Database Support for Path Query Functions
Extending relational database functionality to include data mining primitives is one step towards the greater goal of more closely integrated database and mining systems. This paper describes one such extension, where database technology is used to implement path queries over a graph view of relational data. Partial-path information is pre-computed and stored in a compressed binary format in an...
متن کاملQuery Reformulation for Clinical Decision Support Search
One of the tasks a Clinical Decision Support (CDS) system is designed to solve is retrieving the most relevant and actionable literature for a given medical case report. In this work, we present a query reformulation approach that addresses the unique formulation of case reports, making them suitable to be used on a general purpose search engine. Furthermore, we introduce five reranking algorit...
متن کاملSemantics Driven Support for Query Formulation
In this paper we describe the principles of the design and development of an intelligent query interface, done in the context of the SEWASIE (SEmantic Webs and AgentS in Integrated Economies) European IST project. The SEWASIE project aims at enabling a uniform access to heterogeneous data sources through an integrated ontology. The query interface is meant to support a user in formulating a pre...
متن کاملDiscovering Popular Clicks\' Pattern of Teen Users for Query Recommendation
Search engines are still the most important gates for information search in internet. In this regard, providing the best response in the shortest time possible to the user's request is still desired. Normally, search engines are designed for adults and few policies have been employed considering teen users. Teen users are more biased in clicking the results list than are adult users. This leads...
متن کاملProvably-Secure Schemes for Basic Query Support in Outsourced Databases
In this paper, we take a closer look at the security of outsourced databases (aka Database-as-the-Service or DAS), a topic of emerging importance. DAS allows users to store sensitive data on a remote, untrusted server and retrieve desired parts of it on request. At first we focus on basic, exact-match query functionality, and then extend our treatment to prefix-matching and, to a more limited e...
