Time series, Inverse query, Visual Window query, TW-index.
The paper discusses visual window query of time series data, and presents a new index technique——TW-index. The methods of establishing TW-index and search algorithm are described. The special techniques of implementing TW-index are introduced when data are appended dynamically. The data structure of implementing TW-index is proposed. Finally, the feasibly of TW-index applied in visual window query of time series is proved by the experiment examples.
