CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This non-provisional application claims priority to U.S. Provisional Patent Application Ser. No. 60/941,804, dated Jun. 4, 2007, the entirety of which is incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    Aspects of the invention relate to an automated method for searching advertisements. More specifically, aspects of the invention relate to searching classified advertisements using SMS text message commands and search criteria through a mobile device and existing mobile carrier networks. 
       BACKGROUND INFORMATION 
       [0003]    Classified advertisements are an important tool for commercial and private interests that need to obtain or sell goods and services. Print media, for example, has long dominated classified advertising to the extent that the sale of classified advertising has become a key profit center for newspaper economics. 
         [0004]    The rise of the Internet and computer interconnectivity has provided new opportunities for selling goods and services in addition to the long dominated classified advertising of print media. The print media, in response to the rise of Internet advertising, have decided to increase their selling opportunities and offer both traditional print advertising, as well as digital publication of advertising. This strategy can offer advertisers two distribution channels and command more revenue per advertisement. 
         [0005]    Conventionally, some internet portals, however, offer free advertising models for advertisers. As a result, newspapers are looking to offer greater value to their classified customers in order to keep generating profits from the advertising. 
         [0006]    Internet connectivity has developed from a stationary connection capability to a mobile connection capability. The media has recognized that mobile systems have developed an access standard allowing a similar environment as the World Wide Web. The mobile web offers a portable digital channel and allows the media to capitalize on its digital content. Classified ads are one of the most prevalent ways to monetize the mobile opportunity. 
       SUMMARY 
       [0007]    In one aspect, a method of mobile communication advertising is presented. The method entails steps of entering one of a primary function keyword and a vanity keyword to a mobile communication device and entering a search term in a form of a message string into a data processing module. The method then entails the steps of creating a list of category aliases, creating a list of category names, comparing the list of category aliases to the message string for a length, a category alias and a category name, identifying matches between the category aliases and the message string, wherein matches are placed into a search category list and removing matched category phrases from the search message to leave advertising search words. The method then entails determining a search sub-module based upon the advertising search words, conducting a search using the sub-module, and sending a search result obtained from the sub-module to a mobile communication device. The method then entails the steps of receiving the search result from the sub-module to a mobile communication device and displaying the search result on the mobile communication device.

     DETAILED DESCRIPTION  
       [0021]    Referring to  FIG. 1 , an overview  100  of a contextual search method embodiment is illustrated. The overview  100  provides for user access  102  to a system for processing requests, such as, for example, one that processes internet search requests. The contextual search method may be used to provide information, such as data, to individuals who are connected to a mobile network. The data, for example, can be related to results obtained from searching a real estate database for houses that fit defined data requirements. The data may also be related to other types of advertising databases, such as, for selling automobiles. A SMS receiver program  104  is configured such that the user may access the program  104  to send and receive messages through a mobile device, such as a mobile phone or PDA, as non-limiting examples. The SMS receiver program  104  is configured to interface with a search program  106 , for example to send and receive information between the SMS receiver program  104  and the search program  106 . The search program  106 , in the illustrated embodiment, is located on a computer server and is addressable by the SMS receiver program  104 , through programming. The search program  106  allows for queries to be received and processed through search programming and techniques provided therein. The search program  106  interfaces with a classified advertisement database  108 . The search program  106  attempts to match the search inquiry provided by the user to information contained in the classified advertisement database  108 . The database  108  may be a single database, or multiple databases, as necessary. The database  108  may contain information from various sources, such as advertisements for cars or real estate, as non-limiting examples. The database  108  may be maintained and stored on a separate addressable computer server. Interconnection between the database  108  and the search program is optimized to provide results quickly to a user providing an inquiry. The search program  106  thereafter interfaces with a SMS output program  110  that accepts data from the search program  106  and the results, as derived from the classified advertisement database  108 . The SMS output program  110  provides data to the mobile communication device, in this embodiment, a mobile communication device with an output display  112 . A user may access  114  the output display  112  to retrieve the information, as necessary. The SMS output program  110  may interface with standard data transfer capabilities. 
         [0022]    Referring to  FIG. 2 , a logical message flow diagram  200  of the contextual search embodiment is illustrated. A mobile handset keypad  202  for a mobile communication device is provided with a capability to interface with a mobile carrier network  204 . The mobile carrier network  204  may be any such common mobile carrier network, as conventionally known. The mobile carrier network  204  is connected to a SMS aggregation agent  206  that accepts and processes SMS messages emanating from the mobile carrier network  204 . The SMS Aggregation Agent  206  is connected to an input  208  of the computer server computer memory  212  such that information inputted into the computer server/computer memory  212  are evaluated. A storage unit  210  is configured to be addressed by the computer server/computer memory  212  such that contents of the storage unit  210  may be downloaded, as needed, for display. The computer server/computer memory  212  is connected to an output  214 . The output  214  may be a computer carrier network  204  to provide signals to a mobile communication device. Communications from the output  214  may be displayed  216  on the mobile communication device. 
         [0023]    Referring to  FIG. 3 , a logical search diagram  300  for the contextual search is illustrated. The diagram  300  provides for a SMS Text Command and Search String  302  to be entered to a mobile communication device, for example. The mobile communication device interfaces with a matching program  304 . The matching program  304  attempts to match the SMS Text Command and Search String  302  with defined categories provided in a database. The matching program  304  interfaces, in turn, with a results display  306  and a SMS result message with a dynamically generated URL link to result details  308 . The matching program  304  after matching the Text Command and Search string to the data obtained from, for example, an attached database, may download the information to an end user  310  that reads the results from a results display  306 . 
         [0024]    In an alterative path of the logical search diagram  300 , the matching program  304  produces a SMS Result message with a link to result details  308 . The end user  310  interfaces with the SMS Result message for retention of the information. 
         [0025]    Referring to  FIG. 4 , a method  400  of mobile communication advertising is presented. First, the method entails entering one of a primary function keyword and a vanity keyword to a mobile communication device  402 . Next the user enters a search term in a form of a message string into a data processing module  404 . Next, a list of category aliases is created  406 . Next, a list of category names is created  408 . The list of category aliases is compared to the message string for a length, a category alias and a category name  410 . Matches are identified between the category aliases and the message string, wherein matches are placed into a search category list  412 . Matched category phrases are removed from the search message to leave advertising search words  414 . A search sub-module is determined based upon the advertising search words  416 . A search is then conducted using the sub-module  418 . A search result obtained from the sub-module is then sent to a mobile communication device  420 . The search result from the sub-module is received to a mobile communication device  422 . The search result is then displayed on the mobile communication device  424 .

