With the rise of Web 2.0 paradigm new trends in Information Retrieval (IR) and Information Extraction (IE) can be observed. Significance of IR and 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.
