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 .
Relevance feedback is a feature of some information retrieval systems. 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 ...
Rocchio Classification. In machine learning, a nearest centroid classifier or nearest prototype classifier is a classification model that assigns to observations the label of the class of training samples whose mean is closest to the observation.
This is the so called pseudo-relevance feedback (PRF). [6] Pseudo-relevance feedback is efficient in average but can damage results for some queries, [7] especially difficult ones since the top retrieved documents are probably non-relevant. Pseudo-relevant documents are used to find expansion candidate terms that co-occur with many query terms. [8]

A terse, pithy saying, akin to a proverb, maxim, or aphorism. aposiopesis A rhetorical device in which speech is broken off abruptly and the sentence is left unfinished. apostrophe A figure of speech in which a speaker breaks off from addressing the audience (e.g., in a play) and directs speech to a third party such as an opposing litigant or some other individual, sometimes ...
Reader-response criticism argues that literature should be viewed as a performing art in which each reader creates their own, possibly unique, text-related performance. The approach avoids subjectivity or essentialism in descriptions produced through its recognition that reading is determined by textual and also cultural constraints. [ 3 ]
Usually, most of the information conveyed by the utterance has to be inferred. The inference process is based on the decoded meaning, the addressee's knowledge and beliefs, and the context, and is guided by the communicative principle of relevance. [10] For example, take an utterance (5) Susan told me that her kiwis were too sour.
J. R. R. Tolkien's bestselling fantasy novel The Lord of the Rings had an initial mixed literary reception. Despite some enthusiastic early reviews from supporters such as W. H. Auden, Iris Murdoch, and C. S. Lewis, scholars noted a measure of literary hostility to Tolkien, which continued until the start of the 21st century.
