Description

  The present invention relates to an information providing system and an information providing program for detecting and providing information that matches a user's interest from information available on a network.

  With the development of networks such as the Internet, people can easily obtain information that suits their interests from the information available on the network. However, the amount of information provided to people via the network is enormous, and it is very time-consuming for the user to obtain appropriate information according to his / her interest from this enormous amount of information. .

In view of this situation, in recent years, a technique has been proposed in which input information and output information of a user are analyzed, and information that matches the user's interest is extracted and provided. The following Patent Document 1 is a system that is connected to a client terminal via a network, acquires an access history from the client terminal, generates a search condition expression, and includes information registered in the server device by an external organization. Discloses a system for providing information matching a search condition expression to the client terminal.
JP 2002-157270 A

  In recent years, a technique for providing data update information using metadata in which bibliographic items of data are described has been proposed. For example, when providing update information of a Web site, metadata called a feed described in accordance with an RSS (Rich Site Summary) format or an Atom format is used. The feed describes new arrival information in the website, the title of each article, the link destination (URL) of the website, the update date and time of the feed, and the like. When a user searches for a Web site of interest in advance and registers it in a feed reader (referred to as an RSS / Atom aggregator or RSS reader), the feed reader refers to the feed of the registered Web site, and updates information thereof To the user.

  However, in Patent Document 1, information provided to the user is limited to information registered in the server device. For this reason, despite the fact that there are various types of information available on the network, there has been a situation in which the user can only obtain information registered in the server device and cannot obtain sufficient information.

  In the technique using a feed, update information is provided only for a Web site or the like registered in advance in a feed reader. For this reason, the user needs to search for a website or the like that matches his / her interest and pre-register, and the provided update information is limited to the pre-registered website or the like. In addition, various information is described in the feed, and information that is not of interest to the user is often provided as update information. Further, when a plurality of websites are registered in the feed reader, update information is provided independently for each website, which is very complicated for the user.

  Therefore, an object of the present invention is that users do not have to search and register websites that match their interests in advance, and can collect metadata widely from the network, and integrate the collected metadata. It is an object to provide an information providing system and an information providing program that can be provided.

The information providing system of the present invention includes information acquisition means for acquiring input information input to the user interface and / or output information output to the user interface;
A keyword selection means for selecting the keyword by analyzing the input information and / or the output information, and one or more search engines that search for metadata available on the network and return metadata as a search result; Search request means for passing the keyword to search, detection data acquisition means for acquiring metadata detected by the search engine, and filtering for filtering the metadata acquired by the detection data acquisition means based on a predetermined condition And integration means for integrating the metadata after filtering by the filtering means to create integrated data,
The integrated data is provided to the user.

An information providing program of the present invention is an information providing program that causes a computer to function as an information providing system, and is an information acquisition step of acquiring input information input to a user interface and / or output information output to a user interface. ,
A keyword selection step of selecting the keyword by analyzing the input information and / or the output information, and one or more search engines that search for metadata available on the network and return metadata as a search result; A search request step for searching by passing the keyword, a detection data acquisition step for acquiring metadata detected by the search engine, and a filtering for filtering the metadata acquired by the detection data acquisition means based on a predetermined condition And a step of integrating the metadata after filtering by the filtering unit to create integrated data, and a step of providing the integrated data to a user.

  According to the present invention, for example, search information input to a user interface such as a Web browser, input information such as ULR, and / or news and blog output from a user interface such as a Web browser In order to acquire output information and select a keyword therefrom, a keyword reflecting the user's interest is automatically generated. When the keyword is passed to a search engine for searching, one or a plurality of search engines that search for metadata that can be used on the network and return the metadata as a search result match the user's interest. It is possible to collect information widely from the network. There is no need to search and register a site that matches your interest in advance. In order to acquire metadata detected by one or more search engines, filter the metadata according to predetermined conditions such as update date and deduplication, and provide the integrated metadata, one metadata is provided. Can be provided together. Since the integrated data is provided by starting the input / output of the user interface as a trigger, related information can be provided in real time while interlocking with the input / output of the user interface.

  Preferably, the integration unit / step extracts and integrates only the portion related to the keyword from each metadata after filtering by the filtering unit / step. According to this, since only the part related to the keyword is extracted and integrated, it is possible to provide only the related part to the user.

