Description

  The present invention relates to an idea support apparatus, an idea support system, an idea support program, and an idea support method for presenting an idea support word for expanding, for example, a conversation, a keyword appearing in a document, or an idea.

  In recent years, for example, companies are required to become “enterprises that can create new value based on knowledge”.

  For this purpose, companies are engaged in intellectual production activities such as changing a combination of existing knowledge into creativity or creating new ideas with information obtained from outside (external).

  Further, for example, in a meeting (conference space) in a company, it is required to create new value that cannot be obtained by an individual (independent) for a plurality of participants who participate in (attend) the meeting. However, it is not easy to create new value even by a plurality of conference participants.

  In order to promote the creation of new value as described above, it is necessary to activate a “place (Ba)” called a conference space. For this reason, for example, it is necessary to support the smooth communication performed in the conference space. Therefore, for example, in a conference space, it is conceivable to create a new effect by adding not only “people and people” but also “people and IT”.

As a technique related to this, for example, a technique for searching and maintaining a Web page appropriate for the conversation content between humans is disclosed (for example, see Patent Document 1). According to this technology, it is possible to accurately understand a conversation between humans using an ontology, and to search for an appropriate web page using the ontology and meta information.
JP 2004-341672 A

  As described above, for example, in a conference, the contents of the conference are shared by all the participants to understand, and by expanding the idea that cannot be expanded only by the participants of the conference, the “space (Ba)” of the conference space. Need to be activated.

  For example, assume that there is a participant who does not understand the content of the conference in the conference, that is, the conference content cannot be shared by all the participants. In this case, generally, for example, by writing the content discussed in the conference on, for example, a whiteboard, all the participants can understand the content of the conference. Participants who do not understand the contents of the meeting, for example, ask the other participants of the meeting about the contents of the meeting, or investigate the contents that they do not understand, for example, using the Internet etc. The contents can be understood.

  However, for example, when the content being discussed at the conference is written on the whiteboard, the conference may be temporarily suspended or delayed while the whiteboard is being written. In addition, when a participant who does not understand the content of the conference asks other participants about the content that cannot be understood by other participants, the participation of the other participants in the conference may be temporarily interrupted. In addition, while a participant who does not understand the content of the conference is investigating the content of the conference, the participant cannot concentrate on the conference.

  In addition, for example, a case is assumed in which there is information related to the content of the conference concerned by the participants of the conference. In this case, for example, the participant can obtain knowledge about the information by speaking about information related to the contents of the conference and listening to other participants on the spot. In addition, a participant who is concerned about information related to the content of the conference can obtain knowledge about the information by investigating the information by himself / herself.

  However, for example, if a participant asks another participant on the spot for information related to the content of the conference, the other participant's participation in the conference may be temporarily interrupted, and the conference itself may be removed from the subject. Conceivable. In addition, when investigating information related to the content of the conference by himself, the investigating participant cannot concentrate on the conference.

  In general, it is not easy for a conference participant alone to expand creative ideas. For example, assigning a new participant or searching the Internet or other materials to obtain new information can be considered. However, when assigning a new participant, it may be possible to constrain the time of the new participant. In addition, for example, when searching the Internet or other materials, it is difficult to obtain useful information because the search method and the target range are limited.

  An object of the present invention is to provide an idea support device that activates a conference space by, for example, presenting an idea support word for expanding keywords or ideas that appear in conversations or materials in a conference to the participants of the conference. To provide a support system, an idea support program, and an idea support method.

Context-forming word set extraction means and a first relation indicating a ratio of words stored in the analysis result storage means appearing in proximity to words constituting the extracted first context-forming word set A first relevance calculating means for calculating the first relevance, a first keyword extracting means for extracting a first keyword based on the calculated first relevance, and the extracted first context forming word Included in the character string by analyzing the character string included in the retrieved information and information retrieval means for retrieving information including the character string including the words constituting the set from external information sources A set of words that appear close to each other in the character string analyzed by the second analysis means, out of the words extracted by the second analysis means and the second analysis means The second context forming word set extracting means for extracting the second context forming word set and the words extracted by the second analyzing means become the words constituting the extracted second context forming word set. Near Second relevance calculation means for calculating a second relevance level indicating the ratio of appearance, and second keyword extraction means for extracting a second keyword based on the calculated second relevance ratio And a presentation unit for presenting the extracted first keyword and the extracted second keyword.

  According to the present invention, it is possible to activate a conference space by, for example, presenting an idea support word for expanding keywords or ideas that appear in conversations or materials in a conference to the participants of the conference. .

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing an outline of an idea support system according to an embodiment of the present invention. This idea support system is applied, for example, in a meeting (conference space) in a company or the like.

  As shown in FIG. 1, the idea support system includes an audio recording device 1, an idea support device (server) 2, and a display device (output device) 3.

  The audio recording device 1 is a device that records audio such as a microphone. The voice recording device 1 records the conversation (voice) of participants during the conference, for example, at a conference. The voice recorded by the voice recording device 1 is sent to the idea support device 2.

  The idea support device 2 extracts, for example, a keyword representing the content of the conference (conversation content of the conference participants) or an idea support word for expanding the idea in the conference based on the voice sent from the audio recording device 1. Execute the process.

  The display device 3 is, for example, a display, and displays, for example, keywords or idea support words extracted by the idea support device 2 to the conference participants. The display device 3 may be an output device such as a printer. In this case, for example, a page on which the keyword or the idea support word extracted by the idea support device 2 is printed is presented to the conference participants.

  In the conference space, for example, a configuration in which a material reading device 4 as shown in FIG. 2 is provided may be used. The material reading device 4 includes a projection unit 4a and a material image reading unit 4b.

  The projection unit 4a projects conference materials by a projector, for example. The conference material is, for example, electronic media material including character strings.

  The document image reading unit 4b is, for example, a digital camera that photographs the conference material projected on the projection unit 4a at regular intervals. The image (data) of the conference material photographed by the material image reading unit 4 b is sent to the idea support device 2.

