人工智能与人类社会未来:挑战:人文视角陈斌北京大学gischen@〉对人的认知的冲击随着人工智能的发展,人们对自身的理解越来越物化和去意义化,人和机器的边界越来越模糊。
我们应该如何对待机器和自身的关系,人和机器是否应该整合?如何定义新的整合体?人有超越机器的东西吗?〉对人类思维的挑战机器人真的能模仿人类思维模式理解人的意图吗?〉深度学习可使机器高度模拟人的思维方式,不断学习。
AlphaGo深度学习两年就打败围棋世界冠军。
〉人工智能,正让人类渐渐失去学习的热情。
〉对人类社会结构的冲击人工智能一方面可以为解决贫困与不平等问题提供方案;另一方面也可能因为技术的壁垒将一部分人永久性地排斥在劳动力市场之外。
〉对人类心理的冲击机器人越来越聪明,我们有朝一日会被人工智能取代吗?〉人工智能可以推动进一步的专业分化和创造新的工作机会,但并非所有人都有能力迈过技术性和社会性的壁垒。
〉未来社会可能出现“无用阶级”,人对技术进步和快速经济社会转型所产生的“无用感”和“无力感”,会挫伤人的发展信心。
〉对隐私保护的冲击随着人工智能的发展,即使合法地获取和利用数据也会对隐私产生威胁,大数据技术揭示人的行为规律,使人前所未有地暴露在他人面前。
〉对经济市场的冲击迄今为止的经济学理论都是为物化的商品准备的,在人工智能介入知识经济时代后,经济规律将如何改写?在知识经济时代,有条件接触到大量数据的企业会拥有独特的竞争优势,这种垄断对于公共福祉的影响同样值得重视。
〉人类应如何看待人工智能的发展?人工智能一方面给我们带来极大的便捷与财富,另一方面又给我们带来许多社会焦虑。
技术的革新无法阻挡,与其逃避,不如解决问题〉总结:人工智能的发展是机遇也是挑战,挑战着我们的智力,也挑战着我们的心理,但新时代会以不可阻挡的趋势到来,我们要做的应是:克服恐惧,勇往直前!。

Introduction to Managing the HumanResourceName:YunZhao AnClass:Business Management 1NO:5920090283Date:April 6, 2011Beijing Institute of Technology1 Define human resource managementEffective development of human resources, reasonable configuration, full use and scientific management system, laws, procedures and methods of the sum of the Human Resource Management: The policies and practices involved in carrying out the “people” or human resource aspects of a management position ,inc luding: recruiting, screening, training, rewarding, and apprising.2. Describe how human resource management differs from personnel ManagementPersonal management(traditional approach) including Marginalised mangament function that is not seen as central to the business needs of the organisation but merely there to provide a welfare sevice to workers.Reactive role takes action to put in place policies and procedures in response to requestes from line mangers.Besides,Human resource management(new approach) is included as well that Strategic management function.There are 2 points,one is seen as key to the business needs of the organisation and involved in decision making at a strategic level. Recognises that the workers in an organisation are its most valuable asset.Another one is anticipates organisational needs and introduces innovative ideas,for example restructuring the whole organisation to increase communication between management and workers.3 In the evolution of personnel and human resource management, four major stages can be discerned social justice,human bureaucracy,consent by negotiation organisation and integration.Briefly describe the key developments in each of these stagesA:Human resource management as a distinct profession development can be traced back to the Industrial Revolution, factory establishment personnel department, researchstaff wages and welfare Personnel management policy of giving way to human resources personnel functions from the nineteenth century the work of social reformers appear. In the early factory workers facing extremely bad conditions, long working hours, and mostly living in slums. This soon caused riots in several workers, the Government will intervene to provide basic rights and protection of workers and the need to force the manufacturers to comply with the establishment of a formal mechanism to study the wages and benefits and other laws and regulations, and other remedies labor-related issues. This has led to personnel management as a unique industry appear. These workers, reformers criticized Robert Owen, Lord Shaftesbury, or exploitation.BIn the early 20th century, began to focus on human welfare and more areas, this period began large-scale enterprises. Human Resource Management aims to maximize the efficiency of the employees, so the organization should be the most effective way to use labor. Later, the rise of employee relations began to study the theory of social relations, staff morale and productivity is also affected an important factorC Consent by negotiationThe labor union history dates back to the guild system in Europe began, the purpose is to protect the status and choice of professional skills of the master control system. This is the beginning of how to form trade unions is how to combine large numbers of workers to create their own rules, not those set by their employer in the following section an example. This is ten?? Nineteenth century became the alliance, the National Labor Union, this is the first establishment of the National Union is very popular. This is the union how to start?? Exist. It all started as a great idea, and become what we see today. Although the agenda of today's Union may be changed, but the ideals and objectives are more or less unchanged. University courses began to personnel experts. The Government has set up a consulting service for employers to continue today's ACAS. Employee relations is an underlying philosoph, and