Trust and Doubt Terms in Financial Tweets and Periodic Reports [pdf]Paper  abstract   bibtex   
In this paper we present a study on expressions of trust and doubt in financial tweets and official periodic reports of companies. We use the trust and doubt wordlists that we created and analyze the presence of trust and doubt terms in both textual collections after some domain-specific text processing. In tweets, we have found that doubt is more frequently expressed than trust and forms higher peaks. Next, we have analyzed the relation between the filing dates of reports and the peaks in financial tweets with regard to their overall volume, trust tweets volume and doubt tweets volume. The analysis indicates that the Twitter community reacts more often to the quarterly than yearly reports and that the peaks are usually at the day of report, not before or after. As a result of corresponding analysis of textual content in annual reports, we present the frequencies of different trust/doubt terms in these reports and indicate some notable differences among their use by different companies.
