This paper proposes a radial basis function (RBF) neural network algorithm based on factor analysis (FA-RBF) with the architecture feature of RBF network when the data are high-dimensional and complex. By reducing the feature dimension of the original data, FA-RBF algorithm regards the data after dimension reduction as the inputs of the RBF network, and then trains and simulates the network. The algorithm obviously simplifies the network architecture. By analyzing an example, the results show when the algorithm's predicted precision is not reduced, the convergence velocity is improved, the running time is saved and the error of the predicted value is reduced. In order to test and verify the validity of the new algorithm, we compare it with the RBF neural network algorithm based on principal component analysis (PCA-RBF), the predicted results of FA-RBF algorithm are better than the results of RBF and PCA-RBF algorithm. © 2010 IEEE.

This paper proposed an improved particle swarm optimization algorithm (IPSO) to solve continuous function optimization problems. Two improvement strategies named "Vector correction strategy" and "Jump out of local optimum strategy" were employed in our improved algorithm. The algorithm was tested using 25 newly proposed benchmark instances in Congress on Evolutionary Computation 2005 (CEC2005). The experimental results show that the search efficiency and the ability of jumping out from the local optimum of the IPSO have been significantly improved, and the improvement strategies are effective. © 2010 IFIP.

Data indexing is common in data mining when working with high-dimensional, large-scale data sets. Hadoop, a cloud computing project using the MapReduce framework in Java, has become of significant interest in distributed data mining. To resolve problems of globalization, random-write and duration in Hadoop, a data indexing approach on Hadoop using the Java Persistence API (JPA) is elaborated in the implementation of a KD-tree algorithm on Hadoop. An improved intersection algorithm for distributed data indexing on Hadoop is proposed, it performs O(M+logN), and is suitable for occasions of multiple intersections. We compare the data indexing algorithm on open dataset and synthetic dataset in a modest cloud environment. The results show the algorithms are feasible in large-scale data mining. © 2010 IFIP.

Combining the missing link: An incremental topic model of document content and hyperlink

The content and structure of linked information such as sets of web pages or research paper archives are dynamic and keep on changing. Even though different methods are proposed to exploit both the link structure and the content information, no existing approach can effectively deal with this evolution. We propose a novel joint model, called Link-IPLSI, to combine texts and links in a topic modeling framework incrementally. The model takes advantage of a novel link updating technique that can cope with dynamic changes of online document streams in a faster and scalable way. Furthermore, an adaptive asymmetric learning method is adopted to freely control the assignment of weights to terms and citations. Experimental results on two different sources of online information demonstrate the time saving strength of our method and indicate that our model leads to systematic improvements in the quality of classification. © 2010 IFIP.

Collaboration in agent grid based on dynamic description logics

The global expansion of the Web brings the global computing;and the increasing number of problems with increasing complexity & sophistication also makes collaboration desirable. In this paper, we presented a semantics-based framework for collaborative problem solving in agent grid by coupling joint intention and dynamic description logics (DDL), our previous work to extend description logics (DL) with a dynamic dimension to model the dynamic world. Capabilities and attitudes of agents were captured by actions, and formulas in DDL respectively. Thus representation components in our framework were conferred with well-defined semantics by relating them to some domain ontologies. We could employ reasoning on actions in DDL to help agents to find proper colleagues when collaboration is necessary, and the philosophy underlying Joint Intention to bind their actions to achieve their overall goal. The main strengths of our framework include: i) finding probably helpful agents in a semantically accurate way due to the employment of semantic information;ii) going much closer to industrial implementations while retaining the main express power of classical joint intention model. © 2010 IFIP.

Description logics are widely used to express structured data and provide reasoning facility to query and integrate data from different databases. This paper presents a many-sorted description logic MDL to represent relational databases. We give a translation from relational databases to the description logic MDL, and show this translation completely and faithfully captures the information in the relational database. Moreover, we show that some relational algebra operations could be expressed in MDL. © 2010 IFIP.

Requirement driven service composition: An ontology-based approach

作者： Cai, Guangjun Key Laboratory of Intelligent Information Processing Institute of Computing Technology Chinese Academy of Sciences Beijing 100190 China Graduate University of Chinese Academy of Sciences Beijing 100049 China

Service-oriented computing is a new computing paradigm that utilizes services as fundamental elements for developing applications. Service composition plays a very important role in it. This paper focuses on service composition triggered by service requirement. Here, the processes modeling the requirement should be treated in parallel with describing service and a same ontology should be adopted for allowing the understanding between the requirement and services. An effect-based approach has been proposed based on our previous work on service description. This approach could be promising for tackling the challenge of services composition. © 2010 IFIP.

Syntax-based statistical translation model is proved to be better than phrasebased model, especially for language pairs with very different syntax structures, such as Chinese and English. In this talk I will introduce a serial of statistical translation models based on source syntax structure. The tree-based model uses the one best syntax tree for translation. The forest-based model uses a compact forest which encodes exponential number of syntax trees in a polynomial spaces and lead to better performance. The joint parsing and translation model produces source parse trees, using the source side of the translation rules instead of separate parsing rules, and generate translations on the target side simultaneously, which outperforms the forest-based model. Some extensions of these models are introduced also. © 2010 by Qun Liu, Yang Liu, and Haitao Mi.

This paper illustrates the ICT Statistical Machine Translation system used in the evaluation campaign of the International Workshop on Spoken Language Translation 2010. We participate in the DIALOG tasks for Chinese-to-English and English-to-Chinese translation respectively. For both tasks, our system has achieved significant improvement with several effective methods as follows: 1) refining the data preprocessing, including Chinese word segmentation, named entity recognition, etc. 2) reducing the number of Out-of-Vocabulary(OOV) on the final test set by applying a fuzzy matching strategy. 3) considering generating a better input for the decoder from the N-best lists of ASR output as a special kind of translation task for the ASR task. 4) improving the performance of every single decoder, and reranking the n-best list for the final results submitted. © IWSLT 2010.