the necessary attitudes and skills, rather than specific management functions and specificactivities. Union is its name implies - it is the people for the sake of their trade union. In other words, it is an organization of workers, wage increases in order to achieve some common goal, better working conditions, the Government established employers, ACAS advisory serviceD Organisation and integrationFrom around 1970, human and professionals to start building a relationship between organization and management more closely, not only deal with staff matters. Appeared at this time of recruitment, training these new areas of human expertise has also been progress, can be an example. Promotion of information technology to human. Sector development and change of personnel reasons: since the 1970s, the emergence of the law on employment, labor structure change. Layoffs and recruitment organizations, employment of women, as well as the emergence of part-time employees, technology development and the weakening of trade union rights4 What are the key functions of human resource management?Business transformation and change managementBusiness transformation and change management,which means Business transformation is a key executive management initiative[by whom?] that attempts to align an organisation's initiatives relating to people, process and technology more closely with its business strategy and vision. The initiative aims to support and help innovate new business strategies and to meet long-term objectives.Compensation and employee benefit management means Employee benefits and (especially in British English) benefits in kind (also called fringe benefits, perquisites, perqs or perks) are various non-wage compensations provided to employees in addition to their normal wages or salaries.[1] Where an employee exchanges (cash) wages for some other form of benefit, this is generally referred to as a 'salary sacrifice' or 'salary exchange' arrangement. In most countries, most kinds of employee benefits are taxable to at least some degreeTraining and development (learning management)In the field of human resource management, training and development is the field concerned with organizational activity aimed at bettering the performance of individuals and groups in organizational settings. It has been known by several names, including employee development, human resource development, and learning and development.There are some key fuction including Employee motivation and morale-building (employee retention and loyalty),Maintaining awareness of and compliance with local, state and federal labor laws,Recruitment, selection, and on boarding (resourcing) Employee recordkeeping and confidentiality。

We hope to see there!M ESSAGE FROM THE P ROGRAM C HAIRSSascha OssowskiUniversity Rey Juan Carlos, SpainRonaldo MenezesFlorida Institute of Technology, USAWelcome to the 22nd Symposium on Applied Computing (SAC 2007). Over the past 21 years, SAC has been an international forum for researchers and practitioners to present their findings and research results in the areas of computer applications and technology. The SAC 2007 Technical Program offers a wide range of tracks covering major areas of computer applications. Highly qualified referees with strong expertise and special interest in their respective research areas carefully reviewed the submitted papers. As part of the Technical Program, this year the Tutorial Program offers several half-day tutorials that were carefully selected from numerous proposals. Many thanks to Jaeyoung Choi from the Soongsil University and Tei-Wei Kuo from the National Taiwan University for chairing the Tutorial Program. Also, this is the fourth year for SAC to incorporate poster papers into the Technical Program. Many thanks to Mathew Palakal from Indiana University Purdue University for chairing the poster sessions. SAC 2007 would not be possible without contributions from members of the scientific community. As anyone can imagine, many people have dedicated tremendous time and effort over the period of 10 months to bring you an excellent program. The success of SAC 2007 relies on the effort and hard work of many volunteers. On behalf of the SAC 2007 Organizing Committee, we would like to take this opportunity to thank all of those who made this year's technical program a reality, including speakers, referees, track chairs, session chairs, presenters, and attendees. We also thank the local arrangement committee lead by Jiman Hong from the Kwangwoon University and Seong Tae Jhang from Suwon University. We also want to thank Hisham Haddad from Kennesaw State University for his excellent job again as the SAC Treasurer, Webmaster, and