20160203147
The present invention relates to technology of a page/site server disclosing Web pages.
This application claims the benefit of priority under the Paris Convention from Japanese patent application No. 2013-196454, filed on Sep. 24, 2013, which is incorporated herein by reference in accordance with PCT rule 20.6.
In recent years, a huge amount of Web page contents are disclosed through the Internet by page/site servers. The page contents are pages which many and unspecified third parties can access and which in most cases include text sentence(s)/document(s). A terminal accesses the page/site server and displays a part or (if possible) a whole of the obtained page content with a browser. The user of the terminal can browse the displayed page then to change the display range by scrolling (page-up/page-down).
Meanwhile, many and unspecified users contribute through the Internet an enormous amount of comments to site servers which process, e.g. SNS (Social Networking Service), blog (weblog) or mini blog (mini weblog) such as Twitter (registered trademark). There are many cases in which the posted comments discuss a common topic. For example, there contributed are many comments that discuss, as the common topic, the content of a page content as above-described.
There are conventional technologies which facilitate browsing of information sites which exist on networks. For example, Patent Document No. 1 discloses a technique in which automatically extracted from many information sites and displayed is an information that has a high possibility of being required by a user. The technique extracts a main body text of a title or article from each of the pre-registered information sites and preferentially provides information of information sites that carry main body texts similar to one another. When a desired information (title) is focused, its main body text is read out and pop-up displayed.
Also, Patent Document No. 2 discloses a technique where, by analyzing tags of HTML (HyperText Markup Language) in blog sites, only main bodies described by users are extracted from the blog sites. Further, Non-patent Document No. 1 discloses a technique which extracts descriptions related to the future by analyzing the structure of sentences of Web news, and then automatically arranges the extracted information in the form of a chronological table.
The conventional technique described in Patent Document No. 1 is designed to display on a terminal the whole of important news articles reported on plural information sites. The conventional technique described in Patent Document No. 2 is intended to display on a terminal only main bodies obtained by excluding such as advertisements and banners from Web pages. Further, the conventional technique described in Non-patent Document No. 1 is designed to display on a terminal a summary text generated by extracting portions described on a predetermined viewpoint from a news article and then summarizing the portions.
All of the above-mentioned conventional techniques require users to browse a part of the page content displayed through a browser and then change the display range by scrolling thereby to search an noteworthy sentence. If the noteworthy sentence appears at the end of the page content, the users have to scroll the page content from the head to the end.
Here, the present inventors focus on prompt display of a noteworthy place which interests every user in a page content. Especially in the case of using a terminal such as a smartphone or a tablet-type computer, it is more difficult to promptly display such a noteworthy place because of the restriction of the display size even according to the above-described conventional techniques.
It is therefore an object of the present invention to provide a page/site server, a program and a method for immediately displaying a noteworthy place which interests every user in a page content.
According to the present invention, there provided is a page/site server which enables communication with a comment server allowing plural contributors to send their comments to one another and responds with a page content including text according to a page acquisition request transmitted from a terminal, the page/site server comprising:
a comment group retriever retrieving from within the comment server a comment group related to the page content;
a characteristic word extractor extracting from the comment group a characteristic word that appears in text of the page content with a high appearance frequency under a predetermined condition;
a characteristic word retriever retrieving a place where the characteristic word appears in the page content; and
a browsing-part display controller controlling the objective page content to be displayed on the terminal in such a way that the place where the characteristic word appears can be browsed.
As an embodiment of the page/site server according to the present invention, it is preferable that the characteristic word extractor uses TF-IDF (Term Frequency-Inverse Document Frequency) method to extract from the comment group one or more characteristic words characterizing the page content as distinguished from the other ones.
As another embodiment of the page/site server according to the present invention, it is also preferable that the browsing-part display controller displays a page part including the characteristic word of the page content at a top or center of a display area of the terminal, or by direct jump to the top or center.
As another embodiment of the page/site server according to the present invention, it is also preferable that the browsing-part display controller highlights the characteristic word of the page content.
