Abstract:
User intent may be inferred from mouse movements made within a user interface. Client-side instrumentation may be provided that collects mouse movement data that is provided to a classification engine. The classification engine receives the mouse movement data and creates a mouse trajectory. The mouse trajectory may be split into segments, and features associated with each segment may be determined. Features representing the context of the search, that is, content of the search result page, previous queries submitted, and interaction features such as scrolling, may be included. By examining the features associated with the mouse trajectories within the context of a search session, the user intent may be classified into categories using machine learning classification techniques. By inferring user intent, Web search engines may be able to predict whether a user's intent is commercial and tailor advertising accordingly.
A method of isolation of nucleic acids from a biological sample of cells comprising a combination of a solid phase cell nuclei isolation procedure with a solid phase nucleic acid isolation method.
Device For Sample Collection, Transportation, And Processing
The invention provides methods and kits for nucleic acid purification and fragment selection and recovery. By adjusting salt concentrations and/or pH of the binding buffers, only nucleic acid fragments with desired size ranges are able to reversibly and non-specifically bind to a solid surface in certain salt concentrations and/or pH conditions, and can be subsequently eluted and/or recovered from the solid surface in water and/or a low salt eluting buffer.
