DESCRIPTION

â € œDATA SEARCH SYSTEM â €

The present invention refers to a data search system in a search engine, with particular reference to search engines operating on unstructured data such as Google, Yahoo and Bing, for evaluating the availability of a good or service on the internet .

In addition or alternatively, the system provides the price corresponding to the ads generated according to the search string.

In addition or alternatively, in the event that there is a charge for each â € œclickâ € made on an advertisement (so-called â € œpay -per-clìcKâ € ™ system), the system according to the invention can be able to determine this amount dynamically.

Unstructured data means data that is not organized in schemes or does not use any predefined scheme. In particular, but not exclusively, the invention search system can search for data on the availability of books in a library or rooms in a hotel and the following description is provided with reference to these fields of application for the sole purpose of simplify its presentation.

TECHNIQUE NOTE

As is well known, search engines are programs located on websites that search for information on the internet through the use of keywords. A feature recently added to search engines contemplates the possibility of inserting a result in a privileged position on the search results web page.

This presentation mode is called a sponsored link. Currently the three major search engines: Google, Yahoo and Bing offer promotional tools that cross the searches made by their users with paid promotional ads, made by the suppliers of goods or services based on data matching criteria ("matching of data"). In fact, suppliers of goods or services define a series of keywords with which they want to be found in searches and insert them in a memory module made available by the search engine. The search engine therefore, based on the requests made by internet users, presents a list of links and announcements with the keywords entered by the suppliers of goods or services that correspond to the keywords of the request.

The manual insertion of the search keys in the search engine, however, is very penalizing if the variation of these keys is very frequent. This happens, for example, following a change in the availability and / or the type and / or price (if any) of a good or service.

In the case of books from a library, the availability varies frequently making it very difficult for a corresponding variation of the keywords that guarantee exact information on availability.

In the case of hotel room reservations, the hotel is forced to create countless different keywords to ensure the availability of ads in a search engine, for all periods of the year and for different lengths of stays. If we consider variable periods from 1 to 15 days in a single month, there are 450 different combinations (15x30 days) which multiplied by 12 months are 5,400 different combinations.

The sponsorship, on the basis of the originally chosen keywords, usually takes place with the â € œPay per Clickâ € system which includes some variants:

- Payment by volume of exposure or impression; in this case, the company contracts an amount for thousands of link views (CPM).

"Click" payment (CPC); in this case, the company only pays if the user clicks on the link.

Payment per Share (CPA); in this case, the company pays only if the user concludes a procedure on the site (eg booking or purchase of a good or service).

Unfortunately, however, this system still has a serious drawback; the data of the goods or services are continuously updated and the contents continuously modified.

The availability of a product or service, therefore, could be guaranteed by the relevant keyword in the search engine, but not really available from the supplier.

This could happen for a book in a library that is loaned to a new user or is sent for binding or pulping; in the case of a service, on the other hand, this could happen, for example due to the availability of a hotel room, simply for an unexpected reservation; the availability of rooms, in fact, can vary very frequently, resulting in a serious inadequacy of the information displayed in the sponsored links. In general, the higher the update / modification frequency of a website, the lower the reliability of the related keywords in the search engine.

The inadequacy of the information published affects both the supplier of goods and services investing in the sponsored link and the end user of the advertised good or service.

The supplier of goods and services is damaged, in fact, both if he sells goods or services (for example a hotel that rents rooms) and if he is not in any way interested in selling (eg library).

The internet user, on the other hand, is directed towards a result that does not provide the requested good or service, generating a longer and more expensive search than expected.

The manual insertion of the keywords, also in this case, is absolutely inefficient causing a worrying inadequacy of the information reported in the search engine.

The main purpose of the present invention is to provide a search system that guarantees an effective search for a good or service, with reliable and updated results both for the user of the search engine and for the supplier of goods or services sponsoring the your goods or services on the search engine.

SUMMARY OF THE INVENTION

These and other purposes are achieved by the data search system according to what is described in the attached claims.

