[Server device 3]
As shown in FIG. 2, the server device 3 includes, for example, an I / F unit 11, a memory 12, and a processing unit 13, which are connected via a data line 10.
The I / F unit 11 exchanges data with the database 2 and the computer 4.
The memory 12 stores various data such as a program PRG1 executed by the processing unit 13, and table data TABLE and metadata META used for processing of the processing unit 13.
The processing unit 13 executes the program PRG1 stored in the memory 12 and causes the display unit of the computer 4 to display a search condition input screen for the paper data Thesis and a search result screen.

In the present embodiment, the server device 3 uses the location data place for each of the affiliation data companies of the authors of the paper data Thesis stored in the database 2 before the search for the paper data Thesis. And latitude / longitude data la-lo are acquired and stored in the memory 12 as table data TABLE.
Further, as illustrated in FIG. 4, the processing unit 13 of the server device 3 generates and stores in the memory 12 the title of the paper, contribution date data indicating the date on which the paper was contributed, and metadata META indicating the attribute relating to the author. The article data Thesis stored in the database 2 is managed based on the metadata META.

The processing unit 13 generates metadata META for each paper data Thesis stored in the database 2 using, for example, RDF (Resource Description Framework).
RDF is a language for describing metadata based on XML (eXtensible Markup Language).
RDF is used to describe a data model that allows a chain of relationships to be traced by three relationships: subject (resource), predicate (property), and object (object, property value).
RDF is composed of two specifications: Model and Syntax (RDFS) that defines the structure and syntax of RDF itself, and a schema that defines the vocabulary of metadata.

Hereinafter, an outline for describing the metadata META in RDF will be described with reference to FIG.
That is, as illustrated in FIG. 4, the processing unit 13 defines a class “rdfs: Resource” that is a base class.
Here, everything expressed in RDF is a resource, and is defined as a subclass of the class “rdfs: Resource”.
Also, the class “document” shown in FIG. 4 is defined as a derived class of the class “rdfs: Resource”, which is the parent class, by the property “rdfs: subClassOf”. Derived classes inherit the properties of the parent class.
The class “Thesis (paper)” is defined as a derived class of the class “document” which is the parent class by the property “rdfs: subClassOf”.
Further, the article data “A” as a specific resource is defined as a member (instance) of the class “Thesis” by the property “rdfs: type”.

Further, a literal (character string) “A title” indicating the title of the paper is defined by using the paper data “A” as a resource and Dublin Core “dc: title” as a property.
Also, a literal (character string) “2003/4/15” indicating the contribution date of the paper is defined with the paper data “A” as a resource and Dublin Core “dc: date” as a property.
Further, the resource “a” (author data) of the author of the paper is defined by using the paper data “A” as a resource and Dublin Core “dc: creator” as a property.
Further, the author's resource “a” is a resource, “Rdfs: Literal” is a property, the author's name data “name”, an electronic mail address “e-mail”, affiliation data “company”, and title data “title”. The book data “papers” is defined.

  Further, the resource “METAa” of the metadata METAa indicating the keyword of the content related to the paper is defined by using the paper data “A” as a resource and Dublin Core “dc: description” as a property.

Hereinafter, the search process of the paper data Thesis by the server device 3 will be described.
For example, in response to a search request from the computer 4, the processing unit 13 of the server device 3 searches for the paper data Thesis corresponding to the keyword specified in the search request based on the metadata META of the paper data Thesis.
Then, the processing unit 13 extracts the affiliation data company of the author of the retrieved paper data Thesis, and identifies the latitude / longitude data la-lo corresponding to the affiliation data company from the table data TABLE shown in FIG.
Then, the processing unit 13 uses the date of contribution of the paper extracted from the paper data Thesis and the latitude / longitude data la-lo specified above to determine the contribution location of the paper data Thesis related to the theme used as the keyword. Display data for displaying an image showing a time transition is generated.
The processing unit 13 outputs the display data to the computer 4 via the I / F unit 11.
For example, the processing unit 13 generates display data that causes the computer 4 to display the screens 50a and 50b illustrated in FIG.
The screens 50a and 50b have contribution date display fields 51a and 51b indicating the contribution date of the retrieved paper data Thesis 1 and 2.

The screens 50a and 50b have a cursor image 52 for the user to designate a contribution date by operating with an operation unit such as a mouse of the computer 4.
The screens 50a and 50b have a map image 55, and mark images 53a and 53b indicating the location of the institution to which the authors of the paper data Thesis 1 and 2 belong on the map image.
When the user moves the cursor image 52 (changes the contribution date), the mark image 53a moves from the mark image 53a to the mark image 53b indicating the location of the institution to which the author of the article data Thesis on the contribution date belongs.
In the example of FIG. 5 described above, a case where one paper data Thesis is searched on the same contribution date is illustrated. However, when a plurality of paper data Thesis is searched on the same contribution date, for example, as illustrated in FIG. As described above, the processing unit 13 generates display data for displaying a plurality of mark images 53c according to the number of the paper data Thesis.
In addition, when one or a plurality of paper data Thesis is searched from the same place or a place within a predetermined range, the processing unit 13 displays a mark image having a color or density corresponding to the number of searched paper data Thesis. Is generated at a corresponding position on the map. For example, the processing unit 13 generates screen display data in which the color density of the mark image increases as the number of retrieved paper data Thesis increases.
In addition, the processing unit 13 uses a convex image such as a mountain as the mark image, and generates display data for a screen in which the height of the convex shape is increased according to the number of retrieved paper data Thesis. May be.

In response to a request from the computer 4, for example, the processing unit 13 generates display data of a screen 60 including a detailed map image of the location of the affiliated organization as illustrated in FIG. 7 from the screen 50a illustrated in FIG. May be.
Further, in response to a request from the computer 4, the processing unit 13 may generate display data of a screen 61 that simultaneously displays the marks 53a and 53b on a map, as in a screen 53a shown in FIG. .

Step ST2:
The processing unit 13 extracts the affiliation data company of the author of the paper data Thesis based on the metadata META shown in FIG. 4 corresponding to the paper data Thesis.
Step ST3:
The processing unit 13 determines whether or not the table data TABLE is to be updated. If it is determined that the update is unnecessary, the process proceeds to step ST7. If it is determined that the update is necessary, the process proceeds to step ST4.
Specifically, the processing unit 13 determines that the update of the table data TABLE is unnecessary when the item corresponding to the affiliation data company extracted in step ST2 is present in the table data TABLE, and if the item does not exist, the table 13 It is determined that the data table needs to be updated.

Step ST4:
The processing unit 13 acquires the location data place indicating the location of the organization indicated by the affiliation data company extracted in step ST2 by accessing a predetermined server device via data held by the server device 3 or a network, for example.
The location data indicates, for example, an address.
Step ST5:
The processing unit 13 generates latitude / longitude data la-lo indicating the latitude and longitude of the address indicated by the location data place acquired in step ST4.
Step ST6:
The processing unit 13 is a table shown in FIG. 3 showing items indicating the affiliation data company extracted in step ST2, the location data place generated in step ST4, and the latitude / longitude data la-lo generated in step ST5 in association with each other. Append to data TABLE.
Step ST7:
The processing unit 13 determines whether or not the update process of the table data TABLE has been completed with respect to an end condition, for example, predetermined paper data Thesis. If it is determined that the process has ended, the process ends. The process of step ST1 is performed on the paper data Thesis.
Note that, when a plurality of author data is associated with a single paper data Thesis, the processing unit 13 performs the processing of steps ST2 to ST6 for each of the belonging data companies corresponding to the plurality of author data.
