摘要： The method and system for retrieving information allow the user to retrieve desired information from database systems by simply specifying retrieval content and retrieval conditions using languages familiar to the user, without having to know the names for the relevant database systems or their structures or without having to interact with the platform of the meta-information, i.e., information concerning the use of database systems and accessing method. The present method allows retrieval of information from different database systems connected to a communication network, by using reference information stored beforehand to access different database systems; consulting the reference information to determine database systems which contains data to satisfy the information retrieval request by converting requested items to equivalent related words that the system can recognize. The storage locations of the data and instructions on how to acquire the data are determined using relational items to link various tables so that an information retrieval statement can be prepared by the system program on user's behalf. The databases are searched according to the acquiring method and the information retrieval content described in the system prepared statement, and the retrieved information is presented for viewing in a format that is used by the information searcher.

摘要： An integrated retrieval scheme retrieves data involved in a plurality of semi-structured documents scattering over open networks and collects the required information item by item from the semi-structured documents through a unified interface without regard to differences in the document structures, presentation styles, and elements of the semi-structured documents. The search scheme receives a query consisting of search items and search conditions from a user. The search scheme finds, according to location data that specifies the location of each of the semi-structured documents, the location of each semi-structured document that contains all search items and converts, if necessary, item presentation styles of the entered query into that of the location found semi-structured documents according to style conversion data, and forms queries for the location found semi-structured documents, and transmits the queries to the found locations and obtains the location found semi-structured documents, and extracts item data from the obtained semi-structured documents according to structure data being used to delimit document into items and attribute data being used for conditional retrieval, and prepares a search result, and converts, if necessary, item presentation styles of the search result into the item presentation styles of each user according to the style conversion data.
