Source criticism (or information evaluation) is the process of evaluating an information source, i.e.: a document, a person, a speech, a fingerprint, a photo, an observation, or anything used in order to obtain knowledge. In relation to a given purpose, a given information source may be more or less valid, reliable or relevant.

Among genealogists, a primary source comes from a direct witness, a secondary source comes from second-hand information or hearsay told to others by witnesses, and tertiary sources can represent either a further link in the chain or an analysis, summary, or distillation of primary and/or secondary sources. In this system, an elderly woman's ...
In science and engineering, root cause analysis (RCA) is a method of problem solving used for identifying the root causes of faults or problems. [1] It is widely used in IT operations, manufacturing, telecommunications, industrial process control, accident analysis (e.g., in aviation, [2] rail transport, or nuclear plants), medical diagnosis, the healthcare industry (e.g., for epidemiology ...
Sources of information are commonly categorized as primary, secondary, or tertiary sources.In brief, a primary source is one close to the event with firsthand knowledge (for example, an eyewitness); a secondary source is at least one step removed (for example, a book about an event written by someone not involved in it); and a tertiary source is an encyclopaedia or textbook that provides a ...
Uncertainty in meaning of terms presents problems when attempting to search and cross reference data from multiple sources. [18] The primary method for resolving data analysis issues is reliance on domain knowledge from an expert. This is a very time-consuming and costly method of conducting link analysis and has inherent problems of its own.
The CRAAP test is a test that evaluates the objective reliability of information sources across academic disciplines. CRAAP is an acronym for Currency, Relevance, Authority, Accuracy, and Purpose. [1] Because a vast number of sources exist online, it can be difficult to tell if sources are trustworthy enough to use for research.
In one approach, exemplified by principal and independent component analysis, one seeks source signals that are minimally correlated or maximally independent in a probabilistic or information-theoretic sense. A second approach, exemplified by nonnegative matrix factorization, is to impose structural constraints on the source signals. These ...