As another embodiment of the page/site server according to the present invention, it is also preferable:
that the page/site server further comprises a concept dictionary holding an information describing a conceptual system and outputting a generalized word as a broader concept word of an inputted word; and
that the characteristic word extractor extracts a plurality of characteristic words then to convert the characteristic words into generalized words by using the concept dictionary and thus to output the generalized word with a high appearance frequency as a characteristic word.
As another embodiment of the page/site server according to the present invention, it is also preferable that the page content is a content of a news article, and that the comment is transmitted from an SNS (Social Networking Service) server, a blog (Web-log) server, a bulletin board server or a review site server.
According to the present invention, there provided is a proxy server which enables communication with a comment server allowing plural contributors to send their comments to one another and with a page disclosing server disclosing page contents including text, forwards to the page disclosing server a page acquisition request received from a terminal, and then forwards to the terminal the page content received from the page disclosing server, the proxy server comprising:
a comment group retriever retrieving from within the comment server a comment group related to the page content;
a characteristic word extractor extracting from the comment group a characteristic word that appears in text of the page content with a high appearance frequency under a predetermined condition;
a characteristic word retriever retrieving a place where the characteristic word appears in the page content; and
a browsing-part display controller controlling the objective page content to be displayed on the terminal in such a way that the place where the characteristic word appears can be browsed.
According to the present invention, there provided is a program to be executed by a computer mounted on a page/site server which enables communication with a comment server allowing plural contributors to send their comments to one another and responds with a page content including text according to a page acquisition request transmitted from a terminal, the program causing the computer to function as:
a comment group retriever retrieving from within the comment server a comment group related to the page content;
a characteristic word extractor extracting from the comment group a characteristic word that appears in text of the page content with a high appearance frequency under a predetermined condition;
a characteristic word retriever retrieving a place where the characteristic word appears in the page content; and
a browsing-part display controller controlling the objective page content to be displayed on the terminal in such a way that the place where the characteristic word appears can be browsed.
According to the present invention, there provided is a page disclosing method executed in a page/site server which delivers page contents and enables communication with a comment server allowing plural contributors to send their comments to one another, the page disclosing method comprising:
a first step of retrieving from within the comment server a comment group related to the page content;

Especially in the case of using a terminal such as a smartphone or a tablet-type computer, the page/site server, the program and the method facilitate browsing the noteworthy place without being affected by the restriction of the display size.
The drawings are presented in which:
Illustrative embodiments of the present invention will be described below with reference to the drawings.
As shown in
The page/site server 1 is configured to deliver a page content in which an noteworthy place to be observed is prepared to be displayed immediately with scrolling the page. The page content is a content which can be accessed by many and unspecified users and includes text(s) such as a news article.
The comment server 2 is a site server which enables plural contributors to send their text comments to one another. The server 2 may be, for example, an SNS (Social Networking Service) server, a blog (Web-log) server, a bulletin board server or a review site server. The comments disclosed by the comment server 2 are, for example, tweets released on the Twitter (registered trademark) sites.
As one embodiment, another page disclosing server 3 may be connected to the Internet under the configuration where a proxy server 1 is disposed at the position of the page/site server. The proxy server 1 serves as a proxy for mediating between the terminal 4 and the page disclosing server 3 and sends to the terminal 4 a page content delivered from the page disclosing server 3. To the page content, the proxy server 1 attaches a scroll control code used for immediately displaying the noteworthy place.
The terminal 4 may be, for example, a smartphone, a cellular phone, a personal computer or the like, which allows a user to browse page contents through a browser. The terminal 4 accesses the page/site server 1 thereby to display a part or (if possible) the whole of the obtained page content with the browser. According to the present invention, the noteworthy place which interests every user in the page content is displayed with the page content scrolled.
The following explanation is premised that, as shown in
In the embodiment shown in
(Page-content storing unit 10) The page-content storing unit 10 is configured to store page contents in advance. The unit 10 may store (URLs (Uniform Resource Locators) of) new page contents gathered by using, e.g. RSS (Really Simple Syndication/Rich Site Summary).
