20120004840 | SYSTEM AND METHOD FOR COMPUTING NECESSARY TIME FOR TRAVEL BASED ON WAITING TIME - Provided are a system and method for computing a total travel time according to a transportation type, based, in part, on a waiting time to wait for traveling in the transportation. A system for computing a necessary time for travel may include an input unit to receive a starting point and a destination point, and a necessary time computing unit to compute a necessary time taken to travel from the starting point to the destination point, by adding a waiting time and a travel time, thereby minimizing an error in computing the necessary time for travel. | 01-05-2012 |
20120102034 | SYSTEM AND METHOD FOR RECOMMENDING LOCATION-BASED KEYWORD - According to exemplary embodiments of the invention, a location-based keyword recommending system and method are provided. The location-based keyword recommending system may include a keyword collecting unit to store location information regarding a location where a keyword is input, a region setting unit to set a virtual region by performing clustering of the location information with reference to the keyword, a region combining unit to combine virtual regions overlapping each other into one virtual region, and a keyword recommending unit to provide a location-based keyword based on the keyword related to the location information of the virtual region. | 04-26-2012 |
20120284270 | METHOD AND DEVICE TO DETECT SIMILAR DOCUMENTS - A method for detecting similar documents includes extracting an entity from each of a first web document and a second web document; determining an importance contribution element corresponding to each of the web documents; calculating, using the processor, weights for each entity based on the determined importance contribution elements; and determining whether the web documents are similar documents based on the calculated weights. A device to detect similar documents includes a storage device; an entity extractor stored on the storage device and configured to extract an entity from a first web document and a second web document and to determine an importance contribution element from each of the web documents; a weight calculator configured to calculate weights of each entity based on the determined importance contribution elements; and a similar document detection unit configured to determine whether the web documents are similar documents based on the calculated weights. | 11-08-2012 |

20150032759 | SYSTEM AND METHOD FOR ANALYZING RESULT OF CLUSTERING MASSIVE DATA - Disclosed are a system and a method for analyzing a result of clustering massive data. An open-source map/reduce framework named Hadoop is used to calculate a silhouette coefficient corresponding to a significance verification index capable of evaluating a result of clustering massive data. To implement the system and the method for analyzing a result of clustering massive data, clustered data is divided into blocks. For all of the blocks, input splits are generated. Then, the generated input splits are assigned to multiple computers. Each computer stores only data of blocks included in an input split assigned in a memory, and calculates a silhouette coefficient for each record. Each computer provides only the calculated silhouette coefficient to an index coefficient calculation apparatus, and enables the index coefficient calculation apparatus to calculate a silhouette coefficient for a cluster. Therefore, the result of clustering the massive data can be rapidly and objectively analyzed. | 01-29-2015 |

20140298835 | DEODORIZING FILTER AND REFRIGERATOR HAVING THE SAME - A deodorizing filter including at least one deodorizing member to adsorb odor particles contained in fluid. The deodorizing member includes a substrate having plural pass-through pores to allow passage of the fluid, an adherent material applied to a surface of the substrate, and plural porous deodorizer materials fixed to the surface of the substrate by the adherent material to adsorb the odor particles. The deodorizing filter more effectively deodorizes interior air of a refrigerator owing to an increased contact area between interior air of the refrigerator and the deodorizer materials of the deodorizing filter. | 10-09-2014 |
20150059398 | STORAGE CONTAINER AND REFRIGERATOR HAVING THE SAME - A storage container includes an inflow hole and an outflow hole through which cold air flows, and deodorizing filters for removing odorous materials are mounted in the inflow hole and the outflow hole. Therefore, when foods containing odor-causing materials are put in the storage container to be stored in a storage compartment, the odor-causing materials are prevented from spreading inside the storage compartment, thereby fundamentally removing odors from the storage compartment. In addition, the cold air of the storage compartment continuously flows in and out of the storage container through the inflow hole and the outflow hole, and therefore foods stored in the storage container may be kept fresh. | 03-05-2015 |
