  Precision Marketing helps break down the perspe Marketers around the globe are recognizing that increasing customization and precision is critical to their commercial success. Rather than devoting marketing budgets to mass campaigns, precision marketers are mining customer data for predispositions to spend so that they can target buyers in /5. The workshop participants discussed a variety of topics including an overview of precision medicine and its potential, the relevance of health literacy to the success of precision medicine efforts, and perspectives and understanding of different groups, such as . What is Precision/Relevance? Definition of Precision/Relevance: Precision is an information retrieval performance measure that quantifies the fraction of retrieved documents which are known to be relevant. for exaggerating his importance in events (Jenkins, ).6 ‘InspectorThompson in his two volumes of reminiscences is good at capturing the heart of the matter but less reliable on exact dates, times and places than might have been hoped for a meticulous detective’. (Jenkins, ).

Precision goes one step further than Accuracy. It demands that the words and data used are exact. If no more details could be added, then it has Precision. Relevance means that everything included is important, that each part makes a difference. If something is focused on what needs to be said, there is Relevance. Depth makes the argument. The precision of a measurement system, related to reproducibility and repeatability, is the degree to which repeated measurements under unchanged conditions show the same results. [2] [3] Although the two words precision and accuracy can be synonymous in colloquial use, they are deliberately contrasted in the context of the scientific method.   Accuracy and precision are two important factors to consider when taking data accuracy and precision reflect how close a measurement is to an actual value, but accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value.   Suppose that you buy kg of potatoes in a grocery store as measured with a scale with precision kg. Then you drop off kg of potatoes at your laboratory as measured by a scale with precision kg. Finally, you go home and add kg of potatoes as measured by a bathroom scale with precision kg.

I’m so glad that I can answer a question in my study area as my first answer. In the beginning, I have to say, English is not my native language, so maybe there are some grammar or spelling mistakes in the answers. Please understand it and let me. In information retrieval contexts, precision and recall are defined in terms of a set of retrieved documents (e.g. the list of documents produced by a web search engine for a query) and a set of relevant documents (e.g. the list of all documents on the internet that are relevant for a certain topic), cf. relevance.   proximated by the use of document relevance (Section ). The key utility measure is user happiness. Speed of response and the size of the index are factors in user happiness. It seems reasonable to assume that relevance of results is the most important factor: blindingly fast, useless answers do not make a user happy. Differentiating between precision and relevancy. Relevant costs. Relevant costs are those types of costs that can change during a certain course of time in respect to a particular decision. For decision making it is important that relevancy of cost must be clear.
