| Abstract | Mechanical patent literature contains a large amount of domain knowledge where component names exist as information units.Being flexible and changeable, the word formatting of component name represents the characteristics of uniqueness, complexity and lesser-known expressions.The challenge of accurate recognition of component names by computers becomes an obstacle to patent knowledge mining.In order to propose an efficient method to recognize component names, the features of word formation in patent text statements are analyzed and extracted.Starting with external words related to component names, characters on the left side of the appended drawing reference signs（ADRS） are identified.Accordingly, candidate names are automatically retrieved from texts, and the set of candidate names are constructed.An algorithm of word frequency difference is proposed to filter redundant characters in the set of candidate names.By building left-segmentation library（LSL） dynamically, redundant characters which are not filtered |
