seven hundred and eighty three apps" would become "iPhone as 230783 apps" Before i start coding, I would like to know if any function / code exists for this conversion. There are lots of pages discussing the conversion from numbers to words. Not so many for the reverse direction. The best I could find was some pseudo-code on Ask Yahoo.

First, I created a UILabel subclass and overrode the touchesEnded:withEvent: method to determine the touched CGPoint. I also wrote a method that compute the corresponding \"frame\" (CGRect) of each word of the text using sizeWithFont:forWidth:lineBreakMode:. With the touched CGPoint and this frame, I can
