The present invention relates to a technical map output device that automatically outputs a technical map from a document, such as a device that receives an item editing instruction and performs a classification change process that changes the classification according to the editing instruction.

A bubble chart as shown in FIG. 25 (a) may be used to analyze a large number of technical documents such as patents and papers. Such a diagram is called a technical map. This bubble chart is a diagram in which the viewpoints of two analyzes are taken on two axes, vertical and horizontal, items are arranged on each axis, and bubbles of a size based on the number of documents related to the item are arranged at the intersection of each item. .. For example, by creating a technical map centered on "problems" and "solutions" with the analysis target as a patent, it is possible to get a bird's-eye view of what kind of technological development is being carried out. The technology map does not necessarily have to be a bubble chart, but may be a diagram in which the number of documents is plotted instead of the bubbles in FIG. 25 (a), and is an intersection of items as shown in FIG. 25 (b). It may be a table in which specific document names are plotted in cells. Further, the technical map may be a three-dimensional bubble chart in which the viewpoints of the three analyzes are the X-axis, the Y-axis, and the Z-axis.

Conventionally, a part in which a "problem" or a "solution" is described from a technical document (for example, [effect of the invention] in the case of a patent document) is specified, and the content of the specified part of a plurality of technical documents is There was a system that automatically generated a technical map by performing clustering (see, for example, Patent Document 1).

On the other hand, in the tabular technical map, there is a device or the like that interactively classifies documents by reflecting the modification of the classification result made by the user in the mechanical document classification method (see, for example, Patent Document 2).

JP-A-2007-108867 (Page 1, Figure 1, etc.) Japanese Unexamined Patent Publication No. 2008-305268 (Page 1, Fig. 1, etc.)

However, in the system such as Patent Document 1, once the apparatus outputs the technical map, there is a problem that the user cannot edit the technical map such as adding or deleting the item of the axis.

Further, in the device such as Patent Document 2, there is a problem that the document belonging to each item of the technical map can be changed, but the item itself of the technical map cannot be edited.

The technical map output device of the first invention identifies a document information storage unit that stores two or more document information corresponding to a document identifier that identifies a document, and two or more items of each axis of two or more dimensions.

Further, in the technical map output device of the second invention, the editing instruction is an item integration instruction for combining two or more items into one item, and the axis change unit is an item integration instruction for the first invention. According to this, two or more item identifiers are changed to one item identifier, and the classification change unit associates two or more document identifiers corresponding to the item identifiers corresponding to each of the two or more items with one item identifier. It is a technology map output device to be changed so as to be.
With such a configuration, the user can integrate the items of the technology map.

Further, in the technical map output device of the third invention, the editing instruction is an item deletion instruction for deleting at least one item with respect to the first invention, and the axis changing unit follows the item deletion instruction. The classification change unit is a technical map output device that deletes one item identifier and changes one or more document identifiers corresponding to one item identifier so as not to correspond to one item identifier.
With such a configuration, the user can delete the item of the technical map.

Further, in the technical map output device of the fourth invention, for the third invention, the classification change unit analyzes each document information identified by one or more document identifiers corresponding to one item identifier.

Hereinafter, embodiments of the technical map output device and the like will be described with reference to the drawings. In addition, since the components with the same reference numerals perform the same operation in the embodiment, the description may be omitted again.

(Embodiment 1)
In this embodiment, patent map output that automatically extracts two or more items of axes of each of two or more dimensions from two or more patent documents, configures the axes, classifies patent documents, and outputs a patent map. A technical map output device 1 for receiving an item editing instruction and performing a classification change process for changing the classification according to the editing instruction will be described.

FIG. 1 is a block diagram of the technical map output device 1 according to the present embodiment.

The technology map output device 1 includes a storage unit 11, a correspondence determination unit 12, a technology map configuration unit 13, a technology map output unit 14, an edit instruction reception unit 15, an axis change unit 16, and a classification change unit 17.

The storage unit 11 includes a document information storage unit 111, an item identifier storage unit 112, and a document identifier storage unit 113.

The document information storage unit 111 stores two or more document information corresponding to the document identifier that identifies the document.

Here, the document may be any document as long as it can be classified on the technical map such as a patent document or a paper. The patent document may be a patent publication gazette, a patent publication gazette, or a document at the time of filing a patent application, and its format does not matter. Further, in addition to patent documents and papers, for example, a web page introducing a product, a newspaper article containing product information, a press release of a company, or the like may be used.

