11. 11
Research topics/questions
1. Comparative empirical study of L2 Estonian and standard Estonian;
automatic processing of written texts of Estonian learner language.
2. Constraints on lexical, morphological and morpho-syntactic
variability.
3. Morpho-syntactic complexity of language use and lexical richness
of learners in order to develop CEFR proficiency level
characterizations, and study how the second language proficiency
develops from one level to the next.
4. Linguistic and language technology modeling of language
proficiency levels, gross-linguistics influence.
5. Written Estonian analysis and it’s perspectives for pedagogical
purposes.

12. 12
The major technical problems currently
1. Some inefficient algorithms and queries for big data.
2. Weak server for bigger use.
3. Relatively slow web access to text analysing tool Estmorf.
Possible solution:
Complete rewriting the code, redesigning the user interface and data
structures.

13. 13
Planned: development of EIC 2.0
1. Self-learning and text analysing platform: statistics, similarities,
groupings, word ordering, faulty text recognition, patterns finding.
2. Connections to learning environments and speller.
3. Training materials and exercises preparation and analyse.
4. Language level analyse, metadata guessing.
5. Interoperability with other language resources.
Additionally: Further development of software applications that are
currently on prototype level – Robust Lemmatizer, Word Order
Finder and Cluster Catcher – and integrating them into an
interoperable web service for determining and testing the linguistic
profile of the language proficiency level, as well for instructing the
independent users.

Data analysis

24. 24
Teaching
Current situation:
• Descriptive statistics (IFI7041.DT, IFI6081.DT)
• Inferential statistics (IFI7044.DT, IFI7070.DT, IFI6082.DT)
• Multivariate statistics (IFI7071.DT, IFI8004.DT, IFI8005.DT)
Curricula development:
• General courses are area specific and they give basic knowledges
for academic learning
• Descriptive statistics IFI7041.DT -> Scientific thinking (general
course)
• More scientific thinking and less software

The request for cooperation
1. Compose an overview of the current stand of R&D in smart houses
(SH).
2. Propose possible joint – between TLU and the CC – R&D activities.
3. Compose an overview of SH solutions currently offered by Estonian
enterprises, and of their possible development trends.
4. Propose ideas/topics to the enterprises for possible joint – TLU,
CC, enterprises – development projects.
5. Propose principles for experimenting and testing new SH solutions.

31. 31
Our approach
Current definition: A smart house (SH) is a house that has highly
advanced automatic systems for lighting, temperature control, multi-
media, security, window and door operations, and many other
functions.
A SH is considered as a technical/technological system (domotics =
home automation).
We consider a SH as a socio-technical system which includes both the
technological systems, as well as people and their interactions.
NB! The focus of the people and on their needs.

32. 32
Our possible contribution
1. Analysis of the development trends and development of new SH
solutions.
2. Adaptation of workplace-based learning solutions for SH context,
taking also into account telework/telecommuting/remote work
(kaugtöö) aspects.
3. Development of interactive solutions that react on behavior (inc
gestures) and physiological data of persons – extension of human-
computer interaction to human-house interaction (HCI  HHI).
