An approach toward functional text structure analysis of scientific and technical documents

摘要

An approach toward a functional structure analysis of abstract text is presented as a part of a semantic information representation method of scientific and technical documents. This analysis method forms a fundamental study on construction methodology of an advanced document information system together with an extraction method of semantic information in the text. As “information functions” in the abstract, four concepts of Theme, Method, Result and Discussion are selected and a model set of “functional patterns” consisting of meta-terms in each sentence of the abstract is prepared. A preliminary computer experiment is implemented with a pattern matching procedure identifying the information function for each sentence of the abstract based on the model set. The results are examined and discussed in terms of reproducibility of the model set and effectiveness of the procedure for the other data sets. The procedure is evaluated showing some validity as a whole and suggestions for future improvements are given.
