However, such consistency is not followed for sentence & paragraph computation. fts:sentenceDistance() is defined as $tokenInfo2/@startSent - $tokenInfo1/@endSent -1 in section 4.2.4. However, fts:sentenceDistance() is involked in section 4.2.7.9 with fts:tokenInfo is order by ('$fts:tokenInfo/@startPos, fts:tokenInfo/@endPos) instead of ($fts:tokenInfo/@startSent, fts:tokenInfo/@endSent). The same inconsistency applies to paragraph as well. The seciton 4.2.7.9 should invoke fts:paraDistance() with fts:tokenInfo ordered by ($fts:tokenInfo/@startPara, fts:tokenInfo/@endPara). 19494 1 jmdyck 2008-03-16 22:36:40 +0000 (In reply to comment #0) > > However, fts:sentenceDistance() is involked in section 4.2.7.9 with > fts:tokenInfo is order by ('$fts:tokenInfo/@startPos, fts:tokenInfo/@endPos) > instead of ($fts:tokenInfo/@startSent, fts:tokenInfo/@endSent). Can you give an example where these two orderings would lead to different sentence-distances? 19724 2 zhen.liu 2008-04-03 17:44:47 +0000 Per group discussion, we found the distance computation algorithm needs to be revisited as action item 169-01 by Mary Holstege. So we close this bug as invalid.
