From query log to competitive advertising: A business intelligence method for elaborating consideration set of keywords 从查询日志到竞争广告:一种用于详细描述关键字考虑集的商业智能方法
Wei Ying, Wei Qiang, Zhang Jin
With the rapid development of keyword advertising on search engine platforms, competitive advertising becomes a novel strategy for advertisers to gain more potential market share. Though keyword suggestion methods can help match the keywords chosen by the advertisers and the queries in search engine, mainstream keyword suggestion methods suggest keywords by directly extending seed keywords and cannot support competitive keyword advertising effectively, which can further help advertisers understand the competitive intelligence from search engine users' intention and adopt an competitive advertising strategy to seize competitive advantage. This paper proposes a notion of competitive keyword as well as competitiveness in keyword advertising. Moreover, a novel competitive keyword suggestion method, namely CompKey, is designed to help advertiser find more appropriately competitive keywords based on query log without incorporating further exogenous knowledge, e.g., webpage contents or semantic hierarchy. Furthermore, analyses on two real world cases show the benefits and effectiveness of the proposed notion and the CompKey method.
随着关键词广告在搜索引擎平台上的快速发展,竞争广告成为广告主获取更多潜在市场份额的新策略。关键词建议方法虽然可以帮助广告主选择的关键词与搜索引擎中的查询进行匹配,但主流的关键词建议方法是通过直接扩展种子关键词来提出关键词,不能有效地支持竞争性关键词广告,这可以进一步帮助广告主从搜索引擎用户的意图中了解竞争情报,采取竞争性广告策略,抢占竞争优势。本文提出了竞争性关键词的概念以及关键词广告的竞争力。此外,我们还设计了一种新的竞争性关键词建议方法CompKey,它可以帮助广告主在不考虑网页内容或语义层次等外生知识的情况下,根据查询日志找到更合适的竞争性关键词。此外,对两个实际案例的分析表明了所提出的概念和CompKey方法的优点和有效性。

Structural equation modeling combined with extension method for evaluating factors affecting location selection of proposed senior daycare facilities 结合可拓法的结构方程模型评价老年日托设施选址影响因素
Ku Mei-Yu, Ding Pei-Yu, Liu Che-Kai, Sung Meng-Yuan, Lin Chien-Liang
With the tendency of population aging continues in our nation, problems associated with the elderly become major concerns in our society. If daycare centers for seniors can be established to care for the elderly just like daycare facilities for caring pre-school age children, seniors will have a place to enjoy day-time activities and return home to enjoy normal family life. The senior center that allows seniors to enjoyable their remaining years with dignity will be a demanding neighborhood facility. However, the location of such a facility is of great importance for its acceptance by the general public; a location that pleases seniors and their family is expected by all involved. The senior daycare center is a fixed and permanent facility; its location is also the key to affect the return of investors. A properly selected location will maximize the economic benefit while lowering the risks associated with the investment. Hence, in this research, the CFA (Confirmatory Factor Analysis) available in SEM (Structural Equation Modeling) is applied to evaluate important factors that affect the selection of senior daycare center and the degree of suitability for implementing the model to conduct such evaluations. The results on selecting the most appropriate location for establishing a senior daycare center are verified with case study data using the extension method. The combination of structural equation modeling and extension method leads to results that comfort to model evaluation indices when the suitability of individual models and the overall modeling are concerned. Using the extension method allows one to find the most appropriate location based on case study information. This proves that the method implemented in this research is capable of solving problems that are contradictory and incompatible in nature.
随着我国人口老龄化趋势的持续,与老年人有关的问题成为我们社会关注的主要问题。如果可以像照顾学龄前儿童的日托设施一样,建立照顾老年人的日托中心,老年人就有地方享受白天的活动,回到家中享受正常的家庭生活。让老年人有尊严地度过余生的老年中心将是一个要求很高的社区设施。然而,这种设施的位置对公众的接受程度至关重要;一个让老年人和他们的家人满意的地方是所有参与者所期望的。老年人日托中心是固定的、永久性的设施;其选址也是影响投资者回报的关键。一个合适的选址将使经济效益最大化,同时降低与投资相关的风险。因此,本研究运用结构方程模型(SEM)中的验证性因子分析(Confirmatory Factor Analysis, CFA)来评估影响老年人日托中心选择的重要因素以及实施模型的适合度。运用扩展法,通过案例研究数据验证了老年日托中心选址的结果。将结构方程建模与可拓方法相结合,可以使模型评价指标在个体模型适用性和整体模型适用性方面得到较好的结果。使用扩展方法可以根据案例研究信息找到最合适的位置。这证明了本研究中采用的方法能够解决本质上矛盾和不相容的问题。

