DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a fitness order image enhancement display device according to the present invention. The image data with text input unit 1, the keyword extraction unit 2, the keyword importance evaluation unit 3, and the search keyword input unit. 4, a retrieval intention conformance degree calculation unit 5, a retrieval intention conformance degree order sorting unit 6, an image display frame size determination unit 7, and a retrieval intention conformance degree corresponding image display unit 8.
As hardware, each of these units is configured by a so-called computer and shares a storage device, but is omitted in FIG. 1.

The text-added image data input unit 1 inputs a data set consisting of image data and text data accompanying it to a storage device. Generally, there are multiple data sets. The keyword extraction unit 2 is a unit that automatically extracts a plurality of keywords (referred to as a content keyword group) representing the contents written in the text from the text data unit of each data set, and evaluates the keyword importance. The unit 3 evaluates and calculates the importance of each content keyword of the extracted content keywords in the text, adds the importance to each content keyword, and generates a content keyword group with importance. It is a part. The search keyword input unit 4 is a keyboard or the like through which a searcher inputs a keyword group for search (referred to as a search keyword group). The search intention conformity calculation unit 5
For each data set, the content keyword group with importance is compared with the search keyword group, and the search intention for the search keyword group of each data set is used by using the number of matching keywords and the importance of matching keywords. The part for calculating the goodness of fit, the search intention goodness-of-order sort unit 6 arranges the data set in the order of the search intention goodness of fit, and the image display frame size determination unit 7 makes This is a part for determining the size of an image frame when displaying image data in a data set. The image display unit 8 corresponding to the search intention adaptability is a unit that displays a plurality of image data with different sizes on the screen based on the determined display frame size when displaying image data.

FIG. 3 is an example of the image display according to the present invention, in which a plurality of image data items to be searched are displayed in order from large to medium and then to small according to the degree of search intention conformity. Is shown. As a result, the searcher only has to look from the large display in order, and the burden on the search is greatly reduced.

4 to 6 show an operation example of this embodiment. Here, 110 is an image data input unit with text 1
Input processing by 120, processing by the keyword extraction unit 2, 130 by the keyword importance evaluation unit 3, 1
40 is input processing by the search keyword input unit 4, 15
0 is a process by the search intention conformity calculation unit 5, 160 is a process by the search intention conformance order sorting unit 6, 170 is a process by the image display frame size determining unit 7, and 180 is a search intention conformance image display unit 8. This is a display process.

First, a text-attached image data input process 1
By 10, a plurality of image data with text (data set) is input. Here, the input data set is A to N. The result of inputting image data with text is indicated by 210.

Next, the keyword extraction processing 120 extracts keywords from the text portions of the input data sets A to N. Each of the extracted keywords is added to the data set as attribute information. The result of this keyword extraction processing is shown at 220.

Next, the keyword importance evaluation processing 130 evaluates the importance of each keyword in each of the data sets A to N. Here, as to the importance of the keyword, as described in, for example, Japanese Patent Laid-Open No. 1-131331, the appearance position and appearance frequency of the keyword in the text, or refer to an important word dictionary prepared in advance, etc. And evaluate. The evaluated importance is represented by, for example, a numerical value and added to the keyword. The result of this keyword importance evaluation processing is shown at 230.

On the other hand, a searcher inputs a search keyword from an input device such as a keyboard in a search keyword input process 140. The search keyword input result is indicated by 240.

Next, the retrieval intention conformance calculation processing 150 compares the content keyword group with importance with respect to each of the data sets A to N and the retrieval keyword group, and determines the number of matching keywords and the matching keywords. Using the degree of importance and the like, the degree of matching of the search intention to the search keyword group of each data set is calculated. The suitability is added as an attribute to each data set. The result of this retrieval intention matching degree calculation processing is shown at 250.

The following are a few examples of how to obtain the search intent suitability. Now, the content keyword group with importance in the data set i (hereinafter referred to as set Φ) is {K
_Let W _i1 , KW _i2 , ..., KW _im }, and the importance of each keyword be α _i1 , α _i2 , ..., α _im . In addition, a search keyword group (hereinafter referred to as a set Ω) is {KW _j1 , K
_Let W _j2 , ..., KW _jn }.

The first method is to use the sum of the keyword importance of the matched keywords between the set Φ and the set Ω as the retrieval intention matching degree (R ₁ ). That is,

[0020]

[Equation 1]

The second method is to retrieve the product of the ratio of the number of matching keywords (set as p) between the set Φ and the set Ω to the total number of elements (total number of keywords) of each set. It is a goodness of fit (R ₂ ). That is,

[0022]

[Equation 2]

The third method is to obtain the product of R ₁ and R _{2 in} the above equations (1) and (2) as the retrieval intention matching degree (R ₃ ). That is,

[0024]

(Equation 3)

Next, the retrieval intention matching degree order sort processing 160
According to, the sorting process is performed on the set of data sets in the order of search intention conformity. The result of this sort of search intention matching degree sorting is shown at 260. This is an example in which the data sets A to N are rearranged in the order of N, A, ..., B assuming that the data set N is the largest and the data set B is the smallest in the search intention matching degree.

Next, the image display frame size determination processing 170 determines the size of the image display frame according to the degree of the search intention adaptability. The size of the image display frame is also added to each data set as attribute information. A result 270 of the image display frame size determination processing is shown.

Next, the image display processing 1 corresponding to the retrieval intention conformity degree
By 80, the image display is performed on the data set in the sort order by the above processing 160 based on the image display frame size. A result 280 of the image display processing corresponding to the retrieval intention conformity degree is shown. If all the images to be searched cannot be displayed on one screen at one time, they may be displayed across a plurality of screens.

As indicated by reference numeral 280 in FIG. 6, the image information to be searched can be easily searched by displaying the images to be searched in a large or small order in accordance with the degree of matching with the search request of the searcher. Therefore, it is possible to improve the search efficiency and significantly reduce the burden on the searcher during the search.

[0029]

As described above, according to the fitness order image enhancement display method and apparatus of the present invention, the degree of suitability to the search request of the searcher when the image to be searched is displayed on the screen. Depending on the size of each image, it is easy to see by displaying each image in big and small,
It is possible to improve the search efficiency and significantly reduce the burden compared with the case where the searcher has to search for only the desired image from the image groups that are uniformly displayed at the time of searching as in the conventional case.
