DAF [SIGMOD 2019]

Efficient Subgraph Matching: Harmonizing Dynamic Programming, Adaptive Matching Order, and Failing Set Together

Compile

To compile the query DAG construction program:

Linux: type ./compile.sh or g++ -std=c++11 main.cpp dag.cpp -o program

Binary files of DAF are available

Linux: daf_1min
Windows: daf_1min.exe

Run

To run the query DAG construction program:

Usage: ./program datagraphFile querygraphFile #queries > outputFile

Example: ./program human human_10n 100 > human_10n.dag

To run DAF (time limit is set to 60 sec and #matches is set to 100,000)

Usages:

./daf_1min -d datagraphFile -q querygraphFile -a dagFile -n #queries // with input dagFile
or
./daf_1min -d datagraphFile -q querygraphFile -n # queries // query DAG is constructed by DAF

Examples:

./daf_1min -d human -q human_10n -a human_10n.dag -n 100
./daf_1min -d human -q human_10n -n 100

Compare Results

To evaluate two results for a query set, use sort_result.py script as follows.

./daf_1min -d human -q human_10n -a human_10n.dag -n 100 > result1
./daf_1min -d human -q human_10n -n 100 > result2
python sort_result.py result1 result2
