There are many groups that have different projects and aims.
The first research group i am going to talk about is National Centre for Language Technology of Ireland.

It has different research areas and all of them are related with language processing. 

• CALL Computer Assisted Language Learning:                                                                                                                                                   Integrating CL/NLP/HLT Technology into CALL, CALL for Endangered Languages, CALL for Primary School Environments, CALL for Remedial Learners
• Corpus Linguistics:                                                                                                                                                                                             Collocation, Contrastive Computational Linguistics, Corpus-based Translation Studies.
• Machine Translation and Translation Technology:                                                                                                                                                      Statistical and Rule-Based MT (SMT, RBMT), Example-Based MT (EBMT), Translation Memories (TMs), Boosting Existing MT Systems, Machine-Aided Translation (MAT), Computer-Aided Translation (CAT), Controlled Languages
• Treebank-Based Unification Grammar Acquisition:                                                                                                                                            Automatic Feature-Structure Annotation Algorithms, Subcategorisation Frame Extraction, Wide-Coverage Robust Probabilistic Unification Grammar Acquisition, PCFG-Based LFG Approximation, HPSG Acquisition, Multilingual Treebank-Based Grammar Acquisition
• Semantics:                                                                                                                                                                                                                 Discourse Representation Theory, Linear-Logic Based Semantics, Computation of Logical Forms from Treebanks, Open-Domain Question Answering Systems
• Speech Technology:                                                                                                                                                                                                       Speaker Characterisation, Audio Classification, Retrieval and Coding, Human Computer Interfaces (HCIs)
• Multilingual Information Retrieval/Extraction
• Language Evolution

On the oder hand, in order to create, coordinate and make language resources and technology available, we can find CLARIN.
This research network has many objectives:

• integrated: the resource and service centres are connected via Grid technology and form a virtually integrated domain
• interoperable: the resources and services will be based on Semantic Web technologies to overcome format, structure and terminological differences
• stable: the resources and services are offered with a high availability
• persistent: the resources and services are planned to be accessible for many years so that researchers can rely on them
• accessible: the resources and services are accessible via the web; different access methods and training possibilities are offered tailored to the needs of the communities making use of them
• extendable: the infrastructure is open so that new resources and services can be added easily

Finnaly, I would like to name an spanish associations whose aims are:                                                                                                                             The establishment of channels of exchange of information and scientific materials, the organization of seminars, symposiums and conferences, the promotion of publications and the collaboration with other national or intercional institutions related to his area of action.
