Information Analysis and Repackaging

Notes 1.2. How Vocabulary Control is Achieved (1.2)

Vocabulary control is achieved by three principal methods:
• Defining the scope, or meaning, of terms
• Using the equivalence relationship to link synonymous and nearly synonymous terms; and
• Distinguishing among homographs.
The Standard provides guidelines for constructing controlled vocabularies:
• selecting the terms
• formulating the terms
• establishing relationships among terms, and
• presenting the information effectively in printed, online, and web navigation sites.

1.3. Purpose of Controlled Vocabularies (5.1)

The purpose of controlled vocabularies is to provide a means for organizing information. Through
the process of assigning terms selected from controlled vocabularies to describe documents and
other types of content objects, the materials are organized according to the various elements that
have been chosen to describe them.
There are many different kinds of controlled vocabularies. Some common ones are:
• Simple lists of terms or “pick lists”
• Synonym rings
• Taxonomies
• Thesauri

Controlled Vocabularies Serve Five Purposes:
1. Translation: Provide a means for converting the natural language of authors, indexers,
and users into a vocabulary that can be used for indexing and retrieval.
2. Consistency: Promote uniformity in term format and in the assignment of terms.
3. Indication of relationships: Indicate semantic relationships among terms.
4. Label and browse: Provide consistent and clear hierarchies in a navigation system to
help users locate desired content objects.
5. Retrieval: Serve as a searching aid in locating content objects.

Automatic Indexing

SimpleIndex Automatic Indexing Software is designed to streamline the single-user scanning
workflow employed by most desktop scanners. SimpleIndex lets you define the entire scanning
process from beginning to end, then execute the steps in that workflow automatically. This minimizes
user training and interruptions for input during the scanning process.
But just because SimpleIndex is designed for the desktop doesn’t mean it lacks the powerful
automation features found in enterprise Automatic Indexing Software.
