Data exchange is the problem of finding an instance of a target schema,given an instance of a source schema and a specification of the relationship between the source and the target. In this paper,we look into the basic properties of XML data exchange in the presence of probabilistic *** requires rethinking the very basic concepts of traditional XML data exchange,such as solution,universal solution,and certain answers of target *** develop a framework for XML data exchange over probabilistic XML documents,and give a polynomial-time materializing algorithm that computes target probabilistic douments.

The problem of anomaly detection on time series is to predict whether a newly observed time series novel or normal,to a set of training time *** is very useful in many monitoring applications such as video surveillance and signal recognition. Based on some existing outlier detection algorithms,we propose an instance-based anomaly detection *** also propose a local instance summarization approach to reduce the number of distance computation of time series,so that abnormal time series can be efficiently *** show that the proposed algorithm achieves much better accuracy than the basic outlier detection *** is also very efficient for anomaly detection of time series.

Compared with classical SOA,autonomous web service(AWS) is emerging as a promising *** this approach,AWS is an autonomous service entity which can search for service *** this paper,we introduce a model of AWS aggregation driven by requirement and propose a service collect-select mechanism to optimally select web services. Experimental results show that this approach outperforms "First Come First Served" approach.

Respecting an interactive context involving multiple participants,dynamic characteristics of their activities will cause situations not faithfully described in a static *** particular,the goal that represents the meanings of activities (equally as changes on situations),is far beyond the scope of ontology languages,such as the ***,we formalize activities as a sequence of context changes for computing entities. Further,the Past-Linear Temporal Logic(Past-LTL) is proposed to formulate the temporal relationship within activities and complement reasoning for *** addition,we reduce the validation of OWL-based temporal formulae into checking the entailment in OWL.
