Back to PPLRE Research Topics.
- Synopsis: Current research assumes that a relationship statements does not involve many intervening words between the entities. The PPLRE Task however involves documents with long sentences. An idea is to divide the sentence into chunks that can be disposed. Sources of information include Semantic Role Labeling and Discourse Relations.
Evidence
- One important source for this added complexity is the fact that we are searching for ternary relationships. For example, in the sentence “We produced recombinant Pa and Pb in Oc, and purified them from the Ld.” .
- See: PPLRE Research Opportunities - Discourse-level Analysis
Counter Evidence
- Many short-distance patterns are also present. For example: “… proteinP is located in the localizationL …". Typically however with only two of the concept types
Examples
- For example: “… x such as y1 and y2, …” (as in: cities such as Vancouver and Seattle), or “… x-based y …” (as in : Redmond-based Microsoft). The PPLRE task however is known to include many long-distance patterns <fill in statistic here>.
