Supplied Thesaurus

Although Oracle Text does not provide a default thesaurus, Oracle Text does supply a thesaurus, in the form of a file that you load with ctxload, you can use to create a general-purpose, English-language thesaurus.

You can use the thesaurus load file to create a default thesaurus for Oracle Text, or you can use it as the basis for thesauruses tailored to a specific subject or range of subjects.

• Supplied Thesaurus Structure and Content: The supplied thesaurus is similar to a traditional thesaurus, such as Roget’s Thesaurus, in that it provides a list of synonymous and semantically related terms.

  It provides additional value by organizing the terms into a hierarchy that defines real-world, practical relationships between narrower terms and their broader terms.

  Additionally, cross-references are established between terms in different areas of the hierarchy.

• Supplied Thesaurus Location: The exact name and location of the thesaurus load file depends on the operating system; however, the file is generally named dr0thsus (with an appropriate extension for text files) and is generally located in the following directory structure:

  <Oracle_home_directory> <Oracle_Text_directory> sample thes
