Based on the analysis of problems and difficulties in apparel quotation system, this paper puts forward the combination of BPM and SOA as a new idea for analysis of apparel quotation system, according to their advantages in business goals and requirements analysis, and the corresponding services' definition, extraction, optimization and integration. Through the combination, system flexibility, rapidity and accuracy could be achieved. The establishment of Service Repository according to the business requirements, is a crucial part in the architecture, however there are no definite rules for service extraction. In this paper, the detailed activities and steps, as well as a specific establishment case is illustrated. At last, architecture based on BPM and SOA for the apparel trade quotation is put forward, and its composition and implement are also analyzed.
Traditional web database cache techniques have a major disadvantage, namely poor data freshness, because they employ an asynchronous data refresh strategy. A novel web database cache, DB Façade, is proposed in th...

Ajax is an important approach for improving rich interactivity between Web server and end users during Web 2.0 eras. At the same time, the structured data in AJAX Web pages can not be extracted easily due to its asynchronous loading. In this paper, we propose a technique for extracting the structured data from the AJAX based Web pages. Firstly, an AjaxFetcher component is created to fetch the dynamic page content by using an embedded browser. Secondly, two different strategies are used to extract the structured data from the obtained page contents. Especially for the page that contains multi-records, an automatic approach to determine each possible record is proposed. Experimental results show that fetching Ajax pages and extracting the structured data from them is feasible.

Facing limitations of existing systems for process integrity measurement, we put forward a method with its prototype system PDIMS to measure process runtime integrity. Based on structure of process and format of executable file, PDIMS anatomizes the codepage layout of runtime process. Combining OS mechanisms and modern CPU's support for code execution, PDIMS catches and measures code page in the kernel when it executes. PDIMS depends on CPU's non-executable bit to detect code execution and on the binary format of executables of the process as criterion to verify code modifications in kernel. PDIMS provides trustworthy information about whether a running process is modified. PDIMS introduces less than 4% overhead to OS.

Nowadays mainstream RDF Repository Systems are based on RDBMS. The SPARQL query engine translates a SPARQL query into a SQL one, and then the RDBMS executes the SQL query. However the RDBMS optimizers, which usually assume that columns are statistically independent, often underestimate the selectivity of conjunctive predicates and choose a bad query execution plan. It is important for query optimizers to detect correlations among properties. We propose a way of computing property correlations based on ontology itself in order to improve the execution performance of the SQL translated from SPARQL statement queries.

One of the major limitations of current search engines is that users could not quickly locate what they want if the input query is too general. Some existing techniques try to cluster web search results into groups so as to user's quick browsing. In this paper, we present a new approach to categorize the web search results by using YAGO ontology. It utilizes the YAGO ontology to automatically generate categories for the user's specific query and classify the search results into appropriate categories. Our experimental results indicate that our method is feasible and effectiveness.
