Semantic Relation Detection from Text Task

• Semantic Relation Detection from Text Task: A Semantic Relation Detection from Text Task is theNLP Task to Annotate the Semantic Relations in a Passage.
  • AKA: Relation Detection
  • Context:
    • Input: a Text Corpus and a Semantic Relation Description.
    • Output: the Corpus with [[Tagged?]] Semantic Relations and, optionally, the Relation Pattern used.
    • Can support a Relation Extraction from Text Task.
    • Can be solved automatically by a Relation Detection from Text Algorithm.
    • Can be solved manually by a Domain Expert. (to produce an [[Annotated?]] Corpus).
    • Can be measured in terms of output Correctness (e.g. [[Precission?]]) and [[Resource_Consumption?]] (e.g. [[Computational_Complexity?]] and [[Space_Complexity?]]).
    • The Semantic Relation(s) can be specified to be of the type Domain Dependent Relation or Domain Independent Relation.
    • Benchmark Tasks: ACE Corpus, [[PPLRE_Benchmark_Task?]]
  • Examples:
    • Semantic Relation Detection from Text Task Examples
    • "A cat is a mammal." => TypeOf(cat, mammal). (See: Subsumption Relation)
    • "My cookie has chocolate chips." => Contains(chocolate chips, cookie). (See: Meronymy Relation, Quantification)
    • "Alexander went to Australia." => RelocatedTo(Alexander, Australia).
    • "Microsoft is based in Redmond." => CompanyHeadquarterLocation(Microsoft, Redmond). (See: Domain Specific Relation)
    • "XyaA is one of E. coli’s proteins. It is found in the periplasmic space." => SubcellularLocalization(E. coli, XyaA, periplasmic space). (See: Domain Specific Relation)
    • "Albert's niece Ann got engaged to John." DaughterOfSibling(Albert,Ann) ^ Engaged(Ann, John). (See: Appositive Relation).
    • SemEval-1 Task 4 (Benchmark Task))
