Advantages of Assigned Indexing





Advantages of Assigned Indexing are overcoming the Problems of Natural Language in Indexing which are briefly given below.

Problems inherent in the language

Synonyms: as the preferred term is indexed and synonyms or related terms direct the user to the preferred term



Homographs: removes any confusion caused by homographs by the inclusion of a qualifying term



Use of Plural-Singular Forms



Multi-Worded Concept



Complex Subject

Problems Pertaining to Relationships

(or Assignment Indexing or Concept Indexing) in an indexing method in which the human indexer selects one or more subject headings or descriptors from a list of controlled vocabulary (e.g. subject headings lists, thesaurus, or classification schemes) to represent the subject matter of the work. Since the Assigned Indexing uses the controlled vocabulary to give the indexing terms selected to represent the subject content of a work, so in this technique there is no need for the index terms to appear in the title or text of the document indexed.In indexing, if the terms are selected from the title or the text of a document and used without any alteration as index terms, then this is referred to as natural language indexing or derived indexing. Derived Indexing solely relies on information which is manifest in the document, without attempting to add to this from indexer’s own knowledge or other sources. By doing so we have to face the problems of. If however, the selected terms are translated or encoded intoby the help of a prescribed list (e.g., Library of Congress Subject Headings, Library of Congress Classification, Dewey Decimal Classification), then the indexing language becomes controlled or artificial. This process is called Assigned Indexing.If we are to use a list of words to help us in our searching, we would increase the chances of achieving successful matches if we used the same list of words to encode the appropriate words to the documents ourselves rather than rely on authors’ choice. In other words, we devise an indexing language and use this for both encoding operations: input and question. Such systems are referred to as. Assigned indexing involves an intellectual process. Subject heading schemes, thesaurus and classification schemes are the popular forms of assigned indexing.Assigned indexing is also known as concept indexing because what we are trying to do is to identify the concepts involved in each document.Subject heading schemes (e.g. LCC, DDC, LCSH, SLSH), thesaurus (e.g. Roget's Thesaurus), and classification schemes (e.g. DDC, LCC, UDC) are the popular forms of assigned indexing.Check the example of the following bibliographic record which is given from our article Cataloging Metadata Examples : RDA AACR2 LCSH LCC DDC MARC-21 BIBFRAME Etc. In this catalog record, the subject of this book is given in the form of LCSH headings, DDC number, and LCC number. This subject representation is an example of Assigned Indexing as the subject headings are given from the controlled vocabulary LCSH and class numbers are given from the classification schemes DDC and LCC.
