Search device, search application, and search method

The present invention provides a function for a user to index a website that is not included in the results of a web search engine by himself/herself using a web crawler. There is a function that allows the user to log in to the present invention in one step with a login function. The present invention relates to a personal search engine with a login function and a web crawler.

Conventionally, in a case where searching for information on the web, general users have searched only the websites registered on the search site operated by the search engine operating company.

The general users could not decide which site to be indexed by themselves, and searched for the site registered by the algorithm or the standard of the search engine operating company. The users such as researchers who wanted more information found the lack of the search results.

Problems to be Solved by the Invention

More specifically, conventional search engines in general have the fundamental drawback that the users including the researchers cannot create a database of the information that the users want to search for. In addition, according to the survey as of 2014, even the search engine company with the largest market share in the world is said to cover only 4% of all sites on the Internet in its database. The traditional search engines have not been able to search for the information on other 96% of buried sites. Therefore, the search results are insufficient for users such as researchers. Further in addition, users using the common web search engines cannot use web crawlers to increase the search results of the search engine, even if the users try to increase the information on the website on a particular topic by themselves. In the present invention, the web is crawled according to the needs of the user. Therefore, the problem that the information is monopolized by some search engine operating sites or the problem that only biased sites are displayed is solved. The less biased sites that the users, including researchers, will want are indexed.

Means for Solving the Problems

The present invention builds a personal search engine on a page protected by a one-click SNS login function or an E-mail and password login function. Once the word which the user wants to increase is queried by an external search engine, the returned search result launches the web crawler. The web crawler can be started and stopped with a button on the web browser. Another way to increase the index data of the website may be to start the web crawler from the start URL.

The websites collected by the web crawler are added to the database with a single click. There is a way to search for websites collected from the same page as the web crawler. The present invention is the personal search engine and the web crawler with a login function having the above-described configuration.

The Effect of the Invention

The present invention makes it possible to acquire information that could not be acquired by the general web search engine. Researchers and users who need a wealth of information can freely increase and organize the information they are looking for.

According to our survey, general web search engines cover only 4% of all Internet sites. What this means is that, according to the present invention, even if an individual crawls, a rare or valuable site that is not listed in the web search engine can be found.

Hereinafter, an embodiment for carrying out the present invention will be described. The contents of the above-described [MEANS FOR SOLVING THE PROBLEMS] will be described in more detail.

The present invention has the following structure.

When using the present invention, the clicking the one-click SNS (social networking service) login function button on an mobile information terminal including a personal computer or a smartphone and equipped with a web browser is performed. In a case where the user does not have an SNS account, the login function is performed after registering with the registration function using e-mail and password.

After the login is completed, the URL will be redirected to the logged-in page.

On the page after login, the user enters the word (topic), that he/she wants to increase using the present invention, into the text box.

After the user's entering in the text box for word expansion and pressing the button, the word (topic) that the user wants to increase is automatically asked to the external search engine once.

The list of the search result URLs is returned from an external search engine. The list itself, and the websites indicated by the URLs on this list, are not displayed. The web crawler is activated by pressing the button for starting the crawl using the list of URLs of the search results. The web crawler extracts and collects the titles, the keywords, the descriptions, the summaries, and more of the web site. Web crawlers can also start crawling from the URL which the user wants to start.

The web crawler can be started and stopped from the web browser by pressing the button at any time. By pressing the Enter Database button, the website data collected by the web crawler is added. From the same page, the users can search for the websites collected by the web crawler. The data crawled using the password for the SNS login function or the login function using E-mail is protected, so the data will not be disclosed to third parties.

When adding crawled data to the database, harmful sites are filtered by a text filter using regular expressions, and then indexed into the database.