Registrar.SAC's open call for Track Proposals resulted in the submission of 47 track proposals. These proposals were carefully evaluated by the conference Executive Committee. Some proposals were rejected on the grounds of either not being appropriate for the areas that SAC covers traditionally or being of rather narrow and specialized nature. Some others tracks were merged to form a single track. Eventually, 38 tracks were established, which then went on to produce their own call for papers. In response to these calls, 786 papers were submitted, from which 256 papers were strongly recommended by the referees for acceptance and inclusion in the Conference Proceedings. This gives SAC 2007 an acceptance rate of 32.5% across all tracks. SAC is today one of the most popular and competitive conferences in the international field of applied computing.We hope you will enjoy the meeting and have the opportunity to exchange your ideas and make new friends. We also hope you will enjoy your stay in Seoul, Korea and take pleasure from the many entertainments and activities that the city and Korea has to offer. We look forward to your active participation in SAC 2008 when for the first time SAC will be hosted in South America, more specifically in Fortaleza, Brazil. We encourage you and your colleagues to submit your research findings to next year's technical program. Thank you for being part of SAC 2007, and we hope to see you in sunny Fortaleza, Brazil for SAC 2008.O THER A CTIVITIESReview Meeting: Sunday March 11, 2007, from 18:00 to 19:00 in Room 311A.

DB-IR integration becomes one of major challenges in the database area. Extensible architectures provided by commercial ORDBMS vendors can be used for DB-IR integration. Here, extensions are implemented using a high-level (typically, SQL-level) interface. We call this architecture loose-coupling. The advantage of loose-coupling is that it is easy to implement. But, it is not preferable for implementing new data types and operations in large databases when high performance is required. In this talk, we present a new DBMS architectureapplicable to DB-IR integration, which we call tight-coupling. In tight-coupling, new data types and operations are integrated into the core of the DBMS engine in the extensible type layer. Thus, they are incorporated as the "first-class citizens" within the DBMS architecture and are supported in a consistent manner with high performance. This tight-coupling architecture is being used to incorporate IR features and spatial database features into the Odysseus ORDBMS that has been under development at KAIST/AITrc for over 16 years. In this talk, we introduce Odysseus and explain its tightly-coupled IR features (U.S. patented in 2002). Then, we demonstrate excellence of tight-coupling by showing benchmark results. We have built a web search engine that is capable of managing 20~100 million web pages in a non-parallel configuration using Odysseus. This engine has been successfully tested in many commercial environments. In a parallel configuration, it is capable of managing billons of web pages. This work won the Best Demonstration Award from the IEEE ICDE conference held in Tokyo, Japan in April 2005.W EDNESDAY K EYNOTE A DDRESS The Evolution of Digital Evidence asa Forensic ScienceDr. Marc RogersChair of the Cyber Forensics Program,Department of Computer and InformationTechnology, Purdue University, USAW EDNESDAY M ARCH 14, 2007, 9:00 –10:00ROOMS 310 A, B AND CABSTRACTThe field of Digital Evidence while garnering significant attention by academia, the public, and the media, has really just begun its journey as a forensic science. Digital Forensic Science (DFS) in general is an immature discipline in comparison to the other more traditional forensic sciences such as latent fingerprint analysis. Digital Evidence, which falls under the larger umbrella of DFS, truly encompasses the notion of being an applied multi-disciplinary science. The areas of Computer Science, Technology, Engineering, Mathematics, Law, Sociology, Psychology, Criminal Justice etc. all have played and will continue to play a very large role in maturing and defining this scientific field. The presentation will look at the history of Digital Forensic Science and Digital Evidence, the current state of the field, and what might be in store for the future.S EOUL R EPRESENTATIVE A DDRESSKoran IT policy - IT839Dr. Jung-hee SongAssistant MayorChief of Information OfficerInformation System Planning DivisionSeoul Metropolitan Government, KoreaW EDNESDAY M ARCH 14, 2007, 18:30 – 19:00ROOMS 331-334(DURING BANQUET)ABSTRACTKorean IT policy initiated by Ministry of Information and Communication called IT839 Strategy will be introduced.

