It is a figure which shows the example of the hardware constitutions of a computer.

  FIG. 1 shows an outline of an internal configuration of an information processing apparatus according to an example of an embodiment of the present invention. 1 includes a document DB (database) 100, a phrase DB 110, an input reception unit 120, a target text acquisition unit 130, a candidate phrase acquisition unit 140, a candidate phrase processing unit 150, an output processing unit 160, and A candidate phrase insertion unit 170 is provided.

  The document DB 100 stores electronic documents. The document DB 100 may store a document used in a specific field, for example. Processing of each unit of the information processing apparatus 10 to be described later may be performed on a text (character string) in an electronic document stored in the document DB 100 as a processing target.

  The phrase DB 110 stores a plurality of phrases that appear in the electronic document stored in the document DB 100. Here, the phrase means an expression that can be understood as one unit in a document, such as a sentence or a phrase constituting the sentence. In the example of the present embodiment, a unit of a character string delimited by a preset delimiter is handled as one phrase. In this example, punctuation marks, question marks, exclamation marks, and line feed symbols are used as preset delimiters. The phrase DB 110 stores a character string constituting each phrase and the score of the phrase in association with each other. The score of each phrase is a numerical value indicating the importance of the phrase, and is obtained in advance based on the appearance frequency of the phrase in the electronic document stored in the document DB 100 and stored in the phrase DB 110. The appearance frequency of each phrase may be used as the score of each phrase as it is. Alternatively, for example, a value obtained by weighting the appearance frequency with a numerical value indicating usefulness predetermined for each phrase may be used as the score of the phrase. The usefulness of the phrase is determined according to the field of the contents of the electronic document stored in the document DB 100, for example. For example, it may be possible to predict phrases that are frequently used in documents in a particular field (medical, industrial, economic, legal, etc.). Therefore, when an electronic document in a specific field is stored in the document DB 100, the phrase that is predicted to be frequently used in the field is weighted with respect to the actual appearance frequency in the electronic document in the document DB 100, A value larger than the appearance frequency may be set as the score of the phrase. It is also conceivable that the usage frequency is predicted to be different among a plurality of phrases predicted to be frequently used. In such a case, the actual appearance frequency of each phrase may be weighted by reflecting the difference in use frequency. For example, it is only necessary to increase the weight of a phrase predicted to be used more frequently.

  Note that the appearance frequency of each phrase in the phrase DB 110 may change due to a change (such as new registration, update, or deletion) in the electronic document in the document DB 100. Therefore, the score of each phrase in the phrase DB 110 may be updated according to a change in the electronic document in the document DB 100 and a change in the appearance frequency of each phrase. The update of the score of each phrase in the phrase DB 110 may be performed, for example, when the electronic document in the document DB 100 is changed, may be performed at regular intervals, or is instructed by, for example, a user or an administrator The phrase DB 110 may be updated at the timing that is performed.

  The input receiving unit 120 receives user input via an input device such as a mouse and a keyboard. The input reception unit 120 passes the received input information to the target text acquisition unit 130 or the candidate phrase insertion unit 170 according to the content.

  The target text acquisition unit 130 acquires the text to be processed from the electronic document in the document DB 100 or the input text received by the input reception unit 120. The target text acquisition unit 130 acquires, for example, character strings before and after a position designated by the user in a text displayed on a display device (not shown) as a processing target. For example, referring to FIG. 2, on the display screen 200 in which the electronic document in the document DB 100 or the input text received by the input receiving unit 120 is displayed on the display device, the user moves the cursor to the position indicated by the arrow C using the input device. Are combined. In this example, the target text acquisition unit 130 acquires information indicating the position of the cursor via the input reception unit 120, and regards the cursor position as a specified position by the user, and acquires character strings before and after the specified position. . At this time, if an electronic document in the document DB 100 is displayed on the display screen 200, the corresponding character string is acquired from the document DB 100, and if the input text received by the input receiving unit 120 is displayed on the display screen 200. The corresponding character string is acquired from a temporary storage device (not shown) that stores the input text. The character string acquired at this time may be a character string between phrase delimiters that appear first in the forward and backward directions of the specified position. For example, by checking the forward and backward character strings one by one from the specified position and finding a preset phrase delimiter (punctuation mark, exclamation mark, question mark, new line symbol, etc.), the specified position and the delimiter Get string between characters. The delimiter used here may be the same as the delimiter set in advance to determine the phrase stored in the phrase DB 110 described above. In the example of FIG. 2, a sentence including a designated position “No significant lymphadenopathy is recognized” is acquired.

