26 . The method of claim 21 , wherein the first information comprises a link to a website, the website comprises a web page, and the third information is obtained from the web page.

27 . The method of claim 21 , further comprising:

ranking each of the plurality of persons using the updated profile data; and

synchronizing, using the ranking, data among different computing devices of a user, the different computing devices including the first computing device.

28 . A non-transitory machine readable storage medium embodying instructions, the instructions to cause a computing device to:

obtain profile data including a profile for each of a plurality of persons, the profile data related to persons used in messages to or from a user of the computing device;

extract first information from a first message of the messages;

perform, over a network, a first search using the first information as search criteria to obtain second information;

store the second information as part of the profile data;

perform a second search using the second information as search criteria to obtain third information; and

update the profile data using the third information.

29 . The non-transitory machine readable storage medium of claim 28 , wherein the second search is performed after the storing the second information.

30 . The non-transitory machine readable storage medium of claim 28 , wherein the profile data is stored on the computing device.

31 . The non-transitory machine readable storage medium of claim 28 , wherein the persons used in messages to or from the user comprise a person that is identified in a body of the first message.

32 . The non-transitory machine readable storage medium of claim 28 , wherein the first search is performed in response to the computing device receiving the first message.

33 . The non-transitory machine readable storage medium of claim 28 , wherein the first information comprises at least one of a link to a website, a social network name, an electronic address, or a telephone number.

34 . The non-transitory machine readable storage medium of 28 , wherein the second information comprises at least one of a photo, a phone number, or an electronic address.

35 . A system, comprising:

at least one processor; and

memory storing instructions configured to instruct the at least one processor to:

obtain profile data including a profile for each of a plurality of persons, the profile data related to persons used in messages to a user of a first computing device;

extract first information from a first message of the messages;

perform a first search using the first information as search criteria to obtain second information;

store the second information as part of the profile data;

perform a second search using the second information as search criteria to obtain third information; and

update the profile data using the third information.

36 . The system of claim 35 , wherein the instructions are further configured to instruct the at least one processor to:

rank each of the plurality of persons using the updated profile data; and

synchronize, using the ranking, data among different computing devices of the user, the different computing devices including the first computing device.

37 . The system of claim 35 , wherein the first information comprises a link to a first website, and the second information comprises a link to a second website.

38 . The system of claim 35 , wherein an electronic communication address of a sender of the first message comprises a domain, and the search criteria for the first search comprises the domain.

39 . The system of claim 35 , wherein the second information comprises a link to a website, the website comprises a web page, and the third information is obtained from the web page.

40 . The system of claim 35 , wherein the instructions are further configured to instruct the at least one processor to:

receive an incomplete input made by the user via a user interface; and

cause presentation of at least one address suggestion to the user for completion of the incomplete input, wherein the address suggestion is based on the updated profile data.