  When the image data of the conference material is sent from the material reading device 4, the idea generation support device 2 based on the image data, as described above, the keyword representing the conference content (conversation content of the conference participants) or the conference data Extract idea support words to expand ideas.

  Note that the idea support device 2 may be configured to capture image data directly from, for example, a projector that projects conference materials, a plasma display, or other devices connected thereto.

  FIG. 3 is a block diagram showing a hardware configuration of the idea support apparatus 2 shown in FIG. As shown in FIG. 3, the computer 5 is connected to an external storage device 10 such as a hard disk drive (HDD). The external storage device 10 stores a program 11 executed by the computer 5. The computer 5 and the external storage device 10 constitute an idea support device 2.

  FIG. 4 is a block diagram mainly showing a functional configuration of the idea support device 2. The idea support device 2 includes an input reception unit 21, a calculation unit 22, and a display control unit 23. In this embodiment, each part 21 thru | or 23 shall be implement | achieved when the computer 5 shown by FIG. 3 runs the program 11 stored in the external storage device 10. FIG. This program 11 can be stored in advance in a computer-readable storage medium and distributed. Further, this program 11 may be downloaded to the computer 10 via, for example, a network.

  The idea support device 2 includes a storage (storage) unit 12. In the present embodiment, the storage unit 12 is stored in the external storage device 10.

  The input receiving unit 21 inputs sound (data) recorded by the sound recording device 1. The input receiving unit 21 inputs image data of, for example, conference material read by the material reading device 4 (hereinafter referred to as material image). This meeting material includes a character string.

  The computing unit 22 executes various processes based on the voice and the material image input by the input receiving unit 21. The calculation unit 22 includes a text analysis unit 221, a context forming word set extraction unit 222, a keyword extraction unit 223, and an Internet search unit 224.

  The text analysis unit 221 acquires the voice input by the input reception unit 21. The text analysis unit 221 converts (converts) the acquired speech into a character string including a word, for example, by speech recognition processing. The converted character string is composed of a sentence including a word, for example.

  The text analysis unit 221 acquires the material image input by the input reception unit 21. The text analysis unit 221 extracts (converts to text) a character string included in the material based on the obtained material image. At this time, the text analysis unit 221 converts the material image into text using, for example, OCR (Optical Character Recognition).

  The text analysis unit 221 performs a morphological analysis process on a character string converted from speech and a character string extracted from a material image (hereinafter collectively referred to as a character string). Here, the morpheme analysis process is an operation (process) for dividing a sentence written in a natural language, for example, into morphemes (the smallest unit having meaning in the language) and determining each part of speech.

  Further, the text analysis unit 221 executes a morphological analysis process on a character string included in information (site) searched by the Internet search unit 224, for example. This character string is composed of a sentence including a word, for example.

  The text analysis unit 221 extracts (acquires) words (word series) included in the character string based on the morphological analysis result. At this time, the text analysis unit 221 creates compound nouns by connecting nouns that appear (appear) continuously among the extracted words, for example. When a compound noun is created, the text analysis unit 221 replaces the compound noun and the word used to create the compound noun. Further, the text analysis unit 221 replaces, for example, an indicator in the extracted word with an antecedent (word) corresponding to the indicator.

  The text analysis unit 221 excludes, for example, particles, adverbs, suffixes (suffixes) and the like from the extracted words. The text analysis unit 221 stores, in the storage unit 12, words (for example, nouns, adjectives, adjective verbs, verbs, and compound nouns) from which extracted particles, for example, particles, adverbs, suffixes, and the like are excluded. . At this time, for example, information indicating the order of appearance of words in the character string subjected to morphological analysis and the sentence in which the word appears (included) is also stored in the storage unit 12.

  The context-forming word set extraction unit 222 acquires words (for example, word sequences and compound nouns such as nouns, adjectives, adjective verbs, and verbs) stored in the storage unit 12. The context-forming word set extraction unit 222 arranges the acquired words in the order of the number of appearances. The context forming word set extraction unit 222 acquires the top n (n is a value defined in advance) words in the order of appearance frequency among the acquired words.

  The context-forming word set extraction unit 222 extracts a context-forming word set from the acquired top n words using, for example, a lexical linkage hypothesis technique. This lexical linkage hypothesis is a hypothesis that vocabulary appearing in a string (text) is semantically related. The context-forming word set represents, for example, a basic concept necessary for sharing the topic of the conference (for example, the base of the topic or the background of the topic).

  The context-forming word set extraction unit 222 is a context-forming word set that is a set of words that appear close to each other (positioned in the vicinity) in the character string subjected to morphological analysis, among the acquired top n words. To extract. At this time, the context-forming word set extraction unit 222 extracts a context-forming word set based on the number of times the acquired top n words appear in, for example, a sentence constituting a character string subjected to morphological analysis. Details of the context-forming word set extraction process will be described later.

  The keyword extraction unit 223 acquires words stored in the storage unit 12. The keyword extraction unit 223 has a ratio in which the acquired word appears close to (is located in the vicinity of) a word (context formation word) constituting the context formation word set extracted by the context formation word set extraction unit 222 ( The degree of association indicating the probability is calculated. Details of this relevance calculation processing will be described later.

  The keyword extraction unit 223 extracts keywords based on the calculated degree of association. The keyword extracted by the keyword extraction unit 223 is, for example, a part that is particularly emphasized as important information in a meeting, that is, a word representing an argument of discussion in the meeting.

  For example, the keyword extraction unit 223 arranges the words acquired from the storage unit 12 in the order of the calculated relevance. Here, the keyword extraction unit 223 selects, for example, a noun and a compound noun from each of the words arranged in the order of relevance. The keyword extraction unit 223 extracts, from the selected nouns and compound nouns, the top n (n is a predefined value) words as keywords in order of relevance. The keyword extracted by the keyword extraction unit 223 is, for example, a part that is particularly emphasized as important information in a meeting, that is, a word that represents an argument of discussion in the meeting.