The document identifier is a symbol string that identifies a document. The document identifier may be any symbol string as long as the document can be uniquely defined in the document information storage unit 111. For example, if the document is a published patent gazette, it is preferable to use the patent application number or patent publication number, and if the document is a patent publication gazette, it is preferable to use the patent number. Further, the structure of the document information corresponding to the document identifier does not matter. Usually, the document information corresponding to the document identifier includes text. Further, the document information may include information regarding the structure of the document. For example, the text and its structure may be represented by using a markup language such as HTML, or the structure of the document may be represented by square brackets as in a patent document. Further, the document information may include the meta information of the document. The meta information is, for example, information on a patent document other than a text such as an applicant, an inventor, an agent, a filing date, a publication date, an IPC, an FI, and an F-term.

The item identifier storage unit 112 stores an item identifier that identifies two or more items of each axis having two or more dimensions.

Here, each axis having two or more dimensions is a "viewpoint" that is the axis of the technical map. For example, in the case of the two-dimensional technical map shown in FIG. 25 (a), the "problem" and the "solution means" are the axes. Further, the axis item is a character string, a symbol, or an image arranged on the axis of the technical map. For example, in the case of the two-dimensional technical map of FIG. 25A, the items are "strong wind countermeasures" and "lightning strike countermeasures" on the task axis, and "pitch control" and "variable speed control" on the solution axis. The item identifier storage unit 112 may include an item identifier of an item that is not displayed on the technical map. For example, in the technical map output device 1 that outputs the technical map of FIG. 25A, the item identifier storage unit 112 may include item identifiers such as "power generation efficiency" and "manufacturing cost reduction" as items of the problem axis. ..

The document identifier storage unit 113 stores one or more document identifiers in association with two or more item identifiers corresponding to each of the two or more dimensions.

The document identifier storage unit 113 contains the contents of the technical map (for example, a bubble in the case of a bubble chart, the number of cases in the case of a number map displaying the number of cases instead of the bubble, and a document included in the cell in the case of a table as shown in FIG. 25B). The document identifier of the document corresponding to each item in each dimension is stored to generate the list). That is, when the technical map output device 1 outputs the technical map of the bubble chart, for example, the document identifier associated with the item identifier of the item on the horizontal axis and the document identifier associated with the item identifier of the item on the vertical axis. The size of the product set of is reflected in the size of the bubble.

The correspondence determination unit 12 analyzes each document information of two or more dimensions, acquires an item identifier corresponding to each dimension of two or more dimensions for each document information, and obtains a document identifier for identifying the document information in each dimension of two or more dimensions. It is stored in the document identifier storage unit 113 in association with two or more item identifiers corresponding to.

There is no limitation on the algorithm in which the correspondence determination unit 12 analyzes the document information stored in the document information storage unit 111 and acquires the item identifier corresponding to the document information. The correspondence determination unit 12 may acquire the item identifier corresponding to each document information by referring to the information of the item identifier storage unit 112, or may not refer to the information of the item identifier storage unit 112 and may obtain the item from the document information. An identifier may be generated.

When acquiring the item identifier corresponding to each document information by referring to the information of the item identifier storage unit 112, the correspondence determination unit 12 stores each document information stored in the document information storage unit 111 and the item identifier storage unit 112. Compare each stored item identifier and determine the correspondence between the document information and the item identifier.

For example, the number of times the item name (item identifier when the item identifier is output to the technical map as it is) appears in the text of each document is calculated, and when the number of times is equal to or more than a predetermined value, the document of the document. The identifier may be associated with the item identifier of the item. Further, it may be associated with the item identifier of one item that appears most frequently in the text. Further, instead of the number of times the item name appears, the item name may be divided into characters or morphemes, and the total number of times each character or morpheme appears may be used. Further, a thesaurus may be used when calculating the number of times the name of the item or the morpheme appears. Specifically, the name of the item, the hypernym of the morpheme, the hyponym, or both of them may be obtained from the thesaurus, and the number of times that the word obtained from the thesaurus appears in the text of each document may be used.

