I am a student of MS(CS) & needs answers about my research topic. Topic is about "Computing effectiveness of Online social networks and search engines in academic searching". Guide me with your experience.
Your question is, from my point of view, quite broad... You could be also more precise in the description. For example, what does "effectiveness" refer to in your subject?
However, if I can try a guess from your question description, your topic seems related to Information Retrieval and Social Network Analysis. This could be a good start for you to dig in...