  Note that the keyword extraction unit 223 may be configured to extract, as keywords, words whose calculated relevance is equal to or greater than a predetermined value.

  The storage unit 12 holds, for example, a search expression format used for creating a search expression for searching for meaning contents of a word from information (for example, a site) holding (including) the meaning contents of the word. Stores a semantic content search list. In addition, the storage unit 12 stores a site configuration list that holds configuration information indicating the configuration of a site including the meaning content of words, for example. Further, the storage unit 12 stores, for example, rules for displaying the above-described context-forming word set or keywords (rule information indicating the rules).

  The Internet search unit 224 uses a search expression format stored in the semantic content search list stored in the storage unit 12 as a search expression for searching for the semantic content of the keyword extracted by the keyword extraction unit 223. create. The Internet search unit 224 searches the semantic content of the acquired keyword, for example, using the created search expression. The Internet search unit 224 searches the meaning content of a keyword from an information source that exists outside the idea support system (for example, exists on the Internet), for example.

  The Internet search unit 224 identifies the (display) position of the character string or image representing the semantic content of the keyword in the searched site based on the configuration information held in the site configuration list stored in the storage unit 12 (get. The Internet search unit 224 cuts out a character string or an image at the specified position.

  Further, the Internet search unit 224 creates a search formula based on the context formation word set extracted by the context formation word set extraction unit 222. This search expression is used to search for information (for example, a site or a document) including a context-forming word set (a character string including words constituting the context). Details of the processing for creating this search expression will be described later.

  The internet search unit 224 uses the created search formula to search for sites including, for example, words (a character string including the words) constituting the context forming word set.

  For example, the Internet search unit 224 extracts (acquires) an idea support word for expanding (supporting) an idea that is not spread only by participants in the conference from the searched site (a character string included in the searched site). Details of the process of extracting the idea support word will be described later.

  The display control unit 23 causes the display device 3 to output (display) the context formation word set extracted by the context formation word set extraction unit 222 or the keyword extracted by the keyword extraction unit 223, for example. Thereby, the display control unit 23 presents the context forming word set or the keyword to, for example, the conference participant. In addition, the display control unit 23 presents the idea support word extracted (searched) by the Internet search unit 224 to, for example, a conference participant. At this time, the display control unit 23 forms a context based on the rules indicated by the rule information stored in the storage unit 12 or the appearance order (information indicating) of the words stored in the storage unit 12. A word set, a keyword, or an idea support word is displayed on the display device 3. Details of the rule information stored in the storage unit 12 will be described later.

  FIG. 5 shows an example of the data structure of the storage unit 12 included in the idea support device 2. As shown in FIG. 5, the storage unit 12 stores a semantic content search list, a site configuration list, and rule information.

  The semantic content search list holds dictionary information indicating sites (dictionary sites) that hold the semantic content of keywords extracted by the keyword extraction unit 223, for example. This dictionary information includes, for example, a search expression format used for creating a search expression for searching the semantic content of a keyword.

  The site configuration list holds configuration information indicating the configuration of a site having the meaning content of the keyword extracted by the keyword extraction unit 223, for example.

  The rule information includes, for example, the context-forming word set extracted by the context-forming word set extraction unit 222, the keyword extracted by the keyword extraction unit 223, the semantic content of the keyword searched by the Internet search unit 224, or the Internet search unit 224. The rule at the time of displaying the extracted idea support word on the display apparatus 3 is shown.

  FIG. 6 shows an example of the data structure of the semantic content search list stored in the storage unit 12. As shown in FIG. 6, the semantic content search list holds, for example, dictionary information indicating sites (dictionary sites) for searching the semantic content of keywords. The dictionary information includes, for example, a search order indicating the order in which the semantic content of the keyword is searched, the site name of the site where the semantic content of the keyword is searched, the URL (Uniform Resource Locator) of the site, and the meaning of the keyword in the site A search expression format used for creating a search expression for searching the contents is stored in association with each other.

  In the example shown in FIG. 6, the dictionary information 111 includes, for example, a search order “1”, a site name “AAA Encyclopedia”, a URL “http://en.aaa.org/”, and a search expression format “http: // en .aaa.org // search = "search term" "included. In this case, for example, by creating a search formula by applying a keyword to a search term in the search formula format, the semantic content of the keyword can be searched on the site “AAA Encyclopedia”.

  The dictionary information 112 includes, for example, a search order “2”, a site name “BBB dictionary”, a URL “http://www.bbb.jp/”, and a search expression format “http://www.bbb.jp/content/query”. = "Search term" "is included. In this case, for example, by creating a search formula by applying a keyword to a search term in the search formula format, the semantic content of the keyword can be searched in the site “BBB dictionary”.

  The dictionary information 113 includes, for example, a search order “3”, a site name “CCC dictionary”, a URL “http://dictionary.ccc.ne.jp/”, and a search expression format “http://dictionary.ccc.ne”. .jp / search = “search term” ”is stored in association with each other. In this case, for example, by creating a search formula by applying a keyword to a search term in the search formula format, the semantic content of the keyword can be searched in the site “CCC dictionary”.

  FIG. 7 shows an example of the data structure of the site configuration list stored in the storage unit 12. As shown in FIG. 7, in the site configuration list, for example, site configuration information specified by a site name or URL (included in the dictionary information) held in the semantic content search list stored in the storage unit 12 Is held. The configuration information includes, for example, a search order indicating the order in which the semantic content of a keyword is searched, the site name of the site from which the semantic content of the keyword is searched, and the position (meaning of a character string indicating the semantic content of the keyword on the site Content display section) and the position of the image representing the semantic content of the keyword on the site (image display section).

  That is, the configuration information held in the site configuration list indicates the configuration of the site specified by the site name or URL held in the semantic content search list in association with the search order included in the configuration information.

