“…The knowledge base (or index) is the key component in our framework. In the future, we plan to apply the mechanism of database access control in [15] and the idea of clustering algorithm in [16] to ameliorate our knowledge base, and we will optimize our algorithm for the weights of query words to improve the recalls and precisions of recommender queries. It would be interesting to consider that multiple candidate recommender queries are listed by using the auto complete techniques of the Textbox as described in [17], which will provide the conveniences for the users and increase the efficiency in refining the recommender queries.…”

According to the feedback information from a user in the result sets of initial or previous queries, we present in this paper a framework for processing recommender top-N queries in relational databases. Based on the techniques and ranking strategies of keyword search, this framework returns top-N results for an initial query given by the user. As soon as he or she selects some of the top-N results, the framework will find out related keywords from the result(s) selected by the user, calculate and modify corresponding weights of the related keywords. By using the weights, our framework determines new query words associated with the previous query to construct a recommender query. A knowledge base is created to store the related information of the tuples in the underlying database for evaluating the recommender query. The experimental results based on real datasets show the efficiency and effectiveness of our framework.

Man-hour ration is an important work in process planning, it influences on the production cost and production plan. According to the practical requirements of rotary bearing manufacturing enterprise, a function framework of man-hour ration management system is proposed in the paper. Some key techniques are discussed, involving UML modeling, man-hour calculation method based on the general procedure, automatic generation and print of man-hour report. On this basis, a man-hour ration management system of rotary bearing is developed by using object-oriented programming method and SQL Sever database technology. Finally, an application case is given, which is easy to operate, and the man-hour calculation is fast and accurate, the generated man-hour report is unified and standardize.
