Efficient Deep Learning Approach for Dimensionality Reduction using Micro blogs from Big data

Mr. M. Vengateshwaran
2017 International Journal for Research in Applied Science and Engineering Technology  
To improve the result of dimensionality reduction, we take advantage of the semantic similarity derived from two types of micro blog specific information, namely the retweet relationship and hash tags.  ...  In this project, we apply deep learning networks to map the high-dimensional representations of micro blog texts to low-dimensional representations.  ...  Enriching Short Text Representation in Liu Social media websites allow users to exchange short texts such as Tweets in microblogging, user status in friendship networks.  ...

Automatic Rumor Detection on Microblogs: A Survey [article]

Juan Cao, Junbo Guo, Xirong Li, Zhiwei Jin, Han Guo, Jintao Li
2018 arXiv   pre-print
Many efforts have been taken to defeat online rumors automatically by mining the rich content provided on the open network with machine learning techniques.  ...  While the openness and convenience features of social media also foster many rumors online. Without verification, these rumors would reach thousands of users immediately and cause serious damages.  ...  As for the weights of the rest two types of links: links from users to messages and links from messages to events, are not defined and set as 1 by default.  ...
