2.3 Origins of data quality issues: Garbage In Garbage Out

"On two occasions I have been asked,—"Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" … I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question. “

- Charles Babbage

As we previously saw data quality issues with search engines are not coming from technology. They are in fact coming from:

– The one who wrote the contents of the results, it can be misspellings, no concrete sources to justify himself, no adoption of standards, advertisement;

– The one who type in the request (cf. chapter 3.3.6.1: Search engine use awareness);

The next parts will develop this first point in detail.