         [0077]    After the mobile user has constructed his text message, or before depending on the handset manufacturer, model and mobile carrier, a text message is sent to a common short code. The common short code is selected by the newspaper customer upon system installation. Upon receipt of the text search string, the search method of the mobile classified system is initiated.
       General Method   Primary function keyword or Vanity keyword determined (Search, view, etc.) and appropriate processing module initiated. In case of Vanity keywords, search is assumed and vanity keyword flags are set.   List of category aliases and category names is built.   Category list is compared to message string, in order of length (longest category alias/name to shortest) by category alias and then by category name. Matches are tracked by grandparent, parent, child tree (category, subcat, subcat, subcat) as per the order they appear in the message string. This means that if a category is matched, its children (subcategories) are searched for matching category names. Matches are determined and placed into search category list. This is the list of categories in which a matching advertisement must appear.   Matched category “phrases” removed from the search message to leave the advertising search words.   Based on the category tree as found in 3 above, the search sub modules is determined (Real Estate, Autos, Merchandise, etc.). Search sub-modules are specifically tailored methods, based on the general method to accommodate specific data requirements. For instance, automobile data contain make and model information which is not found in the Real Estate category. Each step in the following modules is used to narrow the possible result set for category-specific requirements.   Automobile Specific   Vanity keywords are compared to a search string. If a match is found, the search is limited to advertisement by the advertiser indicated by the vanity keyword.   All remaining words are matched against the database for make, model and year (if a numeric string), with the predetermined category/category tree (parent-child-child). Matching words eliminated from the search message.   Remaining un-matched words (not Vanity keyword, category, make, model, year) are matched against the advertisement body.   Real Estate Specific   the category tree structure of the Real Estate contains multiple entries of the same name, as the sub-structure indicates geographic areas. Thus, the same area may exist as a child of many parents. This information is taken into account during the search process and the search needs to allow for multiple points within the real-estate tree for any given search.   Vanity keywords are then compared to the search string. If a match is found, the search is limited to advertisements by the advertiser indicated by the vanity keyword.   Words are checked for a probability of being a zipcode. The information is matched against zipcodes that are available in the current advertisement set. If a match is made, the search is limited to those zipcodes.   The remaining words are compared to the Advertisement data.   Words are then compared to the area of information of advertisements, the property type of advertisements and zipcode of advertisements. Matching words are eliminated, and the result set is limited to matching advertisements.   The remaining search words are matched against the advertisement body (the description).   Merchandise   A. Non-category filter words are matched against the advertisement body.       
 
         [0097]    Search Results Processing 
         [0098]    Each search is assigned a unique incremental identification number and is associated with a unique result set that is stored in a table and assigned a unique URL. The Mobile Classified System constructs and sends a return SMS message that includes the total results in the search, static summary text, and the unique URL. As the mobile handset user navigates the URL, pages are generated and dynamically published to display the results according to a set of formatting rules.
