`
`A document processing system for processing docu-
`ments by using structured keywords comprises an out-
`put system and a receiver system. The output system
`includes a first storage for storing a structured keyword
`dictionary containing structured keywords among
`which relations are systematically structured, and link-
`age unit providing linkage information for establishing
`correspondences between constituent parts of an input
`document and corresponding ones of the keywords.
`- The receiver system is coupled to the output system and
`includes a second storage for storing structured key-
`words among which relations are systematically struc-
`tured, and retrieving unit having inputs supplied with
`the document and the linkage information for retrieving
`the document to thereby form data of a predetermined
`edition format by using the structured keyword read
`out from the second storage. Data transfer between the
`output system and the receiver systems can be per-
`formed either on-line or off—line.

`
`INFORMATION PROCESSING SYSTEM AND
`METHOD FOR PROCESSING DOCUMENT BY
`USING STRUCTURED KEYWORDS
`
`BACKGROUND OF THE INVENTION
`. The present invention relates to information process-
`ing method and. system for automatically collecting
`desired information from a large amount of information.
`As an information processing system for acquisition
`of information, there is heretofore known an informa-
`tion retrieval system which is so arranged as to make
`access to a database or a knowledge base in which infor-
`mation has previously been stored or accumulated, as is
`described in IRA-60440443.
`Further, as the methods for retrieval of information,
`there are known a method in which the user designates
`items for retrieval in accordance with items of a table
`constituting a part of a database on the basis of informa-
`tion concerning a data storage structure adopted in the
`database and a method of simplifying designation of the
`items for retrieval by resorting to an associative re-
`trieval and a synonym processing. Besides, there has
`already been proposed a method according to which
`documents added with keywords are stored as they are
`for allowing extraction of document constituent parts
`for which coincidence is found with the keywords and
`a method according to which a stored document is
`retrieved when the keywords available for the retrieval
`coincide with synonyms detected from all the texts of
`that document.
`'
`
`The first mentioned prior art method is however
`disadvantageous in that information other than the pre-
`determined table items Can not be processed because of
`the tabular structure of the database. If the number of
`table items is increased in an effort to cope with the
`above problem, then the structure of the database be-
`comes complicated, involving difficulty in maintenance
`and management thereof.
`‘
`In thecase of the document retrieving methods in
`which keywords are used for retrieval, the requisite
`information as wanted by the user can be obtained only
`when the user having read the extracted document part
`can understand the content thereof. As a consequence,
`when information is to be collected for a specific item
`or matter from many documents, the burden to be borne
`by the user will increase significantly, giving rise to a
`problem.
`
`SUMMARY OF THE INVENTION
`
`It is therefore an object of the present invention to
`provide an information processing system which is ca-
`pable of automatically collecting necessary or de-
`manded information from a large amount of stored
`information.

`
`It is another object of the present invention to pro-
`vide an information processing system which is substan-
`tially immune to the shortcomings of the prior art
`method, such as difficulty in maintenance and manage-
`ment, and the serious burden imposed on the user and
`others upon automatic collection of information.
`A further object of the invention is to provide a data-
`base retrieving method and system capable of collecting
`automatically those data which meet the demand of the
`user by allowing extraction of the content of a docu-
`ment having meaning implied by keywords as desig-
`nated.
`

