拥抱电商并购潮

作为一个创业者，连续15年的狂奔，我需要时间思考，把事情想透。所以过去的几个月，在京东高速发展的关键时期，我选择了去美国哥伦比亚大学游学。这期间，我关了微博、换了手机、专心学习，顺带减肥了36斤。     

借助能源央企总部，雍和园打造低碳示范园

放眼望去，北京东二环聚集着中石油、中石化、中海油、中国神华等大型能源央企总部和产业金融部门。“这些大型能源企业对新能源、节能减排等低碳产业的发展做出了巨大投入，它们是目前新能源经济重要的投资主体，也是未来温室气体排放量交易的重要参与者。央企优势资源的发挥，对引入新能源投融资主体，打造中关村雍和园低碳示范园，实现绿色金融的聚集发挥着重要的作用。”东城区区长杨艺文在2009年中关村论坛上表示。     

动画制作颠覆者胥克谦

曾有人问胥克谦,从钢琴老师跨界创业的距离有多远。胥克谦说,这种跨越花了他十几年的时间。然而这十几年,这个普通的老师却成了今天动画制作的颠覆者。2008年,马云的一句"如果银行不改变,我们就改变银行"让互联网金融如同雨后春笋般迅速崛起,之后,包括阿里、京东在内的电商已经开始抢银行的馒头;腾讯又以微信这款重量级产品让三大电信运营商心惊胆颤;传统行业昔日风光

Top排行榜2005年手机游戏十件大事

2005年即将逝去，回首过去的—年，我们体会的了手机游戏从幕后走入前台所经历的辛酸，我们亲历了game-V无线娱乐平台的发布，我们见证了手机网络游戏从试探到投入运营的全过程．也经历了手机游戏从无人问津到社会关注。也许2005年对于手机游戏注定是个不平凡的一年。因此，在这新旧交替的日子里，我们完全有必要对过往的一年作一个总结．于是，《2005年手机游戏十件大事》应运而生。     

An Advertising Strategy Using Consumption Externality and Forgetting in the Case of Japanese Electronic Books

We construct a two-period model in which a consumer recognizes the existence of goods after advertised by firms, and total sales of the first period affect the utility of each consumer’s purchase in the second period, indicating a consumption externality. Some consumers see advertisements in the first period and remember the product, whereas some forget the product in the second period. We show that the advertising volume changes given the differences in the forgetting rate. In particular, we apply our method to the data on Japan’s electronic books obtained through a conjoint analysis survey to clarify that a better strategy is to sell a product to a small number of people at a low price or to lower the price to a certain level during the early period, and then to sell the product to a specific consumer segment at a higher price after reflecting the externality.     

戴贫帽成“特大喜讯”是贫困县政策之耻

如果我们始终在用巨款去诱惑大家成为贫困县,把成为贫困县当做英雄一样地奖励,那么当然是贫困的地方要去抢,不贫困的地方弄虚作假也要去抢,一个地方甚至可以既是百强县又是贫困县。     

用创新、创业的方式反哺祖国母亲——记“2014海外赤子北京行”

当前北京加快转变经济发展方式,努力构建高精尖的经济结构,这为广大海外高层次人才都提供了机会,不断营造良好的创新创业环境,也将为海外人才来京发展提供全方位支持和保障。人才竞争是综合国力竞争的核心,人才资源作为经济社会发展第一资源的特征和作用也更加明显,谁能培养和吸引更多的优秀人才,谁就能在竞争中占据优势。从国际上看世界金融危机以来人才加速流动,一些国家纷纷修改法律,完善政策,出台措施,在引进留住人才上各显神通,这为我们提供了机遇也形成了巨大的挑战。     

Social Network Rebuilder: A Tool to Estimate a Social Network of Financial Crisis Propagation

The objective of this paper is to find a new method to estimate real social networks based on observed data collected by questionnaire surveys. Studies on social networks have been increasing in order to analyze social phenomena from a micro viewpoint. Most social phenomena can be explained by micro-level interactions among people. Spread of rumor and pandemics are typical example of micro interaction? However, there has not been much work on an analysis of real social networks based on observed data. This study tries to establish a methodology that exploits a genetic algorithm to rebuild a social network based on the data observed indirectly from real social networks. This paper introduces our proposed method, which allows us to rebuild a social network to some extent from degree distributions of a target real social network.

A Taxi Zoning Analysis Using Large-Scale Probe Data: A Case Study for Metropolitan Bangkok

Taxis are considered one of the most convenient means of transportation, especially when people have to travel off-route, where public transportation is not a feasible option, and also when they need to reach a destination according to what is most convenient for them. However, many issues exist about taxi services, such as the problems of passengers who are unable to get taxi service at the location of their choice, or problems concerning when they need the taxi service to arrive. These problems may be due to the unavailability of the taxi at that particular location or due to the taxi driver not wanting to provide service. A taxi driver may not want to provide service to a potential passenger, because they may have preferences on the direction and areas they want to go or because of the different types of service zoning. Understanding the behaviors of taxi drivers and the characteristics of the trip/travel might be helpful to solving such issues. In this study, we conducted an analysis from a questionnaire survey and large-scale taxi probe data to understand taxi service behavior, travel characteristics, and to discover taxi service zoning characteristics. As a result, four types of taxi service zones including isolated zones, interactive zones, special service zones, and target zones were encountered. Travel characteristics were calculated and analyzed at different criteria, such as weekdays, weekends, and various time windows in a single day. The result of these characteristics was explained according to their similarities and dissimilarities in each type of zone. The discovery of the different zones and their respective definitions might be a good initiative for further development of a policy for taxi drivers to provide better service for passengers.

Comments’ Extraction by User ID,Keywords, and Anchor Texts from the Thread of a Bulletin Board System

Bulletin Board Systems (BBSs) on the Web are used by many users posting comments on threads. Each thread carries a subject of discussion. Most users post comments related to a subject. However, unrelated comments are also posted. The unrelated comments distract users and diminish their understanding of the entire story of a thread. Comments unrelated to a subject have to be filtered automatically. This paper proposes a method that extracts comments related to a thread subject from a thread of BBS. The method extracts two types of comments: comments related to a thread subject (main comments), and comments related to main comments (sub-comments). The main comments are extracted by a user ID and keywords in the comments. The sub-comments are extracted by explicit and implicit anchor texts in the comments. We experimented with the proposed method and verified that comments extracted by the proposed method support participants in understanding the entire story of a thread.

Evaluation of a Multi-robot Cafe Based on Service Quality Dimensions

While AI applications are popular in many domains, they should work harmoniously with domain exerts and end users. Furthermore, to develop such harmonious AI applications, we need agile AI platforms for not only developers, but also domain experts. Currently, we have developed PRactical INTElligent aPplicationS (PRINTEPS), which is a user-centric platform to develop integrated intelligent applications. This paper reports on a multi-robot cafe as a practical application of PRINTEPS and evaluates its service quality at a university festival. It is not clear if robotic services are perceived as attractive and/or valuable, and how the concept of robotic services could lead to customer satisfaction. Therefore, the evaluation of the quality of such services is necessary to identify the key factors that could contribute to improving customer satisfaction. The purpose of this research is to identify key factors in improving customer satisfaction in robotic services by evaluating the service quality of the multi-robot cafe. We designed questionnaire items based on SERVQUAL which is one of the service quality evaluation measurement methods and conducted a questionnaire survey at a multi-robot cafe held at a university festival. From the collected data, we modeled and evaluated the relationship between service quality and customer satisfaction to identify key factors in robotic services using a Bayesian network. In addition, the experiment confirms the usefulness of PRINTEPS.
