Examples of post coordinate indexing system

Subject indexing is used in information retrieval especially to create bibliographic indexes to retrieve documents on a particular subject. Examples of academic indexing services are Zentralblatt MATH, Chemical Abstracts and PubMed. The index terms were mostly assigned by experts but author keywords are also common.

Introduction  Developed by Mortimer Taube in 1953  It is a simple post-coordinate indexing system.  It creates index entries for each unit term identified by the indexer.  In fact, a card is prepared for each term that is considered to be an appropriate index term for a given document. 3.  The term is posted on top of the card. Keyword in Context (KWIC) Indexing system is based on the principle that the title of the document represents its contents. It is believed that the title of the document is one line abstract of the document. The significant words in the title indicate the subject of the document. a KWIC index makes an entry under each significant word in the title, along with the remaining part of the title to Indexing - SlideShare INDEXING INDEXING AND ABSTRACTING Course Overview The present era has been described as The Information Age.

For example, the indexes to abstracting and indexing journals, national bibliographies and subject indexes to library catalogs apply principles of pre-coordinate indexing in varying measures. Such indexes are compiled both manually as well as with the help of a computer. In postcoordinate indexing, complex subjects are represented by several different headings rather than a single heading. For example, a history of Arizona might be assigned the headings 'Arizona' and 'History'. In precoordinate indexing, the work might be given a single heading, 'Arizona - History'. In a post-coordinate system, a single concept is represented by a single term. We’re not combining two concepts, we are keeping them separate. That way we are able to do a large amount of automated indexing. If we try to mine the text at the beginning, it is very system-intensive. So, we have taken another path, by and large, for that.
