Textual chunk retrieval and packing in pattern

Pattern technology of writing is widely used in machine writing systems. In pattern technology, there are two core issues about chunk as writing material in the pattern. One is chunk retrieval, the other is chunk packing. In this study, we focus on the problem of chunk retrieval and packing with given style, topic and content of practical writing. We proposed the concept of chunk, and discussed the method of chunk retrieval in context. Then we studied the approach of chunk packing. Differ from general packing problem, chunk packing is affected by several special factors: stylistic features, writing model, literal semantic and etc. These require the intelligence of human. Thus our chunk packing approach is based on man-machine cooperation genetic algorithm. The man-machine cooperation approach can realize the integration of the human and the machine to finish the writing process.
