Term Selection
The second stage of indexing involves the translation of the subject analysis into a set of index terms. This can involve extracting from the document or assigning from a controlled vocabulary. With the ability to conduct a full text search widely available, many people have come to rely on their own expertise in conducting information searches and full text search has become very popular. Subject indexing and its experts, professional indexers, catalogers, and librarians, remains crucial to information organization and retrieval. These experts understand controlled vocabularies and are able to find information that cannot be located by full text search. The cost of expert analysis to create subject indexing is not easily compared to the cost of hardware, software and labor to manufacture a comparable set of full-text, fully searchable materials. With new web applications that allow every user to annotate documents, social tagging has gained popularity especially in the Web.
One application of indexing, the book index, remains relatively unchanged despite the information revolution.

Famous quotes containing the words term and/or selection:
“I am a colored woman or a Negro woman. Either one is OK. People dislike those words now. Today these use this term African American. It wouldn’t occur to me to use that. I prefer to think of myself as an American, that’s all!”
—Annie Elizabeth Delany (b. 1891)
“The books for young people say a great deal about the selection of Friends; it is because they really have nothing to say about Friends. They mean associates and confidants merely.”
—Henry David Thoreau (1817–1862)
