DETAILED DESCRIPTION OF THE EMBODIMENTS
Before explaining the invention in detail, it is to be understood that the present embodiments are not limited to the particular embodiments disclosed and the invention can be practiced or carried out in various ways.
The embodiments of the invention include a system, a computer readable medium, and a method for quickly searching for a relevant phone number contained by searching relevant phone number information.
The invention is very user friendly and suitable for natural language searches. The embodiments can be integrated into a current search engine or can be a stand alone system for adding a click-to-dial feature to a search engine to establish a phone communication between a first communication device and a second communication device.
The embodiments of this invention can benefit businesses by quickly connecting customers to the correct person in a business with a fast search and one click connection. For example, it makes it easy for a first user of a cell service to contact another user of the same cell service For example, if a company advertises a new product, customers often will search for the new product on the World Wide Web. If the customer wants to talk to some one about the product or order the product, the customer has had to search the business' website for the correct phone number. The embodiments instead, allow the customer to click on a click-to-dial icon linking a number in a document to the correct person at the business to handle the inquiry.
The embodiments differ from current search engines in that the automated software is trained to automatically locate language information or other portions of documents with relevant phone information, then extract the relevant phone numbers from the relevant phone information and establish a click-to-dial icon which enables a user to activate the communication link and make a call.
An embodiment of the invention can be a computer readable medium for accepting a query and retrieving links to document, searching for relevant phone number information using the query, creating a click-to-dial icon to link a first communication device to a relevant phone number included in relevant phone number information identified by the query, and reformulating the query when no match occurs during the search for the relevant telephone number. The computer readable medium can further comprise instructions for establishing the at least one communication connection from the first communication device to a second communication device.
An alternative embodiment of the invention can be for a system that establishes a communications connection using voice recognition software, handwriting recognition software, typed characters, mouse clicks or combinations thereof as an input to the system.
The system can comprise a first communication device, a second communication device, search means which are instructions on a computer readable media, hereafter termed “search software”, access means which are instructions on a computer readable media, which are hereafter termed “search software” and click-to-dial means, which are instructions on a computer readable media, and are hereafter termed “click to dial software”.
It should be noted that two U.S. Pat. No. 6,870,828 and U.S. Pat. No. 6,404,877 which describe portions of the access software included herein are hereby incorporated by reference.
The first communication device can be used for forming at least one communication connection between the first communication device and the second communication device. The first communication device, the second communication device, or both the first communication device and the second communication device can be a computer, a personal digital assistant, a voice of internet protocol phone, a public switch telephone network phone, a cell phone, or combinations thereof. A computer such as an HP® Compaq® NC6000, a Nokia® wireless phone, a Blackberry®, a Palm PilotTM, or similar device.
The search software can be adapted to accept a query such as “AT&T phone problem”. The search software can be a standard search engine such as Google®, a question and answering system such as AskJeeves®, an intelligent dialog system, or combinations thereof. The input to the search software can be in the form of text such as, keyword, or can be a spoken phrase, code input, natural language input, or combinations thereof.
The access software can be adapted to search for relevant phone numbers using the query to identify relevant phone information first. For example if the query was “AT&T phone problem” the click-to-dial icon can be connected to technical support, but if the query was “AT&T phone” the click-to-dial icon can be connection to the AT&T sales department. The access software can create at least one icon to link the first communication device to the relevant phone number identified by the query.
The search software can display links to documents, activating one of the links retrieves the document and then displays the document.
The click-to-dial icon can be a phone symbol, underlined text, bold text, different font from surrounding text, highlighted text, different color from surrounding text or combinations thereof. When implementing the embodiments, a single click-to-dial icon can be used for each document or multiple click-to-dial icons can be used for a single document, for example a document can have a phone symbol for one number and underlined phone number as the second number.
Often a search software retrieves two of the same document, when this occurs the access software uses the same click-to-dial icon for each document returned by the search software to limit the presentation to the user of multiples of the same phone number.
Next, the access software can perform a scan of documents retrieved by the search software.
The access software scans the retrieved documents identified by the search software for phone numbers listed in those documents and keywords identifying those phone numbers which were used in the query.
