Is Tag Cloud Helpful? ,[object Object],[object Object],[object Object],[object Object]

An Example of Browsing (CiteULike) ,[object Object],[object Object],1. information  2. retrieval  3. algorithms  4. phylogeny

Users’ Conceptualizations ,[object Object],[object Object],The journey … switching direction and being stack The space … increasing distance, and continuity 18 participants

Research Questions ,[object Object],[object Object],[object Object]

Recall : Example of Navigation (CiteULike) 1. information  2. retrieval  3. algorithms  4. phylogeny

User Interface with “History tag clouds” (Tag Trails) Supporting continuity in tag-space navigation by providing history information  retrieval  algorithms  phylogeny History tag clouds

User Interface with Heat map (Tag Trails 2) ,[object Object],Tag cloud Results list Column-tags: most recently visited tags from left to right Row-tags: selection of most frequent tags Cells color-coded according to tag’s df Heat map
