Problems of information search on the Internet
Janů, Tomáš ; Sklenák, Vilém (advisor) ; Šubrta, Václav (referee)
This thesis adverts to the inadequacies and impediments which can be met by an ordinary user of the internet when searching for information. The process of searching itself represents an interaction between the request given by a user and the result displayed by a search engine. The result might be in a form of URL address of a concrete web page, picture, product, location etc. Some of the problems, which are described in detail in the thesis, are for example relevance and freshness of the search result, separation of global and local result, spam in the results or problems connected to the searching in the online maps. There is an emphasis on the local market, respectively on the Czech user, in the thesis. Furthermore, it focuses on the freshness of all data and on a practical sample in a picture form. The important data and statistics are recorded in the well-arranged tables and graphs. Among others, many interesting information and observations can be found in the thesis. These information and observations are marked with the blue arrow (->).
