Description

  The present invention relates to an apparatus for performing classification change processing for receiving an item editing instruction and changing a classification according to the editing instruction in a technical map output apparatus that automatically outputs a technical map from a document.

  In order to analyze many technical documents such as patents and papers, a bubble chart as shown in FIG. Such a diagram is called a technology map. This bubble chart is a diagram in which two analysis viewpoints are taken on two vertical and horizontal axes, items are arranged on each axis, and bubbles of a size based on the number of documents related to the items are arranged at the intersections of the items. . For example, it is possible to give an overview of what kind of technology is being developed by creating a technology map centered on “issues” and “solving means” with an analysis object as a patent. The technology map does not necessarily have to be a bubble chart, and may be a diagram in which the number of documents is plotted instead of the bubble in FIG. 25A, and is an intersection of items as shown in FIG. It may be a table in which specific document names are plotted in cells. The technical map may be a three-dimensional bubble chart in which three analysis viewpoints are the X axis, the Y axis, and the Z axis.

  Conventionally, a part in which “issue” or “solution” is described from a technical document (for example, [Effect of invention] for a patent document) is specified, and the contents of the specified part of a plurality of technical documents are specified. There is a system that performs clustering and automatically generates a technical map (see, for example, Patent Document 1).

  On the other hand, there has been an apparatus that interactively classifies documents by reflecting correction of classification results performed by a user in a mechanical document classification method in a tabular technical map (see, for example, Patent Document 2).

(Embodiment 1)
In this embodiment, a patent map output that automatically extracts two or more items of two or more dimension axes from two or more patent documents, constructs axes, classifies patent documents, and outputs a patent map A technical map output apparatus 1 that receives an item editing instruction and performs classification change processing for changing the classification according to the editing instruction in the apparatus will be described.

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

  The technical map output device 1 includes a storage unit 11, a correspondence determination unit 12, a technical map configuration unit 13, a technical map output unit 14, an editing 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 pieces of document information corresponding to a document identifier for identifying a document.

  Here, the document may be anything as long as it can be classified on a technical map such as a patent document or a paper. The patent document may be a patent publication publication, a patent publication publication, or a document at the time of filing a patent, and its format is not limited. In addition to patent documents and papers, for example, product introduction web pages, newspaper articles including product information, company press releases, and 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 determined in the document information storage unit 111. For example, it is preferable to use a patent application number or a patent publication number if the document is an open patent gazette, or a patent number if the document is a patent publication gazette. Further, the structure of the document information corresponding to the document identifier is not limited. 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, a markup language such as HTML may be used to represent the text and its structure, and the document structure may be represented by corner brackets as in a patent document. Further, the document information may include meta information of the document. The meta information is, for example, information related to a document other than text, such as an applicant, an inventor, an agent, an application date, a publication date, IPC, FI, and F-term in a patent document.

  The item identifier storage unit 112 stores item identifiers for identifying two or more items on each axis of two or more dimensions.

  Here, each axis of two or more dimensions is a “viewpoint” that becomes an axis of the technical map. For example, in the case of the two-dimensional technical map of FIG. 25A, “issue” and “solution” 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 shown in FIG. 25A, the items are “strong wind countermeasures” and “lightning strike countermeasures” on the problem axis, and “pitch control” and “variable speed control” on the solution means axis. The item identifier storage unit 112 may include item identifiers of items that are not displayed on the technology 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 “production cost reduction” as the 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 two or more dimensions.

  The document identifier storage unit 113 stores the contents of the technical map (for example, bubble for a bubble chart, the number for a case number map that displays the number of cases instead of bubbles, and the document included in the cell for a table as shown in FIG. 25B). The document identifier of the document corresponding to each item of each dimension is stored. 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 is reflected in the bubble size.

  The correspondence determination unit 12 analyzes each document information of two or more, acquires an item identifier corresponding to each dimension of two or more dimensions for each document information, and sets a document identifier for identifying the document information to each dimension of two or more dimensions. Are 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 for analyzing the document information stored in the document information storage unit 111 and acquiring the item identifier corresponding to the document information in the correspondence determination unit 12. The correspondence determination unit 12 may acquire the item identifier corresponding to each document information with reference to the information in the item identifier storage unit 112, or may refer to the item from the document information without referring to the information in the item identifier storage unit 112. An identifier may be generated.