  In the example shown in FIG. 7, the configuration information 121 includes a search order “1”, a site name “AAA Encyclopedia”, a meaning content display section “in the <p> tag before the table of contents”, and an image display section “under the search term”. In the <image> tag displayed in (next). In this case, for example, as the meaning content of the keyword, a character string described in “in the <p> tag before the table of contents” in the “AAA Encyclopedia” site and “<image> displayed immediately below the search term” The “inside tag” image is cut out.

  The configuration information 122 includes the search order “2”, the site name “BBB dictionary”, the meaning content display section “<p> inside the tag displayed immediately below the search word (next)” and the image display section “directly below the search word (next ) In the <image> tag displayed in In this case, for example, as the meaning content of the keyword, a character string described in “in the <p> tag displayed immediately below the search word” in the “BBB dictionary” site and “displayed immediately below the search word < The image in “image> tag” is cut out.

  The configuration information 123 includes a search order “3”, a site name “CCC dictionary”, a meaning content display section “inside <p> tag displayed immediately below (next)” and an image display section “none”. In this case, for example, a character string described in “in the <p> tag displayed immediately below the search word” in the “CCC dictionary” site is extracted as the semantic content of the keyword.

  Next, the processing procedure of the idea support device 2 will be described with reference to the flowchart of FIG.

  First, the input receiving unit 21 included in the idea support device 2 receives input of various data (step S1). Specifically, the input receiving unit 21 inputs sound recorded by the sound recording device 1. Moreover, the input reception part 21 inputs the image (material image) of the material read by the material reading device 4, for example. This material includes, for example, a character string.

  Next, the text analysis unit 221 included in the calculation unit 22 performs text analysis processing (step S2). The text analysis unit 221 converts the voice input by the input reception unit 21 into a character string including, for example, a word by voice recognition processing. Further, the text analysis unit 221 extracts a character string included in the material based on the material image input by the input receiving unit 21. In this case, the text analysis unit 221 extracts a character string from the material image using, for example, OCR.

  The text analysis unit 221 performs morphological analysis on a character string converted from speech or a character string (text) extracted from a material image. Thereby, the text analysis part 221 extracts the word contained in a character string. The text analysis unit 221 stores the extracted word in the storage unit 12. At this time, the text analysis unit 221 stores, for example, information indicating the order of appearance of words and a sentence in which the word appears in the storage unit 12.

  The context-forming word set extraction unit 222 executes, for example, a process of extracting a context-forming word set that represents a basic concept necessary for sharing the topic of the conference (step S3). The context forming word set extraction unit 222 acquires words stored in the storage unit 12. The context-forming word set extraction unit 222 extracts a context-forming word set that is a set of words that appear close to each other in the character string analyzed by the text analysis unit 221 from the acquired words. At this time, the context forming word set extraction unit 222 performs extraction based on the number of times the acquired word appears in a sentence included in a character string subjected to morphological analysis processing by the text analysis unit 221, for example.

  Next, the keyword extraction unit 223 executes, for example, a keyword extraction process that is a word representing a discussion argument in a meeting. The keyword extraction unit 223 indicates the degree of association (probability) that indicates that the words stored in the storage unit 12 appear close to the words constituting the context formation word set extracted by the context formation word set extraction unit 222. Is calculated. The keyword extraction unit 223 extracts keywords from the words stored in the storage unit 12 based on the calculated degree of association (step S4).

  The display control unit 23 displays (outputs) the context forming word set extracted by the context forming word set extracting unit 222 and the keyword extracted by the keyword extracting unit 223 by, for example, the display device (output device) 3, for example, Presented to the conference participants (step S5). The display control unit 23 executes the presentation process based on, for example, the rule information stored in the storage unit 12 or the appearance order of words. By confirming the presented context-forming word set and keywords, for example, a conference participant can understand (confirm) the current conversation (discussion) content and the like.

  The Internet search unit 224 executes a keyword semantic content search process extracted by the keyword extraction unit 223 (step S6). The Internet search unit 224 refers to, for example, the semantic content search list and the site configuration list stored in the storage unit 12 and uses the keyword content extracted by the keyword extraction unit 223 as an information source existing on the Internet, for example. Search from (for example, site).

  Next, the Internet search unit 224 executes, for example, a search (extraction) process of an idea support word for expanding the idea of a conference participant (step S7). Based on the context formation word set extracted by the context formation word set extraction unit 222, the Internet search unit 224 searches for information including the context formation word set (words constituting the context formation word set) via the Internet, for example. The information searched by the Internet search unit 224 includes a character string composed of a sentence including a word, for example. The Internet search unit 224 extracts an idea support word from words included in the searched information.

  The display control unit 23 causes the display device 3 to display the semantic content of the keyword extracted by the keyword extraction unit 223 searched by the Internet search unit 224, for example. In addition, the display control unit 23 causes the display device 3 to display the idea support word extracted by the Internet search unit 224 as, for example, the next conversation candidate in the conference (step S8). The display control unit 23 performs processing based on, for example, rule information stored in the storage unit 12 or appearance order of words. In this way, by displaying the idea support word on the display device 3, it is possible to support, for example, an idea that does not spread in the conference for participants of the conference.

  Here, the context forming word set and the keyword are displayed in step S5, and the semantic content of the keyword and the idea support word are displayed in step S8. However, for example, even in a configuration in which they are collectively displayed in step S8. I do not care. These display timings can be changed as appropriate.

  Next, with reference to the flowchart of FIG. 9, the processing procedure of the text analysis process by the text analysis part 221 is demonstrated in detail.

  First, the text analysis unit 221 acquires the voice (conversation during a meeting) input by the input reception unit 21 (step S11). This sound is recorded, for example, by the sound recording device 1 provided outside the idea support device 2.

  The text analysis unit 221 converts (converts) the acquired voice into a character string (first character string) by voice recognition processing (step S12). The converted character string is composed of a sentence including a word (first word).

