Three Critical Questions

Monday

1. How are the traditional interactions different from social interactions in terms of building relations etc? How far is this social media effective on the peoples real life? How will this effect the user’s self perception?

2. How far the applications developed at the micro level (basic software applications) can be successful at the macro level, because the later part requires more analysis, requires resolving issues and also requires change in the design. Apart from the above specified issues there is one more problem associated with this i.e. “familiarization”.

3. Authors say that we need some analytical methods to understand the web behavior at the macro level. What actually are these analytic methods? What are the desirable analytical methods?

1. The author says that the content of the web page should be changed according to the user. If that method is followed, how the search engines can find ontological the relationship between two applications?
2. According to the author, the semantic web systems should follow the software design metrics in order to understand the application. But, is it possible to apply current software metrics to the semantic applications?
3. According to the author, new analytic metrics should be invented in order to understand current semantic web. What are the new analytic metrics?

1. In micro scale, Web is a combination of artificial intelligence and rules where as while coming towards the macro scale it is reciprocal action or the influence of the human beings creating and linking as well as consuming information. But how best the technology will be when combining these micro and macro scales at a point?
2. The author suggests that the rising properties generate surprising properties which requires new analytical methods to be clarified. What are the analytical methods to be understood and how well they can be understood by the developed considering time constraints and complexity towards a project?
3. Author explains the concept of the properties not being used in explaining the performance of the web-sites over the time by giving a Wikipedia example. What are constraints and factors considered in the analysis?
4. Web graph is considered as the impractical idea of the web based on only one part of the processing and the protocols under the function. How does the Web graph play a key role in describing the Web as it just provides the abstraction of the Web?

1. The paper stated that the size of the web grows faster and faster. When data is shared in the web, how the factors like “reliability”, “trustworthy”, “security” is achieved?
2. The paper stated about the web architecture, principles, protocols etc. But how these are used to achieve information sharing is not stated in the paper.
3. Can a “web-graph” explain the solutions for “power loss” and “growth models” when there are thousands of links interconnected in a web-site?

• The author says that the levels of social interaction as enabled by the web are hampered to study by the disciplinary boundaries arising from the underlying networking applications and the study of the actual social applications. How does this anomaly be fixed and what significance does the author present to the context of Web study in this case?
• While criticizing the web graph model for study of web performance, author says that the information on the web is not actually available for wide scale analysis and this can be possible when there is cross reference mechanism available between different sites by allowing proper access to other sites. What kind of potential trade-off is this confidentiality vs. the evolving of the study of Web Technology?
• In the concluding notes, author mentions the need for development of Web technology in such a way where there is scope for finding new ways to anticipate behavior of humans and to integrate the development of Web to find and explore micros to enable macros with more scope. But the author does not still provide any reference as to how be the design of such a micro. What could be such a model where there is inferencing mechanism to develop suitable micros for better macros and hence a potential semantic web?

Group 6:

1) Why web has remained as an entity even though it has a huge success in technology as well as in computing?
2) Authors tell that only courses related to web applications are taught in any schools or in any departments but they are not covering the concepts related to architecture, protocols and principles of web. Why it is this way?
3) Even though the emerging technology-semantic web is considered as a most important technology on the web, it has some effects. What are those effects?

1.“ How can we modify the web’s underlying architecture to make it support the human interaction? There are many problems in the semantic web which supports the human interaction. One of those problems is the creation of ontologies which are used by the semantic web technologies. So how can we design an ontology which is suitable for only one particular domain?”
2.“ The XML based languages like OWL and RDF are complex and complicated to learn and to analyze even by the technical people. How can we accommodate these for distributed nature of semantic web?”
3.“ Inorder to design the web, it is suggested to build it at the micro-level and test it for small group of people and later extend it for macro-level. But the problem is that how is the analysis made to know whether it supports right functionalities of macro scale effects? How do we know the side effects at the macro level?”
4.“ The author described the web interms of graph and analysed the growth of the graph using algorithms like HITS, PageRank. How do we analyse the properties of the graph using these algorithms? What are the models that are best suited to capture the evolution of the graph?”

1) When the micro is designed and build how can we know that the micro which was built has the correct “functionalities” for the macro which will be resulted and how can we assess the “macro scale effects”
2) In Google there will be links say upto “twenty million” that represents “new” “URI’s” which encodes terms given for the search. The “web graph” doesn’t answer the questions which arise like will the links pursue “ “same power laws”” explains the actions.
3) How the issues like what kind of algorithms must be used and how can we make “social policy expectations” and the issues regarding the cultural differences which has an effect on the “development and use” of the new generation of the “interacting social machine” can be answered.