  When the item identifier corresponding to each document information is acquired by referring to the information in 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. Each stored item identifier is compared, and the correspondence between the document information and the item identifier is determined.

  For example, the number of times an item name (or an item identifier if the item identifier is output as it is in the technology map) appears in the text of each document is calculated, and if that number is equal to or greater 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 the 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. Furthermore, a thesaurus may be used when calculating the number of appearances of the item names and morphemes. Specifically, the name of the item, the broader word or the lower word of the morpheme, or both may be obtained from the thesaurus, and the number of times the word obtained from the thesaurus appears in the text of each document may be used.

  Further, association may be performed using a corpus. For example, for each item stored in the item identifier storage unit 112, the technology map output device 1 collects a document group including the item name (or an item identifier if the item identifier is output to the technology map as it is) from the corpus. Each document included in the document group is converted into a vector, and all of the vectors or a representative vector (for example, an average vector) of the document group is stored in advance. When the correspondence determining 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, document information vector), and the document information vector The similarity may be obtained, and the document identifier may be associated with the item identifier when the similarity is equal to or greater than a predetermined value. Here, as a method of vectorizing a document, a method of vectorizing n-grams (n ≧ 1) of characters and words and other attributes of document information as dimensions, their appearance frequency and TF-IDF as values. Etc. Further, the similarity between the document information vector and the item is a method using a cosine similarity, a Pearson correlation coefficient, a deviation pattern similarity, etc. between the document information vector and an average vector of items stored in advance, It is also possible to obtain the top n vectors that are close to the document information vector among the vector of previously stored items, and calculate the similarity using the distance between the acquired vector and the document information vector (that is, in the vicinity of k Method may be used). In association between the document identifier and the item identifier, the document identifier may be associated with one item having the highest similarity. Note that the vectorization method, the similarity, and the k-nearest neighbor method are well-known techniques, and thus description thereof is omitted.

  Further, for example, as a method of correlating using a corpus, in the corpus, a document including an item name (or an item identifier when the item identifier is output to the technical map as it is) is a correct example, and a document that is not As a negative example, a discriminator for discriminating between a positive example and a negative example may be learned, and a result output from the discriminator may be used as it is (for example, SVM or Random Forest). Further, using the positive example and the negative example, a discriminator (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. It is also possible to apply a classifier to each document, and perform association using a score output from the classifier. 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 performing the association without using the previous corpus, and the score is predetermined. You may match with the item identifier corresponding to all the discriminators which achieve a fixed value or more. Note that the SVM, SVR, and Random Forest are well-known techniques, and thus description thereof is omitted.

  When generating an item identifier from document information without referring to information in the item identifier storage unit 112, the correspondence determination unit 12 generates an item identifier from only each piece of document information stored in the document information storage unit 111. For example, an item identifier can be generated by providing 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 an expression related to each axis from the document information. For example, an important expression related to the “task” axis is an expression such as “can be XX” or “achieves ΔΔ”. The important expression extraction part 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- 540, 2009.) etc. The item aggregating unit has a function of shortening and further collecting the expressions extracted by the important expression extracting unit. For example, the item aggregator shortens the important expression “can reduce resources used” to “resource reduction” and further summarizes “resource reduction” and “reusability improvement” to “recyclability”. . The item aggregator is, for example, the method of Nonaka (Hirofumi Nonaka, Akio Kobayashi, 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 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 technology map configuration unit 13 configures an axis having two or more item identifiers for each axis of two or more dimensions, and uses the document identifier associated with the item identifier of each axis to obtain content information that is the content of the technology map. And configure a technology map having axes and content information.

