Location-based search-result ranking for blog documents and the like
View Patent ↗In one embodiment, a mobile communication device is adapted to provide geography-enhanced blog search results. In response to a blog-search query entered by a user, the mobile communication device is adapted to determine a current geographical location for the mobile communication device and a home location for the user. The mobile communication device is further adapted to provide the current location and home location information along with the search query parameters to a search engine. The search engine is adapted to provide results corresponding to blog posts that satisfy the parameters of the search query, wherein the search results are ranked based on at least one of (a) the geographic proximity of a blog post subject to the current location and (b) the geographic proximity of a blog post author's home location to the user's home location.

(a) allow a user of the communication device to provide a search query having one or more search parameters;
(b) automatically acquire location information indicating at least one of (i) the current location of the communication device and (ii) a home location for the user of the communication device;
(c) transmit the search query and the location information via a communication network to a search engine, wherein the search engine is adapted to:
(1) search a collection of documents using the one or more search parameters to obtain two or more search results, wherein each of the two or more search results corresponds to a different document in the collection of documents;
(2) rank the search results based on the location information; and
(3) transmit at least some of the ranked search results to the communication device; and
(d) display the received ranked search results, wherein:
the location information indicates the current location of the communication device;
the search engine is further adapted to determine a current zone of interest based on the current location of the communication device;
the search results are also ranked based on the current zone of interest;
the current zone of interest has at least one of a shape and size based on the current location;
the communication device has a velocity indicating a speed and a direction of the communication device;
the location information further indicates the velocity of the communication device; and
at least one of the shape and size of the current zone of interest is based on the velocity of the communication device.
2. A computer-implemented method for providing search results ranked based on location, the method comprising:

receiving location information corresponding to the communication device, wherein the location information indicates at least one of (i) the current location of the communication device and (ii) a home location for the user of the communication device;
searching a computer-accessible collection of documents using the one or more search parameters to obtain two or more search results, wherein each of the two or more search results corresponds to a different document in the collection of documents;
ranking the search results based on the location information; and
transmitting at least some of the ranked search results to the communication device, wherein:
the location information indicates the current location of the communication device;
the search engine is further adapted to determine a current zone of interest based on the current location of the communication device;
the search results are also ranked based on the current zone of interest;
the current zone of interest has at least one of a shape and size based on the current location;
the communication device has a velocity indicating a speed and a direction of the communication device;
the location information further indicates the velocity of the communication device; and
the at least one of the shape and size of the current zone of interest is based on the velocity of the communication device.
3. A computer-implemented search engine for a communication network having a communication device with a current location, the search engine adapted to:
receive from the communication device a search query having one or more search parameters provided by a user of the communication device;
receive location information corresponding to the communication device, wherein the location information indicates at least one of (i) the current location of the communication device-and (ii) a home location for the user of the communication device;
search a computer-accessible collection of documents using the one or more search parameters to obtain two or more search results, wherein each of the two or more search results corresponds to a different document in the collection of documents;
rank the search results based on the location information; and
transmit at least some of the ranked search results to the communication device, wherein:
the location information indicates the current location of the communication device;
the search engine is further adapted to determine a current zone of interest based on the current location of the communication device;
the search results are also ranked based on the current zone of interest;
the current zone of interest has a shape and size based on the current location;
the communication device has a velocity indicating a speed and a direction of the communication device;
the location information further indicates the velocity of the communication device; and
at least one of the shape and size of the current zone of interest is based on the velocity of the communication device.

5. The invention of claim 3 , wherein the size of the current zone of interest is based on the velocity of the communication device.
6. The invention of claim 5 , wherein the search results are ranked based on both (i) the current location of the communication device and (ii) the home location for the user of the communication device.
7. The invention of claim 6 , wherein:
at least two documents corresponding to the two or more search results have associated content location information and document-author home location information; and
