Semantic modeling technologies, such as RDF, can help ease the problem of automatic reasoning between different data sets, provided that it is built-in to the data-store.

语义建模技术，例如RDF，可以帮助简化对不同数据集之间自动进行推理所面临的问题，这些数据集是内嵌在数据存储介质中的。

Legacy data sources are likely to require much human effort in terms of analysis and data cleansing before they can be availed to semantic modeling technologies.

对于传统的数据源来说，通常需要投入大量人力物力，进行分析和数据净化工作，然后才能将其用于语义建模技术。
