Word Lexicon Co-occurrence Development

Under construction

Introduction: The work of approving word-class co-occurrence patterns as they appear in particular sentences is an aid to the construction of Selection Lists. These lists are used to adjust parse trees so that the words linked together in syntactic arrangements, like an adjective modifying a noun, for example, "make sense" ADJ-N chronic bronchitis approved ADJ:(H-TMDUR) N:(H-DIAG) ADJ-N left injury not approved ADJ:(H-PTAREA) N:(H-INDIC) The latter example occurred in: "a left foot injury" where "left" modifies "foot", not "injury." When a sufficient number of approved patterns is accummulated, they may constitute a trial sel of Selection Lists to be applied to a body of parsed texts to determine whether the use of the lists aids in obtaining correct results, or they be used in other ways to prune existing lists which may have become too permissive in previous work. The results presented here are not complete for the pruning of MLP Selection Lists. The interested user is invited to continue this work with help from the MLP group.      Grammar cooccurrence patterns:       Summary of approved patterns           Cooccurrence of lexically unambiguous words:       MLPC06 coocurrence pattern table            MLPC13 coocurrence pattern table (10 mgh's)            MLPC08 coocurrence pattern table            MLPC13 coocurrence pattern table (10 docs)            MLPC07 coocurrence pattern table            MLPC05 coocurrence pattern table (10 docs)            MLPC16 coocurrence pattern table            MLPC02 coocurrence pattern table           Computed Cooccurrences:       Raw MLPC12 coocurrence pattern editing (10 mgh's)            Raw MLPC08 coocurrence pattern editing            Raw MLPC13 coocurrence pattern editing (10 docs)            Raw MLPC07 coocurrence pattern editing            Raw MLPC05 coocurrence pattern editing (10 docs)            Raw MLPC16 coocurrence pattern editing (10 docs)            Raw MLPC02 coocurrence pattern editing (10 docs)           Med Prepositional Phrases:       Raw idiom preposition coocurrence pattern editing            Raw p1sym coocurrence pattern editing            Raw p2hist coocurrence pattern editing           Ambiguous Cooccurrence Patterns:       Ambiguous MLPC12 coocurrence pattern editing (10 mgh's)            Ambiguous MLPC08 coocurrence pattern editing            Ambiguous MLPC13 coocurrence pattern editing (10 docs)            Ambiguous MLPC07 coocurrence pattern editing (10 docs)            Ambiguous MLPC05 coocurrence pattern editing (10 docs)            Ambiguous MLPC16 coocurrence pattern editing (10 docs)            Ambiguous MLPC02 coocurrence pattern editing (10 docs)
