CLARIN is a European Research Infrastructure providing access to digital language resources and tools from across Europe and beyond to researchers in the humanities and social sciences. This paper focuses on CLARIN as a platform for the sharing of language resources. It zooms in on the service offer for the aggregation of language repositories and the value proposition for a number of communities that benefit from the enhanced visibility of their data and services as a result of integration in CLARIN. The enhanced findability of language resources is serving the social sciences and humanities (SSH) community at large and supports research communities that aim to collaborate based on virtual collections for a specific domain. The paper also addresses the wider landscape of service platforms based on language technologies which has the potential of becoming a powerful set of interoperable facilities to a variety of communities of use.

We argue for the necessity of studying human-human spoken conversations of various kinds in order to create user interfaces to databases. An efficient user interface benefits from a well-organized corpus that can be used for investigating the strategies people use in conversations in order to be efficient and to handle the spoken communication problems. For modeling the natural behaviour and testing the model we need a dialogue corpus where the roles of participants are close to the roles of the dialogue system and its user. For that reason, we collect and investigate the Corpus of the Spoken Estonian and the Estonian Dialogue Corpus as the sources for human-human interaction investigation. The transcription conventions and annotation typology of spoken human-human dialogues in Estonian are introduced. For creating a user interface the corpus of one institutional conversation type is insufficient, since we need to know what phenomena are inherent for the spoken language in general, what means are used only in certain types of the conversations and what are the differences.
