Question 1
For this Question, I grabbed a lot of sentences from your homeworks, so many thanks to you.
A lot of students think prepositions are good linking words:
- IN
- ... Besides, traffic in the strret network self-organizes in three regions, of fixed car density: ...
- ... Elephants are intelligent enough to be able to detect water flowing underground and have been seen digging up water in a riverbed that has run dry.
- THROUGH
- ... Traffic through Main Street was hampered at times by men mining right in the street, digging holes whereever they reckoned gold would be found ...
- ... The mechanism can also be used to describe phenomena such as losses from the streamflow due to infiltration of river water through the riverbed ...
Some students even proposed to try each preposition word in this list.
Other students argued that action verbs are better than prepositions because they can express more precise relationship.
Most students used linking verb "flow":
- FLOW
- ... In some areas traffic lights are coordinated to facilitate commuter or otherwise heavy traffic flows on major streets ...
- ... The river disappears into a narrow, deep gorge here; it's unbelievable that so much water can flow through such a small riverbed ...
"move" is another choice:
- MOVE
- ... Below him, morning traffic moves along the street ...
- ... As water moves over the riverbed, an area of both swift and still water is created ...
In conclusion, to solve analogy probelm, a linking word is needed. The linking word list can be either statically determined by experience or can be dynamically computed.