  The input information is input information input to a Web browser, the output information is output information output to a Web browser, and the integration unit / step extracts and integrates at least link information from each metadata It is preferable. According to the present invention, a keyword is selected from the input information and output information of the Web browser, and a search is performed based on the keyword. Therefore, metadata input to the Web browser and metadata related to the output information are transferred to the Web browser. Provided in conjunction with input and output. Since the provided integrated data includes link information described in each metadata, the user can easily obtain the data of interest by following this link.

  According to the information providing program and the information providing system according to the present invention, the user is interested in advance because one or more search engines that search for metadata that can be used on the network and return metadata as a search result are used. Information that matches interests can be obtained without searching for a website or the like and registering in advance. Since the information can be widely obtained from the Internet without being limited to the pre-registered data, it is possible to newly obtain information that matches the interest but has not been recognized. The detected metadata is integrated after being filtered under a predetermined condition and provided as integrated data, so that the user can obtain a plurality of detected metadata collectively. Since the process is started using the input / output of the user interface as a trigger, the user can obtain information related to the input information and output information in real time at a timing linked to the input and output of the user interface. If each metadata is provided to the user in the form of a list, the user can easily grasp all the information even if there are a plurality of metadata, and it becomes easy to find out information desired to know in more detail from the list.

  Further, if only relevant parts related to the keyword are extracted from the metadata after filtering and integrated, the user can obtain only the part of interest. If a keyword is selected from the input information and output information of the Web browser, the user can obtain integrated data related to the input information and output information in conjunction with the input and output timing of the Web browser. Since the integrated data includes link information included in the related portion, the user can follow these links to obtain data of interest one after another.

(First embodiment)
FIG. 1 is an explanatory diagram functionally explaining the information providing system Sys1 of the present invention. The information providing system Sys1 of the present embodiment is realized by the client terminal C. The information providing system Sys1 can be connected to one or a plurality of search engines E,. The network N is the Internet or the like, and the client terminal C is an information terminal such as a personal computer or a mobile phone.

  FIG. 2 is a block diagram showing a configuration of the information providing system Sys1 according to the embodiment of the present invention. The information providing system Sys1 according to the present embodiment is realized by a computer system. The communication interface 12, the CPU 13, the memory 14, the display 15, the keyboard / mouse 16, the drive 17, and the hard disk 18 are connected to the internal bus 11. It is configured to transmit an address signal, a control signal, data, and the like and function as the information providing system Sys1.

  The communication interface 12 has a function of connecting to the network N. For example, the communication interface 12 can communicate with other server devices including the search engine E, download various programs from other computer systems, and perform various communications. It is said. The CPU 13 controls the entire apparatus by an OS stored in a ROM that is a kind of the memory 14 and performs a function of executing processing based on the information providing program P and other application programs stored in the hard disk 18.

  The memory 14 is a storage unit such as a ROM, a RAM, or a cache memory. The ROM stores a program for controlling the entire apparatus, and has a function of supplying these to the CPU 13. The RAM is used as a work area when the CPU 13 executes various programs. The cache memory is a high-speed memory for eliminating a difference in processing speed between the CPU and various storage units, and may be incorporated in a part of the CPU 13.

  The display 15 is output means having a function of displaying text, images, and the like in accordance with various processes of the CPU 13. The keyboard / mass 16 is an input means including keys for inputting data such as characters, numbers, symbols, etc., a mouse for operating a point position on the screen, and the like.

  The drive 17 is a drive unit for executing an installation operation from a recording medium such as a CD or DVD in which various programs and data are recorded. It is also possible to install the information providing program P that causes the computer to function as the information providing system Sys1 from the storage medium.

  The hard disk 18 is an external storage device that stores the information providing program P, execution results, and the like. The information providing program P is installed from the communication interface 12 and the drive 17 described above, and is stored in the hard disk 18.

  The information providing system Sys1 includes an information acquisition unit 1, a keyword selection unit 2, a search request unit 3, a detection information acquisition unit 4, a filtering unit 5, and an integration unit 6. Each of these means is realized by an information providing program P that causes a computer to function as each means.

