Community-based Question Answering (CQA), which allows users to acquire their desired information, has increasingly become an essential component of online services in various domains such as E-commerce, travel, and dining.However, an overwhelming number of CQA pairs makes it difficult for users without particular intent to find useful information spread over CQA pairs.To help users quickly digest the key information, we propose the novel CQA summarization task that aims to create a concise summary from CQA pairs.To this end, we first design a multi-stage data annotation process and create a benchmark dataset, CO-QASUM, based on the Amazon QA corpus.We then compare a collection of extractive and abstractive summarization methods and establish a strong baseline approach DedupLED for the CQA summarization task.Our experiment further confirms two key challenges, sentencetype transfer and deduplication removal, towards the CQA summarization task.Our data and code are publicly available.1 * Work done while at Megagon Labs. 1 https://github.com/megagonlabs/ qa-summarization Q: Is this actually a rigid board or more of a floppy mat?A: It is rigid.themain board is rigid,the two sides are semi.Q: Is this actually a rigid board or more of a floppy mat?A: The main area is very sturdy.Then there are two work area pads that are more flexible so when moving those I keep two hands on them.Q: how wide is each Side piece?"A: 16 inches wide (there are two).Q: will this mat hold 1000 piece puzzle?A: most certainly will.… … (omitted 27 QAs) Summary: This puzzle board comes with a rigid main board.You can arrange pieces in the middle and on two side pieces, and then pick up those side pieces to place them atop the middle area before folding the wings in.The dimension of the puzzle space is 32"x21.75".The closed unit is almost the same size as the puzzle workspace (32"x21.75").There are two 16" wide side inserts.The mat holds most 1000 pieces puzzles.It is too big to use on you lap and definitely needs a table.(a).QAs for a puzzle board product (Input) (b).Summary of QAs (Output) Q: what is the storage size when case is fully closed for storage?A: Closed size is 32.25 x 22.75".Q: What size is the closed unit?A: Closed is almost the same size as the puzzle workspace.32.25 x 22.
