In this thesis, we provide an implementation of prioritized queries using the Google SOAP Search API. These prioritized queries are generated from the parsing of valid prioritized constraint expressions (PCE). Prioritized constraint expressions use two unary operators ( μ and ω ) to enhance an infinitesimal logic framework to allow preferential constraints and backup constraints respectively. The Perl CGI algorithm parses valid prioritized constraint expressions using a grammar and then generates a prioritized list of standard Google search queries. These standard Google queries are sent one at a time to Google via the Google SOAP Search API. The results of the search are returned as structured data to the user with their associated Truth value.

In practice, most approaches for text error detection and correction are based on a conventional domain-dependent background dictionary that represents a fixed and static collection of correct words of a given language and, as a result, satisfactory correction can only be achieved if the dictionary covers most tokens of the underlying correct text. Again, most approaches for text correction are for only one or at best a very few types of errors. The purpose of this thesis is to propose an unsupervised approach to detecting and correcting text errors, that can compete with supervised approaches and answer the following questions: Can an unsupervised approach efficiently detect and correct a text containing multiple errors of both syntactic and semantic nature? What is the magnitude of error coverage, in terms of the number of errors that can be corrected? We conclude that (1) it is possible that an unsupervised approach can efficiently detect and correct a text containing multiple errors of both syntactic and semantic nature. Error types include: real-word spelling errors, typographical errors, lexical choice errors, unwanted words, missing words, prepositional errors, article errors, punctuation errors, and many of the grammatical errors (e.g., errors in agreement and verb formation). (2) The magnitude of error coverage, in terms of the number of errors that can be corrected, is almost double of the number of correct words of the text. Although this is not the upper limit, this is what is practically feasible. We use engineering approaches to answer the first question and theoretical approaches to answer and support the second question. We show that finding inherent properties of a correct text using a corpus in the form of an n-gram data set is more appropriate and practical than using other approaches to detecting and correcting errors. Instead of using rule-based approaches and dictionaries, we argue that a corpus can effectively be used to infer the properties of these types of errors, and to detect and correct these errors. We test the robustness of the proposed approach separately for some individual error types, and then for all types of errors. The approach is language-independent, it can be applied to other languages, as long as n-grams are available. The results of this thesis thus suggest that unsupervised approaches, which are often dismissed in favor of supervised ones in the context of many Natural Language Processing (NLP) related tasks, may present an interesting array of NLP-related problem solving strengths.

The aim of this thesis is to describe in detail the current ways of optimizing websites for search engines (SEO) and to apply them in a broader marketing strategy of italian restaurant La Casa Degli Amici. The thesis presents evidence about the importance of SEO for marketing and can be used as a template for optimizing you own website. This thesis is divided into two main parts - theoretical and practical. The theoretical part explains the concepts used in the design and implementation of the practical part. The theoretical part considers 3 main subjects - search engine, users and SEO which represents website creation and optimization. This thesis describes the history of search engines and the way search engines analyze and evaluate a website. It also describes user search strategies and the way users read the search results. In the SEO section we show its advantages, brief history, SEO strategies and description of techniques and tools that can be used for SEO. In the practical part we put together a marketing strategy which consists of website creation, implementation of selected SEO techniques and social network marketing. Implementation of the marketing strategy is evaluated on data obtained during the period between 1. 8. 2016 and 31. 11. 2016.

The thesis Use of Web 2.0 technologies in education introduces the concept of Web 2.0 and its basic characteristics. The first chapter is based on the explanation of major tools and technologies labelled as Web 2.0. The second chapter deals with specific services which have already found its place in education process. The same chapter evaluates the ways of dealing with their appropriate use, particularly in higher education. This chapter contains also the examples of successful use in education. The thesis is mainly concerned about using Web 2.0 tools in the environment of Czech schools. As Web 2.0 services are not new, I asked students and teachers at the University of Economics in Prague and asked what experience they have with such instruments in their personal life, so in context of education. The third chapter is entirely devoted to survey the use of Web 2.0 tools in the practice of The University of Economics in Prague. Content of the final chapter is a reflection of what direction the web will evolve in the coming years. It also evaluates social issues associated with the turbulent development of the Internet and Web 2.0.
