Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document delivery system for searching and delivering a character string in a document via a network, and more particularly to a document delivery system capable of quickly displaying a sentence including the searched character string.

[0002]

2. Description of the Related Art When a client and a server connected via a network such as the Internet search and display a document including a specific character string, the server specifies a document file including the relevant character string. , From the end of the document file (at the beginning or end). The viewer scrolls the document received from the server on the screen of the client to sequentially switch the display, thereby searching for a desired portion.

[0003]

In the above prior art, even if the document including the corresponding character string is long, the document is distributed and displayed in order from the beginning (or the tail) of the document. It was very troublesome to identify. In particular, when it takes time to distribute data to the client due to a reason such as a low data transfer speed of the network, the viewer feels very strong discomfort.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and provides a document delivery system that allows a viewer to quickly and easily check a search result when displaying a document including a searched character string. The purpose is to provide a system.

[0005]

In order to solve the above-mentioned problems, a document distribution system according to a first aspect of the present invention comprises:
The server is configured to include a server and a client connected to each other via a network, and the server searches for and delivers a document including a search character string requested by the client. An input unit configured to input the search character string; a transmission / reception unit configured to transmit the search character string input by the input unit and receive a document from the server; and a document received by the transmission / reception unit from the server. Display position defining means for defining the display position of each sentence, and display means for displaying a document in which the display position defining means defines the display position of each sentence, wherein the server has storage means for storing a document; Searching for the search string received from the client in a document stored by the storage unit, and specifying a document including the search string Searching means, and when distributing the document specified by the searching means, first distributes a sentence including the search character string in the document, and then distributes the sentence closest to the first distributed sentence in order. And processing means comprising means.

In such a configuration, when distributing the document including the search character string, the server distribution means distributes the document including the search character string in the document in order from the document, and the display position defining means of the client. Can define the display position of each sentence and display it on the display means. Thus, when the viewer checks the search result, the sentence including the search character string can be displayed, and the search result can be easily checked.

[0007] The processing means includes a scoring means for scoring each sentence in the document including the search character string in accordance with the result of the search by the search means, and the storage means comprises: Score storage means for storing a score assigned to each sentence in association with the position of each sentence, wherein the delivery means determines a delivery order of each sentence based on the score given by the scoring means, and stores the score in the score storage means. Information indicating the stored score of each sentence and the position of each sentence is added to each sentence and distributed, and the display position defining means specifies the position of each sentence based on the information added to each sentence by the distribution means. It is preferable that the document has the same configuration as the document stored by the storage means, and the display position of each sentence is specified so that the sentence including the search character string delivered first by the server is displayed first. . Thus, even if the distribution means of the server determines the distribution order of each sentence irrespective of the arrangement in the original sentence, the display position defining means of the client defines the arrangement of each sentence and displays the same arrangement as the original sentence. Can be.

[0008] The scoring means assigns the highest score such as "10" to the sentence including the search character string,
As the distance from the sentence with the highest score increases, for example, a score decremented by "1" is assigned to each sentence, and the distribution unit assigns the sentence to which the scoring unit gives the highest score. May be delivered first as a sentence serving as a reference for delivery, and sentence may be sequentially delivered from a sentence closer to the sentence that was first delivered.

[0009] The scoring means assigns a higher score to a sentence containing a connecting word having a meaning to put together the preceding sentence, for example, a sentence including the search character string, such as “ie” or “in short”. It may be. This allows
The distribution means of the server can distribute from the sentence that will have more important meaning in the document, and can increase the possibility that the search result displayed by the display means of the client is what the viewer desires.

When the distribution unit receives a distribution request for the next sentence from the client during the distribution of the document, the scoring unit assigns the highest score to the sentence which is the last sentence. After specifying the sentence on the side and delivering the specified sentence with priority, the sentence closer to the specified sentence may be sequentially delivered. Thereby, when the search result is not what the viewer desires, the next search result can be quickly distributed and displayed, and the search result can be easily confirmed.

[0011] The input means includes an instruction means for instructing that the sentence displayed by the display means be limited to a sentence having a score equal to or higher than a predetermined score. Read the information added to each sentence,

Thereby, it is possible to prevent a sentence apart from the sentence including the search character string from being displayed, and the viewer can more easily check the search result.

[0012] The distribution means may distribute a sentence having a score equal to or higher than the score designated by the designation means. As a result, at the time of retrieval, the amount of sentence can be reduced and the addition of a network can be reduced.

A document delivery server according to a second aspect of the present invention includes a storage unit for storing a document, a reception unit for receiving a search character string from a client, and a storage unit for storing the search character string in the storage unit. A search unit that searches the search string received by the reception unit and identifies a document that includes the search string; and a search request that distributes the document that includes the search string from a client. And a delivery unit that first delivers a sentence containing the search character string in the contained document and delivers the sentence closer to the sentence containing the search character string in order. .

