Abstract: Systems and methods for storefront recognition are provided. A surveyor or other user can access an application implemented on a computing device. A source image of a storefront of an entity can be captured by the surveyor using an image capture device (e.g. a digital camera). A feature matching process can be used to compare the source image against a plurality of candidate images of storefronts in the geographic area and return a list of the candidate images with the closest match. Each candidate image returned by the application can be annotated with a similarity score indicative of the similarity of the source image with the candidate image. The surveyor can use the similarity scores and the candidate images to determine whether the store has been previously investigated. The user can interact with the application to indicate whether the entity seeds to be investigated.

Abstract: In a method of error recovery when downloading data files using an application server, the application server connects to at least one terminal device and several file servers. The application server receives a file downloading request from the terminal device, finds a first file server nearest to the terminal device, and downloads the required data file from the first file server to the terminal device. The application server searches a file configuration table to find a second file server which is away from the first file server when the data file has not been successfully downloaded from the first file server, downloads the required data file from the second file server to the terminal device, and synchronizes the data file of the second file server to recovery the data file of the first file server when the data file has been successfully downloaded from the second file server.

Abstract: A computer reads a patent application file from a database connected to the computer, and inserts content of the patent application file into a first file format. The computer converts the content of the patent application file in the first file format using a language converting API, and inserts the converted content from the first file format into a second file format. The computer replaces error words with correct words corresponding to the error words, in response to a determination that the converted content in the second file format comprises error words.

Abstract: Automatic trading of virtual characters in online applications comprises publishing virtual characters by a first user in a trading system that involves verification at an application server and locking of the selected virtual characters at the application server. This can ensure that the trading of virtual characters is true, reliable and prompt, and reduces the loss to users arising from the trading of virtual characters.

Abstract: A server stores a plurality of initial files and parameters of the initial files. When a user inputs contents of the initial files to the server, the server obtains a template for each initial file. The server searches for contents of all columns in each template from the parameters and the input contents. The searched contents are put in the columns of each template. The templates with the put contents are generated to object files corresponding to the initial files.

The last index of a data index list stored in a database of a storage device is established, and an m-digits number is generated according to the storage capacity of the database. The m-digits number of the last index is calculated to obtain a sequence number, and a sequence index of the data file is generated according to the sequence number of the last index and the index information of the data file. The sequence index of the data file is inserted into the last position of the data index list, and the data index list is saved into the database of the storage device.

Abstract: A server generates a first ID in response to a user inputting a username on a web portal provided by the server. If the user selects a link page displayed through the web portal, the server generates a second ID and sends the first ID and the second ID to the selected link page. The server detects if the user can access the selected link page by reference to the first ID and the second ID. If the server verifies the information successfully, the link page may be entered using the portal information.
