Comment extraction using declarative crowdsourcing(CoEx Deco)
Kamran Shaukat, Usman Shaukat · 2016
In relational database systems declarative crowdsourcing enables the user to avoid the complexities while obtaining desired results from relation database. Our proposed system provides the user the facility to submit queries in the form of comments. In this way the user can ask for some specific information in a more expressive way and the results obtained will be more accurate and related according to the user's desire. In our presented system the user will place queries in the form of triplets. CoEx Deco is a system that will answer the user queries over a Simple Protocol and RDF Query Language (SPARQL) Query on Resource Description Framework (RDF) together obtaining data from crowd in form of triplet. We have made the user free to comment anything about a specific noun in form of triplet and our system will make a seamless integration of user entered data along with data collected from the crowd. In our presented system the user can enter the query in form of triplet and each triplet consists of a subject and an object, both labeled with a predicate. In other words we can say that the user can enter a query in the form of comments about a specific noun and each comment should contain these three things which are mentioned above. The query will be then executed and the user will get the desired results from the RDF database. RDF database is in the form of directed labeled graphs in which each edge represents a triplet. The graph matching technique is constructed by the patterns of triples. When a query is evaluated the input graph of RDF is matched against the inside variables of triple patterns. In this way the user can place more expressive queries which will be helpful in obtaining more accurate desired results.
