Interface features of semantic web search engine

Even many current search engines have put a lot of effort to improve the quality of their system, yet the user still facing difficulties in doing their search activity. The problem is actually related to an issue of how easy to use the application, which is referring to usability matter. Therefore, in this paper we made a brief survey on existing semantic search engine (SSE) with the focus to reveal the predominant and prevalent features used in the interface design. Eight SSE was selected and a list of all features used by current SSE is presented. The finding shows that most of SSE have a simple search box, clean and clear search screen, have image results and highlighted keyword in snippet view. In the discussion part, we also highlighted some of the significant features and design guidelines that comply with usability principles for designing SSE user interface.
