- Abstract summary: Community Question Answering (CQA) sites have spread and multiplied significantly in recent years.
One practical way of finding such answers is automatically predicting the best candidate given existing answers and comments.
We address this limitation using a novel method for predicting the best answers using the questioner's background information and other features.

- Abstract: Community Question Answering (CQA) sites have spread and multiplied
significantly in recent years. Sites like Reddit, Quora, and Stack Exchange are
becoming popular amongst people interested in finding answers to diverse
questions. One practical way of finding such answers is automatically
predicting the best candidate given existing answers and comments. Many studies
were conducted on answer prediction in CQA but with limited focus on using the
background information of the questionnaires. We address this limitation using
a novel method for predicting the best answers using the questioner's
background information and other features, such as the textual content or the
relationships with other participants. Our answer classification model was
trained using the Stack Exchange dataset and validated using the Area Under the
Curve (AUC) metric. The experimental results show that the proposed method
complements previous methods by pointing out the importance of the
relationships between users, particularly throughout the level of involvement
in different communities on Stack Exchange. Furthermore, we point out that
there is little overlap between user-relation information and the information
represented by the shallow text features and the meta-features, such as time
differences.

Question and answer (Q&A) platforms usually recommend question-answer pairs to meet users' knowledge acquisition needs.
This makes user behaviors more complex, and presents two challenges for Q&A recommendation.
We introduce Question & Answer Graph Collaborative Filtering (QAGCF), a graph neural network model that creates separate graphs for collaborative and semantic views.

Task [2.5091819952713057]
Community question answering (CQA) forums are Internet-based platforms where users ask questions about a topic and other expert users try to provide solutions.
Many CQA forums such as Quora, Stackoverflow, Yahoo!Answer, StackExchange exist with a lot of user-generated data.
These data are leveraged in automated CQA ranking systems where similar questions (and answers) are presented in response to the query of the user.

We introduce CREPE, a QA dataset containing a natural distribution of presupposition failures from online information-seeking forums.
We find that 25% of questions contain false presuppositions, and provide annotations for these presuppositions and their corrections.
We show that adaptations of existing open-domain QA models can find presuppositions moderately well, but struggle when predicting whether a presupposition is factually correct.

We propose a framework with Multifaceted Improvements for Conversational open-domain Question Answering (MICQA)
Firstly, the proposed KL-divergence based regularization is able to lead to a better question understanding for retrieval and answer reading.
Second, the added post-ranker module can push more relevant passages to the top placements and be selected for reader with a two-aspect constrains.
Third, the well designed curriculum learning strategy effectively narrows the gap between the golden passage settings of training and inference, and encourages the reader to find true answer without the golden passage assistance.
