Description

The present invention relates to an information providing system and an information providing method.

Conventionally, for example, in order to search for information existing on the Internet, Google (registered trademark) or Yahoo! Information provision systems such as (registered trademark) are used. These information providing systems are full-text search methods that extract information such as documents to be searched by full-text search based on acquired information such as words input from a user terminal.

In such a full-text search type information providing system, it is not possible to obtain realistic performance by simply performing a full-text search targeting a large number of documents, etc., so a search is performed in order to execute the search process at high speed. A full-text search method in which an index for this is created in advance is widely used. An index is a data structure that associates a substring such as a word or phrase with a document in which the substring appears. The substring to be stored in the index is a so-called headword, and usually, not the document itself but only the information that identifies the document in the form of a document ID is recorded in the index.

For example, Patent Document 1 discloses a search device that performs a search using an index. The search device disclosed in Patent Document 1 includes an index for storing a correspondence between a headword and a document including the headword, an index management means, and a document search means. Then, when the index management means registers the first document in the search target document set, among the words included in the first document, the words already registered as headwords in the index are the first document. For words that have been indexed as headwords and have not yet been registered as headwords in the search index, when there is a request to register another second document that cites the first document in the search target document set. Register in the index as the headword of the first document. Then, the document search means searches the index for a document containing a headword that matches the search keyword at the time of a search request.

With such a configuration, in the search device disclosed in Patent Document 1, words appearing only in non-important documents that are not quoted from other documents are not registered in the index as headwords, so that the non-important documents can be used. We are trying to prevent the index from becoming bloated.

Further, the function of the information providing system 100A may be controlled by, for example, artificial intelligence. Here, the "artificial intelligence" may be based on any well-known artificial intelligence technology.

<User terminal 2>
As shown in FIG. 1, the user terminal 2 is a personal computer (PC) like the information providing device 1, and is a client to which the user U receives a service from the information providing device 1 which is a host computer via the communication network N. It is a computer.

As an example, the user terminal 2 is a terminal of a user U such as an engineer who uses the measuring instrument X. The user terminal 2 includes a keyboard 11A for inputting character information, a microphone 11B for inputting voice information, a Web camera 11C for inputting image information, a display 21 as an output unit, and a mouse 22. It is connected to the communication network N by an interface (not shown).

The Web camera 11C for inputting image information may use an HMD (head-mounted display) such as a holo lens (registered trademark) instead. The user terminal 2 is not limited to a personal computer (PC), and is not limited to electronic devices such as mobile phones (mobile terminals), smartphones, tablet terminals, wearable terminals, and IoT (Internet of Things) devices. Those embodied in any electronic device may be used. The user terminal 2 may be connected to the information providing device 1 via, for example, the communication network N, or may be directly connected to, for example, the information providing device 1.

Further, although the user terminal 2 and the information providing device 1 are both personal computers (PCs), the information providing device 1 has a higher processing capacity so as to be able to respond to search requests of a plurality of user terminals 2. Is preferably used.

<Server S>
In the server S, the actual data of a document such as a manual of the instrumentation device X provided to the user terminal 2 of the user U is stored in the storage S1 (see FIG. 3). When the communication network N is not used, the actual data of the document such as the manual of the instrumentation device X provided to the user terminal 2 of the user U may be stored in, for example, the storage unit 104 of the information providing device 1. good.

FIG. 3 is a schematic diagram showing the configuration of the information providing system 100A. FIG. 4 is a flowchart showing an information providing method according to the first embodiment. The information providing system 100A includes a search key acquisition unit 11 included in the user terminal 2, a target information specifying unit 12 included in the information providing device 1, a search processing unit 13, a search result output unit 14, and a document output unit 15. , Is equipped.

<Search key acquisition unit 11>
Specifically, the search key acquisition unit 11 is any one of the keyboard 11A, the microphone 11B, or the Web camera 11C in the user terminal 2. When the search key is acquired by the character information acquisition method, the search key is input by character input using the keyboard 11A, and the search key is acquired as character information. When the search key is acquired by the voice information acquisition method, it is acquired as voice information by inputting the search key by voice input by the microphone 11B. The voice information acquired by the voice information acquisition method is converted into character information in the user terminal 2 by a voice information / character information conversion means (not shown). When the search key is acquired by the image information acquisition method, the image information by the Web camera 11C is converted into character information according to the recognition result of the image recognition artificial intelligence built in the information providing device 1 or the user terminal 2 (not shown). Obtained as a search key by. Alternatively, when the search key is acquired by the image information acquisition method, it may be acquired as image information by inputting the search key in the image input by the Web camera 11C.

