Question

What is the sequence of functional flow of SDI Service? A. Analysis of responses, B. Feedback, C. Matching, D. SDI Notifications, E. Profiles Modification.

• A. E, D, C, A, B
• B. D, E, C, B, A
• C. C, D, A, B, E
• D. C, D, B, A, E

Hint:

SDI works by matching profiles, sending notifications, taking feedback, analysing responses and modifying profiles.

Answer 1

The Correct Option is D

Concept: SDI means Selective Dissemination of Information. It is a personalized current awareness service where user profiles are matched with new documents.

Step 1: Start with matching.
The first functional step is matching the user profile with newly available documents. \[ C = \text{Matching} \]

Step 2: Send SDI notifications.
After matching, relevant information is sent to the user as SDI notification. \[ D = \text{SDI Notifications} \]

Step 3: Collect feedback.
The user gives feedback on whether the received information is useful or not. \[ B = \text{Feedback} \]

Step 4: Analyse the responses.
The responses are analysed to understand the user's real information needs. \[ A = \text{Analysis of responses} \]

Step 5: Modify profiles.
Finally, the user profile is modified to improve future SDI service. \[ E = \text{Profiles Modification} \] Thus, the correct sequence is: \[ C,\ D,\ B,\ A,\ E \]
