Appl. No.:

13/228337

Assignee:

Google Inc. - Mountain View CA

International Classification:

G06F 17/30

US Classification:

707706, 707749

Abstract:

Systems, methods, and computer readable storage mediums are provided to automatically identifying a classified website. A website is determined to be a candidate site based on a set of heuristics. From among pages constituting the candidate site one or more pages are determined to be listing page candidates and one or more pages are determined to be detail page candidates. Then a listing page score is determined using a listing page classifier. Similarly, a detail page score is determined using a detail page classifier. The listing page and detail page scores each indicate the likelihood that the pages are part of a classified website. A candidate site score is determined based in part on a combination of the listing page score and the detail page scores. Then when the candidate site score is above a threshold the candidate site is determined to be a classified website.

Inventors:

Cheng Xu - San Jose CA, US
Qiying Lin - Guangzhou, CN
Xin Li - Beijing, CN

International Classification:

G06F 17/30

US Classification:

707710, 707E17108

Abstract:

Methods, systems and computer-readable storage medium for determining a crawling schedule. In an aspect, a method includes obtaining crawl history data for a Web site having Web pages, determining a status of the Web pages, determining a total quantity of Web pages that have a status of deleted, calculating a probability that another Web page of the Web site will be removed based on the total quantity, and storing data associating the calculated probability with the Web site. The method can further include determining, for a plurality of sets of the previous time periods, a respective crawl penalty as a combination of a penalty for crawling the Web site and a penalty for showing a deleted Web page based on the calculated probability, and determining a re-crawl schedule based on the crawl penalties.

International Classification:

G06Q 20/32
G06F 3/14
G07F 19/00

Abstract:

Exemplary embodiments may enable synchronization of a display of a mobile computing device with a display of an ATM. The displays first may be synched when a user positions the mobile computing device in proximity to the ATM. Near field communication (NFC) initially may be used when the mobile phone is in proximity with the ATM. Once the communication connection has been realized, the displays may be synchronized to reflect the connection.After the NFC connection has been realized, a cellular connection between a user's mobile computing device with a server having a secure connection with the ATM may be established. One or more financial transactions may be initiated with the ATM from the mobile computing device via the cellular connection. The display of the mobile computing device and the ATM may remain synched during the one or more financial transactions.

International Classification:

H04W 4/00
H04B 17/318
H04W 4/02

Abstract:

Disclosed are systems and methods for improving interactions with and between computers in a communication system supported by or configured with personal computing devices, servers and/or platforms. The systems interact to identify and retrieve data across computers and platforms, which can be used to improve the quality of data used in processing interactions between or among processors in such systems. The disclosed systems and methods perform spatial sensing in order to locate adjacent devices via asymmetric Bluetooth Low Energy (BLE) received signal strength indication (RSSI) distributions. Such spatial location between adjacent devices enables the devices to communicate, share, generate and/or consume digital information as a single, connected and/or localized logical unit.

International Classification:

G06K 9/00
G06F 3/041
G06F 21/32
G06F 3/044

Abstract:

Techniques for communicating particular information from a user to a touch screen device by way of a touch event is provided. Sensors that are operatively coupled to a sensing device sense an input from the user which conveys particular information. This input is then converted by the sensing device into another signal called the sensing device signal which is then transmitted from the sensing device to the user's skin. Then a second set of sensors that are operatively coupled to a touch device receive a user-touch signal that is transmitted from the user's body. The user-touch signal is based, at least in part on the sensing device signal. The touch device then decodes the user-touch signal to determine the location of the touch event on the touch device and sensing device signal embedded in the user-touch signal to extract the particular information related to the user.
