Abstract

<P>PROBLEM TO BE SOLVED: To provide a function to properly determine the hierarchical structure of parentheses or the like even about pieces of information whose correspondence is not necessarily clear for such a reason as the parentheses not having a nested structure. <P>SOLUTION: The information processor having a search means for searching leading and trailing parentheses is provided with a determining means for determining whether or not a leading parenthesis and a trailing parenthesis form a pair. Information about the leading and trailing parentheses determined to form one pair is outputted to an information output means, whereby another information processor is allowed to add process reference information later. Further, areas surrounded by the leading and trailing parentheses determined by the determining means to form pairs may be given different colors when displayed on a screen. Alternatively, only the leading and trailing parentheses determined by the determining means to form pairs may be displayed in different colors. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an information processing apparatus, an information processing method, and a recording medium for processing information including parentheses or tags.

First, in Japanese Patent Laid-Open No. 7-302264, when parentheses are input, display is performed in a display color different from other character codes, and the rear brackets corresponding to the front brackets are unified to the same color, There has been described what provides an information processing apparatus capable of grasping the correspondence between parentheses at a glance.
JP-A-7-302264

However, according to the above technique, it is assumed that there is only one kind of open parenthesis and closing parenthesis in each piece of information, and what is recognized as a closing parenthesis corresponding to a certain open parenthesis is the opening parenthesis. It is limited to the same kind of closing parenthesis as the parenthesis (for example, a normal closing parenthesis for a normal opening parenthesis or a closing bracket for an opening bracket).
Therefore, the above technique cannot cope with a case where a plurality of types of open parentheses or closing parentheses exist. In addition, it is assumed that the same kind of closing parenthesis corresponding to the opening parenthesis has a so-called nested structure. If not, it is not applicable.
Therefore, the present invention is a function that appropriately determines the hierarchical structure of parentheses not only for information in which there is only one kind of open parenthesis and closing parenthesis, but also for information in which the correspondence relationship of parentheses is not necessarily clear as described above. It is an issue to provide.

  The present invention has been made in view of the above problems, and in an information processing apparatus having a search means for searching for a front bracket and a back bracket, whether or not the front bracket and the rear bracket constitute a pair. Discriminating means for discriminating the above is provided. In this case, the parentheses and rear brackets constituting the pair may not be the same kind of rear brackets as the front brackets. Here, the same kind of parenthesis refers to what is usually used as a pair for a specific front bracket.

  In addition, by outputting information about the parentheses and rear brackets that constitute the pair determined by the determination means to the information output means, this is followed by reference information for processing by another information processing apparatus. It becomes possible to do.

  For example, for the information output means, the information originally input from the information input means is immediately before or immediately after the front brackets constituting the pair of pairs determined by the determination means, and immediately before or after the rear brackets. By inserting identification information (for example, a pair of HTML tags is conceivable, but not limited thereto), reference information for later computer processing can be added.

  Furthermore, regarding the areas surrounded by the front brackets and rear brackets that constitute the pair determined by the determination means, the colors can be changed for each area when the areas are displayed on the screen. . In addition, it is possible to display only the front brackets and rear brackets constituting the pair of pairs determined by the determination means by changing them to different colors.

According to the present invention, it is possible to acquire the hierarchical structure of information that has a complicated correspondence relationship between parentheses and whose hierarchical structure is difficult to understand, and information that does not have the same type of parentheses as the preceding parentheses. Thereby, reference information about the hierarchical structure can be added and subsequent processing by the computer can be easily performed. In addition, by expressing the hierarchical structure by changing colors, the hierarchical structure becomes clear even when the user looks at the information.

  An embodiment of the present invention will be described with reference to FIGS. 1, 2, 3, and 4. FIG. Note that the embodiment is not limited to this.

  First, in FIG. 1, the parenthesis type correspondence storage memory 2 stores information on the type of front brackets and the type of rear brackets. Are stored, and a numerical value representing the type of the front brackets or rear brackets.

