Optimally increasing the catalytic activity of Co3O4‐based materials is crucial for promoting their practical applications for acetone detection; however, this still remains challenging. Herein, a strategy is proposed in this work to increase the catalytic activity of Co3O4 toward the oxidation of acetone through the synergistic effect of boron doping and chemical reduction, which can substantially...
Query answering system (QA) has become an important branch of nature language processing (NLP) and information retrieval (IR), it encompasses a wide range of topics related to the storage and retrieval of all kinds of media. This paper presents a new combination of IR grammars, Latent Dirichlet Allocation (LDA) grammars Doc2Vec models and Deep Learning models to improve the value of Mean Reciprocal...
Each user session in an e-commerce system can be modeled as a sequence of web pages, indicating how the user interacts with the system and makes his/her purchase. A typical recommendation approach, e.g., Collaborative Filtering, generates its results at the beginning of each session, listing the most likely purchased items. However, such approach fails to exploit current viewing history of the user...
