Purpose: Identification of methods and tools of improving the quality of information on websites. The investigated instruments, techniques and mechanisms are described with regard to solving problems of the information quality from the user's perspective. Design/methodology/approach: Literature studies along with analysis of tools of improving the quality of information on websites. The analysis of tools for improving the quality of information was conducted within four areas: information integration, information validation, providing context of information, as well as adjusting information to be used. The presented examples concern, among others, information websites, government sites, online auctions and search engines, and are of cross-cutting nature. Findings: The presented tools aggregate information, enable verification of its correctness, provide both context and adjusting information to be used, which significantly affects the possibility of solving problems with information quality. For information should be: current, error-free, written objectively, having recourse to its origin, and easy to apply. Operationalization of the presented tools may be realized by means of summaries, tables of content, highlights in the content, infographics (information integration), or tag clouds, site maps, filters (information categorization). Verification of the reliability of information sources is enabled by methods of assessing information quality, whereas feedback and opinions provided by the users verify the quality of products along with the credibility of sellers. The important group of tools are so-called contextualizes of information which concern the kind of available piece of information, when it was used, its origin, when it was created/published/updated, or the author's references/qualification. Adding meta-information improves significantly the particular piece of information's context of use. More advanced flexible information presentation methods enable to improve the relevance of information retrieval results, the suggestion and completion mechanism accelerates the information retrieval process, whereas the automatic notifications call the user to action based on his/her interests and needs. Research limitations/implications: The cross-sectoral nature of the presented examples is the limitation of the conducted research. Further, practical, research will enable identification of new methods and tools in order to improve the information quality in websites. Practical implications: Knowing the tools mentioned in this article is crucial, especially for information users, for it improves the quality of acquired information. Poor information quality may lead to wrong decisions which may cause multiple negative consequences. Originality/value: Identification and examples of tools for improving the quality of information on websites from the user's perspective. This paper is addressed to all those interested in theoretical and practical research on information quality, i.e., producers, providers and information suppliers, administrators and those responsible for taking care of websites, but, most of all, their users.(original abstract)
