Utilizing Sub-Topic Units for Patent Prior-Art Search

One of the defining challenges in patent prior-art search is the problem of representing a long, technical document as a query. Previously work on this problem has concentrated on single query representations of the patent application. In the following paper, we describe an approach which uses multiple query representations generated from semantically coherent passages extracted from patent documents. We validate our technique in an experiment using the CLEF-IP 2011 patent search collection. Our system achieves statistically significant improvements over various state-of-art query generation techniques.

Graduation Project is a significant step for undergraduate students to practice their knowledge learned in universities. Due to many reasons, e.g., there are no tools to support total quality control process for the entire graduation project management, the completion quality of graduation project is not as good as the authorities expected. To address this issue, we implemented a graduation project management information system based on B/S model by using ASP & SqlServer to monitor, manage and control those which participate in the graduation project processes. It is driven by total quality control method and is supported by workflow technology. This system has been deployed and used in our department for 6 years. By this system, the management of graduation project becomes easy and efficient and the completion quality of graduation project as well as the graduation paper is improved a lot in our department. © 2010 IEEE.

A locking mechanism for distributed database systems

Journal of Networks 2014年第8期9卷 2211-2217页

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.

Trustworthiness plays an important role in service activities. However, it is not easy to define and compute the service trustworthiness as the evidence involves several information from different service party and maybe conflict at the same time. We discuss the definition and computation method of trustworthiness in this paper. The trustworthiness is acquired from service provider, service user, and service agent and then it is fused based on D-S evident theory. Finally, we testify that the trustworthiness can improve the precision of service discovery via simulation experiments. © 2010 IEEE.

With the explosive growth of data, how to apply these data with time characteristics to recommendation is particularly important. In order to do that, an attention-based time-aware neural collaborative filtering approach named ATNCF is proposed in this paper. Concretely, short-term preferences of users are learned by a time perception network, and long-term preferences part are modeled by a historical interaction matrix. Then, the short-term preferences are concatenated with long-term preferences as the dynamic user preference vector. After that, high-order user-item feature interactions are learned by a general neural collaborative filtering framework which includes two types of DL models, Deep Matrix Factorization (DMF) and Multiple-Layer Perception (MLP). Finally, the predicted scores are output from the final layer of AT-NCF. Experimental results on the real-world e-commerce dataset verify the effectiveness of the proposed method. © 2023 knowledge Systems Institute Graduate School. All rights reserved.

Web service discovery is an important problem in service-oriented computing with the increasing number of Web services. Clustering or classifying Web services according to their functionalities has been proved to be an effective way to Web service discovery. Recently, semantic-based Web services clustering exploits topic model to extract latent topic features of Web services description document to improve the accuracy of service clustering and discovery. However, most of them don’t consider deep and fine-grained level information of description document, such as the weight (importance) for each word or the word order. While the deep and fine-grained level information can be fully used to argument service clustering and discovery. To address this problem, we proposed a Web service discovery approach based on information gain theory and BiLSTM with attention mechanism. This method firstly obtains the effective words through information gain theory and then adds them to an attention-based BiLSTM neural network for Web service clustering. The comparative experiments are performed on ProgrammableWeb dataset, and the results show that a significant improvement is achieved for our proposed method, compared with baseline methods. © 2019, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.

Spiking neural P systems are a new class of bio-inspired computing devices incorporating the ideas of spiking neural networks into P systems. Homogeneous spiking neural P systems are a variant of spiking neural P systems, where each neuron has the same set of rules. The universality of homogeneous spiking neural P systems without delays is investigated and proved.

With the rapid development of Service-Oriented Architecture that enables rapid composition and integration of large-scale distributed systems, the number of web accessible services and their compositions is increasing rapidly, which makes it difficult to efficiently discover desired composite-services from a sea of candidates. Recently, topic-based clustering techniques have emerged as a promising way to improve the efficiency and accuracy of service discovery. However, it is a challenge to extract topics from short description texts of composite-services, for short texts do not provide sufficient word occurrences. In view of this problem, a multi-description topic based clustering approach for composite-service discovery is proposed. In this approach, descriptions of the component services of each composite-service are combined for topic extraction and modeling. Then, composite-services are clustered based on their topic similarities. Finally, composite-services are discovered from the cluster that is most topic-similar to the service queries. The effectiveness of the proposed approach was verified by some experiments on the real-world data at the end of this paper. © 2019 IEEE.

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.
