Towards jointly extracting aspects and aspect-specific sentiment knowledge

Proceedings of the 21st ACM international conference on Information and knowledge management, 2012
In this paper, we aim to jointly extract aspects and aspect-specific sentiment knowledge from online reviews, where the sentiment knowledge refers to the aspect-specific opinion words along with their aspect-aware sentiment polarities. To this end, we propose a Joint Aspect/Sentiment model (JAS). JAS detects aspect-specific opinion words by integrating

Physicochemical aspects of fluid extraction

Fluid Phase Equilibria, 1983
Abstract The present review considers some physicochemical properties of fluid mixtures that are important for fluid extraction, supercritical fluid chromatography (SFC) and other applications. Firstly, the most important types of phase diagrams involving liquid-gas, liquid-liquid and gas-gas equilibria are treated.

Extraction instrumentale difficile : Aspects obstétricaux

2011
L’extraction instrumentale reste un mode d’aide a l’expulsion frequent. En France, 12 % des naissances se font par voie basse instrumentale, 4,8 % par ventouse, 3,7 % par forceps et 3,5 % par spatules. L’extraction instrumentale doit etre sans danger pour la mere et le fœtus, a condition de respecter certaines regles et de ne faire que des applications

Extracting updating aspects from version differences

Proceedings of the 2008 AOSD workshop on Linking aspect technology and evolution, 2008
Dynamic software evolution represents a viable technique to update software systems at run-time. On-the-fly updating is particularly helpful for systems that must be continuously available and up-to-date. Updates consist of several incremental changes that must be applied to a system.

Some Aspects of Metal Extraction

1983
Metal extraction is usually referred to as hydrometallurgy and it deals with extraction of metals from acidified aqueous solutions. For this purpose the aqueous solution, that is the raffinate phase, is contacted with an organic extract phase. However, since metal ions are insoluble in organic solvents, the latter must contain a water-insoluble ...

Technological Aspects of Jatropha Oil Extraction

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2009
The technology of the extraction process of jatropha oil from its seeds using a solvent extraction technique was studied. The extraction process was carried out at room temperature using solvent-to-solid ratios ranging from 2 to 5 L/kg in a single and two successive stages.
