Information processing apparatus and method using a conceptual database

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to information processing utilizing a conceptual database.

[0003] 2. Description of the Related Art

[0004] Conventionally, for example, in automatic translation using translation software, translation processing is performed by replacing words according to matching at a surface-layer level (in units of a word).

[0005] However, in translation processing by replacement of words, it is difficult to provide a meaning corresponding to actual contents, resulting in translation in which the context and the object of a sentence cannot be correctly understood.

[0006] In addition, in the form of a database of correspondence between arbitrary two languages, it is necessary to provide a dictionary for each language, and to provide databases whose number equals the number of languages.

[0007] Conventionally, data is retrieved from a database according to matching with specific data. However, this approach is unsuitable for data retrieval from a conceptual database having various data in a complex state.

SUMMARY OF THE INVENTION

[0008] It is an object of the present invention to provide an information processing apparatus and method in which data of a conceptual database can be efficiently retrieved.

[0009] According to one aspect, the present invention which achieves the above-described object relates to an information processing apparatus including input means for inputting information, a conceptual database storing information to be input from the input means and information necessary for forming information relating to a conceptual instance, in a correlated state, and retrieval means for retrieving the conceptual database based on information input from the input means.

[0010] According to another aspect, the present invention which achieves the above-described object relates to an information processing method including an input step of inputting information, and a retrieval step of retrieving a conceptual database storing information to be input and information necessary for forming information relating to a conceptual instance, in a correlated state, based on information input from the input step.

[0011] According to still another aspect, the present invention which achieves the above-described object relates to a computer-readable program for controlling a computer to perform information processing. The program includes codes for causing the computer to perform an input step of inputting information, and a retrieval step of retrieving a conceptual database storing information to be input and information necessary for forming information relating to a conceptual instance, in a correlated state, based on the information input in the input step.

[0012] Other objectives and advantages besides those discussed above shall be apparent to those skilled in the art from the description of a preferred embodiment of the invention which follows. In the description, reference is made to accompanying drawings, which form a part thereof, and which illustrate an example of the invention. Such an example, however, is not exhaustive of the various embodiments of the invention, and therefore reference is made to the claims which follow the description for determining the scope of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0066] A preferred embodiment of the present invention will now be described in detail with reference to the drawings.

[0067]
FIG. 1 is a block diagram illustrating the configuration of hardware of an information processing apparatus according to the embodiment.

[0068] In FIG. 1, an input unit 101 inputs information using a natural language or the like. The input unit 101 may, for example, comprise a keyboard for inputting characters using keys, a speech recognition device for inputting and recognizing a speech, a character recognition device for optically reading and recognizing characters from a document, an on-line/off-line hand-written-character recognition device, or a receiver for receiving information from another system, such as a device for receiving a result of recognition from a character recognition system, or may input information generated by another processing within the same apparatus. Alternatively, at least two of the above-described devices may be provided and selectively utilized.

[0069] A CPU (central processing unit) 102 performs calculation, logical determination or the like for each processing, and controls respective components connected to a bus 106.

[0070] An output unit 103 outputs information. The output unit 103 outputs data obtained from a database, and may, for example, comprise a speech synthesis device for synthesizing and outputting a speech from character information, a display device, such as a CRT (cathode-ray tube), a liquid-crystal display or the like, for displaying character information using character patterns, a printer for printing characters on a document, or a transmitter for transmitting information to another apparatus, such as a database. Output from the output unit 103 may be input to another processing unit within the same apparatus, such as a concept analysis unit or the like. Alternatively, at least two of the above-described devices may be provided and selectively utilized.

[0071] A program memory 104 stores programs for performing controls by the CPU 2 including processing procedures to be described later with reference to flowcharts. The program memory 104 may comprise a ROM (read-only memory), or a RAM (random access memory) where programs are to be loaded from an external storage device or the like.

[0072] A data memory 105 stores data generated in various types of processing, as well as knowledge of a knowledge base (to be described later). The data memory 105 may, for example, comprise a RAM. It is assumed that knowledge of a knowledge base is loaded from a nonvolatile external storage medium before starting processing, or is referred to whenever necessary.

[0073] The bus 106 transfers each address signal indicating a component to be controlled by the CPU 102, each control signal for controlling a corresponding component, and data exchanged between components.

[0074]
FIG. 2 illustrates the relationship between a database and various data utilized by the information processing apparatus.

