Information Extraction of Strategic Activities Based on Semi-structured Text

摘要

The paper constructed the information extraction method to extract description characteristic of execution process from the description text to provide data support for the evaluation of enterprise strategy execution effectiveness. The constructed information extraction method included two stages, i.e., Feature information extraction and information integration. It overcame some weaknesses of the current information extraction technology, such as its mere use for extracting time, address and other named entities. Firstly, the information extraction process of descriptive information is designed through establishing substantial GATE vocabularies and compiling ordinary and special extraction rules to avoid the disadvantages of the identification of GATE in Chinese named entity. Then, rules of integration of description characteristics information are established on the basis of semantic relation, positional relation to structurally represent the process of executing strategic activities.