  The information acquisition unit 1 has a function of acquiring input information Iin input by the user and output information Iout output to the user in the client terminal C. The client terminal C includes an information input unit Bin that prompts the user to input input information Iin, an information output unit Bout that outputs information, and an information input / output unit Binout that prompts and outputs information. And a function to display on the display as an output column. The input information Iin input to the information input means Bin, the output information Iout output to the information output means Bout, and the input information Iin or output information Iout input to or output from the information input / output means Binout are stored in a storage means such as a cache memory. Remember. The information input means Bin, the information output means Bout, and the information input / output means Binout are preferably realized using a web browser that can have these functions in parallel. FIG. 3 is an explanatory diagram for explaining an example when a Web browser is used. When the input information Iin such as a keyword is input to the input field Bin of the Web browser B, the information acquisition unit 1 acquires the input information Iin and delivers it to the keyword selection unit 2. When output information Iout such as a Web page is output to the output field Bout of the Web browser B, the output information Iout is acquired and delivered to the keyword selection means 2. Further, when input information Iin such as URL is input to the input / output column Binout or output information Iout such as URL is displayed for a predetermined time, the input information Iin or output information Iout is acquired and keyword selection means is obtained. Hand over to 2.

  The input information Iin and output information Iout may be text information input to the user interface or text information output to the user interface, and are not limited to input / output to the Web browser. For example, input / output information of chat, e-mail, and Web site search application may be used. The information to be acquired may be either the input information Iin or the output information Iout. However, acquiring both pieces of information makes it easier to reflect the user's interest. Further, the information providing system Sys1 can communicate with a user interface such as a Web browser by using a function such as API (Application Programming Interface). For example, the information providing system Sys1 can display an input field Bin as a toolbar of the Web browser, Web browser input / output information can be acquired.

  The keyword selection unit 2 has a function of selecting one or more keywords k by analyzing the input information Iin and the output information Iout. The selection of the keyword k is performed according to the rules described in the information providing program P and stored in the hard disk 18. Although there are various rules, it is preferable that the rules more reflect the user's interest. For example, since the input information Iin is directly input by the user, it is considered that the user's interest is expressed with high probability. Therefore, the input information Iin may be selected as a keyword as it is. Since the output information Iout includes various information, weighting may be performed for each word according to the HTML tag, and the top several may be selected as keywords. The selected keyword k is stored in a storage unit such as the memory 14 or a hard disk. Note that the history, selection, and deletion of the selected keyword k may be set by the user. Alternatively, the selected keyword k may be displayed in the input field Bin so that the user can modify / delete / add it.

  When the search request unit 3 acquires the keyword k selected by the keyword selection unit 2, the search request unit 3 passes the keyword k to a plurality of search engines E,. It has a function to request. The search engine E is a computer system having a function of searching for metadata that can be used on the network N using the keyword k as a search target and returning the detected metadata as a search result. The search engine E to be used is set by default in the information providing system Sys1, or can be arbitrarily set by the user. When the search engine E receives the request from the search request means 3, the search engine E searches for metadata that can be used on the network N using the keyword k, and transmits the detected metadata D1,..., D1 to the information providing system Sys1. To do. The metadata is a bibliographic item (title, summary, update date / time, etc.) of each data that can be used on the network N, and is, for example, a feed described in an RSS format, an Atom format, or the like.

  When the detection data acquisition unit 4 receives the metadata D1,,, D1 detected by the search engine E from the search engines E,, E, the detection data acquisition unit 4 delivers the received metadata D1,,, D1 to the filtering unit 5. The acquired metadata D1,..., D1 is stored in a storage unit such as the memory 14. Note that the maximum number of metadata D1,..., D1 to be acquired may be set by the user, and the maximum number or less may be acquired from the metadata D1,.

  The search engine E may be realized by a server device connected to the information providing system Sys1 via the network N, but the information providing system Sys1 may have a partial function. When implemented by another server device, the search request unit 3 provides the input information Iin and output information Iout to the search engine E via the network N, and the detection data acquisition unit 4 includes the metadata D1,. D1 is acquired from the search engine E via the network N.

  The filtering unit 5 has a function of filtering the metadata D1, ..., D1 under a predetermined condition. By filtering, only metadata D2,..., D2 that meet a predetermined condition is extracted from the metadata D1,. Although the predetermined condition is arbitrary, for example, by referring to the tag of the update date / time included in the metadata, only the metadata whose update date / time is after the setting may be extracted, or a preset NG word may be Only metadata that is not included may be extracted. If the acquired metadata is duplicated, the duplicate may be eliminated. The detection data acquisition unit 4 and the filtering unit 5 are preferably prepared as independent modules for each search engine E, and can be easily customized according to the search engine E.

