    Abstract: PURPOSE: An efficient query processing method and a device thereof are provided to improve search performance by using a partial character string having an unfixed length. CONSTITUTION: A UI(User Interface)(105) receives a query character string and outputs a document including the character string. A database(165) stores information about various documents. A processor(135) generates an effective character string set composed of partial character strings having different lengths through the query character string. The processor determines one of subsets of the effective character string set as a candidate set based on costs of the subsets for accessing the database. The processor searches the database for the document including the query character string by using the candidate set. [Reference numerals] (105) User Interface; (110) Character string set generating unit; (120) Candidate set determining unit; (130) Document searching unit; (140) Index DB; (150) Inverted index DB; (160) Document DB

    Abstract: PURPOSE: A query processing method based on N-gram and an apparatus thereof are provided to improve query processing performance even when the length of a query is long. CONSTITUTION: A query processor(710) selects some N-grams among total N-grams for a query based on a query processing cost and uses a posting list for the some N-grams to extract a candidate set of a document in which a query exists. The query processor determines, based on the candidate set, the document including the query.

    Abstract translation: 目的:提供一种基于N-gram及其装置的查询处理方法,以便即使查询长度较长,也可提高查询处理性能。 构成:查询处理器(710)基于查询处理成本为查询选择总N克中的一些N克,并使用一些N克的发布列表来提取其中查询的文档的候选集 存在。 查询处理器基于候选集确定包括查询的文档。