  Next, the text analysis unit 221 determines whether or not a material including a character string is used in a meeting, for example (step S13).

  When it is determined that the material is used (YES in step S13), the text analysis unit 221 extracts a character string (text) included in the material (step S14).

  The text analysis unit 221 performs morphological analysis on the character string converted from the voice and the character string extracted from the material used in the conference (step S15). The text analysis unit 221 extracts words included in the character string by performing morphological analysis on the character string.

  The text analysis unit 221 creates a compound noun by connecting, for example, consecutively appearing nouns among the extracted words (step S16). In this case, the text analysis unit 221 replaces the word (noun) used to create the compound noun with the compound noun.

  In addition, the text analysis unit 221 replaces the indicator in the extracted word with a word corresponding to the indicator (step S17).

  The text analysis unit 221 excludes particles, adverbs, suffixes, and the like from words extracted by morphological analysis and stores (saves) them in the storage unit 12 (step S18). That is, the text analysis unit 221 stores, for example, nouns, adjectives, adjective verbs, verbs, and compound nouns in the storage unit 12 among the extracted words. At this time, the text analysis unit 221 stores in the storage unit 12 information indicating the appearance order of words stored in the storage unit 12 and the sentence in which the word appears.

  On the other hand, if it is determined in step S13 that the material is not used, the process of step S15 is executed. In this case, in step S15, the morphological analysis process is executed only for the character string converted from the speech.

  Here, with reference to the flowchart of FIG. 10, the above-described processing of step S <b> 12 of FIG. 9 (material use determination processing) will be described in detail.

  The text analysis unit 221 acquires the material image input by the input reception unit 21 (step S21). This material image is read by, for example, the material reading device 4 as shown in FIG. The material image is image data obtained by photographing the material content projected on the projection unit 4a of the material reading device 4 by a projector or the like, for example, by a material image reading unit 4b such as a digital camera. Note that the document image reading unit 4b photographs the projection unit 4a, for example, at regular intervals. Images taken at regular intervals are sent to the idea support device 2 as document images.

  The text analysis unit 221 extracts (converts to text) a character string included in the acquired document image (captured image) (step S22). At this time, the text analysis unit 221 executes text processing using OCR.

  Here, the text analysis unit 221 determines whether the character string has been extracted, that is, whether the text (information) has been acquired (step S23).

  For example, assume that materials are used in a meeting. In this case, for example, the material content is projected on the projection unit 4 a of the material reading device 4. When the text analysis unit 221 converts an image (material image) obtained by photographing the projection unit 4a (material content projected onto the projection unit 4a) into a text, a character string included in the material content is extracted. That is, in this case, the text analysis unit 221 determines that the character string has been extracted.

  When it is determined that the character string has been extracted (YES in step S23), the text analysis unit 221 assumes that the material content is projected (displayed) on the projection unit 4a as described above, and the material is used in the meeting. (Step S24).

  On the other hand, for example, a case where materials are not used in a meeting is assumed. In this case, for example, the material content is not projected on the projection unit 4 a of the material reading device 4. When the text analysis unit 221 converts the image (material image) obtained by photographing the projection unit 4a into text, the text content is not projected on the projection unit 4a, and thus a character string is not extracted. That is, in this case, the text analysis unit 221 determines that the character string cannot be extracted.

  When it is determined that the character string cannot be extracted (NO in step S23), the text analysis unit 221 assumes that the material content is not projected on the projection unit 4a as described above and the material is not used in the meeting. Determination is made (step S25).

  For example, the above-described processing is performed on all materials projected on the projection unit 4a in the meeting. In this case, for example, the material reading unit 4b captures the content of the material projected on the projection unit 4a at regular intervals. At this time, when the material image photographed at a constant interval changes from, for example, the material image photographed last time, the above-described processing is performed on the material image. Further, for example, when the document image photographed at regular intervals changes, a flag may be set for the document image, and the above-described processing may be performed by collecting the document images with the flag set.

  Next, details of the process (indicator replacement process) of step S17 of FIG. 9 will be described with reference to the flowchart of FIG.

  First, the text analysis unit 221 extracts (acquires) a directive from words extracted by performing morphological analysis on a character string (step S31).

  Note that the storage unit 12 stores in advance a grammatical rule database (not shown) for directives that may be extracted, for example. The grammar rule database stores, for example, a directive, a range in which an antecedent of the directive exists, a grammar, a meaning, and the like. Examples of the range in which the antecedent precedent is present include, for example, the sentence immediately before the sentence in which the directive appears. Examples of grammar include nouns. Moreover, a person or a place etc. are mentioned as a meaning.

  That is, the text analysis unit 221 extracts a directive by referring to the grammar rule database.

  Next, the text analysis unit 221 extracts the antecedent candidate of the directive from the words that appear in the range where the antecedent of the directive stored in the grammar rule data exists, for example (step S32).

  The text analysis unit 221 determines whether or not the extracted antecedent candidates match grammatically (step S33). That is, for example, it is determined whether or not the extracted antecedent candidate is a noun, for example.

  When it is determined that the extracted antecedent candidate matches grammatically (YES in step S33), the text analysis unit 221 determines whether the antecedent candidate matches semantically (step S34). . Specifically, for example, when the instruction word is “there”, it is determined whether or not the meaning of the antecedent candidate indicates “location”.

  When it is determined that the extracted antecedent candidate matches semantically (step S35), the text analysis unit 221 replaces the directive extracted in step S31 with the antecedent candidate (step S35).

  On the other hand, if it is determined in step S33 that the antecedent candidates do not match grammatically, the process returns to step S32 and the process is repeated. When it is determined in step S34 that the antecedent candidates do not match semantically, the process returns to step S32 and the process is repeated.

  If all the predecessor candidates (words) that appear in the range where the antecedent of the directive stored in the grammar rule database does not match grammatically or semantically, the replacement processing of the directive is Not executed.

