A system, method or computer readable storage device to derive a taxonomy from keywords is described herein. A domain-dependent taxonomy from a set of keywords may be automatically derived by leveraging both a general knowledgebase and keyword search. For example, concepts may be deduced with the technique of conceptualization, and context information may be extracted from a search engine. Then, the taxonomy may be constructed using a tree algorithm.

Automatic taxonomy construction from keywords

Visualizing content change of a data collection over time. A topic may be split into multiple linear, non-overlapping sub-topics along a timeline by satisfying a diverse set of semantic, temporal, and visualization constraints simultaneously. For each derived sub-topic, a set of representative keywords may be automatically selected to summarize the main content of the sub-topic.