A document distribution method according to a third aspect of the present invention is a method for distributing a document including a search character string from a server to a client, wherein the document including the search character string is included in the document. Identify the sentence containing the search string, deliver the identified sentence first, deliver the sentence closer to the sentence first, and display the sentence containing the search string first. And displaying a document including the search character string. Thus, the viewer can quickly check the sentence including the search character string, and can easily check the search result.

[0015] Since the order of the sentence distributed by the server is determined irrespective of the arrangement of the documents stored in the storage means, when distributing the document including the search character string, information indicating the position of each sentence is provided. It is desirable to add and distribute.

The communication unit 22 includes a line terminating device such as a modem connected to the network 300, and
00 for transmitting and receiving data.

The operation of the document distribution system according to the embodiment of the present invention will be described below. This document distribution system is for distributing and displaying sentences in a sequence starting from a sentence including a search character string input by a viewer, thereby enabling quick confirmation of search results.

[0036] The viewer is the input unit 1 of the client 100.
The homepage can be browsed by, for example, clicking on an icon of the browser software using the mouse provided in the server 4, and accesses the page of the search service provided by the server 200.

When the processing section 20 of the server 200 receives the access from the client 100, the processing section 20 starts the processing shown in the flowchart of FIG.

The processing unit 20 extracts screen data for inputting a character string to be searched from the storage unit 21 and transmits the screen data from the communication unit 22 to the accessed client 100 via the network 300.

The CPU 10 of the client 100 receives the screen data from the server 200, and displays an input screen D1 as shown in FIG. 10 on the display unit 13 (Step S).
100). The input screen D1 includes an input field R1 for inputting a search character string and a button B1 for instructing a search.

The CPU 10 waits until a search character string is input in the input field R1 and the button B1 for instructing a search is clicked (NO in step S101). The viewer inputs a search character string using a keyboard provided in the input unit 14,
The user instructs a search by clicking a button B1 for instructing a search with the mouse of the input unit 14.

When the CPU 10 of the client 100 determines that the button B1 for instructing a search has been clicked in step S101 (YES), the communication unit 15 sends the server 2
Send the search string to 00. Processing unit 2 of server 200
0 receives a search string from the client 100,
The search process shown in the flowchart of FIG. 7 is started (step S102).

When the search unit 20 starts the search processing, the search processing unit 30 searches for a search character string in the document stored in the document storage unit 40 (step S200).

When finding the corresponding character string (YES in step S201), the search processing unit 30 registers the file name of the document file containing the search character string in the file index 50 and stores it in the file index storage unit 41. (Step S202).

On the other hand, the search processing unit 30 determines in step S20
If it is determined in step 1 that the corresponding character string cannot be found (N
O), jump to step S203 and continue the process.

The search processing unit 30 determines whether all documents stored in the document storage unit 40 have been searched (step S203).

If the search processing unit 30 determines that all the documents have not been searched in step S203 (NO), the process returns to step S200 to continue the search.

On the other hand, the search processing unit 30 determines in step S20
If it is determined in step 3 that all documents have been searched (YES), a notification to transmit the file index 50 is sent to the distribution processing unit 32, and the search processing ends.

Thereafter, the process proceeds to step S103 in FIG. 6, where the distribution processing unit 32 receives the notification from the search processing unit 30 that the file index 50 is to be transmitted, and stores the file index stored in the file index storage unit 41. 50 is read and transmitted to the client 100.
The CPU 10 of the client 100 reads the received file index 50 and outputs the document file name to the display unit 13 by linking each document file name with each document file itself according to the address of the document described in the item “URL” of the file index 50. .

The CPU 10 of the client 100 waits until the document file displayed on the display unit 13 is selected (NO in step S104), and when the document file is selected (YES), the server 200 selects the document. Report the file name. The processing unit 20 of the server 200 receives the notification of the document file name from the client 100 and
The document distribution process shown in the flowchart of (1) is started (step S105).

When the processing section 20 of the server 200 starts the document distribution processing, the search processing section 30
The document file notified from 0 is searched, and a notification that the search data table 51 is created is sent to the dot processing unit 31. The score processing unit 31 adds the highest score to a sentence including the search character string based on the result of the search processing unit 30 searching the document file, and deducts points according to the distance from the sentence (how many sentences are apart). A score is attached to each sentence, registered in the search data table 51 in association with the position of each sentence, and stored in the search data table storage unit 42 (step S30).
0).

The search processing section 30 sends a notification to the delivery processing section 32 that the document file is to be delivered. Delivery processing unit 32
Reads the search data table 51 stored in the search data table storage unit 42, and specifies the sentence with the highest score near the beginning of the document as a reference sentence (step S301).

The delivery processing unit 32 extracts the document related to the delivery from the document storage unit 40, and the sentence assigned the highest score specified in step S301 (the sentence serving as a reference for delivery).
Are distributed first, and then the sentences are distributed in order from the sentence that is close to the reference sentence. At this time, the CPU 20 adds data indicating the score of each sentence and the position of the sentence shown in the search data table 51 (numerical values described in the items “start” and “end”) to each sentence as display information data. And deliver.
Thereby, even if the order of distributing each sentence is determined irrespective of the arrangement of the sentences, the arrangement of each sentence can be defined on the client side and displayed as the same configuration as the original sentence.

