Online reviews are valuable resources not only for consumers to make decisions before purchase, but also for providers to get feedbacks for their services or commodities. In Aspect Based Sentiment Analysis (ABSA), it is critical to identify aspect categories and extract aspect terms from the sentences of user-generated reviews. However, the two tasks are often treated independently, even though...

Two extensions are formulated of the analysis of the allocation of decision rights in Hendrikse and Veerman (2001). First, the incomplete contracts in their article can be viewed as simple long-term contracts, i.e. it is not allowed to make the allocation of authority contingent on the circumstances. Contingent long-term contracts are now considered. Second, another aspect of decision rights is...

In this paper, we propose a system for aspect-based sentiment analysis (ABSA) by incorporating the concepts of multi-objective optimization (MOO), distributional thesaurus (DT) and unsupervised lexical induction. The task can be thought of as a sequence of processes such as aspect term extraction, opinion target expression identification and sentiment classification. We use MOO for selecting th...

Aspect Term Extraction (ATE) identifies opinionated aspect terms in texts and is one of the tasks in the SemEval Aspect Based Sentiment Analysis (ABSA) contest. The small amount of available datasets for supervised ATE and the costly human annotation for aspect term labelling give rise to the need for unsupervised ATE. In this paper, we introduce an architecture that achieves top-ranking perfor...

Aspect Oriented language aims to make cross-cutting concerns clearly identifiable with special linguistic construct called aspects. In order to analyze the properties of an aspect one should consider the aspect itself and the part of the system it affects. This part is just a slice of the entire system and can be extracted by exploiting program slicing algorithms. However they will behave corre...