The system according to the invention achieves the following advantages:

- consistency of the information provided by the supplier with the keywords entered in the search engine for its promotion;

- presence in the search engine of advertisements that contain more complete information than the simple list of goods / services supplied by the supplier;

the presence, among the information included in the announcements, also of information relating to the costs of goods / services;

automatic creation of the necessary key vvords combinations; - reduction of search times for the user of the search engine; - search optimization based on the search string;

- for the owner, reduction of the costs of maintaining the keywords of their goods or services promoted on the search engine.

These and other advantages of the invention will become clearer in more detail from the description, given below, of an embodiment thereof given by way of non-limiting example with reference to the attached drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 1. schematically shows the search system according to the invention.

DETAILED DESCRIPTION

Figure 1 shows a search system for data representative of goods or services as a function of a search string. The system comprises a computerized station 1, generally located in the home of a user of the system; from this station, the user interfaces in a known way to the internet network 100 which includes a plurality of web sites connected by an architecture of networks and subnets.

The system of the invention further comprises a search engine 5 on the internet network 100 adapted to receive a search string from a user,

For this purpose, a search interface 10 is provided in the search engines 5 to receive the aforementioned search string, preferably entered by the user of the computerized station 1.

The search engine 5, starting from this string, searches for ads representative of the data of goods or services offered on the internet.

All those search engines that operate on â € œunstructuredâ € data such as Google, Yahoo and Bing can be used as search engines for the system according to the invention.

By definition, data is unstructured when it is not organized in schemas or does not use any predefined schema.

In other words, the user of the search engine can enter, at will, search data not bound by any rule or constraint.

Obviously, the search engine 5 can be reached by an infinity of users located in an infinity of computerized stations connected in a known way to the internet through so-called â € œgatewayâ € access points,

The system of the invention further includes computerized stations 3 of third parties who intend to offer their goods or services on the Internet. The supply of goods or services includes both the simple publication of goods such as, for example, books from a library, photos from a photo album, etc., which are made available for consultation, and the sale of goods or services such as, for example, objects of different nature or the availability of hotel rooms to rent.

All data representative of the goods or services offered by the suppliers of goods and services are included in at least one memory module 2 of the computerized station 3.

Preferably, such a memory module 2 is included in one or more computerized stations 3.

In other words, the supplier of the goods or services to be offered has a local computerized station 3 where the data relating to the products (books or other) or services (availability of hotel rooms or other) to be offered on the internet reside. .

These suppliers offer their goods or services on the internet through booking engines indicated with 20 in the figure.

A booking engine is, in its broadest sense, an on-line booking program that allows you to maximize direct bookings of goods or services by checking availability and costs; in particular, in the case of reservation of paid goods or services, it allows to cancel the costs of intermediaries by maximizing direct bookings.

The booking engines are in data connection with the computerized stations 3 and able to collect in a first memory module 4 the information arriving from one or more of the aforementioned computerized stations 3.

Advantageously, according to the invention, the system comprises a first operating module 6; preferably, this first operating module 6 is a search engine channel manager (Search Engine Channel Manager (SECM)) which deals with the management of the offer of goods and / or services from the booking engines.

In other words, the SECM (first operating module 6) has access to the second memory modules 4 of one or more booking engines 20 which include at least part of the data representative of the suppliers' goods and / or services.

The supplier of goods or services may decide to have part or all of the data representative of his goods or services managed by the booking engine 20.

According to the invention, the operating module 6 will be able to advantageously process such data and then transmit them to one or more search engines 5. In other words, the first operating module 6 (channel manager of a SECM search engine) will be suitable to process all the information arriving from the second memory modules 4 (booking engine) and then transmit them to one or more search engines 5.

Preferably a specific application of the search engine, with its own database, will take care of receiving such data. The specific application is responsible for the search engine resources for web marketing.

At Google, for example, data is received via an application programming interface (API), such as the Google AdWords API.

Preferably a dedicated server hosts the first operating module 6; this server is located remotely both with respect to one or more second memory modules 4 and with respect to the search engine 5.

