A computer-implemented system and method for updating user interest profiles is provided. An interest profile having a mapping of interest categories and interest scores for each interest category is obtained. User generated items are identified from online profiles and a portion of the user generated items are associated with a time stamp. A similarity mapping is performed by comparing each user generated item with each interest category. An interest index score is determined for each interest category based on one of the user generated items compared. A threshold is applied to the interest index scores for each category. The interest score associated with one such category in the mapping is replaced with the interest index score, when the interest index score for that category is above the threshold. The interest profile is adjusted by applying a decay to those interest index scores associated with time stamps determined for the categories.

Computer-implemented system and method for updating user interest profiles

A computer-implemented system and method for generating an interest profile for a user from user generated content on existing online profiles is provided. Interest categories are maintained in a database and each interest category is associated with an initial interest index score. User generated items are selected from an existing online profile and each user generated item is associated with a weight. For each user generated item, similarity mapping is performed with each of the interest categories in the database by extracting artifacts from each user generated item, calculating an artifact similarity score for each of the extracted artifacts, obtaining a user generated item similarity score for the user generated item, and determining a current interest index score for the user generated item. An interest profile for the user is generated by applying the current interest index score to the interest category.
