Aspect-level Sentiment Analysis using AS-Capsules
The Web Conference, 2019Aspect-level sentiment analysis aims to provide complete and detailed view of sentiment analysis from different aspects. Existing solutions usually adopt a two-staged approach: first detecting aspect category in a document, then categorizing the polarity

Capsule–Capsule Conversion by Guest Encapsulation
Angewandte Chemie, 2016AbstractGuest‐induced M18L6–M24L8 capsule–capsule conversion is reported. Both capsules are composed of PdII ethylenediamine units (M) and 1,3,5‐tris(3,5‐pyrimidyl)pyrimidine (L), and form trigonal bipyramidal (M18L6) and octahedral (M24L8) closed‐shell structures with huge hydrophobic inner spaces.

Journal of the American Chemical Society, 2016
We report a new methodology for producing monometallic or bimetallic nanoparticles confined within hollow nitrogen-doped porous carbon capsules. The capsules are derived from metal-organic framework (MOF) crystals that are coated with a shell of a ...

Block Copolymer Capsules with Structure-Dependent Release Behavior.
Angewandte Chemie, 2016Although high-boiling non-solvent induced macrophase separation in emulsion droplets has been widely applied for the fabrication of polymeric capsules, precise control of their structures remains a great challenge.

Current Gastroenterology Reports, 2005
Video capsule endoscopy is a major innovation that provides high-resolution imaging of the entire small intestine in its entirety. In the 4 years since its introduction, capsule endoscopy has demonstrated its viability as a first-line investigation in patients with obscure gastrointestinal bleeding after a negative esophagogastroduodenoscopy and ...
