Network has become the key method to analysis the interacting targets. The Baidu Baike entry network was constructed by means of Baidu Baike entry related terms and term category attributes. And then according to the feature of the closely connection in communities and the sparsely connection between communities in organization structure, it can reveal the relationship between the different entries...
With the development of Internet, personalized services have been widely used. Especially, personalized search are getting more and more attention. Aiming at improving the effectiveness of existing methods of personalized search, this paper proposes a method of generating interactive environment which provides semantic background for a search session. Interactive environment involves two aspects of...
Personalized Web search is an effective means of providing specific results to different users when they submit the same query. How to obtain user's real-time information need is a key issue in personalized search. Existing methods concentrate more on the building user profile based on Web pages/documents which affects the efficiency of search engine. In addition, dynamics of user profile is often...
At present, object-extraction is one of the key problems of the data-procession to the aerial LIDAR dataset. The aim of this paper is to research the methods to classify and extract the object-points from the cloud points obtained by the aerial LIDAR system. In this paper, based on the different feature of elevation and intensity of different objects, the laser-points of buildings, vegetation and...
Bag of visual words model has shown interesting capabilities of object category recognition. Considering that there is different discriminative ability of each visual word for object categorization, we propose a novel method based on maximization of mutual information to measure the discriminative ability of words and then give a visual vocabulary optimization algorithm based on more discriminative...
Clouding computing is considered as one of the most promising computing paradigms. Most already existing systems, which provide cloud computing, only pay attention to aggregating resources with the same computing capability and provide user with local optimized and discontinuous results. To satisfy users' complex requirements it's necessary to orchestrate resources with different functions together...
