Definition: In this task, you will be presented with a context from an academic paper and a question based on the context. You have to classify the questions into "Extractive", "Abstractive", or "Yes-no" questions. Extractive questions can be answered by concatenating extracts taken from a context into a summary while answering abstractive questions involves paraphrasing the context using novel sentences. Yes-no question is a question whose expected answer is one of two choices, one that affirms the question and one that denies the question. Typically, the choices are either yes or no.

Positive Example 1 -
Input: We build a dataset of Twitter accounts based on two lists annotated in previous works. For the non-factual accounts, we rely on a list of 180 Twitter accounts from BIBREF1. On the other hand, for the factual accounts, we use a list with another 32 Twitter accounts from BIBREF19 that are considered trustworthy by independent third parties. 
 Question: How did they obtain the dataset?
Output: Extractive

Positive Example 2 -
Input: We evaluate our pointer-generator performance using BLEU score. The baseline language model is trained using RNNLM BIBREF23 . Perplexity measure is used in the evaluation.

 
 Question: Did they use other evaluation metrics?
Output: Yes-no

Negative Example 1 -
Input: For the English version, we performed both a thorough manual analysis and automatic evaluation across three commonly used TS datasets from two different domains  For the English version, we performed both a thorough manual analysis and automatic evaluation across three commonly used TS datasets from two different domains  The evaluation of the German version is in progress. 
 Question: What are the corpora used for the task?
Output: Yes-no

Negative Example 2 -
Input: For Turkish, as the first dataset, we utilised the movie reviews which are collected from a popular website. The number of reviews in this movie corpus is 20,244 and the average number of words in reviews is 39. Each of these reviews has a star-rating score which is indicative of sentiment. These polarity scores are between the values 0.5 and 5, at intervals of 0.5. We consider a review to be negative it the score is equal to or lower than 2.5. On the other hand, if it is equal to or higher than 4, it is assumed to be positive. We have randomly selected 7,020 negative and 7,020 positive reviews and processed only them. 
 Question: What details are given about the movie domain dataset?
Output: Extractive

Now complete the following example -
Input: We refer the reader to BIBREF10 for more details on the propaganda techniques; below we report the list of techniques:

Propaganda Techniques ::: 1. Loaded language.
Using words/phrases with strong emotional implications (positive or negative) to influence an audience BIBREF11.

Propaganda Techniques ::: 2. Name calling or labeling.
Labeling the object of the propaganda as something the target audience fears, hates, finds undesirable or otherwise loves or praises BIBREF12.

Propaganda Techniques ::: 3. Repetition.
Repeating the same message over and over again, so that the audience will eventually accept it BIBREF13, BIBREF12.

Propaganda Techniques ::: 4. Exaggeration or minimization.
Either representing something in an excessive manner: making things larger, better, worse, or making something seem less important or smaller than it actually is BIBREF14, e.g., saying that an insult was just a joke.

Propaganda Techniques ::: 5. Doubt.
Questioning the credibility of someone or something.

Propaganda Techniques ::: 6. Appeal to fear/prejudice.
Seeking to build support for an idea by instilling anxiety and/or panic in the population towards an alternative, possibly based on preconceived judgments.

Propaganda Techniques ::: 7. Flag-waving.
Playing on strong national feeling (or with respect to a group, e.g., race, gender, political preference) to justify or promote an action or idea BIBREF15.

Propaganda Techniques ::: 8. Causal oversimplification.
Assuming one cause when there are multiple causes behind an issue. We include scapegoating as well: the transfer of the blame to one person or group of people without investigating the complexities of an issue.

Propaganda Techniques ::: 9. Slogans.
A brief and striking phrase that may include labeling and stereotyping. Slogans tend to act as emotional appeals BIBREF16.

Propaganda Techniques ::: 10. Appeal to authority.
Stating that a claim is true simply because a valid authority/expert on the issue supports it, without any other supporting evidence BIBREF17. We include the special case where the reference is not an authority/expert, although it is referred to as testimonial in the literature BIBREF14.

Propaganda Techniques ::: 11. Black-and-white fallacy, dictatorship.
Presenting two alternative options as the only possibilities, when in fact more possibilities exist BIBREF13. As an extreme case, telling the audience exactly what actions to take, eliminating any other possible choice (dictatorship).

Propaganda Techniques ::: 12. Thought-terminating cliché.
Words or phrases that discourage critical thought and meaningful discussion about a given topic. They are typically short and generic sentences that offer seemingly simple answers to complex questions or that distract attention away from other lines of thought BIBREF18.

Propaganda Techniques ::: 13. Whataboutism.
Discredit an opponent's position by charging them with hypocrisy without directly disproving their argument BIBREF19.

Propaganda Techniques ::: 14. Reductio ad Hitlerum.
Persuading an audience to disapprove an action or idea by suggesting that the idea is popular with groups hated in contempt by the target audience. It can refer to any person or concept with a negative connotation BIBREF20.

Propaganda Techniques ::: 15. Red herring.
Introducing irrelevant material to the issue being discussed, so that everyone's attention is diverted away from the points made BIBREF11. Those subjected to a red herring argument are led away from the issue that had been the focus of the discussion and urged to follow an observation or claim that may be associated with the original claim, but is not highly relevant to the issue in dispute BIBREF20.

Propaganda Techniques ::: 16. Bandwagon.
Attempting to persuade the target audience to join in and take the course of action because “everyone else is taking the same action” BIBREF15.

Propaganda Techniques ::: 17. Obfuscation, intentional vagueness, confusion.
Using deliberately unclear words, to let the audience have its own interpretation BIBREF21, BIBREF11. For instance, when an unclear phrase with multiple possible meanings is used within the argument and, therefore, it does not really support the conclusion.

Propaganda Techniques ::: 18. Straw man.
When an opponent's proposition is substituted with a similar one which is then refuted in place of the original BIBREF22. 
 Question: What are the 18 propaganda techniques?