According to
(Comment group retriever 11) Returning to
As shown in
Page content: “α Corporation Releases New Portable Terminal X!” http://www.a.com/X.html
Comment Group:
“It's amazing performance.”;
“A little high price.”;
“I may buy it, if it's in the 20 thousand-yen range.”;
“I don't buy it.”;
“Wastefully high performance www”;
“α Corporation has this type of value-range.”;
“A bit pricy, but good buy as high cost-effective.”;
“Amazing! α Corporation's new terminal has super high performance (*̂ô*)”;
“What is this? I Want!”;
“I want this. Low price! Maybe I should buy this tomorrow.”;
“Come on wwwwww”; and
“I wish it were a little cheaper.”
(Characteristic word extractor 12) Returning to
The characteristic word extractor 12 is adapted to use morpheme analysis to extract words from the text included in the comment group. The “morpheme analysis” is a technique that divides a sentence into words each having a certain meaning and uses dictionaries to determine the part-of-speech or the content of each of the words. The “morpheme” means a minimal unit that is a sentence component having a certain meaning. Words that are regarded as characteristic are extracted with TF-IDF method from the words extracted by using morpheme analysis. Here, the TF-IDF method is a technique which weights each extracted word to express a sentence including the words as a vector by using a query, and ranks the extracted words by the degree of similarity between the sentence and the query. The larger the rank value given to an extracted word is, with the higher possibility the extracted word is recognized as a characteristic word. For example, the appearance frequency of each of the words included in the title or body of each news article may be used as a TF, and the appearance frequency of each of the words included in all the news articles may be used as an IDF.
According to
In the just-described example, the characteristic word “performance”, which has the highest appearance frequency, is outputted to the characteristic word retriever 14. If a characteristic word with the highest appearance frequency is not included in the page content, outputted is a characteristic word with the second highest appearance frequency.
(Concept dictionary 13) Returning to
As an alternative, the characteristic word extractor 12 may be configured to extract a plurality of characteristic words then to convert these characteristic words into generalized words by using the concept dictionary 13 and thus to output the generalized word with a high appearance frequency as a characteristic word.
In the above-described example, a plurality of characteristic words are converted into the following generalized words.
Subsequently, there calculated as follows is the appearance frequency of each of the generalized words into which the characteristic words have been converted.
In the just-described example, there outputted to the characteristic word retriever 14 is the generalized word “value” which has the highest appearance frequency (as well as the characteristic words “price”, “thousand yen” and “cost-effective”).
(Characteristic word retriever 14) The characteristic word retriever 14 is configured to retrieve a place where the characteristic word appears in the page content.
Here, when retrieving the appearance place of, e.g. the characteristic word “performance”, the following page-content place is retrieved from the page content shown in
“Supreme ‘Performance’!”
Further, when retrieving the appearance place of, e.g. the characteristic word “value”, the following page-content place is retrieved from the same page content shown in
“The ‘price’ is 3,150 yen, including tax.”
(Browsing-part display controller 15) The browsing-part display controller 15 is configured to control the objective page content to be displayed in such a way that the user can browse the appearance place of the characteristic word included in the page content. Specifically, there attached to the page content is a scroll-control code which allows the noteworthy appearance-place to be displayed immediately.
Practically, either or both of the following two displaying methods may be adapted.
(Displaying method 1) A page part including the characteristic word of the page content is displayed at the top or center of the terminal display area (by direct jump to the top or center), and in the form of being scrolled if needed.
(Displaying method 2) The characteristic word of the page content is highlighted. For example, the characteristic word may be marked with a fluorescent color then to be displayed.
In the case that the characteristic word is “performance” included in the page content shown in
“Supreme ‘Performance’!
64-bit CPU included, OS version 5.1,
High resolution comparable to TV display, Camera with high-speed shutter,
What's more Charging cable for charging between smartphones!”
The HTML code of the place including the above-described characteristic word “performance” is as follows.
Thus, the sentence line “Supreme Performance!” is searched out and displayed by referring to the following URL, for example.
http://server/test.html*highlight
In the case that the characteristic word is “value” included in the page content shown in
(Page content retriever 16) Returning to