  Here, the content information is information necessary for outputting the technical map. For example, in the case of the technical map as shown in FIG. 25A, it is information for forming a bubble. Specifically, in the above case, the content information includes at least a bubble radius corresponding to the number of documents. Here, usually, the bubble radius increases in proportion to the number of documents. Further, in the case of the technical map as shown in FIG. 25B, it is a list of documents described in each cell. The content information includes the number of documents in the case of a technical map in which the number of documents included in the bubble is plotted together with the bubble of FIG. 25A or instead of the bubble. Furthermore, if a bar graph is plotted instead of bubbles, it is information constituting the bar graph. Usually, the information constituting the bar graph includes the height of the bar graph. In general, the height of the bar graph increases in proportion to the size of the number of documents. As described above, the content information requires different information depending on the form of the technology map to be output.

  The technical map configuration unit 13 reconfigures 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 technology map construction unit 13 is content information adapted to the form of the technology 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. Configure.

  The technical map output unit 14 outputs a technical map. The method for outputting the technology map from the content information configured by the technology map configuration unit 15 is a known technology and will not be described.

  Here, output refers to display on a display, projection using a projector, printing on a printer, transmission to an external device, storage in a recording medium, processing result to another processing device or other program, etc. It is a concept that includes delivery.

  When the technology map composition unit 13 reconstructs the content information, the technology map output unit 14 re-outputs the technology map based on the reconstructed content information.

  The edit instruction accepting unit 15 accepts an edit instruction that is an instruction to edit an axis item included in the technical map output from the technical map output unit 14.

  The edit instruction is, for example, an item integration instruction to make two or more items into one item, an item deletion instruction to delete at least one item, an item addition instruction to add an item, an item name change instruction to change an item name It 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 an item integration instruction, the axis changing unit 16 changes two or more item identifiers to one item identifier according to the item integration instruction. For example, when the item integration instruction includes two or more item identifiers (hereinafter referred to as integration source item identifiers) that are integration sources and one item identifier that is an integration destination (hereinafter referred to as integration destination item identifier), the axis changing 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. When the item integration instruction includes only the integration source item identifier, the axis changing unit 16 may automatically generate an integration destination item identifier from the integration source item identifier. For example, the axis changing unit 16 may connect the integration source item identifiers with a predetermined connection character string (for example, “·”) and use the connected identifiers as integration destination item identifiers. In addition, for example, the axis changing unit 16 may acquire or generate a broader term of the integration source item identifier using a thesaurus, and use it as the integration destination item identifier.

  In addition, when the editing instruction receiving unit 15 receives an 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 by the item deletion instruction from the item identifier storage unit 112.

  In addition, when the editing instruction receiving unit 15 receives an item addition instruction, the axis changing unit 16 adds an item identifier for identifying an item corresponding to the item adding instruction to the item identifier storage unit 112. For example, the axis changing unit 16 adds the item identifier designated by the item addition instruction to the item identifier storage unit 112.

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

  The classification changing unit 17 changes the correspondence of the document identifier related to the item corresponding to the editing instruction among the one or more document identifiers in 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 editing instruction received by the editing 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 editing instruction, the document identifier associated with the currently associated document identifier, 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 a document identifier related to 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 includes, for example, all document identifiers associated with two or more item identifiers to be integrated specified in the item integration instruction. Are deleted from the document identifier storage unit 113, and then all the document identifiers are associated with the item identifiers of the integration destination. Further, for example, the classification changing unit 17 deletes all of the document identifiers associated with the two or more item identifiers to be integrated instructed by the eye integration instruction from the document identifier storage unit 113, and then deletes the document information storage unit For all the document information stored in 111, the document identifier corresponding to the item identifier of the integration destination may be determined using the same method as the correspondence determination unit 12.

