In order to evaluate how well an information retrieval system retrieved topically relevant results, the relevance of retrieved results must be quantified. In Cranfield -style evaluations, this typically involves assigning a relevance level to each retrieved result, a process known as relevance assessment .
a is the number of retrieved, relevant documents, c is the number of non-retrieved, relevant documents (sometimes termed "silence"). Recall is thus an expression of how exhaustive a search for documents is. Precision = a : (a + b), where a is the number of retrieved, relevant documents,
Relevant is something directly related, connected or pertinent to a topic; it may also mean something that is current. Relevant may also refer to: Relevant operator, a concept in physics, see renormalization group
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 ...
Not perfect, but appropriate, adequate, and fulfulling basic requirements? We'd still have to come up with a description of "good enough," however. I have no problem with the word "appropriate." Whatever term we choose, we can define it using ostensive definition i.e. by giving examples, rather than trying to pin down a hard-and-fast definition.
b. the most relevant one compatible with the communicator's abilities and preferences. (Otherwise the communicator would have chosen a more relevant utterance – e.g. one that needs less processing effort and/or achieves more positive cognitive effects on part of the addressee – to convey her meaning.
Relevance, in the common law of evidence, is the tendency of a given item of evidence to prove or disprove one of the legal elements of the case, or to have probative value to make one of the elements of the case likelier or not.
Labelling systems are one of the major components in information architecture, and one of the first steps of an information architecture project is to identify, organize and label relevant chunks of information. [3] When creating labels, the goal is to communicate efficiently, and without taking up too much space.
