SUMMERSCHOOL "ARTIFICIAL INTELLIGENCE AND INFORMATION SYSTEMS: INTEGRATION ASPECTS 31.8.1997
Outcome Achieved Date of Achievement
A summer school was organised as the Seventh Advanced Course in Artificial Intelligence, ACAI-97, 23-28.6.1997. It was organised under auspices of European Coordinating Committee for Artificial Intelligence (ECCAI). 23-28.6.1997
Activities Carried Out Dates of Activities
  1. Preparing, advertising, organising and reporting ACAI-97. Communication with invited lecturers and ECCAI.
1.9.1996-31.8.1997
  1. From the Tempus Mobility Grant four lectures were invited to give invited talks: Dr. Finn V. Jensen (Aalborg University), Bertram Ludäscher (Universität Freiburg, Germany), Dr. Robert L.W. van de Weg (University of Twente), and Prof. Matthias Jarke (Rheinisch-Westfälische Technische Hochschule Aachen, Germany).
 21-29.6.1997
Explanation
  1. The idea to combine a summer school with ACAI-97 was proposed by initial contractor and former ECCAI chairman Prof. Nicolaas Mars. This idea was also supported by ECCAI and its chairman Prof. Wolfgang Wahlster. Thus for the first time ACAI was organi sorganised in Eastern Europe. The idea was very good.
  2. Organising a summer school as an international event was very positive. It served to the dissemination of Tempus experience.
  3. ECCAI provided 1000 ECU for a travel grant programme for doctoral students. Four non-Tempus students from non-partner universities were supported.
  4. Lithuanian Science and Study Foundation provided 6000 Litas. This money was used for travel grants of invited lecturers E.Z. Lyubimskii (Moscow) and G.L. Perevozchikova (the Ukraine) and for organisational expenses.
  5. Dr. Finn V. Jensen arranged a donation from Aalborg University of 30 books. The books were used initially by course participants and then distributed to eligible universities. Money for books was from Aalborg University, but not from the Tempus budget.
  6. ACAI-97 was a non profit event, and no financial surplus was received. Most participants were from Lithuania, from Tempus partner universities.

Explanation
  1. The development of the information system at the Faculty of Mathematics of Vilnius University is a continuos process. It is continued from 1995/96 and will be continued in 1997/98 .
  2. The implementation and maintenance of the information system is being done by a student team at the computer laboratory. The students are supervised by teachers. The aim of this Activity is the learning process of Lithuanian students and their supervisors (teachers).
  3. A home page of the Tempus project is at the URL http://www.maf.vu.lt/
    projects/jep09752.htm .

  1. Project Coordination

2.1. The day-to-day management of coordinating the project activities was provided by Lithuanian members of Steering Committee: (1) administrator - docent Dr. Vytautas Cyras and assistant professor Ms. Kristina Lapin, (2) coordinator, Dean of the Faculty of Mathematics - docent Dr. Ricardas Kudzma, (3) local coordinator for Vilnius Technical University - docent Dr. Olegas Vasilecas, (4) local coordinator for the Institute of Mathematics and Informatics - docent Dr. Albertas Caplinskas, and (5) Head of t he Department of Informatics at MaF - docent Dr. Antanas Mitasiunas. The communication with Western local coordinators was permanent - they were informed about major events. In order to run the project, the communication via e-mail, mail and fax with con tact persons at Western partner universities was essential: secretary Ms. Els Bosch and finance officer Mr. Mark Kroep at the University of Twente, secretary Ms. Vivian Jonassen at Aalborg University, and researcher Dr. Georg Strobl at the Technische Uni versitaet Muenchen. Communication via e-mail was essential in order to run the project.

Organisational meeting of project partner representatives on 4-6.10.1996 in Vilnius was very worthy.

2.2 Reduction of teaching duties for some of the key persons of the project was very positive for the coordination of the project. This should be also the case in 1997/98.

