instruction:
In this task, you will be presented with a context from an academic paper and a question separated with a
. You have to answer the question based on the context.
question:
Automation of cQA forums can be divided into three tasks: question-comment relevance (Task A), question-question relevance (Task B), and question-external comment relevance (Task C). In our cQA tasks, the pair of objects are (question, question) or (question, comment), and the relationship is relevant/irrelevant. For task C, in addition to an original question (oriQ) and an external comment (relC), the question which relC commented on is also given (relQ). To incorporate this extra information, we consider a multitask learning framework which jointly learns to predict the relationships of the three pairs (oriQ/relQ, oriQ/relC, relQ/relC).
Question: What supplemental tasks are used for multitask learning?
answer:
Multitask learning is used for the task of predicting relevance of a comment on a different question to a given question, where the supplemental tasks are predicting relevance between the questions, and between the comment and the corresponding question

question:
We collect data by using the Twitter API for saved data, available for public use. For our experiments we collect 3200 tweets filtered by keywords like "fire", "earthquake", "theft", "robbery", "drunk driving", "drunk driving accident" etc.
Question: Do the tweets come from any individual?
answer:
Yes

question:
The training objective is to minimize the negative likelihood of the aligned unanswerable question $ ilde{q}$ given the answerable question $q$ and its corresponding paragraph $p$ that contains the answer $a$ : L=-(q,q,p,a)DP(q|q,p,a;) where $\mathcal {D}$ is the training corpus and $ heta $ denotes all the parameters. Sequence-to-sequence and pair-to-sequence models are trained with the same objective.
Question: What is the training objective of their pair-to-sequence model?
answer:
is to minimize the negative likelihood of the aligned unanswerable question $ ilde{q}$ given the answerable question $q$ and its corresponding paragraph $p$ that contains the answer
