Rumor Detection Based on Attention CNN and Time Series of Context Information

نویسندگان

چکیده

This study aims to explore the time series context and sentiment polarity features of rumors’ life cycles, how use them optimize CNN model parameters improve classification effect. The proposed is a convolutional neural network embedded with an attention mechanism information. Firstly, whole cycle rumors divided into 20 groups by algorithm each group texts trained Doc2Vec obtain text vector. Secondly, SVM used group. Lastly, spatial classification. experiment results show that introduced very effective for rumor detection, can greatly reduce number iterations training as well. accuracy, precision, recall F1 are better than latest benchmark model.

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

Attention-based CNN Matching Net

In this paper, we introduce attention-based CNN matching net (ACM-Net), an end-to-end neural network for question answering. ACM-Net matches between the given passage, query and multiple answer choices, and then it extracts features from passage and choices based on query information. We also propose a two-staged CNN architecture and a query-based attention mechanism in our model. These two com...

Call Attention to Rumors: Deep Attention Based Recurrent Neural Networks for Early Rumor Detection

Œe proliferation of social media in communication and information dissemination has made it an ideal platform for spreading rumors. Automatically debunking rumors at their stage of di‚usion is known as early rumor detection, which refers to dealing with sequential posts regarding disputed factual claims with certain variations and highly textual duplication over time. Œus, identifying trending ...

Discrimination of time series based on kernel method

Classical methods in discrimination such as linear and quadratic do not have good efficiency in the case of nongaussian or nonlinear time series data. In nonparametric kernel discrimination in which the kernel estimators of likelihood functions are used instead of their real values has been shown to have good performance. The misclassification rate of kernel discrimination is usually less than ...
