Furthermore, a search system of thun-derstorm in history was established, laying foundation for prevention and prepared-ness of thunderstorm in Anyang.

Continuous query scheduler based on operators clustering

Data stream management system (DSMS) provides convenient solutions to the problem of processing continuous queries on data streams.Previous approaches for scheduling these queries and their operators assume that each operator runs in separate thread or all operators combine in one query plan and run in a single thread.Both approaches suffer from severe drawbacks concerning the thread overhead and the stalls due to expensive operators.To overcome these drawbacks,a novel approach called clustered operators scheduling (COS) is proposed that adaptively clusters operators of the query plan into a number of groups based on their selectivity and computing cost using S-mean clustering.Experimental evaluation is provided to demonstrate the potential benefits of COS scheduling over the other scheduling strategies.COS can provide adaptive,flexible,reliable,scalable and robust design for continuous query processor.

Probabilistic Top-k Query:Model and Application on Web Traffic Analysis

Top-k ranking of websites according to traffic volume is important for Internet Service Providers(ISPs) to understand network status and optimize network resources. However, the ranking result always has a big deviation with actual rank for the existence of unknown web traffic, which cannot be identified accurately under current techniques. In this paper, we introduce a novel method to approximate the actual rank. This method associates unknown web traffic with websites according to statistical probabilities. Then, we construct a probabilistic top-k query model to rank websites. We conduct several experiments by using real HTTP traffic traces collected from a commercial ISP covering an entire city in northern China. Experimental results show that the proposed techniques can reduce the deviation existing between the ground truth and the ranking results vastly. In addition, we find that the websites providing video service have higher ratio of unknown IP as well as higher ratio of unknown traffic than the websites providing text web page service. Specifically, we find that the top-3 video websites have more than 90% of unknown web traffic. All these findings are helpful for ISPs understanding network status and deploying Content Distributed Network(CDN).

Querying on Wang Xiaolu＇s Estimation on Grey Income in China1

This paper believes that serious flaws exist in Wang Xiaolu＇s calculation of grey income in China for the following reasons.＂ （1） It is not sound methodology to match households with different income levels by using Engel coefficients; （2） The way Wang collected data cannot make up for statistical distortion in the National Bureau of Statistics＇ data; （3） Wang did not provide reasonable explanations for both the income inequality as derived from the estimated income groups and the change in income inequality between the two years he compared,＂ （4）Wang＇s calculation of grey income lacks a basic logical foundation.

Query Expansion Using Wikipedia and a Concept Base in Cross-language Information Retrieval

The present paper describes the use of online free language resources for translating and expanding queries in CLIR （cross-language information retrieval）. In a previous study, we proposed method queries that were translated by two machine translation systems on the Language Gridem. The queries were then expanded using an online dictionary to translate compound words or word phrases. A concept base was used to compare back translation words with the original query in order to delete mistranslated words. In order to evaluate the proposed method, we constructed a CLIR system and used the science documents of the NTCIR1 dataset. The proposed method achieved high precision. However~ proper nouns （names of people and places） appear infrequently in science documents. In information retrieval, proper nouns present unique problems. Since proper nouns are usually unknown words, they are difficult to find in monolingual dictionaries, not to mention bilingual dictionaries. Furthermore, the initial query of the user is not always the best description of the desired information. In order to solve this problem, and to create a better query representation, query expansion is often proposed as a solution. Wikipedia was used to translate compound words or word phrases. It was also used to expand queries together with a concept base. The NTCIRI and NTCIR 6 datasets were used to evaluate the proposed method. In the proposed method, the CLIR system was implemented with a high rate of precision. The proposed syst had a higher ranking than the NTCIRI and NTCIR6 participation systems.

Improved caching policies and hybrid strategy for query result cache

To improve efficiency of search engines, the query result cache has drawn much attention re- cently. According to the query processing and user＇s query logs locality, a new hybrid result cache strategy which associates with caching heat and worth is proposed to compute cache score in accord- ance with cost-aware strategies. Exactly, query repeated distance and query length factor are utilized to improve the static result policy, and the dynamic policy is adjusted by the caching worth. The hy- brid result cache is implemented in term of the document content and document ids （docIds） se- quence. Based on a score format and the new hybrid structure, an initial algorithm and a new rou- ting algorithm are designed for result cache. Experiments＇ results show that the improved caching policies decrease the average response time effectively, and increase the system throughput signifi- cantly. By choosing comfortable combination of page cache and docIds cache, the new hybrid cac- hing strategy almost reduces more than 20% of the only cache and docId-only cache. average query time compared with the basic page-

Application of Traditional Chinese Medicine in medical practice：a survey of community residents in Beijing,China

OBJECTIVE:To investigate how community residents in Beijing understood and used Traditional Chinese Medicine(TCM) in their medical practice.METHODS:This was a cross-sectional study conducted on 3410 community residents from four large communities of Tongzhou district in Beijng,China.A validated, self-administered questionnaire comprised of three sections was used to gather the data.A systematic sampling procedure was applied to recruit the community residents.RESULTS:A total of 3410 participants completed the questionnaire survey.It showed that in highly educated residents, 33.4%(170) knew of the names of 3-10 Chinese herbals, 35.8%(182) knew of names of 3-10 traditional Chinese patent drug.Among all the respondent residents, 80.7%(2753)believed that TCM herbal therapy and TCM non-drug treatments were effective in disease treatment, health enhancement, 85.7%(2923) had taken traditional Chinese patent drug in their life,56.8%(1937) of residents had used herbal decoction, 40.0%(1365) had received non-drug treatment of TCM, such as acupuncture, massage, cupping, auricular acupuncture.Among the elderly residents, 11.4%(98) often used Chinese patent drug and 9.8%(85) often used herbal decoction.In addition, 70.8%(2415) of residents were willing to accept knowledge and information on TCM for health enhancement and disease prevention, such as medicated diet, medicinal tea, Tai Chi and Qi Gong, although 82.8%(2825) of residents had never used them.CONCLUSION:Chinese patent drug and herbal decoction are widely used in the communities in Beijing, and there existed a possible close correlation between high educational level and better understanding of TCM.Age and occupation also correlated with the attitude to TCM therapies.The characteristics of the residents should be considered seriously in the course of promoting the understanding and application of TCM.

ANALYSIS OF A PRODUCTION-INVENTORY MODEL WITH ERLANGIAN DEMAND ARRIVAL PROCESS

We study a production-inventory system having a machine, a storage facility. The demand for the product is governed by an Erlangian demand arrival process, where demand sizes are independent and identically distributed random variables. A two-criticalnumber policy (m, M) is used to control a machine's setups and shutdowns, namely, a machine is shut down whenever the inventory level reaches M, and resumes operating only when the inventory level falls below the critical number m(m ≤ M). We obtain the steady state distribution of the inventory process and some performance measures of the process.