In other words, this server is located remotely, both with respect to one or more booking engine 20 and / or with respect to the computerized workstations 3, and with respect to the search engine 5.

Alternatively, this dedicated server can also host the same booking engine 20.

Alternatively, more booking engines can be located on different servers in connection with the first operating module 6.

As a further last alternative, the first operational module 6 can be included in the search engine 5.

The first operational module 6 is suitable for:

a) receiving all data representative of goods or services of at least a first memory module 4 of at least one booking engine 20;

b) automatically generate keywords related to the data of goods / services offered in the first memory module (4)

c) transmitting the generated keywords to a second memory module 41.

Preferably, the second memory module 41 is included in the search engine 5.

d) calculating all the possible combinations of the keywords on the basis of the data present taken from the first memory module 4;

e) generating all possible combinations of announcements associated with the keywords transmitted to the second memory module 41;

f) transmitting these generated advertisements to a third memory module 14, from which the advertisements to be shown on the search engine results pages are extracted.

Preferably, the third memory module 14 is included in the search engine 5.

g) receiving notification from the booking engines 20 of changes in the data contained in the first memory module 4;

h) updating the keywords in the second memory module 41 and the announcements in the third memory module 14, according to these variations.

From here on, the term â € œ announcementâ € will mean a series of data describing a good and / or service associated with keywords and, possibly, including keywords and / or an internet link (URL),

The continuous integration of the data coming from the booking engines 20 makes the advertisements more specific allowing the presentation of a series of results which are subsets of the starting result, and from which it is possible to choose the advertisement that best matches the desired search.

The ads shown in the search engine may contain the keywords entered in the 4 second memory modules of the 20 booking engines.

Preferably, the second memory module 41 is included in at least one search engine 5.

Preferably, the third memory module 14 is also included in at least one search engine 5.

Advantageously, according to the invention, the first operating module 6, which receives all the data representative of goods or services of at least a first memory module 4 of at least one booking engine 20, is able to generate all the announcements and / o keywords corresponding in a very short time to communicate them to search engines 5; this possibility was unimaginable with a manual insertion of the announcements as it happened in the known art.

Advantageously, according to the invention, the first operating module 6 is able to calculate all the possible combinations of the entered keywords in order to generate an ad for each combination.

The first operating module 6 constantly monitors the booking engines 20 in order to receive notifications of changes in the data contained in the second memory modules 4.

Variations may simply be changes in the availability of goods or services or changes in the characteristics of goods or services; these variations may correspond to changes in the keywords to be transmitted to the search engine, for example the cancellation / deactivation of a search field; these variations may also correspond to changes to the advertisements, for example, a new feature of a search field; these variations may further correspond to deletions / deactivations of search keys or advertisements,

The first operating module 6, having obtained this information, transmits it to the search engine 5 so that the advertisements in the third memory module 14 and / or the keywords in the second memory module 41 are updated, if necessary.

The communication of information to the search engine 5 is preferably carried out through a third operating module 17.

This module 17, through an application programming interface (API), is able to update the keywords in the second memory module 41 in the search engine 5 and the announcements in the third memory module 14, on the basis of the variations data representative of the goods (books) or services (renting rooms) provided.

Preferably, the third operating module 17 is included in the first operating module 6.

In general, it should be noted that in the present context and in the subsequent claims, the units described, namely the computerized station 3, the booking engine 20, the search engine 5 and the search engine channel manager 6, have been presented as divided into separate memory modules and operating modules for the sole purpose of clearly and completely describing the functionality of the units described.

In reality, some modules can be included in a single electronic device, suitably programmed to perform the functions described above, and can correspond to hardware entities and / or software routines of the programmed device.

On the other hand, they can be distributed on different computers locally or remotely based on the architecture of the network in which they reside.

The devices involved can also use one or more processors to execute the corresponding instructions.

Two embodiments of the present invention will now be described in greater detail,

In a first preferred embodiment, all the data of a library reside in the computerized station 3 and the advertisements generated on the search engine indicate the availability of books for consultation only and not for sale.