  Parentheses consist of front brackets and back brackets. Here, the front brackets refer to characters, character strings, or information meaning that a certain range starts, and the rear brackets are specific characters, character strings, or information corresponding to a certain front bracket, Means the end of the range that begins with the brackets. Note that specific examples of parentheses include commonly used parentheses and lock brackets, and tags used in XML and HTML, but are not limited thereto.

  In this example, whether or not it is a front bracket or a back bracket in Table 1 is determined based on whether the numerical value in the type column is negative or positive.

  Since normal brackets in Table 1 may use both full-width and half-width characters, the full-width and half-width are separately stored in the parenthesis correspondence storage memory. In Table 1, No1, 2 and No6, 7 correspond to full-width and half-width brackets, respectively.

  * In Table 1 means that it applies to all characters other than>.

  In FIG. 1, the storage memory for the brackets 3 is the position where the brackets exist (if the brackets consist of multiple characters, the position of the first character or the last character of the brackets) , Or both, and so on) and type.

  In FIG. 1, the parenthesis storage memory 4 indicates the position and type where the front brackets exist and the position where the corresponding rear brackets exist (if it consists of a plurality of characters, the first of the parentheses thereafter. And the last character position or both, the same shall apply hereinafter) and type. In this case, the stored front brackets and rear brackets may not be the same type of front brackets and rear brackets.

  In FIG. 1, the parenthesis type processing method storage memory 5 stores information on the types of operations to be performed according to the types of front brackets and rear brackets as shown in Table 2.

  In FIG. 1, the parenthesis multiplicity storage memory 8 stores the multiplicity of parentheses in the region currently being processed.

  In FIG. 1, the parenthesis insertion method storage memory 9 is for controlling the timing of changing the parenthesis multiplicity storage memory according to the types of parentheses and the pair of parentheses as shown in Table 3. Stores information.

  In FIG. 1, 10 parentheses processing method storage memory controls how the multiplicity storage memory for parentheses is changed according to the types of parentheses and their parentheses as shown in Table 4. It stores information for

  In such a configuration, the processing corresponding to “1. Parenthesis pair extraction processing” in FIG. 1 will be described according to the flowchart shown in FIG.

  In step S1, it is determined whether there is information that has not yet been processed among the information input by the information input means. As a result, if there is still unprocessed information, the process proceeds to S2, and if all the information has been processed, the parenthesis pair extraction process is terminated. In addition, although the following is described as reading from the information input means by sequential reading, it is not limited to this.

  In step S2, unprocessed information is read, and the process proceeds to step S3.

  In step S3, the information read in step S2 is checked against the parenthesis correspondence storage memory to determine whether the information has a front bracket or a rear bracket. As a result of the determination, the process proceeds to step S4 if it falls under the brackets, proceeds to step S5 if it falls under the brackets, and proceeds to step S1 if it does not fall under either.

  Note that in the case of “does not correspond to any of” in step S3, it matches the part of the first half of the parentheses consisting of multiple characters stored in the parenthesis correspondence storage memory, but it matches the whole. There is a case where it is not known whether or not it is correct (for example, even if “<T” is read, it is unknown whether or not it matches <TD *>). Therefore, in such a case, the details in the case of actually building a program in step S3 will be described in the following items 26 to 29.

  First, for each parenthesis stored in the parenthesis correspondence storage memory (hereinafter simply referred to as parentheses in this section to 29), the memory (hereinafter referred to as memory corresponding to the parentheses. The memory value corresponding to the class is denoted as C.). In the initial state, the memory values (= C) corresponding to all parentheses are set to 0.

  When the character of the (C + 1) th character of each parenthesis stored in the parenthesis correspondence storage memory is *, after adding 1 to the memory value corresponding to the parenthesis , 28 processing is performed.

  Then, the data read from the information input device is compared with the (C + 1) -th character of each parenthesis stored in the parenthesis correspondence storage memory. 1 is added to the memory value corresponding to. When the value of C corresponding to the parenthesis matches the length of the parenthesis, it is determined that the parenthesis is applicable.

