Table 2 Semantic roles
From: Construction of an annotated corpus to support biomedical information extraction
ROLE NAME | DESCRIPTION | EXAMPLE (bold = semantic argument, italics = event central verb) |
|---|---|---|
AGENT | Drives/instigates event | The narL gene product activates the nitrate reductase operon |
THEME | a) Affected by/results from event b) Focus of events describing states | recA protein was induced by UV radiation The ptsH mutant lacks HPr |
MANNER | Method/way in which event is carried out | cpxA gene increases the levels of csgA transcription by dephosphorylation of CpxR |
INSTRUMENT | Used to carry out event | EnvZ functions through OmpR to control NP porin gene expression in E. coli. |
LOCATION | Where complete event takes place | Phosphorylation of OmpR modulates expression of the ompF and ompC genes in Escherichia coli |
SOURCE | Start point of event | A transducing lambda phage was isolated from a strain harboring a glpD"lacZ fusion |
DESTINATION | End point of event | Transcription is activated by binding of the cyclic AMP (cAMP)-cAMP receptor protein (CRP) complex to a CRP binding site |
TEMPORAL | Situates event in time/w.r.t another event | The Alp protease activity is detected in cells after introduction of plasmids |
CONDITION | Environmental conditions/changes in conditions | Strains carrying a mutation in the crp structural gene fail to repress ODC and ADC activities in response to increased cAMP |
RATE | Change of level or rate | marR mutations elevated inaA expression by 10- to 20-fold over that of the wild-type. |
DESCRIPTIVE-AGENT | Descriptive information about AGENT of event | HyfR acts as a formate-dependent regulator |
DESCRIPTIVE-THEME | Descriptive information about THEME of event | The ptsH mutant lacks HPr. |
PURPOSE | Purpose/reason for the event occurring | The fusion strains were used to study the regulation of the cysB gene |
