Please rephrase the passage and keep about the same length

The emerging social media with inherent capabilities seems to be gaining edge over comprehensiveness, diversity and wisdom, nevertheless its security and trustworthiness issues have also become increasingly serious, which need to be addressed urgently. The available studies mainly aim at both social media content and user security, including model, protocol, mechanism and algorithm. Unfortunately, there is a lack of investigating on effective and efficient evaluations and measurements for security and trustworthiness of various social media tools, platforms and applications, thus has effect on their further improvement and evolution. To address the challenge, this paper firstly made a survey on the state-of-the-art of social media networks security and trustworthiness particularly for the increasingly growing sophistication and variety of attacks as well as related intelligence applications. And then, we highlighted a new direction on evaluating and measuring those fundamental and underlying platforms, meanwhile proposing a hierarchical architecture for crowd evaluations based on signaling theory and crowd computing, which is essential for social media ecosystem. Finally, we conclude our work with several open issues and cutting-edge challenges.

Answer 1

Despite the fact that the emergence of the social media comes with increasing risks in security and privacy, the instrinsic capabilities of this platform is being more valued than wisdom, purview and multifariousness. This flaws need to be addressed immediately. Reseachers have studied thealgorithms, protocols, mechanisms and models for both user security and social media. However, there is no comprehensive or universal metric to measure the trustworthiness or security of a social media platforms, which has frustrated the positive evolution of these platforms, with their tools and applications. In order to deal with the challenge, this paper conducted a survey on the current benchmark social media networks trustworthiness and security features, in the light of new various sophisticated means of cyber attacks and nwely emerginf intelligent applications. Subsequently, we shed light on a new metric to evaluate fundamental, underlying platforms, and we propose a hierarchical schema to evaluate crowds from crowd computing and signalling theory, which we believe to be absolutely imperative to the social media environment. Finally, we conclude by discussing on several issues that are yet to be solved and some remaining challenges that will need cutting-edge inventions.