  When the editing instruction received by the editing instruction receiving unit 15 is an item deletion instruction, the classification changing unit 17 uses, for example, a document identifier associated with an item identifier corresponding to the item deletion instruction (hereinafter referred to as a deletion target item identifier) as a document identifier. Delete from the storage unit 113. Further, for example, the classification changing unit 17 deletes the document identifier from the document identifier storage unit 113 and then deletes the document identifier associated with the item identifier to be deleted or all document identifiers stored in the document information storage unit 111. The document determination method may be associated with an item identifier other than the deletion target item identifier 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, for example, for the document identifiers corresponding to all the document information stored in the document information storage unit 111, Using the same method, association with the added item identifier is performed. Here, when the correspondence determining unit 12 associates one item identifier with one document identifier, the correspondence between the added item identifier and an item identifier other than the added item identifier is the document. Delete 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 the item name changing instruction stored in the item identifier storage unit 112 and the document identifier storage unit 113, for example. 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 of storing information in the storage unit 11, the document information storage unit 111, the item identifier storage unit 112, and the document identifier storage unit 113 is not limited. For example, 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 a recording medium, and 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 information input via an input device may be stored in the storage unit 11, The information 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 be usually realized by an MPU, a memory, or the like. The processing procedures of the correspondence determination unit 12, the technical map configuration unit 13, the axis change unit 16, and the classification change unit 17 are usually realized by software, and the software is recorded on a recording medium such as a ROM. However, it may be realized by hardware (dedicated circuit).

  The technical map output unit 14 may or may not include an output device such as a display. The technology map output unit 14 can be realized by output device driver software, or output device driver software and an output device.

  The editing instruction receiving unit 15 can be realized by a device driver of an input means such as a mouse or a touch panel, control software for a menu screen, or the like.

  Next, the operation of the technical map output device 1 will be described using the flowchart of FIG. Hereinafter, the i-th information in the predetermined information is referred to as “information [i]”.

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

  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. The item deletion instruction includes one item identifier to be deleted. The item addition instruction includes one item identifier to be added. The item name change instruction includes one item identifier to be changed and an item identifier after the change (that is, the item identifier before the change and the item identifier after the item identifier is changed).

  In the present embodiment, the technical map output device 1 is configured to integrate the document identifiers associated with two or more item identifiers to be integrated when the item integration instruction is instructed. Corresponds to the item identifier. In addition, when an item deletion instruction is instructed, the technical map output device 1 associates the document identifier associated with the item identifier to be deleted with one item identifier other than the item identifier to be deleted. In addition, when an instruction to add an item is given, the technology map output device 1 associates all 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 correspondence 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 designated. It is associated with the item identifier (item identifier to be added).

  (Step S <b> 201) 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 accumulates information in the document identifier storage unit 113. Such a process is called a correspondence determination process. Details of the correspondence determination process will be described with reference to the flowchart of FIG.

  (Step S202) The technical map construction unit 13 constructs content information necessary for outputting a technical map based on the information stored in the document identifier storage unit 113. Such a process is called a technology map construction process. Details of the technology map construction processing will be described with reference to the flowchart of FIG.

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

  (Step S309) The correspondence determining unit 12 substitutes the score between the document [j] and the item [k] for the variable s. Here, the score is a score representing the likelihood that the document [j] belongs to the item [k], and if the value is larger, the score represents that the document [j] belongs to the item [k]. Any value may be used. A specific method for calculating the score will be described later.

  (Step S310) The correspondence determining unit 12 proceeds to step S311 if s obtained in step S309 is larger than score, and proceeds to step S312 otherwise.

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

  (Step S314) The correspondence determining unit 12 increments 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 document and the item are “corresponding” as the value increases.

  For example, the number of times a character string representing an item (in this embodiment, an item identifier) appears in a document may be used as a score. Further, the character string representing the item may be subjected to morphological analysis, and the total number of times each morpheme appears may be used as a score.

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

  (Step S405) The technical map construction unit 13 acquires all the documents associated with both the item [i] and the item “j” and substitutes them for D.

  (Step S406) The technical map construction unit 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 construction unit 13 increments i by 1 and returns to step S402.

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

  (Step S505) The classification changing unit 17 associates the document [i] with the item that achieves the highest score, and accumulates it in the document identifier storage unit 113. This step is normally associated with the item having the highest score by the same processing as in steps S307 to S313 of the correspondence determination processing in 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 increments the counter i by 1, and returns to step S504.

