Information retrieval and Information extraction in Web 2.0 environment

With the rise of Web 2.0 paradigm new trends in information retrieval (IR) and information extraction (IE) can be observed. Significance of IR/IE as fundamental method of acquiring new and up-to-date information is crucial for efficient decision making. Social aspects of modern information retrieval are gaining on its importance over technical aspects. The main reason for this trend is that IR and IE services are becoming more and more widely available to end users that are not information professionals but regular users. Also new methods that rely primarily on user interaction and communication show similar success in IR and IE tasks. Web 2.0 has overall positive impact on IR and IE as it is based on a more structured data platform than the earlier web. Moreover, new tools are being developed for online IE services that make IE more accessible even to users without technical knowledge and background. The goal of this paper is to review these trends and put them into context of what improvements and potential IR and IE have to offer to knowledge engineers, information workers, but also typical Internet users.