  The integration unit 6 has a function of integrating the metadata D2,... D2 filtered by the filtering unit 5. Since the metadata D2,..., D2 are individual files, the user feels very complicated when the metadata D2,. Therefore, the integration unit 6 integrates the metadata D2,..., D2 into one to generate integrated data D3. The integrated data D3 is preferably described so that the metadata D2, D2 is provided in a list format. Further, the metadata D2,... D2 may be rearranged in order of update date and time. The integrated data D3 is stored in a storage unit such as the memory 14 in a predetermined data format, but is preferably an RSS or Atom format feed so that it can be displayed by a general-purpose feed reader.

  Furthermore, it is preferable that the integration unit 6 has a function of extracting and integrating only the portion related to the keyword k from each metadata D2,. FIG. 4 is an explanatory diagram conceptually illustrating the function of the integration unit 6 that extracts and integrates only the relevant portions. Here, it is assumed that the selected keyword k is “Web 2.0”, and a portion related to the keyword k “Web 2.0” is extracted from each metadata D2,. Each metadata D2,..., D2 includes information that has nothing to do with the keyword k “Web2.0”, which is very redundant for the user. Therefore, the integration unit 6 extracts only the related portions d,... D related to the keyword “Web2.0” from the metadata D2,. The extraction of the related parts d,... D is performed as follows, for example. In accordance with the format of the metadata, the integrating means 6 includes a title t including the keyword k for each metadata D2,..., D2, an update date and time r, and a link (URL) u that can refer to information having the title. Extracted as d, and the extracted related parts d,. In addition, the site name, summary, etc. may be included.

  The integrated data D3 is output to the display 15 by the integrated data output means Dout and provided to the user. The integrated data output means Dout has a function of reading the integrated data D3 and outputting it to the display. For example, when the integrated data D3 is a feed in the RSS format or Atom format, the integrated data output means Dout is a general-purpose feed reader such as an RSS / Atom aggregator. FIG. 5 is an explanatory diagram for explaining a state in which the integrated data D3 is output by the integrated data output means Dout. The integrated data D3 is read into the integrated data output means Dout and displayed according to the format described in the integrated data D3. The metadata D2,..., D2 are arranged in a list format, and a title t and an update date r are displayed. Each title t has a link u to the extracted link destination (URL). When the title t is clicked, a new window is opened, and the link destination data is output to the output field Bout of the new window. In addition, new integrated data D3 is displayed so as to accompany it. In addition, a site name and a summary may be output. In this embodiment, the feed reader as the integrated data output means Dout is a ticker type, but it may be a built-in type incorporated in a browser or a mailer, or a stand-alone type that functions independently of a web browser or a mailer. Well, the form does not matter.

(Information provision program)
The information providing program P is a program in which instructions for causing the computer system to function as the respective means 1 to 6 are described, and includes the following steps. In addition, description is abbreviate | omitted about the same content as the description in the said system. FIG. 6 is a flowchart for explaining the information providing program P. (Step S1: Information acquisition step) Input information Iin and output information Iout are acquired. (Step S2: Keyword Selection Step) The keyword k is selected by analyzing the input information Iin and the output information Iout. (Step S3: Search Request Step) A search request is made by passing the keyword k to the search engine E. (Step S4: Metadata Acquisition Step) Metadata D1,... D1 is acquired from the search engine E. (Step S5: Filtering Step) Metadata D1,..., D1 is filtered to extract metadata D2,. (Step S6: Integration Step) Integrated data D3 is created by integrating the metadata D2,. It is preferable to extract and integrate only the related part d related to the keyword k from each metadata D2,. (Step S7: Provision Step) The integrated data D3 is stored in a storage unit such as a memory, and the integrated data D3 is output and provided to the integrated data output means Dout.

  The information providing program P may include a step of displaying an input field Bin for inputting the input information Iin before step 1, and the input field Bin is incorporated as a toolbar or the like when the Web browser is activated. It may be described so as to be displayed. Further, the information providing program P may include an instruction for causing the computer system to function as the search engine E. In that case, the next step S11 and step S12 are executed between step S3 and step S4. (Step 11) The keyword k selected in Step 3 is acquired, and a search using the keyword k is performed with metadata available on the network as a search target. (Step 12) The metadata D1,..., D1 detected by the search in Step 11 is stored in a storage unit such as a memory and transferred to Step 3.