Study on the participating strategy of China in the international energy security cooperation 中国参与国际能源安全合作战略研究
Zhao Shu-rong, Chen Shao-pei
Energy security is a global and comprehensive issue. As the establishment and development of international energy market, the previous thinking model of ensuring energy security by restricting on supply of energy has been changed. The research in this field has shifted to the establishment of mechanisms such as cooperation or pricing mechanism by which, policies of different countries can be coordinated; self-sufficiency of each country in energy supply will be improved; common energy saving measures may be adopted and the information of the international energy market can be shared by all and etc. This paper, by understanding of the new situation of international energy security, learning from international experiences and combining with China's own feature, aims at analyzing the new situation encountered by China in the field of energy security from the perspective of international cooperation, generalizing and concluding the status quo, its problems and challenges facing China so as to to present participating strategy of China in the international cooperation of energy security, such as promoting the establishment of energy security mechanism of China in the context of international cooperation, enhancing bilateral cooperation mechanism and international cooperation in low-carbon and clean energy.
能源安全是一个全球性、综合性问题。随着国际能源市场的建立和发展,以往通过限制能源供应来保障能源安全的思维模式发生了变化。该领域的研究已转向建立合作或定价机制等机制,以协调不同国家的政策;各国能源供应的自给能力将得到提高;可以采取共同的节能措施,可以共享国际能源市场的信息等。本文通过对国际能源安全新形势的认识,借鉴国际经验,结合中国自身特点,旨在从国际合作的角度分析中国在能源安全领域面临的新形势,归纳总结中国在能源安全领域的现状、面临的问题和挑战,提出中国参与能源安全国际合作的战略。例如,在国际合作背景下推动中国能源安全机制的建立,加强双边合作机制和国际低碳清洁能源合作。

Research on BDS pricing with variable structure of default correlation 基于违约相关变结构的BDS定价研究
Liu Xiang-hua, Xiao Xue-ping
The pricing of CDS has become a hot issue after the U.S. subprime mortgage crisis erupted. For BDS with different reference assets, it is important to define the default correlation between the assets. Using copula functions to describe the dependent structure between the assets has some advantages and becomes popular recently. In the paper, we develop a BDS pricing model using the copula function with variable structure to describe default correlation. Considering the influence of economy situation change on BDS pricing, we introduce the Markovian regime shift to default density and default correlation change along with economy situation and make comparison by Monte Carlo simulation. The study finds that the BDS price obtained from the model with variable structure is located between BDS prices from the model without variable structure under different initial conditions. As default density is directly proportional to BDS price and default correlation is inversely proportional to BDS price, the influence of economy situation change on BDS pricing results from the comprehensive effect of default density and default correlation. Generally speaking, the influence of default density will exceed that of default correlation, thus, the BDS price in times of prosperity is low than that in times of depression.
美国次贷危机爆发后,CDS的定价成为一个热点问题。对于具有不同参考资产的BDS,重要的是定义资产之间的默认相关性。用联结函数来描述资产间的依赖结构具有一定的优势,是近年来比较流行的一种方法。本文利用变结构的copula函数来描述默认相关性,建立了北斗系统定价模型。考虑到经济形势变化对BDS定价的影响,我们引入马尔可夫政权转移到违约密度和违约相关性随经济形势的变化,并通过蒙特卡罗模拟进行比较。研究发现,在不同初始条件下,由变结构模型得到的BDS价格位于无变结构模型得到的BDS价格之间。由于违约密度与北斗价格成正比,违约关联度与北斗价格成反比,因此经济形势变化对北斗定价的影响是违约密度和违约关联度综合作用的结果。一般来说,违约密度的影响会超过违约相关性的影响,因此,繁荣时期的BDS价格低于萧条时期的价格。

