摘要： 针对用户使用搜索引擎输入关键词查询信息时,由于输入法的原因或者不小心输入错误关键词等,致使搜索结果不符合用户预期的问题,提出基于搜索引擎日志的中文纠错方法。首先对用户网络日志展开研究,对数据进行预处理,将用户常见错误分为两大类:一类为拼音引起的错误,针对该类错误,参考并改进了基于拼音索引的中文模糊匹配算法进行纠错;另一类为多字、少字、异位及别字引起的错误,针对该类错误,设计了模糊匹配方法结合最小编辑距离方法进行纠错。经过实验验证,证明了该纠错方法的有效性,该方法能够一定程度上提升用户体验,满足实际工程需要。

关键词： Web search engine   Cognitive biases   Information retrieval   Hypothesis testing   Man-machine interaction  

摘要： The widespread use of online search engines to answer the general public's needs for information has raised concerns about possible biases and the emerging of a 'filter bubble' in which users are isolated from attitude-discordant messages. Research is split between approaches that largely focus on the intrinsic limitations of search engines and approaches that investigate user search behavior. This work evaluates the findings and limitations of both approaches and advances a theoretical framework for empirical investigations of cognitive biases in online search activities about health-related topics. We aim to investigate the interaction between the user and the search engine as a whole. Online search activity about health-related topics is considered as a hypothesis-testing process. Two questions emerge: whether the retrieved information provided by the search engines are fit to fulfill their role as evidence, and whether the use of this information by users is cognitively and epistemologically valid and unbiased.

摘要： The main objective of this work is to analyse the contributions of Judit Bar-Ilan to the search engines studies. To do this, two complementary approaches have been carried out. First, a systematic literature review of 47 publications authored and co-authored by Judit and devoted to this topic. Second, an interdisciplinarity analysis based on the cited references (publications cited by Judit) and citing documents (publications that cite Judit's work) through Scopus. The systematic literature review unravels an immense amount of search engines studied (43) and indicators measured (especially technical precision, overlap and fluctuation over time). In addition to this, an evolution over the years is detected from descriptive statistical studies towards empirical user studies, with a mixture of quantitative and qualitative methods. Otherwise, the interdisciplinary analysis evidences that a significant portion of Judit's oeuvre was intellectually founded on the computer sciences, achieving a significant, but not exclusively, impact on library and information sciences.

摘要： Search engine optimisation is an important aspect for every business. There are different features and methods to it and they evolve over the years as there are created new algorithms and software updates. At the moment, voice search is a topical matter and there are done many predictions and speculations of the future of it. This makes the subject interesting to research further. The purpose of this thesis is to study what are the current trends in SEO, how voice search affects SEO and what is the role of voice search now and in the future. It will be also studied if it is true that voice search will grow as popular as traditional search and if it eventually be the only way of searching on search engines. The theme is limited to search engine Google, voice search optimisation and the future of voice search. Meaning that there will be introduced the technology enabling voice search but not explained thoroughly how voice search is optimised for different digital assistants nor other software applications. Search Engine Advertising (SEA) is excluded from the research because it is a small part of Search Engine Marketing (SEM) and the main focus is only on unpaid organic search SEO. The theoretical part concentrates on SEO trends on Google and voice search in the USA and Europe. Whereas, in empirical part is highlighted the situation and future of voice search in Finland. To answer the research questions there was conducted a qualitative research by interviewing four SEO professionals. The professionals were selected because of their long experience in SEO and marketing field. The interviews were carried out on 31 March 2020, 2 April 2020 and 8 April 2020. The topic of the thesis is rather new and therefore there had to be gathered more in-depth data which qualitative research method enables to do. It was found out that there are many SEO trends in search engine optimisation. However, the trends that were mentioned now to be the most important ones are high-quality tru

摘要： Educational games have been adopted in different disciplines in light of their various advantages such as engaging students and promoting learning attitudes, but their applications in Information Systems Education are relatively limited. In response to the needs for establishing new methodologies of Information Systems (I.S.) education, this study aims to explore the potential impact of educational games in I.S. education. We designed and adopted an educational game for teaching and learning of search engine optimization (SEO) based on previous articles about game-based learning (GBL). The game was played by a group of undergraduate students in a digital marketing course to learn SEO concepts. Survey and focus groups were used to collect their feedback to study the roles of educational games in students' learning. Recommendations on designing and adopting educational games for students' learning in Information Systems are also provided.