Further, the correspondence may be performed using a corpus. For example, the technical map output device 1 collects a document group including an item name (an item identifier when the item identifier is output to the technical map as it is) from the corpus for each item stored in the item identifier storage unit 112. After converting each document included in the document group into a vector, all of the vectors or a vector (for example, an average vector) representing the document group is stored in advance. When the correspondence determination unit 12 associates the document identifier with the item identifier, the document information corresponding to the document identifier is vectorized by the same method (hereinafter referred to as the document information vector), and the document information vector and each item are linked. The degree of similarity may be obtained, and when the degree of similarity is equal to or higher than a predetermined value, the document identifier and the item identifier may be associated with each other. Here, as a method of vectorizing a document, a method of vectorizing n-gram (n ≧ 1) of characters and words and other attributes of the document information as dimensions, their appearance frequency and TF-IDF as values. And so on. For the similarity between the document information vector and the item, a method using the cosine similarity between the document information vector and the average vector of the items stored in advance, the Pearson correlation coefficient, the deviation pattern similarity, etc. Among the vectors of the items stored in advance, n high-order vectors close to the document information vector may be acquired, and the similarity may be calculated using the distance between the acquired vector and the document information vector (that is, near k). You may use the method). Further, in the correspondence between the document identifier and the item identifier, the document identifier may be associated with the item having the highest degree of similarity. Since the vectorization method, similarity, and k-nearest neighbor method are known techniques, description thereof will be omitted.

In addition, for example, as a method of associating using a corpus, in the corpus, a document containing an item name (an item identifier when the item identifier is output as it is on the technical map) is a correct example, and a document that does not include the item identifier. As a negative example, a discriminator that discriminates between a positive example and a negative example may be learned, and the result output by the discriminator may be used as it is (for example, SVM or Random Forest). Further, using the positive example and the negative example, a classifier (for example, SVR or Random Forest) that outputs a value (hereinafter, score) such as a probability of being a positive example is learned and stored in the document information storage unit 111. A discriminator may be applied to each document, and the score output by the discriminator may be used for association. At this time, the document identifier may be associated with the item identifier corresponding to the discriminator that achieves the highest score, as in the method of associating without using the corpus, and the score is predetermined. It may be associated with the item identifier corresponding to all the classifiers that achieve a certain value or more. Since the above SVM, SVR, and Random Forest are known techniques, the description thereof will be omitted.

Further, when the item identifier is generated from the document information without referring to the information of the item identifier storage unit 112, the correspondence determination unit 12 generates the item identifier only from each document information stored in the document information storage unit 111. For example, the item identifier can be generated by equipping the technical map output device 1 with an important expression acquisition unit and an item aggregation unit (not shown). Here, the important expression acquisition unit has a function of acquiring expressions related to each axis from the document information. For example, important expressions related to the "task" axis are expressions such as "can do XX" and "achieve △△". The important expression extraction unit is, for example, Sakai's method (Hiroyuki Sakai, Hiroshi Nonaka, Shigeru Masuyama, Extraction of technical problem information from patent specifications, Journal of the Japanese Society for Artificial Intelligence, Vol. 25, No. 6 I, pp.531- It can be realized by using 540, 2009.) and so on. In addition, the item aggregation unit has a function of shortening and further summarizing each expression extracted by the important expression extraction unit. For example, the item aggregation department shortens the important expression "the resources used can be reduced" to "resource reduction", and further summarizes "resource reduction" and "improvement of reusability" into "recyclability". .. The item aggregation section is, for example, Hiroki Sakaji, Yusuke Suzuki, Hiroyuki Sakai, Shigeru Masuyama, Extraction of the effect and the technology terms from a patent document, Proc. Of 40th International Conference on Computers. It can be realized by using and Industrial Engineering (CIE40), cie214jp-1, Awaji-shima, Japan, (2010).). In this case, the correspondence determination unit 12 registers the item identifier generated from the document information in the item identifier storage unit 112.

The technical map configuration unit 13 configures an axis having two or more item identifiers of each axis of two dimensions or more, and uses the document identifier corresponding to the item identifier of each axis to display the content information which is the content of the technical map. Configure and configure a technology map with axes and content information.

Here, the content information is information necessary for outputting the technical map. For example, in the case of a technical map as shown in FIG. 25 (a), it is information for forming a bubble. Specifically, in the above case, the content information includes at least the radius of the bubble according to the number of documents. Here, the radius of the bubble usually increases in proportion to the size of the number of documents. Further, in the case of the technical map as shown in FIG. 25 (b), it is a list of documents described in each cell. Further, the content information includes the number of documents in the case of a technical map that plots the number of documents contained in the bubble together with or instead of the bubble in FIG. 25 (a). Furthermore, if you plot a bar graph instead of a bubble, it is the information that makes up the bar graph. Usually, the information constituting the bar graph includes the height of the bar graph. Also, the height of the bar graph usually increases in proportion to the size of the number of documents. As described above, the required information differs depending on the shape of the technical map to be output.