The CPU 10 of the client 100 reads the display information data added to each received sentence so that the sentence has the same structure as the original sentence, and the sentence first sent by the server 200 (the sentence serving as a reference for delivery). Is displayed first, the display position of each sentence is defined so as to be displayed on the display unit 13, and the document distribution process ends (step S <b> 30).
2). Thus, the sentence including the search character string can be displayed quickly, and the viewer can quickly confirm the search result.

When the client 100 receives the document distribution and sequentially displays the document (step S30 in FIG. 8).
When the viewer instructs the display of the next sentence by the input unit 14 during the execution of (2), the distribution request for the next sentence is sent to the server 200. Upon receiving the distribution request for the next sentence, the search processing unit 30 of the server 200 starts the interrupt distribution processing shown in the flowchart of FIG. 9 and sends a notification to the distribution processing unit 32 to distribute the next sentence.

Upon receiving the notification from the search processing unit 30 that the next sentence is to be delivered, the delivery processing unit 32 reads the search data table 51 (step S400). Delivery processing unit 32
Determines whether there is a sentence with the highest score at the end of the sentence from the sentence with the highest score, which is currently the reference for distribution (step S401). When the distribution processing unit 32 determines that there is a sentence with the highest score at the end of the sentence (YES in step S401),
The sentence having the highest score is sent to the client 100 as a sentence serving as a new reference for delivery, and then sent in order from the sentence closest to the sentence (step S402).

The CPU 10 of the client 100 reads the display information data added to each received sentence,
The documents are arranged according to the configuration of the document, and are sequentially displayed on the display unit 13 from a sentence serving as a new reference for distribution. Thus, the viewer can quickly grasp the search result and display the next search result.

On the other hand, the distribution processing unit 32 determines in step S40
If it is determined in step 1 that there is no sentence with the highest score at the end of the sentence (NO in step S401), the client 100 is notified that the next candidate cannot be found. C of client 100
The PU 10 receives the notification from the server 200 that the next candidate is not found, notifies the viewer by displaying an error display such as “the next candidate is not found” on the display unit 13, and performs an interrupt distribution process. (Step S4)
03).

The processing section 20 of the server 200 continues transmitting each sentence until all the documents requested for distribution can be transmitted, and when all the transmissions are completed, the processing shown in FIG. 6 ends.

As described above, according to this document distribution system, when distributing a document including a search character string,
It is possible to preferentially distribute and display a sentence including a search character string input by a viewer. As a result, the search result can be easily checked, and the sentence including the character string to be searched can be quickly checked.

The present invention is not limited to the above embodiment, and various modifications and applications are possible. For example, in the above-described embodiment, sentences that are close to the highest-scored sentence are sequentially distributed and displayed, and the manner of displaying each sentence by score is not specified, but the present invention is not limited to this. That is, instead of the input screen D1 shown in FIG. 10, an input screen D2 as shown in FIG. 11 is provided, and an input field R2 for inputting a score of a sentence to be displayed is provided. Only sentences with scores equal to or higher than the score may be displayed. In this case, step S3 in FIG.
In 02, the CPU 10 of the client 100 reads the score of the sentence received from the server 200, and displays each sentence so that only the sentence higher than the score input in the input field R2 of the input screen D2 is displayed on the display unit 13. / Hide may be switched.

Further, the distribution processing unit 32 of the server 200
However, the network load can also be reduced by distributing only sentences with a score equal to or higher than the score input in the input field R2 of the input screen D2. In this case, when receiving the search character string from the client 100, the search processing unit 30 also receives the score input to the input field R2 and notifies the distribution processing unit 32. Then, when distributing the document, the distribution processing unit 32 only needs to read the search data table 51 and distribute only a sentence with a score equal to or higher than the score input in the input field R2.

In the above embodiment, the dot processing unit 3
1 is described as that a sentence including a search character string is assigned the highest score and registered in the search data table 51 regardless of the context of the document searched by the search processing unit 30.
It is not limited to this. That is, in the document, a sentence having a connecting word having a meaning to put together the preceding sentence, such as “that” or “in short,” including a search character string, is assigned a higher score and registered in the search data table 51. Is also good. By doing so, the viewer can preferentially browse the sentence that will have more important meaning in the document, and it is possible to increase the possibility that the search result is what the viewer desires.

According to the present invention, any computer connected to a network can be used as a client or a server, without using a dedicated client and server.
For example, a program for executing a part of each of the above processes performed by each computer (or a group of computers) is stored in a recording medium and distributed, and each corresponding part of the program is transferred to a computer and installed. OS
By executing above, a computer (or group of computers) can be used as a client or a server.

[0063]

As described above, according to the present invention, when a document including a search character string is distributed, a sentence including the search character string can be preferentially distributed and displayed. This allows the viewer to quickly check the search results.