The average duration of teacher stays East-West and West-East was shorter than planned in the original proposal. Eastern teachers prefer to stay abroad for about a month. The main reason are teaching duties at home. Western teachers can not afford to sta y longer than a week.

Inviting lecturers from Western universities that are not project partners was very worthy. A written consent from ETF on 28.8.1996 reached project administrator directly. Such a consent from ETF to invite 4 lecturers in 1997/98 is needed once again.

2.3. Bank transfers from the contracting university to partner universities was not so smooth and fast as expected. The reason is a very long chain of stages in communication: administrator - contractor - finance officer - finance office of the contracti ng university - a bank - a recipient's bank - the bank account of the partner university - Tempus recipient.

  • Functioning of the Network

    • The partner network is functioning well. Each partner acts in the role he can do the best. This ensures, that the project meets the needs of the partner country participants. The roles of partners in 1996/97 can be described as follows:

    1. Vilnius University - general coordination and administration, providing place for the courses and a summer school ACAI-97, major part of a teaching laboratory, selecting students for teaching periods T1 abroad;

    2. Vilnius Technical University - organising the tax exemption, part of teaching laboratory;

    3. Institute of Mathematics and Informatics - writing a textbook, selecting a doctoral student for T1 teaching period abroad, proposing lecturers for a summer school ACAI-97;

    4. University of Twente - Contractor (until the contractorship change in spring 1997), accepting Eastern teachers;

    5. Aalborg University - Contractor (after the contractorship change in spring 1997), accepting Eastern teachers and students (Aalborg agreed to accept more than planned in RBAP 1996/97 !);

    6. Technische Universitaet Muenchen - accepting Eastern teachers and students, finding lecturers to give courses of excellent quality in Vilnius (thanks to Prof. Eike Jessen !).

  • Activities and Outcomes

    • 4.1 Restructuring/creation of unit/institution
    The teaching laboratory that was created in 1995/96 was enlarged with computers, software and books. The laboratory is within the Faculty of Mathematics of Vilnius University. The teaching laboratory provides computer facilities for students. The laborat ory provided computer facilities during a summer school ACAI-97. The laboratory serves also as a classroom.

    All the equipment that is purchased for Vilnius Technical University is installed there at one unit - Information Systems Laboratory at the Faculty of Fundamental Sciences. The laboratory provides computer facilities for students. The support of a newly introduced master programme is emphasised.

    4.2 Curriculum Development
    The extent of the academic and institutional support for the curriculum development activities was good. New/restructured courses are recognised at the level of institutions (Vilnius University, Vilnius Technical University, and Institute of Mathematics and Informatics). About 300 students are targeted at VU, about 150 at VTU, and about 10 at IMI. The new/restructured courses are delivered in Lithuanian. They can be delivered in English, but currently no need exists. In case the exchange of students gro ws, the restructured courses will be delivered in English.

    4.3 Teaching materials
    Two original textbooks in Lithuanian are in the stage of development. They will be finished in 1997/98. Staff costs for academic tasks will be paid when the textbooks are in print. A. Caplinskas continued to write the second part of the book "Fundamental s of Software Engineering". Teachers from VU and VTU continued to prepare a textbook on Information Systems. Some materials for the textbooks were adapted during T4 stays of authors at partner universities.

    Aalborg University donated 30 copies of the book by Finn V. Jensen "Introduction to Bayesian Networks". These books were purchased from other sources than Tempus. The books were used during the summer school ACAI-97 and are distributed to eligible instit utions.

    4.4 Staff development
    The teachers for retraining/updating T4 were selected, who deliver the courses targeted to restructure in the Tempus project. The outcome of staff retraining was very positive. The staff obtained experience in many aspects: international cooperation, lan guage development, work in operating system UNIX, etc. The retraining/updating stays were combined with the staff retraining plans of beneficiary institutions (VU, VTU, IMI). Thanks to the Tempus project, the staff of beneficiary institutions obtained a possibility for retraining at western partner universities. Benefits derived from staff retraining are disseminated as follows:
    - retrained teachers disseminate their experience among their colleagues;
    - teaching materials are distributed to other institutions;
    - talks at the Tempus validation seminar in Riga, Latvia; new international events were organised.

