An integrated framework for analyzing multilingual content in Web 2.0 social media

• An integrated framework is developed for analyzing multilingual social media.
• Dark Web Forum Portal (DWFP) is developed for the security domain.
• Users supported by DWFP complete tasks better and faster.
• Participants rate DWFP to have better usability and satisfaction.

The growth of Web 2.0 has produced enormous amounts of user-generated content that contains important information about individuals' attitudes, perceptions, and opinions toward products, social events, and political issues. The volume of such content is increasing exponentially, making its search, analysis, and use more difficult and thus favoring advanced tools that aid in information search and processing. We propose an integrated framework that offers an infrastructure necessary for accessing, integrating, and analyzing multilingual user-generated content from different social media sites. Building on this framework, we develop the Dark Web Forum Portal (DWFP) that supports the gathering and analyses of social media content concerning security. Our evaluation results show that users supported by DWFP complete tasks better and faster than those using the benchmark forum. Participants consider DWFP to be better in terms of system quality, usefulness, ease of use, satisfaction and intention to use.