[0075] A database (DB) 200 includes field variables 201, and stores field data corresponding to each field of the database 200.

[0076] The information processing apparatus includes UI internal variables 203, DB access internal variables 202, and conceptual instance formation internal variables 204, and utilizes data of the database 200.

[0077] The UI internal variables 203 correspond to respective input/output windows of an operation picture frame constituting a user interface (Ul). A UI internal variable 203 stores input information, and is transmitted to a DB access internal variable 202 in accordance with an instruction on the operation picture frame. The UI internal variable 203 also refers to the DB access internal variable 202, is utilized in display processing 205 (to be described later), and displays output information.

[0078] The DB access internal variable 202 refers to a field variable 201, and is utilized in retrieval processing 206 (to be described later). The DB access internal variable 202 also transmits input information to the field variable 201 in accordance with an instruction on the operation picture frame by referring to the UI internal variable 203.

[0079] A conceptual instance generation internal variable 204 receives field data necessary for forming a conceptual instance from the DB access internal variable 202, and is utilized in conceptual instance generation processing 208.

[0080]
FIG. 3 is a flowchart of main window processing illustrating the flow of the entire processing of the information processing apparatus of the embodiment.

[0081] When the information processing apparatus has been started, then, in step S301, each data is initialized by initializing processing for accessing a database (to be described later with reference to FIG. 4). Then, by processing for displaying an operation picture frame performed in step S302, an operation picture frame shown in FIG. 6 is displayed. FIG. 6 is a diagram illustrating the configuration of a user interface on the operation picture frame.

[0082] If the operator performs a certain operation on the operation picture frame, then, in step S303, the type of the operation is determined, and processing corresponding to the determined type is executed.

[0083] When a Search button 602 has been depressed on the operation picture frame shown in FIG. 6, it is determined that retrieval processing has been selected in step S303. Hence, retrieval processing in step S304 is selected, and retrieval processing to be described later with reference to FIG. 7 is started and executed.

[0084] When an Edit button 603 has been depressed on the operation picture frame shown in FIG. 6, it is determined that editing processing has been selected in step S303. Hence, editing processing in step S305 is selected, and editing processing to be described later with reference to FIG. 8 is started and executed.

[0085] When an Add New button 604 has been depressed on the operation picture frame shown in FIG. 6, it is determined that addition processing has been selected in step S303. Hence, addition processing in step S306 is selected, and addition processing to be described later with reference to FIG. 9 is started and executed.

[0086] When a Delete button 605 has been depressed on the operation picture frame shown in FIG. 6, it is determined that deletion processing has been selected in step S303. Hence, deletion processing in step S307 is selected, and deletion processing to be described later with reference to FIG. 10 is started and executed.

[0087] When a Cancel button 606 has been depressed on the operation picture frame shown in FIG. 6, it is determined that cancel processing has been selected in step S303. Hence, cancel processing in step S308 is selected, and input is cancelled.

[0088] When an escape key has been input during display of the operation picture frame shown in FIG. 6, it is determined that end processing has been selected in step S303. Hence, end processing in step S309 is selected, and the operation of the information processing apparatus is terminated.

[0089]
FIG. 4 is a flowchart illustrating the procedure of initialization processing for accessing the database in the main window processing shown in FIG. 3.

[0090] When the initialization processing for accessing the database has been started, then, in step S401, a field variable is assigned in order to select field data to be utilized in the database. Then, the process proceeds to step S402, where a database file to be utilized is selected. Then, in step S403, a default table for retrieval is assigned. Then, in step S404, the above-described field variable is allocated to an internal variable for accessing the database, and the initialization processing is terminated.

[0091]
FIG. 5 is a flowchart illustrating the procedure of processing for displaying the operation picture frame performed in step S302 in the main window processing shown in FIG. 3.

[0092] When the processing for displaying the operation picture frame is started, the process proceeds to step S501, where a DB access internal variable for referring to a field variable of the database is substituted for a UI internal variable, and data of the database is displayed on the operation picture frame.

[0093]
FIG. 7 is a flowchart illustrating the procedure of the retrieval processing performed in step S304 in the main window processing shown in FIG. 3.

[0094] Upon start of the retrieval processing, the process proceeds to step S701, where an input character string is substituted for a SQL (structured query language) sentence to form a SQL sentence for retrieval. Then, in step S702, a retrieval table corresponding to the formed SQL sentenced is selected. Then, in step S703, input information is retrieved. Then, in step S704, it is determined if retrieval has succeeded. If the result of the determination in step S704 is affirmative, the process proceeds to step S705, where processing for acquiring the result of retrieval (to be described later with reference to FIG. 33) is started and executed.

