SYSTEM AND METHOD FOR EXTRACTING CAPTION CANDIDATE AND SYSTEM AND METHOD FOR EXTRACTING IMAGE CAPTION USING TEXT INFORMATION AND STRUCTURAL INFORMATION OF DOCUMENT

摘要

PURPOSE: A system and a method for extracting caption candidate, and a system and a method for extracting image caption using text information, and structural information of document are provided to improve image caption extracting function by calculating the probability that the image-caption candidate pair is the correct answer pair. CONSTITUTION: A system and a method for extracting caption candidate, and a system and a method for extracting image caption using text information comprises an image-caption candidate pair generating unit, a feature extracting unit, and an image caption selecting unit. The image-caption candidate pair generating unit creates the included in a document image-caption candidate pair about an image using a text and structural information of a document(S801). The feature extracting unit extracts the generated feature about the image-caption candidate pair(S802). The image caption selecting unit selects the image caption from the image-caption candidate pair of which is generated using the probability according to the extracted feature(S803).
