With the assistance of Web 2.0, the bases on client interest, posting on the web surveys has become an undeniably mainstream path for individuals to impart their perspectives to different client’s suppositions and conclusions toward items and administrations. It turns into a typical practice for online business sites to give the offices to individuals to convey and distribute their audits between them. These online audits present an abundance of data on the Services and Products, which will encourage the improvement of their business. Consequently a developing number of late examinations have been centred on the Opinion Mining. For example the Opinion Mining alludes to computational method for assessing the sentiments that are mined from different Web Sources. A couple of Opinion Mining based techniques have been considered and broke down. From our investigation, it is seen that a couple of feeling mining based directed and unaided techniques had not delivered great outcomes because of alluding less number of sentiments inside a similar URL’S and treating the highlights with comparable significance as various. To beat this issue, Topic Anatomy Model TSCAN was proposed, where the Task is called as Topic Anatomy and which sums up and relates the primary pieces of a point with the goal that the per users could comprehend the substance without any problem. By utilizing this model, the more data can be removed and related through their transient closeness, which will give conceivable substance. This model is including imperative part in the Opinion Mining since clients can impart their insights about the items. From our usage, it is seen that this plan gives the best reasonable answer for the client’s advantages and requests. Notwithstanding, it burns-through more opportunity to anticipate the best performing items because of huge informational collections respectively. Consequently our exploration work is proposed and actualized a productive strategy for Opinion Mining called an Efficient Parallel Opinion Mining (EPOM) constructed TSCAN Algorithm separately. It is centring more sites and it is removing more data in equal way, so we can get advanced productive outcome with least execution time. From our outcomes, it is noticed that it gives the best reasonable answer for the client’s advantages and requests and it I s improving the presentation of existing method regarding Quality of Information, Prediction and Execution Time.

Web 2.0 and Knowledge Management (KM) have a considerable overlap. It appears promising to apply Web 2.0 applications for supporting and improving sharing and creation of knowledge. Yet, little research examining the impact of Web 2.0 on KM has been conducted. This chapter presents research examining the suitability and impact of Web 2.0 applications on KM in organizations. Two extensive exploratory case studies were conducted involving 11 interviews with key personnel of two student-run organizations. It is demonstrated how Web 2.0 applications can be used for a number of KM practices mostly related to the areas of asset management and knowledge creation and innovation. Moreover, they suggest that among all the Web 2.0 principles, User-Generated Content and Unbounded Collaboration exert the biggest influence on creating and sharing of knowledge within organizations. The study contributes to the general understanding of how Web 2.0 and KM practices can be interlinked with each other.

<p>The web 2.0 era has shifted brand ownership from communication specialists towards consumers. This is the main idea on which Rodica Sãvulescu builds her argumentation in her recently published book, `<em>Web 2.0 Brands. User-generated content` (2016). </em>The emergence of new technologies blurs the lines between content producers and consumers. In this book, the author addresses the topic of democratization of content in relation with brand communication.</p>

This article reflects on the meaning of the words “control” and “privacy” in light of the intensive diffusion of user generated content on the web. It presents some results of an empirical research based on 145 essays written by Italian students. The data were analysed from a qualitative point of view to understand how young people frame the topic of control on web 2.0. The attention is focused on the metaphors used to describe online platforms and on the social environments they mention when they speak about the impacts of online diffusion of personal content on offline life. The results show that the new control practices cannot be adequately described within the classical framework of vertical control. The traditional panoptic principle of observation has to a certain extent been transformed and the Panopticon itself is no more an effective metaphor to describe the control dynamics on web 2.0.

The main objective of this chapter is to present a general overview of the most relevant applications of text mining and natural language processing technologies evolving and emerging around the Web 2.0 phenomenon (such as automatic categorization, document summarization, question answering, dialogue management, opinion mining, sentiment analysis, outlier identification, misbehavior detection, and social estimation and forecasting) along with the main challenges and new research opportunities that are directly and indirectly derived from them.

Consumer content generation in the Web 2.0 environment from a libertarian perspective is about the democratization of mediated knowledge where it creates the possibilities to produce new knowledge and media economies in a postmodern world. This chapter examines the notions of empowerment afforded by multimedia technologies on the Internet where new forms of knowledge, politics, identity, and community can be fostered through the Web 2.0’s architecture of participation, collaboration, and openness. It also discusses how these unlimited possibilities to produce content present new social and ethical dilemmas. They not only challenge conventional ways in which knowledge and expertise have been constructed in modern and postmodern societies but also require more rigorous methods to identity what can constitute expert knowledge. The production of user-led taxonomies and data repositories has raised the need to re-examine user-generated content and its function and coexistence within the existing systems and archives of knowledge.
