markers have specific characteristics and can be mapped to different BPMN
constructions. In order to capture this semantic information we compiled four
lists, namely ConditionIndicators (exclusive gateway), ParallelIndicators (paral-
lel gateway), ExceptionIndicators (for Error Intermediate Events), and Sequen-
ceIndicators (for the continuation of a branch of a gateway). These lists do not
claim completeness and can be extended by the user, if necessary.
We can use the information gathered so far to combine the information con-
tained in two different Actions. This procedure tackles the problem of Actions
which are split up over several sentences (Issue 2.2). To consider two Actions as
a candidate for a merger, a reference had to be established between them during
the anaphora resolution phase. This reference can either directly point from the
Actor or from the Object of this Action. But, for the case that the Object points
to another Actor or Resource we also consider the Action which contains it as
a possible candidate. Next, it is checked whether the objects can be merged by
checking various characteristics of both Actions. If the actions truly complement
each other, they can be merged and form one single action. When both Actions
complement each other except for the negation modifier we can still enhance the
information content of one action by copying information, as the initiating Actor,
the Object, and/or the copula attribute. An example for such a case are these
sentences: “Of course, asking the customer whether he is generally interested is
also important.” and “If this is not the case, we leave him alone, [...]”
For Issue 4.2, we defined three types of textual references: forward, backward,
and jump references. In order to identify those links in the text automatically,
we start by comparing all actions within our World Model to one another. It
is then determined whether the selected actions can be linked or not. Within
this method, we compare the following characteristics of both Actions: Copula
Specifier, Negation Status, the initiating Actor (ActorFrom), the Object, the
open clausal complement, and the Prepositional Specifiers, whose head word is
“to” or “about”. The elements are compared using their root form provided by
WordNet. If the elements differ or an element is defined for one Action, but
not for the other, the Actions cannot be merged. Otherwise, the Actions are
considered equal and a link relationship can be established. Additionally, the
type of the link relationship is determined and saved along with the link.
