Description

  The present invention relates to an information processing apparatus, an information processing system, a control method, and a program that improve the efficiency of a search target search method.

  In order to develop products and services from the customer's perspective, use customer opinions such as expectations, requests, and dissatisfactions about products and services, such as inquiries to contact centers, questionnaires and SNS comments. It is important to.

  As a technique for searching interesting information and analyzing trends from a large amount of text data, there is a technique called “text mining”, and many companies have released text mining products.

  However, text mining is not a technology in which a computer understands the contents of a huge amount of text data and outputs knowledge that is useful to humans. Therefore, the text mining tool is required to have an easy-to-understand interface for human users.

  In order to obtain knowledge from enormous text data, it is necessary to visualize the data from various viewpoints such as narrowing down by attribute information such as age and gender and data including some words, and repeat trial and error.

  For this reason, the search formula used to search for data can be easily generated by the user, and the meaning of the search formula can be understood at a glance in the analysis process so that the analysis result is not misidentified. It is desirable to be presented.

  Therefore, a method for automatically generating a search expression by dragging or clicking on a word or phrase included in a sample document and presenting it to a user in the form of a tree structure is disclosed for the difficulty of creating a search expression. (For example, refer to Patent Document 1).

  Further, in order to support the creation of a search expression using a plurality of words, a technique is disclosed in which words are classified into categories, words in the same category are treated as OR combinations, and categories are treated as AND combinations (for example, Patent Document 2).

  Furthermore, in order to present an intuitively understandable and amendable search expression, a method of displaying a tree structure in which an AND condition is a parent-child relationship and an OR condition is a sibling relationship is disclosed (for example, a patent) Reference 3).

  For the analysis analyst who is familiar with the information technology (understands that the search expression can be expressed in the tree structure), the display method of the search expression by the tree structure in the inventions described in Patent Document 1 and Patent Document 3 is usually used. Although it can be said that it is an easy-to-understand format, users who use text mining tools do not always have the same skills, and it is not necessarily a structure that is easy to understand intuitively for users of tools. .

  In addition, the expression of a search expression using a tree structure makes it easy to edit the search expression, but requires a lot of space to display the screen. If the analysis result is presented at the same time as the visualization area, the analysis result can be viewed. To reduce the space to do it.

  At this time, it is possible to temporarily hide the area of the search expression displayed as a tree structure, but in order to prevent the tool user from misinterpreting the analysis result being displayed It is desirable that the search expression is always displayed in an easily understandable manner.

  In the invention described in Patent Document 2, a word used as a search expression in a node format is displayed, and a word belonging to the same group is implicitly treated as an OR combination and a group is treated as an AND combination. The structure of is easily visualized.

  However, a user of a text mining tool does not necessarily want to treat it as an OR combination in a set of words handled as the same group, and there are not a few cases where he wants to search for a document containing both words.

  Further, in the invention described in Patent Document 2, a method for creating a search formula for the entire text is described. However, in a text mining tool, the data item to be searched is not necessarily one type. In the attribute information (poster's age, gender, etc.) and the data such as questionnaires, multiple free description fields can be searched. Therefore, it is necessary to visualize the search expression considering the items to be searched. Become.

  Accordingly, an object of the present invention is to provide a mechanism for efficiently searching for a search target.

  In order to solve the above-described problem, the present invention provides an information processing apparatus that displays a document on a display unit, the item receiving unit receiving selection of an item to be displayed on the display unit, and the item based on information on the document. Display means for displaying information relating to the element on the display unit, and item element accepting means for accepting selection of information relating to the element of the item displayed on the display part, wherein the display means includes the item A document to be displayed on the display unit is selected and displayed using information relating to the element of the item received by the element receiving means.

  According to the present invention, there is an effect that a search target can be efficiently searched.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic configuration of an information processing system that analyzes a customer's voice about a product or service such as a customer included in the text data by performing text mining on the text data.

  The information processing system 100 includes a client terminal 102 that displays a result of text mining performed on text data, and an information processing apparatus 104 that accumulates text data and performs text mining. Are connected so that they can communicate.

  Next, an example of a hardware configuration applicable to the client terminal 102 and the information processing apparatus 104 will be described with reference to FIG.

  In FIG. 2, reference numeral 201 denotes a CPU that comprehensively controls each device and controller connected to the system bus 204. Further, the ROM 202 or the external memory 211 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 201, or a function executed by each server or each PC. Various programs to be described later are stored.