[0095] Then, in step S706, the type of the result of retrieval is determined. If the result of retrieval is surface-layer information, the process proceeds to step S707, where processing for forming a conceptual instance (to be described later with reference to FIG. 39) is started. Then, in step S708, processing for displaying the conceptual instance (to be described later with reference to FIG. 40) is started. Then, the process is terminated.

[0096] If the result of retrieval determined in step S706 is conceptual information, the process proceeds to step S709, where processing for generating the output character string (to be described with reference to FIG. 43) is started. Then, in step S710, processing for displaying an output character string (to be described later with reference to FIG. 44) is started. Then, the process is terminated.

[0097]
FIG. 8 is a flowchart illustrating the procedure of the editing processing performed in step S305 in the main window processing shown in FIG. 3.

[0098] Upon start of the editing processing, the process proceeds to step S801, where a DB access internal variable is acquired. Then, in step S802, it is determined if the DB access interval variable coincides with the UI internal variable. If the result of the determination in step S802 is negative, the process proceeds to step S803, where the UI internal variable is substituted for the DB access internal variable. Then, in step S804, updating processing (to be described later with reference to FIG. 11) is started. Then, the process is terminated.

[0099]
FIG. 9 is a flowchart illustrating the procedure of addition processing performed in step S306 in the main window processing shown in FIG. 3.

[0100] Upon start of the addition processing, the process proceeds to step S901, where a DB access internal variable is acquired. Then, in step S902, it is determined if the DB access internal variable coincides with the UI internal variable. If the result of the determination in step S902 is negative, the process proceeds to step S903, where a new DB access internal variable is added. Then, in step S904, the UI internal variable is substituted for the DB access internal variable. Then, in step S905, updating processing shown in FIG. 11 is started. Then, the process is terminated.

[0101]
FIG. 10 is a flowchart illustrating the procedure of deletion processing performed in step S307 in the main window processing shown in FIG. 3.

[0102] Upon start of the deletion processing, the process proceeds to step S1001, where a DB access internal variable is acquired. Then, in step S1002, it is determined if the DB access internal variable coincides with the UI internal variable. If the result of the determination in step S1002 is affirmative, the process proceeds to step S1003, where the DB access internal variable is initialized. Then, in step S1004, the updating processing shown in FIG. 11 is started. Then, the process is terminated.

[0103]
FIG. 11 is a flowchart illustrating the procedure of the updating processing in step S804 in the editing processing shown in FIG. 8, in step S905 in the addition processing shown in FIG. 9, or in step S1004 in the deletion processing shown in FIG. 10.

[0104] Upon start of the updating processing, the process proceeds to step S1101, where the DB access internal variable is substituted for the field variable.

[0105] Next, a description will be provided of a conceptual database utilized by the information processing apparatus used in this embodiment, with reference to the drawings.

[0106]
FIG. 12 is a diagram illustrating the relationship between concepts of a database and a knowledge base. As shown in FIG. 12, information relating to the concepts is stored in a database 1201. A group of small concept units referring to a knowledge base 1204, i.e., a set of respective concept data 1202, is conceptual information=a Concept 1203.

[0107]
FIG. 13 is a diagram illustrating a configuration of a knowledge base to be referred to by the Concept shown in FIG. 12.

[0108] A knowledge base 1303 to be referred to by a Concept 1302 acquired from input information 1301 includes Slots 1304. Each of the Slots includes a Concept connected by a Function 1305 representing processing to be executed.

[0109] For example, when input information 1301 is a character string ‘Send Mike Mail’, the Concept 1302 refers to the knowledge base 1303, and prepares conceptual information corresponding to the input information 1301. The conceptual information includes surface-layer information, serving as a symbol for representing the conceptual information. In this case, surface-layer information for the Concept 1302 is ‘Send Mike Mail’.

[0110]
FIG. 14 shows specific examples of the effects of translation according to conceptual interpretation, in the case of translation between English and Japanese.

[0111] In translation using conventional software, words are replaced according to matching at the surface-layer level, and therefore actual meaning is not always precisely transmitted.

