Filed:

Apr 6, 2012

Appl. No.:

13/441489

Inventors:

Xincheng Zhang - Sunnyvale CA, US
Yefei Peng - Palo Alto CA, US

Assignee:

Google Inc. - Mountain View CA

International Classification:

G06F 3/048

US Classification:

715773

Abstract:

A computing device automatically customizes attributes of a graphical keyboard based on user inputs to the graphical keyboard. For example, the computing device can display a first graphical keyboard arrangement that includes a first representation of a key associated with a target region of an input-sensitive display. The computing device receives a plurality of user inputs, each associated with a respective touch region of the input-sensitive display. Subsequent to determining that one or more of the touch regions is not substantially aligned with the target region, the computing device displays a second graphical keyboard arrangement that includes a second representation of the key, wherein at least one attribute of the second representation of the key is graphically modified relative to the first representation of the key so as to substantially align one or more of the touch regions with a target region associated with the second representation of the key.

US Classification:

707 5, 707E17083

Abstract:

A system for generating subphrase queries. The system includes a sequence label modeling engine and a regression modeling engine. The sequence label modeling engine generates a plurality of subphrase queries by indexing through each token in a search phrase and labeling each token based on an association to other tokens in the search phrase. The regression modeling engine scores each subphrase query at least partially on the association according to a scoring model. The regression modeling engine identifies the subphrase query with the highest score which may then be used for identifying a sponsored search list or a web search item.

G06Q 30/02

Abstract:

The present disclosure discusses the adjustment of a rate of display between different types of content item categories. The system of the present disclosure can determine a content item's rate of display with a first category of content and with a second category of content. The system can determine a relationship between the display rates. If the display rates are outside of a predetermined range, the system can update the display parameters of the content categories.

Appl. No.:

14/709799

Inventors:

- San Francisco CA, US
Yefei Peng - Palo Alto CA, US

International Classification:

G06Q 10/06
G08G 1/00

Abstract:

A dispatch system is provided to collect and store historical passenger pick-up and drop-off data. The dispatch system can utilize the historical data to construct correlation models that identify spike pairs each comprising a spike in passenger drop-offs and an associated spike in passenger pick-ups at a given location. The spike pairs can be indicative of an event at an event location having a typical duration. The dispatch system can detect a current spike in passenger drop-offs at a respective event location, and predict an associated spike in pick-up requests after a given duration at the event location using the historical data and correlation models.
