Web applications are increasingly showing recommended users from social media along with some descriptions, an attempt to show relevancy-why they are being shown. For example, Twitter search for a topical keyword shows expert twitterers on the side for `whom to follow'. Google+ and Facebook also recommend users to follow or add to friend circle. Popular Internet newspaper-The Huffing ton Post shows Twitter experts on the side of an article for authoritative relevant tweets. The state of the art shows user profile bio as summary for Twitter experts, but it has issues with length constraints imposed by the user interface (UI) design, missing bio and sometimes funny profile bio. Alternatively, applications can use human generated user summary, but it will not scale. Therefore, we study the problem of automatic generation of informative expertise summary or taglines for Twitter experts in space constraint imposed by UI design. We propose three methods for expertise summary generation: Occupation-Pattern based, Link-Triangulation based and User-Classification based, with the use of knowledge-enhanced computing approaches. We also propose methods for final summary selection for users with multiple candidates of generated summaries and evaluate results by user-study for both generation and selection tasks. The results of proposed tagline generation methods show 92.8% good summaries with majority agreement in the best case and 70% in the worst case while outperforming the state of the art up to 88%. This study has implications in the area of expert profiling, user presentation and application design for engaging user experience.