  A RAM 203 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program or the like necessary for execution of processing from the ROM 202 or the external memory 211 into the RAM 203 and executing the loaded program.

  An input controller 205 controls input from a keyboard (KB) 209 or a pointing device such as a mouse (not shown). A video controller 206 controls display on a display device such as a CRT display (CRT) 210.

  In FIG. 2, although described as CRT 210, the display device is not limited to the CRT, but may be another display device such as a liquid crystal display. These are used by the administrator as needed.

  A memory controller 207 is connected via an adapter to a hard disk (HD), flexible disk (FD), or PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, and the like. The access to the external memory 211 such as a compact flash (registered trademark) memory is controlled.

  A communication I / F controller 208 is connected to and communicates with an external device via a network (for example, the network 106 shown in FIG. 1), and executes communication control processing on the network. For example, communication using TCP / IP is possible.

  Note that the CPU 201 enables display on the CRT 210 by executing outline font rasterization processing on a display information area in the RAM 203, for example. In addition, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the CRT 210.

  Various programs to be described later for realizing the present invention are recorded in the external memory 211 and executed by the CPU 201 by being loaded into the RAM 203 as necessary. Furthermore, definition files and various information tables used when executing the program are also stored in the external memory 211, and a detailed description thereof will be described later.

  Next, functional configurations of the client terminal 102 and the information processing apparatus 104 will be described with reference to FIG. The details of each function will be described together with the description of the screen.

  The client terminal 102 includes a display unit 300 and a search unit 302. The display unit 300 displays information related to a document stored in the information processing apparatus 104 and information related to a result obtained by analyzing the information related to the document. To do.

  In addition, the display unit 300 accepts designation of a search condition and displays information on information on a displayed document and information on a result obtained by analyzing information on the document.

  The search unit 302 uses the search condition displayed on the display unit 300 to search the information processing apparatus 104 for information related to the document to be displayed on the display unit 300.

  The information processing apparatus 104 includes a storage unit 304 and an analysis unit 306, and the storage unit 304 includes information to be analyzed (for example, information on products, report information such as surveys, quality inspections, and fault inspections) Records information on questionnaires, sales activities, work, etc., patent documents, academic papers, market information / news, technical and academic specialized field information, etc.).

  The storage unit 304 stores information related to the search condition displayed by the display unit 300.

  The analysis unit 306 analyzes the information to be analyzed stored in the storage unit 304 by applying a technique such as text mining.

  Next, as an example of information to be analyzed, as shown in FIG. 4, a posting date and time indicating the date and time posted to the SNS, a product indicating what product the posted content was made, and the posted content , Comments about the product, the age of the poster, and oral information including the gender of the poster.

  Text data having such information is acquired from the storage unit 304, analyzed by a text mining tool by the analysis unit 306, and information related to the analysis result is displayed on the analysis screen 400 (see FIG. 5) by the display unit 300. indicate.

  FIG. 5 shows a configuration of the analysis screen 400, and the analysis screen 400 includes a search condition operation area 402, a viewpoint display area 404, and an analysis result display area 406.

  FIG. 6 illustrates a search condition operation area 402, which includes a search condition addition icon 500, a search condition return icon 502, a search condition storage icon 504, a document number display area 506, and a search condition visualization area 508.

  The search condition visualization area 508 includes a plurality of nodes (hereinafter referred to as search condition nodes) having an item name representing a search target item and a label representing a value of the search condition.

  As an item to be searched, for example, as illustrated, “comment.word”, “product”, and “evaluation” are displayed, and “comment.word” is displayed by the analysis unit 306 as a “comment” item. On the other hand, it represents a word set analyzed and extracted from text data such as oral information by morphological analysis technology, and “product” and “evaluation” represent items such as products and evaluations included in oral information.

  The search condition nodes are grouped and displayed for each item to be searched by the display unit 300, and a character string representing the search condition is displayed on the label of the search condition node.

  For example, as shown in the figure, the search condition node 510 represents a search condition regarding “words included in a comment”, and is a condition for narrowing down documents including the word “image quality” in the comment item. .

  In the search condition node, the display unit 300 displays the character string “-” indicating that the NOT condition is the NOT condition at the head of the label and the color of the search condition node is changed.

  For example, the search condition node 512 represents a NOT condition for the word “clean”, and is a condition for narrowing down documents that do not include the word “clean” in the comment item.

  In the search condition node, the condition expression for OR combination is displayed on the label in the search condition node by the display unit 300 with a character string “OR” indicating that it is OR combination between the character strings representing the value of the search condition. Is done.

