BBN: description of the PLUM system as used for MUC-3

چکیده
Traditional approaches to the problem of extracting data from texts have emphasized handcrafted linguisti c knowledge. In contrast, BBN's PLUM system (Probabilistic Language Understanding Model) was developed as part of a DARPA-funded research effort on integrating probabilistic language models with more traditiona l linguistic techniques . Our research and development goals are • more rapid development of new applications , • the ability to train (and re-train) systems based on user markings of correct and incorrect output , • more accurate selection among interpretations when more than one is found, an d • more robust partial interpretation when no complete interpretation can be found .

متن کاملBBN PLUM: MUC-3 test results and analysis
Perhaps the most important facts about our participation in MUC-3 reflect our starting point and goals . In March, 1990, we initiated a pilot study on the feasibility and impact of applying statistical algorithms in natura l language processing. The experiments were concluded in March, 1991 and lead us to believe that statistica l approaches can effectively improve knowledge-based approaches [W...
متن کاملBBN: Description of the SIFT System as Used for MUC-7
For MUC-7, BBN has for the first time fielded a fully-trained system for NE, TE, and TR; results are all the output of statistical language models trained on annotated data, rather than programs executing handwritten rules. Such trained systems have some significant advantages: • They can be easily ported to new domains by simply annotating data with semantic answers. • The complex interactions...
متن کاملBEN: description of the PLUM system as used for MUC-6
ABSTRAC T This paper provides a quick summary of our technical approach, which has been developing since 1991 and wa s first fielded in MUC-3. First a quick review of what is new is provided, then a walkthrough of system components. Perhaps most interesting is out analysis, following the walkthrough, of what we learned through MUC-6 and o f what directions we would take now to break the perform...
