Components
System Architecture: Weak Evidence Finder
Query Generator
The query generator outputs two types of queries for each proposition:
- Keyword queries -- Extract keywords from the query sentence [TBD: Stemming? Stopword removal?]
- Template queries -- A template query is simply a tuple (or the sentence) where one or more words in the tuple is replaced with a wild-card operator.
The system will be given a set of rules that specify how to convert a tuple into different template queries.
- Examples
Input: [Sentence: Iron nail is a good conductor of electricity, Tuples: (iron nail, is a good conductor of, electricity)] Output: Q1: (iron *, is a good conductor of, electricity) //Template query Q2: (* nail, is a good conductor of, electricity) //Template query Q3: (iron nail, is a * conductor of, electricity) //Template query Q4: iron * conductor * electricity //Template query Q5: iron or conductor or electricity //Keyword query