If phone numbers with keywords that match the words of the query are still not found, the access software reformulates the query using semantic (search for words with the same meaning) or syntactic (search for words with the same meaning) for relevant telephone numbers on the documents identified by the search software.
For example, if the query was for “AT&T phone problem”, the search software would find documents that are related to the query. The access software can search cached data for phone number information or scan the documents for identifiers relative to the query. Continuing with this example, the access software can create a click-to-dial link to connect the first communication device to a second communication device at AT&T technical support and not an AT&T sales or a general AT&T number.
In scanning the documents, the access software can recognize phone numbers, can distinguish a region surrounding relevant phone numbers, and can search the region for identifiers relevant to the input query. Alternatively, the access software can recognize identifiers relevant to the input query, can distinguish a region surrounding the identifiers, and can search the region for phone numbers. The region can comprise phone number information which comprises phone numbers and identifiers. The identifiers can be industry standard code, toll free number, area code, numbers, words, properties that identify the phone number, title of the webpage, symbols, section heading, paragraph title or combinations thereof.
The access software can rank the phone numbers from relevant phone number information according the identity and the proximity between the query and the identifiers within the region. The identity can be the semantic or syntactic difference between the identifiers and the query, and the term proximity refers to the number of words away from a phone number, the coordinate distance of the phone number, or combinations thereof. The coordinate distance is based on a measurement between the phone number and the identifiers, the coordinate distance can be measured in inches, meters, pixels, or other distance measurement. Proximity can be established by ranking a phone number by a scoring system. For example, a proximity 5 could mean the identifiers are next to the phone numbers; a proximity 3 could mean the identifiers are in the same line as the phone number and; a proximity 1 could mean the identifiers are on the same document as the phone numbers.
A phone number with the highest proximity ranking can be extracted and associated with the click-to-dial icon. When the scoring is completed and no phone numbers with scores above a preset threshold are found, the access software is designed to prevent a click-to-dial icon from being generated. In other words, when the system is not confident the phone number with the highest proximity score is the correct relevant phone number to provide to a user, a click-to-dial icon is not generated.
Relevant phone number information can comprise a relevant phone number and an identifier. The identifier can be an standard industry code, a toll free number, an area code, numbers, words, properties that identify the phone number, a title of a webpage, symbols, a section heading, a paragraph title or combinations thereof.
Relevant phone information can be cached as “cached data.” Cached data can be updated with information provided by the customer or updated by scanning the identified documents. A date on the cached data to identify the last update to the document. The cached data can comprise a phone number, an identifier, a previous query, the date the cached data was stored, or combinations thereof.
A document owner can supply data to be cached, such as the relevant phone numbers, to the access software. The document owner might supply a list of phone numbers to the owner of the access software. These phone numbers can be the numbers to the sales department, technical support, marketing department or some other department within the company. A document owner can additionally supply identifiers to associate with the phone numbers. For example the document owner might want the words “problem”, “does not work”, or “broken” to be associated with the technical support number, the words “advertising” to be associated with the phone number of the marking department, and all other queries to be transferred to the sales department. Alternatively, the document can be searched for identifiers to associate with the phone numbers supplied. The documents can be web pages, advertisements, other multimedia documents or combinations thereof.
The click-to-dial software can establish at least one communication connection from the first communication device to the second communication device. When the second communication device is used in a call center at a business, the second communication device can accommodate multiple origination devices. The first communication device can accommodate communication connections to multiple second communication devices. The communication connection can be through voice over internet protocol, public switch telephone network, or combinations thereof.
The provider of the access software can use this technology to generate payments. The payments can be received by the access software provider (for example, the owner of the search page) from the document provider (for example, the owner of a web site) when a communication connection is established to the document provider and the document provider is also the owner of the phone number.
In an alternative embodiment, payment can be received by the access software provider (for example, the owner of the search page) from a user conducting a search (for example, a customer) when a communication connection is established to the document provider and the document provider has not agreed to pay for a click-to-dial link to be associated with their documents.