  (Step S604) The classification changing unit 17 substitutes the score between the document [i] and the item currently associated with the score on the same axis as the additional item. Here, the method of obtaining the score normally uses the same method as the correspondence determination process in FIG.

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

  (Step S606) The classification changing unit 17 proceeds to step S607 when s is larger than score, and proceeds to step S609 otherwise.

  (Step S609) The classification changing unit 17 increments the counter i by 1, and returns to step S603.

  Hereinafter, a 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. The document information management table holds records of information regarding two or more documents. Each record has attributes of “ID”, “document identifier”, and “document information”. Here, “ID” existing in the document information management table, the item identifier management table, and the document identifier management table, which will be described later, is an ID of a record for explanation, and is different from the document identifier and the item identifier.

  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 relating to two or more items on each of two or more axes. Each record has attributes of “ID”, “axis”, and “item identifier”.

  In this specific example, a description will be given of an operation when a technical map having “issue” and “solving means” as axes is output based on each document shown in FIG. 7 and items of the output technical map are edited.

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

  Next, the technology map construction unit 13 calculates the radius of the technology map bubble 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, Reference 4, Reference 5, Reference 6} associated with “Power consumption” and “Control method” The radius of the bubble is calculated by obtaining a collection {document 5, document 6} of the associated document group {document 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 performed on the technology map of FIG. 10 will be described.

(Item integration instructions)
For example, it is assumed that the editing instruction receiving unit 15 receives an instruction to integrate “power consumption” and “manufacturing cost” on the “issue” axis to make “eco” (steps S204 and S205).

  In this case, the axis changing unit 16 integrates the items ID1 and ID2 of 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 changing unit 17 associates all the documents associated with “power consumption” and “manufacturing cost” in FIG. 9 with “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.

  Thereafter, a technical map shown in FIG. 13 is finally output through a technical map calibration process (step S202) (step S203).

(Item deletion instruction)
For example, it is assumed that the editing instruction receiving unit 15 receives an instruction to delete the “material” on the “solution means” axis (steps S204 and S207).

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

  Next, the axis changing unit 16 changes the item identifier storage unit 112 as shown in FIG. 14 in which ID5 is deleted from the item identifier management table of FIG.

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

  Thereafter, a technical map shown in FIG. 16 is finally output through a technical map calibration process (step S202) (step S203).

(Item addition instructions)
For example, it is assumed that the editing instruction receiving unit 15 receives an instruction to add “power efficiency” to the “task” axis (steps S204 and S209).

  In this case, first, the axis changing unit 16 adds ID7 “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 technology map output device 1 changes the item identifier storage unit 112 and simultaneously collects documents including “power efficiency” from the corpus, and uses the same method as other items to calculate the probability of including “power efficiency”. Is learned.

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

  Thereafter, the technical map shown in FIG. 19 is finally output through the technical map calibration process (step S202) (step S203).

(Item name change instruction)
For example, it is assumed that the editing instruction receiving unit 15 receives an instruction to change “workability” of the “task” axis to “usability” (steps S204 and S211).

  In this case, the axis changing unit 16 changes ID3 “workability” in 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.

  Thereafter, the technical map shown in 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 technology map once output.

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

  Further, according to the present embodiment, since only the document identifier related to the item edited by the user is changed, the technical map output device 1 is changed in the part of the technical map that is not edited by the user. Absent. Therefore, a technical map change that is not intended by the user does not occur, and the user can edit the technical map smoothly.

  According to the present embodiment, the technical map output device 1 may associate one document identifier with two or more item identifiers in each axis in the document identifier storage unit 113. In this case, in the correspondence determination process of FIG. 3, step S307 assigns a predetermined score threshold to score, step S311 associates document [j] with item [k], and step S313. Is changed to do nothing. Furthermore, in the item deletion process of FIG. 5, step S505 may be changed so that D [i] is associated with other than the deleted item using the changed correspondence determination process. Furthermore, in the item addition process of FIG. 6, step S607 is changed so that nothing is performed.

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

  Furthermore, 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 and distributed on a recording medium such as a CD-ROM.
