چکیده

Traditional approaches to the problem of extracting data from texts have emphasized hand-crafted linguisti c knowledge . In contrast, BBN's PLUM system (Probabilistic Language Understanding Model) was developed a s part of a DARPA-funded research effort on integrating probabilistic language models with more traditional 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.

BBN 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...

BBN: 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...
