Unformatted text preview: ethods arise. One problem
is that we now have to deal with problems of — from the data modelling
perspective — unstructured data sets.
If we try to deﬁne text mining, we can refer to related research areas. For each
of them, we can give a different deﬁnition of text mining, which is motivated by
the speciﬁc perspective of the area: 22 LDV-FORUM A Brief Survey of Text Mining
Text Mining = Information Extraction. The ﬁrst approach assumes that text min- ing essentially corresponds to information extraction (cf. section 3.3) —
the extraction of facts from texts. Text Mining = Text Data Mining. Text mining can be also deﬁned — similar to data mining — as the application of algorithms and methods from the
ﬁelds machine learning and statistics to texts with the goal of ﬁnding
useful patterns. For this purpose it is necessary to pre-process the texts
accordingly. Many authors use information extraction methods, natural
language processing or some simple preprocessing steps in order to e...