  For example, the search condition node 514 is a condition for narrowing down documents that include either “product B” or “product C” in the product item.

  It is possible to create a search expression using equal signs and inequality signs in items that represent quantity and date / time. In the search condition node, conditional expressions that contain equal signs or inequality signs are the characters that represent the symbols at the beginning of the label. It is displayed on the display unit 300 by adding a column.

  For example, the search condition node 516 is a condition for narrowing down documents whose evaluation item is “3 or more”.

  Note that all the search condition nodes displayed in the search condition visualization area 508 form a search expression by AND combination.

  As described above, the search expression shown in the search condition visualization region 508 in FIG. 6 has the same meaning as the logical expression shown in FIG. 7 or the search expression represented by the tree structure shown in FIG. .

  The search condition visualization area 508 groups search conditions for the same item, simplifies a character string indicating the search conditions, and displays it as a node label by the display unit 300, thereby suppressing the display area of the search condition expression. Visualization in a format that is easy for humans to understand.

  As a constraint for grouping and organizing search conditions for the same item, OR join in different search target items may not be expressed, but this problem is solved in the search condition group registration process described later. It is possible.

  Next, a method for creating a search condition node will be described. There are five methods for creating search condition nodes: creation by form input, creation by operation of search condition nodes, creation by selection of item values, creation by selection of values of search condition groups, and creation by operation of the analysis result display area. Separated.

  First, a creation method by form input will be described with reference to FIG. An input form for adding a search condition is displayed on the search condition operation area 402 by the display unit 300 when the search condition addition icon 500 is clicked.

  FIG. 9A shows the search condition operation area 402 after the search condition addition icon 500 is clicked.

  A form for adding a search condition includes a search object item selection button 600 and a search expression input form 602.

  The search target item selection button 600 is a button for changing a search target item used as a search expression. When the search target item selection button 600 is clicked, a search target item selection drop-down list 604 shown in FIG. indicate.

  The search target item displayed in the search target item selection drop-down list 604 displays, for example, each item of the above-described oral information by the display unit 300, and for the comment, a characteristic word of the comment is displayed (comment.word ), The dependency relationship between words is displayed on the display unit 300 (comment. Dependency).

  In the search target item selection drop-down list 604, the symbols “t_”, “w_”, and “#_” in front of the item name represent the data type of the item value, and each is “date and time type”. , “Character string type” and “numerical type”.

  The search formula input form 602 receives a search formula corresponding to the data type of the item value by the display unit 300. For example, for an item “product” that is a character string type, a wild card such as “*” representing an arbitrary plurality of characters or “?” Representing an arbitrary character can be used.

  FIG. 9C shows a state in which “product A *” is input as a search expression. The user confirms the content entered in the search expression input form 602 by inputting the Enter key, whereby the search condition node 606 shown in FIG.

  In addition, for the item “evaluation” which is a numerical type, a symbol representing a magnitude relationship by an equal sign or inequality sign can be used. FIG. 9E shows a state in which the search expression “> = 3” is input to the item “evaluation”. FIG. 9F shows that the search condition node 608 is created after the input is confirmed. It shows the state.

  As described above, the search expression input form 602 can input a search expression corresponding to the type of the search target item, and can generate a search condition node by confirming the input. In order to simplify the description, other data types and details of search expressions that can be used for each data type are omitted.

  Next, creation by operation of a search condition node will be described with reference to FIG. FIG. 10A is an example of a search condition node, and “Product B” is held by the display unit 300 as a search expression.

  The search condition node 700 displays a negative condition switching icon 702, a search expression edit icon 704, and a search condition deletion icon 706 shown in FIG. 10B on the display unit 300 by the user's hover operation (or touch operation). To do.

  The negative condition switching icon 702 is an icon for converting a search expression held by the search condition node into a NOT condition, and the search expression of the search condition node is rewritten by the display unit 300 by a click operation.

  FIG. 10C shows the search condition node 700 after clicking the negative condition switching icon 702, and the character string “-” indicating the NOT condition with respect to the original search expression “product B”. Is inserted.

  When a hover operation (or touch operation) is performed on a search condition node that is a NOT condition, an affirmative condition switching icon 708 is displayed instead of the negative condition switching icon 702 as shown in FIG. Displayed by the display unit 300.

  The affirmative condition switching icon 708 is an icon for removing the character string “-” indicating the NOT condition from the search condition node search expression, contrary to the negative condition switching icon 702.

