// The advantage of this approach is that the link between the news wave and a key event is unambiguous since it is (mostly) pre-defined by case selection. This disadvantage is that the number of cases that can be surveyed is limited and that cases are selected on an ad-hoc or strategic logic that may induce biases and blind spots.

// Finding news waves and linking them to key events can be extremely useful for Communication Researchers, particularly those interested in identifying turning points in debates, focusing periods of discourse, and building of collective memory and collective identity. // Before introducing our own procedure for extracting, labelling, and validating news waves, we will investigate which procedures have been used in the past, what they achieve, what their limitations are, and which common problems and challenges need to be tackled by any procedure detecting and labelling news waves.

// We delve into both concepts and their relationship to later be able to validate the results of news wave detection and labelling as to whether they capture actual news waves and these actual news waves are linked to key events. It also helps understand the social and scientific significance of a procedure that automatically detects and labels such news waves.
