| Abstract: | Through comparing information retrieval with information extraction in terms of published paper, conferences, access and output points, key technique and development trend, the paper finds that there is radical difference between information extraction and information retrieval and that information extraction can not stand for the direction of information retrieval, but this type of technigue can be applied into information retrieval system. Analyzing differences between them will foster further research, and exploring their relation will be beneficial to their mutual development. |