Combining Services and Semantics on the Web Katia Sycara,Massimo Paolucci and Naveen SrinivasanSoftware Agents LabCarnegie Mellon UniversityPittsburgh,PAMark BursteinHuman-Centered Systems GroupBBN TechnologiesCambridge,MAThe current Web is a collection of human readable pages that are virtu-ally unintelligible to computer programs.In recent years two parallel efforts emerged that have the potential of overcoming this limitation:thefirst ef-fort is the Semantic Web[1]which provides the tools for the explicit markup of the content of Web pages.The second effort aims to the development of Web services:self contained programs that by becoming the producers and consumers of information facilitate the automation of business transactions.The objective of the Semantic Web is to provide languages to express the content of Web pages and to make accessible to agents and computer programs the information that those pages contain.More precisely,the Se-mantic Web is based on a set of languages such as RDF and OWL that can be used to markup the content of Web pages.These languages have a well-defined semantics and a proof theory that allows agents to draw infer-ences over the statements of the language.As an example,an agent may use the semantic markup of the NOAA page reporting the weather conditions in Pittsburgh,and learn that the current condition is Heavy Snow;fur-thermore,the agent may infer from the semantic markup of the Pittsburgh school board page that in days of heavy snow all the schools are closed.By combining the two pieces of information,the agent would infer that indeed today Pittsburgh schools are closed.The second element of the Semantic Web is a set of ontologies,which provide a conceptual model to interpret the information provided.For ex-ample,an ontology of weather may contain concepts such as temperature,1snow,cloudy,sunny and so on.It may also contain information on the re-lation between the different terms;for instance,it may say that cloudy and sunny are two types of weather conditions.The vision of the Semantic Web is the transformation of the Web into an Internet wide knowledge representa-tion system,in which web pages provide information and ontologies provide the conceptual framework needed to interpret that information.However, while the Semantic Web provides meaning to the data represented on the Web,it still relies on static web pages,or ontologies,that always report the same information.Web services provide a way to disseminate information dynamically and on demand.There are many definitions of Web services.Here we adopt the definition in[2].“A Web service is a software system identified by a URI whose public interface and bindings are defined and described by XML.Its definition can be discovered by other software systems.These systems may then interact with the Web service in a manner prescribed by Internet protocols.”Despite the broad coverage of the Web services infrastructure and the amount of proposed interoperability standards,the emerging Web services infrastructure suffers from its dependence on pure XML for interoperation.XML guarantees syntactic interoperability which allows Web services to parse each others’messages but it is not enough for semantic understanding of the message content.As a result,Web services are left in the awkward state of identifying the pieces of information that they exchange,but they do not know how to interpret them.Because of its lack of explicit semantics,the Web services infrastructure is forced to assume that programmers hardcode the Web services interaction and the interpretation of the information that they exchange.Such hard-coding makes the implementation of the interaction and its maintenance very expensive.Any change in the description of a product,or the addition of a new product requires programmers to modify the code managing the interaction.Semantic interoperability is crucial for Web services.It allows Web services to(a)represent and reason about the task that a Web ser-vice performs(e.g.book selling,or credit card verification)so as to enable automated Web service discovery based on the explicit advertisement and description of service functionality,(b)explicitly express and reason about business relations and rules,(c)represent and reason about message order-ing,(d)understand the meaning of exchanged messages,(e)represent and reason about preconditions that are required to use the service and effects of having invoked the service,and(f)allow composition of Web services to achieve a more complex service.2The Semantic Web has the potential to provide the Web services in-frastructure with the semantic information that it needs.It could provide formal languages and ontologies to reason about service descriptions,mes-sage content,business rules and relations between these ontologies.In this way,the Semantic Web and Web services are synergistic:the Semantic Web transforms the Web into a repository of computer readable data,while Web services provide the tools for the automatic use of that data.The vision that we pursue is the realization of Semantic Web services, which result from the integration