`
`2
`In view of the above and other objects which will be
`apparent as description proceeds,
`there is provided
`according to an aspect of the present invention an infor-
`mation processing system comprising a combination of
`.a sender system and a receiver system, wherein the
`sender system includes a structured keyword dictionary
`containing keywords among which relations are sys-
`tematically structured, a unit for adding linkage infor-
`mation to constituent parts of a document as inputted
`which bear respective relations to the keywords se‘
`lected from the structured keyword dictionary and a
`unit for sending out retrieval information containing the
`structured keywords, the linkage information and the
`document data added with the linkage information,
`while the receiver system includes a retrieving unit
`responsive to reception of the retrieval information
`from the sender system for retrieving the document
`data by using the linkage information and the structured
`keywords.
`The structured keyword mentioned above may be
`implemented on a knowledge domain basis so as to have
`at least one of the links including a link to a keyword
`representing a higher rank concept, a link to a keyword
`representing a lower rank keyword and a link to a key-
`word representing a synonym, as is illustrated in FIGS.
`2 and 3 of the accompanying drawings.
`Correspondence between the keyword selected from
`the structured keywords and the corresponding constit-
`uent part of the document should be established in light
`of the structure of the structured keywords such that a
`keyword of concern representing an upper rank con-
`cept of the semantic content of a constituent part of the
`document is linked to that document part which thus
`represents the lower rank concept of the keyword of
`concern, as will be elucidated later on by reference to
`FIG. 5.
`
`Further, the retrieving unit for retrieving the docu.
`ment data with the aid of retrieval information and the
`structured keywords may be composed of a functional
`part for designating a keyword needed for the retrieval
`by consulting the structured keyword dictionary, 3
`storage for storing the structured keywords, a retriev-
`ing unit for retrieving document data by using the struc-
`tured keywords stored in the storage and the retrieval
`information, and a second storage for storing the result
`of the retrieval.
`
`In this conjunction, the second storage for storing the
`result of the retrieval may preferably be imparted with
`a function for editing the data resulting from the re-
`trieval
`in accordance with a designated or inputted
`format for editing and storing the result of editing so
`that automatic editing of the document data as retrieved
`can be performed.
`For retrieving the document data with the aid of
`retrieval information and the structured keyword desig-
`nated and stored for the retrieval, the constituent part of
`the document representing the lower rank concept of
`that keyword should preferably be extracted by using
`the linkage information.
`information for re-
`The retrieval information (i.e.
`trieval) may preferably include in addition to at least the
`structured keyword, the linkage information for indi-
`cating correspondence between the structure keyword
`and a corresponding constituent part of the document
`and document data added with the linkage information
`as described above, at least one of information resulting
`from copying or extraction of a constituent part of the
`document corresponding to the structured keyword,