  Next, with reference to the flowchart of FIG. 12, the process sequence of the context formation word set extraction process by the context formation word set extraction part 222 is demonstrated in detail.

  First, the context-forming word set extraction unit 222 acquires words (word series and compound noun) stored in the storage unit 12 (step S41).

  The context forming word set extraction unit 222 identifies the number of appearances of each acquired word. Thereby, the context formation word set extraction unit 222 arranges the acquired words in the order of the specified number of appearances (step S42).

  The context-forming word set extraction unit 222 acquires the top n words among the words arranged in the order of appearance count (step S43). Here, n is a predefined value.

  Next, the context-forming word set extraction unit 222 extracts a context-forming word set (first context-forming word set) from the acquired top n words using, for example, the lexical linkage hypothesis described above. (Step S44). The context formation word set extraction unit 222 extracts a context formation word set that is a set of words that appear close to each other in the character string analyzed by the text analysis unit 221 from the acquired top n words. .

At this time, the context forming word set extraction unit 222 selects a set of two words included in the acquired top n words. The context forming word set extraction unit 222 calculates the co-occurrence degree (first co-occurrence degree) of the selected two word sets. Here, for example, the co-occurrence degree co (wi, wj) of two words wi and wj included in the text (character string) D is defined as follows.

Here, | x | _s in Equation (1) is the number of occurrences of the word x in the sentence s constituting the text D. This expression (1) represents the co-occurrence degree that the word wi that appears in a sentence s is considered to co-occur with all wj in the sentence s. That is, the co-occurrence degree is represented by the product of the number of times each of the two selected words appears in the same sentence in the sentence included in the character string subjected to the text analysis processing by the text analysis unit 221 described above.

  The degree of co-occurrence is calculated for all combinations of two words included in the top n words in the acquired top n words.

  The context-forming word set extraction unit 222 arranges the sets of two words whose co-occurrence degrees are calculated in descending order of co-occurrence degrees. The context-forming word set extraction unit 222 acquires the top n sets in descending order of, for example, co-occurrence. Here, n is a predetermined value. The context forming word set extraction unit 222 extracts each of the acquired top n sets of words as a context forming word set.

  Of the acquired top n sets of word groups, a set (set) of words that are related to each other is extracted as one (one set) context forming word set. Specifically, for example, the acquired top n sets (here, n = 5) of word sets are (A, B), (C, D), (A, E), (B, E). , (F, G). Here, it is assumed that A to G are words. In this case, three context forming word sets including the words A, B, and E, a context forming word set including the words C and D, and a context forming word set including the words F and G are extracted.

  Next, with reference to the flowchart of FIG. 13, a keyword extraction process performed by the keyword extraction unit 223 will be described in detail.

  First, the keyword extraction unit 223 acquires words (word series and compound nouns) stored in the storage unit 12 (step S51).

  The keyword extraction unit 223 displays the degree of association (first association) indicating the rate (probability) that the acquired word appears close to the words constituting the context formation word set extracted by the context formation word set extraction unit 222. Degree) is calculated (step S52).

Here, if the acquired word (one of them) is W, the context forming word set is C, and the words constituting the context forming word set C are a, b, and c, the relevance key (W, C) is

  Is defined. Here, co (W, a) included in Expression (2) is the co-occurrence degree of the acquired word W and the word a included in the context-forming word set C as described above. Similarly, co (W, b) included in the expression (2) is a co-occurrence degree of the acquired word W and the word b included in the context-forming word set C, and co (W , c) is the co-occurrence degree of the acquired word W and the word c included in the context forming word set C.

  That is, the degree of association is calculated based on the degree of co-occurrence (third co-occurrence degree) between the acquired word W and each of the words a, b, and c constituting the context forming word set C.

  Next, the keyword extraction unit 223 arranges the acquired words in the order of the calculated relevance (step S53).

  The keyword extraction unit 223 selects, for example, nouns and compound nouns from the words arranged in order of relevance (step S54).

  The keyword extraction unit 223 extracts, for example, the top n words from the selected nouns and compound nouns as keywords (first keywords) in order of relevance (step S55). Here, n is a predetermined value.

  Next, with reference to the flowchart of FIG. 14, a processing procedure of processing for searching the semantic content of a keyword by the Internet search unit 224 will be described in detail.

  First, the Internet search unit 224 acquires keywords (keywords extracted by the keyword extraction unit 223) that are to be searched for meaning content (step S61).

  The Internet search unit 224 acquires the URL of the site and the search expression format included in the dictionary information including, for example, the search order “1” held in the semantic content search list stored in the storage unit 12 (step S62). That is, the URL and search expression format of the site associated with the search order “1” in the dictionary information are acquired.

  Next, the Internet search unit 224 creates a search formula based on the acquired keyword and search formula format (step S63). As described above with reference to FIG. 6, the Internet search unit 224 creates a search expression by, for example, applying a keyword to the search expression format.

  The Internet search unit 224 searches for the semantic content of the keyword in the site specified by the acquired URL, using the created search formula (step S64). That is, the Internet search unit 224 searches the meaning content of the keyword from information sources existing outside the idea support system, for example, via the Internet.

  The Internet search unit 224 determines whether the semantic content of the keyword has been acquired (step S65).

  When it is determined that the semantic content of the keyword can be acquired (YES in step S65), the Internet search unit 224 acquires configuration information held in the site configuration list stored in the storage unit 12 (step S66). . In this case, for example, configuration information including the search order “1” is acquired. That is, in the dictionary information held in the semantic content search list, configuration information including the search order associated with the URL acquired in step S62 and the search expression format is acquired.

  The Internet search unit 224 is configured to search the site where the semantic content of the keyword is searched based on the semantic content display unit and the image display unit included in the acquired configuration information (here, for example, the site name included in the acquired configuration information) The character string (text) representing the semantic content of the keyword and the (display) position of the image are specified (step S67).

