About

TweetUM is the Twitter-based User Modeling Framework developed by the Web Information Systems group at TU Delft. It features a set of strategies that allow for semantic enrichment of Twitter messages (tweets) and relates tweets to external (Semantic) Web resources. TweetUM offers functionality such as entity recognition or discovery of relations between entities. Based on enriched tweets, it provides a variety of user modeling strategies that are applied for various applications such as personalized news recommendations. Some TweetUM highlights:
  • semantic enrichment by linking tweets with (Semantic) Web resources
  • user modeling with temporal dynamics
  • TUMS Web service makes TweetUM features available to other Web applications
  • personalization based on TweetUM: news recommendations, personalized faceted search

Datasets

With TweetUM, we have monitored - since November 15th 2010 - more than 20,000 users over a period of more than four months. Overall, we collected more than 30 million tweets and processed them with the TweetUM enrichment and user modeling pipeline. Subsets of this dataset are available online: datasets

TUMS: Twitter-based User Modeling Service

The Twitter-based User Modeling Service (TUMS) allows end-users to inspect Twitter-based profiles and enables other applications to re-use these profiles. TUMS is therefore interesting for other services on the Social Web as it enables them to consume Twitter-based profiles in RDF format. Profiles can be used for personalization and are particularly useful for other applications that suffer from sparsity problems (e.g. services that cannot collect sufficient data about their users) and services that are interested in "realtime" or very fresh profile information.

GeniUS: A Generic User Modeling Library for the Social Semantic Web

GeniUS is a generic topic and user modeling library for the Social Semantic Web that enriches the semantics of social data and status messages particularly. Given a stream of messages, it allows for generating topic and user profiles that summarize the stream according to domain- and application-specific needs which can be specified by the requesting party.
