Abstract
A method includes performing, at a device, an analysis of a domain-specific corpus to identify a base term and a modifier term. The modifier term modifies the base term in at least a portion of the domain-specific corpus. The method also includes accessing, by the device, a first entry in lexicon data. The first entry includes core data corresponding to domain-independent lexical information for the base term. The method further includes adding, based on the analysis, non-core data to the first entry. The non-core data corresponds to domain-specific lexical information for the base term. The non-core data identifies the modifier term as a domain-specific modifier of the base term.
Claims20
A method comprising:
- initiating, at an electronic device, an analysis of a domain-specific corpus to identify a base term and a modifier term, wherein the modifier term modifies the base term in at least a portion of the domain-specific corpus;
- accessing, by the electronic device, a first entry in lexicon data, wherein the lexicon data is accessible by the electronic device prior to the initiating and is configured for use at the electronic device in a language processing operation, the first entry including core data corresponding to domain-independent lexical information for the base term;
- adding, based on the analysis, non-core data to the first entry, the non-core data corresponding to domain-specific lexical information for the base term, wherein the non-core data identifies the modifier term as a domain-specific modifier of the base term;
- and
- processing text at the electronic device based on the non-core data.
A method comprising:
- analyzing, at a device that includes a parser, a domain-specific corpus to identify a base term and a modifier term, wherein the modifier term modifies the base term in at least a portion of the domain-specific corpus;
- accessing a first entry in lexicon data, the lexicon data accessible by the device prior to the analyzing, and the first entry including core data corresponding to domain-independent lexical information for the base term;
- adding, based on the analyzing, non-core data to the first entry, the non-core data corresponding to domain-specific lexical information for the base term, and the non-core data identifying the modifier term as a domain-specific modifier of the base term;
- and
- performing a language processing operation, at the parser, based on the lexicon data.
