16. A non-transitory computer-readable storage medium on which is encoded executable program code, the program code comprising: program code for determining a collection of named entity terms within a data store coupled to a computer of a user, a named entity term having an associated weight indicating a likelihood that the named entity term is included in a named entity; program code for identifying an event comprising a user interaction with an article on the computer; program code for identifying a plurality of named entity terms associated with the event; program code for identifying, from the collection, the weight associated with each of the plurality of named entity terms; program code for automatically creating an implicit search query responsive to identifying the weight associated with each of the plurality of named entity terms, the implicit query based at least in part on the plurality of named entity terms and the associated weights, the implicit search query based on a first named entity term with an associated weight indicating a higher likelihood that the first named entity term is a named entity more than on a second named entity term with an associated weight indicating a lower likelihood that the second named entity term is a named entity; program code for generating, from the computer, a plurality of search results relevant to the implicit search query; and program code for providing for display the retrieved plurality of search results.