The document provider will only have a click-to-dial link on their document if the document provider agrees to pay a royalty. Since some businesses do not want to receive calls if you are calling about something other than a sales call, the businesses can restrict the click-to-dial icon to only connect to the sales department. The document provider can provide phone numbers and even keywords related to the phone numbers; however, a search can still be done to extract additional keywords. If the document owner does not provide the phone numbers, the access software will extract the phone numbers.
Another embodiment of the invention is for a method of creating a communication connection from a first communication device to a second communication device that is quicker and easier to use with less actions to speak with a business than currently exist. The method can comprise the steps of accepting a query by search means, and retrieving links to a document using the search means.
The method can comprise the step of searching for relevant phone number information on documents using an access means, ranking the relevant phone number information identified, and identifying a relevant phone number in the relevant phone number information. The step of searching for relevant phone number information can comprise retrieving cached data. If the query and the cached data are not similar, the method can include the step of retrieving phone numbers connected to the identified links using access software.
The step of searching for the relevant phone number information can be by scanning the documents identified by the links for the relevant phone number.
An additional step of the method can be associating the relevant phone number with at least one click-to-dial icon from the scanned page. If the click-to-dial icon is activated, a connection between a first communication device and a second communication device is established.
Activating the click-to-dial icon can be by a mouse click, a keyboard stroke, or some other way of relaying the proper choice to the click-to-dial software. If the connection is lost, the click-to-dial icon can be reactivated in order to reestablish the communication connection between a origination device and a second communication device.
The method can comprise the additional step of filtering the retrieved relevant phone numbers retrieved based on a user's special request, a region, a last updating of a document, type of document, language, combinations thereof. The type of document can be a word document, an xml document, a portable document file or any other type of document used on the World Wide Web, or combinations thereof.
The method can additionally comprise the step of updating cached data if cashed data is used, when the date of a retrieved document is newer than the date the data was stored as cached data. The access software can limit the search of documents for phone numbers to specified levels. For example, a single page [A] might link to two pages [B] and [C] and page [B] might link to page [D] and [E]. Page [A] would be considered level 1; page [B] and page [C] might be considered level 2; and page [D] and page [E] might be considered level 3. The access software can limit a scan of retrieved documents to a specified number of levels, such that level 1 or levels 1 and 2 are searched. The use of levels to filter a search can reduce the time needed to scan every level before deciding what number to associate with the click-to-dial icon.
The method can comprise the step of receiving payment by the access software provider from an owner of a phone number when the click-to-dial icon is activated.
With reference to the figures, FIG. 1 depicts a diagram of an embodiment of the invention. A first communication device (10) can be used for forming at least one communication connection (12) between the first communication device (10) and a second communication device (14). A search software (16) can be adapted to accept a query (18).
An access software (20) can be adapted to search for relevant phone numbers (22) using the query. The access software can create at least one icon (24) to link the first communication device to a relevant phone number identified by the query.
A click-to-dial software (26) can be adapted to establish the at least one communication connection from the first communication device to the second communication device.
FIG. 2 depicts a flow chart of an embodiment of the method. The method for establishing a communication connection between a first communication device and a second communication device can comprise, accepting a query by search means [100], and retrieving links to a document using the search means [110].
The method can comprise the step of searching for relevant phone number information on documents using an access means [120] and ranking the relevant phone number information identified [130]. Another step can include identifying a relevant phone number in the relevant phone number information [140].
An additional step of the method can be associating the relevant phone number with at least one click-to-dial icon [150]. When the click-to-dial icon is activated [160] by a user, a connection between a first communication device and a second communication device can be established.
FIG. 3 depicts a representation of an embodiment of a click-to-dial icon useable herein. A query (18) for “AT&T” into a search field might return a document similar to that depicted in FIG. 3. When a search button (30) is activated, the links (32) are retrieved with their web address below. A click-to-dial icon (34) is shown below the web address. The access software created this click-to-dial icon (34) by searching for relevant phone numbers based on the query. The link (36) does not have a click-to-dial icon because either the query did not return any phone numbers that are relevant phone numbers, or if an owner does not agree to pay a royalty for participating in the click-to-dial search.
While these embodiments have been described with emphasis on the embodiments, it should be understood that within the scope of the appended claims, the embodiments might be practiced other than as specifically described herein.