The technical map configuration unit 13 reconstructs the content information of the technical map according to the change of the item identifier storage unit 112 by the axis change unit 16 described later and the change of the document identifier storage unit 113 by the classification change unit 17 described later. .. At this time, the technical map configuration unit 13 has content information conforming to the shape of the technical map to be output, as before the axis change unit 16 and the classification change unit 17 change the item identifier storage unit 112 and the document identifier storage unit 113. To configure.

The technology map output unit 14 outputs a technology map. Since the method of outputting the technical map from the content information configured by the technical map configuration unit 15 is a known technique, the description thereof will be omitted.

Here, the output means display on a display, projection using a projector, printing by a printer, transmission to an external device, storage on a recording medium, processing result to another processing device, another program, or the like. It is a concept that includes delivery.

When the technology map configuration unit 13 reconstructs the content information, the technology map output unit 14 reoutputs the technology map based on the reconstructed content information.

The editing instruction receiving unit 15 receives an editing instruction which is an instruction to edit an axis item of the technical map output by the technical map output unit 14.

The editing instructions are, for example, an item integration instruction that combines two or more items into one item, an item deletion instruction that deletes at least one item, an item addition instruction that adds an item, and an item name change instruction that changes the item name. Is.

The input means may be anything such as a mouse, a touch panel, a numeric keypad, a keyboard, or a menu screen.

The axis changing unit 16 changes the axis according to the editing instruction received by the editing instruction receiving unit 15.

When the editing instruction receiving unit 15 receives the item integration instruction, the axis changing unit 16 changes two or more item identifiers into one item identifier according to the item integration instruction. For example, when the item integration instruction includes two or more item identifiers that are the integration source (hereinafter, integration source item identifier) and one item identifier that is the integration destination (hereinafter, integration destination item identifier), the axis change unit 16 Deletes the integration source item identifier from the item identifier storage unit 112, and newly stores the integration destination item identifier in the item identifier storage unit 112. Further, when the item integration instruction includes only the integration source item identifier, the axis change unit 16 may automatically generate the integration destination item identifier from the integration source item identifier. For example, the axis changing unit 16 may connect the integration source item identifier with a predetermined connection character string (for example, “·”), and use the connected identifier as the integration destination item identifier. Further, for example, the axis changing unit 16 may acquire or generate a hypernym of the integration source item identifier using a thesaurus and use it as the integration destination item identifier.

Further, when the edit instruction receiving unit 15 receives the item deletion instruction, the axis changing unit 16 deletes one item identifier according to the item deletion instruction. For example, the axis changing unit 16 deletes the item identifier specified in the item deletion instruction from the item identifier storage unit 112.

Further, when the edit instruction receiving unit 15 receives the item addition instruction, the axis changing unit 16 adds an item identifier that identifies the item corresponding to the item addition instruction to the item identifier storage unit 112. For example, the axis changing unit 16 adds the item identifier specified in the item addition instruction to the item identifier storage unit 112.

Further, when the edit instruction receiving unit 15 receives the item name change instruction, the axis change unit 16 changes the item identifier of the item corresponding to the item name change instruction. For example, the axis change unit 16 changes the item identifier specified by the item name change instruction in the item identifier storage unit 112. Here, when the item identifier represents the name of the item, the axis changing unit 16 changes the item identifier itself.

The classification change unit 17 changes the correspondence of the document identifier related to the item corresponding to the edit instruction among the one or more document identifiers of the document identifier storage unit 113 to the item identifier according to the change of the axis.

Here, the related document identifier usually differs depending on the editing instruction received by the editing instruction receiving unit 15. When the edit instruction received by the edit instruction receiving unit 15 is an item integration instruction, an item deletion instruction, or an item name change instruction, the item identifier included in each edit instruction and the document identifier to which the currently associated document identifier is related are used. Become. On the other hand, when the editing instruction received by the editing instruction receiving unit 15 is an item deletion instruction, the related document identifier is the related document identifier for all the document identifiers stored in the document information storage unit 111.

