Interface options offered to users for extracting content from information repositories such as YouTube are 1-dimensional. Users are presented with ubiquitous flat lists of content in menus and result lists, from which they must identify interesting content. Previous work has concentrated on the areas of user profiling and content filtering in order to retrieve and present relevant content to u...

We present a method to help a user redefine a query suggesting a list of similar queries. The method proposed is based on clickthrough data were sets of similar queries could be identified. Scientific literature shows that similar queries are useful for the identification of different information needs behind a query. Unlike most previous work, in this paper we are focused on the discovery of b...

In recent years there has been renewed activity in the literature concerning the 1,3-dipolar cycloaddition reaction (1,3-DCR) of organic azides (R-N₃) with alkynes (R'-C≡CH) to form 1,2,3-triazoles, i.e. the Huisgen synthesis. The use of catalytic Cu(I) leads to a dramatic rate enhancement (up to 10(7)-fold) and exclusive synthesis of the 1,4-disubstituted 1,2,3-triazole product. The reaction, ...

Understanding user browsing behavior in web search is key to improving web search effectiveness. Many click models have been proposed to explain or predict user clicks on search engine results. They are based on the probabilistic graphical model (PGM) framework, in which user behavior is represented as a sequence of observable and hidden events. The PGM framework provides a mathematically solid...

The popular generalized second price (GSP) auction for sponsored search is built upon a separable model of click-through-rates that decomposes the likelihood of a click into the product of a “slot effect” and an “advertiser effect”—if the first slot is twice as good as the second for some bidder, then it is twice as good for everyone. Though appealing in its simplicity, this model is quite susp...

The clawed frog Xenopus laevis uses sexually dimorphic vocalizations, mate calling and ticking, to advertise reproductive state. The basic unit of vocalization is a brief click, produced by the movement of cartilagenous disks located within the larynx. The rate of click production in the male-specific mate call (71 Hz) is an order of magnitude faster than the rate of click production in female ...

Persian language is one of the most widely used languages in the Web environment. Hence, the Persian Web includes invaluable information that is required to be retrieved effectively. Similar to other languages, ranking algorithms for the Persian Web content, deal with different challenges, such as applicability issues in real-world situations as well as the lack of user modeling. CF-Rank, as a ...

1* Min Zhao is currently researcher at NEC Lab China, Beijing. Abstract. This paper proposes a new approach to ranking the documents retrieved by a search engine using click-through data. The goal is to make the final ranked list of documents accurately represent users’ preferences reflected in the click-through data. Our approach combines the ranking result of a traditional IR algorithm (BM25)...

Brainstem auditory evoked response (BAER) was studied in term neonates using maximum length sequences (MLS), which allows presentation of acoustic stimuli at much higher rate than possible with conventional averaging technique. The response waveforms, especially for waves III and V, were well defined at the click rates of 91-455/s. Wave latencies and interpeak intervals at various click rates w...
