Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Selective Dissemination of Information (SDI) is a personalized information service designed to keep users informed about new documents and research relevant to their specific interests.
Step 1:Understanding SDI.
SDI matches newly available information with the user's research profile or subject interest and sends relevant information selectively.
Step 2:Origin of SDI concept.
The concept of SDI was introduced by H. P. Luhn of IBM in 1958. He was a pioneer in information retrieval and documentation systems.
Step 3:Conclusion.
Thus, the correct answer is Option (B).