of semantic metadata,ontologies,formal tools and the Web services infrastructure.A Semantic Web service is a Web Service whose description is in a language that has well-defined semantics. Therefore,it is unambiguously computer interpretable,and facilitates max-imal automation and dynamism in Web service discovery,selection,compo-sition,negotiation,invocation,monitoring,management,recovery and com-pensation.Specifically,Semantic Web services rely on the Semantic Web to describe(1)the content of the messages that they exchange,(2)the order of the messages exchanged and(3)the state transitions that result from such exchanges.The result of using the Semantic Web is an unambiguous description of the interface of the Web service which is machine understand-able and provides the basis for a seamless interoperation among different services.The use of the Semantic Web to describe Web services has wide ranging consequences.It allows the description of additional properties of Web ser-vices,such as the quality of service and security constraints in a coherent and uniform way that is universally understood.Furthermore,and most im-portantly,the description of the states produced by the execution of the Web service is the basis for the description of its capabilities as a transformation from its inputs and preconditions,to its outputs and effects.Thefirst ontology for describing Web services is OWL-S[3].OWL-S attempts to close the gap between the Semantic Web and the Web services infrastructure.As ontology,OWL-S is based on OWL to define the concept of Web service within the Semantic Web.In addition it provides a language to describe actual Web services that can be discovered and then invoked using standards such as WSDL and SOAP.OWL-S uses the semantic an-notations and ontologies of the Semantic Web to relate the description of a Web service,with descriptions of its domain of operation.OWL-S adopts the view that the interaction of Web services requires three main operations:thefirst one is discovery of the providers on the ba-sis of their capabilities,the second one is the management of the interaction3on the basis of a partially specified protocol which describes the abstract information exchange between Web services andfinally the third operation is the transformation of the abstract information exchanges into message passing or remote procedure call.OWL-S therefore requires that Web ser-vices be represented by a specification of their capabilities,a representation of their interaction protocol and a specification of how to compile the actual messages to exchange.More precisely,a OWL-S Web service is defined as a OWL class with three properties which relate the Web service to the Service Profile,the Pro-cess Model,the Service Grounding.The Service Profile provides a represen-tation of the capabilities of the Web service in terms of the input/output transformation that it produces and of a set of non-functional parameters that specify availability,quality and other properties of the service.The Process Model provides a detailed view of process of the Web service from which the requester can derive the interaction protocol with the provider. Finally the Grounding maps the process model into a WSDL specification of how to interact with the Web service.OWL-S reliance on WSDL provides the bridge between the Semantic Web and the Web services infrastructure.The authors actively participated in the development of OWL-S,and developed algorithms and tools that favor interoperability across Web ser-vices.Such tools include capability-based matching on top of UDDI,au-tomatic Web service composition,ontology translation,and developement tools such as the OWL-S IDE.Our experience shows that any Semantic Web services language should be based on the following four principles:1.Web services should be represented by their capabilities and the resultsthat they produce.In turn this representation should allow means-end analysis and reasoning on what is the best Web service to achieve a given goal,and how to use that Web service achieve that goal.2.Any language to describe Web services should be independent of anyarchitectural design or implementation.Brokers and mediators should not be defined in the language,rather their capabilities should be descrivable in the language.3.The language should build on existing Web services standards:ratherthan defining a new set of languages to describe Web services.4.The language should build on existing Semantic Web standards,ratherthan on the“perfect logics”for Web services.Easy interoperability4with the semantic web is paramont to the success of any Semantic Web services language.The authors will engage in any W3C activity that would lead to stan-dardization of any aspect of Semantic Web services.References[1]Tim Berners-Lee,James Hendler,and Ora Lassila.The semantic web.Scientific American,284(5):34–43,2001.[2]David Booth,Michael Champion,Chris Ferris,Francis McCabe,Eric Newcomer,and David Orchard.Web services architecture./TR/2003/WD-ws-arch-20030514/,14May2003.W3C Working Draft.[3]OWL-S Coalition.Owl-s specification./services/owl-s/1.1/,2004.5。