[0112] For example, the contents of a sentence as shown in Example 1 are precisely translated. However, when the pattern of the sentence changes as shown in Example 2, the meaning of the sentence changes depending on interpretation. In Example 2, by using conceptual interpretation, translation having the correct meaning can be provided. By thus interpreting information with a concept, the correct meaning can be transmitted.

[0113]
FIG. 15 is a diagram illustrating the capability of handling sets of information represented by different media with a single concept. A language 1502, an audio 1503, a character 1504, an image 1505 and a gesture 1506 are handled with a concept 1501.

[0114]
FIG. 16 is a diagram illustrating the structure of each table possessed by a database utilized by the information processing apparatus.

[0115] A retrieval table 1601 is formed based on data of a connection table 1602 and data of each data table 1603. The retrieval table 1601 is retrieved based on input information or information relating to a conceptual instance. The ID of a connection table 1602 corresponding to necessary information is acquired from the retrieval table 1601. It is possible to efficiently acquire information by using the retrieval table 1601.

[0116] If it is allowed to sacrifice efficiency, the retrieval table 1601 may be omitted.

[0117]

[0182]
FIG. 46 is a diagram illustrating an instance retrieval table 1 (by Surface) utilized when a character string is input, from among retrieval tables utilized in step S702 in the retrieval processing shown in FIG. 7.

[0183] When input information is a character string, an instance retrieval table 1 (by Surface) 4601 is started by using a Surface field as a retrieval key. By referring to a connection table 4602 from the result of retrieval, information 4603 necessary for forming a conceptual instance is transmitted.

[0184]
FIG. 47 is a diagram illustrating the structure of the instance retrieval table 1 (by Surface) shown in FIG. 46.

[0185] An instance retrieval table 1 (by Surface) 4701 refers to a connection table 4702, and includes ConnectID data, each having a pointer to a connection table ID, and Surface data, as field data.

[0186]
FIG. 48 is a diagram illustrating retrieval processing when not using the instance retrieval table 1 (by Surface) and when using the instance retrieval table 1 (by Surface).

[0187] 1. When Not Using the Instance Retrieval Table 1 (by Surface)

[0188] A SurfaceRule table 4802 is referred to from a SurfaceRule table ID of a connection table 4801, and Surface field data of the SufaceRule table is sequentially collated with the input character string. In this case, since Surface field data of the SurfaceRule table is referred to from SurfaceRule data in the order of the connection table ID, a considerable amount of time is required for processing, and therefore efficient retrieval cannot be performed.

[0189] 2. When Using the Instance Retrieval Table 1 (by Surface)

[0190] An input character string is retrieved from Surface field data of an instance retrieval table 1 (by Surface) 4803.

[0191] In this case, retrieval is performed from A to Z, i.e., a character string is retrieved by sequentially performing filtering starting from the first character of the character string.

[0192] For example, when a first character ‘p’ has been acquired, retrieval is jumped to the head of a character string starting from p in the Surface field, and the range of retrieval is specified from that position to a character string starting from q. The same processing is performed for the second and succeeding characters.

[0193] By thus limiting the range of retrieval, the processing speed of retrieval increases. In addition, since the amount of data is small because of the structure of the instance retrieval table, the speed of execution of processing increases.

[0194]
FIG. 49 is a diagram illustrating an instance retrieval table 2 (by Concept) utilized when conceptual information is input, from among retrieval tables utilized in step S702 in the retrieval processing shown in FIG. 7.

[0195] When input information is a concept, an instance retrieval table 2 (by Concept) 4901 is started by using a Concept field as a retrieval key. By referring to a connection table 4902 from the result of retrieval, information 4903 necessary for generating an output character string is transmitted.

[0196]
FIG. 50 is a diagram illustrating the structure of the instance retrieval table 2 (by Concept) shown in FIG. 49.

[0197] An instance retrieval table 2 (by Concept) 5001 refers to a connection table 5002 from a ConnectID field, and acquires Concept field data of the connection table 5002 as Concept field data of the instance retrieval table 2.

[0198] The instance retrieval table 2 (by Concept) 5001 refers to the connection table 5002, and includes ConnectID data, each having a pointer to a connection table ID, and Concept data, as field data.

[0199]
FIG. 50 is a diagram illustrating retrieval processing when not using the instance retrieval table 2 (by Concept) and when using the instance retrieval table 2 (by Concept).

[0200] 1. When Not Using the Instance Retrieval Table 2 (by Concept)

[0201] A ConceptRule table 5102 is referred to from a ConceptRule table ID of a connection table 5101, and ConceptRule field data of the ConceptRule table 5102 is sequentially collated with the input concept.

