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 ...
Some theorists, like Paul Cobley and Peter J. Schulz, distinguish models of communication from theories of communication. This is based on the idea that theories of communication try to provide a more abstract conceptual framework that is strong enough to accurately represent the underlying reality despite its complexity.

Relevance theory is a framework for understanding the interpretation of utterances. It was first proposed by Dan Sperber and Deirdre Wilson , and is used within cognitive linguistics and pragmatics .
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 .
[1] [23] [12] Feedback means that the receiver responds by sending their own message back to the original sender. This makes the process more complicated since each participant acts both as sender and receiver. For many forms of communication, feedback is of vital importance, for example, to assess the effect of the communication on the audience.
An example is the relation between sender and receiver: it influences the goal of communication and the roles played by the participants. Schramm's criticism of linear models of communication, which lack a feedback loop, has been very influential.
On e-commerce platforms like Etsy, TikTok Shop, eBay and Redbubble, sellers are hawking merchandise featuring designs inspired by the fatal shooting of UnitedHealthcare CEO Brian Thompson.
Theory can be seen as a way to map the world and make it navigable; communication theory gives us tools to answer empirical, conceptual, or practical communication questions. [1] Communication is defined in both commonsense and specialized ways. Communication theory emphasizes its symbolic and social process aspects as seen from two ...
