Čejka, Marek ; Souček, Martin (advisor) ; Krčál, Martin (referee)
This diploma thesis discusses a modern concept of information retrieval and search engines for libraries and other academic institutions. The concept named "web scale discovery" comprises of search engines, whose main characteristics lie in simplicity and user friendliness for the end users while maintaining all functional qualities of traditional research databases. Users can search in a wide variety of international research databases, and also in local sources of an institution that are combined within a large central index. The theoretical section presents definitions of web scale discovery, which conceptually set the new method of information retrieval within the field of information and library science. A graphic scheme of the basic functionality of a web scale discovery system is presented. Also discussed are requirements for a modern discovery system, an overview of the current situation in the Czech Republic, and a short characteristic of commercially available discovery systems. The theoretical part concludes with a literature review of selected foreign research, studying user satisfaction with the new solution, the impact on electronic and print resources in libraries, and usability testing. The practical part presents an original research study - usability testing of EBSCO Discovery...

New Generation Search Engines
Čejka, Marek ; Stöcklová, Anna (advisor) ; Souček, Martin (referee)
This thesis introduces a new method of information retrieval and search engines of a new generation which provide it. The opening chapter introduces the new concept of searching and information retrieval, called "web scale discovery", and defines the so called web scale discovery services as services that quickly search through a large central index of content compiled from both electronic databases and local library collections using a single simple search interface. It is also explained how central indexes are produced and what their main disadvantages are. The core of the thesis is first dedicated to presenting and analysing individual selected commercial web scale discovery services and then comparing them in terms of functional capabilites. Presented are the following services: EBSCO Discovery Service, Primo and Summon. A chapter for each of the services begins with a brief overview, which is followed by a description of their central index and its content, and then presents individual features on an example of a working implementation of the service. Each chapter is concluded with a summary of the most distinctive features. The last chapter compares support of selected functions in analyzed search engines using tables and supplementary commentary. The conclusion summarises gained knowledge...
