Royal Society Web Science meeting

30.09.2010

It was one of a series of seminars, organized by the Royal Society of Science, as part of the celebration of 350 anniversary of the society. It was an academic group with the participation of the stars and the scientific community web Tim Berners-Lee.

Web science is a new discipline of science, has recently been established and defined by the 2006th. Initial activities of academics regarding the use of science in the broadest sense, the use of analytical and mathematical models to understand the mechanics of the Internet, the web as engineering design, shape and structure of the web, social models that govern the Internet, the diversity and dynamic nature of links and web content.
Important field of action is "collective intelligence", which best reflect Winipedia and Galaxy Zoo. Science on the Web encourages transparency in government and citizen contacts with legislators, using the Web.

Albert-Lazlo Barabasi spoke of the scientific community that supports and depends on many aspects of science on the web such as networks of computers via cables, nodes, hyperlinks, and a network of people and an organization. He spoke of the earliest mathematical models of complex networks, which date from the Erdos-Reny model in 1960. Speaking of networks, introduced the www as a network with a trillion documents 1999th and like its not a random structure, which is therefore suitable for mathematical analysis.
The network has no measure, no single point that represents the whole. Preference principle works, so that people prefer to bind to the attractive points / addresses, which have more connections and more are used. In simple mathematical model, we expect that the oldest address has the most connections, but it is not a reality. The average of trillions of addresses everyone has from 2 to 16 links to other addresses. He also explains the concept of "fitness", which encourages people to quickly connect and that explain the success of Facebook.

Robert May from Oxford University was talking about the interactions between networks and their dynamic characteristics applied to IT systems and financial systems. Network can be represented as a food in nature, which connects the predator and prey, and relationships that govern the Internet have similar structures, and certainly similar ratio between prey and predators. Network theory can be applied in medicine and economics.

Jennifer Chayes at Microsoft is a mathematician where "the whole world and people are graph vertices". Network in the online world can be modeled as large graphs, finally, that must be properly sampled in order to be useful. Search engines use the theory of graphs to index the structure of web graph, that the basis for ranking web pages. Her presentation dealt with the "fitness" concept, the models are mutually compete, how to influence the competitive factors. It's also nance exhibited games, which has proven to follow an event does not guarantee a connection, but presence the more increases the likelihood.
She confirmed that the network algorithms big area for commercial development of research with the aim of ranking pages, smart grouping and categorization of data, and eliminating spam and identify new products.

Jon Kleinberg introduced the analysis of large social networks. His statement "Science progresses when the invisible becomes visible", and the Web allows digital visual evidence of social interactions. He presented a fine example of picture with which identified cities, set on Twitter, a site can be obtained by analyzing tags, keywords in messages. For example, he presented a map of Europe where one point is a picture set on Twitter, which is the place. This approach can be used in designing tourist maps.
Mathematical models can be used for the analysis of geographical terms, relationships between people, an analysis of how people react to certain situations and news, as people linked together in groups and so on. Analysis of the data from positive and negative articles about a subject, can be used in the analysis of public opinion (sentiment analysis).
Social networks are present the inner workings of society and knowledge of human anatomy that we have today will be the same knowledge of the society that we get from online social networks.

Pierre Levy, professor of philosophy at the University of Ottawa, called his lecture "The nature of collective intelligence." They began with a lecture presenting the levels of symbolic tools of language, writing, alphabet, the mass media to digital media. He talked about the Newtonian influence on social science.
He said that the mind is not material in nature. It contains ideas, connections between ideas, network, and the idea that the future of science can be represented as a graph applications, ie. as a network of ideas. He defined the "idea" as a concept that has abstract classes and categories, perceptions, images, feelings and emotions.
He said that the idea can be partially present in electronic form. The mind can be defined as a consistent universe of operations of the ideas in a structured semantic space. We can get the electronic-data, images, audio and categorize them, but we can not display the concept of thought. We can show the truth in binary form but not much more than that. We can not see the concept, he has always shown signs (images, audio ..) and the concept is always linked with other concepts, like a gigantic network of concepts. The concept itself is a network.

Manuel Castells is a professor of sociology and its discussion for the social networks on the Internet.
His presentation begins with a statement that it originates from Arpnet 1960th those that experienced a big expansion of the introduction of WWW, the availability of convential communications and more recently access to the Internet via mobile communications. It is expected that by 2014. the number of mobile and fixed users is the same.
He argues that we enter the networked society, but that does not mean end for associations on the basis of common values, interests and projects. Network technologies are a medium for these new forms of social organization, which are global, such as the global network itself.
Media have reported on the negative impact of the Internet has on individuals, such as alienation and exclusion from society, but most research shows that Internet use in strengthening social relationships with family, friends and local community. The internet has a neutral or positive impact in all cultures. Very rarely, it causes the insulation.
Web offers tools for personal independence in creativity, politics and society. This is especially true for women who are at the center of family and social networks. Also, the effects of the circular, the more people use the Internet to a more independent, and the people more independent the more use the Internet.
Most profound social transformation caused by the Internet took place in the last decade, with social networks. Social networks in June 2009. overtaken by the number of email users. It is interesting that when people meet their needs do not stop, but create new ones. Social networks are not just a platform for conversation but for the activities of various kinds, content. There is a clear link between the development of social networks and social life, which is controlled by individuals, not states or corporations. If that were to happen to any social network, then it would go down in history, such as AOL went.
