Challenges for Baltic Languages

• Rich structure, inflectivity and complexity of languages

• Relatively small number of speakers, small market

• Few researchers active in HLT, insufficient scientific base

• Lack of specialists resulting from lack of targeted education programs

• Technology gap separating from large languages should be narrowed

• Baltic and EU cooperation is critical• Researchers and industry developers should

target EU programs with joint projects
