Embodiments of the invention enable users with communication devices to access affiliate profiles and perform matches on profiles aggregated from multiple independent computer systems regardless of communications device type or operating system and regardless of affiliate match server computer type, operating system or language. Affiliate profiles may comprise user profiles, advertisement profiles or coupon profiles. In addition, embodiments of the invention allow users to broadcast their location with their permission and join groups based on location parameters and connect to or dial other users by alias without knowledge of a machine address or phone number. Embodiments of the invention utilize information from each user in the form of a profile containing metadata. Examples of the type of metadata that comprises a profile include various categories of information describing a user, group, advertisement or coupon. In addition, the profile may comprise the user's groups and the user's preferences including filters for calculating matches with other user, group, advertisement and coupon profiles. Profiles are typically stored on a community engine server, but may also reside in distributed components configured to interface with the community engine server. A user profile may comprise a flag and other fields for example that signify that a user is interested in receiving advertisements for cars and for the type of car that the user is interested in. When a car dealership accepts delivery of a particular model that the user is interested in, the community engine server finds that affiliate profiles comprising aggregated car dealership advertisements include the same car type that the user is interested in and forward the matching advertisement profile to the user. The user may be paid for the advertisement in cash or coupons for accepting the advertisement. A user profile may also comprise a coupon flag and for example when a store that is an affiliate member provides coupon profiles to the community server engine a user may obtain desired coupons that match the user's profile settings if the user's profile is set to accept coupons. A user may match advertisements and coupons based on a location parameter and may transfer or trade advertisements and coupons with other users. The communication device may be capable of displaying a bar code in it's graphical interface while at a store so as to eliminate the need to physically present coupons.

The invention discloses a client origin information associative perception based metadata pre-acquisition method and system. The method comprises: collecting origin information log records in a kernel space of a client, and transmitting the records to a user space from the kernel space; selecting part of the collected origin information log records at the client as associative training data of metadata, and computing an associative score between every two metadata to obtain an original strong associative list; when the client initiates a file access request and metadata of a file are not in a local metadata cache of the client, pre-acquiring multiple strongly associative metadata from the strong associative list of the client, downloading corresponding metadata from a metadata server, and updating the local metadata cache of the client; and according to added origin information log records, regularly updating the strong associative list of the metadata. According to the method and the system, the metadata cache hit rate of the client is increased, and the frequency of access to the metadata server is reduced, so that the performance of the metadata server is improved.

The embodiment of the present application discloses a data recovery method of a solid-state disk and a solid-state disk, which are used for simultaneously saving and simultaneously recovering metadataof an L2P when the solid-state disk is powered off and powered on, thereby improving the practicability of the solid-state disk. A method for implement an embodiment of that present application includes: a solid state drive converting metadata of a logical-to-physical address translation L2P type into at least two metadata types; setting a static random storage area for each metadata type; calculating the number of LBAs according to the data capacity of the L2P type metadata and the data capacity of the preset logical block address LBA; when the solid-state disk normally runs, the solid-statedisk storing the first change amount and the first base data into the flash memory NAND respectively according to the LBA; when the solid-state disk is powered off, the solid-state disk storing the second change amount and the second base data to the NAND according to the LBA; when the solid-state disk is powered on, the solid-state disk reading the base data respectively according to the LBA, and reading the change amount respectively according to the LBA; corresponding base data being patched with changes.

The embodiment of the invention discloses a Metadata reconstruction method, apparatus, and computer-readable storage medium. Each type of metadata has at least one corresponding data block, and the metadata is brushed down to the corresponding data block. Recording the corresponding type identification for the metadata completing the power-down operation, and storing the type identification corresponding to the type identification and the metadata type not performing the power-down operation into the preset storage space; Judging whether the type identification stored in the preset storage space covers all the type identification corresponding to the power-down operation after the system is powered on; If not, the target data blocks corresponding to the type identification not covered arescanned, and the metadata in each target data block is restored to its corresponding storage location. The required metadata can be obtained only by scanning the data blocks corresponding to the missing type identifier during power-up, which saves the scanning time of metadata recovery and improves the efficiency of metadata reconstruction.

The invention provides an analysis method and system for house type data, and belongs to the technical field of house information processing. The method comprises the steps of obtaining a house type coordinate set according to house type data with wall size information and window size information, and determining a metadata type of a house type based on the house type coordinate set; determining ascreening condition and a judgment condition according to the metadata type; filtering the house type coordinate set according to the screening condition to obtain a key geometric point coordinate set; and determining metadata of the house type corresponding to the key geometric point coordinate set according to the metadata type determined by the house type coordinate set and the judgment condition. The method and system are used for automatically generating the description data of the house according to the house type data.