  The Internet search unit 224 cuts out a character string and an image representing the semantic content of the keyword at the specified position in the site where the semantic content of the keyword is searched (step S68). As shown in FIG. 7, the Internet search unit 224, for example, in the site where the semantic content of the keyword is searched, the character string described in “in the <p> tag before the table of contents” and “directly under the search word” Cut out the image in "<image> tag" displayed in (Next).

  The character string and the image cut out by the Internet search unit 224 in this way are displayed on the display device 3 as the meaning content of the keyword.

  Here, it has been described that only one character string and image (keyword meaning content) extracted by the Internet search unit 224 is displayed. However, a configuration in which a plurality of meaning contents are displayed may be used. In this case, for example, the semantic content of the keyword is searched from a plurality of sites in the higher search order included in the dictionary information held in the semantic content search list.

  On the other hand, if it is determined in step S65 that the semantic content of the keyword cannot be acquired, that is, if the semantic content of the keyword is not held in the site specified by the URL acquired from the semantic content search list, for example, Returning to S62, the process is repeated. In this case, in step S62, for example, the URL of the site and the search expression format included in the dictionary information including, for example, the search order “2” held in the semantic content search list are acquired, and the processing from step S63 onward is executed. . That is, the processing is executed in the search order held in the semantic content list until the semantic content of the keyword is acquired.

  Next, with reference to the flowchart of FIG. 15, a processing procedure of processing for searching (extracting) an idea support word by the Internet search unit 224 will be described in detail.

  First, the Internet search unit 224 acquires the context formation word set (first context formation word set) extracted by the context formation word set extraction unit 222 and the keyword (first keyword) extracted by the keyword extraction unit 223. (Step S71).

  Next, the Internet search unit 224 creates a search expression for searching for information (for example, a site or a document) including the words constituting the acquired context-forming word set (step S72). In this case, for example, a search expression for searching a site including all the words constituting the context forming word set is created.

  The Internet search unit 224 searches for a site including the words constituting the acquired context forming word set using the created search formula (step S73). The Internet search unit 224 searches for sites including words constituting the context-forming word set from information sources existing outside the idea support system via the Internet, for example.

  Here, a text analysis process (the processes in steps S15 to S18 shown in FIG. 9) is executed on the character string (second character string) included in the searched site. For example, the text analysis unit 221 extracts a word (second word) included in the character string by performing morphological analysis on the character string included in the searched site. The text analysis unit 221 performs compound noun creation and indicator replacement processing on the extracted word as described above. The text analysis unit 221 stores the extracted word in the storage unit 12.

  As described above, when the text analysis process is executed, the context-forming word set extraction process (the processes in steps S41 to S44 shown in FIG. 12) is performed on the words stored in the storage unit 12 in the text analysis process. Executed. That is, the context forming word set 222 obtains the top n words in the order of appearance among the words stored in the storage unit 12 (words extracted by morphological analysis of the character string included in the searched site). To do. The context forming word set extraction unit 222 calculates the co-occurrence degree (second co-occurrence degree) of a set of two words included in the acquired top n words. For example, the context forming word set 222 acquires the top n pairs in descending order of the calculated co-occurrence degree. The acquired top n sets of words are extracted as a context forming word set (second context forming word set).

  The text analysis process and the context-forming word set extraction process are executed for all the sites searched in step S72.

  The Internet search unit 224 acquires the context formation word set (second context formation word set) extracted by the context formation word set extraction process (step S74).

  Next, the Internet search unit 224 includes, in the acquired second context forming word set, a second context forming word set that is the same as the first context forming word set acquired in step S71 described above. Whether or not (step S75).

  Here, it is assumed that it is determined that there is a second context forming word set identical to the first context forming word set (YES in step S75). In this case, keyword extraction processing (step S51 to step S51) is performed on the word and the second context forming word set stored in the storage unit 12 by the text analysis processing on the character string included in the site searched in step S73. Step S55) is executed. The keyword extraction unit 223 includes words stored in the storage unit 12 (words extracted by morphological analysis of character strings included in the searched site) and words constituting the second context forming word set. Based on the co-occurrence degree with each (fourth co-occurrence degree), the relevance degree (second relevance degree) is calculated. This degree of association indicates a rate at which the words stored in the storage unit 12 appear close to the words constituting the second context forming word set. The keyword extraction unit 223 extracts the top n words as keywords (second keywords) in the calculated order of relevance.

  The Internet search unit 224 acquires the keyword (second keyword) extracted by the keyword extraction process (step S76).

  Next, the Internet search unit 224 determines whether or not the acquired second keyword includes a second keyword different from the first keyword acquired in step S71 described above (step S77). .

  When it is determined that there is a second keyword different from the first keyword, the Internet search unit 224 acquires (extracts) a second keyword different from the first keyword as an idea support word (step S78).

  On the other hand, if it is determined in step S75 described above that there is no second context forming word set identical to the first context forming word set, the idea support word search (extraction) process is terminated.

  If it is determined in step S77 that there is no second keyword different from the first keyword, the idea support word search (extraction) process is terminated.

  Next, with reference to FIG. 16, for example, during a conference, a display example when the display device 3 displays a context-forming word set, a keyword, a semantic content of the keyword, and an idea support word in the conference content will be described. .

  The context forming word set, the keyword, the semantic content of the keyword, and the idea support word are displayed on the display device 3 by the display control unit 23 included in the idea support device 2.

  At this time, the display control unit 23 performs control to display the context forming word set, the keyword, the semantic content of the keyword, and the idea support word based on the rule information stored in the storage unit 12 described above, for example. The rule information stored in the storage unit 12 indicates, for example, a rule (display rule) for displaying on a predetermined display device 3.

  Here, as shown in FIG. 16, on the display device 3, for example, context-forming word sets 1 and 2, keywords 1 to 3, and idea support words 1 to 4 are displayed. The context forming word set 1 includes context forming words 1 to 3. The context forming word set 2 includes context forming words 4 and 5.