[0202] In this case, since Concept field data of the ConceptRule table is referred to from ConceptRule data in the order of the connection table ID, a considerable amount of time is required for processing, and therefore efficient retrieval cannot be performed.

[0203] 2. When Using the Instance Retrieval Table 2 (by Concept)

[0204] An input concept is retrieved from Concept field data of an instance retrieval table 1 (by Concept) 5103.

[0205] In this case, retrieval is performed from A to Z, i.e., a character string is retrieved by sequentially performing filtering starting from the first character of the character string.

[0206] By thus limiting the range of retrieval, the processing speed of retrieval increases. In addition, since the amount of data is small because of the structure of the instance retrieval table, the speed of execution of processing increases.

[0207]
FIG. 52 is a diagram illustrating a connection table.

[0208] A connection table 5203 connects surface-layer information to conceptual information. Each element of the table is information corresponding to an actually existing instance. That is, an instance is configured by surface-layer information and conceptual information.

[0209]
FIG. 53 is a diagram illustrating a SurfaceRule table, a BodyString table, and a TailString table.

[0210] In another approach, input/output according to any method of representation, such as a sound, an image, a gesture or the like, other than language information mainly using text information can be processed by adding a table for each data type, and forming and utilizing a conceptual instance.

[0211] According to the above-described embodiment, by providing a database dictionary with a function of processing a natural language according to concept dependency, and forming a conceptual instance from an input character string, or by forming an output character string from a conceptual instance, it is possible to understand and precisely transmit a meaning which is closer to an original meaning.

[0212] By generating a retrieval table corresponding to input information for database having conceptual information, it is possible to specify the range of data required for retrieval, and realize efficient retrieval processing to a conceptual database. At that time, by reducing the amount of data by limiting the structure of the retrieval table to specific data, the processing speed of retrieval is further increased. Furthermore, a common knowledge base can be utilized in formation of a conceptual instance and formation of an output character string.

[0213] According to the above-described embodiment, it is possible to understand input information and generate output information without being limited to specific languages.

[0214] It is also possible to perform input/output processing according to a representation form in all domains without limiting the domain to representation of a language.

[0215] The present invention may be applied to a system comprising a plurality of apparatuses (for example, the main body of a computer, an interface apparatus, a display and the like), or to an apparatus comprising a single unit, within a range in which the functions of the above-described embodiment can be realized.

[0216] The present invention may also be applied to a case in which, in order to operate respective devices so as to realize the functions of the above-described embodiment, a computer within an apparatus or a system connected to the respective devices is supplied with program codes of software for realizing the functions of the embodiment, and the respective devices are operated by the computer (or a CPU or an MPU (microprocessor unit)) of the system or the apparatus in accordance with the supplied program. In such a case, the program codes themselves read from a storage medium realize the functions of the above-described embodiment, so that means for supplying the computer with program codes, for example, a storage medium storing the program codes, constitutes the present invention.

[0217] For example, a floppy disk, a hard disk, an optical disk, a magnetooptical disk, a CD(compact disc)-ROM, a CD-R (recordable), a magnetic tape, a nonvolatile memory card, a ROM or the like may be used as the storage medium for supplying the program codes.

[0218] The above-described program codes may, of course, be included within the scope of the present invention not only when the functions of the above-described embodiment are realized by executing the program codes read by a computer, but also when the functions of the above-described embodiment are realized by an OS (operating system) operating in a computer or in cooperation with another software, according to instructions of the program codes.

[0219] The present invention may, of course, be applied to a case in which, after writing program codes read from a storage medium into a memory provided in a function expanding board inserted into a computer or in a function expanding unit connected to the computer, a CPU or the like provided in the function expanding board or the function expanding unit performs a part or the entirety of actual processing, and the functions of the above-described embodiment are realized by the processing.

[0220] When applying the present invention to the above-described storage medium, program codes corresponding to the above-described flowcharts may be stored in the storage medium.

[0221] The individual components designated by blocks in the drawings are all well known in the information processing apparatus and method arts and their specific construction and operation are not critical to the operation or the best mode for carrying out the invention.

[0222] Although the present invention has been described in its preferred form with a certain degree of particularity, many apparently widely different embodiments of the invention can be made without departing from the spirit and the scope thereof. It is to be understood that the invention is not limited to the specific embodiments thereof except as defined in the appended claims.