The first operating module 6, which receives from the first memory module 4 of at least one booking engine 20 the data on the books available in the library complete with title, author, publisher, any bibliographic references, reference indexes, dates relating to the beginning and fme loan etc., can generate all the ads and / or the corresponding keywords in a very short time and communicate them to search engines 5 to put them into action; these announcements and the corresponding keywords will be stored respectively in the fourth memory modules 14 and in the third memory modules 41, preferably included in the search engine 5.

Advantageously, according to the invention, the operating module 6, based on the first memory module 4 of the booking engine 20 which has collected the information arriving from one or more computerized stations 3, generates the ads and / or keywords only for books for which the library has availability at the time of request, thus optimizing both the libraryâ € ™ s promotional investment in the Internet and any search engine user search.

At each change in availability (extension of a loan, return of a book from loan, start of a loan, etc.) or at each arrival of a new volume or, in general, at each variation of a characteristic reported in the first memory module 4 , the first operating module 6 updates all the ads on the search engines 5, activating new ones if books have become available or new books are available, and eliminating / deactivating ads and / or keywords for the books that have become unavailable or destroyed.

In a second preferred embodiment, in the computerized station 3 reside all the data of a hotel that provides rooms to rent on the internet. The first operating module 6, which receives from the first memory module 4 of at least one booking engine 20 data on the entire hotel room floor with all availability and prices, generates all the corresponding ads and / or keywords very quickly and communicates them to search engines 5 to put them into action; these announcements and the corresponding keywords will be stored respectively in the fourth memory modules 14 and in the third memory modules 41 included in the search engine 5.

Advantageously, according to the invention, the first operating module 6 is able to calculate all the possible combinations of the keywords entered in order to generate an ad for each combination.

In other words, if the user enters the words â € œhotel Rimini 2 - 7 Septemberâ € as a search string, the operating module 6 also calculates all the possible time combinations of stay from 2 to 7 September, that is to say from 2 to 3, from 2 to 4, from 2 to 5, from 2 to 6, from 2 to 7 and from 3 to 4, from 3 to 5, from 3 to 6 etc. A further example is shown below in which the first operating module 6 receives data from the first memory module 4 relating to date, number of available rooms and corresponding price:

Date Nr. Rooms Price

01 Aug. 3 € 100.00

02 Aug. 3 € 100.00

03 Aug. 2 € 100.00

04 Aug. 0 € 150.00

05 Aug. 2 € 150.00

06 Aug. 3 € 150.00

07 Aug. 3 € 150.00

Having received this data, the first operating module 6 generates all the combinations of announcements for the memory module 14 based on all the possible combinations of the availabilities present in the memory module 4; the announcements are listed here:

Advantageously, according to the invention, the first operating module 6, based on the first memory module 4 of the booking engine 20 which has collected the information arriving from one or more computerized stations 3, generates the announcements only for the dates in which the hotel has availability, optimizing in this way both the promotional investment in the internet of the hotel and the possible search of the user of the search engine.

Advantageously, the announcement will also contain information on the costs calculated by the first operating module 6, using the data made available by the booking engine 20.

As mentioned above, in the event that there is a charge for each â € œclickâ € made on an advertisement (so-called â € œpay-per-clickâ € system), the system according to the invention may be able to determine this amount dynamically.

Preferably, the following formula can be used:

CPC = auction base (service cost amount x C)

in which:

CPC = cost per click

auction basis = static amount determined by the seller of the good or service service cost amount = price calculated by the SECM, i.e. from the first operating module 6

C = multiplier coefficient set by the service vendor

By way of example, the following numerical values can be considered: auction base = € 0.50

service cost amount = € 300.00

C = 0.001

CPC = € 0.50 (€ 300.00 x 0.001) = € 0.80

Alternatively the system can process CPA (cost per action) or CPM (cost per thousands of impressions) instead of CPC (cost per click)

At each variation of availability or price, and in general at each variation of a characteristic reported in the first memory module 4, the first operating module 6 updates all the advertisements on the search engines 5, activating new ones if the rooms, by varying the amounts of the announcements if there have been price changes and by eliminating / deactivating announcements and / or keywords for the dates that are no longer available.

