In aspect-based sentiment analysis, extracting aspect terms along with the opinions being expressed from user-generated content is one of the most important subtasks. Previous studies have shown that exploiting connections between aspect and opinion terms is promising for this ta
Unsupervised acquisition of domain aspect terms for Aspect Based Opinion Mining
The automatic analysis of opinions, which usually receives the name of opinion mining or sentiment analysis, has gained a great importance during the last decade. This is mainly due to the overgrown of online content in the Internet. The so-called aspect based opinion mining syst
UNITOR: Aspect Based Sentiment Analysis with Structured Learning
In this paper, the UNITOR system participating in the SemEval-2014 Aspect Based Sentiment Analysis competition is presented. The task is tackled exploiting Kernel Methods within the Support Vector Machine framework. The Aspect Term Extraction is modeled as a sequential tagging ta
AUEB-ABSA at SemEval-2016 Task 5: Ensembles of Classifiers and Embeddings for Aspect Based Sentiment Analysis
This paper describes our submissions to the Aspect Based Sentiment Analysis task of SemEval-2016. For Aspect Category Detection (Subtask1/Slot1), we used multiple ensembles, based on Support Vector Machine classifiers. For Opinion Target Expression extraction (Subtask1/Slot2), we
V3: Unsupervised Generation of Domain Aspect Terms for Aspect Based Sentiment Analysis
This paper presents V3, an unsupervised system for aspect-based Sentiment Analysis when evaluated on the SemEval 2014 Task 4. V3 focuses on generating a list of aspect terms for a new domain using a collection of raw texts from the domain. We also implement a very basic approach
Implicit Aspect Indicator Extraction for Aspect based Opinion Mining
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 ta
DAOP-ADL: An Architecture Description Language for Dynamic Component and Aspect-Based Development
Architecture description languages deal with the description, analysis and reuse of software architectures. This paper describes DAOP-ADL, a componentand aspect-based language to specify the architecture of an application in terms of components, aspects and a set of plug-compatib
Aspect-Oriented Analysis: a MDA Based Approach
Actually, there are many approaches to deal with crosscutting concerns in early stages in software development. One is MDSOC, which promotes the encapsulation of all relevant kinds of concerns (dimensions) and their integration. MDSOC starts from an initial problem decomposition
SINAI: Voting System for Aspect Based Sentiment Analysis
This paper describes the participation of the SINAI research group in Task 4 of the 2014 edition of the International Workshop SemEval. This task is concerned with Aspect Based Sentiment Analysis and its goal is to identify the aspects of given target entities and the sentiment e
TGB at SemEval-2016 Task 5: Multi-Lingual Constraint System for Aspect Based Sentiment Analysis
This paper gives the description of the TGB system submitted to the Aspect Based Sentiment Analysis Task of SemEval-2016 (Task 5). The system is built on linear binary classifiers for aspect category classification (Slot 1), on lexicon-based detection for opinion target expressio
