ibps-so 2016 · Question 132 of 394

The proposal reproduced as Figure 4 sets out ve activities in a xed order. A member of the technology committee has objected that the whole exercise ought to be called data mining, and the analyst has replied that data mining is the name of one step only within the wider process of knowledge discovery in databases, that the three steps before it prepare the data and the step after it judges the result, and that in practice the preparatory steps consume by far the greater part of the e ort. The order of the activities of knowledge discovery in databases, and the place of data mining among them, are correctly stated as:

1. AData mining, selection, pre-processing, transformation, and interpretation — the mining being performed rst upon the raw data and the results then cleaned
2. BSelection, data mining, pre-processing, transformation and interpretation — the mining being performed upon the selected data before it is cleaned
3. CSelection, pre-processing, transformation, data mining, and interpretation and evaluation — data mining being the fourth step, at which the algorithm is applied to the already prepared data to extract the patternsCorrect
4. DPre-processing, selection, interpretation, transformation and data mining — the mining being the last step of all
5. ETransformation, selection, pre-processing, interpretation and data mining — the order being immaterial, since the ve activities may be performed in any sequence Directions (Q133–Q137) : In each of the sentences given below one blank has been left. Five words are suggested beneath the sentence, of which one alone lls the blank in such a way that the sentence is both idiomatic and consistent in sense. Mark the letter of that word as your answer.
