Agent-Based Adaptive Selection and Interaction to Z39.50 Servers
نویسندگان
چکیده
Digital libraries and OPACs are offering an enormous collection of information resources which can be accessed through Internet by quite different users thanks to the existence of standard protocols for information retrieval such as Z39.50. However, some users may find difficult to get the items they are looking for in such a huge bulk of heterogeneous resources since they have to know where and how they have to search for. Thus, one of the main reasons for the disregard of the Z39.50 service has traditionally been the absence of appropriate interfaces and the cost of making alternative searches. WAY-Z39.50 tries to help spreading the use of these servers by providing easy web access to them, as well as, by facilitating the access to multiple servers at once. The prototype described implements the WAY general model based on an agent-based architecture that provides adaptive searching in different servers through an adaptive interface.

Determination of adaptive responses of peanut genotypes and patterns of genotype × location interaction using the CSM-CROPGRO-Peanut model
The adaptive responses of crop genotypes and patterns of genotype x location (G x L) interaction are important to crop improvement as they are the basis for selection for specific adaptation and for elucidation of the causes of G x L interaction. Their legitimate assessment, however, requires yield data for the test genotypes for a large number of sites and over multiple years. Such data are se...

Many thousands of researchers are now using personal bibliographic managers such as Reference Manager, EndNote and ProCite to access bibliographic databases via the Z39.50 protocol. Using the EndNote software as an example, this paper demonstrates how researchers are using a standard search interface to access diverse databases and download references into their personal databases. There follow...
متن کاملBasic Z39.50 Server Concepts and Creation
The Z39.50 protocol is a standard network language for searching and retrieving records from remote databases. The Z39.50 client/server session model provides multiple abstract views of records, depending on whether searching, retrieval, or element selection is taking place. The underlying network stream that carries user queries, database records, diagnostics, and protocol control information ...

This paper presents an online two-stage Q-learning based multi-agent (MA) controller for load frequency control (LFC) in an interconnected multi-area multi-source power system integrated with distributed energy resources (DERs). The proposed control strategy consists of two stages. The first stage is employed a PID controller which its parameters are designed using sine cosine optimization (SCO...
