Determining related keywords based on lifestream feeds

A system that is operative to manage a search query, comprising:

• an aggregator configured to crawl a plurality of network sites to retrieve updates to content at one or more of the plurality of network sites and provide a plurality of updates to life-stream feeds;
• and
• a keyword management component having computer-executable instructions, the computer-executable instructions when installed onto a computing device enable the computing device to perform actions, comprising:
• receiving a search query having at least one search term;
• examining the plurality of updates to life-stream feeds to identify a first subset of updates associated with at least one community of activities having at least one search term as a keyword;
• examining user profiles associated with the plurality of profiles to identify at a second subset of users for which the respective user profile include at least one search term as a keyword;
• searching each of the first and the second subsets of updates to life-stream feeds to identify other keywords co-occurring with the at least one search term;
• sorting the identified other keywords based on a frequency of occurrence of the other keywords;
• and
• providing at least some of the sorted keywords as related keywords to the at least one search term to a client device, such that at least one of the identified keywords is useable to modify the search query.

A computer-readable storage medium having computer-executable instructions, the computer-executable instructions when installed onto a computing device enable the computing device to perform actions, comprising:

• receiving a search query having at least one search term;
• examining a plurality of updates to life-stream feeds to identify a first subset of updates associated with at least one community of activities having at least one search term within associated content;
• examining user profiles associated with the plurality of profiles to identify at a second subset of users for which the respective user profile include at least one search term within associated content or user profile;
• searching each of the first and the second subsets of updates to life-stream feeds to identify keywords co-occurring with the at least one search term;
• sorting the identified keywords based on a frequency of occurrence of the other keywords;
• and
• providing at least some of the identified keywords as related keywords to the at least one search term to a client device, such that at least one of the identified keywords is useable to modify the search query.

A method that modifies a computing device such that the computing device is enabled to perform a search query, comprising:

• receiving a plurality of updates to content from life-stream feeds;
• receiving a search query having at least one search term;
• examining the plurality of updates to content from life-stream feeds to identify a first subset of updates having the at least one search term as a keyword;
• examining the plurality of users to content from profiles to identify at a second subset of users for which the respective user profile include at least one search term as a keyword;
• searching each of the first and the second subsets to identify other keywords co-occurring with the at least one search term;
• sorting the identified other keywords based on a frequency of occurrence in the subsets;
• and
• providing at least some of the sorted keywords as related keywords to the at least one search term to a client device, such that at least one of the identified keywords is useable to modify the search query.