When the editing instruction received by the editing instruction receiving unit 15 is an item integration instruction, the classification changing unit 17 is, for example, all of the document identifiers associated with the two or more item identifiers to be integrated specified in the item integration instruction. Is deleted from the document identifier storage unit 113, and then all of the document identifiers are associated with the item identifiers of the integration destination. Further, for example, the classification change unit 17 deletes all the document identifiers associated with the two or more item identifiers to be integrated specified in the eye integration instruction from the document identifier storage unit 113, and then the document information storage unit. For all the document information stored in 111, the item identifier of the integration destination and the corresponding document identifier may be determined by the same method as that of the correspondence determination unit 12.

When the edit instruction received by the edit instruction receiving unit 15 is an item deletion instruction, the classification change unit 17 uses, for example, a document identifier corresponding to the item identifier corresponding to the item deletion instruction (hereinafter referred to as a deletion target item identifier). Delete from the storage unit 113. Further, for example, the classification change unit 17 deletes the document identifier from the document identifier storage unit 113, and then the document identifier corresponding to the deletion target item identifier, or all the document identifiers stored in the document information storage unit 111. , Each document identifier may be associated with an item identifier other than the deletion target item identifier by using the same method as that of the correspondence determination unit 12.

When the editing instruction received by the editing instruction receiving unit 15 is an item addition instruction, the classification changing unit 17 may, for example, refer to the correspondence determination unit 12 for the document identifier corresponding to all the document information stored in the document information storage unit 111. Use the same method to associate with the added item identifier. Here, when the correspondence determination unit 12 associates one item identifier with one document identifier, regarding the document identifier associated with the added item identifier, the correspondence with the item identifier other than the added item identifier is a document. Deleted from the identifier storage unit 113.

When the editing instruction received by the editing instruction receiving unit 15 is an item name change instruction, the classification changing unit 17 is instructed by, for example, the item name changing instruction stored in the item identifier storage unit 112 and the document identifier storage unit 113. Change the item identifier.

The storage unit 11, the document information storage unit 111, the item identifier storage unit 112, and the document identifier storage unit 113 are preferably non-volatile recording media, but can also be realized by volatile recording media.

The process in which information is stored in the storage unit 11, the document information storage unit 111, the item identifier storage unit 112, and the document identifier storage unit 113 does not matter. For example, the information may be stored in the storage unit 11, the document information storage unit 111, the item identifier storage unit 112, and the document identifier storage unit 113 via the recording medium, and is transmitted via a communication line or the like. Information may be stored in the storage unit 11, the document information storage unit 111, the item identifier storage unit 112, and the document identifier storage unit 113, or the information input via the input device may be stored in the storage unit 11, It may be stored in the document information storage unit 111, the item identifier storage unit 112, and the document identifier storage unit 113.

The correspondence determination unit 12, the technical map configuration unit 13, the axis change unit 16, and the classification change unit 17 can usually be realized from an MPU, a memory, or the like. The processing procedure of the correspondence determination unit 12, the technical map configuration unit 13, the axis change unit 16, and the classification change unit 17 is usually realized by software, and the software is recorded in a recording medium such as ROM. However, it may be realized by hardware (dedicated circuit).

In the present embodiment, the technology map output device 1 outputs a bubble chart type technology map. Further, in the item identifier storage unit 112 and the document identifier storage unit 113, the item identifier represents the name of the item itself to be displayed on the technical map. Further, in the document identifier storage unit 113, one document identifier is associated with one item identifier in each axis.

Further, in the present embodiment, the editing instruction receiving unit 15 receives four types of editing instructions: an item integration instruction, an item deletion instruction, an item addition instruction, and an item name change instruction. Here, the item integration instruction includes two or more item identifiers to be integrated and one item identifier after integration. Further, the item deletion instruction includes one item identifier to be deleted. In addition, the item addition instruction includes one item identifier to be added. Further, the item name change instruction includes one item identifier to be changed and an item identifier after the change (that is, an item identifier before the change and an item identifier after the item identifier is changed).

Further, in the present embodiment, when the item integration instruction is instructed, the technical map output device 1 is one after integrating the document identifiers associated with the two or more item identifiers to be integrated. Corresponds to the item identifier.

Further, when the item addition instruction is instructed, the technical map output device 1 associates all the document information stored in the document information storage unit 111 with the item identifier to be added, and the document information is added. When corresponding to the item identifier, the association between the document identifier corresponding to the document information and the item identifier associated immediately before the item addition instruction is instructed is deleted, and a new item addition instruction is instructed. Corresponds to the item identifier (item identifier to be added).

