Due to the rapid growth in both the number and diversity of Web services on the Internet, it becomes increasingly difficult for developer to find the desired and appropriate Web services for Mashup creation. Even if the existing approaches show improvements in Web APIs recommendation, it is still challenging to recommend Web APIs with high accuracy and good diversity. Some of them integrate functionality clustering and the quality of service to recommend Web APIs for Mashup creation, but do not consider the high-order composition interaction relationship among functionality information, quality attributes. In this paper, we propose a novel Web APIs recommendation method via integrating the functionality clustering of service and the quality of service. In this method, it firstly obtains the functionality clustering by using Doc2Vec to cluster the description document of Web APIs. Then, the deep factorization machine model is used to extract the multi-dimension quality attributes of service and mine the high-order composition interaction relationship between them. Finally, the comparative experiments are performed on ProgrammableWeb dataset and experimental results show that our method significantly improves the performance of Web API recommendation in term of precision, recall, purity, entropy, DCG and HMD.

Web service recommendation faces the following problems: large-scale number of Web services, the diversity of service categories, and the sparseness of service texts on the Internet. To this end, a Web service recommendation method that combines word embedding with topic models is proposed in this paper. Firstly, the English Wikipedia is used to construct a high-quality Word embedding model to obtain semantic similar words, and based on the DMM model, the GPU promotion strategy is integrated into the topic derivation process to obtain more effective service implied topics. Secondly, the obtained topic distribution vector is used to calculate the similarity. Multi-dimensional features such as similarity of Web APIs, similarity of Mashups, co-occurrence and popularity of Web APIs, are modeled by deep factorization machine to rank and predict Top-N Web APIs recommended set. Finally, experiments conducted on a real dataset, by comparing the proposed method with multiple existing Web service recommendation methods, show that the proposed approach achieves better performance.

Since the existing radio frequency identification(RFID) mutual authentication protocols encounter the challenges such as security risks, an improved Hash-based lightweight mutual authentication protocol is put forward. The proposed protocol exploits one-way Hash function, of the transmitted message and updating dynamic shared key, better overcome the security risks of RFID. In this protocol, database takes on numerous computations, while tag only executes simple XOR,JION and Hash operations. Through BAN logic formal security proof, security performance analysis,efficiency analysis, this protocol can make up for the denial of service attack, updating key and de-synchronization, which are exist in the same kind of RFID. Therefore, the proposed protocol suits large-scale and low-cost radio frequency identification(RFID) system.

To overcome the disadvantages of the traditional locking mechanism for Distributed Database Systems (DDBS), such as the low transaction concurrency and the high communication costs, this paper studies the traditional mechanism with Two-phase Locking (2PL) protocol, and redefines the lock types and their compatibility matrix in DDBS, designs the structure of the Lock Table, improves the lock policy and the lock algorithm. Those make up of a new locking mechanism for DDBS. The experimental results show that this mechanism can intensively control and flexibly manage the requirements for locks with improved 2PL protocol and multi-granularity locking, and effectively ensure serializing scheduling of transactions and decrease the costs of communications while locking. It obtains the better transaction concurrency than the traditional mechanism. © 2014 ACADEMY PUBLISHER.

Effective workflow scheduling can improve the performance of workflow systems. Based on our previous works related to supporting instance aspect handling in workflows, this paper further studies the time-cost trade-off optimization problem of grouping and scheduling multiple workflow activity instances with the objectives of minimum acitity instances' total dwelling time and minimum acitity instances' total cost under multiple constraints. Its mathematic model is constructed and a scheduling optimizatin algorithm named PACO-TC is proposed. The result of simulation experiment shows its effectiveness.

In this paper we propose a new kind of geometry driven subdivision scheme for curve interpolation. We use cubic Lagrange interpolatory polynomial to construct a new point, selecting parameters by accumulated chord length method. The new scheme is shape preserving. It can overcome the shortcoming of the initial four point subdivision scheme proposed. © (2013) Trans Tech Publications, Switzerland.

This paper proposes a new business model named social acquaintance network oriented group buying. It focuses on the social acquaintance networks of consumers and makes consumers as "sales agents" that can initialize transactions of group buying and acquire their acquaintances to join in. Two key technical problems it brought are identified and analyzed. To solve them, a collab.rative filtering based recommendation method and a workflow based execution framework are also proposed.

Traditional technologies for enterprise applications integration (EAI), such as CORBA and EJB/DCOM component or middleware, can not be handily extended in the systems for dynamic business requirements. To solve the problem, using the principle of service-oriented architecture (SOA), an EAI framework based on web services and its interfaces are designed. The framework is extensible to dynamic business requirement, and achieves well heterogeneous datum sharing and integration of application systems in enterprises. © 2012 Springer Science+Business Media B.V.

In this paper, chaos synchronization problem of the fractional order Coullet system in a master-slave pattern is investigated by using the nonlinear feedback control method. Suitable synchronization conditions are analyzed based on the Lyapunov stability theory. And the synchronization of commensurate order Coullet chaotic system of the base order 0.98 is implemented by virtue of the method. Numerical simulations are provided to verify the performance of the proposed controller. © 2012 IEEE.
