Types of Aspect Terms in Aspect-Oriented Sentiment Labeling
نویسندگان
چکیده
The paper studies the diversity of ways to express entity aspects in users’ reviews. Besides explicit aspect terms, it is possible to distinguish implicit aspect terms and sentiment facts. These subtypes of aspect terms were annotated during SentiRuEval evaluation of Russian sentiment analysis systems organized in 2014–2015. The created annotation gives the possibility to analyze the contribution of non-explicit aspects to the overall sentiment of a review, their main patterns, and possible use.

متن کاملAspect-Based Relational Sentiment Analysis Using a Stacked Neural Network Architecture
Sentiment analysis can be regarded as a relation extraction problem in which the sentiment of some opinion holder towards a certain aspect of a product, theme or event needs to be extracted. We present a novel neural architecture for sentiment analysis as a relation extraction problem that addresses this problem by dividing it into three subtasks: i) identification of aspect and opinion terms, ...
متن کاملA Bayesian Model for Joint Unsupervised Induction of Sentiment, Aspect and Discourse Representations
We propose a joint model for unsupervised induction of sentiment, aspect and discourse information and show that by incorporating a notion of latent discourse relations in the model, we improve the prediction accuracy for aspect and sentiment polarity on the sub-sentential level. We deviate from the traditional view of discourse, as we induce types of discourse relations and associated discours...

In this paper, we present a structural learning model for joint sentiment classification and aspect analysis of text at various levels of granularity. Our model aims to identify highly informative sentences that are aspect-specific in online custom reviews. The primary advantages of our model are two-fold: first, it performs document-level and sentence-level sentiment polarity classification jo...
