![]() Experiments demonstrate the effectiveness and efficiency of the proposed method. The proposed algorithm is a natural extension from traditional search on graph methods and is more suitable for fast neural ranking. The edges connecting these types of nodes are constructed via the neural network ranking measure. BEGIN contains two types of nodes: base/searching objects and sampled queries. To tackle this challenge, in this paper, we propose to construct BipartitE Graph INdices (BE-GIN) for fast neural ranking. Traditional approximate near neighbor (ANN) search which typically focuses on metric ranking measures, is not applicable to these complex measures. Online neural network ranking, i.e., the so called fast neural ranking, is considered a challenging task because neural network measures are in general non-convex and asymmetric. Neural network based ranking has been widely adopted owing to its powerful capacity in modeling complex relationships (e.g., users and items, questions and answers). While access to Wikipedia has been intermittently blocked or certain articles filtered in China since June 2004, there is some controversy about the degree to which Baidu cooperates with Chinese government censorship. Baidu offers multimedia content including MP3 music, and movies, and is the first in China to offer Wireless Application Protocol and personal digital assistant -based mobile search.Baidu Baike is similar to Wikipedia as an encyclopedia however, unlike Wikipedia, only registered users can edit the articles. In December 2014, Baidu was expected to invest in the company Uber.Baidu provides an index of over 740 million web pages, 80 million images, and 10 million multimedia files. In December 2007, Baidu became the first Chinese company to be included in the NASDAQ-100 index. China's Internet-search revenue share in second quarter 2011 by Baidu is 76%. During Q4 of 2010, it is estimated that there were 4.02 billion search queries in China of which Baidu had a market share of 56.6%. In May 2014, Baidu ranked 5th overall in the Alexa Internet rankings. Both of the co-founders are Chinese nationals who studied and worked overseas before returning to China. Baidu was established in 2000 by Robin Li and Eric Xu. Baidu offers 57 search and community services including Baidu Baike and a searchable, keyword-based discussion forum. , incorporated on January 18, 2000, is a Chinese web services company headquartered in the Baidu Campus in Haidian District in Beijing.Baidu offers many services, including a Chinese language-search engine for websites, audio files, and images.
