Tie strength in question answer on social network sites
1.How do the authors define strong and weak ties, and how did they measure the strength of a tie in Social Network Sites?
Strong and weak bonds are both relevant and important in interactions with social networks. They perform different functions in relationships but can extend the network well beyond the normal range. Using and maintaining socially weak bonds can bring far-reaching benefits outside of normal relationships.
Measuring tie strength:
Days since last communication
Days since first communication
Words exchanged
Mean ties strength of mutual friends
Positive emotion words
Intimacy words
2.What could be the reasons that more helpful answers come from weak ties? What could be the reasons that more helpful answers come from strong ties?
Strong ties will probably go through great length and spend a lot of time to help you. But since you only have few strong ties, they might not be able to get helpful answers. In contrast, your acquaintances (weak ties) will probably spend only a few minutes to forward your question to their human resources.
3.As participants were especially looking for reliable information, how could reliability of the information source be measured in Social Networks?
There are some ways to measure the reliability of the information source in Social Networks:
Knowledge on the topic: Its means how informative the answer and contributed to overall knowledge.
Ties Strength and Overall Knowledge: Its means how much does this answer contribute to your overall knowledge.
Ties Strength and Value: How much participants trust specific answers is correlated Positively with tie strength.
Ties Strength and Already Known Information: Friends with wildly different tie strengths.
Games with a Purpose (GWAP)
-
Which mechanisms do the games include that motivate people to “think alike”?
As the games are directly related to human psychological needs and behavioral patterns, they are becoming powerful tools for achieving goals. Online games are such a method for encouraging people to participate in the process. Such games constitute a general mechanism for using brain power to solve open problems.
“Games with a purpose” have a vast range of applications in areas as diverse as security, computer vision, Internet accessibility, adult content filtering, and Internet search. Two such games under development at Carnegie Mellon University, the ESP Game, and Peekaboom demonstrate how humans, as they play, can solve problems that computers can’t yet solve.
Mechanisms do the games include that motivate people to “think alike” combined using the following two principles:
Define difficult but achievable tasks: Game offers many short-term goals, achievable, to maintain commitment.
Define clear objectives and game rules: Game provides clear objectives and well-defined rules of play to ensure that players feel empowered to achieve goals.
While the concept of Games with a Purpose (GWAP) can be simple, consists of goals, actions, tokens, feedback, a rule system, challenge, and the user’s skill with the following meaning attached to them. Goals express a certain game state the player wants to achieve. Actions determine what a player can perform to approach his goals. Tokens describe the entities a player can act upon; their configuration represents the game state. Rules refer to the algorithms determining the effects of the player’s actions on the game state. Feedback stands for information by which the game informs the player of its current state in response to his actions. Challenge refers to the central skill that has to be mastered.

According to this website, (Ajapaik.ee) explore the history of the neighborhood and rephotograph the views for the future generations, and allows you to see the change throughout the time.
Recognize the old photos and place them on the map where you think they have been taken. How many photos can you locate? The closer you get to the correct vantage point the more points you earn. Get extra points for reshooting the view. This is a basic puzzle game.
