EFFECTIVE NAVIGATION QUERY RESULTS BASED ON BIOMEDICAL DATABASE

P.RAMYA, DR.NALINI

Search queries on biomedical databases, such as Pub Med, frequently return a large number of results, only a small subset of which is applicable to the user. Classification and cataloging, which can also be united, have been suggested to improve this information overload problem. Result optimization and results categorization for biomedical databases are the focus of this work. A natural way to establish biomedical credentials is affording to their Mesh annotations. Mesh is a inclusive concept hierarchy used by Pub Med. In this paper, we present the BioIntelR (BIR) system, adopts the BioNav system enables the user to revolve large number of query results by organizing them using the Mesh concept hierarchy. First, BioIntelR (BIR) system prompts the user for the exploration criteria and the system automatically connects to a middle layer created at the application level which directs the query to the proper valid query path to select correct criteria of the search result from the biomedical database. The query results are organized into navigation tree. At each node expansion step, BIR system exposes only a small subset of the concept nodes, preferred such that the predictable user navigation cost is minimized. In disparity, to the previous systems, the BIR system outdoes and optimizes the query result time and reduces query result set for easy user navigation, Data Warehousing.