  In the description of the example of the present embodiment, the “front and back” character string at the designated position means the “left and right” character string at the designated position in a horizontally written document, and designated in a vertically written document. It means the character string "up and down" of the position.

  Referring to FIG. 1 again, the candidate phrase acquisition unit 140 includes a phrase including a character string before the specified position in the processing target text acquired by the target text acquisition unit 130 and its score, and the character after the specified position. The phrase including the column in the latter half and its score are acquired from the phrase DB 110. The phrase “a phrase including the character string before the specified position in the first half” is a phrase in which the character string starting from the first character of the phrase matches the character string before the specified position. The phrase “a phrase including the character string after the designated position in the latter half” is a phrase in which the character string ending with the last character of the phrase matches the character string after the designated position. Hereinafter, the phrase acquired by the candidate phrase acquisition unit 140 is also referred to as “candidate phrase”. It can be said that the candidate phrase is a phrase including a candidate for a character string to be inserted into the text to be processed.

  In the case of the example of the processing target text described with reference to FIG. 2 “significant lymphadenopathy is not recognized”, the candidate phrase acquisition unit 140 uses the character string “significant lymphadenopathy” before the specified position. "Is used as a search key to search the phrase DB 110 to obtain a phrase including the character string in the first half and its score. In this example, the candidate phrase acquisition unit 140 searches for and acquires the character string “significant lymphadenopathy” as a search key, and an example of the score is shown in FIG. Further, the candidate phrase acquisition unit 140 searches the phrase DB 110 using the character string “cannot be accepted” after the designated position as a search key, and acquires a phrase including the character string in the latter half and its score. In this example, the candidate phrase acquisition unit 140 searches for and acquires the character string “cannot be accepted” as a search key.

  Returning to the description of FIG. 1, the candidate phrase processing unit 150 performs processing on the candidate phrase acquired by the candidate phrase acquisition unit 140. For example, the candidate phrase processing unit 150 ranks the candidate phrases using the score acquired for each candidate phrase. Further, for example, the candidate phrase processing unit 150 deletes the character string included in the text to be processed from each candidate phrase. For example, in the case of the candidate phrase “significant lymphadenopathy or ascites accumulation is not recognized” in line L2 in FIG. 3, the character strings “significant lymphadenopathy” and “ "Cannot" is deleted from the candidate phrase, and the character string "and ascites reservoir" is generated. In addition, in the case of the candidate phrase “particularly no abnormality is recognized” in the row M1 in FIG. 4, the character string “not recognized” is deleted from the text to be processed, and the character string “particularly abnormal” is changed. Generate. More detailed processing of the candidate phrase processing unit 150 will be described later.

  The output processing unit 160 outputs the processing result of the candidate phrase processing unit 150. For example, the output processing unit 160 displays the candidate phrases after the candidate phrase processing unit 150 deletes the character strings included in the text to be processed on the display device (not shown) according to the ranking performed by the candidate phrase processing unit 150. Process to be displayed. For example, the output processing unit 160 generates display control information instructing display contents and modes, and outputs the generated display control information to the display device, thereby realizing display on the display device. Specific examples of display contents and modes by the output processing unit 160 will be described later.

  The candidate phrase insertion unit 170 identifies and identifies the candidate phrase selected by the user via the input reception unit 120 when the user selects one candidate phrase from the candidate phrases displayed by the output processing unit 160. The candidate phrase is inserted into the designated position of the text to be processed. If the text to be processed is acquired from the electronic document in the document DB 100, the identified candidate phrase is inserted at the designated position in the electronic document. If the text to be processed is acquired from the temporary storage device that stores the input text received by the input receiving unit 120, the identified candidate phrase is inserted at the designated position in the input text in the temporary storage device.

  Hereinafter, an example of processing of the information processing apparatus 10 will be described. FIG. 5 is a flowchart illustrating an example of a procedure of processing performed by the information processing apparatus 10. The information processing apparatus 10 starts the processing of the procedure in the example of FIG. 5, for example, when the user performs an input for designating a specific position in the text displayed on the display device.

  First, the input receiving unit 120 acquires a designated position in the text designated by the user using the input device (step S10).

  The target text acquisition unit 130 that has acquired the specified position from the input receiving unit 120 acquires the character string before and after the specified position and sets it as the processing target text (step S12). In the example of this embodiment, the target text acquisition unit 130 acquires a character string between a preset delimiter that first appears before and after the designated position and the designated position in step S12. The target text acquisition unit 130 passes the acquired processing target text to the candidate phrase acquisition unit 140.

