Information retrieval ( IR) in computing and information science is the task of identifying and retrieving information system resources that are relevant to an information need. The information need can be specified in the form of a search query. In the case of document retrieval, queries can be based on full-text or other content-based ...
Knowledge retrieval seeks to return information in a structured form, consistent with human cognitive processes as opposed to simple lists of data items. It draws on a range of fields including epistemology (theory of knowledge), cognitive psychology, cognitive neuroscience, logic and inference, machine learning and knowledge discovery, linguistics, and information technology.
Cue-dependent forgetting, or retrieval failure, is the failure to recall information without memory cues. [1] The term either pertains to semantic cues, state-dependent cues or context-dependent cues. Upon performing a search for files in a computer, its memory is scanned for words. Relevant files containing this word or string of words are ...
Reconstructive memory is a theory of memory recall, in which the act of remembering is influenced by various other cognitive processes including perception, imagination, motivation, semantic memory and beliefs, amongst others. People view their memories as being a coherent and truthful account of episodic memory and believe that their ...
Two-stage theory. The two-stage theory states that the process of recall begins with a search and retrieval process, and then a decision or recognition process where the correct information is chosen from what has been retrieved. In this theory, recognition only involves the latter of these two stages, or processes, and this is thought to ...
Study-phase retrieval theory. A theory that has gained a lot of traction recently [when?] is the study-phase retrieval theory. This theory assumes that the first presentation is retrieved at the time of the second. This leads to an elaboration of the first memory trace.
Retrieval-induced forgetting ( RIF) is a memory phenomenon where remembering causes forgetting of other information in memory. The phenomenon was first demonstrated in 1994, although the concept of RIF has been previously discussed in the context of retrieval inhibition . RIF is demonstrated through a three-phase experiment consisting of study ...
Memory and retention are linked because any retained information is kept in human memory stores, therefore without human memory processes, retention of material would not be possible. [4] In addition, memory and the process of learning are also closely connected. Memory is a site of storage and enables the retrieval and encoding of information ...
