A novel method to measure the graph similarity is proposed, where the labels, in-degrees, and out-degrees of the vertices in the graph are comprehensively considered in order to conquer the high complexity and information loss in the measurement process. In this proposal, the graph is decomposed into a generalized tree and its similarity can be measured by computing the cost of the node sequence triples in the generalized tree. The proposed method decreases the computational complexity to O(n2) in comparison with the other available graph similarity methods. An example is provided to illustrate that the method is feasible and effective. © 2015 IEEE.

Magnetic resonance imaging(MRI) is a kind of imaging modality, which offers clearer images of soft tissues than computed tomography(CT). It is especially suitable for brain disease detection. It is beneficial to detect diseases automatically and accurately. We proposed a pathological brain detection method based on brain MR images and online sequential extreme learning machine. First, seven wavelet entropies(WE) were extracted from each brain MR image to form the feature vector. Then, an online sequential extreme learning machine(OS-ELM) was trained to differentiate pathological brains from the healthy *** experiment results over 132 brain MRIs showed that the proposed approach achieved a sensitivity of 93.51%, a specificity of 92.22%, and an overall accuracy of 93.33%,which suggested that our method is effective.

Topic modeling for large-scale text data

Frontiers of Information Technology & Electronic engineering 2015年第6期16卷 457-465页

作者： Xi-ming LI College of Computer Science and Technology Jilin University Changchun 130012 China MOE Key Laboratory of Symbolic Computation and Knowledge Engineering Jilin University Changchun 130012 China

This paper develops a novel online algorithm, namely moving average stochastic variational inference （MASVI）, which applies the results obtained by previous iterations to smooth out noisy natural gradients. We analyze the convergence property of the proposed algorithm and conduct a set of experiments on two large-scale collections that contain millions of documents. Experimental results indicate that in contrast to algorithms named ＇stochastic variational inference＇ and ＇SGRLD＇, our algorithm achieves a faster convergence rate and better performance.

One of the major problems of axiom pinpointing for incoherent terminologies is the precise positioning within the conflict axioms. In this paper we present a formal notion for the entailment-based axiom pinpointing of incoherent terminologies, where the parts of an axiom is defined by atomic entailment. Based on these concepts, we prove the one-to-many relationship between existing axiom pinpointing with the entailment-based axiom pinpointing. For its core task, calculating minimal unsatisfiable entailment, we provide algorithms for OWL DL terminologies using incremental strategy and Hitting Set Tree algorithm. The feasibility of our method is shown by case study and experiment evaluations.

Designment of E-R model based on RDF (S) 2

Designment of E-R model based on RDF (S)

2nd International Workshop on Semantic Technologies, IWOST 2015

作者： Gao, Xiangbin Ouyang, Dantong Ye, Yuxin College of Computer Science and Technology Jilin University Changchun130012 China Key Laboratory of Symbolic Computation and Knowledge Engineering of Ministry of Education Changchun130012 China

Based on the vast domain resources of RDF (S) on the web and SPARQL's powerful query ability, this article presents a new method of designment of E-R model. The steps for this design are: (1) Formu- lating SPARQL rules (including resource query rules and schema query rules) by the analysis of RDF (S)'s structure. (2) Parsing the optimal resource obtained through the query sentences. (3) Completing the de- signment by taking advantages of the translation from RDF (S) model to entity-relationship model in accordance with the content queried. The re- sults indicate that, the designment of E-R model based on RDF (S) could restore user real requirements of great possibilities and help database de- signer to complete design in a strange area.

In previous studies, non-distance-dependent surveillance strategies have improved the performance of contagious outbreaks detection. In this paper, we propose a new distance-dependent strategy that does not require ascertainment of global or local network structure, namely, simply monitoring the relative significance difference of randomly selected individuals in school and workplace. To evaluate whether such two group could indeed provide early detection, we studied a flu outbreak in contact network simulation experiments. Our experimental results show that this method could provide significant additional time to react to epidemics, especially when the infection rate is not large.

The multilevel relational data model based on trust-label semantics

引用

Journal of computational Information Systems 2015年第11期11卷 3949-3956页

作者： Chen, Pan Wang, Limin Key Laboratory of Symbolic Computation and Knowledge Engineering of Ministry of Education Jilin University Jilin China State Key Laboratory of Computer Science Beijing China

As a new research direction in the field of database security, the technology of multilevel secure database is advancing by leaps and bounds. There are so many great multilevel secure relational models such as Bell-Lapadula model, SeaView model, Jajodia-Sandhu model and Smith-Winslett model in the last 40 years, which have solved or mitigated a lot of problems in this field with their own ways. But each of them still has one or several problems such as covert channels, semantic ambiguity, proliferation of tuples and poor expressiveness for complex situations. In this paper, we attempt to build a new model named TL model which could resolve as many problems as possible independently and retain the simpleness and expressiveness at the same time. We will clarify the TL model and present its simplicity, power and robustness. ©, 2015, Binary Information Press. All right reserved.

Research on collaborative filtering recommendation based on k-means clustering

In accordance with the inaccuracy of searching neighbors in traditional collaborative filtering algorithms, we narrow down the space of neighbor searching by means of partition clustering to improve the real-time performance of recommendations. Then by taking the similarity measurement into consideration, we convert the high-dimensional sparse matrix of user rating to the low-dimensional dense matrix of user interest to enhance the accuracy of recommendations. Experiments proved that combining the partition clustering based on user interests and collaborative filters could contribute to increasing real-time speed and the accuracy of recommendation effectively. © 2016 ICIC International.