`document part location designating linkage information
`indicating the position or location of that constituent
`part in the document Or identification information for
`identifying an original document to which the docu-
`ment part belongs. In that case, the editing can corre-
`spondingly be simplified while facilitating confirmation
`and correction of the document data to another advan—
`tage.
`information supplied to the
`the retrieval
`Besides,
`receiver system from the sender system may be trans-
`mitted through a communication network, as illustrated
`in FIG. 1.
`,
`,
`Alternatively, the retrieval information to be trans-
`ferred as the output/input information may include at
`least information capable of being written in an informa-
`tion carrying medium and read therefrom, as in the case
`of an embodiment of the invention shown in FIG. 9.
`According to another aspect of the invention, there is
`further proposed for achieving the previously men-
`tioned objects an information processing method,
`wherein a process for establishing correspondences
`between the structured keywords and corresponding
`document data includes an input procedure for allowing
`a user to input a keyword representing subject matter of
`a document, a proCedure for extracting a keyword
`through matching processing of the keywords con-
`tained in a structured keyword dictionary with the
`document data, a linkage forming procedure for form-
`ing a link to a candidate for constituent parts (descrip-
`tion) in the document which corresponds to the key-
`word through syntax analysis (parsing) of the document
`data and a procedure for allowing the user to confirm
`the validity of the formed link or correct the link, as will
`hereinafter be described in detail by reference to FIG. 4.
`According to another aspect of the invention, there is
`provided an information processing method in which a
`process of collecting document data through retrieval
`for editing includes an editing format designating proce-
`dure, a procedure for designating items to be retrieved,
`conditions for the retrieval and the structured keywords
`and a data collecting procedure,
`wherein the editing format designating procedure
`includes a procedure for inputting an editing format and
`items to be retrieved and a procedure for designating
`fields for the conditions and the items for retrieval,
`the procedure for designating the items to be re-
`trieved, the condition for retrieval and the struCtured
`keyword includes a procedure for designating the re-
`trieval condition to be entered in the retrieval condition
`designating field of the editing format and a procedure
`for designating the retrieval items to be entered in the
`retrieval item designating field of the editing format,
`and
`
`the data collecting procedure includes a retrieval
`procedure for performing in response to the input of the
`retrieval information a matching processing between
`the structured keyword of the retrieval information and
`that of the retrieval condition, and a data editing proce-
`dure for editing the document data in accordance with
`the editing format, wherein the data editing procedure
`includes a matching processing procedure for perform-
`ing a matching processing between the structured key-
`word of the item for retrieval and that of the retrieval
`information, a document part extracting procedure for
`extracting a constituent part of document correspond-
`ing to the keyword by using document-keyword link-
`age information (i.e. linkage information for interlinking
`a document part and a keyword) contained in the re-
`
`4
`trieval information, and a storing procedure for storing
`the document part corresponding to the keyword in the
`retrieval item designating field in accordance with the
`editing format.
`The keywords used for the retrieval of information
`according to the present invention are conformed to the
`structured keyword dictionary in which the relations
`between or among the keywords are systematically
`structured on a knowledge-domain basis (i.e. in each
`domain of knowledge), wherein those keywords linked
`together in a standardized semantic relationships, such
`as the relationship among concepts of higher and lower
`ranks, are used in the respective relevant knowledge
`domain. Accordingly, there arises scarce differences of
`individuals in understanding the keywords because the
`semantic relations between the keywords are easy to
`understand distinctiVely.
`In conjunction with establishment of correspon-
`dences between the the constituent parts of a document
`and the structured keyword, it is noted that those con-
`stituent parts of the document which should semianti-
`cally belong to a same keyword may assume various
`meanings. Under the circumstances, it is taught accord-
`ing to the invention to previously establish correspon-
`dences between the keywords selected from the struc-
`tured keyword dictionary and the constituent parts of
`the document by using the linkage information. Conse-
`quently, according to the invention, the user can get rid
`of trouble of handling unnecessarily lots of data for the
`retrieval. Furthermore, difficulty in maintenance and
`management can significantly be mitigated by virtue of
`establishment of correspondences between the key-
`words and the constituent parts of the document as well
`as owing to utilization of the standardized structured
`keyword dictionary as a basis.
`As will be seen from the foregoing, because the link-
`age inforrnation for establishing correspondences be-
`tween the keywords and the constituent parts of a docu-
`ment which semantically correspond to the above key-
`words are added to the constituent parts of a document,
`there can easily be extracted the constituent parts of the
`document, such as words, phrases/clauses and sen-
`tences which semantically correspond to the keywords
`designated by the user for the item for which he or she
`wants to acquire information.
`Additionally, by storing internally of the information
`processing system the keywords designated by the user
`for the item for which information is to be acquired,
`extracting the constituent parts of the document corre-
`sponding semantically to the designated keywords from
`those documents supplied by way of an information
`network or other various media and storing the ex-
`tracted document constituent parts, there can be real-
`ized an automatic data collection.
`By designating the editing format for editing the data
`collected, the data desired by the user can be progres-
`sively and increasingly stored and accumulated. By way
`of example, as the editing format, a table framework
`may be provided, whereon the keywords may be desig-
`nated at locations corresponding to the items of the
`table. When fresh document data are supplied to the
`information processing system according 'to the inven-
`tion,
`the document constituent parts corresponding
`semantically to the individual keywords mentioned
`above can be extracted by using the linkage information
`and then can be written in the table at corresponding
`columns. By repeating this procedure, the table can be
`autonomously and increasingly expanded.

