Collect Meaningful Information about Stock Markets from the Web
Saleem Abuleil, Khalid Alsamara
Events represent a significant source of information on the web; they deliver information about events that occur around the world in all subjects and areas. These events can be collected and organized to provide valuable and useful information for decision makers, researchers, as well as for any person seeking knowledge. In this paper, we discuss an ongoing research to target stock markets domain to observe and record changes (events) when they happen, collect them, understand the meaning of each one of them, and organize the information along with meaning in a well-structured format. By using Semantic Role Labeling (SRL) technique, we have identified four factors for each event in this paper: verb of action and three roles associated with it, entity name, attribute, and attribute value. We have generated a set of rules and techniques to support our approach to analyze and understand the meaning of the events that take place in stock markets.