(Step S201) The correspondence determination unit 12 associates the document stored in the document information storage unit 111 with the item identifier stored in the item identifier storage unit 112, and stores the information in the document identifier storage unit 113. Such a process is called a correspondence determination process. The details of the correspondence determination process will be described with reference to the flowchart of FIG.

(Step S205) If the editing instruction received in step S204 is an item integration instruction, the editing instruction receiving unit 15 proceeds to step S206. If not, the process proceeds to step S207.

(Step S206) The axis changing unit 16 combines two or more item identifiers specified in the item integration instruction into one item identifier. Further, the classification change unit 17 stores the information of the document identifier storage unit 113 so as to correspond to the new item identifier in which all the document identifiers associated with the two or more item identifiers specified in the item integration instruction are combined. change.

(Step S207) If the editing instruction received in step S204 is an item deletion instruction, the editing instruction receiving unit 15 proceeds to step S208. If not, the process proceeds to step S209.

(Step S208) The axis change unit 16 and the classification change unit 17 change the information of the item identifier storage unit 112 and the document identifier storage unit 113 according to the item deletion instruction. Such a process is called an item deletion process. The details of the item deletion process will be described with reference to the flowchart of FIG.

(Step S209) If the editing instruction received in step S204 is an item addition instruction, the editing instruction receiving unit 15 proceeds to step S210. If not, the process proceeds to step S211.

(Step S210) The axis change unit 16 and the classification change unit 17 change the information of the item identifier storage unit 112 and the document identifier storage unit 113 according to the item addition instruction. Such processing is called item addition processing. The details of the item addition process will be described with reference to the flowchart of FIG.

(Step S211) If the editing instruction received in step S204 is an item name change instruction, the editing instruction receiving unit 15 proceeds to step S212. If not, the process returns to step S204.

(Step S212) The axis changing unit 16 changes the item identifier stored in the item identifier storage unit 112 and the document identifier storage unit 113 based on the item name change instruction received in step S204.

In the flowchart of FIG. 2, the process ends when the power is turned off or an interrupt for the end of the process occurs.

Next, a specific example of the details of the correspondence determination process in step S201 will be described with reference to the flowchart of FIG.

(Step S308) The correspondence determination unit 12 proceeds to step S309 if the k-th item (hereinafter, item [k]) of the i-th axis exists, and to step S313 if not.

(Step S309) The correspondence determination unit 12 substitutes the score between the document [j] and the item [k] into the variable s. Here, the score is a score indicating the plausibility that the document [j] belongs to the item [k], and the larger the value, the more the document [j] belongs to the item [k]. Value may be used. The specific calculation method of the score will be described later.

(Step S310) If the s obtained in step S309 is larger than score, the correspondence determination unit 12 proceeds to step S311, and if not, proceeds to step S312.

(Step S311) The correspondence determination unit 12 substitutes s for score and further substitutes the item [k] for item.

(Step S312) The correspondence determination unit 12 increases the counter k by 1 and returns to step S308.

(Step S314) The correspondence determination unit 12 increases the counter j by 1 and returns to step S304.

In the flowchart of FIG. 3, any score may be used as long as the score is such that the larger the value is, the more the document and the item are determined to be “corresponding”.

For example, the number of times a character string representing an item (item identifier in the present embodiment) appears in a document may be used as a score. Further, the character string representing the item may be morphologically analyzed, and the total number of times each morpheme appears may be used as a score.

Further, for example, a method of obtaining a score using a corpus may be learned. Specifically, documents including character strings representing items are collected from the corpus, these documents are converted into word or n-gram vectors, and the average vector is obtained in advance. When obtaining the score between the document and the item, there is a method of using the cosine similarity between the average vector and the vector of the document as the score. Further, a discriminator for discriminating between a positive example and a negative example may be learned by using a document containing a character string representing an item as a positive example and a document not as a negative example, and the score output by the discriminator may be used as it is (. For example, Random Forest) that outputs SVR and probability.

(Step S406) The technology map component 13 calculates the radius of the bubble based on the size of D. Usually, the radius is determined so that the area of the bubble is proportional to the size of D. Specifically, when the radius when the size of D is 1 is I, the radius when the size of D is n is I × (square root of n).

(Step S407) The technical map configuration unit 13 increases i by 1 and returns to step S402.

