Nice Nhet

Looking back many years ago, library’s information retrieval systems has evolved and improved dramatically. From the traditional type like catalog and indexes, here we are with the fast and reliable computers. This technology in the library makes the searching easy and fast.

Classical information retrieval is text retrieval kind of IR. These are usually the library patrons and more on recall based searching. You usually need bunch of references in a particular topic and could possibly offer one correct answer and small or limited pieces of information only.

However, in the Web information retrieval we are searching more using different task and with high precision. No more exhausted searching. Web-based searching is a magic to everyone. It is available anywhere and anytime and with unlimited searching. it has a great impact to everyone and has help the world of business, entertainment, academic etc.

Web-based information retrieval in the library contributes to fast delivery of information to the users.

Personally, I enjoyed searching using the web but it doesn’t necessarily mean that I will forget the books which are more reliable. I may say that web-based searching is an additional reference but we should not be dependent on it because not all information found in it is 100% reliable.

Looking at the overall picture, web-based searching is more challenging, easier and faster compared to the traditional one but at some aspects books and printed materials are more dependable in a research.
