1. Introduction

1.1 The working paper HSEIWP96.2, ""Theory-Neutral" Syntactic
Tagging of the Text," presents a brief outline of the encoding
scheme and indicates the theorizing behind it. This paper,
HSEIWP96.4, is the sister of HSEIWP96.3, "On the Syntactic
Encoding of the Text," which examines choices in implementation
of phrase-structure parsing and assignment of syntactic case. It
was thought useful to separate out the semantic case or
"functions" for independent consideration here in HSEIWP96.4.

1.2 These three working papers, together with the independent
work by Kirk Lowery, HSEIWP96.1, which introduces the Encoding
project and its goals, constitute a basic documentation package
to accompany the HSEI texts, initially of Jonah with the four
books of Samuel-Kings to follow.

Part I: Assignment of Semantic Functions

1. Source of Function Labels and Initial Characterizations

1.1 To date, the source of the semantic tags has been Kirk
Lowery's paper, "The Role of Semantics in the Adequacy of
Syntactic Models of Biblical Hebrew," pp. 101-128 in Bible and
Computer: Desk and Discipline: The Impact of Computers in Bible
Studies: Proceedings of the Fourth International Colloquium of
the Association Internationale Bible et Informatique (AIBI),
Amsterdam, 15-18 August 1994 (Travaux de Linguistique
Quantitative, no. 57; Paris: Honore Champion, 1995):

agent
benefactive
experiencer
goal
instrument
location
patient
percept (with experiencer)
recipient
source
theme

circumstance
comitative
direction
duration
frequency
cause
manner
path
purpose
quality
time
reason

1.2 This scheme appears to strike a balance between fine- and
coarse-grained approaches to Biblical Hebrew semantic functions.
The goal is to apply the labels in a consistent fashion so that
they can be easily manipulated by the discrimating functionalist
scholar.

1.3 In initial attempts to tag Jonah and fragments of other
texts, the semantic roles where the most difficult to assign
confidently and systematically. I have adopted a series of formal
rules to aid the encoder in this more difficult area of tagging,
which are now outlined. It is hoped that such rules might be
developed into lexical "features" of verbs; and that such a
lexicon could be invoked in the envisioned unification-based
parsing of the text.

2. Lexical Rules (Verbal Case Frames)

2.1 Verbs of Motion. The theme tag is reserved here
strictly for the constituent in motion; this may be the argument
of the verb, e.g., hlk, or independently motivated by
prepositions such as el "to." The theme may be the subject ;
or the object , in which case the subject is the agent .
There are therefore two schemas. Here as elsewhere the question
of the redundancy of the syntactic case assignment arises.

(a)

(b)

2.2 Verbs of Cognition. The paired functions "experiencer"
and "percept" are reserved for verbs of cognition. It
is expected that typically will be associated with the
subject position .

2.3 Verbs of Speech. These verbs are not assigned semantic-
functional labels, only for speaker,
for content, and
for the addressee.

2.4 Verbs of Exchange. Under the interpretation of "theme"
adopted, i.e., the constituent in motion, that which is exchanged
is analyzed as a theme. The subject will necessarily be an agent
. The goal is marked "recipient" and associated with
dative assignment . In summary, verbs of exchange pattern
similarly to verbs of motion.

3. Formal Rules

3.1 Purpose is automatically assigned to the headed by

l- "to" which in turn governs the .

3.2 Why/Reason is assigned to the ki- as default. The

9al "on" in 9al ken "therefore" automatically triggers .
The complex construction with be-$el-l-mi is assigned as
well.

3.3

s are assigned as a default.

3.4 A headed by ka'a$er triggers "manner."

3.5 The

9al triggers by stipulation in its sense of
"versus."

3.6 The

9im "with" is assigned .

Part II: Critical Consideration of the Semantic Encoding Scheme

4. Adequacy of Scheme

4.1 The scheme as applied to the text of Jonah does not present
any insurmountable difficulties. Nevertheless, scholars using the
database would be well advised to consider the slipperiness of
the semantics in working with the results of searches.

4.2 It seems unlikely that the full range of semantic tags would
be required for automated parsing. However, there is the question
of the relative order of verbal modifiers; and the more fine-
grained scheme here should facilitate testing hypotheses in this
domain.