  For the following processing procedure, an example of the text to be processed described above with reference to FIG. 2 "No significant lymphadenopathy is recognized" (the specified position is the cursor position indicated by the arrow c in FIG. 2). Will be described with reference to an example in which step S12 is acquired in step S12.

  The candidate phrase acquisition unit 140 acquires, from the phrase DB 110, candidate phrases that include character string candidates to be inserted into the processing target text received from the target text acquisition unit 130 (step S14). In step S <b> 14, for example, the candidate phrase acquisition unit 140 divides the candidate phrase at the specified position, and searches the phrase DB 110 using each of the character string before the specified position and the character string after the specified position as a search key. Then, the phrase including the character string before the designated position in the first half and the score thereof, and the phrase including the character string after the designated position in the second half and the score thereof are acquired from the phrase DB 110.

  In this example, in step S14, a set of candidate phrases and scores illustrated in the table of FIG. 3 is acquired as a phrase including the character string “significant lymphadenopathy” in the first half of the designated position and its score, Assume that a set of candidate phrases and scores exemplified in the table of FIG. 4 is acquired as a phrase including the character string “not allowed” after the specified position in the latter half and its score. With reference to FIG. 3 and FIG. 4, the candidate phrase including both the character string before the designated position and the character string after the designated position is acquired from the phrase DB 110 twice. For example, the candidate phrases “No significant lymphadenopathy” or “No significant lymphadenopathy or ascites accumulation” are recognized in the first half of the string before the specified position. It is acquired as a phrase including the character string after the designated position in the latter half part (see lines L1 and L2 in FIG. 3 and lines M2 and M3 in FIG. 4). In step S14, the same character string as the processing target text may be acquired (see line L1 in FIG. 3 and line M2 in FIG. 4).

  The candidate phrase acquisition unit 140 sends the candidate phrase acquired in step S14 and its score to the candidate phrase processing unit 150 together with information indicating whether the candidate string acquired before or after the designated position is included as a phrase. hand over.

  The candidate phrase processing unit 150 that has received the candidate phrase and its score from the candidate phrase acquisition unit 140 ranks the candidate phrases using the score of each candidate phrase (step S16). In the example of the present embodiment, in step S16, the candidate phrase processing unit 150 first uses the score of the candidate phrase depending on which character string before and after the designated position each candidate phrase includes. Determine a new score. Next, the candidate phrases are ranked in descending order of the new score determined for each candidate phrase.

The new score of each candidate phrase is calculated according to the following formula (1), for example.
S = s1 × α + s2 × β (1)

  In Expression (1), s1 represents a score of a candidate phrase including a character string before the designated position, and s2 represents a score of a candidate phrase including the character string after the designated position. α and β are weighting factors. The values of α and β may be constants set in advance, for example. Alternatively, the length of the candidate phrase to be calculated (number of characters included in the candidate phrase) may be used as the values of α and β. When using the length of the candidate phrase, α = β.

  When calculating the value S of the formula (1) for a candidate phrase including only one of the character strings before and after the designated position, s1 and The calculation is performed by substituting the score of the candidate phrase into one of s2 and substituting the value “0” into the other. In the case of a candidate phrase that includes both character strings before and after the designated position, the score of the candidate phrase is substituted for both s1 and s2. For example, in the case of the candidate phrase “no significant lymphadenopathy is found” in the row L1 in FIG. 3 and the row M2 in FIG. 4, the score is “189”, including the character string before the specified position, Since the character string after the designated position is included, S = 189 × α + 189 × β in equation (1). Also, in the case of the candidate phrase “significant lymphadenopathy or ascites accumulation is not recognized” in the row L2 in FIG. 3 and the row M3 in FIG. 4 (score is “167”), before and after the designated position Therefore, S = 167 × α + 167 × β in Equation (1). In addition, as an example of a candidate phrase including only the character string before the specified position, in the case of the line L3 “significant lymphadenopathy cannot be pointed out” in FIG. 3 (score is “105”), S in the expression (1) = 105 × α + 0 × β. As an example of a candidate phrase including only the character string after the designated position, in the case of the row M1 in FIG. 4 “particularly no abnormality is recognized” (score is “288”), S = 0 × α + 288 in Expression (1) × β.

  FIG. 6 shows an example of a new score determined according to the formula (1) for each candidate phrase exemplified in FIGS. 3 and 4. FIG. 6 is an example when α = 2.0 and β = 1.0 in the formula (1). In FIG. 6, the candidate phrases are shown in descending order of the determined new score. The candidate phrase processing unit 150 assigns a higher rank in the order of candidate phrases in rows K1 to K5 in the table of the example of FIG. 6 in step S16 of FIG.