    4.5 Student Mobility
    Students for East-West mobility were selected in accordance to the following criteria: (1) knowledge of Danish or German, (2) earlier visits to Roskilde Computer Science College, (2) good academic achievements in carrying out group work projects that wer e delivered in Vilnius by lecturers from Aalborg University, (3) academic recognition by Lithuanian universities of courses to be undertaken at Aalborg University and TU Muenchen.

    Agreements between project partners are at the verbal level. Academic recognition in Vilnius was based on exam marks obtained by Lithuanian students at Aalborg University and TU Muenchen.

    Students involved in the mobility were really good students and surely above the average level. Exam marks prove this fact. Three students, who stayed at Aalborg University, extended their stay there in 1997/98, but from other sources than Tempus. One of these students plans Ph.D. studies at AAU.

    4.6 Equipment
    Equipment purchased is appropriate to the needs of the beneficiary institutions - Vilnius University and Vilnius Technical University. No special training was needed. The principal equipment items were personal computers. VU and VTU installed the equipme nt without the aid of external organisations. Seller "Informacines Technologijos" aided the installment of software from Oracle. Staff of VU and VTU maintains the equipment. Equipment purchased is registered in inventory lists. The main part of books pur chased is registered and kept at the library of MaF VU. Photocopying machines and printers are especially appropriate to the needs of the beneficiary institutions. They enabled a smooth running of the project and a summer school.

    Equipment is used by students and teachers. The equipment is used for learning, teaching, writing textbooks, development of information system, for organisational tasks, etc.

    The tax exemption procedure in Lithuania is carried out at the Ministry of Finances. The procedure is complicated. The Ministry requests many documents from VU and VTU. This bureaucracy requires much more human recourses from staff involved in Tempus tha n initially expected.

  • Conclusions

    • 5.1 The key successes of the project is the development of:
    - contacts and international goal oriented teams, members of which can trust each other;
    - staff, that is able to take part in international events and projects;
    - students, that are able to use new schemes to obtain their education;
    - master programmes and restructured courses.

    The reasons for the key successes are the following:
    - partners are motivated and interested in the successes;
    - students involved in the mobility have intelligence that is above the average student level.

    Shortcoming: financial support from Lithuanian organisations is not as large as expected.

    5.2 Cooperating partners saw the situation at each site. Therefore the partners know what they can expect from each other. The gratifying aspect is that Western partners involved very intelligent teachers. One of the causes for difficulties in the intern ational cooperation is, that Eastern and Western societies face different problems.

    5.3 Involvement of professors from EU universities, that are not Tempus partners is worthy. A written consent from ETF to invite a limited number of such professors should be given directly to Coordinator. The same with money transfer from Mobility to Or ganisational Grant equipment item.

      1. Exchange losses at the University of Twente were caused by contractorship change to Aalborg University. The second Tempus installment 57 150 ECU was first transferred to the University of Twente and then to Aalborg University. The difference in r ate is 1943.10 Fl (950 ECU):
        • credit to the University of Twente from ETF, Torino, 24.12.1996, was 123 644.03 Fl
        • debit from the University of Twente to Aalborg University, 27.5.1997, 125 587.13 Fl
      		 950
      1. Exchange losses at Aalborg University were caused by the transfer of the second installment 57 150 ECU from the University of Twente. The University of Twente transferred 57 150 ECU. Aalborg University received 56 944.81 ECU. Thus exc hange losses are 205 ECU.
      		 205
      1. Exchange losses at Vilnius University were caused by ECU/litas rate. The calculation of expenditures at Vilnius University in Lithuanian litas was made under official ECU/litas rate. The actual price that was paid by East-West staff and students to by the equivalent of 1 ECU in cash or travel cheques (in Dutch guilders, Danish krona or German mark) when paying in litas was up to 5% more.
