3. Machine Translation (MT) Component technologies Comparable technologies Composed technologies

4. MT--Purposes Dissemination (high quality) sublanguages, controlled languages Assimilation (broad coverage) Communication (speed)

5. MT -- Types Direct – string-for-string Transfer – structure-for-structure Interlingual – to and from a meaning representation Statistical – most probable translation given a corpus

6. Component technologies -- I Character encoding and representation, text editing (Unicode) Text segmenting (OCR, sandhi?) Morphological analysis Lexical annotation (part of speech tagging, proper name identification, others)

7. Component technologies -- II Syntactic analyzers (grammars, parsers) Bilingual/multilingual dictionaries Ontologies (WordNet, OntoSem, Cyc)(lexical, linguistic, world-knowledge) Generation systems

8. Comparable technologies Information Retrieval (IE) (URSA) Information Extraction (IR) (MUC) Text Summarization (DUC) Word Sense Disambiguation (SensEval) Cross-Document Named Entity Identification (Coreference Resolution)

9. Composed Technologies All of the above (IR/IE/Summarization) multi-lingual multi-modal with attention to human-computer interaction (HCI)

10. Composed technologies -- II Personal Profiler – searches the web to find information about a particular person, translates it if appropriate, and organizes in temporal order Quick Ramp-up MT (Expedition) – allows a non-linguist language user and a computer expert to construct a simple MT system

11. Question-Answering Systems Advanced Question and Answering for Intelligence (AQUAINT) MOQA – Meaning-Oriented Question Answering Allows user to pose structured or natural language queries, obtains answer from a variety of sources, and presents the answer appropriately