  If the data read from the information input device does not match the (C + 1) -th character of each parenthesis stored in the parenthesis correspondence storage memory, it is stored in the parenthesis correspondence storage memory. The value of the memory corresponding to the parenthesis is reset to 0 unless the C character of the parenthesis is *. Thereafter, the process returns to the item 27 and the processing is continued.

  In step S4, the position of the first character, the position of the last character, and the type of parenthesis determined in step S3 are stored in the bracket storage memory.

  Note that the “type of parentheses” stored in step S4 means a numerical value indicating the type of the preceding parenthesis in the parenthesis correspondence storage memory (hereinafter, the type of parentheses is the parenthesis correspondence relationship). This is a numerical value indicating the type of parentheses corresponding to the storage memory).

  In step S5, first of all the data stored in the bracket storage memory, the first character position of the bracket, the position of the last character, and the type of brackets Is acquired, and the process proceeds to step S6.

  If reading from the information input means is premised on sequential reading, it is already sorted in the ascending order of position at the stage of storage in the memory, so there is no need to perform a separate sorting process. However, even if sequential reading is not premised, in step S5, the bracket storage memory is always sorted in ascending order of the first character position, last character position, and type in the brackets. As a result, it is possible to acquire information about the parentheses in descending order of the position by acquiring from the last stored in the memory.

  Usually, a certain minimum unit of information input from the information input device (for example, one character in the case of text, one byte in the case of a byte string, but not limited to this) is a certain bracket. And part of the parentheses, and not part of other front and rear parentheses. Therefore, when sorting by the position of the parentheses, the result is the same regardless of whether the first character position of the parentheses or the last character position of the parentheses is used.

  In step S6, using the type of parenthesis of the preceding parenthesis and the type of parenthesis of the rear parenthesis determined in step S3, the type of the parenthesis and rear parenthesis from the storage method storage memory according to the type of parenthesis The information on the type of operation to be performed is acquired according to, and the process proceeds to step S7.

  In step S7, if the numerical value of the type of operation performed in accordance with the type of brackets and brackets acquired in step S6 is -1, go to step S8, if 0, go to step S10, In this case, the process proceeds to step S11.

  In step S8, first, the position of the parenthesis obtained in step S5, the type of the parenthesis, and the type of the parenthesis determined in step S3 are the position of the parenthesis, the type, and the corresponding parenthesis. Stored in the bracket storage memory as the class type. Next, the position and type of parentheses, and the type of parentheses corresponding to the position and type of parentheses obtained in step S5, respectively. Is stored in the parenthesis storage memory, and the process proceeds to step S9.

The position of the parentheses (including the preceding parenthesis and the rear parenthesis) here refers to both the position of the first character and the position of the last character of the parentheses (hereinafter the same). When the parentheses are composed of only one character, the position of the first character and the position of the last character of the parentheses are the same.

  In step S9, the information on the brackets acquired in step S5 is deleted from the bracket storage memory, and the process returns to step S1.

  In step S10, the same process as in step S8 is performed (except for the part that proceeds to step S9), and the process proceeds to step S3.

  In step S11, the same process as in step S8 is performed (except for the part that proceeds to step S9), and the process proceeds to step S5.

  Next, “6. Parenthesis information output processing” in FIG. 1 will be described according to the flowchart shown in FIG.

  In step S21, the text to be processed (hereinafter referred to as original data or T), and the information stored in the bracket storage memory determined based on the original data or information equivalent thereto (hereinafter referred to as A) Obtain from memory or hard disk. For A, the parenthesis start position / end position / parenthesis type and the parenthesis type corresponding to the parenthesis are sorted in ascending order in that order.

  In the above, the ascending order of the types of parentheses means that the types of parentheses are ascending order of numerical values corresponding to the parentheses shown in Table 1: Parentheses correspondence storage memory.

