What you are looking at is a stylistic tool, that was made to directly demonstrate the amount of emotionally charged or vague words, used in news sources to write about conflict situations.
The notion of the tool is to identify and select manipulatory lexics in news online publications. These kinds of words, word combinations and phrases are put in articles just for one purpose: to create an emotional response from a reader, articulating his opinion and, as a result, his civil position.
The analysis given here is preliminary, imperfect, subjective and incomplete. It can not detect a well-dressed lie, irony or sarcasm. However, it presents a raw picture of how many lexical units might present a problem in a formation of an independent opinion.
The tool also gives a basic image of the writing quality for those who are going to analyze these articles further.
