The shared task on Aspect based Sentiment Analysis primarily focuses on mining relevant information from the thousands of online reviews available for a popular product or service. In this paper we report our works on aspect term extraction and sentiment classification with respect to our participation in the SemEval-2014 shared task. The aspect term extraction method is based on supervised lea...

In this paper we present our contribution to SemEval-2014 Task 4: Aspect Based Sentiment Analysis (Pontiki et al., 2014), Subtask 2: Aspect Term Polarity for Laptop domain. The most outstanding feature in this contribution is the automatic building of a domain-depended sentiment resource using Latent Semantic Analysis. We induce, for each term, two real scores that indicate its use in positive ...

The terminology of the optic nerve had already been changed three times, since 1895 until 1955 when the term "nervus opticus" was introduced in the "Terminologia Anatomica". Following our study we claim that, from the aspect of phylogenetic evolution of binocular vision development as well as optical embryogenesis where opticus is evidently presented as a product of diencephalic structures, the...

This paper describes our SeemGo system for the task of Aspect Based Sentiment Analysis in SemEval-2014. The subtask of aspect term extraction is cast as a sequence labeling problem modeled with Conditional Random Fields that obtains the F-score of 0.683 for Laptops and 0.791 for Restaurants by exploiting both word-based features and context features. The other three subtasks are solved by the M...

Abstract: Microwave processing is one of the novel methods for combustion synthesis of intermetallic compounds andcomposites. This method brings about a lot of opportunities for processing of uniquely characterized materials. In thisstudy, the combustion synthesis of TiAl/Al2O3 composite via microwave heating has been investigated by thedevelopment of a heat transfer model including a microwave...

Aspect-orientation has been capturing researcher’s attention for the last few years. We have seen the birth of several aspect-oriented programming techniques and also the propagation of the aspect concept to the earlier stages of the software development process, such as requirements analysis and design. Our long-term goal is to extend aspect-orientation to the business modelling activity. This...
