Event co-reference resolution is an important task in natural language processing, and nearly all the existing approaches for this task rely on event argument information. However, these methods tend to suffer from error propagation from event argument extraction. Additionally, not every event mention contains all arguments of an event, and the argument information may confuse the model where events contain arguments to detect an event co-reference in real text. Furthermore, the context information of an event is useful to infer the co-reference between events. Thus, to reduce the errors propagated from event argument extraction and use context information effectively, we propose a multi-loss neural network model that does not require any argument information relating to the within-document event co-reference resolution task; furthermore, it achieves a significantly better performance than the state-of-the-art methods.

Telecare Medical Information System(TMIS) can provide various telemedicine services to patients. However, information is communicated over an open channel. An attacker may intercept, replay, or modify this information. Therefore, many authentication schemes are proposed to provide secure communication for TMIS. Recently, Yu et al proposed a privacy-preserving authentication scheme in the Internet of Medical Things(IoMT)-enabled TMIS environments. They emphasize that their scheme is resistant to various attacks and ensures anonymity. Unfortunately, this paper demonstrates that Yu et al's scheme is vulnerable to impersonation attacks, replay attacks, and tracking attacks and cannot mutually authenticate. To overcome the shortcomings of Yu et al's scheme, we mainly improve the authentication and key agreement process and propose a corresponding improved scheme. We also compare the improved scheme with several existing authentication schemes in terms of security and computational efficiency.

Nowadays, Internet of Everything has become a major trend, and Internet of Things(IoT) has emerged. Wireless sensor networks(WSNs) are core technologies for IoT to sense the real world. Due to the unattended and resource-constrained characteristics of WSNs, it is a great challenge to design an efficient and secure authentication scheme for communication between users and sensor nodes in WSNs. Recently, Hu et al proposed an authentication scheme for WSNs in an IoT environment. They claimed that their scheme could maximize the balance between security and computational cost as well as efficiency, and be resistant to many known attacks. However, we find that the scheme is difficult to resist stolen smart card attack and denial-of-service attack. Moreover, during the login and key negotiation phase of the scheme, Gateway(GWN) is unable to extract key values for subsequent computation based on the messages sent by the sensor nodes, which in turn leads to the inability to achieve mutual authentication and key agreement. To overcome these shortcomings, we propose an improved scheme. The proposed scheme enables real-time data exchange and transmission as well as secure communication between users and sensor nodes.
