Abstract: Disclosed are a system and a method for address translation for a flash memory device, and particularly, disclosed is a technology that is capable of efficiently performing address translation between a logical address provided to the outside of a flash memory and a physical address of an actual flash memory in managing the flash memory device. The system includes: a flash memory system writing a corresponding data page by allocating a physical address space when there is a request for writing a data page from storage clients, and performing address translation between a physical address and a logical address; and a logical address space formed between the flash memory system and the storage client to provide the logical address.

Abstract: Disclosed is a technology for data storage management in a database system, and more particularly, a data storage technology for a mixed OLAP/OLTP workload. A column group selection apparatus for efficiently storing data in a mixed workload processing environment includes a query processor configured to create column access information about queries that are input, a page monitoring module configured to create page-specific query pattern information using information about a page at which each of the input queries accesses and the column access information, a page layout manager configured to create page column group information in which a column group to be used to form each page is selected by applying a tree-based algorithm for selecting a column group to the page-specific query pattern information, and a data storage manager configured to create and store pages in units of column groups based on the page column group information.

Abstract: Disclosed is an apparatus for in-memory data management includes a hybrid memory including a plurality of types of memories with different characteristics and a storage engine. The storage engine rearranges data among the plurality of memories by the unit of a page by monitoring workloads for data stored in the memories and reconfigures a page layout by the unit of the page based on a data access characteristic of an application for each of pages constituting each of the plurality of memories.

Abstract: An apparatus of managing data according to the present invention includes a query processor, a page monitor, a page layout manager and a data storage manager. The query processor processes a user query. At the time of processing the user query, the page monitor collects accessed column information and selectivity information of accessed columns from the query processor and collects access page information from a data storage manager to create page monitoring information. The page layout manager creates page column group information by grouping columns adjacent to each other for each page at a predetermined time interval based on the page monitoring information. The data storage manager stores data in a main memory by reconfiguring a page based on the page column group information for a candidate page of which an access frequency is greater than a predetermined access frequency based on the page monitoring information.

Abstract: Disclosed herein are an apparatus and method for providing an application for processing big data. The apparatus includes a setting unit, a unified information access unit, a metadata management unit, and a database unit. The setting unit sets data collection and analytic levels and a result screen for each of a plurality of tenants. The unified information access unit collects data based on the settings of the setting unit, and analyzes the collected data. The metadata management unit manages metadata about the data collected based on the settings of the setting unit. The database unit stores the collected data and the analyzed data.

Abstract: An SaaS platform for providing an SaaS (Software as a Service) service in cloud computing and a method for provisioning a service for supporting multi-tenants using the platform are provided. The SaaS platform includes a setting environment module configured to set an environment so that setting information for each tenant is converted into metadata to be stored, a metadata manager configured to manage the metadata for each tenant and application data, and an execution engine module configured, if a service request is received from a tenant user, to request the metadata of the corresponding tenant from the metadata manager, to load the metadata of the corresponding tenant transferred from the metadata manager, and to dynamically generate and provide a service to the tenant user.

Abstract: Disclosed herein is an apparatus and method for setting up multi-tenant. SaaS applications, which convert setup information for SaaS applications into metadata, manage the metadata, and dynamically generate and provide a relevant service based on the metadata at the request of a user. The apparatus for setting up multi-tenant SaaS applications includes an environment setup unit for receiving setup information required to set up service environments of SaaS applications and converting the setup information into metadata. A setup information management unit manages setup information for SaaS applications for respective tenants using the metadata converted by the environment setup unit. A service provision unit provides SaaS applications that have been set up in different environments for the respective tenants using the metadata managed by the setup information management unit.

Abstract: A spoken dialog system comprises a speech recognition unit for recognizing a user's input speech to generate a character sequence corresponding thereto; a sentence contents database for storing therein a plurality of sentence contents; a knowledge search unit for searching through the sentence contents to find a match for the character sequence, in the sentence contents database; a dialog model unit for delivering the character sequence to the knowledge search unit to receive the sentence contents therefrom, and setting a dialog model by using the sentence contents; a system response unit for generating an output sentence which harmonizes with the user's input speech or expresses a situation of the system; and a speech synthesis unit for converting the output sentence into the output speech.

Abstract: Provided is a voice dialogue interface field that is related to a speech act-based voice Extensible Markup Language (VoiceXML) dialogue apparatus for controlling a dialogue flow and a method thereof. The speech act-based VoiceXML dialogue apparatus includes a dialogue manager for performing dialogue management by extracting speech act information from a speaker's speech; and a VoiceXML interpreter for performing a dialogue control by determining response speech act information based on the speech act information and an associated speech act-based VoiceXML document.