MS-AR model based dynamic identification of RMB appreciation pressure 基于MS-AR模型的人民币升值压力动态识别
Ye Xin
It has practical significance to the effective identification and dynamic assessment of RMB appreciation pressure. In this study nonlinear MS-AR model with the assumption that residual obeys T distribution is used to do empirical analysis on the spot exchange rate of RMB/USD in the period of 2005.7.22-2012.12.12. The results show that there are three regimes including appreciation with high volatility, appreciation with low volatility and stability with small depreciation. Appreciation with high volatility appeared after two RMB exchange rate regime reforms, which indicates that exchange rate regime reform released partial pressure of RMB appreciation. Appreciation with low volatility was found in the period of America subprime crisis, because People's Bank of China narrowed exchange rate fluctuation region. Stability with small depreciation witnessed that the outbreak of sovereign debt crisis in European countries, that increased the demand for USD, in turn led to the small depreciation of RMB. All the above results demonstrate that the accumulated period and dynamic change characteristics of RMB appreciation pressure.
这对有效识别和动态评估人民币升值压力具有现实意义。本文采用假设残差服从T分布的非线性MS-AR模型对2005.7.22-2012.12.12期间人民币兑美元即期汇率进行实证分析。结果表明,人民币汇率存在高波动的升值机制、低波动的升值机制和小贬值的稳定机制。两次人民币汇率形成机制改革后出现了高波动性的升值,说明汇率形成机制改革释放了人民币升值的部分压力。在美国次贷危机期间,由于中国人民银行收窄了汇率波动区域,出现了低波动性的升值。稳定,小幅贬值,欧洲国家主权债务危机爆发,美元需求增加,导致人民币小幅贬值。以上结果表明了人民币升值压力的阶段性积累和动态变化特征。

Also we analyze the mutual influences of the intellectual property rights and open business mode, and put forward to connect intellectual property rights and open business model and build open business model based on intellectual property rights(IPR). Finally we give a successful case analysis, and hope this paper can have certain significances on the innovation of corporation business model.","PeriodicalId":339946,"journal":{"name":"2013 International Conference on Management Science and Engineering 20th Annual Conference Proceedings","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124955596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A method and application to index design and decision making based on Takagi-Sugeno fuzzy inference 基于Takagi-Sugeno模糊推理的指标设计与决策方法及应用
Ma Xue-jun, Zhang Huai-qiang
In order to find the optimal solution among contradictory objectives, an aggregation method for the objectives based on Takagi-Sugeno fuzzy inference was proposed. By establishing membership functions and fuzzy rules, this method could express decision makers' preference structure more accurately. The fuzzy inference aggregation method for the objectives is closer to the actual decision-making process and overcomes the limitation of a specific function form, so it has a better approximation characteristic than traditional aggregation methods. An example was showed to illuminate the method and decision-making process.
为了在相互矛盾的目标之间寻找最优解,提出了一种基于Takagi-Sugeno模糊推理的目标聚合方法。该方法通过建立隶属函数和模糊规则,能更准确地表达决策者的偏好结构。针对目标的模糊推理聚合方法更接近实际决策过程,克服了特定函数形式的限制,因此比传统的聚合方法具有更好的逼近特性。通过实例说明了该方法和决策过程。
