Spam web pages have posed great challenges to the development of search engines. The content spam is among the commonly used. Along with the development of Internet technologies, the content spam is difficult to detect. The current detection methods for the web page using content spam technique primarily rely on the statistical features, which has obvious limitations. In this article, a spam webpage...
In this paper, we design and develop a movie-rating and review-summarization system in a mobile environment. The movie-rating information is based on the sentiment-classification result. The condensed descriptions of movie reviews are generated from the feature-based summarization. We propose a novel approach based on latent semantic analysis (LSA) to identify product features. Furthermore, we find...
Most web text clustering is based on the space vector text representation model. This results in a high dimension in the terms; and it leads to an increase in time complexity and a loss of text semantics due to the fact that the semantic relationship of the terms is not considered. In this paper, a new approach is taken where a concept lattice is generated with text treated as object and terms of...
The similarity between the semantic relations that exist between two word pairs is defined as their relational similarity. For example, the semantic relation, is a large holds between the words in the word pair (lion, cat) and (ostrich, bird), because lion is a large cat, and ostrich is the largest living bird on earth. Consequently, the two word pairs, (lion, cat) and (ostrich, bird), are considered...
In this work, we investigate how to propagate annotated labels for a given single image from the image-level to their corresponding semantic regions, namely Label-to-Region (L2R), by utilizing the auxiliary knowledge from Internet image search with the annotated image labels as queries. A nonparametric solution is proposed to perform L2R for single image with complete labels. First, each label of...
Aimed at the application requirements of content-based image retrieval technology on the Internet, firstly, some key techniques and application ways are researched, then the principles and methods how to reduce the ??gap?? between low-level visual features and high-level semantic description of image are analyzed for improving the efficiency and precision of image retrieval. At last, taken several...
