Description

Telephone number replying system for providing multiple search service analyzing telephone number description}

The present invention constructs a DB consisting of a plurality of keywords and phone numbers by automatically analyzing the description registered by the phone number subscriber for the phone number guide application, and using the DB to guide the phone number retrieved in the multi-search process A system and telephone number guidance method.

 Telephone Number Subscribers apply for a telephone number guide service to provide their telephone number to others. In addition, the telephone number provider categorizes the subscriber's requested telephone number into a business type, business name, etc. and guides the user to inquire. In such a telephone number guide service, the subscriber hopes that more keywords are registered in his / her telephone number so that his / her telephone number is preferentially guided to the user's inquiry call.

Accordingly, the subscriber himself defines the keywords by himself and requests the operator to register the keywords, and the subscriber registers the keywords of the user in the DB. Here, the registered keywords of the subscriber are descriptive information (eg, sales contents, advertisements, unusual matters, etc.) describing the telephone number, and the relations between the keywords are not defined.

The telephone number search service provided by the telephone number service provider includes a mutual search service and an industry search service. The mutual search service enters the exact business name that a user inquires as a search keyword, and guides the business name telephone number to be searched as a search keyword from a DB. If the user does not know the exact business name, the operator searches for the user's inquiries, enters the appropriate industry keyword, guides the user to the search result, and then enters the next keyword according to the user's intention. It is to guide the retrieved phone number.

In the aforementioned industry search service, the search efficiency is determined according to the ability and work experience of the guide. In other words, since the experienced guide has encountered many user inquiries, he / she grasps the contents of the user's inquiry and selects and inputs appropriate keywords. However, as described above, since the data construction of the DB itself is registered without any relation between the keywords, the guide must select and enter a keyword directly only by his or her search ability.

If an association relationship is established between the search keywords, after the receptionist first inputs a search word, search words highly related to the input search word may be sequentially displayed on the screen of the guide terminal. This association indicates that there is a high statistical probability of being selected as the next search term input from the guide among the search terms presented as candidates for the previous search term. Therefore, when the guide selects the relevant search term suggested as a candidate and performs the next search, input of the search term will be much easier. Furthermore, even search efficiency will be obtained from all guides without depending on the search ability of individual guides.

The present invention was created in view of the above-described points, and automatically extracts and stores search keywords from subscriber's phone number description information, and constructs a search word DB that defines the relevance of the search keywords using individual phone number guides. For the purpose of

When the words and the morpheme-specific words are analyzed as shown in Table 2 above, the representative keyword selecting means 222 counts the number of appearances (the extraction frequency) of the individual words and selects the representative keywords (S222). The number of appearances of the individual words in Table 3 is illustrated below.

word Number of appearances [Jukkumi] 4 times [24 hours] 3rd time [Sashimi / wa] Episode 2 Sushi,
[Sushi Specialty] Episode 2 [parking] Episode 2 [Rotary Sushi / Silver], [Rotary Sushi] Episode 2

When the individual words are sorted by the number of appearances as shown in Table 3 above, keywords having more than the number of appearances are selected as the representative keywords. Keywords such as [Japanese Restaurant, Haejangguk], and Gwanghwamun, which have low appearances, are eliminated from the selection of representative keywords.

The similar keyword selecting means 223 checks whether the first syllable of the individual representative keywords is the same, and selects a long word including the representative keyword as the similar keyword and stores the representative keyword and the similar keyword in the similar keyword DB 201. (S223). For example, in Table 2, if 'sushi' and 'sushi full text' are extracted from the word / morpheme analysis, it is judged whether the word is the same as the first syllable syllable, and 'sushi' is a representative keyword, and 'sushi full text' is a similar keyword. Classify. Table 4 below illustrates the field structure and data of the similar keyword DB 201 including the representative keyword and the similar keyword according to Table 3.

Representative keywords Keyword variations Jujube Jujube Fresh fish sashimi Fresh fish sashimi sushi Sushi, Sushi Specialty parking parking Rolling Sushi Rolling Sushi 24 hours 24 hours

When the similar keyword DB 201 of Table 4 is constructed, data of a group of telephone numbers corresponding to the telephone number description information from which the representative keyword is extracted is assigned to the representative keyword. Table 5 below illustrates the field structure and data of the keyword search DB 202 including the telephone number group assigned to the representative keyword by Table 4.