`Finally, by attaching to the extracted document con-
`stituent parts the linkage infOrmation indicating the
`locations in a document from which the constituent
`
`parts have been extracted or by attaching the identifica-
`tion number of the document to which the extracted
`' document constituent parts have belonged, the user can
`straightforwardly read out the relevant parts of the
`document and easily confirm whether or not the corre-
`spondences between the keywords and the document
`parts are correct, whereon an error, if any, can be cor-
`rected.

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`Now, the present invention will be described in detail
`in conjunction with preferred or exemplary embodi-
`ments thereof by reference to the accompanying draw-
`mgs.
`FIG. 1 shows in a functional block diagram a general
`arrangement of a document processing system accord-
`ing to a first embodiment of the invention. In this figure,
`a reference numeral 200 denotes generally an informa-
`tion sender system adapted to generate retrieval infor-
`mation (i.e. information for retrieval) to be transmitted
`through a communication network 500 to an informa-
`tion receiver system which is generally denoted by a
`numeral 201 and arranged to perform processing for
`retrieval and editing by utilizing the retrieval informa-
`tion as supplied. Thus, it can be said that the document
`processing system illustrated in FIG. 1 is implemented
`in the form of a retrieval information transmission/-
`reception system, so to say. In the information sender
`system 200, a reference numeral 1 designates a docu-
`ment data storage, and a numeral 2 denotes a keyword
`dictionary storage. Any given one of the keywords
`contained in the keyword dictionary 2 is so structured
`as to have at least one link, including a link leading to a
`keyword representing an upper rank concept of the
`given keyword, a link to a keyword representing a
`lower rank concept and a link to a keyword having
`

`semantically same meaning (i.e. synonym) as the given
`keyword on the basis of the field or domain of the
`knowledge to which the given keyword belongs (i.e. on
`a knowledge-domain basis), as is illustrated in FIG. 2.
`Thus, the keyword dictionary 2 may be termed as a
`structured keyword dictionary containing keywords
`which are systematically structured by means of inter-
`keyword linkages or relations established as mentioned
`above. This dictionary 2 will hereinafter be termed the
`structured keyword dictionary, while the keywords
`related to one another by the links will be referred to as
`the structured keywords. Turning back to FIG. 1, a
`reference numeral 3 denotes a unit for selecting from
`the structured keyword dictionary 2 the structured
`keywords in the domain to which the subject matter of
`a given document contained in the document data stor-
`age 1 relates, for the purpose of adding to the selected
`document the structured keywords and linkage infor-
`mation which is required for establishing correspon-
`dence between the structured keywords and relevant
`constituent parts of the selected document. A numeral
`31 denotes a user interface for actually establishing the
`correspondences between the structured keywords and
`the constituent parts of the document in accordance
`with the output information of the unit 3. Further, a
`retrieval information storage unit generally denoted by
`10 serves for storing the retrieval information and in-
`cludes a buffer storage 12 for storing the structured
`keywords (also designated by 12) as selected, a buffer 11
`for storing the link-affixed document data (11) added
`with the'information of the linkages between the con-
`stituent parts of the document and the structured key-
`words (hereinafter simply referred to as the document-
`keyword linkage information), and a buffer 13 for stor-
`ing the document-keyword linkage information (13)
`itself. A reference numeral 21 denotes an interface
`
`through which the retrieval information 10 is sent out
`onto the communication network 500.
`In the information receiver system 201 which can be
`connected to the information sender system 200, a refer-
`ence numeral 121 denotes a communication interface
`through which the retrieval
`information described
`above is received, and a numeral 110 denotes a storage
`unit for storing the retrieval information as received.
`This storage unit 110 also includes a buffer 112 for stor-
`ing the structured keywords (also designated by 112), a
`buffer 111 for storing the link-affixed document data
`(111) and a buffer 113 for storing the document-
`keyword linkage information, as in the case of the stor-
`age unit 10 incorporated in the information sender sys-
`tem 200. At least one receiver system connected to the
`sender systems can receive the retrieval information 10
`sent out onto the communication network 500 through
`the communication interface 121, w
