Examples of keywords used in embodiments of the invention are company names, trademarks, book titles, personal names, document titles or any natural language string capable of being printed and easily memorized by a person.
  • the second component comprises a server side navigation engine that indexes the individual words within a name as well as the first letters of a destination's keyword. These indexing features enable the navigation engine to return a list of results even when the query only contains the first few characters of the keyword.
  • the third component comprises an estimated measure of popularity for each destination within the database. An example of popularity measure supported by embodiments of the invention is the number of times a destination has been visited by all users within a given time range.
  • Embodiments of the invention support many suitable measures of popularity. Some embodiments include popularity measures for the navigation system in which the user can be identified and tracked over time. In such embodiments, the measure of popularity can be customized to the specific user.
  • One example of user-centric popularity metric is the number of times the user has visited the destination within a given time range.

  • the present invention includes an addressing system optimized for retrieving networked based resources via a handheld, wireless device.
  • Present addressing systems are inadequate for the new generation of handheld wireless devices.
  • Handheld devices such as cellphones and wireless PDAs have constraints on the length of input strings that a user may reasonably be expected to input. This limitation has not been an issue in PC-based network access, as PC based browsers typically accept a URL, which may be an arbitrarily long string. For instance, to access a URL such as "www. amazon. com", a PC user typically types in the entire string corresponding to the URL.
  • Figure 1 illustrates a WAP phone, which includes a display 100.
  • the input to the phone 102 is typically a standard numerical key pad, including roughly 12 keys, appended with a cursor key 104 to highlight lines on the display 100.

  • Query a set of parameters passed by the client 200 (e.g. handset) to the navigation server 202.
  • the query comprises a query string and a query context.
  • the query string may comprise any text or keystrokes input by a user of the client 200 device.
  • the query context is any direct or indirect contextual information about the user or the query. Non-limiting examples of query context include: the user's preferred language, the user's geographical location, a unique identifier corresponding to the user. If no context information is to be transmitted from the client 200 to the navigation server 202, the query context may be null.
  • Resource an entity (Web page, person, MP3 song,...) on the network that can be uniquely identified by a URI.
  • Entry a parameterized object that describes a resource. The object parameters are also called attributes or properties. Two important entry attributes in the present invention are the keyword and the URI.
  • Keyword fragment one or more letters of a keyword (e.g. ama for amazon).
  • Relevance ranking The relevance of an entry with respect to a query is a function of how closely the given entry matches the query string and context. For instance, if the query context specifies that the user only wants results in French, all the entries in English may be regarded as irrelevant even though their keyword may be similar to the query string. If there is no context, the relevance of an entry to a user query is a direct function of comparing the query string to the entry keyword.
  • Exact match An exact match occurs when all the query parameters (query string and context) are exactly matching the corresponding parameters of an entry. Two parameter values are exactly matching when their normalized values are equal.
  • the query context may provide a mechanism to identify a specific user (e.g. subscriber ID from wireless operator or login ID).
  • the global measure of popularity may be customized to the specific user.
  • the resources visited by the user and the frequency of these visits can be aggregated to build a usage profile specific to that user.

Abstract

L'invention concerne un système et un procédé permettant à des utilisateurs de naviguer jusqu'à un site de destination depuis un téléphone WAP ou un appareil réseau, en pressant uniquement quelques touches. Des modes de réalisation de l'invention comprennent une base de données de destinations Internet côté serveur, où la destination à l'intérieur de la base de données est signalée à l'utilisateur par mot-clé. Des exemples de mots-clés utilisés dans les modes de réalisation comprennent des raisons commerciales, des noms de marque, des titres de livres, des noms personnels, des titres de documents ou toute chaîne de données en langage naturel apte à être imprimés et à être mémorisés aisément par un individu. Des modes de réalisation de l'invention comprennent également un moteur de navigation côté serveur qui indexe les mots individuels dans un nom, de même que les premières lettres d'un mot-clé de destination. Les fonctionnalités d'indexation permettent au moteur de navigation de retourner une liste de résultats, même si la demande ne contient que les quelque premiers caractères du mot-clé. Des modes de réalisation de l'invention comprennent une mesure estimée de la popularité de chaque destination à l'intérieur de la base de données. Des exemples non restrictifs de telles mesures de popularité incluent le nombre de fois qu'une destination a été visitée par tous les utilisateurs sur une période donnée, et le nombre de références extérieures vers cette destination. Certains modes de réalisation comprennent des mesures de popularité adaptées à l'utilisateur spécifique. Un exemple de métrique de popularité orientée utilisateur est le nombre de fois qu'un utilisateur a visité la destination sur une période donnée. Le moteur de navigation peut retourner une liste de résultats classé par importance décroissante et par popularité décroissante.