  Returning to the description of the procedure in the example of FIG. 5, after step S <b> 16, the candidate phrase processing unit 150 deletes the character strings before and after the designated position from each candidate phrase (step S <b> 18). In step S18, the part which overlaps with a process target text is deleted in each candidate phrase. Therefore, for example, a candidate phrase composed of the same character string as the text to be processed “No significant lymphadenopathy is recognized” as shown in line K1 of FIG. The candidate phrase itself is deleted from. FIG. 7 shows an example of the result of performing the process of step S18 on each candidate phrase exemplified in FIG. Referring to FIG. 7, the line K <b> 1 (the same candidate phrase as the processing target text) in FIG. 6 does not exist in the table of the example in FIG. 7. Also, the phrases shown in the rows K2 to K5 in FIG. 7 are the portions overlapping the processing target text from the candidate phrases in the rows K2 to K5 in FIG. 6 (that is, the character string before the specified position in the processing target text and It is the one that deletes the following character string.

  Referring again to FIG. 5, candidate phrase processing unit 150 passes the results of the processing in steps S <b> 16 and S <b> 18 to output processing unit 160. The candidate phrase processing unit 150 further passes to the output processing unit 160 information indicating whether each candidate phrase is acquired from the phrase DB 110 as a phrase including a character string before or after the designated position.

  The output processing unit 160 performs a process of displaying each candidate phrase as a result of deleting a portion overlapping with the processing target text on a display device (not shown) according to the ranking given by the candidate phrase processing unit 150 (step S20). Moreover, in the example of this embodiment, in step S20, the output processing unit 160 has a different aspect depending on whether each candidate phrase is acquired from the phrase DB 110 as a phrase including any character string before or after the designated position. Each candidate phrase is displayed on the display device. That is, when each candidate phrase is acquired only as a phrase including (i) a character string preceding the specified position in the first half part, (ii) acquired only as a phrase including the character string after the specified position in the second half part. And (iii) when acquired as a phrase including the character string before the specified position in the first half and as a phrase including the character string after the specified position in the second half. Each candidate phrase is displayed in a different manner.

  FIG. 8 shows an example of a display screen displayed on the display device in step S20. In the example of FIG. 8, an original text display screen 200 including a text to be processed and a candidate phrase display screen 300 are displayed. The display screen 300 is arranged below the processing target text “No significant lymphadenopathy is recognized”. In addition, on the display screen 300, the candidate phrases “and ascites accumulation”, “particularly abnormal”, “cannot point out”, “cannot point out abnormalities such as“ cannot be pointed out ”in the table of the example of FIG. Are displayed in order of descending order determined in step S16. Among the candidate phrases in the display screen 300, “and ascites reservoir” are the cases (iii) above, and “particularly abnormal” is the case (ii), “is not pointed out” and abnormalities such as “ Cannot be pointed out ”corresponds to the case of (i) above. On the display screen 300, each candidate phrase is displayed in a frame of a different ground pattern depending on cases (i), (ii), and (iii). Each candidate phrase is arranged on the front side or the rear side of the designated position depending on which character string before or after the designated position of the processing target text is connected to the candidate phrase. For example, for the candidate phrase “particularly abnormal” corresponding to (ii), the character string after the designated position is connected thereafter, and the character string before the designated position is not connected. The candidate phrase is arranged on the front side of the designated position. In addition, since the other three candidate phrases are all connected after the character string before the designated position, they are arranged behind the designated position.

  As a modification of the display screen 300 of FIG. 8, instead of displaying each candidate phrase in a frame of a different ground pattern depending on the cases (i), (ii), and (iii), May be displayed. In yet another example, each candidate phrase may be displayed in a different character color or font depending on cases (i), (ii), and (iii).

  FIG. 9 shows another example of the display screen displayed on the display device in step S20. In the example of FIG. 9, an original text display screen 200 including a processing target text and a candidate phrase display screen 302 are displayed. The display screen 302 is arranged below the processing target text “No significant lymphadenopathy is recognized” with the upper left corner aligned with the designated position. In the display screen 302, as in the display screen 300 in the example of FIG. 8, the candidate phrases “and ascites accumulation”, “particularly abnormal”, “cannot be pointed out”, “cannot point out abnormalities” are determined in step S16. Are displayed in descending order. In the display screen 302, the character strings of “before”, “after”, and “before” shown in association with each candidate phrase are any of the above-mentioned (i), (ii), and (iii) It depends on the case. The candidate phrase “and ascites reservoir” corresponding to the above (iii) follows the character string “significant lymphadenopathy” before the specified position of the processing target text, and further after the candidate phrase, The string “is not allowed” follows the specified position. From this, the character string “front and rear” indicating that the candidate phrase is connected to the character strings “front” and “rear” at the designated position is shown in association with the candidate phrase “and ascites reservoir”. In addition, the candidate phrase “particularly abnormal” corresponding to the above (ii) is connected before the character string “not allowed” after the specified position of the text to be processed, and the character string before the specified position is Not connected. A character string “after” indicating this is shown in association with the candidate phrase “particularly abnormal”. In addition, the candidate phrases corresponding to the above (iii) “cannot be pointed out” and “cannot point out abnormalities such as” follow the character string “significant lymphadenopathy” before the specified position of the text to be processed, respectively. Connected and not connected to the string after the specified position. A character string “previous” representing this is shown in association with each of these candidate phrases.

