The idea behind relevance feedback is to take the results that are initially returned from a given query, to gather user feedback, and to use information about whether or not those results are relevant to perform a new query. We can usefully distinguish between three types ...
Relevance level "Medium" – Information that is "once removed" is less directly relevant, should receive a higher level of scrutiny and achieve higher levels in other areas (such as neutrality, weight and strength [further explanation needed] and objectivity of the material and sourcing) before inclusion, but may still may be sufficiently ...
The formal study of relevance began in the 20th century with the study of what would later be called bibliometrics. In the 1930s and 1940s, S. C. Bradford used the term "relevant" to characterize articles relevant to a subject (cf., Bradford's law). In the 1950s, the first information retrieval systems emerged, and researchers noted the ...
The feedback form starts with a simple questions, then offers a comment box. The feedback form is a blue box at the bottom of Wikipedia articles, with a simple question: "Did you find what you were looking for?” and a comments box (see example above). For now, it is only available on a small test sample on the English Wikipedia.
The Rocchio algorithm is based on a method of relevance feedback found in information retrieval systems which stemmed from the SMART Information Retrieval System developed between 1960 and 1964. Like many other retrieval systems, the Rocchio algorithm was developed using the vector space model .
This “feedback form” asks if you found what you were looking for. Click on ‘Yes’ or ‘No’ to let the editors if you found the article useful or not. Then add a comment about the article. For example, you can include suggestions for improvement, ask a question, give praise to the authors or report a problem.
