PRE-COORDINATE SUBJECT INDEXING SYSTEMS

Nowadays most of the documents deal with complex and compound subjects, each comprising a number of components or concepts. The coordination of these component terms is either done at the input stage or at the output stage. The index in which the coordination of components (index terms) is done at the input stage, is known as a pre-coordinate index. Coordination of index terms at the input stage means coordination of index terms at the time of preparation of the index by the indexer. In pre-coordinate indexing, a number of selected terms or keywords are coordinated by the indexer and the cards are prepared for display to the users.

Examples: Ranganathan’s Chain Indexing, G. Bhattacharya’s POPSI, and Derek Austin’s PRECIS, COMPASS, etc.

Come to GSLIS: the iSchool at Illinois! [Library and Information Science Videos : FEATURED VIDEO]
https://librarianshipstudies.blogspot.com/2017/04/library-and-information-science-videos.html
#LIBRARIANSHIPSTUDIES

==================================

Why should you attend the Graduate School of Library and Information Science at The University of Illinois, Urbana-Champaign? This video explains. The School of Information Sciences, also The iSchool at Illinois, is a graduate school at the University of Illinois at Urbana-Champaign. Its Master of Science in library and information science is currently accredited in full good standing by the American Library Association. The school offers the Master of Science in library and information science (MS/LIS; comparable to the Master of Library and Information Science), Master of Science in information management (MS/IM), Master of Science in bioinformatics, a Certificate of Advanced Study (CAS), and a PhD. The School of Information Sciences' MS/LIS degree has been ranked as the top library and information science (LIS) graduate program in the country by U.S. News & World Report since 1996. In the Research and Markets' 2008-2009 Survey of Academic Libraries, Illinois was ranked the number one library and information science program in the U.S. and Canada.

Library and Information Science Videos is an initiative of Librarianship Studies & Information Technology blog to showcase the finest LIS videos for librarians, catalogers, metadata, archives, and knowledge professionals. The videos are sourced from Librarianship Studies & Information Technology YouTube Channel which are organized based on the categories (or labels) of Librarianship Studies blog.

A featured video will be displayed in this blog post along with a brief summary. It will also be displayed at the bottom of the blog in a large view (recommended). It is important to note that the large view of the featured video is available only in the web version. So if you are viewing on a mobile phone or some mobile device then go to the bottom of the blog post area to locate and visit the option "View web version" to find the featured video.

BACKGROUND

I always wanted to see beautiful libraries of the world like the Library of Congress of Washington D.C., the British Library of London, and the Bodleian Library of Oxford. I also wanted to view Library and Information Science tutorial videos by top-ranked library and i-schools. There are some topics which cannot be demonstrated effectively through text (as in article form), where video format is preferred. For example, if the subject is like Use of Robots In Libraries, then it would be more interesting to see a video showing robots in action in libraries. Likewise, a biography of a library and information science luminary like Dr. S. R. Ranganathan, Dr. Carla Hayden, Lois Mai Chan, or Charles Ammi Cutter should better be viewed in a video. So an idea came to my mind to create a YouTube Channel on Library and Information Science with top quality videos on the pattern of Khan Academy.

Library and Information Science Videos supports the purpose of Librarianship Studies & Information Technology to provide leadership for the development, promotion, and improvement of library and information services and the profession of librarianship in order to enhance learning and ensure access to information for all. Librarianship Studies & Information Technology blog is envisioned as the Britannica, The Huffington Post, Khan Academy, and more closely like the Encyclopedia of Library and Information Sciences; an authoritative source for consultation and reference for any library or information profession related issue and a treasure hub of knowledge on Library and Information Science, which is open and free for all the library professionals worldwide.

FEATURED VIDEO

Dr. Carla Hayden: President Obama's Nominee For The Librarian Of Congress - [Watch this video on the large screen at the bottom of Librarianship Studies & Information Technology blog - Recommended] - This video is created by Obama White House Archives to introduce Dr. Carla Hayden as President Obama's Nominee For The Librarian Of Congress. See Dr. Carla Hayden in action as she speaks about her career and experience as a librarian, and tour the Library of Congress and Enoch Pratt Free Library with this incredible video.

VOCABULARY CONTROL
#LIBRARIANSHIPSTUDIES

The term ‘vocabulary control’ refers to a limited set of terms that must be used to index documents, and to search for these documents, in a particular system. It may be defined as a list of terms showing their relationships and used to represent the specific subject of the document.

An information system may help the user by explicitly assigning index terms (that is, words or notations) to the documents and controlling, at least in the case of alphabetical (word) systems, the semantic and often the syntatic relationships between these index terms the words (which may be subject headings or descriptors) are assigned from recognized subject heading lists or thesauri, and the notations from recognized classification schedules, and thus use controlled vocabulary. A controlled vocabulary is one in which there is only one term or notation in the vocabulary for any one concept. The Library of Congress List of Subject Headings is an example of a controlled alphabetical vocabulary, and the Dewey Decimal Classification is an example of a notational vocabulary (By definition, all notational vocabularies must be controlled).

The controlled vocabulary performs several tasks:
It usually explicitly records the hierarchical and affinitive/associative relations of a concept. Examples: Allergy, narrower-term: Hay fever; 385 (Railroad transportation), 381.1 (economic aspects of railroad transportation)
It establishes the size and scope of each topic. For example, whether or not the word baseball or the notation 796.357 is to include the concept softball.
In addition, for word based systems, the controlled vocabulary identifies synonyms terms and selects one preferred term among them. For homonyms, it explicitly identifies the multiple concepts expressed by that word or phrase. In short, vocabulary control helps in overcoming problems that occur due to natural language of the document’s subject. Hence, if vocabulary control is not exercised different indexers or the same indexer might use different terms for the same concept on different occasions for indexing the documents dealing with the same subject and also use a different set of terms for representing the same subject at the time of searching. This, in turn, would result in ‘mis-match’ and thus affect information retrieval.

Problems of Natural Language in Indexing
#LIBRARIANSHIPSTUDIES

A new article in the Librarianship Studies & Information Technology blog provides an exhaustive description of Problems of Natural Language in Indexing.

Derived indexing is based on the natural language of the documents which proves to be problematic sometimes in the Subject Indexing Process. These problems prompted to move towards the use of Assigned indexing. These problems can be categorized under two heads:
1. Problems inherent in the language
2. Problems pertaining to relationships
