Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Java is a pretty awful language to put into a recipe book with a 66-character limit on lines for code. The overriding convention is that the code is ugly and we apologize.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Once the string is read in from the console, then classifier.classify(input) is called, which returns Classification."

A block of code is set as follows:

public static List<String[]> filterJaccard(List<String[]> texts, TokenizerFactory tokFactory, double cutoff) {
  JaccardDistance jaccardD = new JaccardDistance(tokFactory);

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public static void consoleInputBestCategory(
BaseClassifier<CharSequence> classifier) throws IOException {
  BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
  while (true) {
    System.out.println("\nType a string to be classified. " + " Empty string to quit.");
    String data = reader.readLine();
    if (data.equals("")) {
      return;
    }
    Classification classification = classifier.classify(data);
 System.out.println("Best Category: " + classification.bestCategory());
  }
}

Any command-line input or output is written as follows:

tar –xvzf lingpipeCookbook.tgz

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "Click on Create a new application."

Note

Warnings or important notes appear in a box like this.
