  • In this paper I propose a generalization of lexical association techniques that is intended to facilitate statistical discovery of facts involving word classes rather than individual words. Although defining association measures over classes (as sets of words) is straightforward in theory, making direct use of such a definition is impractical because there are simply too many classes to consider. Rather than considering all possible classes, I propose constraining the set of possible word classes by using a broad-coverage lexical/conceptual hierarchy [Miller, 1990]. ...

  • In this chapter we define a simple stack. The first version uses procedures and a structure, the second version uses a class. The class version of the stack is very similar to the procedure/structure version of the stack, except that the procedures (member functions) and structures are integrated. That means that you don’t have to pass the structure as the first parameter to each procedure.

    '; echo 'Original width: ' . $this-_originalwidth . '

  • Compilation of all Java™ source files is no longer the only step necessary to build many Java-based projects. For the typical HelloWorld program, book examples, and simple applets, source file compilation is sufficient. Complex Java-based projects, like web applications or Swing-based programs (such as JBuilder), require much more. Up-to-date sources must be retrieved from source control. Dependencies not automatically handled by the Java compiler need to be managed. Various classes must be bundled and delivered to multiple locations, sometimes as JAR or WAR files.
