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.

[Q]: The embeddings for words and POS tags were pre-trained on a large unannotated corpus consisting of the first 1 billion characters from Wikipedia. 
 Question: Do they use pretrained models as part of their parser?
[A]: Yes-no


[Q]:  We then train a paragraph vector model using the Document to Vector (Doc2Vec) framework BIBREF7 on the whole set (13 million) of preprocessed text records, although training on smaller sets (1 million) also produces good results. 
 Question: Which text embedding methodologies are used?
[A]: Extractive


[Q]: Next, we analyzed all tweets labeled as offensive to better understand how Arabic speakers use offensive language. Here is a breakdown of usage:

Direct name calling: The most frequent attack is to call a person an animal name, and the most used animals were كلب> (“klb” - “dog”), حمار> (“HmAr” - “donkey”), and بهيم> (“bhym” - “beast”). The second most common was insulting mental abilities using words such as غبي> (“gby” - “stupid”) and عبيط> (“EbyT” -“idiot”). Some culture-specific differences should be considered. Not all animal names are used as insults. For example, animals such as أسد> (“Asd” - “lion”), صقر> (“Sqr” - “falcon”), and غزال> (“gzAl” - “gazelle”) are typically used for praise. For other insults, people use: some bird names such as دجاجة> (“djAjp” - “chicken”), بومة> (“bwmp” - “owl”), and غراب> (“grAb” - “crow”); insects such as ذبابة> (“*bAbp” - “fly”), صرصور> (“SrSwr” - “cockroach”), and حشرة> (“H$rp” - “insect”); microorganisms such as جرثومة> (“jrvwmp” - “microbe”) and طحالب> (“THAlb” - “algae”); inanimate objects such as جزمة> (“jzmp” - “shoes”) and سطل> (“sTl” - “bucket”) among other usages.

Simile and metaphor: Users use simile and metaphor were they would compare a person to: an animal as in زي الثور> (“zy Alvwr” - “like a bull”), سمعني نهيقك> (“smEny nhyqk” - “let me hear your braying”), and هز ديلك> (“hz dylk” - “wag your tail”); a person with mental or physical disability such as منغولي> (“mngwly” - “Mongolian (down-syndrome)”), معوق> (“mEwq” - “disabled”), and قزم> (“qzm” - “dwarf”); and to the opposite gender such as جيش نوال> (“jy$ nwAl” - “Nawal's army (Nawal is female name)”) and نادي زيزي> (“nAdy zyzy” - “Zizi's club (Zizi is a female pet name)”).

Indirect speech: This type of offensive language includes: sarcasm such as أذكى إخواتك> (“A*kY AxwAtk” - “smartest one of your siblings”) and فيلسوف الحمير> (“fylswf AlHmyr” - “the donkeys' philosopher”); questions such as ايه كل الغباء ده> (“Ayh kl AlgbA dh” - “what is all this stupidity”); and indirect speech such as النقاش مع البهايم غير مثمر> (“AlnqA$ mE AlbhAym gyr mvmr” - “no use talking to cattle”).

Wishing Evil: This entails wishing death or major harm to befall someone such as ربنا ياخدك> (“rbnA yAxdk” - “May God take (kill) you”), الله يلعنك> (“Allh ylEnk” - “may Allah/God curse you”), and روح في داهية> (“rwH fy dAhyp” - equivalent to “go to hell”).

Name alteration: One common way to insult others is to change a letter or two in their names to produce new offensive words that rhyme with the original names. Some examples of such include changing الجزيرة> (“Aljzyrp” - “Aljazeera (channel)”) to الخنزيرة> (“Alxnzyrp” - “the pig”) and خلفان> (“xlfAn” - “Khalfan (person name)”) to خرفان> (“xrfAn” - “crazed”).

Societal stratification: Some insults are associated with: certain jobs such as بواب> (“bwAb” - “doorman”) or خادم> (“xAdm” - “servant”); and specific societal components such بدوي> (“bdwy” - “bedouin”) and فلاح> (“flAH” - “farmer”).

Immoral behavior: These insults are associated with negative moral traits or behaviors such as حقير> (“Hqyr” - “vile”), خاين> (“xAyn” - “traitor”), and منافق> (“mnAfq” - “hypocrite”).

Sexually related: They include expressions such as خول> (“xwl” - “gay”), وسخة> (“wsxp” - “prostitute”), and عرص> (“ErS” - “pimp”).
