L'objet de notre étude est la requête adressée à un moteur de recherche Web par un usager dans le cadre d'une recherche d'information. Nous souhaitons mieux comprendre l'étape de la recherche d'information située entre le besoin d'information et la formulation / reformulation de la requête. Notre thèse est articulée autour de deux hypothèses de recherche. D'abord, nous avons émis l'hypothèse qu'une requête adressée à un moteur de recherche Web peut receler de l'implicite. Ensuite, nous avons considéré que ce contenu implicite peut être utilisé par les usagers dans des tactiques de formulation / reformulation de la requête. Nous avons notamment analysé le discours de 61 étudiants que nous avons interrogés sur leur intention de recherche. Ce discours était principalement constitué d'un niveau sémantique (qui décrit le thème de la recherche) et d'un niveau pragmatique (composé d'un but seul ou d'un but ou plusieurs sous-but(s)). Les termes représentant le niveau sémantique pouvaient être complètement ou partiellement formulés dans la requête, mais ceux représentant le niveau pragmatique n'étaient généralement pas formulés. Cette situation de communication s'apparente à une négociation entre le moteur de recherche et l'usager. Le moteur de recherche tente de disposer d'éléments sur le besoin d'information de l'usager et ce dernier tente d'obtenir à partir d'un contenu explicitement formulé dans sa requête, un ensemble d'information afin de progresser sur la résolution de son problème / The object of our study is the query, sent to a Web search engine, by an Internet user. We aim to reach a better understanding of the phase of information seeking located between the information need and the query formulation. Our thesis is based on two core hypotheses, all related to the query. Firstly, we considered that the query expressed partially the user’s information need and therefore contain an implicit part. Secondly, we also considered that the implicit part can be used by the users in their query formulation tactics. We notably analyzed 61 students’ speech about their search intent. The speech was based mainly on a semantic level (the terms representing the topic of the research) and a pragmatic level (composed of an only purpose or purpose and of many under purposes). The terms representing the semantic level could be rather completely or partially formulated in the query but those representing the pragmatic level weren’t formulated. This situation of communication is similar to a negotiation between the Web search engine and the user. The search engine Web tries to have elements on user’s information need and the user tries to obtain, from a contents explicitly formulated in his query, a set of information in order to progress on his resolution of its problem

The practical part includes the brief description of the computer and console games market in the Czech Republic; analysis of the online shop with computer and console games operated by GameLeader, s.r.o.; and the improvement suggestions for the current online presentation of considered company is presented. Finally, the online Inbound Marketing strategy solution is introduced to be implemented by GameLeader, s.r.o. company.

In current business affairs, most executive professions require one or several kinds of data consultation in their practice. Nowadays, the majority of data either is or has been digitalized and digital data is defined as information represented in a discrete and discontinuous manner. For accessibility purposes, data are often stored in databases that organize information via design and modeling techniques to facilitate querying. Data retrieval is crucial and if this process lacks efficacy, users either are presented incomplete information or are forced to perform repetitive queries. Intellectual property (IP) lawyers in Brazil are among that group and must regularly access a private database for trademark information. While it contains all the data they require, the database’s querying mechanisms are not tailored for IP law practice. The existing filters and lack of replacement algorithms often yield incomplete results, increasing time and resources dispended. With millions of dollars in potential lawsuits and work-hours, the purpose of this study is to investigate whether an IP-focused querying system could help mitigate this resource waste, facilitating the trademark comparison work of IP lawyers. For this, a new orthographic and phonetically focused querying logic was implemented. ANOVA tests and a questionnaire were used to compare the existing querying mechanism with the new one in terms of time, work satisfaction and querying accuracy. Results indicate the new querying system significantly decreased the amount of searches needed to execute a complete trademark analysis, while lawyers averaged the same amount of time to complete their work. Lawyers also reported higher work satisfaction levels and perceived increase in work efficiency.

This thesis deals with the problem of searching of structures in large chemical compounds databases. The aim is to design and implement an efficient system that supports two basic types of search, which are identity and substructure search. This task is complicated not only by the large number of entries in databases but also by graph representation of chemical structures, for which many algorithms are hard to solve. The thesis will introduce concepts which will prove useful in solving these problems. A web service is also created as a part of the thesis in order to make the database searching available to the users.

Internet trading had became common part of life to many people. Link to that walks also publicity that step by step moves from classical media to on-line formats.

The purpose of this thesis is a summary of theoretical knowledge in the field of information retrieval. This document contains mathematical models that can be used for information retrieval algorithms, including how to rank them. There are also examined the specifics of image and text data. The practical part is then an implementation of the algorithm in video shots of the TRECVid 2009 dataset based on high-level features. The uniqueness of this algorithm is to use internet search engines to obtain terms similarity. The work contains a detailed description of the implemented algorithm including the process of tuning and conclusions of its testing.
