A dual relation-encoder network for aspect sentiment triplet extraction

Neurocomputing
Aspect sentiment triplet extraction (ASTE) combines several subtasks of aspect-based sentiment analysis, which aims to extract aspect terms, opinion terms, and their corresponding sentiment polarities in a sentence. The interaction relations between words have strong cueing information.

Perspective: OLED Displays Singing with the Blues

Advanced Materials, EarlyView.
While blue pixels consume approximately 50% of the energy of OLED display front planes, in the 25 years since their invention, 100% internal efficiency triplet‐controlled phosphorescent OLEDs have not met the stability standards necessary for their adoption.

Exploring the World of Double Nanohoops

Angewandte Chemie International Edition, EarlyView.
As two conjugated nanohoops covalently linked by a central unit, double nanohoops are a relatively new class of strained nanocarbons with different properties to single nanohoops. This review gives an overview of all reported double nanohoops, categorizing their structures, syntheses, and discussing properties and applications. Creativity and synthetic

Annotating aspects in text and image: A new task and dataset for multimodal aspect‐based sentiment analysis

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Aspect‐Based Sentiment Analysis (ABSA) has evolved from textual analysis to a multimodal paradigm, integrating visual information to capture nuanced sentiments. Despite advancements, existing Multimodal ABSA (MABSA) research remains limited in granularity, which focuses on either coarse‐level categories or named entities, neglecting fine ...

Multi-task Neural Network for Non-discrete Attribute Prediction in Knowledge Graphs

, 2017
Many popular knowledge graphs such as Freebase, YAGO or DBPedia maintain a list of non-discrete attributes for each entity. Intuitively, these attributes such as height, price or population count are able to richly characterize entities in knowledge ...

Balancing allocative and dynamic efficiency with redundant R&D allocation: The role of organizational proximity and centralization

Strategic Management Journal, EarlyView.
Abstract Research Summary Resource‐based‐view scholars have mainly examined two resource allocation approaches for competitive advantage in multiunit firms: resource sharing and resource redeployment. These approaches emphasize allocative efficiency—the optimal allocation of resources to maximize their current value. In technology‐intensive industries,
