CrowdSense: Open Database Concept for Data Acquisition Using Human Sensing

Abstract

Relational databases are based on the closed world assumption. When data is required from the database, it provides results only if relevant data is avail- able in the database. Closed world assumption is no longer valid when we need to get a decision or acquire knowledge on some matter that changes due to environment factors or current circumstances. Open database con- cept provide new path to obtain new data from people who have instinct and thorough knowledge in a particular domain. Expertise sense what will happen next in their eld and crowdsourcing concept is used for contact ex- pertise. To accomplish real usage of crowdsourcing, user interfaces must be designed in a simple and elegance way. Concentration must give to select perceptual organization, semiotics, text and colour of user interface to ac- quire correct and fast responses. Acquiring data using human as sensors in answering question will open new knowledge access approach.
