Abstract: An unstructured document analysis method according to an embodiment includes: operations of acquiring unstructured document data including font characteristic data and document structure data, extracting text included in the unstructured document data on the basis of the font characteristic data or the document structure data, classifying the extracted text into a pre-classified item using a trained neural network model, acquiring a content query related to the content included in the unstructured document data and associated with the pre-classified item, and generating an answer to the content query on the basis of the extracted text classified into the item.

Abstract: Disclosed is an electronic device including an antenna including a radiating portion and a feeding portion connected to the radiating portion; a tunable element electrically connected to the radiating portion and configured to influence an electrical length of the radiating portion with respect to a specified frequency; an amplifier electrically connected to the feeding portion and configured to amplify a signal to be transmitted to an external electronic device through the radiating portion; and a control circuit electrically connected with the antenna, the tunable element, and the amplifier. The control circuit is configured to determine strength of a signal reflected from the radiating portion while the signal is transmitted to the external electronic device through the radiating portion; and adjust a value of the tunable element to reduce the strength of the reflected signal.
