Community question answering(CQA) websites such as Quora and StackOverflow provide a new way of asking and answering questions which are not well served by general web search engines. With the huge volume and ever-increasing number of users and questions, effective strategies of ranking experts for different questions need to be proposed. In this paper, we first make some analysis on the network structure...
This paper presents a method of related subject of Tibetan web integrating content evaluation and link analysis. The analysis of related subject of Tibetan web is the most important part of the special Tibetan Search. It guide web crawler download pages accurate and efficient. The content evaluation of this method extends the VSM based on keyword, it consider that the keywords in the page have different...
Task Analysis techniques models the human activity for the computer based systems. The role of task analysis is vital in the interface design. In recent years, various task analysis techniques have been explored by the researchers, which include Hierarchical Task Analysis (HTA), Cognitive Task Analysis (CTA), Link Analysis (LA), and Timeline Analysis (TA). We have explored that task analysis techniques...
Community-driven Question Answering services are gaining increasing attention with tens of millions of users and hundreds of millions of posts in recent years. Due to its size, there is a need for users to be able to search these large question answer archives and retrieve high quality content. Research work shows that user reputation modeling makes a contribution when incorporated with relevance...
A main challenge for Web content classification is how to model the input data. This paper discusses the application of two text modeling approaches, latent semantic analysis (LSA) and latent Dirichlet allocation (LDA), in the Web page classification task. We report results on a comparison of these two approaches using different vocabularies consisting of links and text. Both models are evaluated...
A link analysis model for passive UHF RFID system in LOS indoor environment is developed and demonstrated. Using this model, the power received by tag and the read performance are investigated. The multipath fading and RMS delay spread for UHF RFID system are analyzed by a 5-ray model with different polarization, e.g., horizontal polarization, vertical polarization, and circular polarization. A practical...
