- Abstract summary: The aim of this study is to provide the most helpful negative reviews under a certain product attribute for online sellers and producers.
It is surprisingly found that positive emotions are more helpful rather than negative emotions in ranking negative reviews.
The presented ranking method could provide e-commerce practitioners with an efficient and effective way to leverage negative reviews from online consumers.

- Abstract: Negative reviews, the poor ratings in postpurchase evaluation, play an
indispensable role in e-commerce, especially in shaping future sales and firm
equities. However, extant studies seldom examine their potential value for
sellers and producers in enhancing capabilities of providing better services
and products. For those who exploited the helpfulness of reviews in the view of
e-commerce keepers, the ranking approaches were developed for customers
instead. To fill this gap, in terms of combining description texts and emotion
polarities, the aim of the ranking method in this study is to provide the most
helpful negative reviews under a certain product attribute for online sellers
and producers. By applying a more reasonable evaluating procedure, experts with
related backgrounds are hired to vote for the ranking approaches. Our ranking
method turns out to be more reliable for ranking negative reviews for sellers
and producers, demonstrating a better performance than the baselines like BM25
with a result of 8% higher. In this paper, we also enrich the previous
understandings of emotions in valuing reviews. Specifically, it is surprisingly
found that positive emotions are more helpful rather than negative emotions in
ranking negative reviews. The unexpected strengthening from positive emotions
in ranking suggests that less polarized reviews on negative experience in fact
offer more rational feedbacks and thus more helpfulness to the sellers and
producers. The presented ranking method could provide e-commerce practitioners
with an efficient and effective way to leverage negative reviews from online
consumers.

In ad-hoc retrieval, evaluation relies heavily on user actions, including implicit feedback.
The role of user feedback in annotators' assessment of turns in a conversational perception has been little studied.
We focus on how the evaluation of task-oriented dialogue systems ( TDSs) is affected by considering user feedback, explicit or implicit, as provided through the follow-up utterance of a turn being evaluated.

Prediction [5.381004207943597]
Existing methods for identifying helpful reviews primarily focus on review text and ignore the two key factors of (1) who post the reviews and (2) when the reviews are posted.
We introduce a dataset and develop a model that integrates the reviewer's expertise, derived from the past review history, and the temporal dynamics of the reviews to automatically assess review helpfulness.

We propose a Sentiment-aware Interactive Fusion Network (SIFN) for review-based item recommendation.

Then, we propose a sentiment prediction task that guides the sentiment learner to extract sentiment-aware features via explicit sentiment labels.

In e-commerce, opinion tags refer to a ranked list of tags provided by the e-commerce platform that reflect characteristics of reviews of an item.
Current mechanisms for generating opinion tags rely on either manual or labelling methods, which is time-consuming and ineffective.
We propose an abstractive opinion tagging framework, named AOT-Net, to generate a ranked list of opinion tags given a large number of reviews.

Using 1, 450, 000 negative reviews from JD.com, the largest B2C platform in China, the behavioral patterns from temporal, perceptional and emotional perspectives are explored.
Consumers from lower levels express more intensive negative feelings, especially on product pricing and seller attitudes.
The value of negative reviews from higher-level consumers is unexpectedly highlighted because of less emotionalization and less biased narration.
