... An Improved Error Model for Noisy Channel Spelling Correction Abstract The noisy channel model has been applied to a wide range of problems, including spelling correction. These models consist of ... components: a source model and a channel model. Very little research has gone into improving the channel model for spelling correction. This paper describes a n...

... (entity- mention model) a good classifier learner for the mention-pair model. The fifth line of Table 4 is for the ILP based entity- mention model (described in Section 4.2). We can observe that the model ... (up to 1.8% for BNews), the gain in the precision could compensate it well; it beats the MP model in the overall F-measure for all three domains (2.3% for Nwire, 0.4%...

For the ex- periments described below we trained an exponen- tial model...

At this point, only one split is left for ... by checking each split for eliminability before it is added to the chart. We compare the performance of this algorithm to the baseline of computing the complete chart. For comparison,...

To cope with the limitation, there is an algo- rithm proposed for Japanese ... algorithm which can correct both word spacing error and spelling error simulta- neously for Korean. This algorithm is based on noisy- channel model, which uses Jaso 3...
