SentiHood: Targeted Aspect Based Sentiment Analysis Dataset for Urban Neighbourhoods
This work addresses the need for more nuanced sentiment analysis in urban planning or social media monitoring, though it is incremental by extending existing tasks with a new dataset.
The authors tackled the problem of extracting fine-grained sentiment towards specific aspects of multiple entities in user comments by introducing the targeted aspect-based sentiment analysis task and the SentiHood dataset from a QA platform, developing baselines with logistic regression and recurrent neural networks.
In this paper, we introduce the task of targeted aspect-based sentiment analysis. The goal is to extract fine-grained information with respect to entities mentioned in user comments. This work extends both aspect-based sentiment analysis that assumes a single entity per document and targeted sentiment analysis that assumes a single sentiment towards a target entity. In particular, we identify the sentiment towards each aspect of one or more entities. As a testbed for this task, we introduce the SentiHood dataset, extracted from a question answering (QA) platform where urban neighbourhoods are discussed by users. In this context units of text often mention several aspects of one or more neighbourhoods. This is the first time that a generic social media platform in this case a QA platform, is used for fine-grained opinion mining. Text coming from QA platforms is far less constrained compared to text from review specific platforms which current datasets are based on. We develop several strong baselines, relying on logistic regression and state-of-the-art recurrent neural networks.