  The search expression edit icon 704 is an icon for the user to directly edit the search expression held by the search condition node by form input.

  As a result of the click operation, as shown in FIG. 10E, the label of the search condition node 710 is replaced with an editable form, and the search expression can be directly edited.

  The search condition deletion icon 706 is an icon for deleting a search condition node. The search condition node is removed from the search condition operation area 402 by the click operation.

  The OR combination of search conditions can be realized by overlapping the search condition node with another search condition node by a drag and drop operation.

  FIG. 10F shows a state in which the search condition node 712 is dragged and superimposed on the search condition node 714. When the drop operation is completed, the two search condition nodes are merged, and FIG. ), A search condition node 716 having an OR condition as a search expression is generated by the display unit 300. The search condition node accepts a drop operation only for search condition nodes in the same group.

  As described above, the search condition node is a node capable of editing the search expression by a simple operation by the user.

  Next, creation of a search condition node by item value selection will be described with reference to FIG. FIG. 11A shows a viewpoint display area 404. The viewpoint display area 404 includes an item display area 800 and a search condition group display area 802.

  The item display area 800 is an area for displaying the total result for each item. By clicking the folder icon on the left side of the item name, each item value is displayed by the display unit 300 under the current search condition. The number of documents included can be displayed in a list. These items and the number of documents indicate the items and the number of documents related to the mouth information to be analyzed.

  FIG. 11B shows the viewpoint display area 404 after clicking the folder icon 804 in the “product” item, and the display unit 300 displays a document number list 806 for each item value in the product item. .

  Each item value in the document number list 806 for each item value is an area that can be selected by clicking. FIG. 11C shows a state where the item value “product B” and the item value “product C” are selected.

  By selecting one or more item values, a search condition node creation icon 808 is displayed on the right side of the item name. By clicking the search condition node creation icon 808, the user can add a search condition node that holds a search expression in which the selected item values are connected by an OR connection.

  Next, a method for creating a search condition node by selecting a search condition group value will be described with reference to FIGS. FIG. 12A is an example of the search condition operation area 402 and shows a state where three search condition nodes exist.

  When the user clicks the search condition storage icon 504, the search condition storage / edit form 900 shown in FIG. 12B is displayed on the CRT 210 by the display unit 300.

  The search condition storage / edit form 900 includes a search condition group name input form 902, a search condition name input form 904, a search condition input form 906, and a save button 908.

  Here, in the search condition input form 906, the search condition when the search condition storage icon 504 is clicked is input in advance in the form of the logical expression shown in FIG.

  The user can save the search condition in the storage unit 304 by inputting the search condition group name input form 902 and the search condition name input form 904 and pressing a save button 908.

  The search condition saved by the search condition saving / editing form 900 can be referred to from the search condition group display area 802 and used to create a search condition node.

  The search condition group display area 802 is an area for displaying the total result for each search condition. By clicking the folder icon on the left side of the search condition group name, the display unit 300 displays the current search condition. The number of documents that match each search condition can be displayed in a list.

  FIG. 13A shows a viewpoint display area 404 after the folder icon 1000 in the “customer group” group is clicked, and the display unit 300 displays a document number list 1002 for each search condition in the customer group group. ing.

  Each search condition name in the document number list 1002 for each search condition is an area that can be selected by clicking, and the selected search condition is used as the search condition in the same way as the method for creating a search condition node by selecting the item value described above. Can be created as a node.

  FIG. 13B shows the search condition operation area 402 after selecting the search condition “M1 layer” and clicking the search condition node creation icon, and the search condition node 1004 is created.

  The search condition operation area 402 is grouped by using the search condition group name in the search condition node related to the search condition stored with a name, and the search condition name is displayed on the label of the search condition node by the display unit 300. Is displayed.

  The search condition node 1004 created by selecting the value of the search condition group can perform almost the same operation as the search condition node described with reference to FIG. 10, but when the search expression edit icon 704 is pressed. The search condition storage / edit form 900 is displayed on the screen by the display unit 300 instead of the search condition node label being changed to the search expression input form.

  The method for creating a search condition node by selecting a search condition group value has been described above. Even in a complicated search condition, it is possible to significantly reduce the area required for visualization of the search condition by naming and saving it.

  In addition, the logical expression created as a search condition only needs to be checked for errors when creating the search condition, and by setting an appropriate search condition name, the risk of the user misidentifying the search condition during analysis is reduced. It becomes possible.