The flowchart of FIG. 4 is for outputting a two-dimensional technical map, but the same applies to the case of outputting a three-dimensional or higher technical map. For example, when outputting a three-dimensional technical map, the item [i] on the first axis, the item [j] on the second axis, and the item [k] on the third axis (i, j, k are respectively). All the documents associated with all of 1 to the last item of each axis) are acquired and assigned to D, and the radius of the bubble is calculated based on the D.

(Step S504) If the i-th document (hereinafter, document [i]) exists in D, the classification change unit 17 proceeds to step S505. If not, it returns to the higher-level processing.

(Step S505) The classification change unit 17 associates the document [i] with the item that achieves the highest score, and stores it in the document identifier storage unit 113. This step is usually associated with the item having the highest score by the same processing as in steps S307 to S313 of the correspondence determination process of FIG. At this time, it is assumed that the target axis is the same axis as the deletion target item.

(Step S506) The classification changing unit 17 increases the counter i by 1, and returns to step S504.

Next, a specific example of the details of the item addition process in step S210 will be described with reference to the flowchart of FIG.

(Step S604) The classification change unit 17 substitutes the score between the document [i] and the currently associated item into the score on the same axis as the additional item. Here, the score is usually obtained by the same method as the correspondence determination process of FIG.

(Step S605) The classification change unit 17 substitutes the score between the document [i] and the additional item into s.

(Step S606) The classification changing unit 17 proceeds to step S607 if s is larger than score, and proceeds to step S609 if not.

Hereinafter, the specific operation of the technical map output device 1 in the present embodiment will be described.

In this specific example, the document information storage unit 111 stores the document information management table shown in FIG. 7. The document information management table holds records of information about two or more documents. Each record has the attributes of "ID", "document identifier", and "document information". Here, the "ID" existing in the document information management table, the item identifier management table described later, and the document identifier management table is the ID of the record for explanation, and is different from the document identifier and the item identifier.

Further, in this specific example, the item identifier storage unit 112 stores the item identifier management table shown in FIG. The item identifier management table holds records for two or more items on each of the two or more axes. Each record has the attributes of "ID", "axis" and "item identifier".

In this specific example, based on each document of FIG. 7, a technical map having "problems" and "solutions" as axes is output, and an operation when editing the output technical map items will be described.

First, the correspondence determination unit 12 associates each document of FIG. 7 with an item of each axis of a problem / solution means (step S201). In this specific example, a classifier (Random Forest) that outputs the probability of a document containing each item identifier was trained in advance using a corpus. That is, a total of 6 classifiers that output the probability of being a document including each of "power consumption", "manufacturing cost", "workability", "configuration", "material", and "control method" were trained. .. Then, six classifiers are applied to each of the documents of IDs 1 to 6 in FIG. 7 (36 patterns), and the documents are associated with the items that output the highest probabilities in each of the "problem" and the "solution". rice field. As a result, the document identifier management table as shown in FIG. 9 can be obtained. The correspondence determination unit 12 stores the document identifier management table of FIG. 9 in the document identifier storage unit 113.

Next, the technical map configuration unit 13 calculates the radius of the bubble of the technical map based on the document identifier management table of FIG. 9 (step S203). For example, in the case of a bubble located at the intersection of "power consumption" and "control method", the document group {Reference 1, Document 4, Document 5, Document 6} and "Control method" associated with "power consumption" The radius of the bubble is calculated by obtaining the product {Reference 5, Document 6} of the associated document group {Reference 5, Document 6}.

Next, the technology map output unit 14 outputs a technology map (bubble chart) based on the bubble radius calculated by the technology map configuration unit 13 (step S204). As a result, the bubble chart of FIG. 10 is output.

Hereinafter, in this specific example, each operation when an item integration instruction, an item deletion instruction, an item addition instruction, and an item name change instruction are given to the technical map of FIG. 10 will be described.

(Item integration instruction)
For example, suppose that the editing instruction receiving unit 15 receives an instruction to integrate "power consumption" and "manufacturing cost" of the "problem" axis to make it "eco" (steps S204 and S205).

In this case, the axis changing unit 16 integrates the items of ID1 and ID2 in FIG. 8 and newly generates ID7 “eco” (step S206). As a result, the item identifier management table stored in the item identifier storage unit 112 is changed as shown in FIG.

Further, the classification change unit 17 associates all the documents associated with the “power consumption” and the “manufacturing cost” in FIG. 9 with the “eco” (step S206). As a result, the document identifier management table stored in the document identifier storage unit 113 is changed as shown in FIG.