How does the author explain that the social machine will someday be significantly more effective than those we have today? Just because the amount of use of web will be increasing does the author say that it will be more effect today, is this reason alone enough to say that, may be the semantic web could lead to misleading factors which may in result affect the social machine.

Is the Web graph reliable enough to explain the features of the web, let’s suppose it constantly updates the various dynamic links and web pages will it be sufficient to explain the complexity behind the designing of the web?

Why does the author feel that the consequences are difficult to interpret,we know the importance of the web ,we know its appliucations why is that the author still not able to predict the social consequences ,if at all he has further any doubts why does he conclude that the web needs to be socialized ,is it really worth taking that risk?

1) The author says that there is a heavy usage of tagging to retrieve data. The tagging may not be always correct for the correct data. How can the validation of the data be proved by tagging?
2) How efficient are the HITS and PageRank algorithms to validate the growth of the web graph?
3) The author tries to convey the web as a dynamic and changing entity. How well the concepts of semantic web are pertaining to web science?

Group 3:

Member Name: Chi Zhang

1. About the current web graph. Although the current web graph has many defects, it can still show many features and information about the web. We can perfect it by introducing new symbols and functions, and perhaps introducing new types of diagrams to show different contents, why does the author state that we need a brand new modeling instead of doing some add-on to current ones? The web graph is able to show resources passing from one node to another by request, so why he wants to attack that? The web graph is extendable, the author should not just look at the basic form of it and ignore another side of the graph.

2. The author states that the web may play a major role in communication in the future. Certain rules and policies will be put forward. However, how does he know people will view the web in this way? The web may just be used as a tool for communication since not everything can be conveyed by web communication.

3. When the author is talking about the semantic web, he stresses more on domain knowledge and data. In fact, the concepts and classes are also very important part of the knowledge base. Why does he ignore so many things?

Group 4:

Member Name:Karunapiya Rameshwaram, Shaiv, Anusha Vunnam

Critical Questions:
1.)Can all the disparities on communication at all the levels be represented on a graph?
2.)The article elucidates that in order to identify and extend the better successions of web, it should be devised and fabricated on micro hoping, but how can its performance be made certain?
3.)Does the products developed by the corporations are adaptable to the further enhancements in the World Wide Web. If so then to how far extent can they support the changes in the future?

1. According to paper at micro level web is a set of protocols and artificial languages whereas at macro level it is basically an interaction between humans and the system. So how do we categorize this and merge them into an application which is useful at a large scale level?
2. Author says that any site success depends on how well it is useful and attractive to the users who are going to use them. But with such vast population as users with different requirements which factors should be considered to analyze it?
3. Semantic web which is an emerging technology which allows both developers and users to interact with the real time objects is been described. But though with such good application why is that it is not gaining enough popularity and why such little work is being taken up?

1) Author stated that “The best way to understand a web is as a set of protocols.” Inversely can by having good understanding on protocol can we develop Good Web application ?
2) “Cookies representing previous state may be used, causing different users to see different content based on earlier behavior and visits.” By having the access to cookies can there be a security threat (It becomes easy for others to hack)?
3) Author states that “Formal models of privacy has demonstrated that traditional cryptographic approaches to privacy protection can fail in open web environments.” Then how can the problem be solved ?

Group 9:

Member Name: Satish Bhat, Holly Vo

1. Should web infrastructure, algorithms, and protocols be taught in web design course? Does a web designer needs that much and deep knowledge to use exposed web services and APIs?
2. Should web testing phase be more involved with automation to simulate the macro-scale test scenario before release (rather than build and test in micro-scale scenario and release to a macro-scale).
3. How to encrypt private data in open web environment? Also how to filter data to satisfy government rules of each country?

1) The more detailed explanation and specific steps for web development should be suggested to support their opinion. It is too abstract when comparing with software application development.
2) The approach for the Web Science has too bulky scale. It includes social interactions, web technology, and all the requirements for connecting structures. They indicated the Web Science has complexity because of those matters. However, to make users understand and get popularity the problems should be more simple and easier. There should be the suggestion for this.
3) They described that the graph cannot deal with all matters of the web, but they didn’t suggest other ways for evaluating the web. Specifically, they didn’t deal with the issue about analysis the dynamics such as choosing the identical link several times. However, we can not get the solutions for this.
4) The challenging issues for researchers are fairly attractive. The questions cover many directions such as theoretic, design, and integration of the infrastructure.
5) They have the only optimistic view for the Semantic Web. They didn’t have attentions about obstacles of Semantic Web development.