  In addition, in the display screen 302 of FIG. 9, as a modification, candidate phrases are placed in different background patterns or color frames depending on which case corresponds to (i), (ii), or (iii). Candidate phrases may be displayed in different character colors or fonts.

  Referring to FIG. 5 again, the input receiving unit 120 receives a selection by one user from the candidate phrases displayed in step S20 (step S22). In step S22, for example, the user who has confirmed the candidate phrase display screen illustrated in FIG. 8 or FIG. 9 inputs an instruction to select one of the candidate phrases on the display screen using the input device. In this case, the input receiving unit 120 receives the input. The input receiving unit 120 passes information for specifying the selected candidate phrase to the candidate phrase inserting unit 170.

  The candidate phrase insertion unit 170 that has received the information specifying the selected candidate phrase from the input receiving unit 120 inserts the selected candidate phrase at the designated position in the processing target text (step S24). After step S24, the process of the procedure in the example of FIG. 5 ends.

  Note that the processing example described above with reference to FIG. 5 is merely an example of the processing procedure of the information processing apparatus 10, and is not limited to the example described above. For example, in the procedure of the example of FIG. 5, the order of processing in step S16 and step S18 may be switched. That is, after deleting the part which overlaps with a process target text from each candidate phrase acquired by step S14 (step S18), you may rank each candidate phrase as mentioned above with reference to step S16. . In this example, after the candidate phrases that are the same as the processing target text are excluded from the candidate phrases acquired in step S14, a new score for each candidate phrase is determined and ranked.

  As another modification of the procedure of the example of FIG. 5, instead of determining and ranking the new scores for each candidate phrase in step S16, only the process of determining the new scores for each candidate phrase may be performed. In the case of this example, when candidate phrases are output in step S20, the output processing unit 160 may rank and output the candidate phrases in descending order of the new score.

  As yet another modification, instead of always performing the process of inserting the selected candidate phrase into the designated position of the processing target text in step S24, the candidate phrase includes any character string before and after the designated position. Depending on whether the phrase is acquired as a phrase, a part of the text to be processed may be replaced with a candidate phrase. For example, referring to FIG. 9, when the candidate phrase “and ascites reservoir” connected to the character string before and after the character string at the designated position is selected, it is inserted at the designated position and after the character string at the designated position. When the candidate phrase “particularly abnormal” connected only to the character string is selected, the character string “significant lymphadenopathy” before the designated position is replaced with the candidate phrase “particularly abnormal”. In addition, if the candidate phrase “cannot be pointed out” or “cannot point out abnormalities such as” that is connected only to the character string before the character string at the specified position is selected, the character string “after the specified position is accepted. Replace “No” with the selected candidate phrase.

  The information processing apparatus 10 exemplified above is typically realized by executing a program describing functions or processing contents of each unit of the information processing apparatus 10 described above on a general-purpose computer. In the computer, for example, as shown in FIG. 10, a CPU (central processing unit) 80, a memory (primary storage) 82, various I / O (input / output) interfaces 84, and the like are connected via a bus 86 as hardware. Circuit configuration. Also, a disk drive 90 for reading a portable nonvolatile recording medium of various standards such as a hard disk drive (HDD) 88, a CD, a DVD, or a flash memory via the I / O interface 84, for example, to the bus 86. Connected. Such a drive 88 or 90 functions as an external storage device for the memory. A program in which the processing content of the embodiment is described is stored in a fixed storage device such as the HDD 88 via a recording medium such as a CD or DVD or via a network, and is installed in a computer. The program stored in the fixed storage device is read into the memory and executed by the CPU, whereby the processing of the embodiment is realized.

  In the above, the embodiment of the example in which the information processing apparatus 10 is realized by one computer has been described. However, the various functions of the above-described example of the information processing apparatus 10 may be realized by being distributed to a plurality of computers. Good.