5. Redundancy and Decomposition

5.1 Redundancy and the Lexicon. There appears to be a great deal
of redundancy at the lexical level. Individual

s appear to be
redundantly associated with semantic tags, e.g., the

9im
"with" and the function "comitative." Such observations
extend to the arguments of verbs as noted in section 2 above.
Given the verb is, e.g., yd9 "to know," the subject is
redundantly tagged "experiencer."

5.2 Such observations, however, hold out hope for automated
tagging. Lexical entries could in some fashion bear semantic
"features" that could be used in assigning semantic "functions."

5.3 Consideration of a lexicon and its structure suggests that
many of the semantic-function labels are not "primitives" but are
subject to decomposition. The label "purpose," e.g., appears
to be a function of a particular

, l- "to" as noted in section
3 above.

5.4 Such considerations suggest that groups might be related
systematically at a more primitive level. No doubt "time,"
"duration," and "frequency" could be so related;
indeed, may be the primitive, the others derived by
composition.

5.5 The basic suggestion is that individual heads introduce
semantic features into representations by virtue of their lexical
representations. These features can percolate and interact with
features and syntactic configurations to produce the ultimate
assignment of "function" to a given .

5.6 An example might be the assignment of "time" to bre$it
in Genesis 1:1. Under the null hypothesis, b- "in" might be
assigned by default, but otherwise remain unmarked. On the
other hand, re$it will bring with it the feature by virtue
of its semantic lexical entry. The proposal can be graphically
represented in (a) and (b).

De Mens - Metafoor

(Beth HaMidrash)


In de discussie, Goddelijke relativiteit ten opzichte van het Universum, is de favoriete metafoor van de mystici (ook vele filosofen) de analogie tot de mens. Theologische concepten en de G`D-wereld verhouding, zijn vaak uitgelegd in termen van ziel-lichaam verhouding, en in het bijzonder met de vergelijking van de verschillende ziel-gaven, hun eigenschappen, functies en manifestaties. De ‘bewijstekst’ voor dit taalgebruik is het vers ‘Vanuit mijn vlees voorzie ik G`D’ (Job 19:26) en de Rabbijnse analogie “Juist zoals de ziel doordringt het hele lichaam. ziet maar is niet gezien……ondersteund het hele lichaam…..is zuiver…..verblijft in de binnenste omgeving……is uniek in het lichaam….doet niet eten noch drinken…..geen mens weet waar zijn plaats is…… Dat de Heilige die Een is, geprezen zij Hij…” Ook dit in bepaalde zin volgt het bovengenoemde principe van een ‘aards-bovennatuurlijke overeenkomst’.

Maar zelfs als tijdelijk begrippen van de ziel behulpzaam zijn om kwesties te begrijpen die gerelateerd zijn aan het Goddelijke, dan is dit maar een antropomorfistische benadering welke niet te ver mag gaan, zo nodig beperkt.

Het moet onthouden worden, zoals R. Schneur Zalman karakteriseert, dat in sommige opzichten de analogie instort en compleet ontoereikend is: “Deze parallel is alleen ter bevrediging van het oor. In werkelijk echter, heeft de analogie geen enkele overeenkomst tot het vergelijkbare oogmerk. Want de menselijke ziel… is geaffecteerd door de accidenten van het lichaam en zijn pijn. terwijl de Heilige die Een is, geprezen zij Hij, niet, de Hemel verbied, is geaffecteerd door de accidenten van de wereld en zijn veranderingen, noch door de wereld zelf; zij bewerkstelligen geen enkele verandering in HEM…..”. Evenzo, “De ziel en het lichaam zijn in werkelijkheid verschillend van elkaar, van uit hun absoluut bron gezien, want de bron van het lichaam en zijn essentie komen niet in tot– zijn–vanuit de ziel…”. Dus terwijl het lichaam volledig ondergeschikt mag zijn aan de ziel, zijn er, niettegenstaande, twee verschillende entiteiten. In contrast, “in relatie tot De Heilige die een is, geprezen zij Hij, die alles tot existentie brengt ex nihilo, is alles absoluut genullificeerd, net zoals het licht van de zon is genullificeerd in de zon zelf”. M.a.w. licht is niets vergeleken tot zijn bron.
