When Do Users Change Their Profile Information on Twitter?

We can see profile information such as name, description and location in order to know the user on social media. However, this profile information is not always fixed. If there is a change in the user's life, the profile information will be changed. In this study, we focus on user's profile information changes and analyze the timing and reasons for these changes on Twitter. The results indicate that the peak of profile information change occurs in April among Japanese users, but there was no such trend observed for English users throughout the year. Our analysis also shows that English users most frequently change their names on their birthdays, while Japanese users change their names as their Twitter engagement and activities decrease over time.Comment: IEEE BigData 2017 Workshop : The 2nd International Workshop on Application of Big Data for Computational Social Science (accepted

Influence Analysis based on Political Twitter Data

Studies of online behavior often consider how users interact online, their posting behaviors, what they are tweeting about, and how likely they are to follow other people. The problem is there is that no deeper study on the people that a user has interacted with and how these other users affect them. This study examines if it is possible to draw similar sentiment from users with whom the target user has interacted with. The data collection process gathers data from Twitter users posting to popular political hashtags, which the highest at the time published were #MAGA and #TRUMP, as well as the tweets of people to whom they have tweeted. By applying weights based on the type of interactions as well as the amount, study how close the sentiments that the original user expressed are compared to the users they tweeted to. The weighting formula described above will be known as the Inferred Sentiment Score, or ISS for short. This study presents this scheme of gathering data to build user profiles and ISS to determine how similar a user’s sentimental expression is to the people they communicate with on Twitter. The main results of this study show that by using the ISS formula that there is a strong correlation of the sentiments expressed on Twitter by a user and the users that they communicate with