  In step S22, the parenthesis multiplicity storage memory (hereinafter referred to as M) is set to 0. Also, specific information that is determined depending on the value of M and means that a specific area starts (hereinafter referred to as start information that depends on M), and that specific area ends. Specific information (hereinafter referred to as end information depending on M) is defined.

  The start information depending on M and the end information depending on M are, for example, an XML or HTML start tag (for example, “<SPAN CLASS =“ COLOR? ”>” :? And an end tag (for example, “</ SPAN>”) are conceivable, but are not limited thereto.

  In step S23, it is determined whether or not the next information exists in A. If there is the next information, the process proceeds to step S24. If there is no next information in A, the process proceeds to step S34.

  In step S24, the next information of A is read (this read data is set as B), and the process proceeds to step S25.

  In step S25, using the type of parentheses of B and the type of parentheses corresponding to the parentheses, a value corresponding to the two types of parentheses is acquired from the parenthesis insertion method storage memory. If the value is -1, the process proceeds to step S26, and if the value is 1, the process proceeds to step S27.

  In step S26, information from the beginning of the unprocessed portion of T to the position immediately before the start position of the brackets of B is output to the information output device, and the process proceeds to step S28.

  In step S27, information from the beginning of the unprocessed portion of T to the end position of the parentheses of B is output to the information output device, and the process proceeds to step S28.

  The unprocessed portion of T is a portion of the information processing apparatus that has not been output to the information output apparatus. Therefore, the part output to the information output device by the process of step S26 (or step S27) does not correspond to the “unprocessed part of T” in the subsequent process of step S26 (or steps S27, S34). Thus, the information after the next information becomes the output target to the information output device.

  In step S28, using the type of parentheses of B and the type of parentheses corresponding to the parentheses, a value corresponding to the two types of parentheses is acquired from the parenthesis processing method storage memory. If the value is -1, the process proceeds to step S29. If the value is 1, the process proceeds to step S31. If the value is 0, the process proceeds to step S33.

  In step S29, end information depending on M is output to the information output device, and the process proceeds to step S30.

  In step S30, after subtracting 1 from M, the process returns to step S23. If the result of subtracting 1 from M is negative, M remains 0.

  In step S31, 1 is added to M, and the process proceeds to step S32.

  In step S32, start information depending on M is output to the information output device, and the process returns to step S23.

  In step S33, do nothing and return to step S23.

  In step S34, the unprocessed portion of T is output to the information output device, and the bracket information output processing ends.

  Note that information about the front brackets and rear brackets that make up a pair is both immediately before and immediately after the front brackets, and immediately before and after the parentheses for the information input from the information input means. When the identification information is inserted into both, the following means are used.

  In the flowchart of FIG. 3, the process always proceeds from step S25 to step S26, and step S27 is deleted. Furthermore, for step S29, the parenthesis identification information (for example, a pair of HTML tags) depending on (M) is added before and after the parenthesis and output, and for step S31, before and after the front bracket. This can be realized by adding the bracket identification information (for example, a pair of HTML tags) depending on (M) and outputting.

  Next, “7. Screen display means” in FIG. 1 will be described according to the flowchart shown in FIG.

  In step S41, the text to be processed (hereinafter referred to as original data or T) and the information (hereinafter referred to as A) stored in the bracket storage memory determined based on the original data are acquired from the memory or the hard disk. To do. For A, the parenthesis start position / end position / parenthesis type and the parenthesis type corresponding to the parenthesis are sorted in ascending order in that order.

  In the above, the ascending order of the types of parentheses and the ascending order of the types of parentheses corresponding to the parentheses are the parenthesis types indicated in Table 1: Parentheses correspondence storage memory. It means that the corresponding numerical values are ascending.

  In step S42, the parenthesis multiplicity storage memory (hereinafter referred to as M) is set to 0. In addition, the screen display color is associated with the value of M in advance (for example, black if M = 0, red if M = 1, green if M = 2, purple if M = 3, M If it is = 4, it can be considered to be amber.)

  In step S43, it is determined whether or not the next information exists in A. If there is the next information, the process proceeds to step S44. If there is no next information in A, the process proceeds to step S49.

