The beginning
 INTEX was included in the curriculum of
the Master`s programme in
Computational Linguistics in the
academic year 2001-2002.
http://compling.ibl.bas.bg
 INTEX is used in teaching the subject
Computer Systems for NLP.
6th INTEX Workshop, Sofia 28-30 2003
Main goals
 To expand the students competence on
formal linguistic representation.
 To help students in grasping the
theoretical complexity and the scope of the
linguistic phenomena.
 To develop the students competence on
finite state automata and their application
in natural language processing.
6th INTEX Workshop, Sofia 28-30 2003
Standard tasks for all students
 Enhancing the existing Sentence
boundaries delimiting FST
 FST-s for the analytic cardinal and ordinal
numerals in Bulgarian
 FST-s for dates – Latin and Arabic
numbers
6th INTEX Workshop, Sofia 28-30 2003
Individual tasks
 DELAF and DELACF dictionaries for:
historical periods and events,
institutions` names, companies` names.
 DELAF and DELACF dictionaries for:
chemical compounds terms,
botanical and zoological terms, toponyms,
abbreviations.
6th INTEX Workshop, Sofia 28-30 2003
Individual tasks
 DELACF dictionary of phraseologisms.
 DELACF dictionary of frozen expressions
 Decision-making in presenting the
paradigms
6th INTEX Workshop, Sofia 28-30 2003
Some examples
 Modifier + Noun head
Carbon dioxide
въглероден диоксид,въглероден
диоксид.N+M:s
въглеродния диоксид,въглероден
диоксид.N+M:sh
въглеродният диоксид,въглероден
диоксид.N+M:sl
6th INTEX Workshop, Sofia 28-30 2003
Some examples
 metal oxide:
метален оксид, метален оксид.N+M:s
металния оксид, метален оксид.N+M:sh
металният оксид, метален оксид.N+M:sl
метални оксиди, метален оксид.N+M:p
металните оксиди, метален оксид.N+M:pd
6th INTEX Workshop, Sofia 28-30 2003
Individual tasks
 FST-s for the analytic forms of the grammatical
paradigms of verbs, nouns and adjectives.
 FST-s for recognition of analytic verb forms in
the indicative mood, active voice. These are the
present perfect, pluperfect, future, future perfect,
future in the past, future perfect in the past.
 At the present moment the students develop
FST-s for the passive voice of the indicative
mood of all tenses, for conditional mood forms of
all tenses.
6th INTEX Workshop, Sofia 28-30 2003
Individual tasks
 A particular case is the negative tensed
forms because the negative forms are
always analytical and FST-s are devised
for tenses which have otherwise synthetic
formation. Negation patterns and question
patterns have particular word order which
has to be considered, too.
 Some examples
6th INTEX Workshop, Sofia 28-30 2003
Future Perfect in the Past in
Bulgarian
6th INTEX Workshop, Sofia 28-30 2003

6th INTEX Workshop, Sofia 28-30 2003
Tasks
 Expansion of the existing linguistic corpus
 Notations unification
 Devising of bigger and richer libraries of
dictionaries and FST-s
6th INTEX Workshop, Sofia 28-30 2003
Masters` theses
 A master's thesis was written on
representation of Bulgarian compound
nouns in INTEX.
 This year students are going to use INTEX
for analysis of recognition errors for
Grammar checker
OCR correction.
6th INTEX Workshop, Sofia 28-30 2003
Future directions
 Introducing a wider range of Bulgarian
researchers to INTEX.
 Applying INTEX in a wider range of
activities.
 Enhancing the system with more
resources.
 Cooperation in expanding the
functionalities of INTEX.
