In a paper presented at ACH/ALLC 2005, Allen H. Renear describe a problem of potentially great significance (Renear 2005). They argue that:
“In ordinary linguistic communication we often use a name to refer to something in order to then go on to attribute some property to that thing. However when we do this we do not naturally construe our linguistic behavior as being at the same time an assertion that the thing in question has that name. (Ibid, p. 176)”
Further, they claim that this distinction is over-looked
when conceptual models based on encoded texts are
In our work at the Unit for Digital Documentation at the University of Oslo, we have used XML encoded
material as sources for several of our databases (Holmen
1996, Holmen forthcoming). The way this is done is by marking up texts both descriptively and interpretatively, followed by the use of software to extract information which is included in the databases. If Renear’s argument is correct, we may infer that the databases include assertions
which are based on information in the source texts that is, strictly speaking, not grounded in these texts. For example, we could be using a text as the source of a naming in the database while the naming is merely exhibited, and not asserted, in the text.
The false resolutions
Renear propose three possible resolutions to this problem, but they also state that all of these are false. Their resolutions are the following:
1. TEI encoding represents features of the text only 2. The use of two arcs, i.e. “The Semantic Web
community solution”, which will be discussed below.
3. Exhibition is a special case of presupposition.
Based on the description of our work above, it should be obvious that resolution no. 1 is not an alternative for us. Semantic modelling of the real world on the basis of descriptions in texts is part of our work.
I find it difficult to understand how resolution no. 3 may represent a possible solution. Whether exhibition is a type of presupposition or not does not change the basic problem; i.e. in our case, the use of a text as the source of a naming which is merely exhibited in the text. The
problem remains the same if the naming is also presupposed
in the text, as long as it is not asserted.
I claim that resolution no. 2 is not false after all, and
below I will demonstrate how the Conceptual Reference
Model (CIDOC-CRM) will solve a similar problem in my example text. The CIDOC-CRM is a ontology
developed in the museum community to be used for
cultural heritage documentation.
My example text
In this paper, no general solution to the problems
identified above will be proposed. However, I
believe that the special solution that I propose could easily
be generalized.
The text used in my example is based on the work of
Major Peter Schnitler. In the 1740s, Major Schnitler was appointed by the Danish government to explore the border
area between the northern parts of Norway and Sweden/Finland. Significant parts of the text in the manuscript that he handed over to the Danish government consist of transcripts of local court interviews which were carried out by Schnitler in order to gather information about the local population as well as what they had to say about
the border areas. The material includes information
directly relevant to the border question, as well as general
information of the areas in question, which corresponds to similar material collected through work carried out in Europe at the time (Burke 2000, pp. 128 f.).
The text fragments below are taken from the very first meeting described in the text (English translation from Danish by me):
[1] Of the Witnesses, supposed to be the most Cunning on the border issue, Were and stood up in the court 1: Ole Larsen Riise.
[2] For these the Kingly order was read out loud [...] and they gave their Bodily Oath
[3] Question: 1: What his name is? Answer: Ole Larsen Riise (Schnitler 1962, p. 1)
In these quotes, we find that several facts are asserted by the text.
Excerpt 1 claims the existence of a witness. We will call this witness x. Being a witness implies being a person. Thus, x is a person. We may also note that x is referred to by using the name “Ole Larsen Riise.”, abbreviated “OLR” below.
Excerpt 2: Person x gave an oath to speak the truth.
Excerpt 3: Person x, according to the text, claims that his name is OLR. The source of the naming is person x, as spoken out loud at a specified place at a specified date in 1742. The text puts forward an assertion by person x that he is named OLR.
Modelling the semantic content from our perspective
My semantic model of these facts will include the
following information:
1) There is an x who is a witness
The text
2) x is a person
The meaning of the word “witness” and “person” in this context
3) x gave an oath
The text
4) OLR is the name of person x
It is easy to describe the source of the three first
assertions through CIDOC-CRM, by stating that they are documented in Schnitler’s text: In this figure, as well as in the next one, the boxes with names starting with E represents entities, while the boxes with names starting with P represents the properties linking them together.