The user can use different formats for entering dates. The first operating module 6 in fact produces a series of keywords linked to the advertisement which also satisfy any different combinations.

In both embodiments, advantageously according to the invention, the first operating module 6 allows to reduce to a minimum the possibility of advertisements on the search engine that do not have a concrete response in the goods / services supplied; this translates into a careful management of the supplierâ € ™ s advertising investment on the Internet.

In both embodiments, the second memory module 41 and the third memory module 14 can optionally be arranged outside the search engine 5 while maintaining the functionality and interactions with the search engine 5 and the booking engine 20 connected to the computerized station 3.

The first operating module 6 is generally responsible for the interfacing between one or more booking engines 20 and one or more search engines 5.

A second operating module 7, more specific, is able to generate non-standard advertisements on the basis of different operational strategies and particular search strings.

If the search string entered in the search engine 5 is expected to be incomplete, this second operating module 7 deals with the generation of advertisements on a statistical basis, presenting additional information which, statistically, has a good chance of being considered interesting by the user of the system, in relation to the incomplete search started.

Preferably, the second operating module 7 is included in the first operating module 6.

With reference to the second embodiment of the invention, for example, if it is envisaged that the search string entered in the search interface 10 of the search engine 5 lacks information relating to the dates searched, the advertisements displayed will report amounts and the dates set by the second operating module 7 obtained with the following modality. Preferably, the price of the stay is determined by the average number of days of presence for the indicated month multiplied by the service rate.

Preferably, the dates of the current day are used as a basis, while the announcements of the length of stay are varied daily by adding a statistical date relating to the average days of difference between the booking date and the actual arrival date of the customer.

If it is expected that the search indicates only the day of arrival, you can optionally choose whether to submit an announcement with the price per day for the room (if for example the minimum stay is one day) or for an average period of stay.

Still with reference to the second embodiment, the creation of the announcements in the second memory module 41 could be determined by the second operating module 7 preferably by automatic generation of the announcements starting from the average number of days that elapse between the reservation date and the ™ actual arrival of the tourist.

In this way, the number of operations of the second operating module 7 would be much smaller and could be advantageous if the search engine placed limits on the number of active ads.

A variant of the system of the invention provides that, if the keywords entered by the user in the search engine are generic, the first operating module 6 generates a series of possible advertisements from which the supplier of goods or services chooses the most suitable for your business.

In the case of the bookshop, for example, announcements of all the books by the same author available can be generated, among which the manager decides which ones to publish as a result of the search.

In the case of hotel room reservations, the first operating module 6 checks the progress of recent bookings and therefore proposes corresponding solutions that satisfy the constraints set by the hotels and the availability present.

Advantageously, the first operating module 6 also provides for an optimization of the number of calls made to the search engine to optimize the resources used (transmission bandwidth and CPU cycles).

The optimization also includes the grouping of similar ads to be published on the search engine and the creation of pages in HTML code containing these ads.

At the end of each possible processing of the information coming in the first instance from the first memory module 4, and carried out by the first operating module 6, the search interface 10 displays the results.

Preferably, the results are returned to the user of the computerized station 1.

Preferably, the search results are displayed in the form of ads. Advantageously, according to the invention, a fourth operating module 8 receives the search string from the search interface 10, compares it with the keywords included in the second memory module 41 and produces the search results, in the form of the aforementioned announcements, by making a selection of the announcements included in the third memory module 14.

In other words, the fourth operational module 8 is able to receive the search string, to compare it with the keywords and to make a selection of the ads on the basis of this comparison.

The search string can contain search data of different nature, as already specified; these data can also include intervals or absolute cost values associated with information on the availability of a good or service.

Preferably, the fourth operating module 8 is included in the search engine
