  • Publication number: 20240136531
    Abstract: A conductive composite material, a method of preparing the same, and a secondary battery including the same. The conductive composite material may increase the proportion of an active material when forming an electrode by chemically bonding a conductive material and a binder to each other. A method of preparing the conductive composite material comprises ionizing carbon-based particles in a predetermined polarity, ionizing PTFE particles in a polarity different from that of the carbon-based particles, and chemically bonding the ionized carbon-based particles and the ionized PTFE particles, which are ionized in different polarities, to each other.

  • Patent number: 9966069
    Abstract: Disclosed are a method for processing a dialog based on processing instructing expression in a multi-modal environment and an apparatus therefor. The method for processing a dialog in an information processing device capable of processing digital signals includes the steps of: extracting an instructing expression from an inputted sentence; generating an intermediate instructing expression representing the modifying relations between the words constituting the extracted instructing expression; and searching the object corresponding with the intermediate instructing expression in a predetermined object search range. Thus, a terminal can be effectively and conveniently used without separately clarifying various instructing expressions representing things or objects with the terminal.

  • Patent number: 9641872
    Abstract: A network TV includes a network interface, a user interface, and a controller. The network interface establishes a connection with at least one content provider server through a network. The user interface receives an input signal selecting an icon for display. The controller controls output of the selected icon for display along with an image corresponding to the selected icon. The selected icon corresponds to the content provider and is displayed with one or more other icons that correspond to additional content providers, and the image is based on information received through the network interface from the content provider. Further, a method is disclosed for displaying a real-time broadcast screen and icons for receiving contents at the same time, and easily switching between the real-time broadcast screen and a content providing screen in response to user input.

  • Patent number: 9318102
    Abstract: Disclosed are a speech recognition error correction method and an apparatus thereof. The speech recognition error correction method includes determining a likelihood that a speech recognition result is erroneous, and if the likelihood that the speech recognition result is erroneous is higher than a predetermined standard, generating a parallel corpus according to whether the speech recognition result matches the correct answer corpus, generating a speech recognition model based on the parallel corpus, and correcting an erroneous speech recognition result based on the speech recognition model and the language model. Accordingly, speech recognition errors are corrected.

  • Publication number: 20140317127
    Abstract: Provided are a method and an apparatus for constructing an ontology for a dialogue system. The method for constructing an ontology for a dialogue system includes: generating a domain ontology plane based on intra-plane relation information of a domain defining a relationship between a plurality of domain nodes; generating a main act ontology plane based on intra-plane relation information of a main act defining a relationship between a plurality of main act nodes; and generating an entity name ontology plane based on intra-plane relation information of an entity name defining a relationship between a plurality of entity name nodes. Therefore, it is possible to construct multiple ontology planes and discriminate components of dialogue frames such as a domain, a main act and an entity name. Also, an effective system response can be performed by discriminating dialogue frames exactly using the multi ontology planes.