  In step S44, the next information of A is read (this read data is set as B), and the process proceeds to step S45.

  In step S45, using the type of parentheses of B and the type of parentheses corresponding to the parentheses, a value corresponding to the two types of parentheses is acquired from the parenthesis insertion method storage memory. If the value is -1, the process proceeds to step S46, and if the value is 1, the process proceeds to step S47.

  In step S46, the information from the beginning of the unprocessed part of T to the point immediately before the start position of the parentheses of B is displayed on the screen display means using the screen display color associated with the value of M. Proceed to S48.

  In step S47, the information from the beginning of the unprocessed part of T to the end position of the brackets of B is displayed on the screen display means using the screen display color associated with the value of M, and in step S48 move on.

  The unprocessed portion of T is a portion that has not been displayed on the screen display means in this information processing apparatus. Therefore, the part displayed on the screen display means by the process of step S46 (or step S47) will not correspond to the “unprocessed part of T” in the subsequent process of step S46 (or steps S47, S49). Thus, the information after the next information is displayed on the screen display means.

  In step S48, a value indicating the processing method is acquired from the parenthesis processing method related memory using the type of parenthesis of B and the type of parenthesis corresponding to the parenthesis, and the value is added to M. . Thereafter, the process returns to step S43.

  In step S49, the unprocessed portion of T is displayed on the screen display means using the screen display color associated with the value of M, and the screen display processing ends.

  In “7: Screen display processing”, only the screen display color in parentheses may be changed. In that case, in FIG. 4, the process always proceeds from step S45 to step S46. In step S46, the display is changed to display in the screen display color when M = 0, and step S47 is deleted.

  Furthermore, for step S48, a value indicating the processing method is obtained from the parenthesis processing method related memory using the type of parenthesis of B and the type of parenthesis corresponding to the parenthesis, and according to the value Separate processing methods.

  That is, when the value indicating the processing method is -1, the information from the start position to the end position of the brackets B is displayed on the screen display means in a color corresponding to M, and then the process value is set to the value M. When the value indicating the method is added, and the value indicating the processing method is other than -1, the value indicating the processing method is added to the value of M, and then the processing ends from the start position of the parentheses in (B) This can be realized by displaying the information up to the position on the screen display means in a color corresponding to (M).

  FIG. 5 is a functional block diagram showing an example for realizing the functions of the information processing apparatus according to the embodiment of the present invention.

The timing and the method of inserting (or creating) specific information can be appropriately controlled.

"Other embodiments"
In the memory for storing parenthesis correspondence relationship 2 in FIG. 1, even if it is a character other than the characters listed in Table 1, what is used as a pair for designating a certain range is “ The above processing can be performed by adding the pair to “characters in front brackets or rear brackets” and specifying an appropriate numerical value in the “type” column of Table 1.

  The processing from step S21 to step S23 in FIG. 2 is not necessarily performed by reading one character at a time. For example, there is no problem even if the corresponding pattern is automatically matched using a regular expression or the like, and the appearance portion of the corresponding pattern proceeds from step S24 or step S25 in order from the top. .

  The determination of whether the parenthesis or rear bracket in step S23 in FIG. 2 and the determination of whether or not the parentheses in step S8 in FIG. 3 are used in pairs are not necessarily two brackets in FIG. As shown in Table 1, it is not necessary to determine the class correspondence storage memory by using the numerical value in the “type” column, and it is not necessary to implement using the parenthesis correspondence storage memory. For example, there is no problem even if it is described by conditional branch processing or the like, and these mounting methods do not affect the above processing.

  The processing in steps S26 and S27 in FIG. 2 need not necessarily be determined by using the numerical value representing the type of operation as shown in Table 2 for the processing method storage memory for parentheses type 4 in FIG. In addition, there is no need to implement using the table shown in Table 2 in the first place. For example, there is no problem even if it is described by conditional branch processing or the like, and these mounting methods do not affect the above processing.