But how do we describe the source of the naming event? We start with the event in which the attribute was
assigned (the naming event, a speech act), which is an E13 Attribute assignment which states that x carried out this particular speech act:
Figure 2
When looking at these two model figures, it is striking to what extent the modelling of the giving of the oath in Figure 1 compares to the naming of x in Figure 2. The
explanation is that those are similar situations. Our
traditional way of reading made us structure them
differently in the table above, whereas represented in the
CIDOC-CRM structure they came out the same in
Figure 1 and 2. In order to show clearly in what way they correspond, note that line 4 in the table above could be rewritten as follows:
4) x named himself ORL
The text
This is a good example of the way modelling may help us understand a text better. What we have done is to
rethink the difference between an event (x gave an oath)
and a fact (ORL is the name of x). In order to model the fact correctly, i.e. to show that it was exhibited rather
than asserted in the text, we had to consider it as a
naming event. Considering it as an event is more feasible in that an event typically has actors who are responsible for the outcome. Further, this makes more sense in that both expressions are speech acts. When it is considered as a speech act, the naming event is the same kind of event as the giving of an oath.
Why solution 2 is not false after all
In order to be able to see the problem with Renear’s solution no. 2, or to realize that the problem is not really there, we have to quote his text in extensio:
“Another approach, this one anticipated from the Semantic Web community, is simply to insist on an unambiguous corrected conceptual representation: one arc for being named “Herman Melville”, one for authoring Moby Dick. But this resolution fails for the reasons presented in the preceding section.
Although this model would be in some sense an
accurate representation of “how the world is”
according to the document, it would not represent what is asserted by the document. The authorship arc in the corrected RDF graph model will correspond
to relationships of exhibition, not assertion; and there is no accommodation for this distinction in the modelling language. (Renear, p. 178)”
In the first couple of sentences in this paragraph, the
resolution of using an “unambiguous corrected conceptual
representation” is said to have failed. The next couple
of sentences weakens his statement by saying that
only RDF does not accommodate this; “there is no
accommodation for this distinction in the modelling
language” (my emphasis). There are no arguments to support why a different modelling language could not solve the problem. In fact, the CIDOC-CRM does solve this, by giving the modeller an opportunity to state
explicitly who is the source of an assertion, as
demonstrated in Figure 2.
In the example above, we knew who made the assertion exhibited in the text. But even if we did not know, we could still make a similar model as long as we accept
that it was made by somebody. In CIDOC-CRM, the
modelling of entities we infer to exist without knowing who
or what they are is quite possible.
The example described above is quite special, as it includes an explicit naming. But it can be argued that all person names, at least in 18th century Scandinavia, are based on naming events, as people are baptised. As long as we believe that this is the case, we can include in the model an explicit attribute assignment event as the one in Figure 2 for each name used in the text. This will be an event of which we do not know who carried it out or when it took place, but that is not necessarily a
problem. The will always be things we do not know in historical texts. The naming event we model this way will also be an event that is not documented in the text we are basing the model on. Whether this is acceptable is a decision one has to take when building up such a model.
There is reason to believe that the problem described in Renear’s paper is an important one. But a solution to the problem has been identified. I have shown that for
one specific type of text, the problem may be solved by using CIDOC-CRM modelling including explicit
statements of the sources of the assertions exhibited in the text. Further research may disclose whether this
solution will work for other types of texts as well.

The effort to establish ADHO began in Tuebingen, at the ALLC/ACH conference in 2002: a Steering Committee was appointed at the ALLC/ACH meeting in 2004, in Gothenburg, Sweden. At the 2005 meeting in Victoria, the executive committees of the ACH and ALLC approved the governance and conference protocols and nominated their first representatives to the ‘official’ ADHO Steering Committee and various ADHO standing committees. The 2006 conference was the first Digital Humanities conference.