  Since the search condition input form 906 is edited in the form of a logical expression, it is possible to create a search condition for OR connection between different items.

  Next, a method for creating a search condition node by operating the analysis result display area 406 will be described with reference to FIG.

  The analysis result display area 406 is an area for visualizing data input to the text mining tool in various charts, and can display a plurality of charts at the same time. Hereinafter, the chart displayed in the visualization area is referred to as a visualization item.

  For example, FIG. 14A is an example of the analysis result display area 406. A time-series transition 1100 of the number of documents, a frequent word list 1102 that displays rankings of frequently occurring words in the document, and a document list 1104 Three visualization items are displayed on the display unit 300 at the same time.

  FIG. 14B shows an analysis result display area 406 in a state where the cross tabulation table 1112 is displayed as one visualization item.

  In addition, various visualization items can be displayed, such as displaying topics in the free description column in a network structure, displaying changes in topics in a tabular format, and displaying changes in the number of documents containing soaring words as a line graph. However, details are omitted to simplify the description.

  Note that each visualization item displayed in the analysis result display area 406 is automatically redrawn by the display unit 300 according to a change in the search condition.

  The user can generate a search condition node having information as an element as a search condition by the display unit 300 by pressing the element of each visualization item.

  For example, in the time series transition 1100 of the number of documents, by pressing an element 1106 indicating the number of documents posted in November 2017, a search condition node having a search condition that “post date / time” is November 2017 Is generated.

In addition, a search condition node having a search condition that “operability” is included in “comment.word” by pressing an element 1108 representing information of a document including “operability” in the list of frequently used words 1102 Is created. In other words, the search unit 302 searches for a document in which the word “operability” is included in the comment of the oral information, and the frequently used word list 1102 is displayed on the display unit 300 by “product”, “comment. , “Category”, etc., for example, by pressing the analysis item 1110, a drop-down list is displayed, and “Product”, “Comment.Feature word”, “ It is possible to display a “category” or the like and allow the user to select it.

  When “Product” is selected, the product ranking (number of documents for each product) is displayed. When “Comment.Feature word” is selected, the ranking of feature words included in the document is displayed, and “Category” is displayed. When is selected, the ranking for each product category is displayed. Each of these displays a ranking obtained by analyzing mouth information and the like.

  As a result, when all items are to be displayed to be displayed on the screen, the display area is narrow and it is difficult to see visually. By selecting an item to be focused on, it is possible to narrow down and search for documents, so that a visually good search can be performed.

  In the cross tabulation table 1112, by pressing an element 1114, two search condition nodes whose “age” is “30s” and search condition nodes whose “product” is “product B” are created.

  As described above, by operating the analysis result display area 406, the user can easily create a search condition for deepening a portion in which the user is interested.

  The created search condition nodes are automatically grouped according to the search target item or search condition group name by the search condition visualization area 508 and displayed on the display unit 300, so that the user is always organized. Analysis work can be performed while checking the search conditions.

  Next, a method of editing the visualization item in the analysis result display area 406 using the search condition node will be described with reference to FIG.

  The search condition node can be dragged. By dropping the search condition node on the visualization item, a cut according to the search condition can be added to the visualization item.

  FIG. 15A shows a search condition operation area 402 in a state where three search condition nodes are generated, and a time-series transition 1100 of the number of documents, which is an example of a visualization item.

  For example, as shown in FIG. 15B, the user can drag and drop the search condition node 1200 to the time series transition 1100 of the number of documents.

  FIG. 15C shows a search condition operation area 402 after the search condition node 1200 is dragged and dropped, and a time-series transition 1100 of the number of documents, which is an example of a visualization item.

  When the search condition node is dropped on the visualization item, the corresponding search condition node disappears, and the display unit 300 adds a cut according to the search condition to the visualization item to be dropped.

  In the above-described example, the search condition item name 1202 and the character string 1204 representing the search expression displayed as the label of the search condition node are displayed by the display unit 300 as the legend of the graph and match the search condition. The time series transition of the number of documents is displayed by the display unit 300 as a line graph 1206.

  The same effect can be obtained by dragging and dropping a search condition node created by selecting a search condition group value onto a visualized item.

  FIG. 16 shows a state after dropping two search condition nodes, a search condition node related to the “product” item and a search condition node related to the “customer layer” search group, from the state of FIG. .

  In this way, by using the search condition node, it is possible to easily create a chart having a complicated condition as a starting point.