  Hereinafter, a specific example of the display rule indicated by the rule information stored in the storage unit 12 will be described. The display rules include, for example, rules relating to character string display specifications, rules relating to line display specifications, and rules relating to display positions.

  First, the rules regarding the display specification of the character string include, for example, first and second rules. In the first rule, as shown in FIG. 16, for example, a context-forming word, a keyword, and an idea support word are distinguished by a figure of a frame surrounding each word. In the example shown in FIG. 16, for example, context forming word sets 1 and 2 are displayed surrounded by a square frame 301, for example. The context forming word sets 1 and 2 are displayed with a background in the frame 301. This makes it easier to recognize the context-forming word sets 1 and 2. In addition, the context forming words 1 to 5 included in the context forming word sets 1 and 2 are displayed surrounded by a square frame 302, for example. On the other hand, the keywords 1 to 3 are displayed surrounded by a circle (ellipse) frame 303, for example. The idea support words 1 to 4 are displayed surrounded by a circle (ellipse) frame 304, for example, as in the keywords 1 to 3. As a result, the type of each word (context-forming word set, keyword, and idea support word) can be visually recognized with a figure of a frame surrounding each word. As shown in FIG. 16, the semantic contents of each of the keywords 1 to 3 are displayed in the vicinity of the keywords 1 to 3.

  In the second rule, as shown in FIG. 16, for example, a keyword and an idea support word are represented by a frame (line) surrounding each word and a line (joint line) connecting each word and the context-forming word set. Differentiated. In the example illustrated in FIG. 16, for example, the frame 303 surrounding the keywords 1 to 3 is displayed with a thick line. Further, for example, the connecting line 305 between the keywords 1 and 2 and the context forming word set 1 is displayed as a thick line. Similarly, the connecting line 305 between the keywords 2 and 3 and the context forming word set 2 is displayed as a thick line. On the other hand, a frame 304 surrounding the idea support words 1 to 4 is displayed by a thin line. Further, for example, the connecting line 306 between the idea support words 1 and 2 and the context forming word set 1 is displayed as a thin line. Similarly, the connection line 306 between the idea support words 3 and 4 and the context forming word set 2 is displayed as a thin line. Thereby, a keyword and an idea support word can be visually recognized.

  Next, the rule regarding the display specification of the line includes, for example, a third rule. In the third rule, as shown in FIG. 16, for example, context forming words (sets), keywords, and idea support words are distinguished by the types of lines (joining lines) connecting the words. In the example shown in FIG. 16, the connecting line 307 that connects the context forming words 1 to 3 included in the context forming word set 1 is displayed with a dotted line. Similarly, a connecting line 307 that connects the context forming words 4 and 5 included in the context forming word set 2 to each other is indicated by a dotted line. On the other hand, the connecting line 305 connecting the context forming word set 1 and the keywords 1 and 2 is displayed as a solid line. Also, the connecting line 305 that connects the context forming word set 2 and the keywords 2 and 3 is displayed as a solid line. Similarly, the connecting line 306 that connects the context forming word set 1 and the idea support words 1 and 2 is displayed as a solid line. Also, the connecting line 306 that connects the context forming word set 2 and the idea support words 3 and 4 is indicated by a solid line.

  Next, the rules regarding the display position include, for example, fourth and fifth rules. In the fourth rule, as shown in FIG. 16, for example, the strength of the relevance described above is expressed using a spring model. Specifically, for example, the strength of the degree of association is expressed by the distance at which the context forming word set, the keyword, and the idea support word are displayed. In the example shown in FIG. 16, for example, when the idea support word 1 and the idea support word 2 are compared, the idea support word 2 is displayed closer to the context forming word set 1 than the idea support word 1. Thereby, it can be visually recognized that the idea support word 2 is more relevant than the idea support word 1.

  In the fifth rule, as shown in FIG. 16, for example, the transition of the topic in the conference is represented by the display position of each word on the screen of the display device 3. In the example illustrated in FIG. 16, for example, the arrow 400 indicates a topic transition in the conference. In this case, for example, the context forming word set 1 is first extracted at the beginning of the meeting, and then the context forming word set 2 is extracted by the progress of the meeting. Thereby, the transition of the topic in a meeting can be confirmed visually.

  In addition to the first to fifth rules described above, there may be a display rule that distinguishes between colors such as a frame line, a frame line, and a character itself. The display rule may be any display rule as long as it can visually distinguish the context-forming word set, the keyword, and the idea support word such as a shape of a surrounding line. Rules are possible.

  As described above, in the present embodiment, for example, a conversation in a conference is recorded, and from the recorded conversation, a context forming word set indicating the basis or background of the conversation (meeting content) is extracted. The In the present embodiment, keywords appearing in the recorded conversation are extracted. In the present embodiment, the semantic content of the extracted keyword is searched through the Internet, for example. Moreover, in this embodiment, the idea support word for expanding the idea of the participant of a meeting is searched and extracted via the internet, for example. Thereby, in this embodiment, it becomes possible to show the extracted context formation word set, the keyword, the meaning content of the keyword, and the idea support word to the conference participants.

  That is, in the present embodiment, for example, conversation contents (context forming word set, keyword and meaning contents of the keyword) and the next conversation candidate (concept support word) in a meeting can be automatically visualized.

  Therefore, for example, by confirming the presented context-forming word set, the keyword, and the semantic content of the keyword, for example, all the participants in the conference can understand and share the content of the conference. Become. Further, by confirming the presented idea support word, it is possible to expand (support) ideas that are not spread only by the participants, for example. Thereby, for example, it becomes possible to activate a place called a conference space in a company or the like.

  In the present embodiment, for example, the meaning content of the keyword and the idea support word have been described as being searched via the Internet. However, the search may be performed via the intranet, for example.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment.
