Development of document tracing system in scientific research management

A searching algorithm based on the position of Key words is proposed,and basing on this algorithm,the design and realization of Web document tracing system automatically is discussed.In this system,the user is asked to set interesting words,then read and evaluate parts of the search results,the system will understand the user′s requirement and automatically run at the given time interval.In brief,documents that users have read,to read,as well as new documents searched in most recent time are marked clearly,which can save the time of the user.The system proposed here is suitable for all kinds of people.And the algorithm can also be considered as a key technology for developing personalized intelligent search engine.