Specifically, for example, the user U uses the name of the instrumentation device X and the model number X1 as a search key, or a broad wording such as an operation method or a narrow wording (scene name) representing various operation scenes. Alternatively, when an image including an image of the instrumentation device X is input by the keyboard 11A, the microphone 11B, or the Web camera 11C, the search key acquired as the character information or the image information is transmitted from the user terminal 2 to the communication network N. It is sent to the target information specifying unit 12 in the information providing device 1 via the information providing device 1 (search key acquisition step S11).

Here, the search key acquisition method in the search key acquisition step S11 is not limited to a single acquisition method of the character information acquisition method by the keyboard 11A, the voice information acquisition method by the microphone 11B, and the image information acquisition method by the Web camera 11C. .. For example, if the information is insufficient because the model number X1 of the instrumentation device X is not reflected only by the image information acquisition method by the Web camera 11C, the character information acquisition method by the keyboard 11A or It can be supplemented by the voice information acquisition method using the microphone 11B. That is, the character information acquisition method using the keyboard 11A, the voice information acquisition method using the microphone 11B, and the image information acquisition method using the Web camera 11C may be used in combination instead of single.

<Target information identification unit 12>
The target information specifying unit 12 is provided inside the information providing device 1, and is connected to the target information specifying database 16 also provided inside the information providing device 1. In the target information identification database 16, a list of target information for specifying the search key sent from the search key acquisition unit 11 is stored. The list of target information stored in the target information identification database 16 may be diverted if it is available in advance, or a newly generated list may be automatically or manually created and added. good.

Specifically, the target information identification unit 12 uses the target information corresponding to the search key acquired as the character information or the image information sent from the search key acquisition unit 11 as the target information in the target information identification database 16. Search from the list of, and perform the process of associating with the target information. Then, the search key acquired from the search key acquisition unit 11 and the target information specified by the target information identification unit 12 are sent to the search processing unit 13 (target information identification step S12).

<Search processing unit 13>
The search processing unit 13 is provided inside the information providing device 1, and is connected to a search processing database 17 also provided inside the information providing device 1. An index for use in the search process is stored in the search process database 17.

The index stored in the search processing database 17 is created for each document pattern by preparing a data set of a document structure including a table of contents in the document and keywords (tags / meta information) for the table of contents items as many as the number of document patterns. There is. Specifically, a keyword for a table of contents item can be used as an index for each document pattern. Documents with the same document pattern have similar contents, so the keywords are almost the same. Therefore, the keyword for each document pattern can be used as an index.

Here, the keyword is extracted from the text of the document corresponding to the table of contents item by an extraction unit (not shown). The extraction method may be a word importance extraction method of an existing document such as a treatise or an open source library, or may be performed manually. The keywords of non-structural information such as images in the data may be extracted by performing annotation work.

As for the method of creating this index, documents used for business (for example, documents such as manuals) are already in the almost completed stage, and even if the brands and grades are different, the document structure is almost the same. In most cases, there are only a few document patterns, so I focused on that and came up with my own ideas. For example, even if there are 1000 documents for the same subject, it was found that the number of document patterns is usually about 2 or 3 documents. That is, the index is sampled, and the index is significantly smaller than that of the prior art. The difference between the document patterns is that, for example, the table of contents item contains all the sentences, and the table of contents item contains rough sentences, and additional details and annotations are written below the table of contents. Is often the difference from the one described.

The search processing unit 13 uses this significantly small amount of index to perform search processing based on the keywords (tag / meta information) obtained from the search key acquired from the search key acquisition unit 11. Then, the search processing unit 13 sends the target information specified by the target information specifying unit 12 and the search processing result by the search processing unit 13 to the search result output unit 14 (search processing step S13).

<Search result output unit 14>
The search result output unit 14 is provided inside the information providing device 1, and is connected to the search result output database 18 also provided inside the information providing device 1. In the search result output database 18, the actual document corresponding to the search result obtained by hitting the target information specified by the target information specifying unit 12 and the search processing result by the search processing unit 13. Only the link information in the data link list is stored. Then, the search result output unit 14 outputs and displays the link list of the search result on the display 21 of the user terminal 2 via the communication network N. Specifically, a link list of actual data of a document such as a manual of the instrumentation device X is output and displayed (search result output step S14).

<Document output unit 15>
The document output unit 15 is provided inside the information providing device 1, and is connected to the storage S1 in the server S via the communication network N. Then, when the user U selects one of the link lists of the search results by using the mouse 22 or the like, the document output unit 15 issues a command and displays the selected document on the display 21 of the user terminal 2. Data is output and displayed (document output step S15).

The actual data of the document that can be output by the document output unit 15 includes not only the document text but also contents in which illustrations, image data, moving image data, audio data, and the like are attached or linked to the document text.