(Usage mode 1)
Usage mode 1 is an example in which input information Iin of the user interface is used. The information providing system Sys1 realized by the information providing program P1 is used as follows. Using the user interface displayed on the display 15 of the client terminal C, the user inputs a keyword in the input field Bin or inputs a URL in the input / output field Binout. The information acquisition unit 1 acquires the input information Iin. The keyword selection unit 2 selects a keyword k from the acquired input information Iin, and the search request unit 3 delivers the selected keyword k to the search engine E to request a search. Upon receiving the request, the search engine E searches for metadata that can be used on the network N, and delivers the metadata D1,..., D1 detected as the search result to the detected data acquisition means 4. When the detection data acquisition means 4 receives the metadata D1,..., D1, the detection data acquisition means 4 stores the metadata D1,. The filtering means 5 filters the metadata D1,... D1 under a predetermined condition to extract the metadata D2,... D2, and the integrating means 6 integrates the metadata D2,. Generate. The integrated data D3 is output by integrated data output means Dout such as a feed reader. The user can obtain information of interest by referring to the integrated data D3 and following the link. As in the past, there is no need to search for a web site of interest and register it in the feed reader. Because it is provided from information available on the network without being limited to the registered site, etc., the user can obtain information widely, and information that was interested but could not be recognized is also new. Can be obtained as useful information. Since the integrated data D3 is provided in conjunction with the input / output of the user interface, the user can obtain information of interest in real time according to the input / output. The provided integrated data D3 is obtained by integrating a plurality of metadata, so that the user can see it as one. In particular, when only the relevant part d is extracted from the metadata D2,..., D2 and integrated, the user can see only the part of interest collectively. Since the integrated data D3 is in a list format, the user can easily select and refer to only necessary information from the list.

(Usage mode 2)
Usage mode 2 is an example in which output information Iout of the user interface is used. Using a user interface such as a Web browser displayed on the display of the client terminal C, the user inputs a URL in the URL input / output field Binout, and outputs data corresponding to the URL in the output field Bout. A portal site is displayed on the interface, a keyword is input in the keyword search input field of the portal site, and the search result is displayed in the output field Bout. The information acquisition unit 1 of the information providing system Sys1 acquires the output information Iout output to the output field Bout. The keyword selection means 2 selects the keyword k from the acquired output information Iout. Hereafter, it is the same as that of the said usage mode 1. The input / output column Iinout and the input information Iin may be acquired together with the output information Iout, and keywords may be selected from the output information Iout, the input / output information Iinout, and the input information Iin. According to this, the user can widely acquire information related to the information output to the user interface from the network without requiring registration. The user can obtain information related to the output information Iout in conjunction with the output of the user interface such as a web browser, and the information related to the output information Iout can be obtained by following the link displayed in the integrated data D3. You can get one after another.

(Second embodiment)

The information providing system Sys2 is realized by a computer system as shown in FIG. FIG. 7 is an explanatory diagram functionally illustrating the information providing system Sys2. The information providing system Sys2 can be connected to the client terminal C via the network N. The search engine E may be realized by a separate Web server, or may be realized as a partial function in the same server device S. When realized by a separate Web server, the information providing system Sys2 connects to one or a plurality of search engines E via the network N. Hereinafter, the same reference numerals are used for the same points as in the first embodiment, and the description thereof is omitted.

  The information providing system Sys2 provides the client terminal C with an interface having information input means Bin, information output means Bout, and information input / output means Binout. At the same time, a request for a return of identification information or the like that can identify the client terminal using a function such as HTTP cookie is also requested. The client terminal C outputs the information input means Bin, the information output means Bout, and the information input / output means Binout to an output means such as a display, and stores the input information Iin input thereto and the output information Iout output therein, such as a memory. The information is stored in the means and transmitted to the information providing system Sys2 via the network N. In addition, the identifier etc. which can identify the client terminal C are transmitted with the input information Iin and the output information Iout. When receiving the input information Iin, the output information Iout, the identifier of the client terminal C, and the like from the client terminal C, the information providing system Sys2 stores them in the storage unit such as the memory 14. The information acquisition unit 1 acquires input information Iin and output information Iout from the received information. The related part integration unit 6 from the keyword selection unit 2 generates the integration data D3 by the same processing as in the first embodiment. The information providing system Sys2 provides the generated integrated data D2 to the client terminal C based on the stored identifier, and causes the integrated data output means Dout to display it on the display 15 of the client terminal C.

  The user can collect widely metadata from the network N only by inputting and outputting information to the client terminal C. Since the information providing system Sys2 is realized by the server device, the load on the client terminal can be suppressed.
