Aspect-based sentiment analysis (ABSA) aims to identify the of an aspect in a given sentence and thus can provide people with comprehensive information. However, many conventional methods need help discover linguistic knowledge implicit sentences. Additionally, they are susceptible unrelated words. To improve performance model ABSA task, multi-task based on Bidirectional Encoder Representation ...

Aspect-based opinion mining aims to model relations between the polarity of a document and its opinion targets, or aspects. While explicit aspect extraction has been widely researched, limited work has been done on extracting implicit aspects. An implicit aspect is the opinion target that is not explicitly specified in the text. E.g., the sentence “This camera is sleek and very affordable” give...

Contract monitoring is carried out to ensure the Quality of Services (QoS) attributes and levels specified in an electronic contract throughout a business process enactment. This paper proposes an approach to improve QoS monitoring based on the aspect-oriented paradigm. Monitoring concerns are encapsulated into aspects to be executed when specific process points are reached. Differently from ot...

A long-term research goal for Aspect-Oriented Programming is the modular verification of aspects such that safe evolution and reuse is facilitated. However, one of the fundamental problems with verifying aspect-oriented programs is the inability to determine the effect of the weaving process on the control flow of the program, and thus on the state of the system and subsequently the properties ...

This paper describes our system for generating Chinese aspect expressions. In the system, the semantics of different aspects is characterized by specific temporal and conceptual features. The semantic applicability conditions of each individual aspect are theoretically represented by an aspect selection function (ASF). The generation is realized by evaluating implemented inquiries which formall...
