  1. Organizing information what is means Ch1 – organizing information from the shelf to the web

  2. Outline • Introduction • Information services in today word • Think for a minute about what you do when you are in need of information.!! • Information organization • Why organize information? • How do we organize information? • The way and tools of information organization

  3. Introduction • User today can obtain access to information from a variety of sources through a wide range of channels from conventional bibliographic resources (ex: book) to a myriad of electronic resources(ex : e-book) . • One of the major challenges is how best to organize these information resources , available as they are in their widely differing forms and format.

  4. Information services in today word • User today can access information resources and services through a variety of channels such as : • Library OPAC (online public access catalogues) • Online bibliographic or full test database • E-book and e journal • Websites • Subject gateways : it is provide access to selective web resources in one or more specific discipline. • Digital libraries : Ex ACM ( American computing machinery) .

  5. Think for a minute about what you do when you are in need of information.!! • First, you recognize that information might help you solve a problem or answer a question. • Second, you know that there might be an article or a book or a website that has the information you need. • You set off to the library in search of that article or book or use the internet. • You start looking up the topics you are interested in, or maybe you know an author who writes about what you are interested in, or maybe someone mentioned a title of a book.

  6. Cont • In the library catalogue or any search engine you find records that describe items in the collection. • When you discover just the item that seems relevant to your question or problem : • You ether head to the shelves to retrieve the item or click the link . • once at the shelves, you see the orderly arrangement of the books and can quickly find the one you are interested in using the call number on the spine of the book. Or you see similar items in the website.

  7. Information organization • Information organization : is the processes and practices of describing and representing information objects (containers and content), and identifying the connections and relationships between the objects and the people responsible for their creation and/or production. • Information organization is fundamentally about information access.

  8. Why organize information? • To create order from chaos. • To find what we need more efficiently. • To manage large collection of items. • Creating better ways to find information is a critical reason for organizing it. • Help users access to the information. • To facilitates information easy identification and retrieval.

  9. Why organize information? (cont) • To find the information again easily. • Save users time. • Think about the value that add to the information by organizing it. • The better information organization systems respond to our users, the more likely they will continue to use our services.

  10. Why organize information? (cont) As professionals • Help and connect users with relevant information. • Helping users to decide between several items (i.E., Make judgments about The items). • professionalsdo this through the representations they create catalogues, indexes, and other finding aid.

  11. How do we organize information? • The "how" of information organization is the way that add the value. • Have we organized it in such a way that users will be satisfied and return again and again for information services and centers?

  12. How do we organize information?(cont) First, • We organize information by representing it. • We represent both the container that holds the information and we represent the content: what the information is about. • The metadata is representation of the information resource .

  13. How do we organize information?(cont) • How we organize information must be geared to the users of our system. • We can imagine all kinds of ways to organize information (e.g., by colour of the cover, number of pages, etc.) • but if our organization system is not responsive to our users we will not produce a system that adds value and ultimately may not be used.

  14. How do we organize information? (cont) • Next, Organize information based on the tried and true methods of lumping and splitting. • We lump information together by showing similarities between two items. • For example, Mark Twain was the author of many books. We can lump all books by Mark Twain together based on the similarity of authorship. • We split information into groups based on how items are different. • For example, Mark Twain has been the subject of many books (e.g., critical essays, biographies, etc.) We can split the books that are by Mark Twain from those that are about Mark Twain based on the differences between those written by versus those written about him.

  15. The way and tools of information organization • Classification • Cataloguing • Library catalogs • Subject heading

  16. Classification • Classification : is the process of assigning elements or units to classes or types according to some criteria. • The objects we classify have attributes with values. • Attributes may, for example be color or weight • Values may be red or heavy. • Classifications are made by considering different attributes and their values.

  17. Classification • It is important to realize, however, that any set of objects may be classified in an unlimited number of ways. • Classification we use characteristics of object that are specifically useful for their identification by the user. • Classification provides a descriptive and explanatory framework for ideas and a structure of the relationship among the ideas. • Example: Science > Chemistry > Organic Chemistry

  18. Classification schemes The same thing can be viewed form different disciplines. EX: • Sports > Racing > Horse Racing • Science > Biology > Zoology > Horses > Horse Racing • Purpose of classification: • Identify things that have similar characteristics. • Separate things that have dissimilar characteristics

  19. Cataloguing • Everyday we use different type of catalogs (i.e. IKEA) • A catalogue: is a list of contents of a particular collection of objects and is arranged in some definite order so as to facilitate the use of that collection and as a guide to its scope and content.

  20. Purpose of Cataloguing • Provide information about every item in the collection • Provide the necessary detailed of each item • Arrange all the entries in a convenient order so that it is easy to find an item

  21. The challenges for producing catalogue • What sort of information should be provided about items • How organize entries so that customers can find items easily. • How to update the catalogue(ex: add , delete) • How to enter and process the data so that entries can be generated to used in print and electronic form . • The data can be transferred among various agencies for various management reasons.

  22. Library catalogs • Enable person to find a book of which either author, title , subject is known • To show what the library has for a given author, on a given subject, in a given type • To assist with the choice of the book by edition or by its character (literary or topical) • In the library catalogs it is important to know: • Location • Physical characteristics (e.G. Oversize) • Circulation properties

  23. Subject heading • The library classification schemes help the user to find a specific information resource. • Subject heading : it is defined terms provides a verbal representation of their subjects and are used as index terms by users to facilitate their search. • Subject heading: it is used to describe the subject of a document or a class of documents. • The user can search by the subject heading ex: e-commerce .