And industry type classification means 224 assigns an industry type to the representative keyword (S224). The industry type is an upper concept of a representative keyword and includes a plurality of representative keywords at a lower level. The keyword search DB generating means 225 stores information of the industry type, at least one representative keyword belonging to the industry type, and at least one or more telephone numbers belonging to the representative keyword in the keyword search DB 202 (S225). Table 6 illustrates the field structure and data of the keyword search DB 202 which assigns an industry to the representative keywords of Table 5.

Industry classification Representative keywords Phone number group Industry A

FIG. 6 shows a process in which the telephone number guide server 2 corrects data of the pseudo keyword DB 201.

Similar keyword data of the similar keyword DB 201 of Table 4 is periodically corrected (added) during the guide process. The keyword correction means 226 collects the search failed words when the search failure fails (S226), and the keyword correction means 227 selects the representative keyword or the similar keyword by providing the administrator with the failed search term. It adds to the similar keyword DB 201 (S227). For example, when a user inquires a "Jukkumi" store and a receptionist requests a search for "Jukkumi" as a search term, the keyword search DB fails because there is no data in the similar keyword DB 201, and as a result, the keyword search DB At 202, the representative keyword search itself is not possible. At this time, the search failed "tsukkumi" is collected and stored separately. In addition, the administrator searches for a failed search word and adds it as a new keyword or similar keyword of an existing representative keyword. Therefore, "jukkumi" may be added to the similar keyword DB 201 as a similar keyword of the representative keyword "jukkumi". Similar keyword DB 201 can reduce the search failure rate through the data correction of the administrator in the telephone number guide service process.

On the other hand, if the search is successful, the guide frequency increasing means 228 increases and stores the number of inquiries of the representative keyword inquired by the search whenever the phone number is guided to the user (S228). The accumulated count is used to search and sort secondary candidate search terms.

When the data construction of the similar keyword DB 201 of Table 4 and the keyword search DB 202 of Table 6 is completed, the telephone directory guidance server 2 may provide a telephone number guidance service for the user's inquiry. have.

FIG. 7 shows a process in which the phone number guide server 2 guides a phone number by performing multiple searches. For convenience of explanation, it is assumed that the user does not directly access the homepage to search for a telephone number but rather to call a receptionist for a telephone number.

The user terminal 4 is connected to the telephone number guide server 2 via a wired or wireless network and is connected to the guide terminal 5 by a call. When the user inquires a sushi restaurant and the receptionist enters the search word "sushi" in the receptionist terminal 5, the search term receiving means 231 receives a telephone number search request including the search word (S231). .

The representative keyword inquiry means 232 extracts a search word and inquires the similar keyword DB 201 to inquire the representative keyword (S232). In the search result, a representative keyword of "sushi" is searched.

The multiple search result providing means 233 inquires the telephone number group information of the representative keyword searched for "sushi", and the search results are three telephones of "111-2222", "222-2222", and "333-3333". Search for the number. In addition, the second candidate search word is searched in the order of the high number of guides among the representative keywords of the searched three phone numbers, added to the search result, and transmitted to the guide terminal 5 (S233). The second candidate search word is a representative keyword that has been frequently searched for the phone numbers searched for by the search word "sushi" and can further narrow the search range, and thus is a search word highly likely to be continuously input by the guide. In addition, the second candidate search word corresponds to a search word highly related to the search word used in the search. Table 7 shows the search results received by the receptionist terminal 5 and displayed on the screen.

search word sushi 2nd candidate query [Phone number] [Mutual] [Address] [Industry]
111-1111
222-2222
333-3333 <Industry A>
Sashimi, Seafood
<Industry B>
Parking, 24 hours

 Therefore, the guide receives the search results as shown in Table 7, grasps the contents of the user's inquiry, and selects a search term that best matches the contents of the inquiry from the secondary candidate search terms to request the secondary search. When this process is repeated, the receptionist enters a search word only at the first search, and afterwards, a multi-search occurs in which the second candidate search word is presented and selected, and the user is finally provided with the searched phone number.