After that, the technical map of FIG. 13 is finally output through the technical map calibration process (step S202) (step S203).

(Item deletion instruction)
Further, for example, it is assumed that the editing instruction receiving unit 15 receives an instruction to delete the "material" of the "solution means" axis (steps S204 and S207).

In this case, first, the classification change unit 17 scans the document associated with the “material” (step S501). As a result, {Reference 3, Document 4} is acquired.

Next, the axis changing unit 16 changes the item identifier storage unit 112 as shown in FIG. 14, in which the ID 5 is deleted from the item identifier management table of FIG.

Next, the classification change unit 17 searches for the item of the "solution" axis that achieves the next highest score after the "material" for each of {References 3 and 4}. As a result, both Document 3 and Document 4 are associated with "configuration" (steps S503 to S506). As a result, the document identifier storage unit 113 is changed as shown in FIG.

After that, the technical map of FIG. 16 is finally output through the technical map calibration process (step S202) (step S203).

(Item addition instruction)
Further, for example, it is assumed that the editing instruction receiving unit 15 receives an instruction to add "power efficiency" to the "problem" axis (steps S204 and S209).

In this case, first, the axis changing unit 16 adds ID 7 “power efficiency” to the item identifier management table of FIG. 8 (step S601). As a result, the item identifier storage unit 112 is changed as shown in the item identifier management table of FIG.

Here, the technical map output device 1 changes the item identifier storage unit 112, and at the same time, collects documents including "power efficiency" from the corpus, and probabilities of including "power efficiency" by using the same method as other items. Learn the classifier that outputs.

Next, the classification change unit 17 checks whether all the documents of ID1 to ID6 in FIG. 7 are associated with "power efficiency" (step S210). Specifically, for each document, the score (step S604) of the item of the "problem" axis currently associated ("power consumption" in the case of Document 1) and the score of "power efficiency" (step S605). ), And when the score of "power efficiency" is higher (step S606), the item currently associated with the document identifier storage unit 113 is deleted (step S607), and then "power efficiency" is displayed. Correspondence (step S608). In the case of this specific example, since the only document associated with "power efficiency" is Document 4, the document identifier storage unit 113 is changed as shown in FIG.

After that, the technical map of FIG. 19 is finally output through the technical map calibration process (step S202) (step S203).

(Item name change instruction)
Further, for example, it is assumed that the editing instruction receiving unit 15 receives an instruction to change the "workability" of the "problem" axis to "usability" (steps S204 and S211).

In this case, the axis changing unit 16 changes the ID3 “workability” of the item identifier management table of FIG. 8 to “usability” (step S212). As a result, the item identifier storage unit 112 is changed as shown in the item identifier management table of FIG. With the change of the item identifier storage unit 112, the document identifier storage unit 113 is also changed as shown in FIG.

After that, the technical map of FIG. 22 is finally output through the technical map calibration process (step S202) (step S203).

As described above, according to the present embodiment, the user can interactively edit the items of the technical map once output.

Further, according to the present embodiment, the technical map output device 1 automatically associates the document with the item even when the user needs to re-associate the document with the item such as deleting the item in editing the technical map. Therefore, the labor of re-association can be saved.

Further, according to the present embodiment, in the technical map output device 1, only the document identifier related to the item edited by the user is changed, so that the portion of the technical map not edited by the user is changed. do not have. Therefore, the technical map is not changed unintentionally by the user, and the user can smoothly edit the technical map.

According to the present embodiment, in the technical map output device 1, in the document identifier storage unit 113, one document identifier may be associated with two or more item identifiers in each axis. In this case, in the correspondence determination process of FIG. 3, step S307 assigns a predetermined score threshold value to score, step S311 associates the document [j] with the item [k], and further, step S313. Is changed to do nothing. Further, in the item deletion process of FIG. 5, step S505 may be changed so as to associate D [i] with items other than the deleted item by using the changed correspondence determination process. Further, in the item addition process of FIG. 6, step S607 is changed so as not to perform anything.

According to the present embodiment, each time the editing instruction receiving unit 15 receives an editing instruction, the correspondence determination process of FIG. 3 may be performed.

Further, the processing in the present embodiment may be realized by software. Then, this software may be distributed by software download or the like. Further, this software may be recorded on a recording medium such as a CD-ROM and disseminated.

The software that realizes the technical map output device in this embodiment is the following program.
